title: Palmaris Longus Tendon Grafting for Extensor Pollicis Longus Tendon Rupture bScrew Tip after 20 years.
abstract: BACKGROUND
  Spontaneous ruptures of extension pollicis longus tendon predominantly occur after undisplaced or minimally displaced distal radial fracture near Lister tubercle. Systemic inflammatory diseases and systemic or local steroid, mechanical causes like bony ridges, presence of bone plate or external fixator pin may precipitate this. Repetitive uses in certain occupation like cooking, cow milking, tailoring and direct trauma in kick boxer are also identified as cause. In this study it is caused by screw tip that also after 20 years. Instead of tendon transfer, interposition tendon grafting is preferred.
  A 36-year-old male manual worker was plated for distal radial shaft fracture of left side. Distal most screw length was 3 mm in excess. After 20 years he developed rupture of extensor pollicislongus spontaneously. After excluding probable other causes and confirming by USG tendon ends were explored through dorsal incision. Offending slotted head screw was removed using hollow mill. Ipsilateral Palmaris longus tendon was grafted. Tension was set by extension of thumb and neutral position of the wrist. Removal of stitch after 2 weeks, short arm cast immobilization for 6 week and intermittent splinting and exercises for another 6 weeks yield excellent result.
  
  
  CONCLUSIONS
  Timely removal of implant when it is applied over tendon rich areas is preferable. In late situation surgeon should be equipped and careful to remove it. To avoid chance of transferring a diseased tendon interposition grafting using Palmaris longus is justified.
