ObjectiveTo investigate the effects of minimally invasive key-hole drainage for treating acute subdural hematoma.MethodsThirty-five patients with acute subdural hematoma treated by key-hole drainage were retrospectively analyzed.CT-oriented key-hole drainage was performed to aspirate,liquefy and drain hematoma.The transfixion pin was removed after hematoma was basically cleared within 1 to 3 days.ResultsHematoma volume decrease was greater than 80％ by follow-up CT 24 hours postoperatively.Headache and vomiting in the preoperative conscious patients were significantly relieved after key-hole drainage.Glasgow Outcome Score (GOS) was 5 points in 16 patients,4 points in 15 and 3 points in four six months postoperatively.One patient was complicated with hydrocephalus and two with epilepsy.ConclusionsKey-hole drainage with disposable transfixion pin selective employed for patients with acute subdural hematoma is effective and has few complications.The treatment notably improves prognosis of the patients.

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 .
