ABSTRACT

Objective To analyze the methods and effects for treating unstable posterior pelvic ring fracture combined with sacral nerve injury and further identify the relationships among the diagnostic methods,surgical approaches and clinical outcomes.Methods A total of 38 patients with posterior pelvic ring fracture combined with sacral plexus injury treated from January 2000 to January 2010 were enrolled in the study.There were 20 males and 18 females at an average age of 35 years (range,10 to 59 years).The causes of fractures included traffic injury in 20 patients,fall injury in 12,weighty object impingement injury in five,and stabbing injury in one.Classification of posterior pelvic ring fractures included fracture and dislocation of sacroiliac joints in eight patients,fracture of ilium wing in two and sacrum fracture in 28.According to the Denis typing of sacrum fractures,there was one patient with type Ⅰ fracture,14 with type Ⅱ fracture and 13 with type Ⅲ fracture.All 38 patients presented the decrease or loss of skin sensation around the lower extremities,perineal region and crissum.Simultaneously,30 patients suffered motor dysfunction of the lower extremities,while 20 patients had bladder and anus sphincter dysfunction or sexual disorder.Thirteen patients were suspected of sacral plexus avulsion and four of them were confirmed by myelography or MRI examination.All patients had at least one associated injury.The average ISS was 21.9 points ( range,9 to 47 points).Therapeutic methods were fracture reduction and fixation in the absence of nerve decompression for eight patients and nerve decompression for 30 patients including 26 patients being also managed by fracture reduction and fixation.Operation time ranged from 6 days to 6 months.The clinical outcomes were evaluated according to the British Medical Research Council (BMRC) evaluation criteria of sensation and movement function.Results Thirty-four patients were followed up for average 4.9 years ( range,1 to 10 years),during which their pelvis obtained stable recovery.The neurological outcome was excellent in two patients,good in four and unchanged in two in the nondecompression group and was excellent in 16 patients,good in nine and unchanged in one in the decompression group,with the decompression group superior to the non-decompression group ( P < O.05 ).Conclusions For unstable posterior pelvic ring fracture combined with sacral nerve injury,nerve decompression and release combined with internal fixation can better improve the sacral nerve function and obtain good pelvic ring stability and is worth of clinical application.

ABSTRACT

ObjectiveTo investigate the feasibility of Legacy pedicle screw system plus minimally invasive technique in treatment of Tile type C pelvic fracture and evaluate its therapeutic effects.MethodsFrom January 2008 to March 2010, 12 patients with closed Tile type C pelvic fractures were treated with Legacy pedicle screw system plus minimally invasive technique.There were seven males and five females, at age range of 21-60 years (average 39.6 years).All patients had sacrum fractures of the posterior pelvic rings.The anterior pelvic ring fractures included unilateral ischiadic ramus fractures in four patients and bilateral ischiadic ramus fractures in eight.Three patients were combined with shock.The anterior pelvic rings were fixed with minimally invasive reconstruction plates and the posterior pelvic rings fixed with minimally invasive technique plus Legacy pedicle screw system.ResultsThe operation lasted for average 90 minutes (range, 80-110 minutes) , with average intraoperative blood loss of 105 ml (range, 80-150 ml).All patients were followed up for average 18 months (range, 6-32 months), which showed that all patients got satisfactory reductions and that the fractures were healed at one stage, with average period of 11.5 weeks (range, 9-13 weeks).There occurred no infections, failures of internal fixations or nerve injuries.According to improved Lindahl standard of pelvic injury function assessment, the result was excellent in 10 patients and good in two, with average score of 78.6 points.Conclusions Under master of the surgical indications, Legacy pedicle screw system plus minimally invasive technique takes advantages of minor trauma, less intraoperative fluoroscopy, short operation time, good curative resuhs and few complications in treatment of Tile type C pelvic fractures by fixation of the posterior pelvic rings and reconstruction of the anterior pelvic rings.

ABSTRACT

Oversea students with rare languages are characterized by severe language barrier,difficulty in study,difficulty in administration,weakness of basic medicine teaching,and lack of standardized clinical manipulation.Based on these characters,reform of clinical teaching was undertaken during the teaching process.Definite teaching principles were made,teaching methods were innovated,and teaching materials of various media were carefully chosen according to the teaching situation,and were renewed continuously.Good teaching effect was achieved,and all the oversea students with rare languages were satisfied with our teaching.

ABSTRACT

The effect of sucrose polyester (SPE) on cholesterol levels in sera of rats under hypercholesteremic diet and of artificial hypercholesterolemia was observed. The results showed that in experiment Ⅰ when SPE 3 gra/rat/day was administered orally in accompanying with hypercholesteremic diet for 20 days, the elevation of cholesterol levels in sera of rats were obviously less than that of the group without SPE (P
