Abstract


The affection of the proximal femur with malignant tumors ranked first in the case of metastatic lesions and the second - among all sites of primary malignant tumors of the long bones. Anatomically, this area is quite sophisticated and high accuracy of topical diagnosis and evaluation of tumors prevalence is required. Spiral computed tomography (SCT) provides an accurate representation of tumors spread to bone and surrounding soft tissues. The problems of development patterns of extra-osteal component of tumor in upper third of the arm, soft tissue reconstruction, restoration of joint function and limb as a whole.

The goal: to investigate the features of lesions of bone and soft tissue structures in malignant tumors of the upper third of the thigh based SCT data.

The methods: the results of SCT studies of 55 patients with lesions of the upper third of the femur with malignant tumors were selected for analysis. SCT results were analyzed according to the method that was designed to assess the prevalence of tumor process in the proximal femur. The method is based on the study of tumor growth along the thigh, the direction and extent of the tumor extra-osteal component in the horizontal plane.

The results: a working classification of tumor dissemination in the proximal femur, depending on the extension of the tumor along a portion of the upper half of the thigh, the development direction and severity of tumor process in soft tissues is proposed.

Conclusion: the proposed working classification will help to determine the possibility of surgical treatment of patients with malignant tumors of the upper third of femur, as well as to clarify the indications for different types of organ-saving surgical treatment of with soft tissue reconstructive procedures for femur and hip to improve functional outcomes of patient treatment.
