Repair of distal biceps tendon rupture using a suture anchor: description of a new endoscopic procedure.

BACKGROUND: Repair of a distal biceps tendon rupture is a challenging procedure and, to date, there is no consensus as to which technique should be used because of the specific complications reported for each. PURPOSE: A new endoscopic technique is described that uses a suture anchor to repair distal biceps tendon ruptures. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The results of a cohort of 23 patients (25 elbows) are reported with a median follow-up of 26 months. All patients were male and their median age was 44 years (range, 30-58). Ten of the patients (12 ruptures) were professional athletes or had a high level of physical activity. All repairs were performed via a 3-cm incision made in the "safe area" of the anterior crease of the forearm. The whole procedure was performed within the tendon sheath. The tendon was reinserted using a single anchor. RESULTS: Of the 23 patients, 22 were satisfied and 20 patients returned to their preinjury sports and jobs. There was a mean loss of 8.6 degrees of pronation and 5 degrees of supination. A single severe neurologic complication, which required a second surgical procedure, was reported. There were also 2 ectopic ossifications without clinical consequences and a transitory radial nerve paralysis. CONCLUSIONS: This study clearly demonstrated that endoscopic repair of the ruptured distal biceps tendon is safe, effective, and reproducible. It provides good functional outcome and early recovery with few complications. Postoperative median nerve palsy due to edema is a possible concern for patients involved in athletic activity and with a history of nerve entrapment; thus this technique should be used with caution in this group of patients.

Is the intersection syndrome is an occupational disease?

The intersection syndrome, described since the 19th century, is an uncommon disorder associated with the abductor pollicis longus and extensor pollicis brevis bellies (first dorsal compartment) rubbing against the extensor carpi radialis longus and brevis tendons (second dorsal compartment). Overuse occurred in occupational setting was barely described although it could lead to compensation by the French health insurance system. We reported a case of an intersection syndrome in a 58-year-old man who recently became a supermarket cashier. This job involved repeated extension and flexion of the wrist. The disorders arose after a minimal traumatism. Since it is recognized as an occupational disease, compensated ending of the activity causing the disorder could have been obtained.

A New Route to Thio- and Selenosulfonates from Disulfides and Diselenides. Application to the Synthesis of New Thio- and Selenoesters of Triflic Acid.

Alkyl and aryl trifluoromethanethiosulfonates(1) (or selenosulfonates) were prepared in one step either from alkyl and aryl sulfenyl (or selenenyl) chlorides and sodium trifluoromethanesulfinate (3) or, more generally, from disulfides (or diselenides), 3, and bromine. The second method involved trifluoromethanesulfonyl bromide as key intermediate. Benzenethiosulfonates were obtained in a similar way from disulfides, benzenesulfinate, and bromine but benzeneselenosulfonates could not be obtained by the same method from diselenides.
