Objective To observe the clinical efficacy of relatively proximal humeral locking compression plate( LPHP) with the traditional plate for treatment of proximal humeral fractures .Methods The proximal humeral fractures in patients with 58 cases,the patients were divided into two groups ,the treatment group of 32 cases of locking compression plate in the treatment of T plate ,clover plate in the treatment of 26 patients of the control group received traditional.According to the Neer score compared with two groups of patients with postoperative recovery and compli -cations.Results All the 58 patients for 11 ~15 months of follow-up,the treatment group found no fracture ,fracture nonunion,screw and plate humeral head necrosis ,4 cases of shoulder pain was limited;15 cases of excellent score Neer function,good in 12 cases,5 cases,the excellent and good rate was 84.4%.The control group had 3 cases,2 ca-ses of screw loosening of plate fracture ,3 cases of nonunion ,2 cases of humeral head necrosis ,7 cases of shoulder pain limited.6 cases of excellent score Neer function ,good in 9 cases,3 cases,poor in 8 cases,the excellent and good rate was 57.7%.There was significant differences between the two groups (χ2 =5.113,P <0.05) excellent rate. Conclusion LPHP exact treatment of proximal humeral fractures has fewer complications , which can help patients with early rehabilitation exercises .

Objective: The related literatures on supra acetabular spinal pedicle screws and a subcutaneous connecting rod (INFIX) in recent years was reviewed, and the overall prognosis was analyzed by meta analysis. Methods: literatures were obtained by searching the PubMed, Google Scholar, and Wanfang Full-text Database according to the criteria of inclusion and exclusion. The two members independently screened the qualified literature, evaluated the quality of the literature and extracted the data information. The data information includes demographic and surgical information, main results and secondary results. A large number of data in the selected articles were analyzed and summarized by meta. Results: A total of 20 studies were included, including 567 patients. The clinical results were evaluated by Majeed standard in 6 articles, of which 5 articles described the number of excellent and general prognosis, including 185 patients. The excellent and good prognosis rate was 91% (95%CI: 80%-103%) by meta analysis. The general prognosis rate was 9% (95%CI: 3%-14%). Among the prognostic complications, the incidence of lateral femoral cutaneous nerve damage and heterotopic ossification was higher, and the incidence of other complications was less than 5%. There were 13 articles about the complications of ectopic ossification, of which 1 did not mention the specific number of asymptomatic heterotopic ossification, and the remaining 12 included 424 cases, including 132 cases of ectopic ossification. The incidence of ectopic ossification was 26% (95%CI: 11%-40%). Among the 567 cases, obvious symptoms of lateral femoral cutaneous nerve injury were reported. The patients with lateral femoral cutaneous nerve injury accounted for 25% (95%CI: 17%-32%), and the temporary nerve damage was found in 124 cases. The incidence of temporary agitation after subgroup analysis was 21% (95%CI: 14%-28%). Five articles mentioned the manifestations of postoperative femoral nerve damage, including 10 patients, the incidence of femoral nerve damage was 3% (95%CI: -1%-6%). A total of 18 articles on surgical site-related infections were reported, including 534 patients, of which 15 were infected, with an infection rate of 3% (95%CI: 2%-4%). 19 articles clearly reported the failure of internal fixation after INIFX operation, including 32 patients who needed reoperation for different reasons. The failure of internal fixation was 3% (95%CI: 2%-4%). A total of 585 cases of fracture non-prognosis data were reported, of which 473 cases were cured and 3 cases had bone nonunion. The non-union rate of fracture was 3% (95%CI: 1%-5%). Conclusion After InFix pelvic surgery, the patient's clinical follow-up prognosis score and imaging findings showed that the postoperative recovery was good, and the new technique also avoided the inconvenience and postoperative complications caused by many traditional pelvic external fixation techniques. However, it was also found that the lateral femoral cutaneous nerve damage and the incidence of heterotopic ossification were also higher.
