Abstract:
OBJECTIVE:To explore the effectiveness of QIN Sihe's surgical strategy combined with Ilizarov technique in treating foot and ankle deformities on the verge of amputation.
METHODS:A retrospective analysis was conducted on the clinical data of 56 patients (62 feet) with foot and ankle deformities on the verge of amputation treated with QIN Sihe's surgical strategy and Ilizarov technique between May 2010 and December 2020. Among them, there were 39 males and 17 females. The age ranged from 8 to 62 years (median, 27.5 years). QIN Sihe's surgical strategy: subcutaneous release or open lengthening of contracted Achilles tendons, limited correction of bony deformities through multiple osteotomies during surgery, tendon transfer to balance the power of the foot and ankle, simultaneous percutaneous osteotomy and correction of tibial torsion deformity to restore the weight-bearing line of the lower extremity, and installation of Ilizarov foot and ankle distraction devices for slow distraction and correction of residual foot and ankle deformities. After removal of external fixation, individualized braces were used for protection during exercise and walking. For patients with bilateral deformities, staged surgeries were performed. The effectiveness was evaluated according to the QIN Sihe's Postoperative Evaluation Criteria for Lower Limb (Foot and Ankle) Deformity Correction and Functional Reconstruction at last follow-up.
RESULTS:All patients achieved the preoperative expected orthopedic and functional reconstruction goals. The postoperative wearing time of external fixator was 3-7 months, with an average of 5.5 months. The incidence of pin tract infection during the treatment period was 6.5% (4/62). All patients were followed up 25-132 months (median, 42 months). All 56 patients successfully retained their limbs. At last follow-up, foot and ankle deformities were corrected, the weight-bearing line was basically restored, and plantigrade feet were restored. At last follow-up, according to QIN Sihe's Postoperative Evaluation Criteria for Lower Limb (Foot and Ankle) Deformity Correction and Functional Reconstruction, the effectiveness was rated as excellent in 37 cases (39 feet), good in 18 cases (21 feet), and fair in 1 case (2 feet). The excellent and good rate was 96.8% (60/62).
CONCLUSION:The combination of QIN Sihe's surgical strategy and Ilizarov technique in treating foot and ankle deformities on verge of amputation is minimally invasive, safe, and the therapeutic effect is controllable. This combined approach has unique advantages in preserving limb function and restoring biomechanical balance.
