In claw toe deformity, the plantar plate of the metarsophalangeal joint becomes displaced onto the dorsal aspect of the metatarsal head. The Stainsby procedure replaces the displaced plantar plate to its correct position beneath the metatarsal head.
In this study we assess the efficacy of a modified Stainsby procedure for the treatment of claw toe deformity.
Thirteen patients were operated on between 2002 and 2008. Eleven patients (13 feet) were available for review with the average follow-up period being 16 months. Clinical examination was performed and AOFAS forefoot scores were measured.
All 13 (100%) of the feet operated on had severe or moderate pain preoperatively. None had significant pain at review. Plantar callosities were reduced from 13 (100%) feet preoperatively to 1 (9%) foot postoperatively. The AOFAS forefoot score in the eleven patients improved significantly by 40.7 points from a preoperative mean of 20.1 to a mean of 50.2 at review (p<0.001). Ten (91%) of the 11 patients were completely satisfied with the procedure, 1 patient was satisfied with some reservations.
This study demonstrates the modified Stainsby procedure to be effective in correcting claw toe deformity in the rheumatoid patient. It relieves pain, skin callosities and improves overall forefoot function.
