Comparison of Scapular Mechanics After Activity With and Without a Targeted Compression Garment.

Muscle fatigue can result in scapular dyskinesis, which has been implicated in impingement, labral injury, and rotator cuff injury. This study evaluated the ability of a compression shirt to maintain scapular alignment after fatiguing of periscapular musculature. Subjects' scapular movements were monitored before and after a periscapular muscle- fatiguing exercise program.

Biomechanics of an Expandable Lumbar Interbody Fusion Cage Deployed Through Transforaminal Approach.

Background: A novel expandable lumbar interbody fusion cage has been developed which allows for a broad endplate footprint similar to an anterior lumbar interbody fusion; however, it is deployed from a minimally invasive transforaminal unilateral approach. The perceived benefit is a stable circumferential fusion from a single approach that maintains the anterior tension band of the anterior longitudinal ligament. The purpose of this biomechanics laboratory study was to evaluate the biomechanical stability of an expandable lumbar interbody cage inserted using a transforaminal approach and deployed in situ compared to a traditional lumbar interbody cage inserted using an anterior approach (control device).

Biomechanics of an Expandable Lumbar Interbody Fusion Cage Deployed Through Transforaminal Approach.

Introduction: A novel expandable lumbar interbody fusion cage has been developed which allows for a broad endplate footprint similar to an anterior lumbar interbody fusion (ALIF); however, it is deployed from a minimally invasive transforaminal unilateral approach. The perceived benefit is a stable circumferential fusion from a single approach that maintains the anterior tension band of the anterior longitudinal ligament.The purpose of this biomechanics laboratory study was to evaluate the biomechanical stability of an expandable lumbar interbody cage inserted using a transforaminal approach and deployed in situ compared to a traditional lumbar interbody cage inserted using an anterior approach (control device).

Ertl below-knee amputation using a vascularized fibular strut in a nontrauma elderly population: a case series.

Background: Tibiofibular bone bridging (Ertl) during a below-knee amputation (BKA) is used to create a stable bony platform, granting the patient improved rotary stability, higher end bearing potential, and ultimately, more functional ambulatory ability. However, limited data are available in the literature on actual patient outcomes, despite numerous reports of the technique. The purpose of this study was to report our experience with distal tibiofibular bone bridging using a vascularized fibular bone graft in an elderly nontrauma population.

Outcomes after 294 transtibial amputations with the posterior myocutaneous flap.

The transtibial amputation is a common operation for which there is little agreement regarding which technique provides the most reliable and resilient outcomes. We performed a retrospective chart review of all transtibial amputations performed by a single surgeon between 2004 and 2011 using the posterior myocutaneous flap with triceps surae myodesis technique. A stepwise logistic regression analysis was performed to evaluate the association between independent variables and dependent outcome variables.
