OBJECTIVES Compartment syndrome is a devastating complication of tibial fractures. The purpose of this study was to investigate the rate of clinically determined compartment syndrome requiring surgical intervention in tibial fractures by anatomical region and to identify the associated patient and injury factors. DESIGN Retrospective cohort. SETTING(More)
Administration of intra-articular medications, including corticosteroids and analgesics, is common clinical practice for knee pathology and dysfunction. Non-steroidal anti-inflammatory drugs (NSAIDs) are another category of medication commonly prescribed for their analgesic and anti-inflammatory properties. Recent studies demonstrated the efficacy of(More)
As the largest and most powerful rotator cuff muscle, the subscapularis plays a critical role in proper shoulder function. The diagnosis of subscapularis tears is made based on history and physical examination and confirmed with imaging studies. Historically, subscapularis tears have been addressed in an open fashion. Recent literature has demonstrated(More)
High cholesterol represents a significant healthcare problem. Clinical studies have linked hypercholesterolemia to Achilles tendon xanthomas and rotator cuff tears, and research in other systems indicates detrimental effects of high cholesterol; however, understanding of its impact on tendon properties and healing is limited. We hypothesized that tendons(More)
Hematoma blocks with lidocaine are routinely utilized in the Emergency Department to allow reduction of Colles' fractures. Lidocaine toxicity is a potential complication of this procedure. We present a case report of a patient who developed acute mental status changes and generalized seizure immediately following administration of lidocaine during a(More)
BACKGROUND Surgical repairs of torn rotator cuff tendons frequently fail. Immobilization has been shown to improve tissue mechanical properties in an animal model of rotator cuff repair, and passive motion has been shown to improve joint mechanics in animal models of flexor tendon repair. Our objective was to determine if daily passive motion would improve(More)
BACKGROUND a rat model of supraspinatus overuse has suggested mechanisms governing tendon degeneration; however, delineating which changes are pathologic or simply physiologic adaptations to increased loading remains a question. The objective of this study was to develop and characterize a rat exercise model that induces systemic and local shoulder(More)
BACKGROUND Rotator cuff tears are common shoulder problems whose propagation is difficult to predict because of the structural and mechanical inhomogeneity of the supraspinatus tendon. We have previously shown that the supraspinatus and infraspinatus tendons interact mechanically when the supraspinatus tendon is intact or exhibits a full-thickness tear, so(More)
BACKGROUND More elderly patients are becoming candidates for total shoulder arthroplasty with an increase in frequency of the procedure paralleling the rise in other total joint arthroplasties. Controversy still exists, however, regarding the perioperative morbidity of total joint arthroplasty in elderly patients, particularly those 80 years of age and(More)
Shoulder tendon injuries are frequently seen in the presence of abnormal scapular motion, termed scapular dyskinesis. The cause and effect relationship between scapular dyskinesis and shoulder injury has not been directly defined. We developed and used an animal model to examine the initiation and progression of pathological changes in the rotator cuff and(More)
