• BACKGROUND
    • Jones fractures remain a challenging treatment entity in orthopaedics. Biomechanical stresses, including increased fifth metatarsal (5MT) lateral angle deviation (MLAD), are associated with increased fracture and refracture rates. Current fixation techniques produce good outcomes; however, they do not address metatarsal morphology, which can predispose to refracture. This study describes a novel surgical technique and case series utilizing intramedullary screw fixation and distal metatarsal corrective osteotomy for the management of Jones fractures.
  • METHODS
    • A retrospective case series was undertaken, including 22 consecutive Jones fracture patients operated on by a single surgeon. Patient demographics, imaging, and operative information were obtained, with return to sport/previous function and radiological outcomes, including fracture union being the outcomes of interest. The surgical technique utilizes a distal osteotomy of the 5MT followed by retrograde guidewire and drilling utilizing the osteotomy. A cannulated screw is passed antegrade along the entire length of the 5MT with manual MLAD correction. Autograft or bone substitute (Augment) was then injected at the fracture site.
  • RESULTS
    • Median age was 30 years (Q1, Q3: 18, 49 years). Median time from injury to operation was 13 weeks (Q1, Q3: 9, 30 weeks), and clinical follow-up period was 37 months (Q1, Q3: 14, 74 months). Radiological union was achieved at a median of 12 weeks (Q1, Q3: 8, 15 weeks) with clinical union at 11 weeks (Q1, Q3: 8, 14 weeks). All but one patient returned to preinjury functional levels, including 6 professional athletes who returned to preinjury national competition. No refractures were identified.
  • CONCLUSION
    • The technique described in this study is a viable and safe means of managing Jones fractures. The technique may be particularly useful in patients with excessive MLAD.
  • LEVELS OF EVIDENCE
    • Level IV: Retrospective case series.
