Preserved tendon grafts in reconstructive hand surgery: a review

The authors discuss the use of tendon grafts, primarily in flexor tendon repair, a problem not yet satisfactorily resolved. Criteria for successful non-autogenous tendon grafts are presented, with interest focussing on the immunologic antigenicity of the grafts and the physiologic properties and processes of tendon regeneration. Methods for preserving tendon grafts, including freeze-drying and the use of various chemical agents, are compared and recommended, as well as methods for managing tendon grafting procedures. Questions remaining to be answered in the area of preserved tendon grafts are raised, with suggestions for some answers and avenues for future research. Possibilities for wider clinical applications of the procedure are supported and discussed as well.
