Twenty cases of myelopathy secondary to cervical spondylosis had been treated by anterior expansive decompression and interbody iliac bone graft. Follow-up for 8 to 42 months, the therapeutic results were satisfactory without any obvious complications. The techniques of fenestration and bone graft were introduced. The advantages of this operation were discussed.
Objective To review the progress of surgical treatment for the thoracolumbar spinal tuberculosis. Methods The related literature of surgical treatment for the thoracolumbar spinal tuberculosis was reviewed and analyzed from the aspects such as surgical approach, fixed segments, fusion ranges, bone graft, and bone graft material research progress. Results Most scholars prefer anterior or combined posterior approach for surgical treatment of thoracic and lumbar tuberculosis because it possessed advantage of precise effectiveness. In recent years, a simple posterior surgery achieved satisfactory effectiveness. The fixation segments are mainly composed of short segments or intervertebral fixation. The interbody fusion is better for the bone graft fusion range and manner, and the bone graft materials is most satisfied with autologous iliac Cage or titanium Cage filled with autologous cancellous bone. Conclusion The perfect strategy for treating the thoracolumbar spinal tuberculosis has not yet been developed, and the personalized therapy for different patients warrants further study.
ObjectiveTo explore the safety and preliminary effectiveness of transintervertebral release, bone impaction grafting, and posterior column compressed-closing in the treatment of osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis.MethodsThe clinical data of 21 elderly patients with osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis were retrospectively analyzed between March 2016 and November 2017. There were 1 male and 20 females, aged 55-75 years, with an average of 64.8 years. The disease duration was 8-24 months, with an average of 13.1 months. The bone density T value ranged from ?3.4 to ?2.1, with an average of ?2.3. Lesion segments: T11 in 2 cases, T12 in 6 cases, L1 in 8 cases, L2 in 1 case, T11, 12 in 1 case, T12, L1 in 2 cases, and T12, L2 in 1 case. Preoperative neurological function was classified according to the American Spinal Injury Association (ASIA): 5 cases of grade D and 16 cases of grade E. All patients underwent transintervertebral release, bone impaction grafting, and posterior column compressed-closing. The effectiveness was evaluated by visual analogue scale (VAS) score and Oswestry dysfunction index (ODI) score before operation, at 3 months after operation, and at last follow-up. The neurological function was assessed by ASIA at last follow-up. Local kyphosis Cobb angle (LKCA), thoracic kyphosis (TK), lumbar lordosis (LL), and sagittal vertebral axis (SVA) were measured on the X-ray films of the full-length lateral spine of the patient before operation, at 1 week after operation, and at last follow-up.ResultsNo complication such as fracture of internal fixator or nerve injury occurred. LKCA, TK, and SVA were significantly improved at 1 week after operation and at last follow-up (P<0.05). There was no significant difference between at 1 week after operation and at last follow-up (P>0.05). There was no significant difference in LL before and after operation (F=3.013, P=0.057). The VAS and ODI scores were significantly improved at 3 months after operation and at last follow-up, and further improved at last follow-up when compared with the scores at 3 months after operation, showing significant differences between time points (P<0.05). Five patients with ASIA grade D neurological function recovered to grade E at 6 months after operation.ConclusionTransintervertebral release, bone impaction grafting, and posterior column compressed-closing for treating osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis has definite effectiveness, strong orthopaedic ability, and minimal trauma, which can effectively restore the sagittal balance of the spine, alleviate pain, and improve the patients’ quality of life.
OBJECTIVE To explore a simple and effective method for the treatment of ischemic necrosis of femoral head. METHODS The anterior region of hip joint was exposed by anterior hip route, a 1.5 cm x 1.0 cm hole was made at the upper region of the femoral neck just below the head. The necrotic bone and sclerotic bone were completely cleaned by drill and curettage until the fresh cancellous bone was exposed. After irrigation, the bone cavity was filled tightly by iliac bone graft until the collapsed femoral head recovered its normal shape. Traction and continuous passive motion(CPM) were performed at the early stage after operation. RESULTS Twenty cases with 29 femoral head ischemic necrosis (Marcus III to IV stage) were treated by above methods. After 1 to 3 years follow-up, the results were all satisfactory. The pain disappeared, and the functions of the hip joint were all excellent with almost normal walking and squatting. CONCLUSION The necrotic bone and the sclerotic bone can be removed by this method, thus optimal conditions for the reconstruction of blood supply is obtained. Abundant cancellous bone graft in the residual bone cavity can support the round shape of the femoral head. CPM is very important in the repair of hyaline cartilage and prevention of joint stiffness. It is a simple and effective method in treating femoral head ischemic necrosis.
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.
ObjectiveTo explore the effectiveness of vacuum sealing drainage (VSD) combined with open bone graft for tibial traumatic osteomyelitis. MethodsBetween June 2007 and December 2012, 23 cases of tibial traumatic osteomyelitis were treated, including 15 males and 8 females with an average age of 32.5 years (range, 22-48 years). The time from injury to admission was 7-18 months (mean, 8.6 months). There was local bone scarring in 15 cases, the size ranged from 8 cm×4 cm to 15 cm×8 cm. The CT multi-planar reconstruction was carried out preoperatively. Eleven cases had segmental bone sclerosis with a length of 1.5 to 3.8 cm (mean, 2.6 cm); 12 cases had partial bone sclerosis with a range of 1/3 to 2/3 of the bone diameter. On the basis of complete debridement, infection was controlled by VSD; bone defect was repaired by VSD combined with open bone graft. After there was fresh granulation tissue, the wound was repaired by free skin graft or local skin flap transfer. ResultsNail infection occurred in 2 cases, which was cured after the use of antibiotics. The wound healed at the first stage after repairing. All cases were followed up 10-18 months (mean, 13.5 months). In 11 cases of segmental bone sclerosis, the infection control time was 7-14 days (mean, 8.8 days); the bone healing time was 32-40 weeks (mean, 34.4 weeks); and the frequency of VSD was 3-6 times (mean, 4.5 times). In 12 cases of partial bone sclerosis, the infection control time was 7-12 days (mean, 8.3 days); the bone healing time was 24-31 weeks (mean, 27.3 weeks); and the frequency of VSD was 3-5 times (mean, 3.6 times). Infection recurred in 1 case, and the patient gave up the therapy. No infection recurrence was observed in the other patients. ConclusionThe VSD combined with open bone graft is an effective method for the treatment of tibial traumatic osteomyelitis.
ObjectiveTo evaluate the effectiveness of comprehensive management for early stage avascular necrosis of the femoral head (ANFH) by arthroscopic minimally invasive surgery by comparing with closed core decompression. MethodsBetween January 2007 and March 2010, 28 patients (33 hips) with early stage ANFH were treated with the procedure of arthroscopic core decompression combined with autogenous cancellous bone graft and bone morphogenetic protein (BMP) in 18 cases (21 hips, trial group) or with simple closed core decompression in 10 cases (12 hips, control group). No significant difference was found in gender, age, disease duration, etiology, and staging between 2 groups (P gt; 0.05). ResultsIncision healed primarily in all patients, and no infection occurred. All patients were followed up 2.5 years on average (range, 1-3 years). Pain relief and improvement of hip function were obtained in all patients at 6 months after operation. At last follow-up, the Harris scores were 85.67 ± 4.78 in trial group and 81.33 ± 7.03 in control group, showing significant difference between 2 groups (t= —2.10, P=0.04). Collapse of the femoral head was observed in 1 hip (Ficat stage II) of trial group, and in 2 hips (Ficat stage I ) and 2 hips (Ficat stage II) of control group; hip arthroplasty was performed. Significant difference in total effective rate was found between trial group and control group (95.24% vs. 66.67%; χ2=4.85, P=0.03). ConclusionArthroscopic core decompression combined with autogenous cancellous bone graft and BMP is more effective than traditional closed core decompression for treatment of early stage ANFH in pain relief, improvement of hip function, slowing-down the process of femoral head necrosis, reduction of hip joint replacement by accurate location of the lesions, and thoroughly debridement of necrotic bone.
