Comparing Access to Engaging Hill-Sachs Lesions Between the Modified Posterior Deltoid Split Approach and Standard Deltopectoral Approach for Bone Grafting.

Background: Hill-Sachs lesions are common after shoulder instability, and treatment options vary but include remplissage or implantation of structural bone graft. Large Hill-Sachs lesions not addressed by remplissage are challenging to manage and may frequently require an open surgical approach for bone filling treatment options. The optimal approach to maximize visualization of the humeral head during these procedures remains unclear.

Effect of Posterior Malleolar Fixation on Syndesmotic Stability.

Background: Transsyndesmotic fixation with suture buttons (SBs), posterior malleolar fixation with screws, and anterior inferior tibiofibular ligament (AITFL) augmentation using suture tape (ST) have all been suggested as potential treatments in the setting of a posterior malleolar fracture (PMF). However, there is no consensus on the optimal treatment for PMFs.

Purpose: To determine which combination of (1) transsyndesmotic SBs, (2) posterior malleolar screws, and (3) AITFL augmentation using ST best restored native tibiofibular and ankle joint kinematics after 25% and 50% PMF.

Biomechanical Evaluation of 4 Suture Techniques for Hip Capsular Closure.

Background: The most reliable suture technique for capsular closure after a capsulotomy remains unknown.

Purpose: To determine which suture technique best restores native stability after a 5-cm interportal capsulotomy.

Study Design: Controlled laboratory study.

A new understanding of radiographic landmarks of the greater trochanter that indicate correct femoral rotation for measurement of femoral offset.

Objectives: To establish and validate a novel method for aligning femoral rotation to accurately measure femoral offset for preoperative templating and component sizing, and to identify the physical location of two radiographic lines utilized in the described method.

Materials And Methods: Cadaveric proximal femurs were skeletonized and mounted to a biaxial load frame. Two radiographic lines along the greater trochanter were identified fluoroscopically.

Brown Fat Promotes Muscle Growth During Regeneration.

Accumulation of adipose tissue around and within muscles is highly correlated with reduced strength, functional limitations, and poor rehabilitative outcomes. Given the intimate physical contact between these tissues, paracrine cross-talk is a likely mediator of this association. The recent discovery that muscle-associated adipose tissue exhibits features of beige fat has suggested that this cross-talk may be modifiable, as beige fat can be stimulated to assume features of brown fat.
