BACKGROUND The amount of correction obtained with tibial and/or femoral hemiepiphyseodesis in late-onset tibia vara is quite variable. The purpose of this study is to identify preoperative factors which might help to predict the amount of correction that is obtainable. METHODS Fifty-three patients (67 knees) have been treated with hemiepiphyseodesis and(More)
We have carried out a linkage analysis on 11 families segregating gene(s) for hereditary multiple exostoses (EXT). Four highly informative, short tandem-repeat (STR) markers that have been physically mapped to an interval surrounding the Langer-Giedion chromosomal region (8q24.11-q24.13) were used in a multipoint linkage analysis. Significant evidence for(More)
We established a database of hereditary multiple exostoses for the state of Washington, on the basis of a retrospective review of the medical records and a clinical evaluation of family members, to determine the prevalence, clinical range of expression, and rate of malignant degeneration. The database comprised forty-six kindreds with 113 affected members;(More)
Multiple Osteochondromas (MO) is a disease of benign bony growths with a low incidence of malignant transformation. Secondary chondrosarcoma in children is rare even in children with MO. Making a diagnosis of malignancy in low-grade cartilage tumors is challenging and requires consideration of clinical, radiographic, and histopathological factors. We report(More)
BACKGROUND Although most musculoskeletal illness is managed by primary care providers, and not by surgeons, evidence suggests that primary care physicians may receive inadequate training in musculoskeletal medicine. We evaluated the musculoskeletal knowledge and self-perceived confidence of fully trained, practicing academic primary care physicians and(More)
In their study, Freedman and Bernstein suggested that 80% of a group of graduates from many of the best medical schools in the United States were deficient in their knowledge of basic facts and concepts in musculoskeletal medicine. How do these results compare with results from students attending a medical school with a long-standing dedicated program to(More)
The material properties of the anterior cruciate ligament (ACL) in female rats with normal estrous cycles were compared to those regulated by oral contraceptive steroids. Forty female Sprague-Dawley rats were divided into two groups: an experimental group received daily ethinylestradiol and levonorgestrel in a dosing model designed to simulate a typical(More)
Dynamic ankle-foot orthoses (DAFOs), with free plantarflexion, are frequently prescribed to facilitate the gross motor skills of children with cerebral palsy. Employing a randomized crossover design, this project documents the short-term effect of DAFOs in 23 ambulatory children with cerebral palsy aged 1.9 to 7.3 years. Significant improvements in(More)
This is a retrospective analysis of 2 methods of fixation of the femoral component in 86 consecutive revision arthroplasties, for which all clinical and radiographic data were recorded prospectively. There were 56 cemented revisions using precoated femoral components followed for 2 to 8 years (mean, 4 years) and 30 uncemented, proximally porous-coated(More)
Hip subluxation and dislocation are well-recognized complications of spastic cerebral palsy. Alternatives for treatment include observation, bracing, or surgery. The purpose of this study is to compare the rates of reoperation and acetabular development after early soft tissue procedures with those of varus derotational osteotomies performed to maintain(More)
