Background:
Recurrence rate of surgical treatment of hallux valgus ranges in the literature from 2.7% to 16%, regardless of used procedure. In this study, long-term results of a minimally invasive distal osteotomy of the first metatarsal bone for treatment of recurrent hallux valgus are described.
Methods:
32 consecutive percutaneous distal osteotomies of the first metatarsal were performed in 26 patients for treatment of recurrent hallux valgus. Primary surgery had been soft tissue procedures in 8 cases (25%), first metatarsal or phalangeal osteotomies in 19 cases (59.4%) and Keller procedures in 5 cases (15.6%).
Results:
Patients were assessed with a mean follow-up of 9.8±4.3 years. All patients reported the disappearance or reduction of the pain. The mean overall AOFAS score improved from 46.9±17.8 points to 85.2±14.9 at final follow-up. The mean hallux valgus angle decreased from 26.1±9.1 to 9.7±5.4°, the intermetatarsal angle decreased from 11.5±4.5 to 6.7±4.0°. No major complications were recorded with a re-recurrence rate of 3.1% (1 case).
Conclusions:
Percutaneous distal osteotomy of the first metatarsal can be a reliable and safe surgical option in the recurrent hallux valgus with low complication rate and the advantages of a minimally invasive surgery.

IV, Retrospective Case Series.

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
