[Severe and complex traumatic hand]. / Main traumatique grave et complexe.

SEVERE AND COMPLEX TRAUMATIC HAND . Serious and complex traumatic injuries of the hand are multiple tissue injuries (skin, vascular, bone and nerves), requiring urgent surgical management. They are responsible for significant functional and aesthetic sequelae. Their incidence is clearly decreasing thanks to information, prevention and security measures. The absolute emergencies are injections under pressure, amputations-devascularizations, and serious mutilations. The objective of the management is to make a functional and aesthetic hand: restoration of the opposition of the thumb with a key-pinch, a sufficient length thumb, and restoration of the sensitivity of the reconstructed hand. This calls for numerous surgical and microsurgical techniques and must be undertaken by trained teams in specialized centers.

MAIN TRAUMATIQUE GRAVE ET COMPLEXE. Les lésions traumatiques graves et complexes de la main sont des lésions tissulaires multiples (cutanées, vasculaires, osseuses et nerveuses), nécessitant une prise en charge chirurgicale urgente. Elles sont responsables de séquelles fonctionnelles et esthétiques importantes. Leur incidence est en nette diminution grâce aux mesures d'information, de prévention et de sécurité. Les principales urgences absolues sont les injections sous pression, les amputations-dévascularisations et les mutilations graves. L'objectif de la prise en charge de ces traumatismes est de rendre une main fonctionnelle et esthétique : restauration d'opposition du pouce, d'un pouce de longueur suffisante, d'une pince pollici-digitale termino-latérale, rétablissement de la sensibilité de la main reconstruite. Ceci fait appel à de nombreuses techniques chirurgicales et microchirurgicales et doit être entrepris par des équipes entraînées en centres spécialisés.

Upper limb congenital muscular hypertrophy and aberrant muscle syndrome in children.

Congenital muscle hypertrophy of the upper limb is a very rare condition with unknown aetiology. This descriptive observational and retrospective series included eight children followed by a multidisciplinary team from 2005 to 2017. The diagnosis was based on a cluster of clinical and radiological characteristics after elimination of differential diagnoses. Patients were categorized according to: anomalies of the wrist, anomalies of long fingers of intrinsic or extrinsic origin; and anomalies of the thumb with or without first web space contracture. Treatment begins in young children with hand orthoses to limit muscle contraction and joint malposition. The purpose of surgical treatment was to release contractures and to restore muscle balance through, in the main, finger intrinsic releases and first web releases. At the 2-year follow-up, we found that limited surgical procedures improved finger, thumb and wrist positions. We conclude that muscle hypertrophy is the main cause of deformity and that selective releases of contracted musculo-tendinous units and skin lengthening are effective. LEVEL OF EVIDENCE: IV.
