To investigate incorporation of the grafted bone used for acetabular reconstruction.
Single photon emission computed tomography (SPECT) was carried out at the 1st, 6th, and 12th month after the operation and the uptakes on serial SPECT scintigrams were normalized. The horizontal histogram of scintigraphic activity at the level of the central grafted bone in the coronal image was designated the profile curve.
Seven patients who had undergone bipolar hip arthroplasty for osteoarthritis of the hip were randomly selected.
Five of seven profile curves obtained at the 1st month demonstrated a single peak at the host-graft junction. The profile curve obtained at the 6th month showed two peaks at the host-graft junction and the periphery of the grafted bone in all patients. The profile curve at the 12th month showed slightly increased activity in the center of the grafted bone. This preliminary study demonstrates that comparison of the serial profile curves on SPECT is valuable in evaluating the progress of incorporation of the grafted bone in hip arthroplasty.
研究用于髋臼重建的移植骨的融合情况。
在术后第1、6和12个月进行单光子发射计算机断层扫描(SPECT),并对系列SPECT闪烁图上的摄取情况进行标准化。将冠状位图像中移植骨中心水平的闪烁活性水平直方图指定为轮廓曲线。
随机选择7例因髋关节骨关节炎接受双极髋关节置换术的患者。
第1个月获得的7条轮廓曲线中有5条在宿主-移植骨交界处显示单个峰值。第6个月获得的轮廓曲线在所有患者的宿主-移植骨交界处和移植骨周边均显示两个峰值。第12个月的轮廓曲线显示移植骨中心的活性略有增加。这项初步研究表明,比较SPECT上的系列轮廓曲线对于评估髋关节置换术中移植骨的融合进展具有重要价值。
