Minimally invasive calcaneal osteotomy (MICO) offers a shorter operation time and smaller incision compared to open techniques. Clinical outcomes were similar between MICO and open calcaneal osteotomy in this study.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Surgery
Background:
- Calcaneal osteotomies are frequently used to correct hindfoot deformities.
- Minimally invasive techniques (MICO) are emerging with promising results.
- Direct comparison of intraoperative parameters between open and MICO calcaneal osteotomy is lacking.
Purpose of the Study:
- To prospectively compare intraoperative parameters of open versus minimally invasive (MICO) calcaneal osteotomy.
- To evaluate clinical and radiological outcomes at 6 and 12 weeks postoperatively.
Main Methods:
- A prospective study included 60 patients undergoing calcaneal osteotomy (33 open, 27 MICO) with a minimum 12-week follow-up.
- Intraoperative parameters recorded: operation time, fluoroscopy time, fluoroscopy dose, and skin incision length.
- Clinical (FAOS) and radiological outcomes assessed postoperatively; statistical analysis using Wilcoxon test.
Main Results:
- MICO group demonstrated significantly shorter operation times.
- Skin incision length was significantly shorter in the MICO group.
- No significant differences were found in fluoroscopy time, radiation dose, clinical outcomes (FAOS), or radiological follow-up between groups.
Conclusions:
- Minimally invasive calcaneal osteotomy (MICO) results in significantly reduced operating time and incision length.
- Radiation exposure and clinical outcomes were comparable between MICO and open techniques.
- Shorter operating time in MICO calcaneal osteotomy is considered a beneficial factor.
