Of the 155 patients with elbow trauma,
134 (86%) had a total of 152 elbow fractures that induce one of the following patterns: Extrarticular fractures were presented in 26 (17%) patients,
partial articular fracture in 73 (51%) patients and complete articular were demonstrated in 53 patients (35%). Coronoid process of the ulna fractures ( 55 patients,36%) and radial head ( 54 patients,36%) were the most common fractures.
Fiftyone (38%) of the patients with elbow fractures were males,
whereas 83 (62%) were females.
Eighteen (13,4%) of the patients presented with two different types of elbow fractures (11 males and 7 females).
Of the patients with extrarticular fractures,
16 (11,9%) presented with apophyseal avulsion (13-A1 type),
5 (3,7%) presented with a simple fracture (13-A2 type),
1 (0,7%) had multifragmentary metaphyseal fracture (13-A3 type),
1(0,7%) presented with fractured ulna and intact radius (21-B1 type),
26 (19,4%) presented with fractured radius and intact ulna (21-B2 type) and 5 (3,7%) presented with fractures of both bones (21-B3 type).
Partial articular fractures presented in 73 (51%) patients with the following patterns: 3 (2,2%) patients presented with a sagittal fracture of the lateral condyle (13-B1 type),
5 (3,7%) of the patients presented with a sagittal fracture of the medial condyle (13-B2 type),
7 (5,2%) had a coronal fracture of the condyle (13-B3 type),
27 (20,1%) presented with fractured ulna and intact radius (21-B1 type),
26 (19,4%) presented with radius fractured and intact ulna (21-B2 type) and 5 (3,7%) presented with articular fracture of one bone and extrarticular fracture of the other bone (21-B3 type).
The 73 (51%) complete articular fractures presented with the following patterns: 6 (4,5%) patients presented with an articular simple and a metaphyseal simple fracture (13-C1 type),
8 (6%) of the patients presented with an articular simple and a multifragmentary metaphyseal fracture (13-C2 type),
16 (11,9%) presented with an articular multifragmentary fracture (13-C3 type),
8 (6%) patients presented with a simple articular fracture of both bones (21-C1 type),
10 (7,5%) patients presented with an articular simple fracture of one bone and an articular multifragmentary fracture of the other bone (21-C2 type) and 5 (3,7%) of the patients presented with articular multifragmentary fractures of both bones (21-C3 type).
The most common subgroups include simple partial articular fractures of ulnar coronoid process (21-B1 type) in 27 patients (18 % ) and simple articular radial head fractures (22-B2 type ) in 26 patients (17%).
The 21-B1 subgroup include 11 males (40,7%) and 16 females (59,3%) whereas the 22-B2 subgroup include 15 (57,7%) males and 11 females (42,3%).
