Forty cases of intertrochanteric fractures of femur were treated with percutaneous nonmetallic external fixator. The patients were followed up for 6 months to 3 years, and the fractures were all united without coxa vara or shirtening deformities. There was no mortality in this series. This method had the advantages ofbeing simple, save time and effort, less traumatic and early ambulation. The design of the apparatus tallied with the biomechanics of the neck and shaft of the femur.

OBJECTIVE: Both primary and metastatic tumor of spine can influence spinal stability, spinal cord and nerves. The principles of dealing spinal tumor are resection of tumor decompression on spinal cord and reconstruction of spinal stability. METHODS: Since Aug. 1993 to Oct. 1996, 15 cases with spinal tumor were treated, including 4 primary spinal tumor and 11 metastatic tumor. Tumor foci were mainly in thoracic and lumbar spine. Graded by Frankel classification of spinal injuries, there were 1 case of grade A, 1 of grade B, 3 of grade C, 5 of grade D and 5 of grade E. Tumors of upper lumbar spine and thoracic spine were resected through anterior approach. Posterior approach also was adopted once posterior column was affected. Tumors of lower lumbar spine were resected by two-staged operation: firstly, operation through posterior approach to reconstruct spinal stability: secondly, operation through anterior approach. After resection of tumor, the spines were fixed by Kaneda instrument, Steffee plate or Kirschner pins. To fuse the spine, bone grafting was used in benign tumor and bone cement used in malignant tumor. RESULTS: Except one patient died from arrest of bone marrow, the others were followed up for 3 to 20 months. Postoperatively, 11 patients could sit up on one foot with the help of body supporter, and 9 patients could walk in two weeks under careful monitoring. There was no exacerbation of symptom and failure of fixation. The function of spinal cord was improved: 1 case from grade B to grade E, 1 from A to C, 2 from C to E and 4 from D to E. CONCLUSION: The spine can be reconstructed for weight bearing early by internal fixation. The symptom can be relieved and the nervous function can be improved by resection of tumor and decompression.
ObjectiveTo design an auto-compressive and anti-circumrotate intramedullary nail( ACACIN) and to evaluate the preliminary clinical efficacy on fixing adult femur fracture. Methods From January 1998 to June 2001, 23 patientswith femur fracture were stabilized with auto-compressive and anti-circumrotateintramedullary nail. 2-4 elastic blocks were installed into the proximal and distal different distance of quincunx nail to defend circumrotate and axis compress. Results Fracture healing were obtained in all 23 patients treated with auto-compresseiveand anti-circumrotate intramedullary nail, the time of fracture healing was 6-13 weeks in 21 cases and 15-22 weeks in 2 cases of old fracture. There was no complication related to infection, nail break, abnormal union and joint ankylosis. The results were excellent in 19 cases, good in 3 cases, and moderate in 1 case according Kolmert’s criterion for function ; the effective rate was 95.7%. Conclusion Auto-compressive and anti-circumrotate intramedullary nail has a suitable radian for adult femur, can afford stable fixation, anti-circumrotate andaxis compress.
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 determine the efficacy and complication rate of intramedullary nailing versus compression plate in the treatment of adult humeral shaft fracture. Methods We searched the specialized trials register of The Cochrane Collaboration’s Bone, Joint and Muscle Trauma Group, The Cochrane Library (including CENTRAL), MEDLINE (1966 to 2006), EMbase (1980 to 2006), PubMed (1966 to 2006), NRR , CCT and CBMdisc (1979 to July 2006). We also handsearched some Chinese orthopedic journals. Data were extracted and evaluated by two reviewers independently. Randomize controlled trials comparing intramedullary nailing versus compression plate for humeral shaft fracture in adults were included and the quality of these trials was critically assessed. Data analyses were done using The Cochrane Collaboration’s RevMan 4.2.8. Results Three randomize controlled trials involving 215 patients were included. The meta-analysis showed that intramedullary nailing may increase the re-operation rate (OR=2.68, 95%CI 1.19 to 6.04, P=0.02), pain in the shoulder (OR=13.02, 95%CI 2.23 to 75.95, P=0.004), and the rate of decreased range of motion of the shoulder (OR=18.60, 95%CI 1.01 to 341.83, P=0.05). The rates of no union, infection and iatrogenic radial nerve injury were comparable between intramedullary nailing and compression plate. Meta-analysis was not conducted for the time of union, because the relevant data were not available for the included trials. Conclusions Further well-designed and large-scale randomize controlled trials are required to determine the effects of intramedullary nailing and compression plate on these outcomes, because the trials available for this systematic review are too few and too small.
Objective To probe into the effectiveness of vertical compression of locking plate combined with hollow screws in the treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures. MethodsThe clinical data of 128 patients with Sanders type Ⅱ and Ⅲ calcaneal fractures who were admitted between March 2019 and April 2022 and met the selection criteria were retrospectively analyzed. Among them, 65 patients were treated with locking plate combined with hollow screw vertical compression (study group), and 63 patients were treated with simple locking plate (control group). There was no significant difference in baseline data between the two groups (P>0.05), such as gender, age, fracture side and Sanders classification, cause of injury, time from injury to operation. The operation time, intraoperative blood loss, hospital stay, and fracture healing time were recorded and compared between the two groups. Before operation and at 12 months after operation, the American Orthopaedic Foot and Ankle Association (AOFAS) score (including total score, pain score, functional score, and alignment score) was used to evaluate the recovery of foot function, and imaging indicators such as calcaneal width, calcaneal height, calcaneal length, Böhler angle, and Gissane angle were measured on X-ray films. ResultsAll patients were followed up 12 months after operation. There was no significant difference in operation time, intraoperative blood loss, hospital stay, and fracture healing time between the two groups (P>0.05). Poor wound healing occurred in 1 case in the study group and 2 cases in the control group. At 12 months after operation, there was no significant difference between the two groups in the pre- and post-operative difference of calcaneal length, calcaneal height, Gissane angle, and Böhler angle (P>0.05). However, the pre- and post-operative difference in calcaneal width in the study group was significantly higher than that in the control group (P<0.05). The pre- and post-operative difference of AOFAS total score in the study group was significantly higher than that in the control group (P<0.05), and further analysis showed that the pre- and post-operative difference of pain and function scores in the study group were significantly higher than those in the control group (P<0.05), while there was no significant difference in the pre- and post-operative difference of force score between the two groups (P>0.05). ConclusionCompared with simple locking plate treatment, the treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures with vertical compression of locking plate combined with hollow screws can more effectively improve the width of the subtalar calcaneal articular surface, avoid peroneal longus and brevis impingement, reduce pain, and increase the range of motion of the subtalar joint, and the effectiveness is better.
