Great Toe Metatarsophalangeal Joint Arthroscopy: Simple Technique for Painful Nonunion.

ABSTRACT: Great toe metatarsophalangeal joint (MTPJ) arthroscopy was first described as a viable technique for a multitude of first MTPJ pathologies in the early 1970s; however, with improving arthroscopic technique and technology, these indications will continue to expand. Arthroscopy of the first MTPJ has increasingly become a new pursuit for foot and ankle specialists. Therefore, we have proposed a simple technique and illustration from our operating room setup to traction and to our procedural technique to make great toe arthroscopy simple and reproducible for arthroscopic foot and ankle surgeons.

Project description:BackgroundArthrodesis of the first metatarsophalangeal joint is the current treatment of choice for symptomatic advanced hallux rigidus and moderate-to-severe hallux valgus. There are different methods to perform arthrodesis, yet no consensus on the best approach. Therefore, this study aimed to determine the effects of preoperative and postoperative hallux valgus angle (HVA), joint preparation and fixation technique, and postoperative immobilization on the incidence of nonunion.MethodsA retrospective multicenter cohort study was performed that included 794 patients. Univariate and multiple logistic regression was conducted to determine associations between joint preparation, fixation techniques, postoperative immobilization, weightbearing, and pre- and postoperative HVA with nonunion.ResultsNonunion incidence was 15.2%, with 11.1% symptomatic and revised. Joint preparation using hand instruments (OR 3.75, CI 1.90-7.42) and convex/concave reamers (OR 2.80, CI 1.52-5.16) were associated with greater odds of a nonunion compared to planar cuts. Joint fixation with crossed screws was associated with greater odds of nonunion (OR 2.00, CI 1.11-3.42), as was greater preoperative HVA (OR 1.02, CI 1.00-1.03). However, the latter effect disappeared after inclusion of postoperative HVA in the model, with a small association identified between residual postoperative HVA and nonunion (OR 1.04, CI 1.01-1.08). Similarly, we found an association between odds of nonunion and higher body weight (OR 1.02, CI 1.01-1.04) but not of body mass index.ConclusionBased on our results, first metatarsophalangeal joint arthrodesis with planar cuts and fixation with a plate and interfragmentary screw is associated with the lowest odds of resulting in a nonunion. Higher body weight and greater preoperative HVA were associated with slight increase in rates of nonunion. It is crucial to properly correct the hallux valgus deformity during surgery.Level of evidenceLevel III, retrospective case control study.

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.
