The modified Bosworth technique for the treatment of acute traumatic Achilles tendon rupture.

Between 1983 and 1994, 15 patients (range 18 to 62 years) with acute traumatic Achilles tendon rupture, were treated surgically in our Department. We employed a modified Bosworth technique. The modifications were the use of a shorter strip of tendon and more secure fixation of the proximal and distal stump, than the original Bosworth technique. Postoperatively an above - knee plaster cast was applied with the knee flexed 30°-40° and the foot in a relaxed equinus position. The plaster cast was changed to a below - knee after 4 weeks and the foot gradually dorsiflexed to a neutral position until the 8th week, and then the plaster cast was removed. No patient had wound separation, infection or skin sloughs. After an average follow-up of 9 years, no rerupture has been reported and all the patients have returned to their pre injury activities.
