ABSTRACT
Objective:To compare postural reduction combined with percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fractures (OVCFs).Methods:From January 2019 to January 2020,68 patients with OVCFs who met the inclusion and exclusion criteria in the Second Hospital of Tangshan Hebei Province were included in the observation study. A prospective randomized controlled study was used. The matched groups were divided into PVP combined group (adjust the overextension of the operating table by 20°-30°, if the posture reduction fails, pry the puncture needle on both sides in reverse according to the compression degree of the end plate before operation, and inject bone cement) and PKP group (do not adjust the operating table before operation, insert a balloon and expand on both sides after operation, and inject bone cement), with 34 cases in each group. The Cobb angle of the injured vertebrae was measured by taking the anterior and lateral X-ray film of the patient's lumbar spine before operation. The degree of pain and low back function were evaluated by visual analogue scale (VAS) and Oswetry disability index (ODI). The operation time and fluoroscopy times were recorded during the operation. On the second day after operation, the anterior and lateral X-ray of lumbar spine were taken to measure the Cobb angle of injured vertebrae. All patients were underwent computed tomography (CT) check the bone cement for leakage, record the VAS score, and record the ODI 3 months after operation to evaluate the patient's function. Follow up at the end of 12 months after operation to count the treatment cost and re-fracture of the patient. The data analysis and measurement data were compared by independent sample t-test between the two groups, paired sample t-test was used for intra-group comparison before and after operation. χ 2 test was used for counting data comparison between two groups. Results:All patients were followed up for 12 months. The operation time ((42.7±5.9) min), fluoroscopy times ((20.0±3.6) times) and treatment cost ((19 153±601) yuan) in the PVP combined group were better than those in the PKP Group ((67.4±7.3) min, (30.1±5.9) times, (27 496±669) yuan), and the difference was statistically significant ( t values were 15.39, 8.46, 54.12; all P<0.001). Cobb angle: Postoperative Cobb angle of injured vertebrae in the two groups (PVP combined group (10.7±4.5)°) and (PKP group (13.4±3.8)°) decreased compared with preoperative (PVP combined group (17.0±5.1)°) and (PKP group (16.7±5.1)°) ( t values were 10.61, 5.61; all P=0.001), and PVP combined group recovered better than PKP group, with statistically significant difference ( t=2.70, P=0.009). VAS score: Postoperative (PVP combined group (3.9±1.5) points) and (PKP group (4.1±1.6) points) was lower than preoperative the scores of (PVP combined group (6.9±1.1) points) and (PKP group (7.1±0.9) points), and the difference was statistically significant ( t values were 8.63, 8.88; all P=0.001). There was no significant difference in VAS scores between the two groups ( t=0.48, P=0.630). ODI scores: The scores of (PVP combined group (0.315±0.068)) and (PKP group (0.319±0.077)) after operation were lower than preoperative (PVP combined group (0.574±0.066), (PKP group (0.553±0.075)), and the difference was statistically significant ( t values were 18.54, 14.16, all P=0.001). There was no significant difference in ODI between the two groups ( t=0.25, P=0.803). There was no statistical significance in the two groups of postoperative bone cement leakage (χ 2=0.22, P=0.642). In PVP combined group, 1 case was re-fractured due to trauma, and there was no re-fracture in PKP group. Conclusion:Postural reduction combined with percutaneous needle prying reduction of PVP and PKP can alleviate the pain, improve the postoperative function and restore kyphosis in patients with OVCFs. Postural reduction combined with needle prying reduction of PVP has more advantages in operation time, radiation injury to doctors and patients, treatment cost, and the effect of correcting deformity is more significant.
ABSTRACT
Objective:To explore clinical results in reconstruction of finger C-shape soft tissue defect with the wrist crease free flap carrying cutaneous nerve.Methods:From June, 2017 to April, 2019, 7 fingers(7 patients) with C-shape defect were treated with the wrist crease free flap carrying cutaneous nerve. The size of defect ranged from 1.0 cm × 2.5 cm-2.2 cm × 4.0 cm; the flap sizes were 1.3 cm × 2.7 cm-2.5 cm × 4.5 cm. Five fingers had unilateral defect of proper palmar digital artery. Two fingers that had bilateral defect of proper palmar digital artery with poor blood circulation were re-established with blood supply by Flow-through flaps. Four fingers had unilateral defect of proper palmar digital nerves, and 3 had bilateral defect of proper palmar digital artery. Five of the fingers were repaired by the superficial branch of the radial nerve and 2 repaired by palmar cutaneous branch of median nerve. Regular outpatient follow-up was conducted after surgery for 8 to 15 (mean 11) months.Results:All the fingers and flaps survived with primary healing. Numbness existed in the areas of functional dominance of the cutaneous nerve. At the end of follow-up, the flaps showed good texture without significant bloated appearance with the recovery of protective sensation. The sensation of fingertip recovered to S 4 in 5 fingers and S 3+ in 2 fingers. Finger pulps were plump. All of the fingers moved freely. Linear scars were observed at donor sites and the wrists moved freely. Numbness feeling in the areas of cutaneous nerve disappeared at 6 to 8 weeks after surgery. According to the Functional Evaluation Criteria of the Finger Replantation published by the Hand Surgery Society of the Chinese Medical Association, the results were excellent in 6 fingers and good in 1 finger. Conclusion:The wrist crease free flap carrying cutaneous nerve is constant and can be dissected transversely to reconstruct and fit the C-shape defect of finger. It can re-establish the blood supply as well as to repair the proper palmar digital nerve defect at the same time.

ABSTRACT
Objective To evaluate the outcomes of distal leg and foot-ankle reconstruction with rotated single pedicel reverse sural neurocutaneous island flaps. Methods From June 2011 to January 2016, seventeen distal leg and foot-ankle defects cases repaired with rotated single pedicel reverse sural neurocutaneous island flap were analyzed retrospectively. In this study, 13 cases were male, and 4 cases were female. Age ranged from 25 to 65 years old, with an average age of 42.0 ± 8.3 years. Seven cases were distal leg defects, 3 cases were ankle defects, 3 cases were heel defects, and 4 cases were acrotarsium defects; all cases had bone and tendon exposure. The defects ranged from 5.0 cm × 7.0 cm-6.0 cm × 12.0 cm. The flap size ranged from 5.0 cm × 7.0 cm-8.0 cm × 15.0 cm. Results All 17 cases survived completely, without thanatosis, blisters and vascular crisis. The follow-up period was 12-48 months, and the mean was (20.0 ± 11.1) months. The color and elasticity of the flaps was excellent, with satisfactory appearances. Function and appearance of donor sites was not affected. Conclusions The rotated single pedicel reverse sural neurocutaneous island flaps have no injury on main nerves and arteries. The flaps have wide rotation angle and less invalid fold in the pedicel. The simple operation has satisfactory effects and high survival rate. It is a relatively easy procedure that can be applied toward repairing of distal leg and foot-ankle soft tissue defect.
ABSTRACT
Objective To recognize the relationship between high cutantous artery branches and descending branch of lateral femoral circumflex artery artery,and to investigate the blood supply of anterolateral thigh flap in clinical.Methods Retrospective analysis 152 cases of anterolateral thigh flap from November,2003 to December,2016.It contains cutting with descending branchs in 99 cases,cutting with lateral branchs in 43 cases,the union of them in 8 cases and high cutantous artery branches in 2 cases.Results The flaps survival in 147 cases,cutting necrosis in 3 cases and partly necrosis in 2 cases.Descending and lateral branchs were both dominance neurovascular bundle of vastus lateralis muscle,independently or commonly dominate the skin of anterolateral thigh,occurrence rate was 33.5％.Conclusion The descending branch of lateral femoral circumflex artery include lateral branch,all of which are the neurovascular bundles,supply the anterolateral thigh muscle,and divid into some perforator branches crossing the musle to the anterolateral thigh skin subsequently,which constitute "the anatomical functional unit".High cutantous artery branche is the one of all of the branches,its origin lies hight and arise from lateral branch.
