Open reduction and internal fixation compared with excision for unstable displaced fractures of the radial head

PURPOSE: To determine if excision of the radial head for treatment of an unstable, displaced fracture is associated with a higher rate of early complications or late arthrosis as compared with open reduction and internal fixation (ORIF). METHODS: Unstable, displaced fractures of the radial head treated with either excision (15 patients) or ORIF (13 patients) were compared. Implants were removed routinely during the study period. Three patients had instability after radial head excision: 2 were treated in a cast and 1 had temporary pinning of the ulnohumeral joint. Two patients in the ORIF cohort had failure of fixation that subsequently was treated with radial head excision: 1 had early hardware loosening and 1 developed a nonunion. RESULTS: At the 1-year follow-up evaluation there were no significant differences in the flexion or rotation arc. An average of 17 years after injury there was no significant difference in the flexion arc or rotation arc. One result was rated as unsatisfactory in each cohort according to the Mayo Elbow Performing Index. The average Disabilities of the Arm, Shoulder, and Hand (DASH) score was 5 points in the ORIF cohort and 15 points in the excision cohort. Eight patients in the excision cohort had arthrosis (5 mild, 2 moderate, 1 severe) compared with 2 patients in the ORIF cohort (1 mild, 1 moderate). CONCLUSIONS: Open reduction and internal fixation of an unstable, displaced fracture of the radial head occasionally fails, but it seems to reduce the risk of subsequent elbow dislocation and to protect against long-term arthrosis. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.     

Long-term outcome of operatively treated fracture-dislocations of the olecranon

OBJECTIVES: To report the long-term results of operative treatment of anterior and posterior olecranon fracture-dislocations and compare them with the results recorded fewer than 2 years after surgery. DESIGN: Retrospective case series with long-term evaluation. SETTING: Level I trauma center. PATIENTS AND PARTICIPANTS: Ten patients with anterior olecranon fracture-dislocation and ten patients with posterior olecranon fracture-dislocation were evaluated after an average of 18 years (range, 11 to 28 years) after injury. Fifteen patients had an early follow-up available at an average 14 months (range, 6 to 24 months) after surgery. The average age at injury was 30 years (range, 14 to 53 years). INTERVENTION: Treatment included plate and screw fixation (11 patients), tension band wiring (8 patients), and radiocapitellar transfixation (1 patient). Six patients had additional elbow surgery before the final evaluation. MAIN OUTCOME MEASUREMENTS: Flexion arc, arthrosis, Mayo Elbow Performance Index (MEPI), Disability of Arm Shoulder and Hand questionnaire (DASH). RESULTS: The mean arc of elbow flexion was 105 degrees (range, 15 to 140 degrees) at 1 year and 122 degrees (range 10 to 145 degrees; P = 0.01) at final evaluation. Radiographic arthrosis was observed in 14 patients (70%): severe in 3, moderate in 2, and mild in 9 patients. Five patients (25%) had ulnar nerve dysfunction at the final evaluation. The MEPI was excellent in 13 patients, good in 4, fair in 2, and poor in 1. The mean DASH score was 9 points (range, 0 to 53 points). CONCLUSION: The initial results of operative treatment of fracture-dislocations of the olecranon are durable over time.
