Flexor profundus lacerations in the distal part of zone I are usually treated by tendon reinsertion into bone. We present a modified technique in which three 'figure of eight' sutures include the palmar plate in the distal purchase. Inclusion of the palmar plate significantly strengthens the tensile strength of the repair and this was confirmed biomechanically in an experimental study. In a prospective clinical study, 15 patients with clean-cut complete lacerations of the profundus tendon in the distal part of zone I underwent the modified repair technique of three separate 'figure of eight' sutures with the palmar plate included in the suture distally and 7mm suture purchase proximally, with postoperative immediate active motion that ensured full active extension of the interphalangeal joints. There were no ruptures or infections. At final follow-up 12-25 weeks after surgery, the mean range of motion at the distal, proximal, and combined interphalangeal joints was 66 degrees, 100 degrees and 166 degrees respectively. All patients achieved an excellent or good outcome.
