Fixation of Akin osteotomy for hallux abductus with absorbable suture.

BACKGROUND

The Akin osteotomy is a widely used procedure where various fixation methods are available, predominantly with the use of metallic component (wire, screw, staple etc.). The aim of this study is to demonstrate the results of our modified Akin procedures, where the fixation of the phalangeal osteotomy is achieved by absorbable suture, without metallic component.

MATERIALS AND METHODS

Between July 2004 and October 2008, authors performed their first 22 consecutive Akin procedures with the above technique. Mean age of patients was 49 [standard deviation (SD) 17, range 19-69] years. Mean follow-up time was 26 (SD 13, range 8-57) months.

RESULTS

Mean correction of the distal articular set angle (DASA) was 9.4 (SD 7.1, range 5-28) degrees. Mean shortening of the proximal phalanx was 1.8 (SD 1.0, range 0.3-4.1) mm. Among the 22 osteotomies, there was no evidence of non-union, delayed union, excessive bone callus, or loss of correction. 100% of the patients would undergo the procedure again, 91% (20/22) were completely satisfied; and 9% (2/22) were satisfied, including the one complication case.

CONCLUSION

The method presented in this study for fixation of the akin osteotomy showed results identical to the ones using conventional (metal) fixation techniques concerning radiological (correction of DASA, shortening of the proximal phalanx), and clinical (complication rate, subjective satisfaction rate) findings, without the risk of complication due to hardware irritation.
