title: Prognostic factors of a satisfactory functional result in patients with unilateral amputations of the upper limb above the wrist that use an upper limb prosthesis.
abstract: OBJECTIVE
  The purpose of this study is to determine the prognostic factors of a satisfactory functional outcome in patients using upper extremity prosthetics with a proximal third forearm stump, and above, level of amputation.
  
  
  METHODS
  All patients with longitudinal deficiencies and traumatic amputations of upper extremity with a level of amputation of proximal third forearm and above were included. A total of 49 patients with unilateral upper extremity amputations that had used the prosthetic for a minimum of 2 years were included in the protocol. The Disability arm shoulder hand (DASH) scale was used to determine a good result with a cut-off of less than 40%. The independent variables were the level of amputation, the etiology for its use, initial age of use and number of hours/day using the prosthesis.
  
  
  RESULTS
  It was found that patients with a congenital etiology and those that started using the prosthetic before 6 years of age had better functional results.
  
  
  CONCLUSIONS
  It was found that when adapting a patient with an upper extremity prosthetic, which has a high rejection rate of up to 49%, better functional outcomes are found in those who started using it before 6 years of age, and preferably because of a congenital etiology. It was also found that the number of hours/day strongly correlates with a favorable functional outcome.
