| Popis: | BACKGROUND The purpose of this study is to evaluate the clinical outcomes of the elderly with coronal shear fractures (CSFs) of the distal humerus who had undergone open reduction and internal fixation (ORIF). METHODS Between April 2002 and March 2019, eight elderly patients (76.3 ± 5.1 years)with CSFs of the distal humerus were investigated retrospectively. Postoperative complications, the range of motion (ROM) of the elbow joint, and functional elbow scoring (Mayo elbow performance score; MEPS) were assessed. RESULTS The mean follow-up duration was 23.6 ± 13.9 months. CSFs were treated by a buried implantable headless screw or Kirshner wires or bioresorbable screw with/without lateral locking plates. There were no superficial or deep infections, or elbow joint instability. Seven patients obtained fracture healing, but one patient showed non-union. Osteochondritis dissecans was present in one patient. Three patients showed step-off deformity (> 2 mm) of the articular surface. Two patients displayed a collapse of the fractured articular surface. A patient with severe comminution of both the capitellum and the trochlear showed the collapse of the whole articular surface with osteonecrosis of the capitellum and trochlea. Mean the range of motion of the elbow were flexion, 116.3±12.7° and extension, -28.8±14.1°. The mean MEPS was 78.8±10.2 points, representing patients who scored an excellent (n=1), good (n=3), and fair (n=4). CONCLUSION ORIF yielded satisfactory outcomes for theelderly with noncomminuted CSF of the distal humerus. However, the cases with comminuted articular fragment or complex posterior fractures were still challenging. |
