Abstract
Purpose: A retrospective study was performed in order to evaluate the results of fixation of displaced unstable fractures of both bones of the forearm in children by intramedullary pins.
Materials and methods: During the last fifteen years 121 children with displaced midshaft fractures of the forearm were treated by open or closed reduction and smooth intramedullary pin fixation. The age range was 5–16 years, the mean 11 years. Seventy five children (62%) were operated upon primarily because of an irreducible fracture, and the remaining 46 (38%) were operated upon within two weeks after failed closed reduction. The arm was then immobilized in a plaster cast extending above the elbow. The average time for fracture healing and cast removal was 8 weeks. Afterwards the children were encouraged to move the elbow and wrist joints. The hardware was removed following a period of between 6 weeks to 5 years (average 5.5 months), under sedation or general anesthesia.
Results: Follow up was available in 91 of the 121 children for between 6 months to 15 years (mean 5.5 years). Using the grading scheme of Price, functional results at follow up were excellent in 79/91 patients (87%) and good in 12/91 children (13%). There were no fair or poor results. Of them, in 80 cases (88%), within one year from injury, a full range of movement was obtained in the elbow and wrist joints. 11 patients (12%) had an average loss of 10 degree of supination. In two cases there was a neuropraxia of interosseous nerves which disappeared spontaneously within 3 months. In one patient, a 16 year old boy, there was a delayed union of 6 months until solid healing. 4 patients had a mild degree of angulation of the distal third of the forearm. There were no incidences of deep infection, nonunion or damage to the epiphyseal plate.
Conclusion: In conclusion we found that smooth intra-medullary pinning for displaced midshaft fractures of the forearm in children is a good, simple and safe method.
