Slipped capital femoral epiphysis: long-term results of an abandoned technique.

Abstract

Sixty-two (11 women and 51 men) of 76 consecutive patients treated between January 1960 and December 1979 with percutaneous pinning, traction, and ambulation in Thomas splints for slipped capital femoral epiphyses (physiolysis colli femoris; PCF) were re-examined radiologically and clinically to evaluate long-term results of an abandoned technique. Median follow-up time was 21 years (range: 8 to 28). The average age at symptom start was 14 years (range: 9 to 17). Fourteen patients were operated bilaterally, while 15 were operated on the right side only and 33 on the left side only. No additional hip surgery for coxarthrosis as adults had been performed. At the clinical examination the mean hip-movement-sum was 220 degrees (range: 30 degrees to 300 degrees). Pain occurred in 31 hips. A limp was found in 23 patients, and 56 had no impairment of working ability. At radiologic examination, 30 patients showed sequelae of PCF, and 30 (48%) had bilateral signs of PCF at follow up.
