BACKGROUND Very little comparative information is available regarding the demographic and morphological characteristics of asymptomatic and symptomatic rotator cuff tears. This information is important to provide insight into the natural history of rotator cuff disease and to identify which factors may be important in the development of pain. The purpose of(More)
The elastic fiber is known to be an important component of skin, lung, and vasculature. Much less is known about the distribution of elastin and elastic fiber-related proteins in connective tissues, yet genetic defects of elastic fiber constituents can lead to deficiencies in these tissues. For the first time, we determine the distribution of elastin,(More)
The vascular anatomy of the flexor digitorum profundus (FDP) tendon insertion is described by using a vascular injection and modified Spalteholtz tissue clearing protocol in 36 human cadaver digits. A consistent dense palmar and dorsal vascular supply to the tendon at its insertion into the distal phalanx was observed based on sources from both the distal(More)
Little is known about the localized changes in bone mass that occur following tendon or ligament injury. Interruption of normal load transfer at the insertion site will presumably lead to a localized loss of bone, although few data exist to support this claim. To test this hypothesis, we transected the canine flexor digitorum profundus (FDP) tendon from its(More)
BACKGROUND Floating elbow fractures in adults are rare and complex injuries with unpredictable outcomes. The present study was designed to assess our experience, analyze possible compilations and illustrate prognostic factors of the final outcome. METHODS Between 2002 and 2009, 19 patients with floating elbow fractures were treated in our department (mean(More)
PURPOSE There have been few prospective studies evaluating the results of nonsurgical treatment of a well-defined patient cohort with symptomatic basal joint osteoarthritis of the thumb. This prospective study uses a validated outcome instrument to examine the effectiveness of a single steroid injection and 3 weeks of splinting in patients with(More)
The long head of the biceps tendon (LHBT) is an anatomic structure commonly involved in painful shoulder conditions as a result of trauma, degeneration, or overuse. Recent studies have pointed out the close correlation between LHBT lesions and rotator cuff (RCT) tears. Clinicians need to take into account the importance of the LHBT in the presence of other(More)
PURPOSE Recent in vivo canine studies have shown incomplete restoration of the flexor digitorum profundus (FDP) insertion site after transection and repair to the cortical surface of the distal phalanx. Previous biomechanical analyses of tendon to bone surface repair have suggested that repair site gap formation of greater than 3 mm occurs frequently under(More)
Insertion site injuries of the flexor digitorum profundus (FDP) tendon often present for delayed treatment. Apart from gross observations made at the time of surgery, the changes that occur in the flexor tendon stump during the interval from injury to repair are unknown. These changes may include tendon softening and loss of viability, which may contribute(More)
Tibial eminence avulsion fractures are rare injuries occurring mainly in adolescents and young adults. When necessary, regardless of patient age, anatomic reduction and stable internal fixation are mandatory for fracture healing and accurate restoration of normal knee biomechanics. Various arthroscopically assisted fixation methods with sutures, anchors,(More)
