| Summary: | 【Abstract】Objective: Interphalangeal joint con-tracture is a challenging complication of hand trauma, which
reduces the functional capacity of the entire hand. In this
study we evaluated the results of soft tissue distraction
with no collateral ligament transection or volar plate removal
in comparison with traditional operation of contracture re-lease and partial ligament transection and volar plate
removal.
Methods: In this prospective study, a total of 40 pa-tients in two equal groups (A and B) were studied. Patients
suffering from chronic flexion contracture of abrasive trau-matic nature were included. Group A were treated by soft
tissue distraction using pentagonal frame technique and in
Group B the contracture release was followed by finger
splinting.
Results: Analyzed data revealed a significant differ-ence between the two groups for range of motion in the
proximal interphalangeal joints (P<0.05), while it was not
meaningful in the distal interphalangeal joints (P>0.05). There
was not a significant difference in the degrees of flexion
contracture between groups (P>0.05). Regression analysis
showed that using pentagonal frame technique significantly
increased the mean improvement in range of motion of proxi-mal interphalangeal joints (P<0.001), while the higher the
preoperative flexion contracture was observed in proximal
interphalangeal joints, the lower improvement was achieved
in range of motion of proximal interphalangeal joints after
intervention (P<0.001).
Conclusion: Soft tissue distraction using pentagonal
frame technique with gradual and continuous collateral liga-ment and surrounding joint tissues distraction combined
with skin Z-plasty significantly improves the range of mo-tion in patients with chronic traumatic flexion deformity of
proximal and/or distal interphalangeal joints.
