Objective To investigate the clinical characteristics of unstable pelvic fractures and to find out an alternative for the treatment. Methods From October 2000 to June 2004, fifty-six patients with unstable pelvic fractures were treated by open reduction and pelvic-reconstructed plate fixation to recover the anatomical structure of pelvis and acetabulum. According to Tile classification, 33 cases were type B (15 cases were Tile B1, 11 cases were Tile B2, 7 cases were Tile B3); 23 cases were type C (10 cases were Tile C1, 8 cases were Tile C2, 5 cases were Tile C3). Results The 56 cases were followed up 12 to 68 months(26 months in average).All cases with fractures got healed during 3 to 6 mouths. According to the Majeed evaluation, 40 cases were excellent, 11 cases were good, 4 cases were fair, and only one case was a failure. The rate of excellency and goodness was 91.07%.The pelvic abnormity was rectified; partial patients felt light pain in iliac scar. Conclusion The choice of the proper operative approach and pelvic-reconstructed plate fixation by allowingfor fracture classification is a good and dependable means for treating unstablepelvic fractures.
Objective To discuss the surgical method and effect of repair of damage injury in the hands. Methods Of the 29 cases, 22 were males, 7 were females. Their ages ranged from 15 to 31.The size of defect areas ranged from 18 cm×8 cm to 22 cm×10 cm .Along with dorsalis pedis flap, lateral hemi-pulp flap was takenfrom great toe and first web space flap. The second toe was taken from one footto reconstruct the thumb, second and third toe from another foot was used to reconstruct two fingers. The dorsalis pedis flaps were used to cover palm and dorsum of hand. The lateral hemi-pulp flaps from great toe and first web space flapswere used to reconstruct first web space of hand.Results With the 58 combined flaps, 29 thumbs and 58 fingers were reconstructed. Followups was done for 1 to 8 years.All the thumbsand fingers of 29 hands were reconstructed. Their shape and function were well recovered. Conclusion This new surgical method is effective inpreserving the function of injured hand. The function of the injured hands can be preserved by this surgical method, therefore this method is optimal.

Objective To explore better approach of resecting tumoraround the anterior skull base and reconstructing the anterior skull base.Methods In November 2004, a 49-years-old male patient with intracranial recrudescent adenoid cystic carcinoma in the anterior cranial fossa was treated using modified transcranial approach. Neurosurgeon and rhinolaryngologist cooperated to excise the tumour completely, and to reconstruct anterior skull base using the pedicle periosteum temproal musculofascial flap(15 cm×10 cm) andthe pedicle flap of aponeurosis of occipitofron talis muscle and muscular fasciae（10 cm×6 cm）.Results After operation, the wound healed by first intention. Complication, such as infection and cerebrospinal rhinorrhea, did not occur. The patient was discharged 10 days after operation, and was followed up for 8 months, no local recurrence were investigated and no scar formed over the face.Conclusion The modified transcranial approachis a relatively novel exposure that enables the skilled cranial base surgeon tosafely resect many malignant lesions previously and to reconstruct the defect of anterior skull base together.
目的:研究距骨骨折螺旋CT轴扫、多平面(MPR)和三维(3D)重建图像的特点及其临床意义。方法:收集距骨骨折患者术前螺旋CT资料12例,同时进行了MPR和3D重建图像。着重分析距骨骨折线的走行、与关节面的关系、关节面塌陷程度等,并评价轴扫、MPR和3D重建图像的优势。结果:在12例距骨骨折者骨踝关节受累7例。MPR和3D重建图像可直观显示骨折详细情况。结论:螺旋CT轴扫、多平面和三维重建图像相结合,可更好显示距骨骨折的情况,能为临床术前诊断和治疗提供有价值的影像信息。
Objective To evaluate the effect of reconstruction withautograft implantation in total hip arthroplasty(THA) with regional acetabular deficiency. Methods From 1991 to 2000, 39 cases of THA with acetabular deficiency were conducted. Autogenous bone implantation was used to reconstruct the deficient acetabulum. Of the 39 patients, 25 were males and 14 were females. The age ranged from 34 to 62(45.2 on average). There were21 cases of developmental dysplasia resulted deficiency, 14 cases of fracture of femoral neck complicated with head necrosis(10 hips) and fracture of acetabulum(4 hips). The resected femoral heads or autologous ilium were made the wedgeshaped graft and implanted into the deficient acetabulum, which included 12 cases with cement THA and 27 with cementless THA.Of all the cases, 24 were followed up 2 to 10 years(6.7 years on average). Harris scores before operation were 18 to 50(38.1 on average). Results The limbs were lengthened by 2.4 cm on average. No serious complications were observed in these patients. Comparedwith the scores before the operation, the average Harris scores after the operation were 92.1(Plt;0.01)and 86.3(Plt;0.05) in the one-year and the latest follow-up respectively. The rates for the good were 91.7% and 83.3% in the one-year and the latest follow-up respectively.Conclusion The acetabular reconstruction with autograft in THA will bring better stability in those patients with acetabular deficiency. It is of significance in maintaining a long-term function in the replaced hip.
Objective To introduce the treatment and clinical result of reconstructing femoral artery with external jugular vein graft. Methods From June 2002 to April 2006, 22 cases of femoral artery defects caused by pseudoaneurysm resection, were reconstructed withexternal jugular vein graft by microsurgical technique. There were 20 males and2 females, aging 25-46 years (mean 31.2 years). The length of femoral artery defects was 5-9 cm, with an average of 6.8 cm. The location was left in 14 cases and right in 8 cases.Results Ten cases achieved healing by the first intention, and 4 cases by the second intention. The other 8 cases need the regional flap repair because the wound splited open and became ulcer. Femoral artery defects were reconstructed successfully and the pulse of dorsal arteries of foot could be felt except 1 case of bleeding of anastomotic rupture. Eighteen patients were followed up 1-30 months, and no pseudoaneurysm recurred. Color ultrasound Doppler detection showed that the external jugular veins took place of the femoral artery defects in 12 cases. Conclusion External jugular vein is stable at anatomy and easy-to-obtain. Its calibre is close to that of the femoral artery. It can be used for reconstructing femoral artery defects as the vein material. The operation is easy and the clinical result is sure.
