The use of suture anchors in akin osteotomy : a new surgical technique

Abstract

To perform an Akin osteotomy using suture anchors to achieve stability of the osteotomy line and avoid the need for a further operation to remove an implant. Akin osteotomy using suture anchors was performed on 35 feet of 30 patients (21 female, 9 male ; mean age 45 years, range 18-60 yrs) diagnosed with hallux valgus. In bilateral cases, surgery was firstly carried out on the foot in the more serious condition, followed by the second foot 2 months later. Preoperative and postoperative clinical evaluation of the patients was made using American Orthopaedic Foot and Ankle Society (AOFAS) scores. Preoperative AOFAS values for pain, function and alignment were measured. Pain values were 8 patients 20 points, 27 patients 0 points. Function values were, activity, 14 patients 4 points, 21 patients 0 points ; footwear requirements, 18 patients 5 points, 17 patients 0 points, MTP joint movement, 11 patients 5 points, 24 patients 0 points, Post-operative AOFAS values were measured and evaluated as follows. Pain values were 33 patients 40 points, 2 patients 30 points. Function values were, activity, 30 patients 10 points, 5 patients 7 points ; footwear requirements,32 patients 10 points, 13 patients 5 points. MTP joint movement, 22 patients 10 points, 13 patients 5 pointsThese results were found to be statisically highly significant (p<0.001). Rigid fixation was achieved with suture anchors and patients made an early return to normal activities. Postoperative shoes were used for early mobilisation.
