Treatment of humeral shaft fractures with antegrade intramedullary locking nail.

Antegrade interlocked humeral nailing for stabilization of humeral fractures was introduced many years ago, and studies on this method in the orthopedic literature have shown mixed results. The purpose of this investigation was to document the clinical outcome and complications associated with the use of an antegrade intramedullary nail (T2, Stryker) for the humeral fractures. Between 2005 and 2008, 52 fractures of the humeral shaft were treated operatively with this intramedullary nail in our department. Eight patients were polytraumatized, and four patients had an open fracture. The mean age of patients was 51.7 years. Forty-eight patients had an adequate duration of clinical follow-up (a mean of 18 months) for analysis. Complications were recorded, and the time to union was measured. Shoulder and elbow functions were assessed using the Constant Score and the Morrey Score, respectively. Forty-six fractures healed, with a mean time to clinical union of 10.3 weeks. Two patients developed pseudarthroses. There were four adverse events: two proximal screws backed out, one superficial infection at the insertion point, and one fracture at the distal end of the nail. Ninety-one percentage of patients had an excellent or good shoulder function. Five further operations were necessary: two for treatment of pseudarthroses, two for removal the backed out proximal screws, and one wound debridement for superficial infection. Antegrade humeral nailing is a valid therapeutic option for stabilization of humeral shaft fractures. By strictly adhering to the operation technique, the number and the severity of complications can be reduced. When good fracture alignment and stability are obtained, uneventful bone healing with good functional results is the rule.

Bilateral and simultaneous rupture of the triceps tendons in chronic renal failure and secondary hyperparathyroidism.

BACKGROUND: We report a case of a 27-year-old (male) patient with bilateral and simultaneous rupture of the triceps tendons. He was suffering from chronic renal failure secondary to acute glomerulonephritis and for 4 years he underwent maintenance hemodialysis three times a week. This injury is extremely rare, and only one case has been reported in the international literature. Based on previous cases of tendon ruptures in patients with chronic renal failure, we believe that secondary hyperparathyroidism is the primary causative factor in his case. CASE REPORT: A primary repair was performed using heavy, nonabsorbable sutures passed through holes drilled in the olecranon with the technique described by Levy. The suture line was then protected with a figure-of-eight tension band wire. Our patient obtained full range of motion bilaterally within 3 months.
