Summary
The Z-bunionectomy procedure demonstrates high patient satisfaction, with 90% reporting good to excellent outcomes. Long-term clinical and radiographic evaluations show positive results for bunion surgery patients.
Area of Science:
- Orthopedic Surgery
- Podiatry
- Foot and Ankle Reconstruction
Background:
- The Z-bunionectomy is a surgical technique used to correct hallux valgus (bunion).
- Assessing long-term outcomes is crucial for evaluating surgical efficacy and patient well-being.
Purpose of the Study:
- To evaluate long-term patient satisfaction and objective clinical outcomes following Z-bunionectomy.
- To correlate radiographic and functional findings with patient satisfaction after bunion surgery.
Main Methods:
- A retrospective review of 56 Z-bunionectomies in 31 patients with 5-9 years follow-up.
- Utilized a modified University of Maryland 100-Point Painful Foot Center Scoring System for patient satisfaction.
- Conducted clinical examinations and radiographic assessments, including range of motion and foot posture analysis.
Main Results:
- 90% of patients reported good to excellent satisfaction with the Z-bunionectomy.
- Mean radiographic measures showed corrected intermetatarsal angle (7.1°) and hallux abductus angle (8.96°).
- Objective findings revealed no pain or crepitus, good range of motion, and high purchase power on plantar paper testing.
Conclusions:
- The Z-bunionectomy procedure yields high long-term patient satisfaction and favorable objective clinical and radiographic results.
- No significant correlation was found between specific postoperative structural/functional features and patient satisfaction.
- The study supports the Z-bunionectomy as an effective surgical option for bunion correction.
