OBJECTIVE@#To evaluate the efficacy of gelfoam granules application in prevention of cement leakage via anterior vertebral wall in Kümmell's patients treated with percutaneous kyphoplasty (PKP).@*METHODS@#From June 2017 to December 2019, 13 patients with Kümmell disease were treated with PKP, and gelatin sponge was inserted into the anterior wall of vertebral body to prevent bone cement leakage. There were 3 males and 10 females, with an average age of (73.84±8.44) years. The visual analogue scale (VAS) was used to record the degree of pain before treatment and 1 day and 3 months after treatment; Oswestry Disability Index (ODI) was used to evaluate the thoracolumbar function before treatment and 3 monthsafter treatment;X-ray was used to observe the bone cement leakage after operation.@*RESULTS@#The VAS scores were 7.31±0.83, 2.92±1.13 and 1.69±1.11 before treatment and 1 day and 3 months after treatment, respectively. The VAS scores on the 1st day and 3 months after treatment were lower than those before treatment (@*CONCLUSION@#The application of gelfoam granules in PKP can effectively prevent the leakage of bone cement via the anterior vertebral wall of Kümmell patients, and reduce the risk of thermal and mechanical injury of soft tissues such as the aorta in front of the vertebral body, and does not affect the postoperative pain relief and the recovery of thoracolumbar function.

OBJECTIVE@#To investigate specific technique and clinical effects of closed folding top consolidation maneuver combined with splint fixation maneuver for consolidation and cedar bark external fixation splint for the treatment of double fractures of distal ulna and radius in children.@*METHODS@#From January 2017 to December 2019, 17 children with double fractures of distal ulna and radius were treated with closed folded apex consolidation maneuver, including 13 males and 4 females, aged from 4 to 11 years old with an average of (7.29±2.34) years old. The fractures were fixed with cedar bark splint and followed up for 6 months, and alignment of fracture was evaluated according to the latest X-rays by follow up, and function of the affected limbs was evaluated by Anderson forearm function evaluation criteria.@*RESULTS@#Fifteen of 17 children were successfully reset immediately, and 2 children were successfully reset again. The average fixed time was (25.00±3.35) days. At 6 months of follow up, 12 patients got excellent results, 3 good, 2 fair, and 0 poor according to Anderson forearm function evaluation criteria. The position of all children were larger than 3/4, and 10 children were received anatomical reduction, alignment of 4 children was less than 10°, 3 children was less than 15°. No complications such as fracture displacement, nonunion, compartment syndrome, and forearm rotation dysfunction occurred.@*CONCLUSION@#Restoration of distal radius double fracture in children with the combination of the closed folding and top fixation maneuver and splint fixation maneuver has advantages of higher success rate, lower complications, which could reduce operating difficultyand pain of patients.

OBJECTIVE@#To observe the open angle (OA), cervical curvature angle (CA), preoperative spinal cord compression rate(PSCR), postoperative spinal cord shift (PSCS) in patients with chronic compressive cervical myelopathy undergoing C3-7 single open laminoplasty, and to explore the possible mechanism and influencing factors of postoperative average spinal cord drift, so as to provide objective basis for predicting PSCS.@*METHODS@#From May 2012 to July 2016, 32 patients with multi-segmental chronic compressive cervical myelopathy who underwent single-door laminoplasty in our department were analyzed retrospectively, including 14 cases of cervical spondylotic myelopathy, 8 cases of developmental cervical spinal stenosis with cervical myelopathy, and 10 cases of ossification of posterior longitudinal ligament. The OA of cervical spine was measured on CT, the CA was measured on X-ray, the PSCR and PSCS were measured on MRI. The patients were divided into two groups according to PSCS(group A>=2.5 mm, group B0.1), and the partial regression coefficients of OA and PSCR were 0.113 and 0.059 respectively.@*CONCLUSIONS@#PSCS is the result of OA, CA and PSCR, among which PSCR has the most important influence, OA is the second, CA is the least. PSCS can be predicted by 0.059×OA+0.113×PSCR-2.266 equation, which provides a theoretical basis for preoperative evaluation of spinal cord decompression after surgery.

OBJECTIVE@#To explore the influencing factors and possible mechanism of axial symptoms(AS) after C₃-C₇ single open-door laminoplasty in patients with chronic compression cervical myelopathy.@*METHODS@#The clinical data of 32 patients with multi-segment chronic compression cervical cord disease treated by C₃-C₇ single open-door laminectomy from May 2012 to July 2016 were retrospectively analyzed. Including cervical spondylotic myelopathy of 14 cases, developmental cervical stenosis complicated with cervical myelopathy of 8 cases, ossification of posterior longitudinal ligament(OPLL) of 10 cases. There were 17 males and 15 females, aged from 47 to 82 years old with an average of 57.46 year, the course of disease was 5 to 35 months with an average of 22.4 months. The opening angle(OA), cervical curvature angle(CA), preoperative spinal cord compression rate(PSCR) and postoperative spinal cord shift (PSCS) were recorded. After 2 weeks of surgery, determining whether occurred an AS condition according to the AS assessment criteria, the patients were divided into a axial symptom group and a non-axial symptom group, the general data and imaging parameters of the two groups were compared and the factors that may be postoperative AS were analyzed by binary Logistic regression analysis.@*RESULTS@#At 2 weeks after operation, 13 patients occurred AS. There was no significant difference in gender, age and course of disease between axial symptom group and a non-axial symptom group (>0.05). In axial symptom group, OA was(36.76±9.35)°, CA was(11.53±4.36)°, PSCR was(27.83±1.72)%, PSCS was (3.17±0.81) mm, while in non-axial symptom group, above items were (33.03±10.52)°, (7.71±4.73)°, (25.16±3.59)%, (2.43±0.95) mm, respectively, there was significant difference in CA, PSCR, PSCS between two groups(0.05). The results of the binary Logistic regression analysis of 3 parameters(OA, PSCR, PSCS) and AS showed OA and PSCR were eliminated in dependent variables, and the partial regression coefficient of PSCR was 0.311, and =0.031.@*CONCLUSIONS@#CA, PSCR, and PSCS are related influencing factors of AS, and PSCS is a high risk factor for AS. C₄,₅ nerve traction caused by posterior spinal movement, postoperative dural self-expansion causes greater traction of the spinal cord, excessive deformation of the cervical spinal cord causes autonomic nerve damage or necrosis that dominates blood vessels may be the pathogenesis of AS, but this is only a theoretical inference, and further improved experiment is necessary to verify it in the future.
