Objective To study the mechanics situation of proximal femoral locking plate internal fixation after dynamic hip fixation in-tertrochanteric fracture. Methods Totally 10 couple of elderly proximal femur specimens were collected and intertrochanteric fracture model were prepared. Fixation material was removed after dynamic hip screw fixation. The left sides were collected as control group and given anti-rotation intramedullary nail internal fixation, while the right side were collected as observation group and given proximal femoral locking plate internal fixation. Then vertical displacement, axial stiffness and rotational stiffness under different loads were compared. Results Under dif-ferent loads, femoral bone vertical displacement and femur tuberosity vertical displacement in the observation group were both significantly shorter than those in the control group (P<0. 05), and femoral bone and femur tuberosity axial stiffness and rotational stiffness in the observation group were significantly higher than those of the control group (P<0. 05). Conclusion Proximal femoral locking plate internal fixation can improve stress load and enhance axial stiffness and rotational stiffness, and it's an ideal material for refracture fixation model after dynamic hip fixation intertrochanteric fracture.

Objective To investigate the clinical features,diagnosis and treatment of appendix tumor.Methods The clinical data of 58 cases with primary appendiceal tumor were analyzed retrospectively.Results In the 58 cases clinical presentation mimicked acute appendicitis in 22 cases,chronic appendicitis in 15 cases,appendiceal abscess in 12 cases,intra-abdominal mass in 7 cases,and gastrointestinal perforation in 2 cases.Primary appendiceal tumor was diagnosed intraoperatively by intraoperative frozen histopathological examination in 10 cases,and the diagnosis was made by postoperative histopathological examination in the other 48 cases.There was appendiceal carcinoid in 40 cases,adenocarcinoma in 6 cases,mucocele in 2 cases,mucous adenocystoadenoma in 5 cases,pseudomyxoma peritonei in 2 cases,malignant neurilemmoma in 1 case,and malignant lymphoma in 2 cases.Surgical procedures included appendectomy in 6 cases,ileocecal resection in 8 cases,and right hemicolectomy in 44 cases (including right hemicolectomy and intraperitoneal chemotherapy with 5-FU 1 000 mg for pseudomyxoma peritonei in 2 cases).Radical resection was achieved in 55 cases and palliative resection in 3 cases.The 2 cases with pseudomyxoma peritonei died of tumor recurrence at 36 months and 54 months after operation respectively.All the 5 cases of adenocystoadenoma and 2 cases of appendix cyst survived without an evidence of recurrence.7 of 49 cases of malignant appendiceal tumor suffered recurrence postoperatively,the recurrence rate was 14％,which included liver metastasis in 4 cases and intraperitoneal recurrence in 3 cases.The 1,3,5-year survival rates of malignant appendiceal tumors were 100％ (49/49),92％ (35/49) and 80％ (39/49),respectively,which were 100％,98％ and 92％ for carcinoid,and 100％,67％ and 33％ for adenocarcinoma,respectively.Conclusions The preoperative diagnosis of primary appendiceal tumor is very difficult,the intraoperative frozen histopathological examination is helpful for diagnosis,the prognosis of appendiceal carcinoid is fair after resection.
