title: [Ligament reconstruction for the chronic instability of the traumatic thumb carpometacarpal joint].
abstract: OBJECTIVE
  We evaluated the results of ligament reconstruction performed for chronic instability of the traumatic thumb carpometacarpal joint.
  
  
  METHODS
  Seven male patients with traumatic instability of the thumb carpometacarpal joint underwent ligament reconstruction with the use of the technique described by Eaton and Littler. The mean duration between the traumatic event and the operation was eight months. According to the radiological criteria by Eaton and Littler, five patients had stage I, and two patients had stage II disease. The mean follow-up period was 23 months. The results were assessed according to the criteria by Lane and Eaton.
  
  
  RESULTS
  Postoperatively, the patients' grip strength and pinch strength increased by a mean of 40.4% (range 31% to 50%) and 75.4% (range 62% to 100%), respectively. No increases in the extent of arthrosis were observed in the carpometacarpal joint during the follow-up period. None of the patients developed morbidity associated with the functions of the flexor carpi radialis and the wrist. The results were excellent in four, and good in three patients. No complications occurred such as infection or recurrent instability, nor were there any problems related to the skin and Kirschner wires.
  
  
  CONCLUSIONS
  Ligament reconstruction for the carpometacarpal joint of the thumb relieves pain and restores stability while preserving a functional range of motion in patients with chronic instability.
