Summary

The Mason type III and IV radial head fractures are severe injuries that lead to decreased range of motion, alteration in the kinematics, the load transfer and the stability of the elbow. They are often in conjunction with ligament injuries, anterior or posterior joint dislocations and fractures of the coronoid process, the humeral capitulum and the olecranon. The resection of the head leads to elbow instability, late complications and arthrosis of the elbow. The open reduction and internal fixation (ORIF) in Mason type III and IV fractures is not able to restore and sustain the anatomical structure and function of the radiocapitellar joint. That is why these fractures require arthroplasty. The best results are reported with the use of metal bipolar prosthetics. We present our initial experience with radial head arthroplasty on three patients with mean follow up 18 months and a review of the English literature.

tumors, 3 femur tumors and 4 femur and pelvis tumors. 3 out of the total pelvis tumors were treated using custom pelvis reconstruction prosthesis, the other ones using bone graft and standard implants. The femoral tumors were treated using modular prosthesis and bone graft and osteosynthesis implants. Results. Short-term outcome was favorable. Conclusion. Bone defect reconstruction after hip vicinity tumor resection is a technically diffi cult procedure, which requires signifi cant material resources. In terms of quality of life, the results are clearly superior

Abstract

The GCT is an aggressive benign tumor with metastatic potential, most often within the lungs in 2-3% of the patients. It makes about 5% of total bone tumors and about 15% of total benign bone tumors.

The maximum incidence occurs between 30 and 40 years old, most frequently affecting the long bones epiphysis (distal femur, proximal tibia, and distal radius).

We report the case of a 50-year-old female, with no previous medical history, admitted in the emergency department (ED) for significant pain and functional impairment of the left knee. Clinical examination and imaging tests established the diagnosis of distal femoral tumor.

The patient underwent surgical segmental resection of the tumor within oncological limits and subsequent arthroplasty with cemented modular tumoral prosthesis was performed.

Even if the GCT is a benign tumor, it has an aggressive behavior and malignancy potential with an important impact on quality of life. Due to localization, this type of tumor can quickly manifest clinically, which allows an early diagnosis and a less invasive surgical technique.

established the diagnosis of osteosarcoma. Then, we practiced the segmental resection of the tumor, preceded by the embolization of the right femoral artery and after that the reconstruction with bipolar cemented modular prosthesis of the right hip. The patient had a favorable evolution, she did neuromotor rehabilitation, and then she presented to the oncologist for the initiation of adjuvant chemotherapy, which she followed conformably to the recommendations.

use of a modular or customized megaprosthetic implant. Modularity allows versatility for reconstruction and avoids the delay required to make a customized implant. Hypothesis and type of study. Performing a clinical and radiological retrospective study that aims to evaluate long-term efficiency in the use of megaprostheses in segmental distal femur resections. Elaboration of patient selection criteria for modular prosthesis. Materials and methods. We followed retrospectively 33 patients for 5 years from the time of the first surgery. We evaluated the implant

were involved in this study over a period of 4 years (2014-2017) from the Orthopedics and Traumatology Department in the University Emergency Hospital in Bucharest. Tumor resection and reconstruction with modular prosthesis was performed in 4 cases, and tumor resection was necessary in 3 cases and amputation in 4 cases. Pain was evaluated before and after surgery using the Visual Analog Scale (VAS). Early postoperative pain control was achieved with epidural catheter, followed by opioid therapy, NSAIDs and Paracetamol in the early stages of mobilization
