BACKGROUND: Congenital pseudoarthrosis of the clavicle (CPC) is rare and may require treatment, usually because of an unacceptable appearance or occasionally because of pain in an adolescent patient. Spontaneous union is unknown, and consequently any desired union requires open reduction and bone grafting. Many authors recommend performing the operation at the age of 3-5 years and using different fixation methods. We present our experience with three cases and literature review in an attempt to further elucidate the appropriate timing of the procedure and the fixation method...

BACKGROUND: Deficient osteogenic capacity of bone marrow stem cells plays a critical role in the pathophysiology of osteoporosis. Adipose-derived stem cells (ADSCs) have emerged as a promising source of skeletal progenitor cells. The capacity of ADSCs to undergo osteogenic differentiation and induce mineralized tissue formation may be beneficial in the treatment of osteoporosis. We question whether administration of autologous ADSCs into the proximal femur of osteoporotic rats will induce osteogenesis and enhance bone quality and strength...

Even though one of the surgical techniques most frequently used to correct external rotation deformity of the shoulder in brachial plexus patients is a humeral derotational osteotomy, few intraoperative parameters has yet been identified to determine the appropriate degree of rotation. We present in this technical note our initial experience using the main elbow flexion skin crease to quantify the correct rotation of the humerus in four young, male patients with upper-type brachial plexus injuries. All patients had a functional elbow and a stable shoulder, but also an external rotation deficit...

BACKGROUND: Revision of failed anatomic total shoulder arthroplasty or hemiarthroplasty is a challenging procedure. Restoring adequate soft tissue balance in the revision setting can be particularly problematic. When persistent posterior instability is encountered in the revision setting, options include changing component position or size, posterior capsular plication (PCP), or conversion to a reverse arthroplasty. The purpose of this study was to report the clinical and radiographic outcomes, complications, and reoperations of PCP performed in the setting of revision anatomic shoulder arthroplasty...
