title: Injection-induced contractures of the quadriceps in childhood. A comparison of proximal release and distal quadricepsplasty.
abstract: Thirty-two contractures of the quadriceps induced by injection in 17 children have been reviewed. The average age at presentation was 3 years 4 months. All the children had suffered a severe illness within the first few weeks of life and all had received intramuscular injections into the thigh. Three methods of treatment were used: conservative, distal quadricepsplasty, and proximal release. At follow-up none of the patients treated by proximal release had an extension lag, which was present in 70% of those treated by distal quadricepsplasty. Apart from one case with slight improvement in the range of knee flexion, conservative treatment, at best, could only prevent further loss. The clinical presentation and management is described, and the advantages of proximal release are discussed.
