自固化磷酸钙人工骨修复骨缺损的临床应用

目的:探讨自固化磷酸钙人工骨(CPC)填充修复骨缺损的临床效果。方法:骨缺损94例,男59例,女35例;年龄11~72岁,平均39.4岁。骨缺损部位:胸腰椎38例,跟骨25例,胫骨15例,股骨7例,肱骨近端3例,桡骨远端5例,近节指骨1例。骨缺损原因:骨折塌陷复位后骨缺损63例,骨髓炎20例,骨囊肿6例,骨纤维异常增殖症4例,内生软骨瘤1例。骨缺损范围为1cm×1cm~4cm×20cm,用CPC填充修复,CPC充填量为3~42g,其中单纯CPC填充修复74例(胸腰椎骨折行椎体成形38例,骨折复位后空腔充填25例,良性骨肿瘤病灶刮除后充填11例),载药CPC填充修复骨髓炎20例。结果:所有患者均获随访,随访时间14~48个月,平均29.6个月。全部患者术后未见过敏或毒性反应,无皮疹或高热,血钙、磷、碱性磷酸酶均正常,切口无瘙痒感。随访时X线片显示,植入CPC与宿主骨接触紧密,界面处未见间隙存在,骨缺损处的解剖形状完全或大部分恢复,未见脱落现象,随访时部分患者CPC部分降解成骨。9例发生术后伤口渗出,为淡黄色清亮稀薄分泌物,细菌培养阴性,经换药后伤口愈合良好。结论:CPC填充修复骨缺损安全有效,并发症少,是理想的骨替代品,载药CPC是治疗骨髓炎的理想方法。

鞘内注射吗啡加可乐定对切口痛大鼠脊髓背角蛋白激酶A催化亚单位表达的影响

Objective To observe the effect of intrathecal clonidine plus morphine on expression of protein kinase A (PKA) catalytic subunit in the spinal dorsal horn in a rat model of incisional pain. Methods Eighty male Sprague-Dawley rats were divided randomly into five groups: sham group, control group, pre-incisional morphine 2.5 μg group, pro-incisional clonidine 5 μg group and preincisional morphine 2.5 μg plus clonidine 5 lag group (n=16). lntrathecal catheter and the model of incisional pain were pro-duced according to Yaksh and Brennan's described method respectively. Changes of pain behavior were assessed by mechanical with-drawal threshold (MWT) and thermal withdrawal latency(TWL). The expressions of PKA catalytic subunit in the spinal dorsal horn were assessed by immunohistochemical method and western blotting analysis. Results Compared with sham group, MWT and TWL in control group were decreased significantly at 2 h after incision (P<0.01) and the number of positive cells and protein expression of PKA catalytic subunit in the spinal dorsal horn were increased significantly in control group (P<0.01). Compared with control group, MWT and TWL in pre-incision morphine 2 μg plus clonidine 5 lag group were increased significantly at 2 h after incision (P<0.01) and the number of positive cells and protein expression of PKA catalytic subunit in the spinal dorsal horn were decreased significantly in pre-incision morphine 2 μg plus clonidine 5 μg group (P<0.01). However, MWT, TWL and the number of positive cells and pro-tein expression of PKA catalytic subunit in the spinal dorsal horn changed with no statistical significance in pre-incisional morphine 2.5 μg group and pre-incisional clonidine 5 μg group compared with control group. Conclusion lntrathecal clonidine significantly enhances the antinociceptive effect of intrathecal morphine in a rat model of incisional pain, which might be associated with inhibi-tion of the increased expression of PKA catalytic subunit in spinal cord.
