Computational Metrics Can Provide Quantitative Values to Characterize Arthroscopic Field of View.

Purpose: The purpose of this study was to determine the inter-rater reliability of arthroscopic video quality, determine correlation between surgeon rating and computational image metrics, and facilitate a quantitative methodology for assessing video quality.

Methods: Five orthopaedic surgeons reviewed 60 clips from deidentified arthroscopic shoulder videos and rated each on a four-point Likert scale from poor to excellent view. The videos were randomized, and the process was completed a total of three times.

Risk factors for decreased range of motion and poor outcomes in open periarticular elbow fractures.

Introduction: The purpose of this study was to identify risk factors present at the time of injury that predict poor functional outcomes and heterotopic ossification (HO) in open periarticular elbow fractures.

Materials And Methods: We performed a retrospective review of 136 combat-related open elbow fractures from 2003 to 2010. Patient demographics, injury characteristics, treatment variables, and complications were recorded.

Known preoperative deep venous thrombosis and/or pulmonary embolus: to flap or not to flap the severely injured extremity?

Background: Warfare-related extremity injury associated with pelvic and long-bone fractures, massive soft-tissue injuries, and high Injury Severity Scores predispose patients to venous thromboembolic events, including deep vein thrombosis and/or pulmonary embolism. The success of flap reconstruction in this setting has not been well described.

Methods: A retrospective review of war-related extremity injuries requiring flap coverage from 2003 to 2012 was completed, and the incidence of venous thromboembolic events determined.

Heterotopic ossification resection after open periarticular combat-related elbow fractures.

A retrospective review was performed to evaluate the outcomes and complications following heterotopic ossification (HO) resection and lysis of adhesion procedures for posttraumatic contracture, after combat-related open elbow fractures. From 2004 to 2011, HO resection was performed on 30 blast-injured elbows at a mean 10 months after injury. Injuries included 8 (27%) Gustilo-Anderson type II fractures, 8 (27%) type III-A, 10 (33%) III-B, and 4 (13%) III-C.

Fibroma of the tendon sheath - a rare hand tumor.

Fibroma of the tendon sheath (FTS) is a rare, benign, soft tissue lesion. Clinically, FTS presents similarly to the more common giant cell tumor of the tendon sheath. It is distinguished histologically by the lack of giant cells, foamy histiocytes and synovial cells.

Light promotes regeneration and functional recovery and alters the immune response after spinal cord injury.

Background And Objectives: Photobiomodulation (PBM) has been proposed as a potential therapy for spinal cord injury (SCI). We aimed to demonstrate that 810 nm light can penetrate deep into the body and promote neuronal regeneration and functional recovery.

Study Design/materials And Methods: Adult rats underwent a T9 dorsal hemisection, followed by treatment with an 810 nm, 150 mW diode laser (dosage = 1,589 J/cm2).
