Purpose: A retrospective review of the radiographs of the proximal metatarsal osteotomy and distal soft tissue procedure for hallux valgus, evaluating the correction of the tibial sesamoid, was undertaken. We evaluated the correlation between the reduction of the tibial sesamoid and the clinical outcomes.
Materials and Methods: 17 patients (23 cases) with moderate to severe hallux valgus deformity underwent the proximal metatarsal osteotomy and distal soft tissue procedure. The preoperative and last follow-up radiographs were reviewed according to the tibial sesamoid grade classification recommended by the Research Committee of the American Orthopedic Foot and Ankle Society (AOFAS). We divided them into two groups according to the reduction of the tibial sesamoid. We anaylyzed the clinical outcomes in each group according to Mayo Clinic Forefoot Scoring System (FFSS).
Results: In all of the patients, the preoperative tibial sesamoid position were grade 2 or greater. At the last follow-up, 52% (n=12) were grade 1 or less (Group I) and 48% (n=11) were grade 2 or greater (Group II). In group I, the forefoot score was improved from preoperative mean value of 32.0 points to final follow-up value of 66.3 points. In group II, the forefoot score was improved from preoperative mean value of 31.7 points to final follow-up value of 65.9 points. There was no statistical significance between postoperative, average scores in group I and II (p>0.05).
Conclusion: The position of the tibial sesamoid was corrected insufficiently in almost half of all cases. In view of clinical outcomes, there was no significant difference between the corrected group and the other group.
