Abstract


Objective — to study the role of instrumental methods in the diagnosis of complications after hip arthroplasty.
Material and Methods. Using the methods of computed tomography, bone scintigraphy, radiography and thermography, we have examined 42 patients after hip arthroplasty (26 women and 16 men) aged 54 to 75 years. Bacteriological examination of the tissues surrounding the prosthesis and prosthetic material revealed postoperative infection.
Results. In 27 (64 %) patients according to radiography, in 31 (75 %) — according to computed tomography, in 36 (86 %) — according to bone scintigraphy and in 38 (90 %) patients according to thermography, we have revealed signs characteristic of postoperative complications in hip arthroplasty. Computed tomography and radiography in patients, who were examined, revealed more precise contours of the lesion than bone scintigraphy and thermography, as well as more qualitatively determined the localization of pathological process among anatomical bone structures. During bone scintigraphy and thermography, pathological changes in the projection of the hip joints were visualized earlier than in computed tomography and radiography.
Conclusion. Computed tomography and radiography are more specific methods than bone scintigraphy and thermography, but less sensitive in the diagnosis of acute postoperative complications in hip arthroplasty. These methods can be used in the diagnostic screening of acute postoperative complications with hip arthroplasty. When diagnosing pathological conditions in hip arthroplasty, simultaneous classic radiography and bone scintigraphy should be used, and in combination with computed tomography — to monitor the dynamics of the pathological process after hip arthroplasty.
