- Abstract:
- Introduction: The aim of this study was to evaluate long-term results in function and health-related quality of life (HRQOL) in patients with Hallux rigidus (HR) after Hemi-CAP® implantation. Material and Methods: A total of 14 patients with HR were operated between 2007 and 2009 at the department of orthopaedic surgery of the Medical University of Graz. At the follow-up (FU) postoperative function was scored according to American Orthopaedic Foot and Ankle Society scale (AOFAS) for 1st Forefoot Ray, Foot and Ankle Disability Index Score (FADI), Foot and Ankle Outcome Score (FAOS) and Foot and Ankle Outcomes Questionnaire (FAOQ). For HRQOL assessment the Short-form 36 health survey (SF-36) and EQ-5D-3L were used. Pre- and postoperative pain were determined by visual analogue scale (VAS); pre- and postoperative range of motion (ROM) were compared. Patients were asked about their general satisfaction with the implant. Results: The current study included eleven patients with a mean postoperative FU of 105.0 ± 5.3 months. Mean score for AOFAS was 84.4 ± 10.4, for FADI 94.8 ± 8.5, for Foot and Ankle Scale in FAOQ 95.7 ± 7.6, for Shoe Comfort Scale in FAOQ 67.3 ± 16.2. The mean score for pain in FAOS was 90.2 ± 19.9; mean score for symptoms was 93.5 ± 15.3; mean score for activities of daily life (ADL) was 96.9 ± 7.7; mean score for sports and recreation (sport, recr.) in FAOS was 90.0 ± 17.7; mean score for quality of life (QOL) 86.9 ± 17.1. There were no statistically significant differences in HRQOL between the hemiarthroplasty group and a sex- and age-matched Austrian normal population. Mean VAS pain score improved significantly from 8.1 ± 1.0 preoperatively to 1.3 ± 2.0 postoperatively (p .003). Mean total ROM of the First metatarsophalangeal joint (FMTPJ) improved from a preoperative 28.5 ± 13.8 degrees to a postoperative 40.6 ± 16.5 degrees (p .098). The clinical outcome was considered very satisfactory by nine out of eleven patients. Discussion: Our results show that Hemi-CAP® is a useful therapy option for patients, with good functional outcomes after almost 10 years of FU.
