Injuries to the hallucal sesamoid complex are uncommon, but they can cause significant pain. The medial sesamoid is the most common site of pain, but the fibular sesamoid can also become symptomatic. The most common clinical entities that lead to chronic fibular sesamoid pain are fracture nonunion and osteonecrosis. The purpose of this study was to describe the technique and determine the results of the dorsolateral approach for fibular sesamoid excision.
During an 11-year span, 8 patients underwent fibular sesamoidectomy using a dorsolateral approach after a minimum of 6 months of nonoperative treatment. The mean age was 33 years (range, 22 to 43 y). The average follow-up was 97 months (range, 24 to 167 mo). Patients were assessed using the AOFAS forefoot grading scale and a subjective rating for walking, pain, and overall satisfaction.
Fibular sesamoidectomy was performed for osteonecrosis in 3 patients and for nonunion in 5 patients. Four patients had work-related injuries. Two injuries were due to trauma and the rest were chronic, without a known cause. The average length of nonoperative care was 107 weeks and included rest, injections, physiotherapy, bracing, casting, NSAIDs, and orthotics. Overall, the patient subjective satisfaction was 5 excellent and 3 good. The mean AOFAS forefoot score was 91 and average time to return to activity was 15 weeks. The mean pain rating was 1.3/5, and the mean subjective walking score was 4.625/5.
Compared with previously published reports, our results for isolated fibular sesamoidectomy show similar satisfaction rates with equivalent time to return to activities and a low complication rate while avoiding a plantar incision.
