Upper Limb after Forearm Lengthening in Patients' and Physicians' Perspective.

BACKGROUND

The goal of this study was to perform a functional (subjective) and radiological evaluation of patients who had undergone forearm lengthening by distraction osteogenesis years before.

MATERIAL AND METHODS

Eleven patients with forearm shortening of various etiology were enrolled. They had undergone a total of 21 lengthening procedures. A retrospective analysis of radiological data was conducted and a subjective evaluation was accomplished by using a modified QuickDASH-9 questionnaire.

RESULTS

Average bone lengthening was 3.54cm, and mean lengthening index was 40.53day/cm. Eight pa-tients answered the questionnaire at a mean of 7.8yrs after the treatment. The mean questionnaire score was 9.75pts (of 36). Four patients rated the overall function of the affected limb as improved following distraction, while 3 patients were not able to see any improvement. One patient reported that the lengthening had impaired limb function. With regard to cosmetic aspects, 4 patients reported a worsening after the lengthening procedure while 3 patients reported improvement and 1 patient did not note any changes.

CONCLUSIONS

1. Despite deformities and functional limitations, patients after forearm lengthening only occasionally suffered from moderate intensity pain. 2. The radiological outcomes were positive and the rate of complications was low. 3. The radiological outcomes did not match patient-declared functional and cosmetic results.
