We treated fifty-one cases of fracture of the shaft of the humerus with a functional method of treatment consisting of a plastic sleeve, individually molded or prefabricated. It maintained good alignment of the fragments and permitted rapid and uninterrupted osteogenesis. The early introduction of functional activity to the entire extremity appears to(More)
BACKGROUND Nonoperatively treated fractures of the humeral diaphysis have a high rate of union with good functional results. However, there are clinical situations in which operative treatment is more appropriate, and, though interest in plate osteosynthesis has decreased, intramedullary nailing has gained popularity in recent years. We report the results(More)
All of the current modalities have a place in the treatment of diaphyseal humeral fractures. Functional bracing renders a high rate of union and seems to be a safe method of treatment for most closed fractures. Type II and III open fractures seem to respond best to plate fixation or external fixation, particularly when there are associated neural or(More)
Functional bracing is an effective therapeutic modality in the management of selected fractures of the tibia, humerus, and ulna, particularly low-energy injuries. In the case of tibial fractures, it is applicable only to reduced transverse fractures and to axially unstable fractures with an acceptable degree of shortening. The rate of union of tibial(More)
Six cadaveric legs were stripped of all soft tissue excluding the interosseous membrane and the tissues about the ankle joint and foot. Angular deformities were simulated in all planes to a maximum of 15 degrees for proximal, middle, and distal third levels following tibial resection and same-level fibular osteotomy. Anterior ankle arthrotomies allowed(More)
Two major design parameters to total hip arthroplasty which can be selected to optimize for anatomical variation are head diameter and neck length. By using a cadaveric pelvis mounted in a three-dimensional protractor, it was shown that increased head-neck diameter ratio results in increased range of motion, with decreased prosthetic impingement, and that(More)
The classic position of immobilization of Colles' fractures with the elbow in flexion, the forearm in pronation, and the wrist in volar flexion and ulnar deviation is probably the main reason for the common and rapid recurrence of the original deformity. Such a position places the brachioradialis muscle, a strong flexor of the elbow and the only muscle(More)
UNLABELLED In intact fresh cadaver specimens, we experimentally studied angular and rotatory deformities at the distal and middle levels of the forearm. The remaining pronation and supination motions were measured. When both bones of the forearm were angulated with a combined deformity (radio-ulnar or dorsovolar, or both) of 10 degrees, a loss of(More)
In a prospective study, 156 Colles' fractures were treated with a functional Orthoplast brace. Approximately one-half were braced in pronation and one-half in supination. One hundred and four were available for follow-up. Results were analyzed by type of fracture and position of immobilization (pronation versus supination). In evaluating the results, we(More)
