Background: Different regimens of early motion of the ankle after operative treatment of a ruptured Achilles tendon have been suggested since the late 1980s. However, as far as we know, no controlled studies comparing these regimens with conventional immobilization in a cast have been reported. Methods: In a prospective study, seventy-one patients who had an acute rupture of the Achilles tendon were randomized to either conventional postoperative management with a cast for eight weeks or early restricted motion of the ankle in a below-the-knee brace for six weeks. The brace was modified with an elastic band on the posterior surface, in a manner similar to the principle of Kleinert traction. Metal markers were placed in the tendon, and the separation between them was measured on serial radiographs during the first twelve weeks postoperatively. The patients were assessed clinically when the cast or brace was removed, at twelve weeks postoperatively, and at a median of sixteen months postoperatively. Results: The separation between the markers at twelve weeks postoperatively was nearly identical in the two groups, with a median separation of 11.5 millimeters (range, zero to thirty-three millimeters) in the patients managed with early motion of the ankle and nine millimeters (range, one to forty-one millimeters) in the patients managed with a cast. The separation was primarily correlated with the initial tautness of the repair (r[S] = 0.45). No patient had excessive lengthening of the tendon. The patients managed with early motion had a smaller initial loss in the range of motion, and they returned to work and sports activities sooner than those managed with a cast. Furthermore, there were fewer visible adhesions between the repaired tendon and the skin in the patients managed with early motion, and these patients were subjectively more satisfied with the overall result. The patients in both groups recovered a median of 89 percent of strength of plantar flexion compared with that of the noninjured limb, as measured with an isometric strain-gauge at 15 degrees of dorsiflexion. The heel-rise index was similar for both groups: 0.88 for the patients managed with early motion and 0.89 for those managed with a cast. Conclusions: Early restricted motion appears to shorten the time needed for rehabilitation. There were no complications related to early motion in these patients. However, early unloaded exercises did not prevent muscle atrophy. *No benefits in any form have been received or will be received from a commercial party related directly or indirectly to the subject of this article.

The aim of the present study was to evaluate the value of local anaesthesia versus the commonly used intravenous pethidine/diazepam in the reduction of acute secondary shoulder dislocations. Patients with a traumatic secondary dislocation of the shoulder were randomized to either locally injected lidocaine or intravenously injected pethidine/diazepam. The local method was performed with 20 ml of 1% lidocaine. The patients were observed for any complication during and after the procedure, and the methods used were evaluated with a visual analogue scale (VAS). From November 1991 to September 1993, 62 patients were admitted to our departments of whom 52 were included in the study. Average age was 47 years (range 18-89 years) with 24 men and 28 women. Twenty-six patients were randomized to pethidine/diazepam; 22 had a successful reduction, and 4 were failures. Twenty-six patients received lidocaine, of whom 18 were successful and 8 not. Three patients treated with the intravenous method suffered respiratory depression, and one required an antidote. No systemic or local side-effects, no neurovascular damage and no early or late superficial or deep infection were recorded in the lidocaine group. There was no statistical difference between the average VAS value in the two groups. Lidocaine used to reduce acute secondary dislocations of the shoulder is a simple and safe method. It is as effective as the standard intravenous method and is well accepted by patients.
In 18 patients scheduled for lower intraabdominal surgery (hysterectomy), changes in thyreotropin (TSH) thyroxine (T4), triiodothyronine (T3) binding of thyroid hormones to plasma proteins (T3-uptake) and glucose in serum were evaluated. In eight patients afferent neurogenic impulses from the surgical area were blocked (Th4-S5) with bupivacaine 0.5% infused continuously into the epidural space from the start of the operation until 6 h postoperatively. All patients received general anaesthesia with thiopentone, pethidine, pancuronium and nitrous-oxide plus oxygen. The patients receiving epidural analgesia had no increase in plasma-TSH, compared to the other group, which had a significant (P less than 0.05) increase peroperatively. The patients receiving epidural analgesia were pain-free and the normal stress-induced increase in plasma-glucose was abolished. Concerning T3 we found a significant decrease in both groups and a steady level of T4- and T3-uptake without significant fluctuations. Thus it can be concluded that the effects of surgical trauma on plasma-TSH concentration are markedly similar to the effects of other anterior pituitary hormones, i.e. HGH, prolactin and ACTH.
