Using a bone allograft to fixate proximal interphalangeal joint arthrodesis.

Unlabelled: Digital contractures are a very common deformity of the foot and ankle that require surgical correction. It has been shown that arthrodesis provides a better long-term result than arthroplasty of the interphalangeal joints. Arthroplasties usually require K-wire fixation that presents potential complications, such as pin tract infection. This study presents a new cadaveric bone matrix allograft to be used as rigid internal fixation for proximal interphalangeal joint arthrodesis. The purpose of using the allograft as a fixation device is to achieve solid bone fusion and avoid the potential complications of external pin fixation. Arthrodesis of the proximal interphalangeal joint was performed on 63 toes in 32 patients using TenFUSE (Solana Surgical, Memphis, TN), a sterile bone matrix allograft. The authors found 97% fusion rate with no complications reported to this date. It was concluded that this bone matrix allograft provides excellent results and is a suitable alternative fixation device for correction of hammer toe deformity.
