Early Functional Outcomes and Complications of Tibial and/or Peroneal Sesamoidectomy Utilizing a Burr Through a Medial Approach

Background: Sesamoid pathology can lead to significant pain and disability both with activities of daily living and high-impact athletic movements. Sesamoidectomy is a widely used procedure for patients who fail conservative treatment measures. Traditional dorsal or plantar approaches for sesamoidectomy have shown to successfully alleviate pain, but complications were reported. A proposed alternative medial approach using a burr may provide many advantages compared with traditional approaches. This study presents patient outcomes and complications for this technique.

Methods: This was a retrospective chart review of patients undergoing sesamoidectomy (tibial, peroneal, or both) using a burr through a medial approach to the sesamoid metatarsal articulation. Data collected included patient demographics, radiographic analysis, and outcomes: Veterans Rand 12 Item Health Survey (VR-12), Foot and Ankle Ability Measure (FAAM), visual analog scale (VAS), patient satisfaction, and complications.

Results: Twenty-seven patients (29 feet) were included. The mean age was 38.4 years followed up for a mean of 30.9 months. VR-12 physical component improved from 35.98 ± 7.86 to 51.34 ± 8.01 (P < .001), FAAM ADL and sport improved from 58.33 ± 16.61 to 83.27 ± 18.28 (P < .001) and 26.37 ± 20.31 to 63.75 ± 29.74 (P < .001), respectively. Patient satisfaction with the treatment was 80.59% ± 27.06%. The overall complication rate was 11 (37.9%) whereas the overall reoperation rate was 4 (13.7%) of 29 feet. Complications included 1 arthrofibrosis, 1 flexor hallucis longus subacute rupture, and 1 asymptomatic hallux valgus. There were no sesamoid excision revisions.

Conclusion: Sesamoidectomy using a medial approach with a burr provided significantly improved short-term functional outcomes, 80% patient satisfaction rate, with a relatively acceptable complications rate including 20% persistent pain. The medial approach is familiar to orthopaedic foot and ankle surgeons, provides adequate exposure, and eliminates the possibility of a painful plantar scar while avoiding disruption of the plantar plate, flexor hallucis brevis tendon, and ligamentous structures attached to the sesamoids. Larger studies with long-term follow-up from other centers are needed.
