Objective To evaluate the cl inical significance of the combination of intensified anti-tuberculosis treatment, posterior transpedicular screw system internal fixation, intertransverse bone grafting, and anterior approach focus debridement for the treatment of thoracolumbar tuberculosis. Methods From January 2005 to December 2007, 20 patients with thoracolumbar tuberculosis (T10-L3) were treated. There were 13 males and 7 females aged 21-64 years old (average 44 years old). The course of disease was 3 months to 3 years (average 10 months). The focus involved single vertebrae bodies in 8 cases, two vertebrae bodies in 9 cases, and three vertebrae bodies in 3 cases. The preoperative Cobb angle was 9-35° (average 26.7°). The neurological function was evaluated according to the Frankel grading criterion, there were 2 cases of grade B, 5 of grade C, 7 of grade D, and 6 of grade E. Vertebral body defect index score: 9 cases of 1-2 points, 7 cases of 2-3 points, and 4 cases above 3 points. After receiving the systemic five-drug treatment of anti-tuberculosis for 2-3 weeks, the patients underwent the posterior transpedicular screw system internal fixation and intertransverse bone grafting, and then received tuberculosis focus debridement via anterior approach, nerve decompression, and bone grafting fusion. Results The time of operation averaged 210 minutes and the mean blood loss during operation was 650 mL. Postoperatively, 2 patients had mild belting sensation in their thorax and 2 patients had mild pneumothorax. Their symptoms rel ived 2-3 weeks later without specific treatment. All the patients were followed up for 12-23 months. X-ray films showed that all the patients achieved successful bony fusion 6-18 months after operation, and the Cobb angle was 7-21° (average 15.2°) 12 months after operation without aggravation. The Frankel gradingsystem was used to assess the postoperative neurological function, 1 patient in grade B before operation was improved to grade C after operation, 1 patient in grade B was improved to grade D, 1 patient in grade C was improved to grade D, 4 patients in grade B were improved to grade E, and 7 patients in grade D were improved to grade E. All of the incisions healed and erythrocyte sedimentation rate became normal 2 weeks to 3 months after operation. All the patients showed no obvious abnormity in l iver and kidney function. There was no recurrence of tuberculosis. Conclusion It seems that the systemic drug treatment of antituberculosis before and after operation, the thorough debridement of focus during operation, and the effective and rel iable wayto reconstruct for the spinal stabil ity are the key points for the treatment of spinal tuberculosis.
ObjectiveTo investigate the effectiveness of a modified surgical treatment of old Monteggia fracture.
MethodsBetween March 2006 and December 2013, 40 cases of old Monteggia fracture were treated with modified operation. Modified operation procedure included expanding excision of pedicled forearm fascia flap for reconstruction of the annular ligament and repair of elbow radial lateral collateral ligament complex and extending osteotomy of the ulna, callus replantation, and internal fixation with steel plate. There were 26 boys and 14 girls, aged 2-10 years with an average age of 4 years. Injury was caused by falling in 24 cases, by traffic accident in 8 cases, and by falling from height in 8 cases. The disease duration was 2-11 months (mean, 4 months). Four patients had combined radial nerve palsy.
ResultsIncision healed by first intention after operation, without early complication of radial nerve palsy, fascial compartment syndrome, or decreased hand extensor muscle strength. All the children were followed up 1-5 years (mean, 2.5 years). X-ray films showed fracture healing, and the healing time was 10-20 weeks (mean, 15 weeks). During follow-up, 3 cases had re-dislocation. Neither hand dysfunction caused by hand muscle adhesion nor radial head bottleneck shape change was found. On the basis of the functional evaluation criteria by Mackay, the results were excellent in 32 cases, good in 5 cases, and poor in 3 cases; the excellent and good rate was 92.5% at last follow-up.
ConclusionThe modified surgical treatment of old Monteggia fracture is an effective method, with good matching of humeroradial joint and without internal fixation of the humeroradial joint.
Objective To explore the feasibility of combining high level Le Fort Ⅰ osteotomy with bone grafting in the same operation for correction of secondary midface deformities in cleft patients. Methods From January 2002 to January 2005, 10 patients suffering from secondary midface deformities were treated. There were 4 males and 6 females, aged from 16 to 32 years. The unilateral cleft was involved in 8 patients and the bilateral cleft in2 patients. All patients received combining high level Le Fort Ⅰ osteotomy with bone grafting in the same operation. The horizontal corticotomy of high level Le Fort Ⅰosteotomy on anterior wall of maxillary bone is higher than that of traditionalLe Fort Ⅰ osteotomy, it is only 5 mm close to infraorbital foramen. Results All 10 patients were satisfied with their appearances after operation. Dental articulation was improved greatly in 9 patients. With an X-ray re-examination, maxillary was returned to normal position in all patients. After a follow up from 6months to 2 years, dental arch had good appearance. The X-ray films showed no obvious bone absorption. The density of grafting bone was approximation to the normal bone.Conclusion High level Le Fort Ⅰ osteotomy can make notonly maxillary advance, but also regions of lateral and floor of nose and partial infraorbital region advance. Combining with bone grafting in the same operation can decrease the frequency of operation, save the treatment expense and obtain an ideal effect. So it is an effective method for correction of the secondary midface deformities in cleft patients.
Objective To study the past, present and future of bone grafting. Methods Related l iterature on bone grafting in recent years was extensively reviewed. Results Bone grafting had a history over 300 years, a variety of bone grafting candidates including autografting, allografting, xenografting, synthetic and composite bone grafting had been util ized in cl inical orthopedics at present. But bone autografting and allografting represented the preferred alternatives for bone grafting.It would be important trend in bone grafting to fulfill the optimizing design of biomaterials and constructing composite bone substitutes with cells, factors and scaffolds. Conclusion The future bone grafting might be focused on how to achieve the goal of the rapid osseointegration as well as the physiological bone reconstruction.
Objective To evaluate the cl inical outcomes of primary anterior focus debridement, bone autograft, and internal fixation via transperitoneal approach in treating tuberculosis of the lumbosacral junction. Methods From February 2002 to April 2007, 16 patients with tuberculosis of the lumbosacral junction underwent anterior radical debridement, autologous il iac bone graft (two pieces of il iac bone, 5 cm × 3 cm in size), and internal fixation via transperitoneal approach, including 4 males and 12 females aged 27-63 years old (average 38 years old). The course of the disease ranged from 6 to 18 months (average 10 months). All patients experienced various degrees of pain in the lumbosacral area and toxic symptoms of thetuberculosis. Nine cases were compl icated with radicular pain in the lower extremities, and 3 cases had saddle area anaesthesia. Two cases were initially diagnosed as lumbar intervertebral disc protrusion and treated accordingly. The segments involved by the tuberculosis were L5-S1 level in all cases. The average erythrocyte sedimentation rate (ESR) was 61 mm/hour. Imaging examination confirmed the diagnosis of spinal tuberculosis. All cases received four antitubercular drugs and nutrition support for nerve before operation. Operation was performed when hepatorenal function was normal, and the toxic symptom of the tuberculosis was under control or ESR was decreased. Results Operation was performed safely in all cases without injuries of abdominal viscera, major blood vessel, cauda equina nerve and ureter. All wounds healed by first intention. No recurrence of tuberculosis and formation of sinuses occurred. All cases were followed up for 12-37 months (average 21 months). No such compl ications as tuberculous peritonitis and intestinal obstruction occurred. No postoperative erectile dysfunction and retrograde ejaculation occurred in the 4 male patients. ESR was recovered to normal 3-6 months after operation, and regular X-ray and CT exams showed no displacement of grafted bone. All patients achieved bony fusion 12 months after operation without the occurrence breakage and loosening of titanium plate and screw. The radical pain in the lower extremities and the saddlearea anaesthesia disappeared. Four patients had pain in the il iac donor site, 2 patients had mild pain in the lumbosacral area, and the pain was el iminated after symptomatic treatment. The therapeutic effect was graded as excellent in 14 cases and good in 2 cases according to the therapeutic effect evaluation criteria of Chen and co-workers. Conclusion The surgical treatment of tuberculosis of the lumbosacral junction with primary anterior focus debridement, bone autograft, and internal fixation via transperitoneal approach can achieve satisfying bony fusion and reconstruct spinal stabil ity.
Objective To compare the effects and indications of total hip replacement(THR) and transplantation of vascularized bone graft in treating late ischemic necrosis of the femoral head.Methods From March 1986 to March 1993, 81 patients with late ischemic necrosis underwent treatment. Of 81 patients, 59 patients who suffered in unilateral hip were divided into 2 groups: 26 underwent total hip replacement and 33 underwent transplantation of vascularized bone graft. There was no significant difference in the Harris-scores of the two groups before operations (Pgt;0.05). The Harris hip scores were compared between different ages(＜30 years, 31.50 years, and ＞51 years) in two groups. Results The follow-up ranged from 10 years and 3 months to 16 years and 5 months (15 years and two months on average). The changes of Harrisscores of the two groups after operations had significant difference in initial stage（Plt;0.05）,but had no significant difference in the long term（Pgt;0.05）. The change of Harris-scores of patients who underwent total hip replacement had no significant difference between different ages （Pgt;0.05），but that of patients who underwent transplantation of vascularized bone graft had significant difference between different ages（Plt;0.05）. Both groupshad satisfactory effects in treating late ischemic necrosis of the femoral head. Conclusion Both methods are effective in treating late ischemic necrosis of the femoral head. Total hip replacement can be more effective insenior patients. Transplantation of vascularized bone can be more effective in young patients.
ObjectiveTo investigate the clinical efficacy and the indications of posterolateral fusion and pedicle screw short-segment fixation via injured vertebra for treating old thoracolumbar fracture combined with kyphosis in elderly patients.
MethodsBetween January 2012 and December 2014, 24 patients with old thoracolumbar fracture and kyphosis received posterolateral fusion and pedicle screw short-segment fixation via injured vertebra. Of 24 cases, 8 were male and 16 were female with an average age of 66.3 years (range, 56-79 years). The mean disease course was 17.5 months (range, 5-36 months). There were 13 cases of osteoporosis, 9 cases of osteopenia, and 2 cases of normal bone. The visual analogue scale (VAS) was 6.53±0.95, and Oswestry disability index (ODI) was 52.63%±5.74% preoperatively. The thoracolumbar kyphosis located at T10 to L2, and the kyphotic Cobb angle was (28.79±5.04)° before operation.
ResultsThe operation was completed successfully without related complications. The operative time was 1.2-2.3 hours (mean, 1.6 hours), and intraoperative blood loss was 80-210 mL (mean, 158 mL). No nerve injury occurred. Poor healing of incision was observed in 1 patient with diabetes, and primary healing of incision was obtained in the other patients. Nineteen patients were followed up 6-30 months (mean, 14.4 months), and there were 2 deaths. Pain relief and function recovery were obtained in 19 patients after operation. The VAS score and ODI were significantly decreased to 2.4±0.7 and 32.14%±5.12% at last follow-up (t=8.542, P=0.000; t=9.826, P=0.000). The kyphotic Cobb angle was significantly decreased to (21.23±4.30)° at immediate after operation (P < 0.05) and to (23.68±4.35)° at last follow-up (P < 0.05), but no significant difference was found between at immediate and last follow-up (P > 0.05). No loosening or breakage of internal fixation was observed during follow-up.
ConclusionPosterolateral fusion and pedicle screw short-segment fixation via injured vertebra is a safe and effective treatment for elderly patients with old thoracolumbar fracture combined with kyphosis (Cobb angle less than 40°).
OBJECTIVE: To investigate the effect of vascular pedicled rib grafting in treatment of the pyogenic infection of the thoracolumbar intervertebral space. METHODS: From November 1993, 7 cases with pyogenic infection of the thoracolumbar intervertebral space were adopted in this study. Among them, there were 5 males and 2 females, aged from 29 to 58 years old. The position of pyogenic infection located at T10 to 11 in 3 cases, at T11 to 12 in 2 cases and at T12 to L1 in 2 cases. During operation, the pyogenic infection was cleared completely and the rib with vascular pedicle was grafted into the intervertebral space. RESULTS: Followed up for 10 to 60 months, the bone graft unioned in 3 months for 5 patients and unioned in 4 months for 2 patients. There was no recurrence and raised kyphosis. CONCLUSION: The technique of vascular pedicled rib graft is simple, it can shorten the bone union time and reconstruct the stability of spine.
OBJECTIVE: To present a surgical choice for nonunion and bone defect. METHODS: From November 1994 to October 1997, 17 cases of nonunion of fracture and massive bone defect were treated by autogenous iliac bone and fibular bone with vascular anastomosis. Of 17 cases, there were 10 cases of nonunion of bone fracture, 7 cases of bone defect following tumor resection (4 cases of benign and 3 cases of malignant). Autogenous fibular bone grafting with vascular anastomosis, ranging from 12 cm to 29 cm in length, were employed in 12 cases; autogenous iliac bone grafting, ranging from 7 cm x 3 cm to 9 cm x 5 cm in size, were utilized in the other 5 cases. All of 17 cases were followed up for 10 months to 5 years, 3 years and 7 months in average, and were evaluated from clinical manifestation. RESULTS: Bone union was achieved in 10 cases of nonunion of fracture after bone grafting, bony refilling of the bone defect was observed in 4 cases due to benign tumor and 1 case due to malignant tumor. The other 2 cases of malignant tumor died from lung metastasis of the tumor 10 months and 12 months after bone grafting, respectively. CONCLUSION: Bone grafting is an effective surgical option in treatment of nonunion of fracture and bone defect.
【Abstract】 Objective To study a new method of alveolar cleft bone graft repair. Methods From April 2005to August 2006, 26 cases (30 sides) of alveolar cleft were treated with trabecular substance of self-il ium combined with the decalcified dentinal matrix of human (DDM). There were 16 males and 10 females, aged 6-12 years. Unilateral alveolar cleft was involved in 22 cases, bilateral alveolar cleft in 4 cases. All cases were accompanied by nasal wing collapse, 5 by deciduous tooth retention, 3 by malposed teeth and 1 by tooth deformity. Anterior occlusal radiographs and panoramic oral radiographs were taken to observe union and bone absorption before and after operation. Results Twenty-three patients achieved heal ing by first intention, oronasal fistulas were closed successfully. Infection occurred in one bilateral alveolar cleft case and bone tissue exposure in 2 cases. Wound healed by rinse or dressing change and inunction with MEBO. The X-ray films after operation showed bone bridge formation in the alveolar cleft. The stabil ity and continuity of body of maxilla were resumed. Four cases (6-9years old) were observed 6.5 months, 22 cases (9-12 years old ) were observed 8.6 months. According to Bergland for evaluation,the X-ray films after 3 months of operation showed 16 cases (16 sides) in class I (53.3%), 7 cases (8 sides) in class II (26.7%),2 cases (4 sides) in class III (13.3%), and 1 case(2 sides) in class IV (6.7%). The overall survival ratio of alveolar bone grafting was 93.3%, and the cl inical success ratio was 80%. Conclusion The DDM is good in alveolar cleft bone graft repair. It is better than using self-il ium only cl inically.
