Randomiseret sammenligning af genanvendelig stövle og letvaegtsgips til behandling af
förstegangs akillesseneruptur
Sammanfattning
Introduction: The aim of this study was to compare a CAM walker to a traditional cast. We expected the CAM walker to be comparable. Material and methods: Fifty patients with a first time rupture of the Achilles tendon were randomised to either a cast or a CAM walker. Both groups were immobilised for eight weeks. All patients were examined four and 12 months after the injury. Results: We found five reruptures in 29 patients treated with a cast (17%). No reruptures occurred in 21 patients treated with a CAM walker. The difference was not statistically significant (p=0.066). There was no difference in age, sex, patient satisfaction, dominant/non dominant leg, muscle strength, or range of motion. Discussion: The CAM walker is a useful alternative to a cast, with few complications and lower costs. Owing to the risk of type two error (44%), it is possible that we could have found a significant difference in the number of reruptures if the number of patients had been larger.
