| Popis: | Introduction Akin osteotomies are commonly fixed with a screw or staple. Hardware-related symptoms are not uncommon. We compared the outcomes and costs of the two implants. Methods We evaluated 74 Akin osteotomies performed in conjunction with first metatarsal osteotomy for hallux valgus. The osteotomy was fixed with a headless compression screw in 39 cases and a staple in 35 cases. We looked at the implant-related complications, removal of metalwork, revision, non-union and cost. Pre- and postoperative hallux valgus interphalangeal (HI) angles and length of the proximal phalanx were measured. Results There was 100% union, no failure of fixation, no revision surgery and no delayed union in either group. The radiological prominence of screws was significant (p=0.02), but there was no significant difference in soft-tissue irritation (p=0.36) or removal of implants (p=0.49). Two cortical breaches (5.8%) occurred in staple fixation and 4 (10.2%) in screw fixation (not statistically significant (NS), p=0.50). The mean improvement in HI angle was 4.3° with screw fixation and 4.1° with staple fixation (NS, p=0.69). The mean shortening of the proximal phalanx was 2.5mm with screw fixation and 2.3mm with staple fixation (NS, p=0.64). The total cost was £1,925 for staple fixation and £4,290 for screw fixation. Conclusions Staple and screw fixation are reproducible modalities with satisfactory outcomes, but screw fixation is expensive. We conclude staple fixation is a cost-effective alternative. |
