Summary
Background: Hallux valgus (HV) is one of the most frequent pathologies of the forefoot. Diagnosis and treatment depend on several factors. To evaluate patients with HV measurements of hallux valgus angle (HVA) and intermetatarsal angle (IMA) by traditional midaxial method are the most common strategies used nowadays. Therefore, it is important to study interreader reliability (IRR) of both angles on pre- and post-operative.
Purpose: Determine intrareader and interreader reliability of HVA and IMA both pre-operative and postoperative.
Methods: A sample of 48 patients (55 feet) was selected from the patients above the age of 18 years, with hallux valgus, who underwent osteotomy of the first metatarsal in an orthopedics’ department. All had weight-bearing pre-operative and post-operative anterior-posterior (AP) and lateral X-rays performed. Three readers measured HVA and IMA both pre-operative and post-operative using the traditional midaxial method. To ensure the uniformity of the measurement technique the 3 readers evaluated eight training cases together. All readers repeated 20% of the measurements after one week. Intraclass Correlation Coefficient (ICC) were obtained.
Results: For IMA pre- and post-operative ICC were .779 and .773, respectively. For HVA pre- and postoperative ICC were .798 and .932. Standard error of measurement was considerably below mean values for both angles on both moments. Intrareader reliability results showed very high reliability.
Conclusions: IRR was high (>.700) for both HVA and IMA on pre-operative and post-operative. However, results showed an advantage of HVA when compared with IMA, considering higher IRR and better precision of the estimates
