Summary
The HyProCure procedure effectively treats pediatric flexible flatfoot, improving foot scores and reducing pain. Proper implant depth is crucial for optimal outcomes, though sinus tarsi pain wasn't linked to specific risk factors.
Area of Science:
- Orthopedic Surgery
- Pediatric Orthopedics
- Foot and Ankle Surgery
Background:
- Subtalar arthroereisis (SA) is a common surgical approach for pediatric flexible flatfoot due to its success and safety.
- The HyProCure procedure is a newer SA technique with limited reported outcomes in pediatric cases.
Purpose of the Study:
- To evaluate the clinical and radiological results of the HyProCure procedure in pediatric flexible flatfoot.
- To identify risk factors associated with therapeutic outcomes and sinus tarsi pain following the HyProCure procedure.
Main Methods:
- A retrospective cohort study included 69 pediatric patients (107 feet) who underwent the HyProCure procedure between 2015 and 2020.
- Clinical outcomes (Maryland foot score, VAS) and radiological data were assessed at a minimum 1-year follow-up.
Main Results:
- Significant improvements were observed in VAS scores (preop: 4.06 vs. postop: 0.64) and MFS (preop: 71.36 vs. postop: 90.39).
- Radiographic parameters like T2MT angle and Meary's angle showed significant correction, while the Pitch angle increased.
- Inadequate implant depth was linked to lower MFS scores, but no risk factors for sinus tarsi pain were identified.
Conclusions:
- The HyProCure procedure demonstrates satisfactory clinical and radiological outcomes for pediatric flexible flatfoot with a low complication rate.
- Implant positioning, specifically the depth of the implant relative to the talar bisection line, is a critical factor influencing postoperative results.
