Abstract:
Background: Hallux rigidus is a common condition that leads to arthritis of the joint at the base of the big toe. It is the most common arthritic condition of the foot, affecting 1 in 40 people over the age of 50. Hallux rigidus tends to affect females more often than males and typically develops in adults over the age of 30.
Patients and methods: This is a double Cohort study assessing the results of treatment of end-stage hallux rigidus using 2 different surgical procedures Modified Keller Interposition Arthroplasty and first Metatarsophalangeal Joint arthrodesis. A total of 40 patients (22 females and 18 males) were enrolled in the present study and underwent 20 arthrodesis, and 20 resectional arthroplasty procedures.
Results: Assessment was done according to pain, function, and alignment, as well as objective radiographic and physical findings,. The average follow-up period was 22.16 +/- SD months (range, 12 to 36).. No statistically significant difference was found in age or the number of subjects included in the 2 treatment groups (p ¼ .11 and p ¼ .16, respectively). The body mass index was not significantly indifferent among the 2 treatment groups,. No statistically significant difference was found in the subjective outcomes among the two treatment groups using the American College of Foot and Ankle Surgeons’ First Metatarsophalangeal Joint and First Ray Scoring Scale (patient questionnaire) or the modified Hallux Metatarsophalangeal-Interphalangeal Scale of the American Orthopedic Foot and Ankle Society (p ¼ .64 and p ¼ .14, respectively). Furthermore, the correlation coefficient between the 2 subjective scoring scales was 0.7, statistically significant and reflecting a moderate to high correlation (p < .001). The results of the radiographic and clinical evaluation revealed that metatarsalgia was the most common finding for the arthrodesis group (15%), and floating hallux for the resectional arthroplasty group (30%).
Conclusion: There is no significant difference in the results of our study, the two surgical procedures are viable options for the treatment of end-stage hallux rigidus.
