Open fractures of the forearm in children.

OBJECTIVE: To describe the epidemiology, early results of treatment, and complications associated with open fractures of the forearm in children. DESIGN: Retrospective review of patients treated according to protocol. SETTING: Level I trauma center. PATIENTS/PARTICIPANTS: All children with an open fracture of the forearm during a four-year period (n = 76). Fourteen patients were excluded because of inadequate follow-up or incomplete medical records. INTERVENTION: All fractures were treated with irrigation and debridement, and parenteral antibiotics. Twenty-five patients were managed with cast immobilization only, and the remaining thirty-seven, with internal fixation either with transcutaneous pins, intramedullary pins, or plates and screws, followed by immobilization in a cast. MAIN OUTCOME MEASUREMENTS: Time to union, angular alignment at union, and incidence of complications. RESULTS: The average time to union was 8.9 weeks (median, eight weeks; range, 6 to 17 weeks). There were no nonunions, but three of the sixty-two fractures had delayed union. Eight of the sixty-two fractures healed with an angular deformity of more than 10 degrees, and two developed infections, one deep and one superficial. There were three preoperative and four postoperative nerve palsies, which all resolved spontaneously. CONCLUSIONS: Open fractures of the forearm in children, treated with prompt administration of parenteral antibiotics followed by debridement, were associated with a fairly low incidence of complications. Although we found that the use of some form of internal fixation tended to reduce both the need to remanipulate these fractures (p = 0.08), and to minimize the incidence of angular deformity greater than 10 degrees (p = 0.16), these findings did not reach statistical significance.

Extensor carpi radialis brevis. An anatomical analysis of its origin.

We studied the origin of extensor carpi radialis brevis using 40 fresh frozen human cadaver specimens. Ten were stained with haematoxylin and eosin and trichrome which showed the collagenous structure of the extensor tendons at their origin. Gross anatomical observation showed that there was no definitive separation between brevis and communis at the osseotendinous junction. The histological findings confirmed the lack of separation between the two tendons. The extensor tendons were in close proximity to the joint capsule but trichrome staining showed no interdigitation of the tendon with the capsule. The validity of ascribing the pain of lateral epicondylitis to extensor carpi radialis brevis must be questioned. It appears to arise more from the 'common extensor' origin.

Adults with learning disabilities: occupational and social status after college.

Forty-nine adults with learning disabilities who had attended a large public university between 1980 and 1992 were interviewed about their current employment and social status. Most of the respondents had adjusted well to the demands and complexities of adulthood. More than 80% of the participants not still in college at the time of the interview were employed, mostly in white collar jobs. Although most of the participants indicated that their learning disabilities affected them at work or in other facets of their life, they typically did not disclose those disabilities when applying for jobs or once employed. The respondents were also socially active and happy with their social life. Keys and barriers to success are examined, and recommendations are made concerning the issue of discrimination in the workplace.

Comparison of the results of bacterial cultures from multiple sites in chronic osteomyelitis of long bones. A prospective study.

We evaluated the results of aerobic, anaerobic, and fungal cultures of specimens that had been obtained from multiple sites in thirty patients who had traumatic osteomyelitis with a sinus track. In each patient, we obtained specimens of material from the sinus track; specimens of purulent fluid, of soft tissue, and of bone obtained from curettage; and specimens from the bed of the involved bone. More than one organism grew on culture of the specimens from twenty-one of the patients; more than three organisms, from those of eleven patients; and ten organisms, from those of two patients. The same organisms grew on culture of the specimens from every site in only fourteen (47 per cent) of the thirty patients. We recommend that specimens of material from the sinus track; specimens of purulent material, of soft tissue, and of bone obtained from curettage; and specimens from the bed of the involved bone be obtained for culture before the treatment of chronic osteomyelitis with a draining sinus, so that as many of the infecting organisms as possible will be identified.
