ABSTRACT
OBJECTIVE@#To evaluate the clinical efficacy of short-term halo-pelvic traction (HPT) combined with surgery in the treatment of severe spinal deformities.@*METHODS@#In the study, 24 patients diagnosed as severe spinal deformity accepted the treatment of one-stage short-term HPT and two-stage surgery from January 2015 to May 2018 in our orthopedics department. 24 cases (9 males and 15 females) were retrospectively reviewed. The average age of the cohort was (28.8±10.0) years (12－48 years). The height, scoliosis angle, kyphosis angle, the height difference of shoulders, the height difference of crista iliaca, C7PL-CSVL and the perpendicular distance of S1 and the convex point of the patients were assessed at pre-traction, post-traction and post-surgery. The paired t test was used to analyze the difference among pre-traction, post-traction and post-surgery.@*RESULTS@#The average traction time of 24 cases was (2.5±1.1) weeks (1－5 weeks). The height of pre-traction and post-traction were (141.7±11.2) cm (116-167 cm) and (154.1±9.5) cm (136－176 cm) respectively, showing significant difference (P < 0.05), and the increased height was (12.4±4.6) cm (4－20 cm). The average scoliosis angle before traction was 104.9°±35.0°(25°－158°), and it was significantly decreased in post-traction[64.8°±21.0°(19°－92°)] and post-surgery[39.3°±17.0° (10°-70°)] (P < 0.05). The traction's coronal correction rate was 37.2%±10.9% (11.9%－51.2%) and the total coronal correction rate was 61.9%±12.6%(26.9%-79.0%). The average kyphosis angle before traction was 106.9°±29.2°(54°－163°), and it was significantly decreased in post-traction [63.1°±17.1°(32°－92°)] and post-surgery [39.0°±16.8°(10°－68°)](P < 0.05). The traction's sagittal correction rate was 40.0%±10.7%(16.7%－55.5%) and the total sagittal correction rate was 64.3%±10.7%(49.0%－87.5%). The average C7PL-CSVL before traction was (3.2±2.8) cm, and it was significantly decreased in post-traction [(2.5±2.5) cm] (P < 0.05). The perpendicular distance of S1 and the convex point before traction was (10.5±4.8) cm, and it was significantly decreased in post-traction[(8.4±3.5) cm] (P < 0.05).@*CONCLUSION@#The one-stage short-term HPT combined with two-stage surgery is a safe and effective procedure for severe spinal deformities. The clinical efficacy is satisfactory and the complication is relatively less.

Objective To evaluate renal function in congenital spinal deformities patients with urinary malformations.Methods We prospectively enrolled patients diagnosed with congenital spinal deformities combined with urinary malformation as well as age- and weight-matched healthy individuals and divided them into three groups:renal malformations group,urinary tract malformations group,and healthy control group.Serum creatinine,blood urea,blood uric acid,serum cystatin C,and estimate glomerular filtration rate(eGFR)level were used to evaluate general renal function.Urinary microalbumin(mALB),urinary alpha-1-microglobulin(α1-MG), beta-2-microglobulin(β2-MG),and N-acetyl-beta-D-glucosaminidase(NAG)level were determined to evaluate early renal function.Results We enrolled totally 16 patients with renal malformations,14 patients with urinary tract malformations group,and 20 healthy individuals as controls.The concentration of serum creatinine,blood urea, blood uric acid,serum cystatin C,and the value of eGFR in the three groups were within normal reference values, with no significant difference(P＞0.05).There were significant differences in the urinary levels of mALB,α1-MG and NAG in the three groups(P＜0.05),but not for the concentration of β2-MG(P＞0.05).Urinary levels of mALB and NAG were significantly higher in renal malformations group than in urinary tract malformations group (P＜0.05),but not for the concentration of α1-MG(P＞ 0.05).Conclusion Early renal function impairment occurs in congenital spinal deformities children with urinary malformation.Moreover,it appears more severe in patients with renal malformations than in those with urinary tract malformations.
ABSTRACT
Objective: To describe the occurrence of various spinal deformations in a captive-bred wild line of Poecilia wingei (P. wingei). Methods: Fish belonging to a wild line of P. wingei caught from Laguna de Los Patos, Venezuela, were bred in an aquarium home-breeding system during a period of three years (2006-2009). The spinal curvature was observed to study spinal deformities in P. wingei. Results:Out of a total of 600 fish, 22 showed different types of deformities (scoliosis, lordosis, kyphosis), with a higher incidence in females. Growth, swimming and breeding of deformed fish were generally normal. Conclusions:Possible causes for spinal curvature in fish are discussed on the basis of the current literature. While it is not possible to determine the exact cause(s) of spinal deformities observed in the present study, traumatic injuries, nutritional imbalances, genetic defects or a combination of these factors can be supposed to be involved in the pathogenesis of such lesions.
