ABSTRACT
ObjectiveTo observe the effects of Internet plus continuous rehabilitation nursing on older patients after lumbar fusion. MethodsFrom January, 2018 to August, 2021, 157 older patients after transforaminal lumbar interbody fusion (TLIF) in Department of Orthopedics, Chongqing General Hospital were retrospectively studied. A total of 66 patients accepting routine continuous rehabilitation nursing care were as control group, and 91 patients accepting internet plus continuous rehabilitation nursing care were as intervention group. They were assessed with Visual Analog Scale for pain (VAS), Oswestry Disability Index (ODI), Huaxi Emotional-distress Index (HEI) and Adult Health Self-management Skill Rating Scale (AHSMSRS) before, and one and three months after intervention. The compliance and nursing satisfaction were investigated with self-made questionnaire three months after intervention, and the postoperative complications were recorded. ResultsA total of 148 patients finished follow-up of three months, including 61 patients for the control group and 87 patients for the intervention group. The VAS, ODI, HEI and AHSMSRS scores improved in both groups one and three months after intervention (F > 85.4, P < 0.001), and improved more in the intervention group than in the control group (|t| > 3.645, P < 0.001). Both the compliance and nursing satisfaction were better in the intervention group than in the control group (χ2 > 5.478, P < 0.05), and no postoperative complication was observed in both groups. ConclusionInternet plus continuous rehabilitation nursing can promote the recovery of function, pain and psychological emotion, ability of self-management, compliance, and nursing satisfaction.
ABSTRACT
Objective To evaluate the effects of unilateral and bilateral diffusion of cement on osteoporotic vertebral compression fractures treated with percutaneous kyphoplasty (PKP). Methods A retrospective case control study was conducted on the clinical data of 127 patients with single segment osteoporosis vertebral compression fracture (OVCF) treated by unilateral puncture PKP between July 2013 and July 2015. According to whether the diffusion of bone cement crossed the median, all cases with OVCF were divided into unilateral and bilateral diffusion groups. The unilateral diffusion group (72 cases) included 29 males and 43 females, with an average age of 69.5 ± 2.6 years (range, 63-76 years). In terms of the injured segment, there were 38 cases of L1, 20 L2, 11 L3, two L4, and one L5. In the unilateral diffusion group, the preoperative visual analog score (VAS) was (7.8 ±0.9) points, the preoperative anterior vertebral height compression ratio was (32.5 ±6. 3)％, and the preoperative Cobb's angle of the injured vertebra was (9.2±1.3)°. The bilateral diffusion group (55 cases) included 22 males and 33 females, with an average age of 71.2 ±2.9 years (range, 61-80 years). In terms of the injured segment, there were 32 cases of L1, 13 L2, six L3, three L4, and one L5. In the bilateral diffusion group, the preoperative VAS was (7.6 ±0. 9)points, the preoperative anterior vertebral height compression ratio was (34.5 ±5.8)％, and the preoperative Cobb's angle of the injured vertebra (9.8± 1.5)°. The VAS, anterior vertebral height compression ratio of the injured vertebra, Cobb's angle of the injured vertebra, and injured and non-injured vertebra refracture 1 month and 1 year after operation were recorded. Results The patients were followed up for 12-16 months (mean, 14.6 ± 0.6 months) in unilateral diffusion group and for 13- 16 months (mean, 15.2 ±0.2 months) in bilateral diffusion group. The VAS score of the unilateral diffusion group was (3.0 ±0.4) points at 1 month after the operation and (2.2±0. 4) points at 1 year after the operation, respectively. The VAS score of the bilateral diffusion group was (2.1 ±0.4) points at 1 month after the operation and (1.5 ± 0.4) points at 1 year after the operation, respectively. The VAS score decreased significantly 1 year after operation compared with that before operation (P ＜0.05), and significant difference was noted between two groups (P ＜0.05). The anterior vertebral height compression ratio of the unilateral diffusion group was (15.2±3.9)％ at 1 month after the operation and (16.3 ±3.4)％ at 1 year after the operation, respectively. The anterior vertebral height compression ratio of the bilateral diffusion group was (15.6±3.5)％ at 1 month after the operation and (16.8 ±3.9)％ at 1 year after the operation, respectively. The Cobb's angle of the injured vertebra of the unilateral diffusion group was (2.9±0.7)° at 1 month after the operation and (3.0±0.6)°at 1 year after the operation, respectively. The Cobb's angle of the injured vertebra of the bilateral diffusion group was (3.0 ± 0.7) ° at 1 month after the operation and (3.2 ± 0.7) ° at 1 year after the operation, respectively. The anterior vertebral height compression ratio and Cobb's angle of the injured vertebra decreased significantly after surgery (P ＜ 0.05), but no statistically significant differences were observed between two groups (P＞0.05). The injured vertebra refracture ratio was 6.9％ in unilateral diffusion group and 0 in bilateral diffusion group. The non-injured vertebra refracture ratio was 5.6％ in unilateral diffusion group and 5.5％ in bilateral diffusion group. No nerve root injury, cerebrospinal fluid leakage, pulmonary embolism, anaphylactic shock and postoperative infection were found in the two groups. Paravertebral bone cement leakage occurred in two cases of the unilateral diffusion group and anterior vertebral bone cement leakage occurred in one case of the bilateral diffusion group. Conclusion Compared with unilateral diffusion, bilateral diffusion of bone cement has better analgesic effect and can reduce the incidence of re fracture of injured vertebra, without increasing the risk of re-fracture of the non-injured vertebrae.

ABSTRACT
<p><b>OBJECTIVE</b>To compare the related clinical outcomes of total disc replacement (TDR) versus fusion in management of lumbar degenerative disc disease (LDDD)and provide available basis for choice of surgical procedure.</p><p><b>METHODS</b>Computer systematically researched PubMed,EMBase, COCHRANE Library, CBMWin, CNKI, VIP databases for randomized controlled trials comparing TDR and fusion for LDDD. Data were searched until October 2013. The available statistical data was extracted after methodological assessment. The statistical soft RevMan 5.1 was used to analyze the results.</p><p><b>RESULTS</b>Total 1 658 cases of patients in 6 studies were conducted, including 543 cases of fusion and 1 115 cases of TDR. The results of Meta-analysis showed that TDR was superior to fusion in term of visual analogue scale (VAS) (OR = -3.33, 95%CI:-5.94--0.71, P = 0.01) , Oswestry disability index (ODI) (OR = -5.21, 95%CI:-7.51--2.92, P = 0.00) , complication (OR = 0.45, 95%CI:0.21-0.95, P = 0.04) . There were no statistically difference regarding operating time, blood loss and reoperation (P > 0.05). However, there was no difference in term of complication in two-year and five-year sub-analysis.</p><p><b>CONCLUSION</b>Regardless TDR may be more effective comparable to lumbar fusion at the immediate postoperative time, vigorous evidence is still requisite to certify the result in long-term follow-up.</p>
