title: Plate removal after ulnar-shortening osteotomy.
abstract: OBJECTIVE
  Ulnar-shortening osteotomy using plate and screw fixation is a reliable method for treating various wrist disorders. In some patients the plate remains as a source of discomfort even after the osteotomy has healed and the preoperative complaints have resolved. There is not a large body of information to guide the surgeon in the timing of plate removal should it be needed to address persistent forearm complaints caused by prominent hardware. This study investigated the outcome of patients who had removal of the plate because of persistent symptoms after undergoing ulnar-shortening osteotomy once radiographic healing was apparent.
  
  
  METHODS
  A consecutive series of 40 ulnar shaft-shortening osteotomies was performed in which 14 patients requested removal of the plate because of persistent tenderness despite nonsurgical management. There were 12 Rayhack (11 titanium, 1 stainless steel) and 2 Synthes 3.5-mm dynamic compression titanium plates used. Before removal radiographic union was documented by 2 sets of films taken in multiple planes at least 4 weeks apart. The average time to plate removal was 6.6 months.
  
  
  RESULTS
  All patients had resolution of the ulnar forearm pain after hardware removal. There were no repeated surgeries and all patients returned to their prior levels of activity or employment. Patients were followed-up for an average of 17 months after plate removal. There was 1 refracture in an osteoporotic patient when she fell down a flight of stairs 7 months after plate removal.
  
  
  CONCLUSIONS
  When used for fixation after ulnar shaft-shortening for ulnar-sided wrist pain of various causes 3.5-mm compression plates seem to be removable at 6 to 9 months in symptomatic patients with a low risk for refracture when sequential sets of x-rays confirm healing of the osteotomy site according to this small series of patients.
