Randomized Controlled Trial Comparative Study[Postoperative analgesia following trapeziectomy with continuous intra-articular infusion of ropivacaïne versus continuous perineural infusion. A prospective randomised study].
A prospective randomised study on 46 patients was performed to evaluate postoperative analgesia after trapezectomy. We compare the efficacy of an in situ catheter 777 (ISC) positioned by the surgeon in the space of the trapezectomy (26 patients) with an axilliary perineural catheter (APC) positioned preoperatively by the anaesthetist (20 patients). The patients were followed-up postoperatively for 48 hours and assessed at 3, 7, 24 and 48 hours, recording pain (VAS), consumption of intravenous rescue analgesia and recovery of sensory and motor function. ⋯ The in situ catheter provided at least as good postoperative analgesia while requiring considerably less time and expertise to site. There was also more rapid recovery of motor and sensory function in patients treated with in situ catheters.

The vague term of capitellar fractures is still frequently used to designate articular coronal fractures of the distal humeral epiphysis. The use of eponyms for their descriptions may cause confusion. Recent publications describe a wide variety of fracture types and recommend new classifications based on the operative findings. We report our results of surgical treatment of 12 cases of these fractures in comparison to recent series of the literature. ⋯ Articular coronal fractures of the distal humerus are rare. The classification of Dubberley et al. (2006) [7] is comprehensive and allows inclusion of all varieties of these fractures. In addition, it is the only one that indicates the surgical approach according to the fracture type. However, to do so, a preoperative CT-scan is highly recommended. The more the fracture line extends medially to involve the trochlea (types 2 and 3), the less a lateral approach is sufficient and the more a combined lateral and medial or a posterior transolecranon approach is mandatory. An internal fixation using conventional small fragment screws inserted from posterior to anterior is feasible when the articular fragment has a sufficient subchondral bone thickness. A direct anteroposterior fixation is better achieved using headless screws buried beneath the cartilaginous surface; it is particularly helpful when the articular fragment has a thin sub-chondral cancellous bone component. Excision is reserved for comminuted fractures, those not amenable to fixation, very thin or osteoporotic fragments, and for the late diagnosed fracture.
