Comparing the Results of Open Reduction and Internal Fixation of Transverse or Oblique Fractures of Ulnar Shaft By Intramedullary Fixation With Round Pin and Plating Method in Patients Referring to Ahwaz Imam Khomeini and Razi Hospitals From 2001 To 2003

Introduction: Intramedullary pinning with round pin as a method for fixing ulnar shaft fractures results in 20% non union. In this study we compared intramedullary fixation method with round pin and post operative splinting method . Materials & Methods: 62 patients with ulna fractures referred to Imam khomeini and Razi hospitals of Ahwaz from 2001 to 2003 were divided randomly into two equal groups. First group were treated by intramedullary pinning and control group with plating. Radius fracture was fixed with plate if accompanied by ulna fracture. In the first group a long posterior splint was used after operation for 6 weeks. Motions of elbow and wrist started whithin 3 weeks. In the second group splinting was done for one week and motions of the elbow and wrist begun whithin a week. Patients were followed up at intervals of 2,6,12 and 24 weeks after surgery. Nnonunion, malunion and the rate of wrist and elbow motions were compared in two groups. Results: nonunion, malunion , wrist stiffness and elbow stiffness in treated and control groups was 6.45%, 3.22%, 6.45%, 0% and 3.22%,0%,3.22%, 0% respectively. 75.8% of patients were male. Etiology of the fx was 72.5% indirect force and 27.5% direct force. The rate of associated injury of Radius fx with ulnar fx was 59.6% . The mean age of patients was 26.9 years. Conclusion: There was no significant difference between the result of treatment in two groups. Intramedulary fixation with round pin and postoperative splinting is an cheap and easy method that can be used instead of plating.
