Prognostic Factors Leading to Good or Poor Outcomes Based on Functional and Radiological Findings After a Rotator Cuff Retear.

Background: A retear after rotator cuff repair is a common problem; however, there is little information related to the prognosis after a retear. In addition, some patients with retears have satisfactory outcomes, which raises the question of whether a retear leads to a poor prognosis.

Purpose: To identify radiological factors that influence the prognosis after a retear.

Patch augmentation does not provide better clinical outcomes than arthroscopic rotator cuff repair for large to massive rotator cuff tears.

Purpose: Patch augmentation for large and massive rotator cuff tears (LMRCTs) has been suggested as a repair strategy that can mechanically reinforce tendons and biologically enhance healing potential. The purpose of this study was to determine whether patients who underwent patch augmentation would have lower rates of retears and superior functional outcomes.

Methods: Patients who underwent arthroscopic rotator cuff repair (ARCR) with patch augmentation (group A) were matched by age, sex, degree of retraction, and supraspinatus muscle occupation ratio to those treated with ARCR without using a patch (group B) with a minimum follow-up of 24 months.

Low serum vitamin B levels are associated with degenerative rotator cuff tear.

Background: Vitamin B (Vit B) deficiency results in elevated homocysteine levels and interference with collagen cross-linking, which may affect tendon integrity. The purpose of this study was to investigate whether serum Vit B levels were correlated with degenerative rotator cuff (RC) tear.

Methods: Eighty-seven consecutive patients with or without degenerative RC tear were enrolled as study participants.

Muscle mass measurements in hip fracture patients and control general population depending on dual-energy X-ray absorptiometry device used: The General Electric Lunar and Hologic systems.

Objectives: The prevalence of sarcopenia, an independent risk factor for fragility fractures, is high in geriatric hip fracture patients. We aim to compare patients with hip fractures to the general population using different dual-energy X-ray absorptiometry (DXA) devices - General Electric (GE) Lunar and Hologic.

Methods: We retrospectively reviewed data of patients diagnosed with osteoporotic hip fractures.

Kienböck's disease with non-negative ulnar variance : Treatment with combined radial wedge and shortening osteotomy.

Purpose: There are only few studies that focused on Kienböck's disease with non-negative ulnar variance, even though many surgical procedures have been introduced. A combined radial wedge and shortening osteotomy was carried out for Kienböck's disease with non-negative ulnar variance. The purpose of this article is to report the results of this procedure by analyzing the clinical and radiological data.

Comparison of Bone Mineral Density and Appendicular Lean Body Mass between Osteoporotic Distal Radius Fracture and Degenerative Rotator Cuff Tear in Women Patients.

Background: Authors assessed lean body mass (fat free tissue), upper and lower, and bone mineral density (BMD) in patients of osteoporotic bone distal radius fracture (DRF) and degenerative rotator cuff tear (RCT) patients of shoulder. We predict inferior muscle mass and osteoporosis are more frequent in DRF group than RCT group.

Methods: Between January 2016 and June 2017, overall 38 of DRF and 30 of RCT were eligible for this retrospective comparison study after excluding of patients with compounding factors.
