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 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.

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.
