Objective To compare the clinical effect of locking compression plate and anatomic plate fixation for Pilon fracture.Methods 68 patients with tibial Pilon fracture were selected and divided into two groups according to the random number table method,34 cases in each group,the observation group was given lock plus pressure plate fixation while the control group received anatomic plate for treatment,the clinically relevant indicators,treatment effect and occurrence of complications of the two groups were compared.Results The operation time of the observation group[(46.46 ±3.56)min],incision length[(5.25 ±0.75)cm],blood loss[(36.77 ±5.12)mL],plaster braking time[(13.23 ±1.77)d],fracture healing time [(12.42 ±1.43 )weeks],postoperative hospital stay [(9.89 ± 1.88)d]were less than or shorter than those of the control group [(68.76 ±4.45 )min,(12.78 ±1.54)cm, (84.75 ±8.65)mL,(20.30 ±2.43)d,(18.94 ±2.30)weeks,(15.67 ±2.64)d],the differences were statistically significant(t =6.834,9.455,7.488,6.591,7.033,8.210,all P <0.05).The excellent rate of the observation group was 94.12%,which was higher than 80.00% of the control group,the difference was statistically significant(χ2 =8.238,P <0.05).The postoperative complications occurred in the observation group was 5.88%,which was signifi-cantly increased to 17.65% in the control group,the difference was statistically significant(χ2 =7.657,P <0.05). Conclusion Compared with anatomical plate fixation,the locking compression fixation for Pilon fractures can shorten the healing time and reduce the incidence of complications,so it is safe and has significant advantages for the clinical application.

Objective To observe the effect of acupuncture on patients with vertebral-artery-type cervical spondylosis by means of transcranial Doppler sonography ~TCD) and brainstem auditory evoked potentials ~BAEP), and to explore the mechanism of acupuncture in treatment of cervical spondylosis by means of blood velocity and neuroelectrophysiology measurements. Methods Forty patients with vertebral-artery-type cervical spondylosis were divided into acupuncture treatment group ~20 cases) and routine treatment group ~20 cases). The TCD and BAEP were examined before the rehabilitation treatment and 2 week later. Comparing with the control group, the effect of acupuncture on the blood velocity and cerebral electrophysiology was analyzed. Results ~1)The total efficiency rates in the two treatment groups were 90% and 85%, respectively. The clinical heal rate was 45% in acupuncture group and 35% in routine group. There was no statistic difference with regard to the therapeutic effect and the length of treatment between the two groups. ~2)The blood velocity of vertebrobasilar artery ~VBA) in the patient group was decreased. The abnormal rate of TCD was 77.5% ~31/40 cases), characterized with the decrease of VBA. The abnormal rate of BAEP was 75% ~30/40 cases), characterized with brainstem abnormality type. ~3)The blood velocity in both groups was increased after treatment. Compared with the routine therapy group, the velocity of blood flow in vertebral artery in acupuncture treatment group was increased markedly ~P

Objective To investigate the clinical result, complication and influential factors of lyophilized and radiation-sterilized morselized allogeneic bone. Methods Between December 1995 and December 2000, 778 cases with implantation of bone allograft were performed. There were 188 females and 590 males with an average age of 37.2 years (range, 6-76 years). The lyophilized morselized allogeneic bone was processed according to American Association of Tissue Bank (AATB) standards and was sterilized by radiation. The bone allograft was rehydrated in fresh blood or in physiologic saline before implantation. The morselized allograft was used to fill defects attributable to various causes such as 84 bone tumors (10.8%), 551 fractures (70.8%), 143 joint fusions (18.4%). After implantation of the bone allograft, drainage was carried out for 2~3 days and antibiotics were used to prevent infection. The average amount of the allograft implanted was 24 g (range, 4-64 g). Results All patients were followed up clinically and radiographically. The minimum length of follow-up was 3 years with an average follow-up period of 59.7 months (range, 36-96 months), 722 allograft unions occurred at a mean of 4.5 months postoperatively (range, 3-8 months). There were 137 complications, included 44 of wound effusion (5.65%), 29 of delayed wound healing (3.72%), 2 of profuse liquid accumulation (0.26%), 43 of fracture non-union (5.52%), 4 of tumor recurrence (0.51%), 9 of fusion failure (1.15%) and 6 of fracture (0.77%). Estimated by the combined Mankin and Komender standards, 688 (88.44%) patients were satisfied with their outcomes while the other 90 (11.56%) patients were dissatisfied. Conclusion The lyophilized and radiation-sterilized morselized allograft is of good tissue compatibility and able to promote bone formation, it can be considered as a convenient, safe, and available material for bone transplantation. The important factors affecting allograft healing are the mechanical stability in the recipient region, local blood supply for the site of grafting and the surgical technology. The major complications of allograft are late infection and re-fracture.

The pain was evaluated with visual analogue scale (VAS) before and after treatment.ResultsCompared with traditional treatment, the floating acupuncture can relieve pain rapidly after 15 min and 1 d of treatment. ConclusionThe floating acupuncture shows preferable clinical curative effect to patients with the processus transverses of vertebrae lumbales Ⅲ syndrome.

Objective To explore the comprehensive approach of rhinoplasty using autologous costal cartilage,and to observe the outcome and summarize the possible complications.Methods A 6-7 cm long costal cartilage was taken out mostly from the 6th or 7th rib and then divided into several parts and shapes.A lancet shaped piece was used for dorsal augmentation,several cartilage bars for collumellar elevation and nasal tip elongation.Comprehensive structural rhinoplasty was then done with open rhinoplasty incision.Results 52 patients were treated with this method and satisfying aesthetic contouring of the nasal tip and dorsum was achieved.Among these patients,no such complications as implant extrution or dislocation,cartilage distortion,pneumothorax,hemothorax,infection or hemotoma were observed.The scar on the donor site was not obvius.Conclusions Costal cartilage can meet the demands of patients who consider prosthesis as an unacceptable option.For secondary revision rhinoplasties,costal cartilage provides sufficient materials to ensure a promising outcome with lower risk of infection and other complications.

Objective To evaluate and compare liver regeneration between normal donors and recipients at the different stages after right lobe adult living donor liver transplantation (LDLT) using MSCT.Method Sixty-eight living donors and 63 recipients without complications were included in this study.We did CT volumetric measurement of the liver by using IQQA-Liver workstation.The relationship between graft volume measured by preoperative MSCT and intraoperative actual graft volume was evaluated.The liver regenerative ratio at different stages of donors and recipients after LDLT was calculated and compared.Result Preoperative measurement of total liver and grafts resulted in a mean volume of (1366.99 ± 234.75) cm3 (standard deviation) and (862.73 175.94) cm3 (VCT-right),respectively.Intraoperative volume of the grafts was (654.46 ± 151.23) ml (Vintraop).Corresponding pre-and intraoperative data were correlated significantly each other (r =0.795,P=0.000).Vintraop can be calculated with the equation:Vintraop =64.949 + 0.683 VCT-right.There was significantly difference in LRR between donors and recipients at 0.5,1,3 and 6 months after LDLT (P＜ 0.05).Conclusion The patterns of normal liver regeneration between donors and recipients after LDLT are different.The liver of donors regenerates more significantly and quickly than recipients.Liver volumetric measurement by using MSCT is a valid modality to evaluate liver regeneration after LDLT.

Objective To evaluate donor remnant liver regeneration and influencing factors at different stages after right lobe adult living donor liver transplantation (LDLT) using multi-slice spiral computed tomography (MSCT).Methods 68 living donors were included in this study,We did CT volumetric measurement of the liver by using IQQA-Liver workstation.Liver regenerative ratio (LRR) at different stages of donors after LDLT were calculated and compared,correlation coefficient and stepwise regression analysis were calculated.Results The difference between LRRs at different stages after LDLT were significant (F =3.323,P =0.009),there were significant difference between LRR of 7-day and 1-month,3-month (respectively t =-2.065,-2.214,all P ＜ 0.05).The inclusion of middle hepatic vein and donor gender had no influence on LRR (respectively t =0.600,-0.622,1.464,0.926,-1.228,0.624,-0.688,0.131,all P ＞ 0.05).There were negative correlation between the remnant liver volume and LRRs (P ＜ 0.05).Conclusions MSCT is a valid modality to evaluate remnant liver regeneration after LDLT.Most evident remnant liver regeneration occurs in early stage after adult LDLT.

Objective To evaluate the impact of donor age on graft short-term outcome after right lobe adult living donor liver transplantation (LDLT).Method Thirty living recipients were divided into 2 groups according to donor age:older donor group (O group,donor age ＞50,n =5) and younger donor group (Y group,donor age ＜30,n =25).Alanine transarninase (ALT),aspartate transaminase (AST),total bilirubin (TB),prothrombin time (PT) on the postoperative day 1 to 5 and graft liver regenerative ratio (LRR) on the postoperative month 0.5,1,3,and 6 between 2 groups were determined and compared.Result TB on postoperative day 1,2,3,4 and 5 was significantly higher in O group than in Y group there were significant differences between two groups (P＜0.01).There was no significant difference of other liver function parameters 2 groups (P ＞ 0.05).There was no significant difference in LRRs on the postoperative month 0.5,1,3 and 6 months postoperatively between 2 groups after LDLT (P＞0.05).Conclusion Although allografts from older donors in LDLT have prolonged jaundice than those of their younger counterparts,after strictly preoperative evaluation,donor age has little effect on short-term outcomes of graft after LDLT.
