Özet

Aim The aim of this study was to evaluate standardized hip radiographs, arthographs, demographic characteristics, physical examination findings, and their effects on treatment choices in leg-calve-perthes disease (LCPD). Intraobserver and interobserver realibility between orthopaedic residents, orthopaedic surgeons, and paediatric orthopaedic surgeons were also investigated. Materials and Methods 47 LCPD patients were included this cross-sectional study. Six separate presentations including different variabilities (clinical findings, standard radiographs, and arthrographs) were evaluated by three different groups (residents, surgeons, paediatric orthopaedic surgeons) and were sent to the observers every other month by hiding patients' personal information. Seven different treatment modalities were introduced for the best treatment modality. Intraobserver and interobserver reliability in these three groups were examined. Percentage aggreement (PA) and intraclass correlation coefficients (ICC) tests were used for this purpose. Results Treatment PA rates between presentations were 29.5-53.6% in residents, 38.3-60.4% in surgeons, and 39.1-59.8% in pediatric orthopaedic surgeons. Conservative methods were mostly preferred as treatment modality in all groups; followed by proximal femoral osteotomies. Pediatric orthopaedic surgeons preferred safe dislocation and femur head and/or neck reconstruction surgery 5-18 times more than residents and orthopaedic surgeons. Intraobserver reliability of treatment modalities was higher among the paediatric orthopaedic surgeons; the results were fair-good (0.483-0.763). Among residents and orthopaedic surgeons, ICC values were poor to good, respectively (- 0.080 to 0.636 and 0.263-0.643). Interobserver reliability among three groups was meanly good. Conclusion As surgical experience increases, both the compliance rates of the treatment modalities and the intra- and inter-group reliability are increased. Knowledge of the demographic data and clinical findings of patients besides hip radiographs or arthrographs increase treatment compliance in paediatric orthopaedic surgeons, however, cause changes in treatment modalities in residents. As surgical experience increases, more difficult surgeries such as safe dislocation and femoral head/neck reconstruction are preferred.
