Complications associated with hinged external fixation for chronic elbow dislocations.

PURPOSE: To evaluate the outcomes of patients who underwent application of hinged external fixators for chronic elbow fracture-dislocations. We hypothesized that patients treated for this injury pattern can achieve satisfactory outcomes but encounter many complications and require numerous additional procedures. METHODS: We performed a retrospective review of 7 patients who were surgically treated with application of a hinged external fixator for chronic ulnohumeral elbow fracture-dislocation. Patients were included only if they had complete ulnohumeral dislocation of greater than 1 month's duration. Demographics, injury pattern, and range of motion were documented. Preoperative and postoperative range of motion was recorded and any treatment complications or additional surgeries were noted. RESULTS: The interval between the initial injury and index procedure averaged 8 months. All patients underwent initial treatment with open reduction internal fixation. Average arc of ulnohumeral motion improved from 26° (range, 0° to 60°) to 120° (range, 100° to 145°). Overall, 4 of 7 patients developed at least one complication during treatment. Three patients required additional procedures aside from removal of the hinged external fixator. These 3 patients underwent a total of 13 additional procedures. CONCLUSIONS: Although patients can achieve good outcomes, realistic expectations should be set. Patients should be aware that surgery can be associated with a high risk of complications, potential treatment failure, and a need for additional surgical procedures. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Avulsion injuries of the nail bed do not need nail bed graft.

From 1985 to 1992, 12 cases of severe avulsion injuries of the nail bed were treated by allowing the nail bed to regenerate naturally, without a nail bed graft irrespective of the extent of nail bed loss. This involved simply covering the residual nail bed with the nail splint for a period of approximately 6 weeks or until the nail bed was observed to be fully regenerated. The patients were then followed up until full nail growth. It was observed that the nail bed regenerated spontaneously, followed by a normal nail growth identical to the contralateral uninjured nail.Proper coverage of the nail bed protected the culture milieu conducive to natural nail bed regeneration, and nail bed grafting was not necessary irrespective of the extent of tissue loss.
