Description
Summary:Forearm deformities are often observed in patients with hereditary multiple osteochondroma, resulting in functional disability and cosmetic impairment. The aim of this study was to assess clinical and radiological outcomes after corrective osteotomy of the radius (COR). We performed a retrospective analysis of clinical and radiologic data from patients with forearm deformities who underwent COR combined with osteochondroma resection between 1978 and 2015. Seventeen patients (17 forearms) were included. The mean (range) age at surgery was 11.8 years (3.2–14.4), and the mean interval between surgery and last follow-up was 8.2 years (2–34.2). Range of motion was moderately increased and postoperative radiological assessments found significant improvements in ulnar variance, radial articular angle, bowing of the radius, and carpal slip. At last follow-up, a loss of ulnar variance correction was noted in 11 cases (mean loss: 4mm). The mean score on the Quick Disabilities of the Arm, Shoulder and Hand self-administered questionnaire was 13.9. Our results show that a forearm deformity in a patient with hereditary multiple osteochondroma is an appropriate indication for COR combined with osteochondroma resection and should be performed at the end of growth. This simple, safe technique corrects bowing of the radius and radius-ulna length discrepancy and could limit the risk of radial head dislocation. IV. Les déformations de l’avant-bras sont fréquemment observées chez les patients atteints de maladie des exostoses multiples, entraînant une limitation des amplitudes articulaires et parfois une gêne esthétique. L’objectif de notre étude était d’évaluer les résultats cliniques et radiologiques après une ostéotomie de correction du radius (OCR). Nous avons réalisé une analyse rétrospective des données cliniques et radiologiques de patients atteints de déformations de l’avant-bras ayant été opérés d’une OCR associée à une résection d’exostoses entre 1978 et 2015. Dix-sept patients (17 avant-bras) ont été inclus. L’âge moyen au moment de la chirurgie était de 11,8 ans (3,2–14,4 ans) et l’intervalle moyen entre la chirurgie et le dernier suivi était de 8,2 ans (2–34,2 ans). Les amplitudes articulaires étaient modérément augmentées, et les évaluations radiologiques postopératoires ont montré des améliorations significatives de la variance ulnaire, de l’angle articulaire radial, de la courbure du radius et du glissement du carpe. Lors du dernier suivi, une perte de correct
