Related Articles Clinical outcomes of hemiarthroplasty and biological resurfacing in patients aged younger than 50 years. J Shoulder Elbow Surg. 2013 Jun 21; Authors: Hammond LJ, Lin EC, Harwood DP, Juhan TW, Gochanour E, Klosterman EL, Cole BJ, Nicholson GP, Verma NN, Romeo AA Abstract BACKGROUND: Total shoulder arthroplasty as a treatment for glenohumeral degenerative joint disease is well accepted but has been less predictable with regard to outcomes and durability in a younger aged population, typically aged younger than 50 years. This younger population has a greater potential for glenoid component loosening. This has led surgeons to perform hemiarthroplasty or hemiarthroplasty with biological resurfacing of the glenoid in an effort to avoid the potential problems with a polyethylene glenoid and obtain durable and acceptable results for these patients. METHODS: The study included 44 patients, with 23 undergoing hemiarthroplasty alone and 21 undergoing hemiarthroplasty with biological resurfacing of the glenoid. All patients were aged younger than 50 years. Preoperative diagnoses, comorbidities, demographics, and range of motion were collected. Preoperative and postoperative radiographs were obtained. Preoperative and postoperative objective scoring measures (Single Assessment Numeric Evaluation, American Shoulder and Elbow Surgeons score, visual analog scale, Simple Shoulder Test, Constant-Murley) were used.

Related Articles Effectiveness of bracing in the treatment of nonosseous restriction of elbow mobility: a systematic review and meta-analysis of 13 studies. J Shoulder Elbow Surg. 2013 Aug;22(8):1146-52 Authors: Müller AM, Sadoghi P, Lucas R, Audige L, Delaney R, Klein M, Valderrabano V, Vavken P Abstract BACKGROUND: Restriction of elbow mobility is a very frequent complaint after trauma or surgery. The objective of this study was to assess and compare the effectiveness of dynamic, static, or static-progressive bracing in patients with elbow stiffness of traumatic or postoperative origin and without evidence of ossification. For the purpose of this study, effectiveness was measured as the increase in total range of motion, as well as extension and flexion. MATERIALS AND METHODS: We performed a systematic search of the keywords "elbow AND (stiffness OR stiff) AND (brace OR splint OR conservative)" in the online databases PubMed, EMBASE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Library. We included all clinical studies using dynamic or static bracing in patients with elbow stiffness. Eligible outcomes were changes in total range of motion, flexion, and extension; sustainability of results; and complications.

Related Articles Surgical treatment of elbow stiffness caused by post-traumatic heterotopic ossification. J Shoulder Elbow Surg. 2013 Aug;22(8):1128-34 Authors: Koh KH, Lim TK, Lee HI, Park MJ Abstract BACKGROUND: Heterotopic ossification (HO) is considered as a common extrinsic cause of elbow stiffness. The purpose of this study was to show the results of surgical treatment for post-traumatic elbow stiffness caused by HO in a large, consecutive series of patients in a single unit. METHODS: We retrospectively reviewed 77 surgically treated patients with post-traumatic elbow stiffness caused by HO. Final motion arc and Mayo Elbow Performance Index (MEPI) were assessed as final results. Univariable and multivariable analyses were done to determine which factors had an effect on the final motion arc.

Related Articles Age-related changes affect rat rotator cuff muscle function. J Shoulder Elbow Surg. 2013 Jun 20; Authors: Plate JF, Pace LA, Seyler TM, Moreno RJ, Smith TL, Tuohy CJ, Mannava S Abstract BACKGROUND: The influence of age on rotator cuff function and muscle structure remains poorly understood. We hypothesize that normal aging influences rotator cuff function, muscle structure, and regulatory protein expression in an established rat model of aging. METHODS: Seventeen rats were obtained from the National Institute on Aging. The supraspinatus muscles in 11 middle-aged (12 months old) and 6 old (28 months old) rats were studied for age-related changes in rotator cuff neuromuscular function by in vivo muscle force testing and electromyography (EMG). Changes in muscle structure and molecular changes were assessed with quantitative immunohistochemistry for myogenic determination factor 1 (MyoD) and myogenic factor 5 (Myf5) expression.
