Abstract
In moderate and severe Hallux Valgus metatarsus varus and incongruency of the joints are often important features. Basal osteotomy and distal soft tissue release can often achieve adequate correction of intermetatarsal angle (IMA) and joint alignment.. We retrospectively evaluated the results of Basal Osteotomy in 26 feet in 20 patients between January 1999 and December 2003. American Orthopaedics Foot & Ankle Society Score (AOFAS) was used for assessment. A subjective grading system was used to check patient’s satisfaction. The surgical technique consisted of crescentic basal osteotomy, lateral distal soft tissue release and medial capsular plication according to Roger Mann. Fourteen osteotomies were fixed with K wires that needed second operation to remove them. Barouk Screw was used to fix the osteotomy in 12 feet. Patients were mobilised in High heeled shoe postoperatively. Average age was 55.2 years and average follow-up was 25.8 months. The average preoperative Hallux Valgus Angle (HVA) and IMA were 37.38° and 17.27° respectively. At follow-up the HVA and IMA averaged 13.3° and 6.4° respectively. Sixteen feet had incongruent joint preoperatively that became congruent after surgery. In 25 feet sesamoid position improved after surgery. Average AOFAS score was 88.8. 94% patients were highly satisfied and graded their results as good to excellent. One patient had AOFAS score of < 50 due to her generalised poly-arthralgia and osteoporosis. K wire was broken across the TMT joint in one case and needed removal under GA. This lead to change of our practice as we started using Barouk screw to fix the osteotomy. Other complications consisted of decreased sensations over medial side of toe in three and mild metatarsalgia in one foot. Basal osteotomies with distal soft tissue release in the treatment of Hallux valgus give good correction of the deformity and high patient satisfaction. Barouk screw provides stable fixation.
