Controlled active mobilization following surgical repair of the avulsed radial attachment of the biceps brachii muscle: a case report.

Traumatic disruption of the radial attachment of the biceps brachii muscle may require surgical reattachment to obtain and maintain optimum anatomical relationships and ensure return to full, unlimited activity, particularly in the young athletic patient with high muscle performance demands. Postoperative evaluation and care following surgical reattachment of the avulsed radial tendon of the biceps brachii muscle has not previously been reported in the rehabilitation literature. The purpose of this case study is to report successful treatment of a gymnast using static splinting, controlled active mobilization of the elbow, and strengthening exercises following surgical reattachment of the avulsed radial attachment of the biceps brachii muscle.

Rethinking primate locomotion: what can we learn from development?

Contemporary understanding about primate locomotion has largely been conditioned by studies of adults. It is as yet uncertain how locomotor behavior emerges during ontogeny or the life history of an individual (Gould, 1977). This article explores the manner in which changes in body size, proportions, and composition that occur during growth can potentially influence motor output, substrate selection, and structural design. A central theme explicit in this article is that growth provides an important source of morphological change, both regulating and generating motor behavior and substrate use. It is emphasized that morphology, behavior, and substrate use are integrated and should be investigated in tandem.

Soft-tissue bone interface: how do attachments of muscles, tendons, and ligaments change during growth? A light microscopic study.

This study addressed the problem of how soft structures maintain approximately the same relative positional relationships during long bone growth. Attachments of the popliteus muscle, semitendinosus tendon, medial collateral knee ligament, and extensor retinaculum were examined histologically in rabbits, aged 2-60 days, to determine the manner in which soft structures attached to long bones during growth. Soft structures inserted principally into fibrous periosteum or perichondrium in the age range studied. However, an extensive collagen fiber framework within the cellular periosteum and perichondrium, present by at least 2 days of age, linked the fibrous periosteum or perichondrium to subjacent bone or cartilage. Maturation of soft tissue-bone interfaces was viewed from two related perspectives. The first stressed temporal patterning of cartilage and bone differentiation. The second emphasized incorporation of attachments of soft structures into bone and cartilage matrices during growth and remodeling. Differentiation and remodeling of bone and cartilage varied not only with age, but also between regions of attachment of single muscles and ligaments. Insertion regions were characterized by the presence of coarse-fibered periosteal bone and chondroid bone, both morphologically intermediate between fibrocartilage and lamellar bone. These results provide evidence that periosteal attachments, characterizing the soft-tissue bone interface, are a necessary structural prerequisite for compensatory movement and invariance of the relative positions of muscles, tendons, and ligaments during long bone growth.

Fractures of the distal radius: what are the expectations of therapy? A two-year retrospective study.

This retrospective study addressed two basic questions important to hand therapists: what are the expectations of therapy vis-a-vis range of motion and strength among patients with distal radius fractures, and do patients treated by different therapists within a center experience substantially similar or dissimilar outcomes? Differences between patient groups were tested using ANOVA, and changes in performance were tested using the Student's t-test; significant differences between patient groups treated by different therapists were lacking and patients demonstrated significant changes in active motion and strength. Data were used to derive regression equations that yielded good estimates of active motion at discharge from therapy. Patients were treated an average of ten times; at discharge, they demonstrated active wrist and forearm motion compatible with the performance of activities of daily living.

Management of a metacarpophalangeal joint fracture using a dynamic traction splint and early motion.

Dynamic traction and early motion have been used by hand therapists to treat proximal interphalangeal joint fractures with good results. However, metacarpophalangeal joint fractures have been neglected, perhaps because of their relative infrequency. The purpose of this case study is to report the authors' experience using dynamic traction in conjunction with early motion to treat a construction worker who fell from scaffolding and sustained a complex fracture of the left smallfinger proximal phalanx with involvement of the metacarpophalangeal joint. Range of motion of the patient's left small finger at discharge from therapy, approximately 22 weeks postoperatively, was as follows: metacarpophalangeal joint, hyperextension/65 (85 degrees passive flexion); proximal interphalangeal joint, 20/80 (5/90 passively); and distal interphalangeal joint, 0/50 (65 degrees passive flexion). The patient made a successful return to full-time construction work. The results of this case appear to support consideration of the use of dynamic traction and early motion for management of selected metacarpophalangeal joint fractures.
