External Fixation for Pseudoarthrosis of Upper Extremity Long Bones.

Dynamic injury tolerances for long bones of the female upper extremity.

This paper presents the dynamic injury tolerances for the female humerus and forearm derived from dynamic 3-point bending tests using 22 female cadaver upper extremities. Twelve female humeri were tested at an average strain rate of 3.7+/-1.3%/s. The strain rates were chosen to be representative of those observed during upper extremity interaction with frontal and side airbags. The average mome...

External Power in Upper-Extremity Prosthetics and Orthotics

Coracoacromial pins to augment external fixation of the upper humerus.

present as soft-tissue masses; they may be painful and progressively enlarge. Radiography may show some calci fication, but bony erosion is rare (Sim et al 1977). The lesion can be clearly defined by CT. Extra-articular synovial chondromatosis has a benign clinical course (Dahlin and Salvador 1974), but in unusual locations it may be misdiagnosed as a soft-tissue chon drosarcoma. Factors which ...

Implant Removal Matrix for the Upper Extremity Orthopedic Surgeon

Orthopedic implant removal is a commonly performed procedure. While implant removal can be associated withimproved symptoms, risks of the surgery are notable. Stripped screws, broken and retained hardware, and morbidityassociated with soft tissue compromise during difficult removal are all common. Familiarity with the instruments iscritical to procedure success. The purpose of...
