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.
