The purpose of this meta-analysis was to explore whether cervical disc arthroplasty (CDA) was superior to anterior cervical discectomy and fusion (ACDF) in reducing secondary surgery. PubMed, EMBASE, and the Cochrane Library databases were systematically searched. Outcomes were reported as relative risk (RR) with the corresponding 95% confidence interval (CI). The pooled data was calculated using a random-effect model. We also used the trial sequential analysis (TSA) to further verify our results and obtain more moderate estimates...

OBJECTIVE: Iatrogenic radial nerve injury is a great challenge for orthopaedic surgeons who deal with distal-third diaphyseal humerus fractures. Conventional open reduction and internal fixation (ORIF) remains the gold standard, but complications such as nonunion and iatrogenic radial nerve injury still occur. We fixed the fractures with a lateral locking compression plate (LCP) subcutaneously after small incision reduction to protect the radial nerve. This study reports the clinical and radiographic outcomes of our modified method...

OBJECTIVE: To identify factors that influence shoulder balance and to determine whether a model can be made to predict shoulder balance after corrective surgery. METHODS: This is a retrospective study in which we examined the records of with adolescent idiopathic scoliosis (AIS) patients who underwent single posterior spinal correction and fusion using all pedicle screws with derotation in our institution between January 2008 and June 2010. For the radiographic outcome measurement, we measured the preoperative lumbar curve, the main thoracic curve, and their difference (L_TH_D), and the degree of correction of the lumbar curve, the main thoracic curve, and their difference (c_L_TH_D) to evaluate their influence on postoperative shoulder balance...

The clinical incidence of tumors in the manubrium is not high. Regardless of whether the tumor is primary or metastatic, the tumor should be completely removed as long as the patient is able to tolerate the surgery. This procedure can lead to sternal defects. Deciding on the method of defect reconstruction is a critical problem that clinicians face. In this , to reduce the limitations of the patient's upper body movement after surgery due to the inflexibility in the connections of the sternal prosthesis, we created a prosthesis using a computer-assisted design method and a 3-D technique, to completely preserve the agility of the sternum and maximize the patient's post-operational movement...

OBJECTIVES: Knee osteoarthritis (OA) is a prevalent disease in the elderly, causing pain and contributing to poor quality of life. Surgical intervention, such as knee arthroplasty, can be used in those with end-stage knee OA. Total knee arthroplasty (TKA) is one of the most common surgical procedures for end-stage knee OA, with promising clinical outcomes. However, a large proportion of patients with isolated compartment OA can be treated with unicompartmental knee arthroplasty (UKA) instead...

OBJECTIVES: Femoral intertrochanteric fractures are among the most common fractures in the elderly. There are various classification systems in intertrochanteric fractures. The aim of these classification systems is to help surgeons choose an appropriate treatment. The treatment of femoral intertrochanteric fractures depends on the results of a stability evaluation using imaging studies. However, it is difficult to evaluate the true fracture line using plain X-ray films, especially on the sagittal plane and for intertrochanteric fractures with complex morphologies...

Gorham-Stout disease (GSD) is an extremely rare bone condition of unknown etiology characterized by spontaneous and progressive resorption of bones. GSD can occur at any age and is not related to gender, genetic inheritance, or race. Any part of the skeleton can be affected and the symptoms correlate with the sites involved. The diagnosis of GSD is established based on the combination of clinical, radiologic, and histologic features after excluding other diseases. Because of its rarity, current knowledge is limited to case reports and there is no agreement on the best strategy for treatment...

OBJECTIVE: To evaluate the correlation between features of knee joint rheumatoid arthritis (RA) identified on MRI and histological examination as a means of elucidating the pathogenesis of joint destruction in RA. METHODS: This is a prospective analysis of 26 knee joints of 22 patients who underwent total knee arthroplasty (TKA) for the treatment of RA. Based on the degree of destruction of articular cartilage and the menisci, the occurrence of bone marrow edema and bone erosion, and synovial thickening, the stage of the knee joints were classified using MRI by two radiologists...

Diaphyseal defects in long bones of extremities following segmental resection are very common in the clinic, and reconstruction remains a great challenge. Although there are many treatments for diaphyseal defects at present, reconstruction with an intercalary endoprosthesis may be an optimal method. We demonstrate a surgical technique for reconstruction of a humeral shaft defect with an intercalary endoprosthesis following tumor resection, and achieve a good clinical outcome. We conclude that in comparison with other methods, reconstruction with an intercalary endoprosthesis is simple, effective, and allows for earlier weight bearing and more rapid restoration of function...

OBJECTIVES: There are several types of metaphyseal chondrodysplasia and various clinical types have been differentiated. The Schmid type of metaphyseal chondrodysplasia is the most common. Diffuse metaphyseal flaring, irregularity, and growth plate widening, which are most severe in the knees, are the most striking radiological features of this disease. The Schmid type of metaphyseal dysostosis is characterized by failure of normal mineralization of the zone of provisional calcification, leading to widened physes and enlarged knobby metaphyses, effectively causing shortening of the tubular bones, splaying of the metaphyses, coxa vara, and bow legs...

OBJECTIVE: Cervical spondylosis affects a huge proportion of the middle-aged population. Degenerative changes can occur in multiple regions of the cervical spine typically affecting the joints, intervertebral discs and endplates. These changes lead to compression of adjacent nervous structures, which results in radiculopathic and myelopathic pain. Various treatment modalities are currently available with non-surgical approaches the initial go to if there is no symptomatic cord compression...
