Résumé :

Distal radio-ulnar joint (DRUJ) injuries are under-reported in the paediatric population. No single study has discussed methods of DRUJ reconstruction in immature patients with chronic instability. We present a physeal sparing ligamentoplasty for chronic DRUJ instability and describe the outcomes in two patients. Two consecutive children with chronic DRUJ instability were treated using physeal sparing ligamentoplasy. After the failure of triangular fibrocartilage complex repair, reconstruction was done using palmaris longus tendon graft that was tunnelled through the distal radius epiphysis and wrapped subperiosteally around the ulnar neck. Graft was tied in a neutral forearm position. DRUJ stability was achieved in both patients. Grip strength averaged 90% of the healthy side. Prono-supination range of motion (ROM) averaged 88 and 86%, respectively, of the healthy side, without intraoperative nor postoperative complications. Our novel technique was effective in the regain of DRUJ stability with minor effect on the prono-supination ROM. Further studies are planned to experiment the biomechanical effectiveness of our technique.
