OBJECTIVETo study the therapeutic efficacy of manipulative reduction and percutaneous pin fixation for the treatment of severely displaced distal tibial fractures in children.
METHODSFrom May 2009 to December 2012,56 children with severely displaced distal tibial fractures were analyzed, who had been treated with manipulative reduction and percutaneous pin fixation. Preoperative fractures were confirmed as severely displaced fractures by X-ray apparatus. There were 33 boys and 23 girls,ranging in age from 3 to 14 years, with an average of 10.1 years. All the fractures were closed without vascular or nerve injuries. According to the bone fracture type, under C-arm fluoroscopy, functional reduction was achieved by manipulative reduction. The fractures were fixed with percutaneous pins. Postoperative X-ray confirmed the functional reduction. Follow-up indexes were recorded: intra-operative and postoperative complications,postoperative radiographic examination, lower extremity length and range of ankle motion. Ankle score system of Teeny was used to evaluate ankle function.
RESULTSAll the patients were followed up, and the duration ranged from 3 to 46 months, with an average duration of 19.4 months. According to the Teeny score standard, 35 patients got an excellent result, 7 good and 3 fair. Pin track reaction was found in 4 cases. The X-ray showed all the fractures healed without shortening deformity or epiphyseal arrest at early stage. All the patients could participate in the normal physical activities, having a normal range of motion and excellent strength of the ankle joint.
CONCLUSIONThe method of manipulative reduction and percutaneous pin fixation is a safe and convenient treatment for severely displaced distal tibial fractures in children. It has several advantages as follow: micro-trauma, tiny tissue damage, firm fixation, and the patients can exercise the function of ankle early, suggesting that it is an effective treatment method.

OBJECTIVETo compare efficacy of unilateral external fixators and locking compression plates in treating type C fractures of the distal radius.
METHODSFrom January 2009 to June 2010, 76 patients with distal radius fracture were treated with LCP and external fixators, 54 patients were followed up. Among them, 29 cases were male and 25 cases were female with an average age of 45.31 (ranged, 24 to 68) years old. There were 29 patients in LCP group. According to AO classification, 8 cases were type C1, 7 cases were type C2 and 14 cases were type C3. There were 25 cases in external fixators group. According to AO classification, 6 cases were type C1, 8 cases were type C2 and 11 cases were type C3. Radial height, volar tilt and radial inclination were compared, advanced Gartland-Werley scoring were used to assessed wrist joint function after 6 and 12 months' following up.
RESULTSTwo cases were suffered from nail infection in external fixators group. Fifty-four patients were followed up from 12 to 24 months with an average of 21.3 months. Radial height was (9.60 +/- 0.72) mm, volar tilt was (9.55 +/- 0.80) degrees and radial inclination was (21.40 +/- 0.78) degrees in LCP group,while those were (9.40 +/- 0.70) mm, (9.47 +/- 0.71) degrees and (21.20 +/- 0.73) degrees in external fixtors group, and with no statistical significance (P>0.05). Advanced Gartland-Werley score after 6 months' following up was 3.31 +/- 1.17 in LCP group, 5.56 +/- 1.58 in external fixtors group, and with significant difference (t=-5.99,P<0.05); after 12 months' following up, advanced Gartland-Werley score was respectively 2.66 +/- 1.01 and 3.08 +/- 1.00, but with no statistical meaning (t=-1.55, P>0.05).
CONCLUSIONLCP and external fixtors can receive good curative effects in treating type C distal radius fracture, and LCP can obtain obviously short-term efficacy, while there is no significant difference between two groups in long-term results. For serious distal radius comminuted fracture which unable to plate internal fixation, external fixators is a better choice.

Objective To explore the clinicopathological characteristics of early gastric cancer (EGC),surgical treatment, and prognosis in elderly patients. Methods The clinicopathological and follow-up data in 83 elderly patients with EGC treated by gastrectomy from 1989. 8-2004. 8 were studied retrospectively. Results All of 83 patients were resectable, and there was no operative death nor surgical complications. The 5-, 10-, and 15- year survival rate was 98%,95%,and 92%, respectively. Sixty-one cases (74%) were mucosal cancer without lymph node metastasis, 22 cases were submucosal cancer with node metastasis in 4 cases. 7 cases were multiple primary carcinoma. Conclusions Local resection and partial gastrectomy are not suitable for multiple primary carcionoma in elderly patieats with EGC. Subtotal gastrectomy, and total gastrectomy should be the procedure of choice when foci were scattered about. Lymph node metastasis,multiple primary cancer foci and invasion of submucosal layer are all among factors impacting postoperative prognosis.
