[Use of Solid Intercalary Allografts for Reconstruction Following the Resection of Primary Bone Tumors].

PURPOSE OF THE STUDY There are several treatment options for bone tumors at diaphyseal/metadiaphyseal sites of long bones (with joint preservation) including massive intercalary allografts, autografts (vascularized or non-vascularized fibular autograft, devitalised tumor bearing bone), endoprosthetic replacement (intercalary spacer), cementoplasty with ostheosynthesis and distraction osteogenesis. Reconstruction using massive intercalary bone allografts is for us the method of choice in case of curable primary bone tumors at the diaphyseal/metadiaphyseal region. The purpose of this study is to evaluate our results and complications.

[Analysis of prognostic factors in osteosarcoma adult patients, a single institution experience].

Background: The objective of this report was to estimate long-term outcome and prognostic factors in adult patients with high-grade osteosarcoma. The intended therapeutic strategy included preoperative and/or postoperative chemotherapy as well as surgery of all operable lesions.

Patients And Methods: We reviewed the clinical data of 36 newly diagnosed adult patients (aged 19-82, average 37.

Use of the harmonic system in total hip arthroplasty: a prospective, comparative, observational study.

We compared technical issues, postoperative outcomes and surgical complications of total hip arthroplasty when using the harmonic scalpel (HS) when compared with conventional techniques (CT) in a prospective, comparative observational study. Thirty patients undergoing total hip arthroplasty were assessed. Operative time, blood loss in drains, postoperative pain, soft tissue injury and complications were recorded.

The arthroscopic debridement in the management of osteoarthritis of the knee joint by high tibial osteotomy.

The Aim Of The Study: The authors evaluated the benefits of the arthroscopic debridement performed in the same session with the high tibial osteotomy in the management of the knee joint of osteoarthritis connected with varus or valgus deformity.

Material And Methods: Arthroscopy was indicated in 52 patients from 96 patients with high tibial osteotomy in the years 1996-2001.

Results: Significant intraarticular disorders were found in all 52 patients.

[Primary bone hyperparathyroidism].

The authors report the case of a 19-year-old girl with osteolytic bone lesions in whom primary hyperparathyreoidism caused by parathyroid gland adenoma was diagnosed. They emphasize necessity to be aware of a relationship of this rare condition to bone lesions that may be benign in appearance and may show ambiguous histological findings. The patient underwent excision of the adenoma and subsequent substitution therapy, which resulted in the healing of bone lesions.
