[Prognostic evaluation of reconstructive surgery of the flexor tendons in the "no man's land" of the hand. Factors affecting the final results].

For flexor tendon lacerations in "no man's land" of the hand the author has developed a preoperative classification system for predicting functional results which is an extension of the work of Boyes and Buck-Gramcko. On the basis of a review of the literature as well as his own experience, the author found that the prognosis after secondary reconstructive procedures depends above all on the age of the patient, the interval between injury and surgery, the nature and severity of the injury and the associated injuries. After considering these factors, a point system was developed by which very good, good, satisfactory, and poor results could be predicted. In this way, a standardized and moderate surgical approach can be developed and an exact evaluation and comparison of results can be instituted, Since a system for predicting of functional results has been developed, it is recommended that this system be adapted to help identify improved surgical methods of handling certain severe tendon injuries.
