The results of 394 consecutive cases of knee joint radiation synovectomy (radiosynoviorthesis) using Y.

Objective: The aim of this study was to assess the treatment results of Y radiation synovectomy for chronic exudative synovitis of knee joints.

Methods: The retrospective data consist of 394 consecutive knee radiation synovectomies performed using 6 mCi (222 MBq) of Y. The assessment included 3-point custom pain and joint mobility scale, evaluation of joint's circumference, binary joint's temperature evaluation, patellar ballottement test, indications for puncture and its volume in applicable cases.

Manifestations, diagnosis and surgical treatment of enchondroma--own experience.

Background: An enchondroma is a rather common benign tumour of bone that originates from cartilage.The course is usually benign but they have a tendency to recur and are sometimes invasive, especially when developing in long bones. The aim of the study was to analyze the manifestations and methods of treatment as well as to assess the results of surgical treatment in patients with enchondroma.

Surgical treatment of dysplasia fibrosa and defectus fibrosus with bone allografts.

Background: A common feature of dysplasia fibrosa and defectus fibrosus is the development of foci of disordered fibrous tissue in bone that tend to grow and displace regular bone tissue. The objective of this study was to evaluate the efficacy of surgical treatment with bone allografts in patients with fibrous dysplasia and fibrous defect of bone.

Material And Methods: The study group consisted of 99 patients aged from 9 to 58 years (mean age 22 years), including 56 men and 43 women.

Treatment and differential diagnosis of aneurysmal bone cyst based on our own experience.

Background: Aneurysmal bone cyst was first described by Jaffe and Lichtenstein in 1942. Schajowicz in 1972 in his Histopathological Classification of Primary Bone Tumors (later modified by WHO in 1993) placed it in group IX - tumor-like lesions. Its etiology and pathogenesis is not completely clear.

Massive chondroma of pelvis - case report.

The case of a massive pelvis chondroma in a 15-year-old male is described. The patient was previously treated operatively due to multiple chondro-osseous exostoses. An extensive chondrous tumour was detected in the patient's pelvis and abdomen during a follow-up visit.

Treatment methods for neoplastic metastates and tumor-like changes in the bodies and epiphyses of long bones using polymethyl methacrylate cement and bone grafting.

Background. The objective of our study was to evaluate the stabilization of reconstructed long bones after metastatic tumor resection and defect filling with polymethyl methacrylate (PMMA) or bone allograft. Material and methods.

Clinical experience in the application of allogenic grafts from a bone tissue bank in the surgical treatment of tumor-like bone lesions.

Background. The objective of our study was to evaluate the effectiveness of the surgical treatment of bony tumor-like lesions using bone allografts. Material and methods.

Partial long-stem resection Austin-Moore hip endoprosthesis in the treatment of metastases to the proximal femur.

Background. The proximal femur is a frequent location of bone metastases, and pathological fractures in this area are common. A pathological fracture and/or pain associated with bone destruction are indications for surgery.

Evaluation of methods of bone defect reconstruction after iliac tumor resections.

Background. The goal of our research was to evaluate methods of reconstructing iliac bone defects in the authors' own clinical material. Material and methods.

Evaluation of methods of bone defect reconstruction after iliac tumor resections.

Background. The goal of this article is to assess the treatment efficacy of partial shoulder arthroplasty after massive proximal humerus resection following pathological fracture or primary tumor, based on the authors' own clinical material. Material and methods.
