The operative management of pelvic ring fractures and dislocations is difficult. Posterior pelvic ring disruptions are often associated with severe soft-tissue injuries and high infection rates. Percutaneous iliosacral screw fixation of the posterior pelvis has become popular with improved fluoroscopic imaging techniques. The percutaneous iliosacral screw(More)
The purpose of this study was to evaluate pubic ramus fracture fixation. This biomechanical evaluation compared standard plating techniques with retrograde medullary screw fixation of a superior pubic ramus fracture in a pelvic fracture model. Six fresh-frozen, cadaveric pelvic specimens with a mean age of 79 years were harvested. These specimens were(More)
Retrograde medullary screws were used in 26 patients with unstable pelvic ring injuries to stabilize the superior public ramus fractures. The posterior pelvic ring fractures and dislocations were fixed with iliosacral screws. The retrograde screws were inserted after closed manipulative reductions of the superior pubic ramus fractures in 15 patients and(More)
OBJECTIVE To report on the early complications related to the percutaneous placement of iliosacral screws for the operative treatment of displaced posterior pelvic ring disruptions. STUDY DESIGN Prospective, consecutive. SETTING Level-one trauma center. PATIENTS One hundred seventy-seven consecutive patients with unstable pelvic ring fractures. One(More)
This study evaluates the morbidity of harvest of both the semitendinosus and gracilis tendons for anterior cruciate ligament reconstruction on nine patients at a minimum of 3 year follow-up. Specifically, the effect on knee function, knee extension and flexion strength, the size of the individual posterior thigh muscles, and the extent of retraction of the(More)
We treated 17 knees in 15 patients with severe ligament derangement and dislocation by open repair and reconstruction. We assessed the competence of all structures thought to be important for stability by clinical examination, MRI interpretation, and surgery. Our findings showed that in these polytrauma patients clinical examination was not an accurate(More)
A rare case of Candida infection after revision total knee arthroplasty that was treated medically, without amphotericin B or resection arthroplasty, is reported. This case occurred in an elderly patient without predisposing medical problems. The patient was treated with only a suppressive dose of ketoconazole. The patient was last evaluated 6 years after(More)
BACKGROUND Exact reconstruction of an osteochondral defect by autogenous transplantation (mosaicplasty) is difficult given the variation in joint surface contour. Clinical and experimental studies do not show the extent to which incongruity can be tolerated in autografting. HYPOTHESIS Grafted articular cartilage will hypertrophy to correct the incongruity(More)
The purpose of this study was to document the effect of muscle fatigue on glenohumeral kinematics. Twelve male volunteers without shoulder disease and with an average age of 27 years were studied. Glenohumeral anteroposterior radiographs were taken at 45 degrees intervals as the arm was abducted in the plane of the scapula from 0 degree to 135 degrees. This(More)
Many conflicting studies have been performed evaluating the effects of sterilization and storage treatments on the mechanical properties of allograft bone. In the current study, four right and left matched, sterile, deep-frozen, tibial pairs from human donors with an average age of 32 years were tested. One tibia from each pair served as a matched control(More)
