Multicenter StudyAdolescent clavicle nonunions: potential risk factors and surgical management.
Clavicle nonunions in adolescent patients are exceedingly rare. The purpose of this study was to evaluate a series of clavicle nonunions from a pediatric multicenter study group to assess potential risk factors and treatment outcomes. ⋯ Clavicle nonunions can occur in the adolescent population but are an uncommon clinical entity. The majority occur in male patients with displaced fractures, many of whom have sustained previous fractures of the same clavicle. High rates of union were achieved with plate fixation and the use of bone graft.

Tobacco use predicts a more difficult episode of care after anatomic total shoulder arthroplasty.
In the current health care environment, it is becoming increasingly important to recognize risks factors that may affect a patient's postoperative outcome. To determine the potential impact of tobacco as a risk factor, we evaluated postoperative pain, narcotic use, length of stay, reoperations, and complications in the global 90-day episode of care for patients undergoing anatomic total shoulder arthroplasty (TSA) who were current tobacco users, former users, or nonusers. ⋯ Although length of stay, complication rates, hospital readmissions, and reoperation rates were not significantly different, tobacco users reported increased postoperative pain and narcotic use in the global period after TSA. Former tobacco users were found to have a postoperative course similar to that of nonusers, suggesting that discontinuation of tobacco use can improve a patient's episode of care performance after TSA.

Randomized Controlled TrialRadiographic and clinical comparison of pegged and keeled glenoid components using modern cementing techniques: midterm results of a prospective randomized study.
Glenoid component loosening remains a significant issue after anatomic shoulder arthroplasty. Pegged glenoid components have shown better lucency rates than keeled components in the short term; however, midterm to long-term results have not fully been determined. We previously reported early outcomes of the current randomized controlled group of patients, with higher glenoid lucency rates in those with a keeled glenoid. The purpose of this study was to evaluate the radiographic and clinical outcomes of these components at minimum 5-year follow-up. ⋯ At an average 7.9-year follow-up, non-ingrowth, all-polyethylene pegged glenoid implants are equivalent to keeled implants with respect to radiolucency, clinical outcomes, and need for revision surgery.

Surgical anatomy of the radial nerve in the deltopectoral approach for revision shoulder arthroplasty and periprosthetic fracture fixation: a cadaveric study.
Radial nerve injury is a rare but clinically significant complication of revision shoulder arthroplasty and fixation of native and periprosthetic proximal humeral fractures. Understanding of the anatomic relationship between the radial nerve as it enters the humeral spiral groove and anterior shoulder landmarks in a deltopectoral approach is necessary to avoid iatrogenic radial nerve injury. ⋯ The risk of iatrogenic injury to the radial nerve at the spiral groove may be minimized through proper identification and protection or avoidance of circumferential fixation. However, if encircling fixation with cerclage cables is necessary, instrumentation proximal to the inferior edge of the latissimus dorsi insertion may reduce the risk of radial nerve injury.

Angled BIO-RSA (bony-increased offset-reverse shoulder arthroplasty): a solution for the management of glenoid bone loss and erosion.
Glenoid deficiency and erosion (excessive retroversion/inclination) must be corrected in reverse shoulder arthroplasty (RSA) to avoid prosthetic notching or instability and to maximize function, range of motion, and prosthesis longevity. This study reports the results of RSA with an angled, autologous glenoid graft harvested from the humerus (angled BIO-RSA). ⋯ Angled BIO-RSA predictably corrects glenoid deficiency, including severe (>25°) multiplanar deformity. Graft incorporation is predictable. Advantages of using an autograftharvested in situ include bone stock augmentation, lateralization, low donor-site morbidity, low relative cost, and flexibility needed to simultaneously correct posterior and superior glenoid defects.
