Digital contracture deformity after implantation of a silicone prosthesis: light and electron microscopic study.
Following the implantation of a silicone tendon prosthesis for reconstruction of a deep flexor tendon, an extensive, dense, contractile fibrosis developed rapidly. The resulting flexion deformity ultimately necessitated an amputation. The amputated specimen was examined by light and electron microscopy. A great many myofibroblasts were seen in the new tendon sheath, which, because of their contractile properties, probably caused the deformity.
