A versatile method for dorsal-approach plantar plate repair using standard operative instruments.

ABSTRACT:

Background

The plantar plate is an important static stabilizer of the lesser metatarsophalangeal joints, and disruptions of the plantar plate can lead to significant instability and lesser toe deformities. In recent years, direct plantar plate repair has been proposed. Although direct repair via a dorsal approach is attractive, a torn plantar plate is small and difficult to access using regular instruments in a restricted operative field.

Methods

In this report, a unique method for plantar plate repairs was used to repair various configurations of plantar plate tears with standard operative instruments that are available in most operating rooms.

Results

Using this method, 10 patients underwent plantar plate repairs, and the mean follow-up period was 24 (range, 14-38) months. The mean visual analog scale score for pain preoperatively was 4.1 (range, 0-6) and decreased to 0.6 (range, 0-3) at last follow-up. Postoperatively, the mean visual analog scale score for satisfaction was 9.6 (range, 8-10) and the mean American Orthopedic Foot and Ankle Society forefoot score was 88.8 (range, 75-100).

Conclusions

Our study proposes an inexpensive and versatile method for plantar plate repair via a dorsal approach that uses standard operative instruments.

Project description:BackgroundMetatarsalgia and plantar plate tears are characterized by forefoot pain and toe deformity in severe cases. Conservative management may slow progression of symptoms; however, definitive treatment often requires operative intervention. The purpose of this observational study was to evaluate the combination of plantar condylectomy and surgical imbrication of the plantar plate to the metatarsal neck to repair grade 0 plantar plate injuries.MethodsWe retrospectively identified 22 patients with metatarsalgia and low-grade plantar plate lesions (grade 0), operated between 2018 and 2021, who underwent operative repair involving plantar metatarsal condylectomy and proximal surgical imbrication of the plantar plate to the metatarsal neck. Fourteen patients underwent concomitant hallux valgus correction. Data collection was performed preoperatively and postoperatively and included Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) and pain interference (PI) scores. Paired Wilcoxon signed-rank tests compared PROMIS PF and PI scores at patients' preoperative, 6-9-week, 3-4-month, 5-6-month, and ≥9-month follow-up evaluations (P < .05).ResultsCompared to their preoperative visit, patients demonstrated modest improvement in their PROMIS (pain and physical function) scores over the first ≥9 months postoperatively (median 13.0 months). Median preoperative and most recent PROMIS physical function scores were 40.5 (95% CI: 36-49) and 44.5 (95% CI: 40-52), respectively. Median PROMIS pain interference scores changed from 62.5 (95% CI: 56-67) to 56.0 (95% CI: 51-62). Improvement in pain and function was sustained in patients available for postoperative follow-up.ConclusionIn this small, early follow-up series, we found that plantar condylectomy and surgical imbrication of the plantar plate to the metatarsal neck was modestly helpful to treat metatarsalgia and grade 0 plantar plate injuries.Level of evidenceLevel IV, retrospective case series.
