[The tolerance of the hip prosthesis evaluted through scintigraphic studies (author's transl)].

The authors assert the usefulness of the scintigraphy in the early diagnosis and/or for the confirmation of the main complications connected with the artroprosthesis of the hip. Such investigation is effective only if it is carried out at a distance of at least six months from the operation and must be completed by clinical, bio-humoral and radiographic tests. This study is based on the observation of 40 cases, of which 20 represent the control group. The isotope used is the Tc99m-pyrophosphate.

Patellofemoral malalignment in adolescents. Computerized tomographic assessment with or without quadriceps contraction.

Twenty-seven adolescents with anterior knee pain with or without patellar instability were studied by computerized tomography to detect patellofemoral malalignment. The examination was performed with and without quadriceps contraction with the knee flexed to 15 degrees. Congruence angle, patellar tilt angle, sulcus angle, and trochlear depth were measured. This investigation showed the well-known types of patellofemoral malalignment with quadriceps relaxed (tilted, lateralized, lateralized, and titled patella) and, in 52% of cases, revealed changes in type and severity with quadriceps contraction (in 41%, lateralization and tilting were markedly more evident; in 11%, the type of malalignment changed). The results demonstrate that, in addition to assessment with quadriceps relaxed, computerized tomography with quadriceps contraction is a useful adjunct to diagnose and define the type of malalignment in particularly difficult circumstances.

Slipped capital femoral epiphysis: comparison of a roentgenographic method and computed tomography in determining slip severity.

Various conventional roentgenographic methods have been proposed to determine the severity of chronic slipped capital femoral epiphysis (SCFE) on the sagittal plane, with some maintaining that computed tomography (CT) is more accurate and reproduces better than roentgenography. We used a modified Dunlap's technique and angular measurement to determine slip severity. Three orthopaedists obtained data from roentgenograms and CT of 20 hips with chronic SCFE. Statistical analysis showed concordance between our method and the measurements and reproducibility produced with CT. The results suggest that our method is as effective as and less expensive than CT.
