Summary
Simultaneous bilateral surgery for accessory navicular bone is as effective as unilateral surgery. This study found no significant differences in recovery times or clinical outcomes, suggesting bilateral procedures may be a viable option.
Area of Science:
- Orthopedic Surgery
- Podiatric Medicine
- Sports Medicine
Background:
- Accessory navicular bone, particularly type II, frequently occurs bilaterally.
- Unilateral surgical correction is more common than simultaneous bilateral surgery, despite bilateral presentation.
Purpose of the Study:
- To compare clinical outcomes between unilateral and simultaneous bilateral surgical resection of type II symptomatic accessory navicular.
- To evaluate the impact of surgical approach on recovery timelines and patient-reported outcomes.
Main Methods:
- Retrospective study of 26 patients (42 feet) undergoing accessory navicular resection between 2018-2022.
- Patients divided into unilateral (Uni) and bilateral (Bi) surgery groups.
- Comparison of time to walking, jogging, return to athletics, and postoperative SAFE-Q scores; age-stratified analysis performed.
Main Results:
- No significant differences found between Uni and Bi groups in time to walking, jogging, or full athletic activity.
- Postoperative SAFE-Q scores showed no statistically significant differences between the surgical groups.
- Age-stratified analysis (cutoffs at 16, 15, and 19 years) revealed no significant differences between unilateral and bilateral surgery outcomes.
Conclusions:
- Simultaneous bilateral surgery for type II symptomatic accessory navicular does not appear to delay recovery compared to unilateral surgery.
- Bilateral simultaneous surgery may be considered without hesitation, regardless of patient age.
- Further research could explore long-term outcomes and patient satisfaction across different surgical approaches.
