초록

Purpose: The authors evaluated the differences between K-wires and Bold screw for fixing the proximal metatarsal
chevron osteotomy of moderate and severe hallux valgus.
Materials and Methods: There were 59 patients (81 feet) who were moderate and severe degree hallux valgus
according to the classification of Mann. They all got the proximal chevron osteotomy when correcting the deformity.
All patients were followed up at least 6 months. We divided the patients into 2 groups, K-wires fixed group as A,
Bold screw fixed group as B. Group A were 42 patients (63 feet) and Group B were 18 patients (19 feet). Among the
Group B, 2 feet who were failed to fix the oetotomy site with Bold screw, were fixed with K-wires during operation.
We measured the AOFAS score preoperatively, postoperatively and at final follow-up, VAS score at 2 weeks after the
operation. Also preoperative, postoperative and follow-up hallux valgus angle (HVA) and intermetatarsal angle (IMA)
were measured for each patients.
Results: Mean follow up period was 1.34 year (range: 6 months-6.16 years). Mean VAS score of group A was 3.21±1.7
and group B 1.76±1.0. Preoperative mean AOFAS score of group A was 45.61±8.3, group B 44.41±8.9, the final mean
score of group A was 88.87±8.3 and group B 92.47±4.4. Preoperative mean HVA was 30.82±6.6 degrees in group
A and 32.88±14.5 degrees in group B, the final mean angle of group A was 14.89±8.3 degrees and group B
17±4.4 degrees. The preoperative mean IMA of group A was 13.69±3.6 degrees and group B 12.35±5.2, the final mean
angle of group A was 9.26±3.6 degrees and group B 12.35±5.8 degrees.
Conclusion: There were no statistical differences in radiologic and clinical results (p>0.05) but, group B exceeded
group A in VAS score (p=0.0007) and had no statistical significance in terms of reduction angle loss (p=0.06). Early
returning to normal life activity may be possible for patients using Bold screws.
