The Hip Society - 2001 Open Meeting (9635 words) |
 | Sixty-eight well-fixed cups with osteolysis in the pelvis and polyethylene wear were identified from a series of 124 consecutive re-operations for failed cementless sockets. |
| Radiographic measurements were fixation of the socket and stem; osteolysis of pelvis and femur; and penetration (creep) of the plastic liner in the metal shell. |
| There was no mechanical failure rate of fixation, no osteolysis, and less than 0.04 mm of creep of the polyethylene liner which means that the center of rotation of the femoral head remains in the center of the cup. |
| The Physician and Sportsmedicine: Osteolysis of the Distal Clavicle (1706 words) |
| In Brief: Osteolysis of the distal clavicle is a pathologic process involving resorption of the distal clavicle and is usually posttraumatic or caused by the repetitive microtrauma of weight lifting. |
| Osteolysis of the distal clavicle is typically associated with AC pain and, on radiographs, a loss of subchondral bone detail, AC separation, and cystic changes (1). |
| The mechanical cause of atraumatic osteolysis appears to be repetitive microtrauma to the shoulder (eg, caused by weight-training exercises), whereas traumatic osteolysis is induced by a single blunt trauma to the shoulder. |
