Acromioclavicular joint injuries are among the most common shoulder girdle injuries in athletes and most commonly result from a direct force to the acromion with the arm in an adducted position. Acromioclavicular joint injuries often present with associated injuries to the glenohumeral joint, including an increased incidence of superior labrum anterior posterior (SLAP) tears that may warrant further evaluation and treatment. Anteroposterior stability of the acromioclavicular joint is conferred by the capsule and acromioclavicular ligaments, of which the posterior and superior ligaments are the strongest. ⋯ While a return to the previous level of functional activity with nonsurgical treatment has been documented in a number of case series, surgical reduction and coracoclavicular ligament reconstruction has been associated with a favorable outcome and can be considered in patients who place high functional demands on their shoulders or in athletes who participate in overhead sports. Surgical management is indicated for high-grade (≥type IV) acromioclavicular joint injuries to achieve anatomic reduction of the acromioclavicular joint, reconstruction of the coracoclavicular ligaments, and repair of the deltotrapezial fascia. Outcomes after surgical reconstruction of the coracoclavicular ligaments have been satisfactory with regard to achieving pain relief and return to functional activities, but further improvements in the biomechanical strength of these constructs are necessary to avoid loss of reduction and creep with cyclic loading.

Factors associated with longer length of hospital stay after primary elective ankle surgery for end-stage ankle arthritis.
Longer length of stay in the hospital after elective surgery results in increased use of health-care resources and higher costs. Improved perioperative care permits many foot and ankle surgical procedures to be performed as day surgery. This study determined perioperative factors associated with a longer length of stay after elective total ankle replacement or ankle arthrodesis. ⋯ The patients who are identified with a higher risk of a longer length of stay may warrant better education and more focused perioperative care when designing care pathways and allocating health-care resources.

Gain in spinal height from surgical correction of idiopathic scoliosis.
A relationship between spinal distraction and correction of the curvature of scoliosis has long been recognized. While attempts have been made to define the height that is lost with progression of scoliosis, much less information is available to define the height that is gained as a result of surgical correction of the curve and to quantify additional spinal growth after spine fusion. ⋯ Patients undergoing surgical correction of idiopathic scoliosis gain substantial height related to the magnitude of surgical correction, the number of levels fused, and preoperative stature. Continued spine growth by two years after surgery is associated with shorter fusions, skeletal immaturity, young age, and male sex. Height gain is a quantifiable outcome of the surgical correction of scoliosis.

One-stage exchange arthroplasty for chronic periprosthetic hip infection: results of a large prospective cohort study.
Exchange arthroplasty of one or two stages is required for the treatment of chronic periprosthetic joint infections. Two-stage exchange is costly and has high morbidity with limited patient mobility between procedures. One-stage exchange has been promoted by several European teams as the preferred alternative. The aim of this study was to prospectively analyze the outcome of patients with a periprosthetic hip infection treated with one-stage exchange arthroplasty. ⋯ One-stage exchange arthroplasty is an effective surgical procedure in patients with periprosthetic hip infection who have good bone quality. Precise identification of the microorganism(s) and prolonged administration of appropriate intravenous antibiotic therapy are key factors for successful treatment.

Intrawound vancomycin powder eradicates surgical wound contamination: an in vivo rabbit study.
Surgical site infection remains a complication of spine surgery despite routine use of prophylactic antibiotics. Retrospective clinical studies of intrawound vancomycin use have documented a decreased prevalence of surgical site infection after spine surgery. The purpose of the present study was to assess the efficacy of intrawound vancomycin powder in terms of eradicating a known bacterial surgical site contamination in a rabbit spine surgery model. ⋯ This animal study supports the findings in prior clinical reports that intrawound vancomycin powder helps reduce the risk of surgical site infections.
