MODIFIED SILVER’S MCBRIDE PROCEDURE. A SOFT TISSUE PROCEDURE FOR HALLUX VALGUS

Arrowe Park Hospital, Arrowe Park Road, Upton, Wirral L49 5PE

The aim of the study was to assess the clinical, radiological and paedobarographic outcome following modified Silver’s McBride’s procedure, in the treatment of Hallux Valgus. Between 1997 and 1999, Modified Silver’s McBrides procedure for Hallux Valgus was performed on 38 foot in 28 patients (18 unilateral and 10 bilateral). The median age was 60 years. The median follow up was 26 weeks. Clinical outcome measures consisted of pain, deformity, mobility, walking ability and shoe wear. Radiological outcome measures were Hallux Valgus angle, Intermetatarsal angle, 1st to 5th Metatarsal distance, 1st to 2nd metatarsal distance, and the DMAA (Distal Metatarsal Articular Angle). Paedobarographic (Musgrave) outcome of peak pressure, total force, time from heel strike to toe lift off post operatively were analysed. Preoperative visual analogue pain score was 5–8 and 0–4 postoperatively (p<0.001). 34 feet had pain on walking preoperatively and only 11 had pain post-operatively. 12 were wearing special shoes pre- operatively and 5 post-operatively. Hallux Valgus angle was 34 pre-operatively and 19 post-operatively (p<0.001). IMT angle was 14.53 pre-op and 10.88 postop (p<0.001). 1st-5th MT distance was 67mm pre- op and 63mm post-op (p=0.001). 1st-2nd MT distance was 15 pre-op and 10 post-op (p=0.004). DMAA was 24.7 degrees. 21 foot an obliquity of the 1st tarsometatarsal joint was seen indicating an anatomical cause of metatarsus varus. Foot pressure studies showed a peak pressure of 1.37kg/cm2 , heel to toe off- time was 936.9ms and maximum load was 65.2 kg. There were 3 cases of superficial wound problems. One patient developed Hallux varus deformity, with no functional disability.

Conclusion: Modified Silver’s McBride procedure for the treatment of Hallux Valgus is a soft tissue procedure and is a safe alternative to the commonly practiced osteotomies for correction of this disorder.
