    A novel Z-osteotomy procedure for hallux valgus correction shows high patient and surgeon satisfaction. This technique utilizes rigid internal fixation for effective first metatarsal realignment.

    Area of Science:

    • Orthopedic Surgery
    • Podiatric Medicine
    • Skeletal Biomechanics

    Background:

    • Hallux valgus, a common foot deformity, often requires surgical intervention.
    • Existing surgical techniques for hallux valgus may have variable outcomes and patient satisfaction rates.

    Purpose of the Study:

    • To evaluate the efficacy and patient/surgeon satisfaction of a new Z-osteotomy procedure for hallux valgus correction.
    • To assess the long-term outcomes of this novel surgical technique.

    Main Methods:

    • A horizontally directed displacement Z-osteotomy was performed on the first metatarsal in 39 patients (66 feet).
    • Rigid internal fixation was achieved using 3.5 or 2.7-mm bone screws.
    • Follow-up averaged 29 months (range: 24-32 months).

    Main Results:

    • The procedure demonstrated a surgeon satisfaction rate of 79%.
    • Patient satisfaction rate was notably high at 85% for complete satisfaction.
    • The technique involves precise realignment of the first metatarsal bone.

    Conclusions:

    • The described Z-osteotomy with rigid internal fixation is an effective and well-tolerated procedure for hallux valgus correction.
    • High patient and surgeon satisfaction rates suggest this technique is a favorable option for hallux valgus treatment.
