Clinical and radiological outcomes between superior capsule reconstruction using allografts or xenografts: a 2-year retrospective comparison study.

Background: Treating symptomatic, massive, irreparable rotator cuff tears remains challenging and controversial. Superior capsule reconstruction (SCR) using the tensor fascia lata has shown promising clinical results; however, due to donor site morbidity, interest in SCR using other grafts has increased. Yet, no studies have compared allografts with xenografts.

Latarjet procedure without capsular repair produces favorable clinical results and avoids limitation in external rotation.

Purpose: This study aimed at analyzing the range of motion (ROM) and other clinical outcomes in patients with > 20% glenoid bone loss who underwent the Latarjet procedure with or without anterior capsule repair.

Methods: This retrospective study included 47 patients with > 20% glenoid bone loss who underwent the classic Latarjet procedure from 2016 to 2021. Of these, 25 did not undergo capsular repair (no-capsular-repair group; group I) whereas 22 patients did (capsular-repair group; group II).

Biomechanical study of Proximal humeral fracture fixation: Locking plate with medial support screw vs. locking plate with intramedullary fibular graft.

Background: The purpose of this study was to evaluate the biomechanical properties of two different fixation constructs in varus collapse proximal humerus fracture, locking plate with medial support screw and locking plate with intramedullary fibular graft.

Methods: We used 8 pairs of undamaged fresh-frozen humen cadaveric humeri and fibula from patients ranging in age from 62 to 81 years. We simulated a proximal humerus fracture with medial comminution using wedge shaped osteotomy.

Arthroscopic Superior Capsular Reconstruction With Biceps Autograft: Snake Technique.

Many options have been developed to treat irreparable massive cuff tears. Superior capsular reconstruction has been reported as one of the treatment options for relatively young patients with irreparable massive cuff tear. However, this original technique has a disadvantage of requiring a tensor facia lata autograft.

Three-dimensional in vivo scapular kinematics and scapulohumeral rhythm: a comparison between active and passive motion.

Background: The aim of this study was to compare the scapular kinematics and scapulohumeral rhythm of healthy participants during arm elevation and lowering and to find the difference between active motion and passive motion of the shoulder.

Methods: The study examined the shoulders of 10 healthy men (mean age, 23.5 years; age range, 22-28 years).

Comparative efficacy and safety of gemigliptin versus linagliptin in type 2 diabetes patients with renal impairment: A 40-week extension of the GUARD randomized study.

Aims: The long-term safety and efficacy of gemigliptin was evaluated in the present extension study after a 12-week study during a 40-week follow-up period.

Methods: The main study was a randomized, placebo-controlled, double-blinded, phase IIIb study in which 50 mg of gemigliptin (N = 66) or placebo (N = 66) was administered to patients with type 2 diabetes mellitus (T2DM) and moderate or severe renal impairment over a 12-week period. Patients with a glycated haemoglobin (HbA1c) level of 7% to 11% and an estimated glomerular filtration rate (eGFR) of 15 to 59 mL/min/1.

Effects of short malunion of the clavicle on in vivo scapular kinematics.

Background: Short malunion of the clavicle after fracture can change scapular kinematics and alter clinical outcome. However, the effects of malunion on kinematics and outcomes remains poorly understood because there have been no in vivo studies measuring changes during active motion with malunion. This study aimed to measure and to compare in vivo 3-dimensional (3D) scapular kinematics between normal shoulders and shoulders with short malunion using 3D-2-dimensional model image registration techniques.

Comparison of 2 Different Exercise Approaches: Tai Chi Versus Otago, in Community-Dwelling Older Women.

Background And Purpose: Regular exercise can delay age-related risk factors and can maintain or improve physical health and activity in older adults leading to a decrease in fall risk. The purpose of this study was to compare 2 different interventions for fall prevention, tai chi (TC) and Otago, by examining lower extremity strength, balance, and spatiotemporal gait parameters in community-dwelling older women.

Methods: We performed a randomized trial in which subjects were assigned to 1 of 2 groups: the TC group (n = 21; age, 72.
