Anomalous Flexor Carpi Radialis Tendons Giving Rise to a Novel Surgical Technique in the Treatment of Thumb Carpometacarpal Joint Arthritis: A Case Report.

Introduction: Incidental discovery of anomalous muscles and anatomical variants within the forearm and wrist through surgical exposure and advanced imaging techniques is relatively common.

Case Report: The patient presented with pain and swelling in her hand that was refractory to rest and anti-inflammatory medications. Here, we describe the intraoperative discovery of an anatomical variant of the flexor carpi radialis (FCR), as well as an anomalous flexor carpi radialis brevis (FCRB) in a 58-year-old patient being treated for thumb carpometacarpal joint (CMCJ) arthritis.

The Effect of Extracorporeal Membrane Oxygenation in Patients With Multiple Orthopaedic Injuries.

Introduction: Extracorporeal membrane oxygenation (ECMO) plays a vital role in providing life support for patients with reversible cardiac or respiratory failure. Given the high rate of complications and difficulties associated with caring for ECMO patients, the goal of this study was to compare outcomes of orthopaedic surgery in polytrauma patients who received ECMO with similar patients who have not. This will help elucidate the timing and type of fixation that should be considered in patients on ECMO.

Optimization of the visco-elastic parameters describing the heel-region of a prosthesis.

Although compliance (visco-elasticity) of a prosthesis has the potential to affect clinically relevant aspects of a lower extremity amputee's gait, it is currently unknown what the compliant parameter values should be. Here, a simple dynamical model is used to approximate walking with a compliant prosthesis. An exhaustive search is used to identify the optimal compliant element parameter set in terms of the model's stability as measured by the reciprocal of the gait sensitivity norm (rGSN).
