ABSTRACT
Objective@#To observe the clinical efficacy of self-made one-fourth tubular hook plate used in the fixation of comminuted fractures of acetabular posterior wall.@*Methods@#The clinical data of 21 patients with comminuted fracture of acetabular posterior wall were retrospectively analyzed who had been treated by fixation with our self-made one-fourth tubular hook plate from June 2015 to September 2017 at Deparment I of Orhthopaedics, The Second People's Hospital of Anhui Province. They were 12 males and 9 females, aged from 20 to 59 years (mean, 38.5 years). The time from injury to surgery ranged from 3 to 6 days (average, 4.5 days). All the fractures were fixated with our self-made one-fourth tubular hook plate via the Kocher-langenbeck approach. Depending on the fracture fragments, the hook plate was cut out obliquely through the 3rd or 4th hole and the sharp end of the plate was bent into a small hook to hold the fragments. Only the hook plate was used in 6 cases and an additional construction plate in the other 15 cases. The postoperative reduction, functional recovery of the affected hip and complications were recorded.@*Results@#The follow-up averaged 13 months (from 8 to 32 months). Intermuscular venous thrombosis occurred in one patient and sciatic nerve contusion was observed intraoperatively in one patient with sciatic nerve injury. According to the improved Matta criteria, the fracture reduction was rated as excellent in 16 cases, as good in 4 and as poor in one, giving a good to excellent rate of 95.2%. The fractures united after an average of 7.5 months (from 6 to 12 months). According to the improved Merle d'Aubigné and Postel scoring system, the hip function at the final follow-up was excellent in 14 cases, good in 3, fair in 2 and poor in 2, giving a good to excellent rate of 81.0%. Follow-ups revealed traumatic arthritis in 3 cases, femoral head necrosis in 2 cases and ectopic ossification in one.@*Conclusion@#Our self-made one-fourth tubular hook plate is simple, economical and effective because it can provide easy and rigid fixation of the comminuted fractures of acetabular posterior wall, leading to fine therapeutic effects.

ABSTRACT
BACKGROUND:Recent studies have demonstrated that surgical trauma leads to lipid peroxidation in erythrocytes.However,injured erythrocytes play an important role in thrombosis following replacement.OBJECTIVE:To evaluate the influence of artificial total knee replacement on the lipid peroxdation in erythrocytes,and the prophylactic treatment of vitamin E and fructose 1,6 diphosphate(FDP)on it.DESIGN,TIME AND SETTING:Contrast clinical study,which was carried out in the Department of Otthopaedics,Affiliated Hospital of Nantong University from January 2003 to June 2006.PARTICIPANTS:Sixty patients with knee osteoarthritis who underwent artificial total knee replacement by anesthesia of epidural block were divided into four groups,including control group,vitamin E group,FDP group and vitamin E+FDP group,with 15 cases in each group.METHODS:Vitamin E was orally taken in the vitamin E group three days before replacement,three times a day,100 mg for each.The administration was performed until the surgical morning.Thirty minutes after the operation,FDP(10 g)was intravenously dripped in the FDP group.Additionally.vitamin E was also orally taken in the vitamin E+FDP group three days before replacement,three times a day,100 mg for each;on the surgical morning,FDP(10 g)was intravenously dripped on the first 30minutes.Blood samples were taken for biochemical determination before and after the operation at 1,3,5,and 7 days.MAIN OUTCOME M[EASURES:Corltents of malonaldehyde(MDA)and cuprum/zincum/superoxide dismutase (Cu-Zn-SOD)in the erythrocytes.RESULTS:MDA level in the vitamin E group and FDP group was significantly higher than that in the vitamin E+FDP group before and 5 and 7 days after replacement(P<0.05);while,Cu-Zn-SOD level was significantly lower(P<0.05).Otherwise,there were no significant differences in vitamin E+FDP group before and after replacement(P>0.05).CONCLUSION:The artificial total knee replacement can enhance lipid peroxidation and decrease antioxygen capability.However,the combination of vitamin E and FDP can prevent and relieve lipid peroxidation and antioxygen capability after replacement.
