Evaluation of reversal osteofixation using K-wires in digital replantation.
2014
Introduction. Modified, reversal technique of fixation in digital
replantation using K-wires was analyzed. The results obtained from the
standard technique and reversal technique of fixation using K-wires were
compared. Objective. The aim was to compare the results of osteofixation
using K-wires in digital replantation when either standard or reversal,
modified technique was used. Methods. A retrospective study included 103
replanted fingers in 72 patients. The first group included standard fixation
using K-wires and the second group included fixation using K-wires, but with
a modified technique. Modification consisted of the opposite order of moves
during the phalanges fixation compared to the standard technique: first,
K-wire was introduced intramedullary in the proximal phalanx and the top of
the wire was drawn out through the skin in proximal part of the finger or
hand. Second, distal part of the wire was introduced in the phalanx of the
amputated part of the finger intramedullary until the wire entered the
cortex. Results. Duration of bone healing after digital replantation was
shorter in cases where reversal technique was used in comparison with
standard technique (7.2 weeks compared to 7.5 weeks). Conclusion. The
comparison of standard and reversal technique of phalangeal fixation with
K-wires in digital replantation shows that both techniques are useful.
Reversal technique expands the choice of operative techniques for bone
fixation during the replantation. It shows some advantages and enables
avoidance of vein injuries. [Projekat Ministarstva nauke Republike Srbije,
