Abstract

The authors, in their experiments on chickens, imitate human 'no man's land' flexor tendon injuries of bad prognosis. For reconstruction of gliding surfaces they transplanted composite flexor tendon grafts containing flexor tendons with their sheath, pulleys, and vincula. Autologous grafts were compared with homologous composite tendon grafts preserved in β-propiolacton. Summarizing the results of macroscopic and light microscopic examinations they state that the tendon sheath of the autologous composite tendon grafts revitalize in two weeks, and their tissue structure remains practically intact. The composite tendon allografts conserved in β-propiolacton on the contrary rebuild much more slowly, on the average over three months. Regeneration is accompanied by round-cell infiltration. In the case of the autogenous graft generally smaller, and in the case of homologous composite flexor tendon graft more multitudinous adhesions occurred between flexor tendon and tendon sheath. The authors conclude from the literature and their own results that the reconstruction of flexor tendons with autologous composite flexor tendon grafts is a proper method for the restoration of severe flexor tendon injuries. Before clinical use, homologous composite flexor tendon grafts require more experimental investigation.
