Objective To observe the branches and distribution of the tibial nerve and analyze the compressed position of it.Methods Twenty sides of adult cadavers were anatomized and the tibial nerve branches in ankle,foot,the internal and external plantar tunnel were observed.Correlated data was measured and recorded.Results ① The tendinous part of abductor hallucis muscle that was located under the muscle and consisted the surface of the internal and external plantar tunnel was(8.62?0.79)cm in length,(3.01?0.30)cm in width,and the thickness of it was about(0.24?0.02)cm.The internal and external nerves were located in the internal and external tunnel.The length of the internal tunnel was about(4.58?0.41)cm,and the diameter was(1.11?0.10)cm.The length of the external tunnel was about(2.58?0.23)cm,the diameter was about(0.96?0.08)cm.② Internal hell nerve was in an isolated tunnel interior the hell,which was the hell tunnel.The length of the hell tunnel was about(3.03?0.21)cm,the diameter was(1.07?0.09)cm.Conclusion The tibial nerve branches can be compressed at internal,external plantar tunnel or the heel tunnel.When making neurolysis of the tibial nerve for tarsal tunnel syndrome patients,except for the flexor retinaculum,the internal and external plantar tunnel and the hell tunnel should also be decompressed especially for the patients with the symptom of compressed single branch.

BACKGROUND:Traditional studies on foot and ankle biomechanics have limitation. Ankle joint was complicated and had big range of motion, so it is difficult to establish finite element models and to analyze the type of fracture.
OBJECTIVE: To construct the finite element models of distal tibial fractures and analyze the stability.
METHODS: CT data of ankle were colected from a normal male volunteer and the three-dimensional reconstruction of volunteer was made by Mimics software, and the effectiveness was verified. The ratio of different joint involvement and height of fracture block were assumed with Solidwork software, and finite element models of distal tibial fractures were established. Fracture stability was analyzed by ANSYS software using finite element method.
RESULTS AND CONCLUSION:The distal tibia fracture model was consistent with the relevant literature data, and finite element analysis could be further conducted. The ratio of articular surface involved was positively associated with fragment height and fracture displacement, and negatively associated with fracture stability. These results indicate that the three-dimensional finite element models of distal tibial fractures were successfuly established. Fracture stability was associated with the ratio of articular surface involved and fragment height.

Objective To discuss the method and surgical technique in treatment of the displaced acetabular fracture.Methods The study involved 66 patients with displaced acetabular fracture treated operatively with reconstruction plates from August 2005 to June 2009.Based on the fracture typing,the surgical techniques including anterior ilioinguinal,posterior Kocher-Langenbeck,combined ilioinguinal and Kocher-Langenbeck and Y shaped approach were performed in 12,30,22 and 2 patients,respectively.Results The operation time was mean 3.4 hours(1.5-6.5 hours),with mean blood loss of 550 ml(range,350-1 200 ml).All patients were followed up for average 29 months(range,12-46 months).According to Matta evaluation standard,the reduction of acetabular fracture was anatomical in 34 patients,imperfect in 25 and unsatisfactory in seven.According to the modified Merled' Aubigne and Postel clinical evaluation standard,the clinical outcome was graded as excellent in 23 patients,good in 29,fair in eight and poor in six.Conclusion The factors key to successful operation include correct fracture classification,good approach anatomy,proficient technique of reduction and fixation,and reasonable perioperation measures.

BACKGROUND: A discussion is ongoing whether the elderly patients with femoral neck fractures should be treated with a non-cemented or a cemented hemiarthroplasty.OBJECTIVE: To evaluated the results of cemented hemiarthroplasty for femoral neck fractures in the patients older than 85 years with high-risk clinical problems and functional outcomes.METHODS: Thirty-two patients with femoral neck fractures were treated with cemented bipolar hemiarthroplasty. X-ray examination after operation was done at 1, 3 and 6 months and annually in all patients. The mean follow-up period was 2 to 5 years.RESULTS AND CONCLUSION: Medical complications occurred in five patients (16%) and four patients (25%) died within the follow-up period. Dislocation occurred in one patient (3%). None of the patients had heterotopic ossification. The mean Harris-hip score was 84. Cemented hemiarthroplasty can provide stability, security and good outcomes for the treatment of femoral neck fractures in elderly patients.

Objective To evaluate the efficacy and safety of two kinds of dosage of 5-aminosalicylic acid zinc enteric-coated capsule in treatment of active ulcerative colitis (UC). Methods The muhicentre, double blind, dosage reaction and contrast trial was conducted in six hospitals during March 2004 to Sep. 2004. One hundred and eight patients with UC were randomly allocated into the high dosage (n= 36, 1 g, bid) and the low dosage (n = 36, 0.5 g, bid) of 5-aminosalicylic acid zinc enteric-coated capsule groups, and the Olsalazine sodium group (n = 36, 1 g, tid) with a 8-week treatment. The efficacy and adverse events of 5-aminosalicylic acid zinc enteric-coated capsule were evaluated based on the clinical presentations and endoscopic findings. Results The clinical efficacy was 68.97% in high dosage group, 45. 45% in low dosage group and 62.86% in Olsalazine sodium group with no significant difference (P>0. 05). The endoscopic examination showed that the healing rate of UC in high dosage group and low dosage group was 51.72% and 21.21%, respectively, whereas the efficacy rate was 82.76% and 69.70% respectively. The results showed that high dosage was more effective than low dosage (P=0.023), but was similar to Olsalazine sodium (healing rate of 34.29% and effective rate of 88.57% ,P>0. 05). Diarrhea was main adverse event, which was accounted for 2.8% (1/36) in high dosage group and 2.8% (1/36) in the Olsalazine sodium group. There was no adverse event in low dosage group. Conclusions 5-aminosalicylic acid zinc enteric-coated capsule is an effective agent in treatment of UC, especially in high dosage. It is similar to Olsalazine sodium in treatment of UC, and has advantages in reducing medication times.

Objective To analyze the correlation of carotid artery stenosis(CAS)with postoperative cognitive dysfunc?tion(POCD)in patients who underwent off-pump coronary artery bypass grafting(OPCABG). Methods Between March 2014 and October 2014, a total of 157 patients who underwent OPCABG in our hospital were enrolled and divided into POCD group and non-POCD group according to their performance respondent to MMSE questionnaire survey conducted 5 days before operation. LOTCA questionnaire survey was conducted at the first day and 7th days pre-and post-operation re?spectively in order to investigate the influence of CAS on POCD in patients. Results The incidence of POCD was 30.6%(48 out of 157). Advanced age, diabetes,cultural level,carotid artery stenosis, Hb level after operation, score of LOTCA question?naire survey conducted before surgery,time of respirator and the time spend in ICU were significant predictive factors for POCD. However, multivariate logistic regression analysis showed that age, CAS and the time spend in ICU were independent risk factors for POCD, especially CAS(OR=5.078,95%CI:2.211-11.662, P<0.001). Patients with severe CAS suffer from a significant decline in cognitive function on space, time, action and ideation. Conclusion CAS is a predominant risk factor for POCD in patients undergoing OPCABG.
