Comminuted fracture-dislocations of the elbow treated with an AO wrist fusion plate.

Comminuted fracture-dislocations of the elbow are complex injuries that can result in significant postoperative loss of motion. Rigid anatomic fixation with early range of motion is the required treatment. Because of the local anatomy of the proximal ulna, it often is difficult to achieve a rigid fixation construct. A fixation technique of a dorsally applied AO limited contact-dynamic compression wrist fusion plate contoured to fit the anatomy of the proximal ulna is presented. Advantages of the AO wrist fusion plate in comminuted olecranon fractures include the ease of contouring, a low profile, and the use of variable screw hole sizing to achieve stable fixation. The hybrid design allows for rigid 3.5-mm plate fixation distally while providing low profile 2.7-mm plate fixation over the subcutaneous olecranon. The technical and biomechanical features of this plate make it an ideal alternative for fixation of these complex injuries.

Complications of thyroid surgery.

The current study reports complications from thyroidectomy in 253 consecutive patients from 1988 to 1992. There were 10 temporary cases of hypoparathyroidism. After total thyroidectomy, one of 34 patients (3.2%) developed permanent hypoparathyroidism. Complications of recurrent laryngeal nerve (RLN) injury or hypoparathyroidism were no more common following completion thyroidectomy than total thyroidectomy. Unplanned RLN injury was seen in 13 patients of which 7 were permanent (2.1% of 334 nerves at risk). All 13 patients with RLN injury experienced a reduction in speech "loudness", but only 3 reported "hoarseness". The RLN may be injured without serious vocal disability. Eleven of 171 right RLN's at risk were injured as compared to 2 of 163 left RLN's. The volume of thyroid tissue resected was positively associated with RLN injury (p < 0.05) and not hypoparathyroidism. These findings are discussed. Hypoparathyroidism, not "symptomatic" RLN injury, is the most problematic complication impacting on the decision whether or not to perform total or completion thyroidectomy.
