ABSTRACT
Objective:To evaluate the curative efficacy of a buttress plate combined with Kirschner wires for treatment of Regan-Morrey type Ⅱ coronoid fracture after elbow terrible triad injury.Methods:A retrospective study was conducted of the 20 patients who had been surgically treated for Regan-Morrey type Ⅱ coronoid fracture after elbow terrible triad injury from August 2014 to August 2018 at Department of Pelvic Trauma, Henan Luoyang Orthopedic-Traumatological Hospital. They were 12 men and 8 women, aged from 18 to 60 years (average, 39 years), with 6 left and 14 right sides affected. All the coronoid fractures were fixated with Kirschner wires plus a buttress plate through the anterior approach, the radial head and lateral collateral ligaments (LCL) were repaired through the posterolateral approach, and the medial collateral ligament (MCL) was repaired or fixated with a hinged external fixator if necessary. The curative efficacy was evaluated at the last follow-up by range of motion (ROM) of the elbow, Mayo elbow performance score (MEPS), American Shoulder and Elbow Surgeons Scale (ASES) and radiographs of the elbow. Complications were also recorded.Results:The mean follow-up time was 18 months (from 12 to 24 months) and the mean healing time 5 months. At the last follow-up, ROM in flexion and extension of the affected elbow joint averaged 132.5°, ROM in elbow pronation-supination 150°, MEPS 88, and ASES 87. No subluxation or dislocation occurred after elbow surgery. The fracture of coronoid process was slightly displaced in one case but eventually healed without affecting any elbow function; fat liquefaction occurred around the posterolateral incision in 2 cases but healed after debridement; traumatic arthritic changes occurred in 5 patients but no significant dysfunction of the elbow was observed.Conclusion:A buttress plate combined with Kirschner wires can lead to fine curative efficacy for Regan-Morrey type Ⅱ coronoid fracture after elbow terrible triad injury.
ABSTRACT
Objective:To compare the curative effects between anatomic locking plate and common reconstruction plate in the treatment of acetabular posterior wall fracture.Methods:The 50 patients with acetabular posterior wall fracture were retrospectively analyzed who had been admitted to Department of Pelvic Trauma Surgery, Luoyang Orthopaedic Hospital of Henan Province from February 2015 to February 2020. They were assigned into 2 groups according to different internal fixation methods. In the reconstruction plate group of 24 patients whose fractures were fixated by a common reconstruction plate from February 2015 to June 2017, there were 21 males and 3 females with an age of (38.9±10.9) years. In the anatomical plate group of 26 patients whose fractures were fixated by an anatomic locking plate between July 2017 and February 2020, there were 20 males and 6 females with an age of (38.0±10.0) years. The 2 groups were compared in terms of operation time, intraoperative blood loss, reduction quality, hip function and complications at the last follow-up.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating the 2 groups were comparable ( P>0.05). The 50 patients were followed up for 18 to 26 months (mean, 22 months). The operation time [(132.8±8.6) min] and intraoperative blood loss [(357.0±14.7) mL] in the anatomic plate group were significantly less than those [(177.2±5.9) min and (492.0±17.6) mL] in the reconstruction plate group( P<0.05). Postoperative CT examination showed that 96.2% (25/26) of the patients in the anatomical plate group and 91.7% (22/24) of the patients in the reconstruction plate group had a fracture step ≤3 mm, showing no significant difference ( P>0.05). At the last follow-up, the excellent and good rate by Harris hip score was 92.3% (24/26) in the anatomic plate group, significantly higher than that (66.7%, 16/24) in the reconstruction plate group ( P<0.05). The incidence of complications was 3.8% (1/26) in the anatomic plate group, significantly lower than that [29.2% (7/24)] in the reconstruction plate group ( P<0.05). Conclusion:Anatomical locking plate is better than common reconstruction plate in the treatment of acetabular posterior wall fracture.
ABSTRACT
Objective:To investigate the efficacy of a minimally invasive three-window incision and internal fixation with a novel anatomical locking plate in the treatment of calcaneal fractures.Methods:A retrospective analysis was performed of the 46 patients with calcaneal fracture (Sanders typeⅡ and Ⅲ) who had been admitted to Department of Orthopedics, Luoyang Orthopaedic Hospital of Henan Province from February 2015 to May 2017. They were 22 males and 24 females, aged from 19 to 59 years (average, 39.0 years) and with 16 left and 30 right sides affected. They were all treated with a minimally invasive three-window incision and internal fixation with a novel anatomic locking plate. Their B?hler and Gissane angles, and height, width and length of the calcaneus were compared between preoperation, immediate postoperation and the last follow-up. Their ankle-hindfoot functions were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring scale at the last follow-up; their complications were recorded.Results:All the 46 patients were followed up immediately after operation and for 14 to 18 months (mean, 16 months). All the fractures achieved bony union after an average of 3 months (from 2 to 4 months). At immediate postoperation and at the last follow-up, their calcaneal B?hler angles (34.20°±3.62° and 34.05°±3.65°) and Gissane angles (131.45°±6.04° and 131.25°±5.88°), and calcaneal heights [(41.05±2.76) mm and (40.90±2.86) mm], widths [(25.65±1.53) mm and (25.55±1.64) mm] and lengths [(76.82±1.70) mm and (76.73±1.78) mm] were significantly improved compared with the preoperative values [10.55°±7.51°, 95.32°±12.16°, (26.10±4.54) mm, (37.71±3.42) mm and (65.91±2.10) mm] ( P<0.05). There were no significant differences in the above indexes between immediate postoperation and the last follow-up ( P>0.05). According to AOFAS ankle-hindfoot scores at the last follow-up, the efficacy was evaluated as excellent in 28 cases, as good in 12 cases and as fair in 6 cases, yielding an excellent and good rate of 87.0%. No incision infection occurred after operation. Conclusion:In the treatment of calcaneal fractures of Sanders type Ⅱ and Ⅲ, the minimally invasive three-window incision and internal fixation with the novel calcaneal anatomical locking plate can achieve satisfactory reduction and rigid fixation, effectively reducing postoperative incision complications.
