Juncturae Tendinum Transfer for Extensor Tendon Reconstruction: A Case Report.

CASE: A 9-year-old girl, with a history of crush injury to her right hand 2 years ago, presented with inability to extend her index finger. Exploration revealed segmental loss of extensor tendons to the index finger with a pre-existing scar in the route of tendon transfer. The juncturae tendinum (JT) between extensor digitorum communis of the middle and ring fingers (Von Schroeder -3y) was transferred to reconstruct the extensor tendon. At 1-year follow-up, finger extension was restored, with improved grasp and release.

CONCLUSION

JT transfer could prove useful in reconstructing zone II extensor tendon injuries with scarring and fibrosis in the route of conventional tendon transfer/graft.
