Introduction. Chondrosarcoma is a malignant tumor of cartilaginous origin representing approximately 20-30% of all bone malignant tumors and occupying the second place in terms of their incidence. It usually affects adults between 40 and 60 years old, but can be encountered at older ages as well. Materials and methods. We report the case of a 55-year-old male patient who presented to our department with 2 weeks-long right hip pain and partial loss of functionality in right limb. We performed X-rays, magnetic resonance imaging, computed tomography, bone scintigraphy, and angiography, which established the diagnosis of pelvic tumor. Biopsy of the tumor was performed by iliofemoral approach and its result showed moderately differentiated chondrosarcoma. Orthopaedic surgery was performed, with tumoral removal within oncological limits, pelvic reconstruction using acrylic bone cement impregnated with Vancomycin and total hip arthroplasty. Results were assessed using the Musculoskeletal Tumor Rating Scale and a score of 23 out of 35 was obtained (the higher the better). Postoperative complications consisted in flap-skin necrosis that resolved within 2 months after surgery. Conclusion. Bone defects repair using antibiotic impregnated cement drastically reduced the rate of postoperative infections, thus decreasing both morbidity and mortality. In spite of technological advancement, long-term prognosis remains reserved in chondrosarcoma, due to its specific aggressivity, resistance to chemo-and radiotherapy and high rate of recurrence.
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.
Aim: To assess the clinical results after osteosynthesis with locked intramedullary nail in metastasis of the long bones. Material and methods. We designed a prospective study in which we included all the patients with metastasis of the long bones admitted and surgically treated in our department between 2013 and 2015. Data for 64 were available at the final check-up. Our cohort totalized a number of 69 fractures (2 long bones required surgical treatment in 5 patients). The mean follow-up for survivors was 37 months (limits: 18-49 months). The primary tumor was known in 51 patients (79,69%). For the remaining 13 cases (20,31%), the primary tumor was not known and the pathological fracture was the first sign of the malignant disease. In the last group, the tumor could be identified by imagistic methods in 6 cases, while in other 3 cases, a biopsy and histological examination (which were performed in all the remaining 7 cases) determined the source organ. Clinical and radiological check-ups were performed at every 3 months in the first year and at every 6 months after that. Results. Pain amelioration and mobilization of the involved limb were achieved in all the cases. In 3 patients, the osteosynthesis could not compensate the progressive bone loss and the permanent use of an external orthosis was mandatory. The survival rate was 82,81% at 6 months and 67,19% at 12 months. Conclusions. All patients could be mobilized. Two thirds of the patients will survive more than a year. The goals of osteosynthesis are the same, regardless the location of the fracture and implant used: pain amelioration, stability for immediate full weight bearing, durability for patient’s life expectancy.
Periprosthetic joint infection is the most common reason for a failed TKA, with a septic TKA reported rate of 1 to 4% of primary TKA patients. Septic TKA has a various number of treatment options which include chronic-suppressive antibiotics, irrigation and debridement, single or staged revision arthroplasty. The goal is to eradicate the periprosthetic joint infection and reimplant a sterile and fully functional total knee prosthesis. In case the infection becomes uncontrollable, there is only one option to eradicate the infection: knee arthrodesis or above-knee amputation.We report the case of a 63-year-old patient who in 2009 underwent TKA, the 1 year follow-up showed periprosthetic infection. At first stage, the prosthetic implants were removed and a solid cement spacer was shaped to occupy the remaining space. In 2011, after achieving complete clinical and biological remission of the infection, the cement spacer was removed and LCCK revision prosthesis was inserted.In 2013 reinfection occurred leading to removal of the prosthetic implants and reinsertion of an antibiotic impregnated cement spacer.Since the patient suffered significant bone loss and the local conditions were unfavorable, being prone to infection, there were 2 options to evaluate: knee arthrodesis or above knee amputation. We chose knee arthrodesis using Ilizarov external fixation technique.Many surgical techniques are available to achieve knee arthrodesis: internal fixation with plates or intramedullary nails and external fixation. The Ilizarov method is a very effective technique that could be taken into consideration when knee arthrodesis is required.
Introduction: The aim of the study was to report the clinical and functional outcomes in patients undergoing limb salvage with various reconstruction techniques in primary malignant bone tumor.Materials and methods: This study was performed between 2011 and 2018 on 52 patients with primary malignant bone tumors admitted to the Department of Orthopaedics and Traumatology of University Emergency Hospital, Bucharest. All the patients underwent surgical treatment (resection-reconstruction technique) followed by oncologic therapy. The mean follow-up was 3 years and 8 months and the minimum follow-up was 12 months.Results: The best results were obtained in patients in whom resection of the tumor followed by reconstruction was possible, without affecting the adjacent joint through arthrodesis or arthroplasty. These patients had an average MSTS score of 75.2%. The patients who underwent reconstruction procedures by endoprosthesis also had good results with an average MSTS score of 72.3%, while patients with arthrodesis obtained rather modest results – the average MSTS score being 67.3%. When taking into consideration the location of tumors, the best MSTS scores were obtained in patients with tumors of the distal radius – 80%, followed by femoral and humeral diaphysis – 75.6%, distal femur – 75.2%, proximal femur – 73.3%, proximal humerus – 72.3%, tibial diaphysis – 72.2%, distal tibia – 70% and proximal tibia 68.7%.Conclusions: The orthopedist must judiciously chose the surgical technique, taking into consideration the anatomical particularities and the needs of the patient. Given the functional results and the emotional acceptability, reconstruction with tumor prosthesis represents the first option.
