Abstract:
Objective To explore the treatment of fracture of ulna coronoid process. Methods Sixty-five patients (66 cases) of fractures of ulna coronoid process were treated between January 1997 and April 2005. There were 54 males and 11 females with an average age of 32 years old (range, 8-76 years old). 29 fractures occurred on the left extremity, 35 on the right and 1 on the bilateral. The mechanism of injury was fall in 23 sides, traffic injury in 16, wringer injury in 14, fall from a height in 10 and other trauma in 3. 60 cases were fresh fractures, 6 old fractures and 7 open fractures. 38 patient suffered multiple fractures in ipsilateral elbow. According to Regan-Morrey classification, there were 22 type Ⅰ, 30 type Ⅱ and 8 type Ⅲ. In addition, there were 6 cases with a sagittal fracture line which we defined them as "type Ⅳ". In this series, immobilization of the elbow in flexion or extension with a long arm plaster splint or cast were applied in 37 sides, open reduction and internal fixation in 23 sides, resection of fragments in 5 sides and reconstruction of coronoid process in 1. Results 43 cases(44 sides) were followed up for an average 15 months (range, 7-32 months). All the fractures healed well, and the averaged union time was 12.2 weeks with a range of 6-16 weeks. The clinical results were evaluated according to Morrey's scale, 25 sides (56.8%) were rated as excellent, 9 (20.5%) as good, 6 (13.6%) as fair and 4(9.1%) as poor. No deep infection, loosening or breakage of the internal fixators and other severe complications occurred except for 2 cases with subluxation of elbow joint and 2 cases with myositis ossificans. Conclusion For type I and some cases with a stable typeⅡand Ⅳ which have no or mildly displaced fragment of the coronoid process, conservative treatment are applicable. Open reduction and internal fixation are suitable for all type Ⅲ and some cases with an unstable typeⅡ and Ⅳ which have a obviously displaced fragment of the coronoid process.
