Interposition Dermal Matrix Xenografts: A Successful Alternative to Traditional Treatment of Massive Rotator Cuff Tears.

Background: Management of massive rotator cuff tears in shoulders without glenohumeral arthritis remains problematic for surgeons. Repairs of massive rotator cuff tears have failure rates of 20% to 94% at 1 to 2 years postoperatively as demonstrated with arthrography, ultrasound, and magnetic resonance imaging. Additionally, inconsistent outcomes have been reported with debridement alone of massive rotator cuff tears, and limitations have been seen with other current methods of operative intervention, including arthroplasty and tendon transfers.

Medicolegal aspects of sports medicine.

Legal issues in sports medicine are rapidly developing and establishing an important body of jurisprudence that defines the legal rights and duties of all those involved with protecting the health and safety of athletes. The law makes important distinctions between the relevant duty of care owed to high-school, college, and professional athletes because of the differing legal relationships that arise out of athletic participation at different levels of competition.

Dermal tissue allograft for the repair of massive irreparable rotator cuff tears.

Background: Massive irreparable rotator cuff tears in patients without advanced glenohumeral arthritis can pose a challenge to surgeons. Numerous management strategies have been utilized, and studies have shown varied results with regard to shoulder pain, range of motion, strength, and overall function.

Hypothesis: Patients undergoing repair of massive irreparable rotator cuff tears through a mini-open approach with the use of human dermal tissue matrix allograft would demonstrate an improvement in pain, range of motion, strength, and subjective functional outcomes.

Gastrointestinal infections in the traveling athlete.

Because athletes travel to competitions all over the world, sports medicine providers need to be able to diagnose and treat gastrointestinal infections. Traveler's diarrhea (TD) is by far the most common gastrointestinal illness. TD is a self-limited condition caused by bacteria, viruses, or parasites, and it can easily be treated.

Medicolegal issues in sports medicine.

This article reviews medicolegal issues in sports medicine. Nonmusculoskeletal medical conditions discussed include cardiac abnormalities, heat illness, and concussion in the athlete. Musculoskeletal injuries with the greatest potential for litigation, knee dislocation, and cervical spine trauma, are also reviewed.
