Background Minimally invasive surgery has become popular because of the lower incidence of wound complications. However, achieving an anatomic reduction that provides a satisfactory outcome is difficult using minimally invasive surgery. Our study aimed to evaluate the reduction and clinical outcomes of closed reduction and percutaneous fixation treatment using a closed reduction traction device for displaced intra-articular calcaneal fractures compared with traditional open reduction plate fixation using an extended lateral approach. Methods A total of 40 patients and 45 feet with calcaneus fractures from 2012 to 2016 were studied. The open reduction plate fixation group (24 feet) was compared to the closed reduction percutaneous fixation group (21 feet) with a traction device. The reduction assessments included length, width, height, Bohler’s angle, Gissane’s angle, and varus or valgus angle before and after surgery. The clinical outcomes included the American Orthopaedic Foot and Ankle Society hindfoot score and the visual analog score for pain, length of stay, and complication rate. Results The patients were followed up for an average of 16.53 ± 3.95 months. No significant differences in reduction were observed between the open and closed groups ( P > 0.05). The American Orthopaedic Foot and Ankle Society scores of the two groups were 80.29 ± 6.15 and 83.62 ± 6.95 (open versus closed) ( P = 0.0957). The visual analog scores of the open and closed groups were 1.50 ± 1.22 and 0.81 ± 0.87 ( P = 0.0364). The lengths of stay in the open and closed groups were 9.63 ± 2.72 days and 6.71 ± 1.85 days ( P = 0.0002). The complication rates of the open and closed groups were 20.8% (5/24) and 4.8% (1/21) ( P < 0.0001). Conclusions The closed reduction percutaneous fixation with traction device method may provide equivalent reduction results and superior outcomes for the length of stay, VAS score, and complication rate for displaced intra-articular calcaneal fractures.
BackgroundProximal humeral fracture is a common fracture. Different approaches have been utilized in the surgical intervention of three-part fractures. Our study is to evaluate the clinical outcomes and effectiveness of a modified anterolateral approach and intra-osseous portal in minimally invasive treatment for three-part proximal humeral fractures in comparison to the traditional deltopectoral approach.MethodsFrom March 2015 to September 2016, 13 patients with three-part proximal humeral fractures were treated with internal fixation through the modified anterolateral minimally invasive approach (MIPO). These cases were compared to 20 additional cases using the deltopectoral approach (DP). Clinical and radiographic evaluations were performed, including the constant score (CS) and range of motion in abduction, flexion/extension and external/internal rotation. Complications were recorded as well.ResultsAll patients were followed up for a mean time of 12.12 ± 4.01 months. At the latest follow-up, no significant differences (p < 0.05) were observed in terms of length of stay, range of motion for abduction, flexion or internal/external rotation of the shoulder, Constant score or visual analog scors (VAS) for pain. Elbow flexion (142.31 ± 8.32 vs. 123.00 ± 10.18), posterior shoulder extension (41.92 ± 5.22 vs. 35.50 ± 5.83) and postoperative VAS (4.38 ± 1.04 vs. 6.15 ± 0.99) were significantly better in the MIPO group than in the DP group (p < 0.05). No significant differences were detected in the radiographic evaluation, and complications including axillary nerve injury were not present.ConclusionThe use of the modified anterolateral approach and intra-osseous portal is safe and effective for minimally invasive reduction and plating treatment for three-part proximal humeral fractures.
BackgroundSacral fracture and sacral nerve injury remain problems in orthopedics, especially in a sacral fracture combined with an anterior sacral nerve injury. Treating a sacral nerve injury with open reduction neurolysis or more conservative treatment cannot meet the clinical needs. Open reduction sacral nerve neurolysis will increase the number of severe, life-threatening injuries, regardless of whether the anterior or posterior approach is used. In recent years, computer- and robot-assisted orthopedic surgery has emerged as part of many clinical treatments.MethodsFor an unstable pelvic fracture with an anterior sacral nerve injury, we established a comprehensive and integrated solution. To achieve closed reduction, minimally invasive fixation, and minimally invasive anterior sacral nerve neurolysis, the Starr Frame, navigation robot, and Da Vinci robot were jointly applied.ResultsThe Starr Frame is very helpful for closed reduction percutaneous fixation in complex pelvic fractures. In this study, a minimally invasive fixation technique for the navigation robot in the pelvic fracture was explored. Although the patient had delayed anterior sacral nerve compression pain after surgery, we developed an approach and surgical method using the Da Vinci robot to explore the sacral nerve by celiac decompression. The patient was relieved of nerve pressure and pain.ConclusionsThis treatment method could be an alternative treatment for pelvic fractures and sacral nerve injury. The application of this treatment is a safe and feasible option that can be employed to manage early and late nerve repair with sacral fractures when open surgery or conservative treatment is unsuitable.
