[Reconstruction of the traumatically amputated thumb by continuous Matev distraction. Experiences and results in 48 cases].

Continuous distraction can be considered as an alternative method of thumb reconstruction after traumatic loss. This technique is applicable if at least two thirds of the metacarpal length are retained and the stump is well covered by soft tissue. Elongation up to 100% of the initial length is then realizable. For a good functional precision grip it is necessary for the reconstructed thumb to reach the nail root of the opposite side. There is normal tactile gnosis after distraction. The strength of power grip is not decreased. Impaired, however, is the skillfulness of pulp-to-pulp pinch. We report on our experience in 48 cases.
