The Regan-Morrey classification, treatment, associated injuries, course and outcomes were evaluated. Of the 103 fractures, 34 were type IA, 17 type IB, ten type IIA, 19 type IIB, ten type IIIA and 13 type IIIB. A total of 44 type-I fractures (86%) were treated conservatively, while 22 type-II (76%) and all type-III fractures were managed by operation. <\/jats:p><jats:p> At follow-up at a mean of 3.4 years (1 to 8.9) the range of movement differed significantly between the types of fracture (p = 0.002). Patients with associated injuries had a lower Mayo elbow performance score (p = 0.03), less extension (p = 0.03), more pain (p = 0.007) and less pronosupination (p = 0.004), than those without associated injuries. The presence of a fracture of the radial head had the greatest effect on outcome. An improvement in outcome relative to that of a previous series was noted, perhaps because of more aggressive management and early mobilisation. While not providing complete information about the true details of a fracture and its nature, the Regan-Morrey classification is useful as a broad index of severity and prognosis. <\/jats:p>","DOI":"10.1302\/0301-620x.91b5.21755","type":"journal-article","created":{"date-parts":[[2009,4,30]],"date-time":"2009-04-30T22:16:17Z","timestamp":1241129777000},"page":"632-635","source":"Crossref","is-referenced-by-count":53,"title":["Management and outcome of 103 acute fractures of the coronoid process of the ulna"],"prefix":"10.1302","volume":"91-B","author":[{"given":"J.
