Emergency brake response time after first metatarsal osteotomy

Area of Science:

• Orthopedic surgery
• Biomechanics
• Patient outcomes

Background:

• Limited data exists on return-to-activity timelines post-foot surgery.
• First metatarsal osteotomy is a common procedure for hallux valgus.
• Assessing functional recovery is crucial for patient guidance.

Purpose of the Study:

• To evaluate if six weeks is sufficient for emergency brake response time to recover after first metatarsal osteotomy.
• To compare postoperative brake response times to preoperative levels and a healthy control group.

Main Methods:

• Prospective observational study of 28 patients undergoing first metatarsal osteotomy.
• Utilized a custom driving simulator to measure total brake response time, reaction time, and brake time.
• Preoperative and 2-week/6-week postoperative assessments, with a matched control group.

Main Results:

• Patients showed significant improvement in all braking metrics by six weeks post-surgery.
• Only 7/28 patients could complete the 2-week assessment due to pain.
• At six weeks, braking times were comparable to the healthy control group.

Conclusions:

• Emergency braking performance returns to preoperative levels by six weeks after first metatarsal osteotomy.
• Six weeks appears to be an adequate recovery period for this specific functional outcome.
• Further research can guide return-to-activity recommendations for foot surgery patients.
