ObjectiveTo explore the effect of percutaneous locking compression plate(LCP) internal fixation for distal tibial comminuted fracture.Methods35 patients of distal tibial Comminuted fracture were treated with percutaneous locking compression plate(LCP) internal fixation.ResultsAll patients were followed up for average 1.8 years(ranging from 1 to 2.5 years).All of cases have healed well,and the average bone healing was 14.6 weeks (ranging from 8 to 28 weeks ).All of them have no infection and no loosening or breakage of internal fixation.According to Mazur criterion,excellent effect 17 cases,good effect 16 cases,fair effect 1 case poor effect 1 case,94.3％ was excellent or good.ConclusionThe LCP internal fixation for distal tibial comminuted fracture have the advantage of less invasive,good internal fixation and bone union fastly and little complications.

Objective To study the mandibular anterior alveolar morphological characteristics of skeletal ClassⅢmalocclusion patients by CT quantitative research , which can provide guidances and indications for clinical skeletal Class Ⅲmalocclusion treatment and prevent iatrogenic complications , such as rootabsorption. Method 25 skeletal Class Ⅲ malocclusion patients during thepostpubertal were selected , three-dimensionalspiralCTscanning was applied to measure cortical and cancellousbonethickness around 6 mandibular incisors for analyzing the relationship between the bone mass and its anatomyaround the mandibular incisors roots. Results (1) The bone thickness around the lower anterior homonym teeth was basically symmetric in the skeletal Class III malocclusion. The labial thickness is a little less than the lingual side , gradually thickening along the root apical direction; (2) The area of mandibular incisors was inhomogeneous , and the 1/2 regional cancellous bone thickness of mandibular incisors was often lacked. Conclusion (1) The synchronous compensation of the teeth and alveolar bone is the significant feature of the skeletal Class Ⅲ malocclusion. (2) The responding regions ofthe alveolar bone in the 1/3 labial-cervical and root-tip may be the sensitive areas during the orthodontic treatment.

Objective To evaluate the clinical and MRI features of choroid metastatic tumors.Methods Clinical and MRI findings in 4 cases with choroid lung carcinoma metastasis based on pathological results were retrospectively analyzed.Results Lung metastatic carcinomas were the most common primary cancers metastasizing to the choroid all the 4 cases had a decrease of visual acuity rapidly.MRI showed diffuse or local thickness of bulbar wall,and revealed T 1 isointense and T 2 iso-or hyperintense signals.A mass extruding into the bulb was seen in 1 patient.Conclusion MRI of choroid metastatic carcinoma has characteristic manifestations,and MRI is an effective and useful technique for the diagnosis of this lesion.

Objective To investigate the method and result of repairing multi-fingers soft tissue defects using the dorsal metacarpal flaps with cutaneous branches as pedicle.Methods From February,2010 to January,2013,9 patients with multi-fingers tissue defects were treated with the 2nd,3rd,4th dorsal metacarpal flaps with cutaneous branches as pedicles.The area of flaps ranged from 1.2 cm × 2.5 cm to 2.5 cm × 5.0 cm.The donor sites were sutured with full thick skin graft.Results All flaps survived.After a followed-up of 8 months to 24 months(average 12 months),the texture and shape of the flaps were good and non-bloated.The flap sensibility as sessment were S3-S3+.The two-point discrimination testing were 10 to 13 mm (average 11.6 mm).The TAM score of range of motion was 60％ to 75％ of the healthy side.The skin graft of donor site were soft.Conclusion Procedure of dorsal metacarpal flaps with cutaneous branches as pedicles easy is a good method to repaire the soft tissue defects of muhi-fingers.
