Objective To investigate the curative effects of open reduction and internal fixation with Kirschner wire for Mason type-II radial head or neck fracture in children. Methods From September 2007 to June 2009, 17 cases of Mason type-II radial head or neck fracture were treated, including 11 males and 6 femals with an average age of 8.5 years (4-11 years).The locations were left side in 5 cases and right side in 12 cases. All fractures were caused by fall ing and classified as Mason type- II fracture. Two cases compl icated by radial nerve deep branch injury. The time from injury to operation was 4 hours to 5 days. All cases received open reduction and internal fixation with Kirschner wire. They were evaluated by anteroposterior and lateral radiographs and functionally by Broberg criteria. Results Wound healed primarily in all patients. According to Métaizeau criteria, the results were excellent in 15 patients and good in 2 patients, who achieved anatomical reduction. Seventeen patients were followed up for a mean time of 14 months (6-25 months). Function returned to normal in 2 cases compl icated by radial nerve deep branch injury after 6 months of operation. No compl ications of infection and nerve injury occurred. The X-ray films showed that bony heal ing was achieved in all cases; the heall ing time was 2.0-3.5 months (mean 3 months). According to Broberg criteria, the outcome was excellent in 11 cases, good in 4 cases, and fair in 2 cases, the excellent and good rate was 88.2%. Conclusion Open reduction and internal fixation with Kirschner wire has good effect, satisfactory functional recovery and less compl ication in the treatment of Mason type-II fracture of radial head or neck in children.
To evaluate the cl inical results of less invasive stabil ization system (LISS) for femur supercondylar and intercondylar fractures. Methods From March 2004 to November 2005, 47 patients with 49 intercondylar and supercondylar fractures were treated. Of all the patients, there were 34 males and 13 females with an average of 39.7 years (range 19-56 years). The locations were left side in 21 cases and right side in 28 cases. Fracture was caused by traffic accident in 31 cases, fall ing in 8 cases, violence in 6 cases and others in 2 cases. Forty-nine fractures included 14 intercondylar fractures, 21supercondylar fractures and 14 intercondylar and supercondylar fractures; 32 closed fractures and 17 open fractures. According to the AO typing, there were 6 type 33-A1, 8 type 33-A2 , 10 type 33-A3, 7 type 33-C1, 3 type 33-C2 and 15 type 33-C3. The disease course was 30 minutes to 6 days. Articular surface reduction was first performed, then the LISS plate was inserted via two incisions and locking screws were used later. Results The average operation time was 126 minutes (range 48-248 minutes). The blood loss was 180 mL(range 60-1 200 mL). The average follow-up time was 18.6 months (range 12-23 months). There were 4 patients with AP angular deformity and 5 patients with lateral angular deformity (range 2-5°). External rotation deformity was presented in 2 patients. There were no plate breakage, screw loosen and fixation failure. Average bone union time was 5.6 months (range 3-8 months) without infection case. Six cases were treated with il iac bone transplantation for delayed union. Conclusion LISS is one kind of effective treatment to femoral intercondylar and supercondylar fractures.
Objective To explore the injury mechanism, clinical features and treatment methods of multiple-level noncontiguous spinal fractures(MNSF). Methods The clinical data of 23 patients with MNSF were analyzed retrospectively. Therewere 15 males and 8 females aging from 13 to 75 years. Five cases missed diagnosis. The locations of the primary injury were cervical region in 3 cases, thoracic region in 7 cases, and thoracolumbar region in 13 cases. The spinal fractures associated with spinal cord injury were 14 cases in the primary injury, and 3 cases in the secondary injury. According to Frankel grade, there were 7 cases ofgrade A, 1 case of grade B, 3 cases of grade C, 6 cases of grade D and 6 cases of grade E. Sixteen cases were treated by surgical stabilization while 7 cases were treated conservatively. Results Twenty patients were followed up from 3 months to 4 years with a mean of 11.5 months except three patients. No neurologic deterioration was observed in patients who were treated conservatively or operatively. No wound infection, no implant failure or bone graft nonunion occurred in patients who were treated operatively. Among 17 patients with neurologic deficit before operation, 12 got 1-3 grade improvement of the Frankel grading, 4 remained unchanged and 1 died. Conclusion The mechanism of MNSF injury is complex, it is easy to miss diagnosis. The patients with spinal injury must be examined carefully and completely. A whole spine radiographic survey should be accomplished if necessary and treatments should be based on the stability of spine fractures and the severity of spinal cord injury.
ObjectiveTo explore the characteristics and treatment of intertrochanteric fracture, which the proximal part displaced forwardly and angularly.MethodsBetween March 2015 and March 2016, 40 patients with intertrochanteric fracture with forwardly and angularly displaced proximal part were treated with open reduction and intramedullary nailing fixation. There were 11 males and 29 females with the age of 56-87 years (mean, 75.7 years). The causes of injury included traffic accident in 1 case and fall in 39 cases. The body mass index was 18.9-33.8 kg/m2 (mean, 24.3 kg/m2). The time from injury to admission was 2-360 hours. The type of fracture according to AO-OTA classification was A1.2 type in 7 cases, A1.3 type in 1 case, A2.1 type in 6 cases, A2.2 type in 9 cases, A2.3 type in 12 cases, A3.2 type in 2 cases, and A3.3 type in 3 cases. The haemoglobin (Hb) value at admission and the lowest values before and after operation were recorded; the amount of transfused-blood during hospital stay and visible blood loss around operation were recorded. The short-form 36 health survey scale (SF-36) before injury and at 12 weeks after operation were recorded for evaluating the quality of living; the visual analogue scale (VAS) score at admission and at 2 days after operation were recorded for evaluating the degree of pain, the fracture union was evaluated by X-ray film and clinical examination, and the Harris hip scale were used to evaluate the injuried hip function at 12 weeks.ResultsThe lowest Hb value before operation was (99.10±16.48) g/L, which was significantly lower than that at admission［(114.33±14.93) g/L］(t=9.134, P=0.000). Eleven patients were treated with blood transfusion at amount of (520.00±269.98) mL before operation. The amount of transfused-blood during operation was (569.23±207.94) mL, and intraoperative blood loss was (373.08±154.68) mL. The lowest Hb value was (105.41±13.36) g/L after operation, and 8 patients were treated with second blood transfusion at amount of (500.00±185.16) mL. The reduction of fracture was rated as excellent in 16 cases, good in 18 cases, and poor in 6 cases according to the modified Baumgaertner criteria at 3 days after operation. Forty cases were followed up 12-15 weeks (mean, 12.8 weeks). No infection occurred. The VAS score at 2 days after operation was 3.2±0.5, which was significantly improved when compared with the value at admission (8.2±0.5) (t=37.500, P=0.000). At 12 weeks after operation, all the fractures healed; the Harris score was 82.5±6.9; and the SF-36 score was 51.4±11.5, which was significantly decreased when compared with the score before injury (54.9±11.5) (t=18.901, P=0.000). There were delirium in 4 cases, pneumonia in 8 cases, urinary infection in 5 cases, and venous thrombosis in 4 cases after operation. And all patients cured after corresponding treatment.ConclusionIntertrochanteric fracture with forwardly and angularly displaced proximal part is a type of unstable fracture, and it is difficult to reduction. It is necessary to achieve a good fracture reduction by means of auxiliary instrument. The anatomical alignment is the primary condition for the good effectiveness, and the anemia before and after the operation must be corrected.
Objective To describe the up-to-date development in spine and spine cord injuries. Methods To summarize the cl inical and basic research on spine and spine cord injuries were summarized by reviewing papers and combining them with our own experience. Results The occi pitocervical and atlantoaxial fusions by the pedicle or the lateral mass screw were widely used to treat the upper cervical fractures. The anterior cervical plate, posterior pedicle or lateral mass screw fixation techniques were used in treatment of lower cervical fractures. The cl inical appl ication of artificial cervical disc replacement showed the good biomechanical results in treatment of serious cervical disc diseases. However, there were no unified criteria for selection of the surgical approach, fixation level, and fusion model in the treatment of thoracolumbar spine fractures. Lumbar posterior dynamic fixation and artificial disc replacement for treatment of degenerative lumbar disc diseases provided the biomechanical stabil ization and reduced the morbidity of adjacent segment diseases, but there was lack of long-term follow-up results. The basic research in spine cord injuries, especially in apoptotic signal pathway, made great progress. The biological treatment including cell transplantation and gene therapy provided the sol id theoretical foundation for cl inical appl ication. Conclusion The reparative and reconstructive development in spine and spine cord injuries has made great progress in recent years.
Objective To explore the method and effectiveness of lateral calcaneal U-shaped incision approach to treat calcaneal fractures involving the talocalcaneal and calcaneocuboid joints. Methods Between January 2009 and March 2011, 36 cases of calcaneal fractures involving the talocalcaneal and calcaneocuboid joints were treated by the lateral calcaneal U-shaped incision approach and calcaneal anatomical plate fixation. There were 27 males and 9 females with an average age of 38.7 years (range, 19-58 years). According to the Sanders classification criteria, there were 12 cases of type II, 20 cases of type III, and 4 cases of type IV. The Bouml;hler and Gissane angles were (6.21 ± 10.48)° and (89.85 ± 12.34)°, respectively. The average time from injury to surgery was 4.2 days (range, 2-14 days). Results Superficial skin flap necrosis and wound exudate occurred in 1 case respectively, which were cured after dressing change; primary healing was obtained in the other cases. All the cases were followed up 12-26 months (mean, 15.2 months). The X-ray films showed that all fractures healed with an average healing time of 10.6 weeks (range, 8-12 weeks). The reduction of articular surface was satisfactory, and the heel height returned to normal. No complication of breakage of internal fixation or traumatic arthritis occurred. The Bouml;hler and Gissane angles were (29.64 ± 5.33)° and (121.75 ± 6.65)°, respectively at 3 months after operation, showing significant differences when compared with the preoperative values (t=43.800, P=0.000; t=33.200, P=0.000). The average time of plate removal was 11.2 months (range, 9-20 months). According to Maryland foot score, the results were excellent in 17 cases, good in 15 cases, and fair in 4 cases; the excellent and good rate was 88.9%. Conclusion The lateral calcaneal U-shaped incision approach is an effective method to treat calcaneal fractures involving the talocalcaneal and calcaneocuboid joints, which can expose the fracture fully, restore the anatomy of the calcaneal bone, and do early exercise under the condition of rigid internal fixation.
ObjectiveTo investigate the application and effectiveness of self-made spring plate in surgical treatment of acetabular posterior wall fracturejavascript:void(0)s.MethodsBetween June 2013 and June 2017, 38 patients with acetabular posterior wall fractures were treated. There were 27 males and 11 females with an average age of 53 years (range, 28-68 years). The injury caused by traffic accident in 18 cases, falling from height in 15 cases, and tumble in 5 cases. There were 4 cases of simple posterior wall fracture, 18 cases of posterior wall fracture with posterior dislocation of hip joint, 10 cases of posterior wall fracture with posterior column fracture, and 6 cases of posterior wall fracture with transverse fracture. The time from injury to admission was 1-4 days (mean, 2.5 days). The time from injury to operation was 4-8 days (mean, 5 days). After fracture reduction via the Kocher-Langenbeck approach (35 cases) or the combined ilioinguinal approach (3 cases), the spring plate was used to press the posterior wall fracture, and then the reconstruction plate was pressed against the spring plate and fixed to the posterior column.ResultsAll the incisions healed by first intention. All patients were followed up 12-36 months (mean, 28 months). Five cases of post-traumatic sciatic nerve injury and 2 cases of sciatic nerve injury caused by traction during operation were fully recovered at 3 months after operation. The imaging examination showed that all the fractures healed. The fracture healing time was 10-16 weeks (mean, 12 weeks). There was no ruptures or failures of internal fixation during the follow-up period. There were 2 cases of femoral head necrosis, 1 case of traumatic arthritis, and 1 case of osteomyositis at last follow-up. The hip joint function was rated as excellent in 27 cases, good in 5 cases, fair in 2 cases, and poor in 4 cases according to the Harris scores at 12 months after operation.ConclusionFor the acetabular posterior wall fracture, it has the advantages of easy to use and reliable fixation that the posterior wall fracture is fixed with spring plate firstly, and the spring plate is pressed to fix the posterior column with the reconstruction plate finally.
Objective To review the biomechanics of internal fixators for proximal humeral fractures, and to compare the mechanical stabil ity of various internal fixators. Methods The l iterature concerning the biomechanics of internal fixators for proximal humeral fractures was extensively analyzed. Results The most important things for best shoulder functional results are optimal anatomical reduction and stable fixation. At present, there are a lot of methods to treat proximal humeral fractures. Locking-plate exhibites significant mechanical stabil ity and has many advantages over other internal fixators by biomechanical comparison. Conclusion Locking-plate has better fixation stabil ity than other internal fixators and is the first choice to treat proximal humeral fractures.
ObjectiveTo evaluate the effectiveness of Cross-Union surgery for the treatment of pseudarthrosis of the tibia (PT) with neurofibromatosis type 1 (NF1). MethodsThe clinical data of 8 children of PT with NF1 who met the selection criteria between January 2018 and December 2023 was retrospectively analyzed. There were 5 boys and 3 girls, and the operative age ranged from 1.8 to 13.3 years with a median age of 3.5 years. According to Paley classification, there were 2 cases of type 2a, 2 cases of type 3, 2 cases of type 4a, and 2 cases of type 4c. There were 5 cases of first operation and 3 cases of re-fracture after previous operation. Six cases had leg length discrepancy before operation, and 2 of them had shortening over 2.0 cm. Except for 1 case of ankle fusion, the other 7 cases had ankle valgus. Preoperative coronal/sagittal angulation was recorded. Postoperative pseudarthrosis healing and refracture were observed. Leg length discrepancy and tibiotalar angle were measured and recorded before operation and at last follow-up. Inan imaging evaluation criteria was used to evaluate the imaging effect. ResultsAll patients were followed up 12-37 months (mean, 23.5 months). One pseudarthrosis failed to heal at 12 months after operation and healed at 3 months after reoperation, while the other pseudarthrosis healed with a healing rate of 87.5% and a healing time of 4-8 months (mean, 5.3 months). No refracture occurred during the follow-up. At last follow-up, there were 2 new cases with leg length discrepancy, which were 0.7 cm and 1.3 cm, respectively. In 2 cases with the leg length discrepancy more than 2.0 cm before operation, the improvement was from 4.1 cm and 12.6 cm to 2.1 cm and 9.0 cm, respectively. There was no significant difference in leg length discrepancy between pre- and post-operation in 8 cases (P>0.05). At last follow-up, 6 patients still had ankle valgus, and there was no significant difference in the tibiotalar angle between pre- and post-operation (P>0.05); the tibial coronal/sagittal angulation significantly improved when compared with that before operation (P<0.05). According to Inan imaging evaluation criteria, 1 case was good, 6 cases were fair, and 1 case was poor. Conclusion Cross-Union surgery is an effective method for the treatment of PT with NF1 in children, can achieve good bone healing results with a low risk of re-fracture. The surgery may not have significant effects on leg length discrepancy and ankle valgus, and further treatment may be required.
OBJECTIVE: To compare the clinical results of repairing bone defect of limbs with tissue engineering technique and with autogeneic iliac bone graft. METHODS: From July 1999 to September 2001, 52 cases of bone fracture were randomly divided into two groups (group A and B). Open reduction and internal fixation were performed in all cases as routine operation technique. Autogeneic iliac bone was implanted in group A, while tissue engineered bone was implanted in group B. Routine postoperative treatment in orthopedic surgery was taken. The operation time, bleeding volume, wound healing and drainage volume were compared. The bone union was observed by the X-ray 1, 2, 3, and 5 months after operation. RESULTS: The sex, age and disease type had no obvious difference between groups A and B. all the wounds healed with first intention. The swelling degree of wound and drainage volume had no obvious difference. The operation time in group A was longer than that in group B (25 minutes on average) and bleeding volume in group A was larger than that in group B (150 ml on average). Bone union completed within 3 to 7 months in both groups. But there were 2 cases of delayed union in group A and 1 case in group B. CONCLUSION: Repair of bone defect with tissue engineered bone has as good clinical results as that with autogeneic iliac bone graft. In aspect of operation time and bleeding volume, tissue engineered bone graft is superior to autogeneic iliac bone.
