Summary
This summary is machine-generated.

Minimally invasive surgery (MIS) and open first ray dorsiflexion osteotomy (DFO) show similar early healing and complication rates. Both techniques effectively correct first ray alignment without significant differences in outcomes.

Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Surgery
  • Surgical Innovation

Background:

  • Limited comparative literature exists for open versus minimally invasive surgery (MIS) techniques in first ray dorsiflexion osteotomy (DFO).
  • This study addresses this gap by comparing early healing and complication rates between MIS and open first ray DFO.

Purpose of the Study:

  • To compare the early healing and complication rates of minimally invasive surgery (MIS) versus open first ray dorsiflexion osteotomy (DFO).
  • To evaluate the efficacy of MIS DFO in correcting first ray alignment compared to the open approach.

Main Methods:

  • Retrospective cohort review of 28 patients undergoing first ray DFO (2015-2024).
  • Data collected included demographic factors, comorbidities, radiologic parameters, and healing outcomes.
  • Comparison between 13 open and 15 MIS procedures.

Main Results:

  • All osteotomies healed with no wound or infection complications in both groups.
  • No significant difference in hardware removal rates (7.7% open vs. 6.7% MIS).
  • Comparable correction of the lateral Meary angle (10.5° ± 3.9° open vs. 9.7° ± 4.3° MIS) and dorsal closing wedge resection (3.5 mm open vs. 4.1 mm MIS).

Conclusions:

  • MIS and open first ray DFO demonstrate similar short-term healing and complication profiles.
  • The MIS technique shows comparable efficacy to open surgery for correcting first ray alignment.
  • Further research is warranted to assess long-term outcomes of MIS first ray DFO.
