Objective To explore the feasibility and clinical efficacy of debridement, bone graft fusion and internal fixation with one-stage operation in the treatment of advanced wrist joint tuberculosis. Methods The clinical data from 14 patients with advanced tuberculosis of wrist joint treated with debridement, bone graft fusion and internal fixation were analyzed retrospectively in Shandong Provincial Chest Hospital Affiliated to Shandong University from April 2010 to May 2017. Among them, 11 cases were male and 3 cases were female, the average age was (41.0±18.5) years old ranged from 7 to 85 years old. The pericarpal focus was completely debrided in all patients, the bone defect was implanted into allogeneic bone, microtitanium plate was placed on the radius and metacarpal for internal fixation, and the distal ulna about 1 cm was removed at the same time. All patients underwent systematic and standardized chemotherapy with anti-tuberculosis drugs for 12 months. The healing of surgical incision, complications, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level were analyzed. The functional recovery of wrist joint were analyzed using the score table of Buck-Gramcko/Lohmannn (scoring criteria: 9-10 scores was excellent, 7-8 scores was good, 5-6 scores was general, low than 5 scores was poor) and upper limb dysfunction (DASH table: 0 score was normal and 100 scores was extremely limited). Results The average time of follow-up was (14.0±2.1)months ranged from 12 to 18 months in all patients. Surgical incision was healing with one-stage in all patients. The ESR was decreased from (28.0±23.5)mm/1h to (6.1±2.1)mm/1h with which the average recovery time of ESR was (3.5±1.3)months ranged from 2 to 6 months. The CRP was decreased from (27.0±35.1)mg/L to (3.4±1.3)mg/L with which the average recovery time of ESR was (2.4±1.2)months ranged from 2 to 5 months. The score was increased from average (4.6±0.8) ranged from 3 to 6 before operation to (8.5±0.9) ranged from 7 to 10 after operation with the score table of Buck-Gramcko/Lohmannn. The assessment was improved satisfactory from poor in all patients before operation to excellent in 7 patients and good in the other 7 patients after operation. The score with DASH table was improved from the average (68.0±1.9) ranged from 65 to 70 to the average (30.0±2.8) ranged from 26 to 35 in all patients. All patients had good internal fixation position, no swelling and pain, and no complications at the follow-up. Conclusion The better clinical efficacy can achieved with debridement, bone graft fusion and internal fixation with one-stage operation based on effective chemotherapy in the treatment of advanced wrist joint tuberculosis.
Hematogenous disseminated tuberculosis is a kind of severe tuberculosis. With hysteresis imaging performances, the symptoms are often untypical, it is difficult to diagnose early. MDS is malignant,without specific clinical manifestations and abnormal performance of the blood system. A case of disseminated tuberculosis complicated with severe hematogenous cell loss in our hospital in April 2017 was reported. The patient presented with “dizziness and fatigue for 3 months, fever for 2 month”was firstly treated with anti-tuberculosis treatment, and then the clinical symptoms, pulmonary lesions and the performance of the blood system improved. The pulmonary lesions were further improvingd, while the blood system abnormalities were aggravated again. Finally, the blood disease was diagnosed as MDS with repeated bone marrow examination. This report aimed to improve the diagnosis and share treatment experience of disseminated tuberculosis complicated with MDS.

Objective To investigate the effect and value of one stage debridement and internal fixation of bone combined with drainage on treating non-specific primary thoracolumbar infection.Methods The pre- and post-operation clinical data were collected from 46 patients with primary thoracolumbar non-specific infection admitted in the department of orthopedics of the Chest Hospital of Hebei Province from July 2012 to June 2016. Those patients included 4 cases with infection in thoracic, 5 cases in thoracolumbar, 33 cases in lumbar, and 4 cases in lumbosacral. All patients received anti-inflammatory treatment for 2 to 4 weeks before operation. One stage debridement and internal fixation of bone combined with drainage was conducted. The average drainage time after operation was (14.0±4.3) days, ranged from 3 to 28 days. Pain relief, infection control situation, time to getting the patient out of bed after surgery, recovery of neurological function, and bone graft fusion were observed, and the efficacy was evaluated.Results Among the 46 cases in this study, 15 cases were bacterial culture positive, with a positive rate of 32.6%. The visual analogue scale (VAS) score at the third week was (2.59±0.20); compared with preoperative (7.09±0.25), the difference was statistically significant (t=11.35, P<0.05). The erythrocyte sedimentation rate (ESR) at the third week after operation was (43.30±3.13) mm/1 h; compared with preoperative (65.98±4.56 mm/1 h), the difference was statistically significant (t=5.45, P<0.05). The C-reactive protein (CRP) at the third week after operation was (17.15±1.10) mg/L; compared with preoperative (34.54±2.43 mg/L), the difference was statistically significant (t=9.63, P<0.05). One case received a second surgery, and the second surgery rate was 2.2% (1/46). Postoperative, the mean time of patients wearing a brace out of bed was (12.6±4.7) days, ranged from 5 to 21 days. Among the 12 patients with preoperative spinal cord nerve dysfunction, American Spinal Injury Association (ASIA) grade recovered form Grade A to Grade B in 1 case, and form A to C in 1 case, from B to C in 1 case, from B to D in 1 case, from C to D in 3 cases, and from C to E in 5 cases. The fusion time of interbody bone graft ranged from 3 to 12 months in 46 cases, and the mean fusion time was (7.6±1.8) months. According to the fusion standards, 35 cases were excellent, 9 were better, and 2 were good, resulting in an excellent and better rate of 95.7% (44/46).Conclusion For patients with non-specific primary thoracolumbar infection who has surgical indication, one stage debridement and internal fixation of bone combined with drainage is safe and feasible. It has the advantages of rapid infection control, pain relief, neurological recovery, and early ambulation and is an effective method in treating non-specific primary thoracolumbar infection.
Objective To explore the long-term effect of retrograde resistance exercise on postoperative rehabilitation of middle-aged and elderly patients with spinal tuberculosis complicated with osteoporosis.Methods From May 2014 to September 2016, 108 cases of middle-aged and old patients with spinal tuberculosis complicated with osteoporosis were admitted to the Spinal Minimally Invasive Department of the Eighth Medical Center of PLA General Hospital (the 309th Hospital of PLA), among whom 40 cases were selected randomly (control group). From October 2016 to May 2018, 92 middle-aged and old patients with spinal tuberculosis complicated with osteoporosis were admitted to the same department, among whom 40 patients were selected randomly (observation group). In the control group, the patients received routine functional exercise after the debridement and bone graft fixation, and patients of the observation group received retrograde resistance exercise by wearing a brace in the condition that the plate was well fixed by CT examination on the 14th day after the surgery. Disability index (ODI), intervertebral bone graft block total integration, functional recoveryⅠlevel degree, bone mineral density (BMD) of the right femoral neck were compared between the two groups of patients after 1 month, 3 months and 6 months discharged from hospital.Results The ODI of the patients of observation group were (10.35±3.26), (8.86±2.94) and (6.78±2.84) respectively after 1 month, 3 months and 6 months discharge, which were significantly lower than those of the control group ((12.34±3.56), (10.95±3.12) and (8.94±2.76) respectively) (t=2.607, 3.083, 3.449, P=0.005, 0.001, 0.000). The numbers of patients with the intervertebral bone graft fusion of recorery Ⅱ level in observation group were 5 (12.5%), 30 (75.0%) and 40 (100.0%) after 1 month, 3 months and 6 months respectively, which were significantly higher than those in control group (0 (0.0%), 20 (50.0%) and 34 (85.0%) respectively) (χ 2=5.333, 5.333, 6.486, P=0.021, 0.021, 0.011). The numbers of patients with the function of recovery I level in observation group were 5 (12.5%), 15 (37.5%) and 35 (87.5%) respectively, which were also significantly better than those in control group (0 (0.0%), 6 (15.0%), and 26 (70.0%)) (t=5.333, 5.230, 5.591, P=0.021, 0.022, 0.018). The BMD of the right femoral neck in observation group were (0.45±0.02)g/cm 2, (0.47±0.02)g/cm 2 and (0.47±0.03)g/cm 2 respectively after 1 month, 3 months and 6 months, which were lower than those of control group ((0.46±0.01)g/cm 2, (0.46±0.03)g/cm 2, (0.46±0.02)g/cm 2)). There were significant differences of BMD of the right femoral neck after 3 months and 6 months between the two groups (t=1.701, 1.682, P=0.046, 0.048). Conclusion The intervention of retrograde resistance movement is conducive to postoperative functional recovery, complete fusion recovery of intervertebral bone grafts, and increase of bone density in the right femoral neck, and in order to promote the recovery of patients.
To evaluate the feasibility, clinical and radiological outcome of single-stage debridement, spinal fusion and internal fixation through a posterior approach in the surgical management of patients with pyogenic spondylodiscitis.Methods From January 2012 to December 2016, 31 inpatients (19 males and 12 females; aged 33-79 years; mean age, 60.7±11.2 years) suffering from pyogenic spondylodiscitis were included. All the patients received a single-step radical debridement of the infected intervertebral disc space, posterior screw-and-rod instrumentation and spinal fusion. Intravenous or oral antibiotics were continued for 12 weeks postoperatively and patients were followed up routinely after the operation. The lesion was located in lumbar spine in 23 patients and thoracic spine in 8 patients. There were 17 patients with neurological dysfunction before the operation, among which 15 cases of ASIA D, 1 case of ASIA C and 1 case of ASIA B. At 1, 3, 6 and 12 months after surgery, X-ray, three-dimensional CT scan and MRI were performed. The changes in pain scores (visual analogue score, VAS) and nerve function based on ASIA classification and the correction of Cobb’s angles were assessed for efficacy evaluation.Results The operation time ranged 112-300 min (mean (184.9±46.9) min). The intraoperative blood loss was 200-1400 ml (mean (537.1±286.6) ml). All patients were followed up for (42.3±15.4) months on average (ranged 12-71 months). One of the 31 patients demonstrated of recurrent infection (3.2% (1/31)). The postoperative VAS scores of pain at 3 months (3.06±1.59), 6 months (1.77±1.28), 12 months (1.03±1.22), and last follow-up (0.42±0.85) were significantly decreased when compared with preoperative score (6.74±1.13) (t values were 13.15, 19.73, 18.12, 24.73, all P values <0.05). Postoperative neurological function was improved after surgery, 16 cases were restored to ASIA E and 1 was restored to ASIA D. The preoperative Cobb’s angle was (26.4±16.8)°in thoracic spine and (31.0±3.2)° in the lumbar spine. One month after operation, these Cobb’s angles improved to (21.4±14.6)° and (21.3±5.2)°, representing mean corrections of 5.0° and 9.7° in the thoracic and lumbar spines, respectively. The differences were statistically significant (t values were 4.41, 13.09, all P values <0.05). At last follow-up, these Cobb’s angles were (22.5±15.0)° and (23.8±4.8)°, representing mean losses of 1.1°(t=3.81, P<0.05) and 2.5° (t=15.30, P<0.05) in the thoracic and lumbar spine, respectively.Conclusion Single-stage debridement, spinal fusion and internal fixation through a posterior approach is an effective and feasible surgical method for pyogenic spondylodiscitis.
Multiple sites of osteoarticular tuberculosis combined with multiple cutaneous tuberculosis is very rare and difficult to be early diagnosed. One patient with multiple tuberculosis of bone and joint with multiple skin tuberculosis was reported, who was diagnosed and treated via collaborations of multiple related departments. In order to enhance clinicians’ knowledge and raise up their awareness to atypical multiple osteoarticular tuberculosis and complicated with skin tuberculosis, this paper conducted deep analysis and discussion on clinical diagnosis and treatment process of this patient. Meanwhile, it is helpful to improve clinicians’ abilities of TB diagnosis and treatment, which will bring benefits to the patients on early diagnosis and early treatment.
From January 2006 to January 2015, 45 patients with thoracolumbar tuberculosis treated with one stage anterior debridement, titanium mesh-bone graft fusion and posterior internal fixation in the First People’s Hospital of Yidu in Hubei province were included in this analysis. Among them, 20 cases were males, and 25 were females. They aged from 23 to 72 years old, with an average age of (46.02±10.13) years. There were 20 cases with thoracic tuberculosis, 10 cases with thoracolumbar spinal tuberculosis, 8 case with lumbar vertebral tuberculosis, and 7 cases with lumbosacral tuberculosis. The operation time, intraoperative blood loss, visual analogue scale (VAS) score, Frankel grade, angle of kyphosis, and erythrocyte sedimentation rate (ESR) before and after surgery were evaluated, as well as complications and bone graft fusion status. The average operation time of the 45 patients was (230.27±15.86)min, and the intraoperative hemorrhage was (489.89±35.87)ml. The preoperative VAS score was (7.50±1.13), and it decreased to (0.89±1.67) 3months after operation. The difference was statistically significant (t=22.23, P<0.001). As to postoperative neurological improvement, of the 7 cases with Frankel grade B before surgery, 4 cases recovered to grade E and 3 cases recovered to grade D; of the 8 cases with grade C and 15 cases with grade D before operation, all recovered to grade E. Preoperative kyphosis angle was (33.93±7.01)°, while the kyphosis angle was reduced to (15.07±3.45)° 3months after the operation; the difference was statistically significant (t=16.20, P<0.001). ESR decreased from (69.75±14.62)mm/1h before surgery to (13.16±5.27)mm/1h 3months after surgery; the difference was statistically significant (t=23.81, P<0.001). The 45 patients were followed up for 24-70months. No serious complications occurred after operation, bone graft was fused in all patients, and no internal fixation loosening and fracture appeared. Hence, we concluded that the one stage anterior debridement, titanium mesh-bone graft combined with posterior internal fixation for patients thoracolumbar spinal tuberculosis can effectively correct spinal deformity, reconstruct spinal stability, and improve the cure rate of spinal tuberculosis.
Objective To investigate the clinical efficacy of one-stage anterior debridement combined with rib graft fusion and anterior internal fixation with nail for diseased vertebrae.Methods Thirty patients with spinal tuberculosis who were admitted in Xi’an Chest Hospital and performed one-stage anterior debridement combined with rib grafting and anterior internal fixation during Jan. 2013 to Dec. 2015. There were 11 males and 19 females with average age (44.2±12.4) years old ranged from 23 to 70.The lesion segments were involved from T5 to L1 (no more than 2 segments in all cases). Operative time, intraoperative bleeding volume, incision healing, postoperative complication, and toxic symptoms of tuberculosis were recorded in all cases. The visual analogue scales (VAS) were observed before operation and two weeks and two years after operation in all cases. The neurological function Frankel grade according to the American Spinal injury Association (ASIA) were observed after operation. There were grade A in 3 cases, grade B in 2 cases, grade C in 5 cases, grade D in 12 cases and grade E in 8 cases before operation. The Cobb angles were compared before operation, two weeks and two years after operation in all cases.Results The average operative time was (178.0±33.6) min ranged from 120 to 240 min and average intraoperative bleeding volume was (507.5±148.9) ml ranged from 300 to 800 ml. No relapse cases, no incision healing poor, no complication with sinus and screw loosening occurred during average follow-up (25.9±6.6) months ranged from 24 to 36 months. The toxic symptoms of tuberculosis and spinal pain disappeared in all patients. The average VAS in the group after operation (1.4±0.5) was significantly lower than that before operation (6.5±1.5) at the last follow-up (2 years after operation) with significant difference statistically (t=15.759,P=0.000). The Frankel grades were no cases with grade A, grade B and grade C in each one case, grade D in 2 cases and grade E in 26 cases at the last follow-up (2 years after operation). The Cobb angle was average (19.1±7.4)° before operation and (13.6±3.9)° at the last follow-up. The improvement of Cobb angle before and after operation was significant difference statistically (t=5.003,P=0.000). The lesions of spinal vertebrae were basically healed and bone nonunion and pseudoarthrosis were not found in the patients. There were no screws of internal fixation loosened and broken and no bone graft absorbed and disappeared.Conclusion It is feasible for the treatment of spinal tuberculosis using one stage anterior debridement with rib graft fusion and anterior internal fixation with nails for diseased vertebrae. The operation is safe and reliable, and the efficacy of short-term follow-up is satisfactory.
Objective To evaluate the clinical effect of treatment of cervical spine osteomyelitis via single-stage anterior debridement and bone graft fusion.Methods A retrospective information of 58 cases (male 36 cases, female 22 cases,) with cervical spine osteomyelitis treated by single-stage anterior debridement and bone graft fusion from June 2010 to June 2016 was collected. The mean age of these patients was 62.7±12.4 years (range 17-79 years). There were 10 cases of suppurative cervical spondylosis, 35 cases of tuberculous cervical spondylosis, 7 cases of Brucella cervical spondylosis and 6 cases of cervical spondylosis of unknown origin. The disease controlling statues was evaluated based on laboratory result of erythrocyte sedimentation rate and C-reactive protein. Eck fusion and grading criteria were taken to evaluate the fusion of vertebral body. The clinical effects were evaluated using the Visual Analogue Scale (VAS) and the Japanese Orthopedic Association score (Cervical) of cervical function. The data were analyzed by SPSS 23.0 statistical software. The measurement data were expressed by ($\bar{x}$±s). The data of preoperative and last follow-up were compared by paired t test. P<0.05 was statistically significant.Results All of 58 cases of patients’ symptom were significantly improved. The cervical VAS score: average (5.3±0.8)points before operation, average (2.3±0.8)points,(0.9±0.5)points,(0.6±0.5)points in one month、 six months after operation and the last time follow up, respectively.The postoperative VAS score was significantly lower than that before operation(Z=-6.75, P=0.00), The JOA score: average (11.0±0.9)points before operation, average (13.6±1.0)points,(15.6±1.0)points,(15.9±0.8)points in one month、 six months after operation and the last time follow up, respectively. The postoperative JOA score was significantly lower than that before operation (t=-51.10,P=0.00). All patients were not found internal fixation loosening and fracture in the follow-up period. 5 patients had hoarseness after operation, follow-up observation after a month of recovery. 2 patients with pyogenic infectious occurred wound infection two weeks after operation and recovery by re-debridement. Conclusion Cervical spine osteomyelitis treated by single-stage anterior debridement and bone graft fusion had a definite curative effect which can completely remove the lesionand remove the nerve compression.
Objective To understand the clinical characteristics of osteoarticular tuberculosis (TB) in pediatric patients and to provide reference for developing prevention and treatment strategy.Methods The clinical information and data of 177 children with osteoarticular tuberculosis admitted to the West China Hospital of Sichuan University from 2013 to 2017 were collected, including the number of cases admitted each year, sex and age distribution, lesion location of tuberculosis, source and area of the patients. Their clinical characteristics were analyzed.Results From 2013 to 2017, a total of 177 children with osteoarticular tuberculosis were admitted to the West China Hospital of Sichuan University and 143 cases out of them were from Sichuan Province. The average number of hospitalized patients each year was 35.4 cases; 111 patients were male while 66 patients were female, and the ratio of male to female was 1.68∶1; the age of the patients ranged from 1 year to 14 years with an average of 6.4±3.6 years, and the age-group distribution of the patients was as follows: the proportion of infant and before school age (1-6 years old) was 56.5% (100/177), school age (7-12 years old) was 37.3% (66/177) and aged 12 years old and above was 6.2% (11/177). The hip joint was the most commonly affected (59 cases), then followed by spine (54 cases), knee joint (42 cases) and ankle joint (10 cases). The number of the patients who were from Liangshan Yi Autonomous Prefecture, Ganzi Tibetan Autonomous Prefecture, Aba Tibetan Autonomous Prefecture and other areas in Sichuan Province accounted for 50.3% (72/143), 13.3% (19/143), 11.2% (16/143) and 25.2% (36/143), respectively.Conclusion The pediatric patients with osteoarticular tuberculosis admitted to the West China Hospital of Sichuan University are mainly from Liangshan Yi Autonomous Prefecture, Ganzi Tibetan Autonomous Prefecture and Aba Tibetan Autonomous Prefecture in Sichuan Province, so those areas are priority on early prevention and treatment of bone and joint TB. Furthermore, most of the pediatric patients with osteoarticular TB are young children, which is the key group population for TB prevention and screening.
Objective To evaluate the clinical efficacy of one-stage anterior debridement, bone grafting fusion and posterior cortical bone trajectory (CBT) screw fixation in combination with traditional pedicle screw internal fixation in lumbar single-segment instumentation for the treatment of monosegment lumbar spinal tuberculosis.Methods From January 2015 to January 2016, 42 patients with monosegment lumbar spinal tuberculosis in the First Affiliated Hospital of the Air Force Military Medical University of PLA were included in this analysis. All patients were divided into two groups based on the posterior internal fixation technique that was applied according to patient’s clinical situation and wish. Internal fixation was performed by CBT screws combined with traditional pedicle screws in 21 patients (A group) and by traditional pedicle screws in 21 patients (B group) after anterior debridement and bone grafting fusion. The Cobb angle, the Frankel grade, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and visual analogue score (VAS) value of all patients were analyzed before and after surgery and during the follow-up period.Results Forty-two patients were followed-up from 18 to 30 months, with an average follow-up time of (24.1±4.5)months. Three months after surgery, the ESR, CPR and VAS were (13.5±5.5)mm/1h, (4.7±2.0)mg/L and (1.9±0.8) in group A and (12.9±4.9)mm/1h, (5.2±3.2)mg/L and (2.2±1.0) in group B, respectively. The differences were not statistically significant (t=0.32, -0.68 and -1.02; P=0.747, 0.500 and 0.312). The average correction degree and correlation loss of Cobb angle were (11.6±6.3)° and (1.7±1.2)° in group A and (9.9±5.9)° and (1.4±1.1)° in group B at the last follow-up, with no significant statistical differences (t=0.96 and 0.94; P=0.343 and 0.355). As to postoperative neurological improvement, 1 case with Frankel grade B before operation recovered to grade D; of the 5 cases with grade C before operation, 4 cases recovered to grade D and 1 case recovered to grade E; of the 26 cases with grade D before surgery, all recovered to grade E.Conclusion For patients with monosegment lumbar spinal tuberculosis, CBT screw fixation technique can fix and fuse the diseased single-segment and retain normal movement of the adjacent spinal column. It is indicative to monosegment lumbar spinal tuberculosis.
