Duration of antiresorptive activity of zoledronate in postmenopausal women with osteopenia: a randomized, controlled multidose trial.

Intravenous zoledronate 5 mg annually reduces fracture risk, and 5 mg every 2 years prevents bone loss, but the optimal dosing regimens for these indications are uncertain.

Usefulness of titanium mesh cage for posterior C1-C2 fixation in patients with atlantoaxial instability.

The aim of this study was to investigate the usefulness of titanium mesh cage as an interlaminar spacer combined with nitinol shape memory loop fixation in patients with atlantoaxial instability.From April 2009 to March 2017, among the patients with atlantoaxial instability, a total of 30 patients were treated by nitinol shape memory loop fixation combined with titanium mesh cage as a spacer. We retrospectively reviewed 30 enrolled patients. Successful fusion was determined as improvement of symptoms and radiologic findings of bone fusion. We also reviewed surgical complications, instrumentation failure, bony fusion rate, and posterior atlantodental interval (PADI).After surgery, the symptoms of all patients significantly improved. Successful fusion was documented throughout the follow-up period. Evidence of solid bridging bone was found, and no instability was seen on flexion-extension radiographs and callus formation on 3D cervical spine computed tomography (CT) 6 months postoperatively in all cases. No surgical complications were observed. No cases of instrumentation failure were observed. The mean PADI also improved significantly to 22.45 ± 1.11 mm 6 months postoperatively compared with the preoperative value of 18.37 ± 1.16 mm (P < .05).We obtained a good fusion rate by using titanium mesh cage spacer with nitinol shape memory alloy loop in patients with atlantoaxial instability. This technique can help surgeons in avoiding vertebral artery injury and reducing bleeding and operation time. Therefore, we suggest that titanium mesh cage spacer combined with nitinol shape memory alloy loop can be a good substitute of autograft for C1-C2 fusion in treating atlantoaxial instabilities.

Secondary hypertrophic osteoarthropathy caused by non-pleural or pulmonary tumors.

Hypertrophic osteoarthropathy (HOA) is a rare paraneoplastic syndrome characterized by digital clubbing, periosteal reaction, polyarthralgia, arthritis, and synovitis. Herein, we report a case series of patients with secondary HOA caused by non-pleural or pulmonary tumors.The radiologic databases of 2 tertiary university hospitals were retrospectively screened for secondary HOA patients. In addition, a systemic review of the published case reports. Only HOA cases with non-pleural or pulmonary malignancies were involved into the study. HOA in primary pleural or pulmonary malignant or benign disorders, as well in inflammatory diseases were excluded. In all cases, plain radiography was performed and clinical signs were documented.In our databases, 6 patients with secondary HOA were identified. In addition, the systemic review yielded 24 eligible patients. The most prevalent primary tumors were nasopharyngeal carcinoma and esophageal cancer in 6 patients (20%), respectively. In 17 patients, (56.7%) HOA was associated with lung metastases, and in 10 patients (33.3%), no lung metastases were detected. In 14 patients (46.7%), HOA was symptomatically before a tumor diagnosis was made. Plain radiography displayed typically features with periostal enlargement in every case.This study is the first report about secondary HOA caused by non-pleural or pulmonary tumors. Various primary tumors were identified, including several rare tumors such as sarcomas. HOA is a rare disorder with typically radiologically findings, which is not only associated with lung cancer or pleural mesothelioma and can even occur in tumor patients without lung metastasis.

Surgical treatment for lumbar hyperlordosis after resection of a spinal lipoma associated with spina bifida: A case report.

A hyperlordosis deformity of the lumbar spine is relatively rare, and surgical treatment has not been comprehensively addressed. In this case report, we describe the clinical presentation, surgical treatment, and medium-term follow-up of a patient presenting with a progressive lumbar hyperlordosis deformity after resection of a spinal lipoma associated with spina bifida.

Connecting the Dots.

Association between oropharyngeal carriage of Kingella kingae and osteoarticular infection in young children: a case-control study.

Kingella kingae has been increasingly identified in patients with osteoarticular infections. Our main objective was to evaluate the association between carriage of K. kingae in the oropharynx of preschool children and osteoarticular infections.

To develop a scoring system to predict bone metastasis after radical resection within 5 years.

Will Chinese external therapy with compound Tripterygium wilfordii hook F gel safely control disease activity in patients with rheumatoid arthritis: design of a double-blinded randomized controlled trial.

Chinese external therapy (CET) is a topical application with mainly Chinese herb medicine therapy with thousands of years of historical implications and is a clinical routine that is commonly used for relieving joint-related symptoms in patients with arthritis in Chinese hospitals. However, there is a paucity of modern medical evidence to support its effectiveness and safety. Thus, we propose to implement a randomized, double-blinded, placebo-controlled clinical trial in patients with rheumatoid arthritis (RA) using, as the experimental intervention, topical application of a hospital-compounded gel preparation of Tripterygium wilfordii Hook F (TwHF).

Fixed-functional appliance treatment combined with growth hormone therapy.

The purpose of this study was to illustrate the effects of growth hormone (GH) therapy and fixed functional appliance treatment in a 13-year-old Class II malocclusion patient without GH deficiency. GH has been shown to effectively increase endochondral growth and induce a more prognathic skeletal pattern. Although a major concern in Class II retrognathic patients is chin deficiency, long-term studies have shown that the mandibular growth enhancement effects of functional appliances are clinically insignificant. This case report demonstrates that the mandible grew significantly during fixed functional appliance treatment combined with GH therapy, with stable results during 2 years 11 months of retention. More studies are needed to evaluate GH therapy as a supplement in Class II treatment.

Three-dimensional evaluation of the airway spaces in patients with and without cleft lip and palate: A digital volume tomographic study.

Patients with cleft lip and palate (CLP) suffer from several esthetic and functional challenges. Comprehensive treatment of these patients involves orthognathic surgery that may lead to velopharyngeal insufficiency or reduction in lower airway. Several cases of airway insufficiency, velopharyngeal incompetence, snoring, hypopnea, and obstructive sleep apnea have been reported in subjects with CLP. The aim of this study was to compare the anteroposterior dimensions of the oropharyngeal airway at 5 levels, the height of the oropharyngeal column, and the volume of the oropharyngeal airway in subjects with and without CLP.

Bone-anchored maxillary protraction therapy in patients with unilateral complete cleft lip and palate: 3-dimensional assessment of maxillary effects.

The aim of this study was to 3-dimensionally assess the treatment outcomes of bone-anchored maxillary protraction (BAMP) in patients with unilateral cleft lip and palate.

Bortezomib-Induced Muscle Toxicity in Multiple Myeloma.

Multiple myeloma (MM) accounts for ∼13% of all hematologic malignancies. Bortezomib treatment is effective in MM, but can be complicated with neurological side effects. We describe a patient with symptomatic MM who had a reversible metabolic myopathy associated with bortezomib administration and pathologically characterized by excessive storage of lipid droplets together with mitochondrial abnormalities. In a single-center prospective study, 14 out of 24 patients with symptomatic MM were treated with bortezomib and, among these, 7 developed muscular signs and/or symptoms. The myopathy was characterized by a proximal muscle weakness involving lower limbs and was an early complication. Complete resolution of muscle weakness occurred after treatment discontinuation. Conversely, none of the patients who received a treatment without bortezomib developed muscular symptoms. Experimental studies demonstrate that in primary human myoblasts bortezomib at low concentrations leads to excessive storage of lipid droplets together with structural mitochondrial abnormalities, recapitulating the pathologic findings observed in patient's muscle. Our data suggest that patients treated with bortezomib should be monitored for muscular signs and/or symptoms and muscle weakness should alert the clinician to the possibility of myopathy. Bortezomib-induced metabolic myopathy is a potentially reversible entity with important implications for management and treatment of patients with MM.

Management of Metastatic Spinal Cord Compression.

Cancer metastasis is a key event in tumor progression associated not only with mortality but also significant morbidity. Metastatic disease can promote end-organ dysfunction and even failure through mass effect compression of various vital organs including the spinal cord. In such cases, prompt medical attention is needed to restore neurological function, relieve pain, and prevent permanent damage. The three therapeutic approaches to managing metastatic spinal cord compression include corticosteroids, surgery, and radiation therapy. Although each may improve patients' symptoms, their combination has yielded the best outcome. In cancer patients with clinical suspicion of spinal cord compression, dexamethasone should be initiated followed by surgical decompression, when possible, and radiation. The latter becomes the preferred treatment in patients with inoperable disease.

Late presentation of developmental dysplasia of the hip : a 15-year observational study.

Despite the presence of screening programmes, infants continue to present with late developmental dysplasia of the hip (DDH), the impact of which is significant. The aim of this study was to assess infants with late presenting dislocation of the hip despite universal clinical neonatal and selective ultrasound screening.

Is it safe to preserve the deltoid when resecting the proximal humerus for a primary malignant bone tumour? A comparative study.

Resection of the proximal humerus for the primary malignant bone tumour sometimes requires en bloc resection of the deltoid. However, there is no information in the literature which helps a surgeon decide whether to preserve the deltoid or not. The aim of this study was to determine whether retaining the deltoid at the time of resection would increase the rate of local recurrence. We also sought to identify the variables that persuade expert surgeons to choose a deltoid sparing rather than deltoid resecting procedure.

Vascularised fibular grafts for reconstruction of extremity bone defects after resection of bone and soft-tissue tumours : a single institutional study of 49 patients.

The aims of this study were to analyse the long-term outcome of vascularised fibular graft (VFG) reconstruction after tumour resection and to evaluate the usefulness of the method.

Venous thromboembolism in adult elective spinal surgery: a tertiary centre review of 2181 patients.

To evaluate the incidence of primary venous thromboembolism (VTE), epidural haematoma, surgical site infection (SSI), and 90-day mortality after elective spinal surgery, and the effect of two protocols for prophylaxis.

Revision anatomical reconstruction of the lateral ligaments of the ankle augmented with suture tape for patients with a failed Broström procedure.

The aim of this prospective study was to evaluate the intermediate-term outcomes after revision anatomical ankle ligament reconstruction augmented with suture tape for a failed modified Broström procedure.

No difference in time-dependent improvement in functional outcome following closing wedge versus opening wedge high tibial osteotomy: a randomised controlled trial with two-year follow-up.

The aim of this prospective randomised study was to compare the time course of clinical improvement during the first two years following a closing or opening wedge high tibial osteotomy (HTO). It was hypothesised that there would be no differences in clinical outcome between the two techniques.

Factors affecting the potential for posterior bony impingement after total hip arthroplasty.

Our aim was to evaluate the radiographic characteristics of patients undergoing total hip arthroplasty (THA) for the potential of posterior bony impingement using CT simulations.

The mucopolysaccharidoses: advances in medical care lead to challenges in orthopaedic surgical care.

The mucopolysaccharidoses (MPS) are a group of inherited lysosomal storage disorders with clinical manifestations relevant to the orthopaedic surgeon. Our aim was to review the recent advances in their management and the implications for surgical practice. The current literature about MPSs is summarised, emphasising orthopaedic complications and their management. Recent advances in the diagnosis and management of MPSs include the recognition of slowly progressive, late presenting subtypes, developments in life-prolonging systemic treatment and potentially new indications for surgical treatment. The outcomes of surgery in these patients are not yet validated and some procedures have a high rate of complications which differ from those in patients who do not have a MPS. The diagnosis of a MPS should be considered in adolescents or young adults with a previously unrecognised dysplasia of the hip. Surgeons treating patients with a MPS should report their experience and studies should include the assessment of function and quality of life to guide treatment.

Optimizing Cholesterol Treatment in Patients With Muscle Complaints.

Statins are highly effective for preventing cardiovascular events by reducing low-density lipoprotein cholesterol (LDL-C). However, many patients taking statins report muscle-related symptoms that prevent the use of guideline recommended doses. Patients with reported intolerance to statins have a high risk of cardiovascular events. Clinical strategies that optimize cardiovascular risk reduction through LDL-C lowering need to be applied in patients experiencing intolerable side effects that they attribute to statins. In this paper, the authors review definitions of statin intolerance, propose algorithms to better define statin intolerance, and describe approaches to optimize cardiovascular risk reduction among individuals reporting statin-associated muscle symptoms.

Microscope-assisted anterior cervical discectomy and fusion combined with posterior minimally invasive surgery through tubular retractors for multisegmental cervical spondylotic myelopathy: A retrospective study.

This study aimed to investigate the clinical efficacy and outcome of combined microscope-assisted anterior cervical discectomy and fusion (ACDF) with posterior minimally invasive surgery through tubular retractors for patients with multisegmental cervical spondylotic myelopathy (MCSM).This retrospective study included 28 patients (19 males and 9 females) with multisegmental cervical spondylotic myelopathy, who underwent combined microscope-assisted ACDF with posterior minimally invasive surgery through tubular retractors in our single center between January 2012 and December 2016. The evaluated postoperative clinical outcomes were operation time, length of hospitalization, blood loss, levels of creatine phosphokinase isoenzyme MM (CPK-MM), Japanese Orthopedic Association (JOA) scores, visual analogue scale (VAS) scores, Cobb angle of C2-C7, and radiological assessments (included X-rays, computed tomography scans, and magnetic resonanceimaging images).The mean surgery time was 198.42 ± 17.53 minutes, the average hospitalization length of hospital was 7.59 ± 1.38 days, and the mean follow-up time was 13 ± 2.45 months. On average, about 36.42 ± 10.15 mL of blood was lost and CPK-MM increased to 331.75 ± 23.15 IU/mL postoperatively (P < .001). The mean modified JOA scores increased from 8.21 ± 0.69 preoperatively to 13.96 ± 1.57 postoperatively (P < .001), whereas the mean VAS scores decreased from 6.64 ± 1.28 preoperatively to 0.39 ± 0.50 postoperatively (P < .001). Cobb angle of C2-C7 increased from 13.86° ± 5.69° preoperatively to 14.10° ± 5.56° postoperatively (P = .16).In conclusion, combined microscope-assisted ACDF with posterior minimally invasive surgery through tubular retractors appears to be a safe and effective treatment for patients with MCSM.

Flatfoot in the contralateral foot in patients with unilateral idiopathic clubfoot treated using the foot abduction brace.

While the foot abduction brace (FAB) plays an important role in the Ponseti method, the true function of the FAB in the treatment of idiopathic clubfoot remains unknown. In our clinical experience, we have noted that many patients with unilateral idiopathic clubfoot developed significant flatfoot in the contralateral foot during brace treatment. The purpose of this study was to investigate the natural history of the contralateral foot development during and after brace wear. We also discuss the effect of the FAB on the contralateral foot.We retrospectively reviewed 21 contralateral feet of 21 patients with unilateral idiopathic clubfoot who were treated using the Ponseti method and were conservatively followed up until the FAB was taken off (6 years of age or older). We evaluated flatfoot indicators of the contralateral foot on standing radiographs during and after brace wear and compared them against the normal reference ranges. We also evaluated the changes in the flatfoot indicators of the contralateral foot during and after brace wear.Although there was a significant difference in the flatfoot indicators between the contralateral foot and normal reference ranges during brace wear, there was no significant difference in the flatfoot indicators after brace wear. While there was no significant improvement in flatfoot indicators of the contralateral foot during brace wear, there was a significant improvement or a trend to improve after brace wear. There was no significant correlation between the contralateral flatfoot and original joint laxity.Significant flatfoot deformity was observed in the contralateral foot during brace wear. The contralateral flatfoot persisted during brace wear and improved to within normal reference ranges after brace wear. Our findings suggest that the FAB may influence the development of the contralateral foot, leading to the flatfoot.

Are programmed cell death 1 gene polymorphisms correlated with susceptibility to rheumatoid arthritis?: A meta-analysis.

Several studies investigated the relationship between programmed cell death 1 (PDCD1) gene polymorphisms and rheumatoid arthritis (RA) risk, but the results were controversial. To explore whether PDCD1 gene polymorphisms have an effect on RA risk, we conducted this meta-analysis to investigate the relationships between PDCD1 polymorphisms (rs36084323 [PD-1.1 G/A], rs11568821 [PD-1.3 G/A] and rs2227981 [PD-1.5 C/T]) and RA risk under 4 genetic models.

Concomitant occurrence of FXTAS and clinically defined sporadic inclusion body myositis: report of two cases.

This report describes unique presentations of inclusion body myositis (IBM) in two unrelated patients, one male and one female, with genetically and histologically confirmed fragile X-associated tremor/ataxia syndrome (FXTAS). We summarize overlapping symptoms between two disorders, clinical course, and histopathological analyses of the two patients with FXTAS and sporadic IBM, clinically defined per diagnostic criteria of the European Neuromuscular Centre. In case 1, a post-mortem analysis of available brain and muscle tissues is also described. Histopathological features (rimmed vacuoles) consistent with clinically defined IBM were detected in both presented cases. Postmortem testing in case 1 revealed the presence of an FMR1 premutation allele of 60 CGG repeats in both brain and skeletal muscle samples. Case 2 was a premutation carrier with 71 CGG repeats who had a son with FXS. Given that FXTAS is associated with immune-mediated disorders among premutation carriers, it is likely that the pathogeneses of IBM and FXTAS are linked. This is, to our knowledge, the first report of these two conditions presenting together, which expands our understanding of clinical symptoms and unusual presentations in patients with FXTAS. Following detection of a premutation allele of the FMR1 gene, FXTAS patients with severe muscle pain should be assessed for IBM.

Impact of the quantity of intradiscal cement leak on the progression of intervertebral disc degeneration.

Introduction We aim to assess the impact of the quantity of intradiscal cement leak during kyphoplasty on the rate of progression of degenerative changes in the affected disc. Methods Of 316 kyphoplasty procedures, we identified 32 episodes of intradiscal cement leak in 26 patients. The quantity of cement leaked was graded from I to IV. Disc degenerative changes were assessed at presentation and follow-up using radiographical scoring and magnetic resonance imaging (MRI) grading systems. Data for low-grade leaks (grade I) were compared with the medium- and high-grade leaks (grades II-IV) using a chi-squared test. Results Median follow-up radiographic and MRI assessments were made at 18 and 21 months, respectively. Medium- and high-grade leaks were associated with a significantly higher radiographic disc degeneration scores compared with low-grade leaks (P = 0.04295) but no difference was found in MRI disc degeneration grades and in adjacent vertebral fracture rates. Conclusions Our findings indicate that the quantity of cement leaking into the disc space significantly influences the rate of progression of disc degeneration.

Rotator cuff surgery in patients with rheumatoid arthritis: clinical outcome comparable to age, sex and tear size matched non-rheumatoid patients.

Aims This study aimed to compare the clinical outcomes of rotator cuff repair in patients with rheumatoid arthritis with those of patients who have no known history of the disease. We hypothesised that the functional outcomes are comparable between patients and without rheumatoid arthritis and may be affected by the level of disease activity, as assessed from C-reactive protein (CRP) level and history of systemic steroid intake. Patients and methods We conducted a retrospective review of the institutional surgical database from May 1995 to April 2012. Twenty-nine patients with rheumatoid arthritis who had rotator cuff repair were enrolled as the study group. Age, sex, and tear size matched patients with no disease who were selected as the control group. The mean duration of follow-up was 46 months (range 24-92 months). Clinical outcomes were assessed with the American Shoulder and Elbow Surgeons (ASES) questionnaire, Constant score and visual analogue scale (VAS). All data were recorded preoperatively and at regular postoperative follow-up visits. CRP was measured preoperatively as the disease activity marker for rheumatoid arthritis. Medication history was thoroughly reviewed in the study group. Results In patients with rheumatoid arthritis, all shoulder functional scores improved after surgery (ASES 56.1-78.1, Constant 50.8-70.5 and VAS 5.2-2.5; P < 0.001). The functional outcome of surgery in patients with rheumatoid arthritis was comparable to that of the control group (difference with control: ASES 78.1 vs. 85.5, P = 0.093; Constant 70.5 vs. 75.9, P = 0.366; VAS 2.5 vs. 1.8, P = 0.108). Patients with rheumatoid arthritis who had an elevated CRP level (> 1 mg/dl) showed inferior clinical outcomes than those with normal CRP levels. Patients with a history of systemic steroid intake showed inferior functional outcomes than those who had not taken steroids. Conclusions Surgical intervention for rotator cuff tear in patients with rheumatoid arthritis improved the shoulder functional outcome comparable to that in matched patients without rheumatoid arthritis. Elevated preoperative CRP level and history of systemic steroid intake portend inferior functional outcome in patients with rheumatoid arthritis.

Pyomyositis of the pectineus muscle in an adolescent male.

The 'irritable hip' continues to pose a challenge for clinicians. Even with predictive clinical algorithms, decision making can be difficult. Emergency treatment is required if septic arthritis is suspected. Other differential diagnoses such as transient synovitis, pyomyositis of the pelvic girdle muscles and osteomyelitis must be considered in order to help guide appropriate investigations and allow early treatment. We report the case of a 13-year-old boy presenting to our institution with an acutely painful left hip but still able to weight bear. Despite a fever and raised inflammatory markers, the clinical examination did not correspond to that of an infected hip joint. Urgent magnetic resonance imaging (MRI) confirmed pyomyositis of the pectineus muscle. To our knowledge, this is the first reported case in the literature. The child was treated with seven days of intravenous antibiotics. There was a good clinical response as well as normalisation of the C-reactive protein level and white cell count. The patient was discharged home with a further week of oral antibiotics. Follow-up MRI at two weeks demonstrated a dramatic reduction in the inflammation of the pectineus. At the clinic follow-up appointment, the child was asymptomatic and back to normal function. Pyomyositis is typically found in tropical areas but its rates in temperate climates have been rising. It usually affects large groups of muscles such as the quadriceps and gluteal muscles. MRI is the gold standard investigation. If diagnosed early, the condition can be treated successfully with intravenous antibiotics alone. Given the widespread availability of MRI, we recommend its increased use to distinguish between pyomyositis and other paediatric hip pathologies.

Bone metastases of the hand.

Introduction The aim of this study was to identify patients with malignant hand lesions, establish the proportions of those that were metastases and review their clinical course. Methods A retrospective search of a prospective tumour database was carried out to identify all patients treated at our unit with hand metastases. Patient demographics were recorded including site of primary malignancy, region of the hand involved, management of their metastasis and clinical outcome. Results Overall, 149 patients were identified with a malignant tumour of the hand. Ten had a metastatic lesion. There were 3 women and 7 men with a median age of 68 years (range: 28-91 years) at presentation. All presented with non-mechanical hand pain while four had pain and swelling. The median interval from symptom onset to diagnosis was eight weeks. The minimum follow-up duration was four months. Three patients had no history of malignancy. Of the remaining seven patients, three had other known metastases. Six patients underwent solely palliative radiotherapy. Three patients had amputation. One was treated with surgical excision and radiotherapy. One had an amputation and axillary node clearance. All but one patient had died by the time of the latest follow-up appointment. The median time to death following identification of acrometastases was 18 months. Sites of primary disease were skin (n=4), lung (n=3), kidney (n=2) and neuroendocrine system (n=1). The thumb was the most commonly affected location. Conclusions This study demonstrates that patients presenting with non-mechanical hand pain should be considered to have a malignant process until proved otherwise, particularly in patients with thumb symptoms and a history of prior malignancy.
