An Evaluation of the Bacterial Adherence to Casting Materials.

Introduction:  The purpose of this study was to evaluate bacterial adherence to common casting materials including plaster of Paris (plaster), fiberglass, three-dimensional (3D) printed plastic, and silicone-coated 3D printed plastic.

Methods: The minimal inhibitory concentration of a phosphate-free detergent (Palmolive) needed to achieve total bacterial kill off was determined. 3D printed polylactic acid plastic samples were coated with silicone.

The Accuracy of 3D Printed Carpal Bones Generated from Cadaveric Specimens.

Background: Computer assisted three-dimensional (3D) printing of anatomic models using advanced imaging has wide applications within orthopaedics. The purpose of this study is to evaluate the 3D printing accuracy of carpal bones.

Methods: Seven cadaveric wrists underwent CT scanning, after which select carpal bones (scaphoid, capitate, lunate, and trapezium) were dissected in toto.

Risk of Infection in Trigger Finger Release Surgery Following Corticosteroid Injection.

Purpose: To determine the risk for infection in trigger finger release surgery after preoperative corticosteroid injection.

Methods: We retrospectively evaluated all patients undergoing trigger finger release by 16 surgeons over a 2-year period. Data collected included demographic information, medical comorbidities, trigger finger(s) operated on, presence of a prior corticosteroid injection, date of most recent corticosteroid injection, postoperative signs of infection, and need for surgery owing to deep infection.

Union Rates and Complications After Thumb Metacarpophalangeal Fusion.

Fusion of the thumb metacarpophalangeal joint (MPJ) can be performed using tension band wiring (TBW) or plate and screw (PS) fixation. This study evaluated results and complications using these techniques. A retrospective review of patients who underwent thumb MPJ fusion at our institution from 2010 to 2016 was performed.

Arterial Injury in the Upper Extremity: Evaluation, Strategies, and Anticoagulation Management.

Trauma to the upper extremity can present with an associated arterial injury. After patient stabilization, thorough assessment with physical examination and various imaging modalities allows accurate diagnosis of the specific arterial injury. After diagnosis, efficient treatment is necessary to allow limb salvage.
