A Prospective Study of Distal Metatarsal Chevron Osteotomies with K-Wire Fixations to Treat Hallux Valgus Deformities

Abstract

IntroductionHallux valgus is one of the most common forefoot deformities worldwide. Females are affected more often than males. The three most common clinical symptoms are the painful bunion, transfer metatarsalgia, and hammer or claw toes.MethodsThis case series consisted of 20 patients who had chevron osteotomy from January 2015 to January 2016. The clinical assessment was measured by The American Orthopedic Foot and Ankle Score (AOFAS), and radiologic assessment was determined by preoperative and postoperative hallux valgus angle (HVA) and intermetatarsal angle (IMA).ResultsThe patients’ mean age was 56 years. Out of 20 patients, 19 were female, and one was male. The mean AOFAS improved from 51 preoperatively to 82 postoperatively. The HVA improved from 26° preoperatively to 14°. There were five complications including four Kirschner (K)-wire complications.ConclusionDistal chevron osteotomy is a reliable and time-tested procedure. The K-wire fixation has a relatively high complication rate. We planned to use other methods of fixation and then compared them with K-wires fixation results for future studies.

Incidence and Risk Factors for Pin Site Infection of Exposed Kirschner Wires Following Elective Forefoot Surgery

“…In this study, there were no significant differences in outcomes based on the duration of K-wire fixation. Baig et al 1 reported on 20 patients undergoing chevron osteotomies with K-wire fixation for hallux valgus deformity and noted a 20% complication rate with 2 patients having K-wire migration greater than 1.5 cm and 2 patients with pin site infections requiring a 5-day course of antibiotics.…”

An Unusual Presentation of Osteochondroma in a Sexagenarian

“…Osteochondromas usually present during the patients' first three decades of life with no predilection for sex [ 6 ]. Symptoms depend on the osteochondroma’s size and location; most cases are asymptomatic and painless [ 7 - 8 ]. If symptoms manifest, they are usually characterized by bulging, swelling, and pain with mechanical compression on adjacent anatomical structures.…”

Improving Management of Paediatric Buckle Fracture in Orthopaedic Outpatients: A Completed Audit Loop

“…Implementing the NICE guidelines significantly decreased the number of visits and reduced the workload on fracture clinics which are often overbooked; the doctors are tired from the work and patients are tired due to long wait times [3-4]. While the reduction in visits is relatively small, this demonstrated that smarter and more practical approaches could help control and manage clinical numbers.…”
