RESUMO
Objective:To discuss the application effect of enhance recovery after surgery (ERAS) combined with system nursing in patients with thoracolumbar fracture accompanied by nerve injury.Methods:A retrospective case-control study was conducted to analyze the clinical data of 84 patients with bilateral thoracolumbar fractures accompanied by nerve injury admitted to Henan Provincial People's Hospital from August 2017 to January 2020. All patients were treated with posterior thoracolumbar spinal canal decompression, bone grafting and internal fixation. There were 55 males and 29 females, aged 36-49 years [(43.2±5.2)years]. The injury segments were located at T 10-T 11 in 6 patients, T 11-T 12 in 38, T 12-L 1 in 31, and L 1-L 2 in 9. According to the Frankel classification of neurological function, 19 patients were rated as grade A, 22 grade B, 38 grade C, and 5 grade D. A total of 42 patients were treated by ERAS combined with system nursing (ERAS group), and 42 patients by routine rehabilitation nursing (routine nursing group). The hospitalization time, incidence of perioperative complications, and patients' satisfaction with nursing work were recorded. The visual analogue scale (VAS) and Oswestry disability index (ODI) were evaluated at postoperative 1 week and 3 months. The Frankel classification of neurological function and the MOS item short from health survey (SF-36) score were measured at postoperative 3 months. Results:All patients were followed up for 3-4 months [(3.2±1.7)months]. The hospitalization time in ERAS group was (10.9±1.6)days, significantly shorter than (14.4±1.2)days in routine nursing group ( P<0.05). The incidence of perioperative complications in ERAS group was 10%(4/42), significantly shorter than 29%(12/42) in routine nursing group ( P<0.05). The satisfaction rates in ERAS group and routine nursing group were 93%(39/42) and 76%(32/42), respectively ( P<0.05). At 1 week and 3 months after operation, the VAS in ERAS group [(1.7±0.4)points, (1.2±0.3)points]was significantly lower than those in routine nursing group [(4.8±0.9)points, (3.1±0.7)points]( P<0.05). At 1 week and 3 months after operation, the ODI in ERAS group [(13.5±1.8)points, (10.3±1.4)points] was significantly lower than those in routine nursing group [(17.9±2.0)points, (15.6±2.1)points]( P<0.05). At 3 months after operation, according to the Frankel classification, there were 2 patients with grade A, 9 with grade B, 13 with grade C, 13 with grade D and 5 with grade E in ERAS group, and there were 8 patients with grade A, 8 with grade B, 12 with grade C, 10 with grade D, and 4 with grade E in routine nursing group. The recovery rate of grade A or above in ERAS group was 95%(40/42), significantly higher than 81%(34/42) in routine nursing group ( P<0.05)]. At 3 months after operation, the SF-36 score in ERAS group was better than that in routine nursing group ( P<0.05). Conclusion:For patients with thoracolumbar fracture accompanied by nerve injury, ERAS combined system nursing can shorten the hospitalization time, reduce perioperative complications, improve patients' satisfaction, reduce pain, promote the recovery of nerve function, and improve the quality of life.
RESUMO
Objective:To compare the effect of the new anterior cervical spine memory compression fixation device (GYZ memory alloy plate) and traditional titanium plate on the range of motion (ROM) and stress of the adjacent segment after anterior cervical discectomy and fusion.Methods:An adult male volunteer was recruited for a fee. After excluding cervical malformations, fractures, infections and other diseases, C 3-C 7 thin-layer CT scans were performed. Import the scanned data into the finite element modeling software to establish the finite element model of the physiological group and verify itseffectiveness. After C 5,6 discectomy, the intervertebral fusion device was inserted, and the anterior fixation was assisted by a conventional titanium plate or a new type of fixator. Thus, the finite element model of the traditional titanium plate group and the new fixer group was established. The three models were imported into the finite element analysis software ANSYS 16.0, and a vertical downward axial load of 73.6 N was loaded to simulate the head weight and the torque of 1.0 N·m to simulate the cervical spine flexion, extension, left lateral bending, right lateral bending, left rotation and right rotation.Compare the changes of intervertebral disc ROM and stress in adjacent segments of physiological group, traditional titanium plate group and new type fixator group. Results:The intervertebral disc ROM under six conditions was basically similar to the results of previous studies, and the model was effective. In the adjacent segment C 4,5, the three groups of activities in the flexion, extension, left lateral bending, right lateral bending, left rotation and right rotation conditions were: physiological group 3.9°, 4.2°, 3.7°, 3.7°, 2.2° and 2.2°, traditional titanium plate group 4.6°, 4.7°, 4.3°, 4.4°, 3.3° and 3.1°, and new fixture group 4.4°, 4.3°, 4.0°, 4.2°, 2.8° and 2.7°. The maximum stresses of the intervertebral discs under three different working conditions were: physiological group 1.81, 1.60, 3.99, 2.06, 3.63 and 3.41 MPa, traditional titanium plate group 1.86, 1.67, 4.21, 2.16, 3.82 and 3.63 MPa, and new fixture group 1.84, 1.64, 4.17, 2.14, 3.78 and 3.58 MPa. In the adjacent segment C 6,7, the activities of the three groups in six working conditions were: physiological group 3.1°, 3.2°, 2.5°, 2.5°, 1.2° and 1.3°, traditional titanium plate group 4.2°, 3.7°, 3.4°, 3.0°, 2.1° and 2.2°, and new fixture group 3.5°, 3.3°, 2.5°, 2.7°, 1.8° and 1.9°.The maximum stress of the intervertebral disc under three different working conditions was: physiological group 0.45, 0.66, 1.12, 0.85, 0.84 and 0.82 MPa, traditional titanium plate group 0.62, 0.93, 1.55, 1.24, 1.44 and 1.27 MPa, and new fixture group 0.61, 0.92, 1.54, 1.22, 1.07 and 1.24 MPa. The ROM and disc pressure of adjacent segments in the conventional titanium plate group were higher than those of the new fixator group. Conclusion:Compared with the traditional titanium plate, the new type of anterior cervical memory compression fixator has less effect on the ROM and stress of adjacent segments, which may slow down the process of adjacent segments degeneration to a certain extent.
