Objective To evaluate the cl inical effectiveness and advantages of one-stage posterior debridement, bone graft, and internal fixation for thoracic tuberculosis. Methods The data were retrospectively analysed, from 21 cases of thoracic tuberculosis undergoing one-stage posterior debridement, bone graft, and internal fixation between June 2007 andNovember 2009. There were 16 males and 5 females with an average age of 42.2 years (range, 22-73 years). The average disease duration was 13.2 months (range, 7-21 months). The lesions were located at the level of T5, 6 (1 case), T6, 7 (1 case), T8, 9 (4 cases), T9, 10 (3 cases), T10, 11 (5 cases), T11, 12 (6 cases), and T9-11 (1 case). According to the Frankel grading criterion, the neurological function was rated as grade B in 2 cases, grade C in 6 cases, grade D in 10 cases, and grade E in 3 cases. The preoperative Cobb angle was (26.3 ± 9.2)°. The erythrocyte sedimentation rate (ESR) was (35.9 ± 11.2) mm/ 1 hour. Results Thoracic tuberculosis was confirmed in postoperative pathological examination in all 21 cases. All incisions healed primarily without fistules formation. The average follow-up time for 21 patients was 16.2 months (range, 1-3 years). Bony fusion was achieved within 7-12 months (mean, 9 months) without pseudoarthrosis. No loosening and breakage of internal fixation were found, and no local recurrence occurred. The ESR decreased to (25.1 ± 8.9) mm/1 hour at 1 week postoperatively, showing significant difference when compared with preoperative value (t=5.935, P lt; 0.01); it decreased to (14.1 ± 4.6) mm/1 hour at 3 months postoperatively. According to Frankel grade, the neurological function was significantly improved at 1 year after operation (χ2=13.689, P=0.003). The average Cobb angle was (17.1 ± 4.5)° at 1 years postoperatively, showing significant difference when compared with preoperative value (t=7.476, P lt; 0.01). Conclusion One-stage posterior debridement, bone graft, and internal fixation has a good cl inical effectiveness for thoracic tuberculosis with less injury and complete focal cleaning, as well as a goodeffectiveness of spinal canal decompression and kyphosis deformity correction.
Objective To investigate the effectiveness in the treatment of single segment thoracic vertebra tuberculosis by limited decompression combined with epidural absorbable haemostat covering and vertebral plate reconstruction based on one-stage posterior approach, debridement, bone fusion, and internal fixation. Methods Between September 2005 and March 2010, 90 cases of single segment thoracic vertebra tuberculosis were treated by using limited decompression combined with epidural absorbable haemostat covering and vertebral plate reconstruction based on one-stage posterior approach, debridement, bone fusion, and internal fixation in 44 patients (treatment group) and by one-stage posterior approach, bone fusion, and internal fixation in 46 patients (control group). There was no significant difference in gender, age, disease duration, affected segment, Cobb angle, Frankle grade, erythrocyte sedimentation rate (ESR), and Oswestry disability index (ODI) between 2 groups (P gt; 0.05). Results All incisions healed by first intension. All 90 cases were followed up 24-44 months (mean, 38 months). There was no significant difference in ESR between 2 groups at 1 week and 3 months after operation (P gt; 0.05). Postoperative iconography indicated that the bone fusion rate of the treatment group was 100% and no epidural cicatricial tissue or failure of internal fixation was observed, showing significant difference when compared with control group (3 cases having failure of internal fixation) (P=0.032). The Cobb angles were significantly corrected after operation when compared with preoperative angles in 2 groups (P lt; 0.05). At 2 years after operation and at last follow-up, the Cobb angle and correction loss in treatment group were significantly better than those in control group (P lt; 0.05). The ODI and Frankel grade were significantly improved at last follow-up when compared with preoperative ones in 2 groups (P lt; 0.05); the treatment group was significantly better than the control group in the ODI, improvement rate of ODI (P lt; 0.05), and in Frankel grade (Uc=4.368, P=0.000). Conclusion Compared with conventional operation method, it is an ideal operation method to use limited decompression combined with epidural absorbable haemostat covering and vertebral plate reconstruction based on one-stage posterior approach, debridement, bone fusion, and internal fixation for treatment of single segment thoracic vertebra tuberculosis, with minimal wound, less complications, and good function recovery.
OBJECTIVE: To discuss the clinical properties, operative results of thoracic spinal stenosis and factors correlating with prognosis. METHODS: From September 1992 to January 2001, 16 patients who suffered from thoracic spinal stenosis caused by degeneration, ossified ligamentum flavum, diffuse idiopathic hyperostosis and trauma, were decompressed by operation. The operative method was selected according to the compressed position of spinal cord. All patients were followed up 6 months to 9 years. The pain severity, ambulatory status and paraplegia index were compared between before operation and after operation. The correlation between prognosis and ages, the length of stenosis and the duration of disease was studied. RESULTS: The results of Wilcoxon Signed Ranks Test show significant difference in pain severity, ambulatory status and paraplegia index between before operation and after operation (P lt; 0.01). The results of partial correlation analyzing show that only the duration of disease was correlated with paraplegia index (P lt; 0.05). CONCLUSION: Thoracic spinal stenosis frequently develops in the lower-thoracic segments in middle and old aged men. Decompression by operation early can achieve a good clinical result. Duration of disease affects the prognosis.
ObjectiveTo explore the safety and efficacy of thoracoscopic guided thoracic paravertebral block (TPVB) in resection of lung, and to provide strategies for enhanced recovery after surgery of lung surgery. MethodsA total of 180 patients with thoracoscopic surgery of lung (including sublobar resection and lobectomy) hospitalized between May 2021 and June 2023 were included. There were 108 females and 72 males with an average age of (62.15±7.36) years. Patients were divided into 3 groups. Patients received subcutaneous injection of ropivacaine (concentration: 0.375%, dose: 2 mg/kg) on peripheral incision at chest closing were allocated into a group A. Patients received ultrasound-guided injection of ropivacaine (concentration: 0.375%, dose: 2 mg/kg) at the TPVB point after chest closing into a group B. Patients received thoracoscopic guided injection of ropivacaine (concentration: 0.375%, dose: 2 mg/kg) before chest closing at the TPVB point into a group C. The baseline data of each group were compared, and the effectiveness outcomes included perioperative adverse drug reactions, pain scores, postoperative analgesic drug use and postoperative hospital stay were compared among the 3 groups. ResultsThere were no statistical differences in the baseline data of three groups, including age, weight, gender, incidence of previous underlying diseases, operation time, number of surgical incisions, number of drainage tubes inserted, and dosage of sufentanil or propofol used during surgery (P>0.05). There were no adverse anesthesia events in the 3 groups during the operation, the frequency of self-controlled intravenous analgesia pump, the VAS score, the incidence of adverse reactions, and the rate of postoperative analgesic drug use in group C was less or lower than the other two groups (P<0.05). The hospital stay in the group C and group B were lower than that in the group A (P<0.05). ConclusionThoracoscopic guided TPVB can reduce postoperative pain without increasing postoperative side effects, which had accelerated the enhanced recovery after surgery of lung.
OBJECTIVE: To discuss the value of anterior operation in fracture-dislocation of connect of cervical vertebrae and thoracic vertebrae. METHODS: From 1997, 21 patients with fracture-dislocation of connect of cervical vertebra and thoracic vertebrae were operated on. The interval between injury and operation was within 24 hours in 4 cases, 2-7 days in 9 cases, 8-14 days in 3 cases and within 4 weeks in 5 cases. The locations were C6,7 in 7 cases, C7 in 9 cases and T1 in 5 cases. The nerves function of spinal of all the cases have different degrees of injury. Classification of Frankel were the following: 3 cases of grade A, 6 cases of grade B, 9 cases of grade C, and 3 cases of grade D. The operative procedure included the following: anterior operation of cervical vertebrae; incision of most fracture vertebral body to decompress; transplantation of ilium bone grafting fusion; and internal fixation of anterior cervical vertebrae with locking-steel. RESULTS: In 21 patients, 1 died of accompanying by pulmonary infection; 20 were followed up 8 months to 3 years with an average of 21 months. All transplanted ilium had fused. The nerve function of spinal cord had recovered in different degrees(2 cases of grade A, 1 case of grade C, 9 cases of grade D and 8 cases of grade E); the turn of vertebral column was normal. No internal fixation failed. CONCLUSION: Anterior operation is a better way to treat fracture-dislocation of connect of cervical vertebrae and thoracic vertebrae with easy operation, less complications, satisfactory reduction of fracture and good stability.
ObjectiveTo explore the effectiveness of intertransverse bone graft after debridement and fusion combined with posterior instrumentation in patients with single segmental thoracic tuberculosis. MethodsBetween March 2014 and May 2015, 17 cases of thoracic tuberculosis were treated by the surgery of intertransverse bone graft after debridement and fusion combined with posterior instrumentation. There were 10 males and 7 females with an average age of 48.5 years (range, 18-70 years), and with a mean disease duration of 4 months (range, 1-9 months). The affected segments included T4, 5 in 2 cases, T6, 7 in 5 cases, T7, 8 in 3 cases, T9, 10 in 2 cases, T10, 11 in 4 cases, and T11, 12 in 1 case. The operation time, intraoperative blood loss, and hospitalization time were recorded. Postoperative plain radiography was taken to assess the decompression and internal fixation, and the fusion effect was evaluated by X-ray or CT examination. The erythrocyte sedimentation rate (ESR), C reactive protein (CRP), visual analogue scale (VAS), Oswestry disability index (ODI), and Kyphosis angle were recorded and compared; the nerve function was evaluated by American Spinal Injury Association (ASIA). ResultsThe mean operation time, intraoperative blood loss, and hospitalization time were 184 minutes (range, 165-220 minutes), 231 mL (range, 150-800 mL), and 18 days (range, 12-26 days) respectively. No complication of hematoma or wound dehiscence was found. All patients were followed up 17.9 months on average (range, 9-22 months). No bone graft failure, internal fixation broken, pleural effusion, cerebrospinal fluid leakage, wound infection, fistula formation, and other complications occurred. Satisfactory intervertebral fusion was obtained in all patients at 3-8 months (mean, 5.3 months) after surgery. The ESR, CRP, VAS score, ODI score, and Kyphosis angle were significantly improved at immediate after operation and last follow-up when compared with preoperative ones (P < 0.05), and the ESR, CRP, VAS score and ODI score at last follow-up were significantly better than those at immediate after operation (P < 0.05). At last follow-up, the nerve function was recovered to ASIA grade E from grade C (1 case) and grade D (6 cases). ConclusionIntertransverse bone graft is a reliable, safe, and effective way of bone graft applied to the single segmental thoracic spinal tuberculosis.
Objective To explore the feasibil ity and efficacy of percutaneous kyphoplasty (PKP) for the treatment of severe osteoporotic vertebral compression fracture (OVCF), and to assess the cl inical result of the PKP technique. Methods From May 2006 to October 2007, 12 patients with severe OVCF affecting more than 2/3 of the original vertebral body height were treated by using domestic PKP and percutaneous vertebroplasty (PVP) tool systems. There were 3 malesand 9 females, with the age of 56-82 years and a mean disease course of 4.2 months (1-49 months). Eleven thoracic vertebra and 4 lumbar vertebra suffered from severe vertebral compression fractures, which included 3 extremely severe thoracic OVCF. Four thoracic vertebra and 3 lumbar vertebra had not severe OVCF. There were 4 cases of single vertebral compression fracture, 6 cases of double fractures, and 2 cases of triple fractures. Only single side PKP and PVP were performed via extrapedicular approach in thoracic vertebra, and via transpedicular approach in lumbar spine under fluoroscopic control. Eight patients with severe thoracic compression fractures and 4 with severe lumbar fractures were treated by PKP. Four patients with relatively mild thoracic compression fractures and 3 with lumbar fractures were treated by PVP. Results The operation was successfully, 3 patients with extremely severe thoracic compression fractures received no intervention. The maximum expansion pressure of balloon was (1 068 ± 298) kPa, and the volume was (3.1 ± 1.2) mL during operation. The average operative time of PKP was (44.9 ± 10.6) minutes per vertebra, while the average operative time of PVP was (36.5 ± 6.8) minutes per vertebra. The average volume of injected bone cement was (2.5 ± 0.6) mL per thoracic vertebra, and (3.6 ± 1.2) mL per lumbar vertebra. The mean hospitalization time were (3.7 ± 1.6) days. Twelve cases were followed up 5-18 months (mean 8.6 months). The visual analogue scale scoreswere (2.35 ± 0.61) points 2 days after operation and (2.89 ± 1.07) points at last follow-up, there were statistically significant differences when compared with before operation (8.27 ± 1.36) points (P lt; 0.01). Extravertebral leakage of the bone cement into the paravertebral tissue and/or disc occurred in 6 patients (9 vertebra) without significant symptom. Conclusion One side approach PKP is a safe and effective technique for treatment of severe OVCF with markedly rel ief of pain.
