As a result of the increasing number of weapons in this country, as many as 500,000 missile wounds occur annually, resulting in 50,000 deaths, significant morbidity, and striking socioeconomic costs. Wounds are generally classified as low-velocity (less than 2,000 ft/sec) or high-velocity (more than 2,000 ft/sec). However, these terms can be misleading;(More)
In vivo bone strain experiments were performed on the ulnae of three female rhesus macaques to test how the bone deforms during locomotion. The null hypothesis was that, in an animal moving its limbs predominantly in sagittal planes, the ulna experiences anteroposterior bending. Three rosette strain gauges were attached around the circumference of the bone(More)
The magnitude and clinical significance of Hepatitis C virus (HCV) infection in dialysis patients is controversial and underestimated. This study was conducted in order to evaluate the correlation between HCV replication and antibody response to HCV in dialysis patients. HCV infection in dialysis patients was evaluated over a period of 3 years and compared(More)
The reduction-association scapholunate (RASL) procedure for stabilization of the scapholunate joint is an alternative to soft-tissue procedures that do not maintain normal carpal alignment, despite reports of good symptomatic relief. The RASL procedure--indicated for patients with scapholunate instability or scapholunate dissociation without arthritis and,(More)
Certain massive defects of the rotator cuff tendinous insertion cannot be repaired primarily to the greater tuberosity. If restoration of strength is an important treatment goal to the patient, then a tendon transfer may be considered. Ten cadaver shoulders were dissected to define the anatomy of the latissimus dorsi tendon (LDT) and its distance(More)
Angiogenesis is considered essential to fracture healing, but its role in the healing process remains poorly understood. Angiogenesis inhibitors, which block new blood vessel formation by specifically targeting vascular cells, are currently under development for use in cancer chemotherapy, and are potentially powerful tools for defining the consequences of(More)
A phylogenic review shows the DRUJ to be a highly evolved and specialized structure. The diarthrodial joint, in combination with the TFCC, ligament complex, and oblique fibers of the distal interosseous membrane, permit rotation while preserving stability and transmitting the load borne by the radiocarpal joint to both bones of the forearm. Our improved,(More)
Fracture nonunion, delayed union, and osteomyelitis remain serious problems with substantial morbidity and mortality rates. Healing promoters, including bone morphogenic proteins, fibroblast growth factors, and transforming growth factor-beta, regulate bone growth in experimental models, such as those employing a "critical gap" to establish nonunion, but(More)
UNLABELLED We investigated the feasibility of arthroscopically assisted reduction and fixation of small coronoid fractures and the anterior capsule for treatment of patients with Regan and Morrey Types I and II (O'Driscoll Types I and II) coronoid fractures with instability of the ulnohumeral joint. Four consecutive patients with this fracture type(More)
