More evidence of educational inadequacies in musculoskeletal medicine

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 musculoskeletal education? Does additional clinical experience in musculoskeletal medicine improve understanding of the basic facts and concepts introduced in a second-year course? A modified version of an exam used to assess the competency of incoming interns at the University of Pennsylvania was used to assess the competency of medical students during various stages of their training at the University of Washington. Despite generally improved levels of competency with each year at medical school, less than 50% of fourth-year students showed competency. Students who completed a musculoskeletal clinical elective scored higher and were more competent (78%) than students who did not take an elective. These results suggested that the curricular approach toward teaching musculoskeletal medicine at this medical school was insufficient and that competency increased when learning was reinforced during the clinical years.

High reoperation rates after early treatment of the subluxating hip in children with spastic cerebral palsy.

Abstract: 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 reduced hips in severely involved children. A series of 60 patients with spastic cerebral palsy and hip subluxation younger than 6 years who underwent primary bilateral hip surgery at one hospital between 1980 and 1996, with a minimum of 4 years of follow-up, were retrospectively reviewed. Fifty-two patients had spastic tetraplegia and 47 were nonambulators. Measures of proximal femoral and acetabular development were made via radiographic analysis. Twenty-two patients underwent primary bilateral soft tissue procedures. At a mean 6-year follow-up, there was modest improvement seen in mean femoral head coverage and little improvement seen in mean indices of acetabular development. Seventeen of these 22 patients (77%) underwent reoperation. Thirty-eight patients underwent primary bilateral varus derotational osteotomies. At a mean follow-up of 5 years, there was also modest improvement noted in mean femoral head coverage with little change in the mean indices of acetabular development. Twenty-eight of these 38 patients (74%) underwent reoperation. In this population of severely involved patients with spastic cerebral palsy, the reoperation rate was high. Acetabular remodeling did not reliably occur as a result of either early soft tissue or proximal femoral procedures when performed at an average age of 4 years.

Malignant progression in two children with multiple osteochondromas.

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 two cases of skeletally immature patients with MO who presented with rapidly enlarging and radiographically aggressive lesions consistent with malignant transformation. Both underwent allograft reconstruction of the involved site with no signs of recurrence or metastatic disease at a minimum of four-year follow-up.
