Eighty-one patients with symptomatic osteoarthritis of the thumb took part in a blinded, controlled study to assess the effectiveness of 0.9 mw continuous wave HeNe laser treatment. The subjects were randomly placed in either a control group or a treatment group. In each group the carpometacarpal (CMC), metacarpophalangeal (MCP), and interphalangeal (IP)(More)
CONTEXT Dynamic shoulder motion can be captured using video capture systems, but reliability has not yet been established. OBJECTIVE To compare the reliability of 2 systems in measuring dynamic shoulder kinematics during forward-elevation movements and to determine differences in these kinematics between healthy and injured subjects. DESIGN Reliability(More)
Historically, the surgical treatment of bicipital pathology has been a variety of tenodesis techniques. The purpose of this study is to report the results of simple biceps tenotomy for the treatment of bicipital pathology. Thirty shoulders in 30 consecutive patients who had a simple arthroscopic biceps tendon release were reviewed. Data was collected(More)
We investigated the role of fatigue in muscle strain injuries using the extensor digitorum longus muscles of 48 rabbits. The muscles of the rabbits were fatigued by 25% or 50% then stretched to failure and compared with the contralateral controls. Three rates of stretch were used. The force to muscle failure was reduced in the fatigued leg in all groups(More)
STUDY DESIGN Repeated-measures design comparing 7 static weight-bearing shoulder exercises. OBJECTIVE The purpose of this study was to determine the demand on shoulder musculature during weight-bearing exercises and the relationship between increasing weight-bearing posture and shoulder muscle activation. BACKGROUND Weight-bearing shoulder exercises are(More)
The purpose of this study was to document range-of-motion differences and radiographic changes in the dominant shoulder of skeletally immature throwers and to determine how pain associated with throwing may relate to these changes. Seventy-nine male youth baseball players (aged 8-15 years) completed a questionnaire, a shoulder examination, and a series of(More)
Nine athletes (seven football offensive linemen, one defensive lineman, and one lacrosse player) were found at arthroscopy to have posterior labral detachment from the glenoid. In our series, this lesion is specific to contact athletes who engage their opponents with arms in front of the body. All patients had pain with bench pressing and while(More)
BACKGROUND In patients suffering from an anterior cruciate ligament injury, the incidence and location of bone bruises are well documented. This study reports data regarding bone bruises after acute posterior cruciate ligament injury. HYPOTHESIS Bone bruises associated with posterior cruciate ligament injury are common, and their location differs from(More)
BACKGROUND Distal rupture of the triceps tendon is a rare injury, and treatment guidelines are not well established. HYPOTHESIS Football players with triceps tendon ruptures will be able to return to their sport with minimal functional deficits. STUDY DESIGN Uncontrolled retrospective review. METHODS Twenty-one partial and complete ruptures of the(More)
This study examines if electromyographic (EMG) amplitude differences exist between patients with shoulder instability and healthy controls performing scaption, prone horizontal abduction, prone external rotation, and push-up plus shoulder rehabilitation exercises. Thirty nine subjects were categorized by a single orthopedic surgeon as having(More)
