OBJECTIVE: To explore the clinical efficacy of double-plate fixation for the treatment of old tibial plateau fractures with Schatzker type IV through anterior midline and posteromedial approaches. METHODS: From July 2013 to July 2015, 15 patients with old tibial plateau fractures were treated with internal fixation using locking reconstructive plate for the posteromedial fragment and anatomical locking plate for anteromedial fragment through antero midline and posteromedial approaches...

Rheumatoid arthritis (RA) is a most common inflammatory joint disease with direct invasion of joint synovial membrane, cartilage and bone. Currently, although the RA mitigation drugs are being improved continously, but these drugs only can delay the development of joint dysfunction. Total hip arthroplasty or total knee arthroplasty(THA or TKA) has become the only choices for patients with advanced RA, and the joint function and deformity of the patients after surgical treatment can be improved to some extent...

Background: Data on indication of Unicompartmental Knee Arthroplasty (UKA) in the Asian population are currently not available. The current paper evaluates patients undergoing knee replacement at a Chinese Orthopaedic Specialty Hospital to report the percentage of patients who meet radiographic and clinical indication criteria for UKA. Methods: Over a one-year period 463 consecutive patients (515 knees) underwent primary knee replacement surgery. Clinical data were recorded and preoperative radiographs were assessed...

OBJECTIVE: To evaluate the clinical efficacy of open supracondylar osteotomy of the femoral condyle for the treatment of valgus knee osteoarthritis. METHODS: From April 2008 to June 2015, 21 patients with valgus knee osteoarthritis underwent an open wedge femoral supracondylar osteotomy using the distal femur dissection plates combined with autologous iliac bone graft for the bone defect. There were 8 males (8 knees) and 13 females (15 knees), ranging in age from 30 to 54 years old, with a mean age of 41...

OBJECTIVE: To analyze the clinical outcome of kyphoplasty on costal pain which develops following thoracic osteoporotic compression fractures and evaluate the factors related to costal pain. METHODS: From May 2014 to May 2016, a total of 188 patients with thoracic osteoporotic compression fractures undergoing kyphoplasty were reviewed retrospectively. The patients were divided into two groups: the costal pain group included patients who had costal pain after a vertebral fracture and the no costal pain group included patients without costalgia...

PURPOSE: Spine duplication is a very rare condition with the literature being composed of only case reports. All previously reported cases were thoracolumbar spine duplications. Here, we report cervicothoracic spine duplication in a neurological intact male. According to our knowledge, it is the first case in the literature of cervicothoracic spine duplication. CLINICAL PRESENTATION: A 3-year-old patient presented to a primary physician with a complaint of short stature...

Disabling pansclerotic morphoea (DPM) of childhood is a severe and often fatal variant of deep morphoea. It usually starts in childhood and rarely seen in adults. The course of the disease is progressive with lifelong morbidity in the form of joint contractures and immobility. The causes of mortality include complications such as sepsis, gangrene and cardiopulmonary involvement. Herein, we discuss the case of a 15-year-old girl with limb deformity and finger contractures, that is, bone involvement. The diagnosis of DPM of childhood was fortuitously made after the correction of limb deformity, when the patient was seen in the dermatology department for evaluation of skin discolouration on the thighs...

BACKGROUND: Context: Achieving a successful spinal fusion requires the proper biologic and biomechanical environment. Optimizing load-sharing in the interbody space can enhance bone formation. For anterior cervical discectomy and fusion (ACDF), loading and motion are largely dictated by the stiffness of the plate which can facilitate a balance between stability and load-sharing. The advantages of load-sharing may be substantial for patients with comorbidities and in multi-level procedures where pseudarthrosis rates are significant...

Paranasal sinuses are highly variable among living and fossil hominins and their function(s) are poorly understood. It has been argued they serve no particular function and are biological 'spandrels' arising as a structural consequence of changes in associated bones and/or soft tissue structures. In contrast, others have suggested that sinuses have one or more functions, in olfaction, respiration, thermoregulation, nitric oxide production, voice resonance, reduction of skull weight, and craniofacial biomechanics...

PURPOSE: Documents indicated that the average prevalence of intraspinal neural axis abnormalities (INAAs) in presumed idiopathic scoliosis (PIS) patients was about 17.7%. However, paucity study focuses on the incidence of INAAs in severe spinal deformity (SSDs). In this study, we investigate the incidence of intraspinal neural axis abnormalities (IINAAs) and the clinical relevance in SSD at a single center. METHODS: All the patients with SSDs admitted for spinal surgery were evaluated from 2003 to 2014...

CASE: A patient presenting with an infected diabetic foot ulcer and Staphylococcus aureus chronic osteomyelitis was studied to validate the clinical importance of bacterial colonization of osteocytic-canalicular networks, as we recently reported in a mouse model. We utilized transmission electron microscopy to describe the deformation of S. aureus, from round cocci to rod-shaped bacteria, in the submicron osteocytic-canalicular networks of amputated bone tissue. CONCLUSION: To our knowledge, this is the first evidence of S...

BACKGROUND: Impaired bone quality is associated with poor outcome of spinal surgery. The aim of the study was to assess the bone mineral status of patients scheduled to undergo spinal surgery and to report frequencies of bone mineral disorders. METHODS: We retrospectively analyzed the bone mineral status of 144 patients requiring spinal surgery including bone mineral density by dual-energy X-ray absorptiometry (DXA) as well as laboratory data with serum levels of 25-hydroxyvitamin D (25-OH-D), parathyroid hormone, calcium, bone specific alkaline phosphate, osteocalcin, and gastrin...

BACKGROUND: Bone impairment appears to be a novel complication of nephropathic cystinosis despite cysteamine therapy. Its exact underlying pathophysiology is nevertheless unclear. The objective of this study was to evaluate bone status among patients included in the French Crystobs study. METHODS: In addition to clinical data, bone status was evaluated using biomarkers (ALP, PTH, 25-D, 1-25D, FGF23), DXA (spine and total body), and high-resolution peripheral quantitative computed tomography (HR-pQCT) at the tibia and radius...

Recent studies have shown great potential of Mg matrix composites for biodegradable orthopedic devices. However, the poor structural integrity of these composites, which results in excessive localized corrosion and premature mechanical failure, has hindered their widespread applications. In this research, an in-situ Powder Metallurgy (PM) method was used to fabricate a novel biodegradable Mg-bredigite composite and to achieve enhanced chemical interfacial locking between the constituents by triggering a solid-state thermochemical reaction between Mg and bredigite particles...

Titanium cages with 3-D printed trussed open-space architectures may provide an opportunity to deliver targeted mechanical behavior in spine interbody fusion devices. The ability to control mechanical strain, at levels known to stimulate an osteogenic response, to the fusion site could lead to development of optimized therapeutic implants that improve clinical outcomes. In this study, cages of varying design (1.00 mm or 0.75 mm diameter struts) were mechanically characterized and compared for multiple compressive load magnitudes in order to determine what impact certain design variables had on localized strain...

BACKGROUND: Clinical results have shown that different vertebral heights have been restored post-augmentation of osteoporotic vertebral compression fractures (OVCFs) and the treatment results are consistent. However, no significant results regarding biomechanical effects post-augmentation have been found with different types of vertebral deformity or vertebral heights by biomechanical analysis. Therefore, the present study aimed to investigate the biomechanical effects between different vertebral heights of OVCFs before and after augmentation using three-dimensional finite element analysis...
