[The problem of immobilization following tenosuture--an experimental study]

The course of repair of the transected and afterwards once more sutured tendines were observed at the superficial flexor tendines of the toes of the pelvis extremity in 46 adult rabbits by experimental investigations on condition of free mobility, of immobilisation with maintained muscular tension, and of immobilisation with excluded muscular tension. The macroscopic, microscopic, and mechanical control investigations showed the greatest mechanical density and the smallest connective-tissue proliferation to the environment after tenosuture by immobilisation with excluded muscular tension for 2-3 weeks and following immobilisation with maintained muscular tension up to the 6th week. The unique tenosuture without immobilisation showed minimum load capacity and heavy adhesions with the environment. The results were placed between these both groups after tenosuture by immobilisation with maintained muscular tension from the first.
