Abstract

Category: Midfoot/Forefoot, Trauma Introduction/Purpose: Several controversies persist regarding fracture treatment of the fifth metatarsal base. Due to its low blood supply, Jones fracture has an inherent difficulty of consolidation, and may devolop complications such as delayed union, non- union and refracture. Usually the Jones fracture treatment is done with extended period of non-weightbearing with either nonoperative or operative treatment. The surgery is indicated particularly in athletes or in the setting of nonunion or fracture displacement. The purpose of the present retrospective case series is to assess postoperative outcomes among patients who weight bear earlier than standard practice. Methods: We performed a retrospective analysis of the medical and radiographic records from patients who had undergone operative IM fixation of an acute isolated Jones fracture from May 2013 and August 2018. Patients were permitted to weight- bear as tolerated. Demographic information, such as age, gender, body mass index, the use of tobacco, presence of medical comorbidities, and the time of radiographic union were evaluated. Standardized radiographs at 2 weeks, 6 weeks, 3 months and 6 months after surgeries were chosen for evaluation. Radiographic union was defined as bridging in 2 of 3 (medial, lateral, plantar) cortices. Results: Twenty one patients were included for analysis. Of these, 14 had at least one comorbidity present at time of operation. Average BMI was 37.6, and average age was 44.8. One patient (4.8%) was lost to follow up, and therefore did not have radiographic results available for review at any appointment. At 6 weeks, 16 of 21 patients showed signs of radiographic healing; 8 were completely healed, and 8 were incomplete. One patient (4.8%) had nonunion, which was documented at 6 week, 3 month, and 6 month readings. None of the 21 patients experienced any other postoperative complications, including infection, wound dehiscence, sepsis, DVT, implant failure, or need for revision surgery. Conclusion: Patients who were subjected to early weight-bearing after fifth metatarsal Jones fracture surgery had satisfactory fusion rates with no additional postoperative complications, even despite having high average BMI and multiple comorbidities. We believe that patients can be treated with early weightbearing as tolerated after operative fixation of an acute Jones fracture, and achieve satisfactory outcomes comparable those associated with traditional postoperative protocols.
