Efficacy of outpatient bilateral simultaneous hallux valgus surgery

Bilateral simultaneous hallux valgus correction is traditionally performed as an inpatient procedure due to concerns regarding adequate postoperative analgesia and difficulty mobilizing. We prospectively evaluated 40 consecutive patients (80 feet) who underwent outpatient surgical correction of bilateral symptomatic hallux valgus. Patients underwent preoperative radiological and clinical assessment using pain and American Orthopaedic Foot & Ankle Society (AOFAS) hallux assessment scores. Patients underwent preoperative counseling and were assessed for medical suitability for outpatient surgery. They were instructed to have responsible adult caregivers available for 24 hours postoperatively, easy access to after-hours emergency medical care, and access to a telephone. Procedures were performed under general anesthesia with local anesthetic ankle block. Postoperatively, patients were discharged after assessment by medical, nursing, and physiotherapy staff with an oral analgesia regimen. Cast immobilization was not used. Patients were reviewed at 6 weeks and 3 months postoperatively with repeated clinical and radiological assessment. All patients were discharged home and none required inpatient ward admission. Post-discharge, no patient presented to the emergency department or their general practitioner as a consequence of poor pain control. At final follow-up assessment, mean AOFAS hallux scores had improved from 58.1 (range, 29-80) to 89.0 (range, 47-100) (P<.001). The mean hallux valgus angle improved from 33.2 degrees (range, 15 degrees -53 degrees) to 16.9 degrees (range, 3 degrees -39 degrees) and the intermetatarsal angle had improved from 13.2 degrees (range, 6 degrees -23 degrees) to 8.5 degrees (range, 4 degrees -15 degrees) (P<.001). Eighty-five percent of patients reported that they would recommend outpatient surgery. Bilateral hallux valgus surgery can be performed safely as an outpatient procedure in selected patients with acceptable levels of patient satisfaction.
