OBJECTIVE: To retrospectively evaluate the effect of locking compression plate (LCP) combined with scaled cancellous bone graft on postoperative nonunion of humeral shaft fracture. METHODS: A total of 19 cases with postoperative nonunion of humeral shaft fracture were collected from Department of Orthopaedics, Affiliated Hospital, Xiangnan University between August 2005 and January 2009. There were 12 males and 7 females, aging 28-59 years with the mean age of 36 years. All patients were treated with LCP fixation combined with scaled cancellous bone graft. The key points of the operation were as follows: beck-median or lateral approach, protection of the radial nerve and ulnar nerve, removal of the cicatrix, reopening of humeral canal, and limited periosteum striping. For minimally invasive plate osteosynthesis technique, length of LCP was appropriate, 3-4 locking screws at least were used on either stump, and double cortices were penetrated with locking screws and treated with scaled cancellous bone graft. RESULTS: All the fractures healed with a mean period of 7.2 months (from 6 to 8 months). Two cases showed temporary radial nerve palsy after the operation, which gradually recovered 3 and 6 weeks, respectively after appropriate treatment. Shoulder and elbow functions were somewhat impaired in 7 cases, but the dysfunction could not influence daily living. Infection, screw loosening, blade plate breakage, and other complications were not found. CONCLUSION:The integrity of locking screws and plate prevents screw breakage and plate loosening. The combination of autoallergic cancellous bone graft and scaled decorticating technique can improve healing of humeral shaft fracture.

Objective To analyze the abnormal detectable rates of different kinds of blood test indexes before and after treatment in the patients with snake bite and to probe into the change condition of these indexes after different snake bite .Methods The inpa‐tients with clearly diagnosed what kind of snake bite in the past two years were selected as the research subjects .The multiple blood test indexes were determined before and after treatment in these patients .The abnormal detectable rates of these indexes were ana‐lyzed and compared among various snake bite patients .Results The different kinds of snake bite all could cause the different de‐grees of changes in some detection indexes among partial patients .Specially ,the detectable rates of WBC ,PT ,APTT ,TT ,D‐D ,CK , CK‐MB ,LDH ,Urea ,Cr and Cys‐C increase and PLT and Fbg decrease caused by viper bite were apparently higher than those caused by other kinds of snake bites (P<0 .05) .The detectable rates of CO2 increase and K+ decrease in the coral snake bite were apparently higher than those in trimeresurus gramineus ,cobra and viper bite (P<0 .05) .Conclusion Because the snake species and toxicities are different in the various snake bites ,so the caused changes and the abnormal detectable rates of blood test indexes also are different .

Objective To explore the anatomic characteristics of the peroneal perforator branches and its clinical application as vascularized flap transfer. Methods Twenty fresh cadaver specimen with 40 sides lower limbs were used in this study.Lead oxide gelatin was injected to the whole body,lower extremity radiaograph, spiral CT scan was then used to construct three demention visual model. The peroneal artery and its perforators were dissected,number of peferators,distance to fibular head,diameter and the length of the vascular pedicles were measured and analyzed. From July 2005 to October 2009, forty-three cases with skin defects were performed vascularized transfer in our study,surviving rate and postoperative function were followed up for 6 months to 2 years.Results Perforators were seen most at (9.80 ± 0.93)cm,(13.40 ±0.90) cm,(17.20 ± 1.13)cm,and (21.30 ± 0.77)cm beneath the fibular head with the artery branch diarneter(1.33 ± 0.39) mm,(1.30 ± 0.46)mm,(1.17 ± 0.30)mm,and (1.22 ± 0.23)mm,respectively,while the pedicle length was (5.87 ± 0.73)cm,(5.83 ± 1.73)cm,(5.44 ± 1.09)cm,and (5.10 ± 1.93) cm respectively.In clinic,42/43 free flaps survived.Postoperative outlook were satisfied except in 7 cases,the flaps looked bulky and needed secondary revision.All the donor calves showed good apperaence and function.Conclusion There are 4 regular perferators in lateral calf, while perforators in the middle 1/3 are bigger with relatively longer vascular pedicles which are appropriate for vascularized transfer.

BACKGROUND:Active surgical treatments are preferred for elderly hip fractures. Individual fixation method is chosen according to fracture site, type, age and whether there are basic diseases in internal medicine, which plays an important role in the successful treatment of elderly hip fractures.
OBJECTIVE:To explore the effects of optimized surgical treatment on osteoporotic hip fracture in the elderly.
METHODS: Totally 176 patients with osteoporotic hip fracture were treated by different methods between January 2000 and January 2012, including 63 males and 113 females, with a mean age of (76.7±6.3) years. Out of the 84 cases of interchanteric fracture, seven cases were treated with conservative methods, 34 cases were treated with dynamic hip screw internal fixation, 18 cases were treated with cannulated screw internal fixation, seven cases were treated with anatomical plate internal fixation, 12 cases were treated with bipolar femoral placement, and six cases were treated with total hip arthroplasty. Out of the 92 cases with femoral neck fractures, 40 cases were treated with bipolar femoral placement, 37 cases were treated with total hip arthroplasty and 15 cases were treated with cannulated screw internal fixation. Modified Harris hip function scores were used to evaluate the therapeutic effects of different treatment methods. Complications were observed.
RESULTS AND CONCLUSION:Seventy-six cases of interchanteric fractures and 85 cases of femoral neck fractures were fol owed-up for 8-26 months with an average of (5.7±1.3) months. Three cases suffered from post-operative infection, and one case died due to cardio-pulmonary failure in 10 days after operation. Both intraoperation and postoperative complications included femoral head cutting, intraoperative fracture, internal fixation and prosthetic loosening, postoperative fracture, avascular necrosis of femoral head, coxa vara, legs shorten, and delayed fracture healing. The incidence rates of complications in patients undergoing bipolar femoral placement and total hip arthroplasty were significantly lower than those treated with conservative methods, dynamic hip screw internal fixation, cannulated screw internal fixation, and anatomical plate internal fixation (P<0.05). The outcomes of the treatment according to Harris scoring criterion were better in patients treated with bipolar femoral placement and total hip arthroplasty than in patients treated with conservative methods, dynamic hip screw internal fixation, cannulated screw internal fixation, and anatomical plate internal fixation (P<0.05). No significant differences were found in the incidence rate of complications and Harris scores among patients treated with conservative methods, dynamic hip screw internal fixation, cannulated screw internal fixation, and anatomical plate internal fixation (P>0.05). No significant differences were found in the incidence rate of complications and Harris scores between patients treated with bipolar femoral placement and total hip arthroplasty (P>0.05). These findings indicate that the treatment of osteoporotic hip fracture in the elderly can achieve satisfactory results if the comprehensive therapies are given. Bipolar femoral placement and total hip arthroplasty are preferred for elderly femoral neck fractures.
