Atypical presentation of Parsonage-Turner syndrome confounded by surgical rotator cuff injury.

Parsonage-Turner syndrome (PTS) is a rare neuropathy that commonly presents as unexpected severe shoulder and arm pain that eventually subsides while weakness or paralysis ensues. During exceptions to this classic presentation, confirming PTS can be challenging. Alternative causes of upper extremity pain may confound the diagnostic algorithm.

Inadequate Helmet Fit Increases Concussion Severity in American High School Football Players.

Background: There is limited information on the relationship between football helmet fit and concussion severity.

Hypothesis: Poor helmet fit may predispose football players to a more severe concussion.

Study Design: Descriptive epidemiology study.

Association between GRIN2A promoter polymorphism and recovery from concussion.

Objective: To determine genetic variability within the N-methyl-D-aspartate receptor 2A sub-unit (GRIN2A) gene promoter and its association with concussion recovery time. The hypothesis tested was that there would be a difference in allele and/or genotype distribution between two groups of athletes with normal and prolonged recovery.

Methods: DNA was extracted from saliva collected from a total of 87 athletes with a physician-diagnosed concussion.

Enoxaparin and Warfarin for Venous Thromboembolism Prophylaxis in Total Hip Arthroplasty: To Bridge or Not to Bridge?

Anticoagulation bridges consisting of subcutaneous enoxaparin combined with oral-dosed warfarin are commonly used in orthopedic procedures as chemoprophylaxis against thromboembolic disease. For some patients, these bridges result in complications. One hundred twenty-one patients were evaluated after primary total hip arthroplasty (THA) between 2008 and 2009.

Hypertensive patients show delayed wound healing following total hip arthroplasty.

Background: Prolonged wound-discharge following total hip arthroplasty (THA) is associated with an increased risk of infection. However, the potential role of hypertension in prolonging the duration of wound healing in this population has not yet been investigated. The aim of the present study was to compare healing in this population that has not yet been investigated.
