Objective The aim of this study was to retrospectively evaluate the patients who were operated in our orthopedics and traumatology clinic with the suspection of bone and soft tissue tumors. Methods A total of 3133 patients (1146 (46.5%) female and 1318 (53.5%) male) who presented to our tertiary clinic from different regions of Turkey between January 2002 and July 2013 with the presumed diagnosis of bone and soft tissue tumors were analyzed according to age, gender, bone/soft tissue localization, tumoral localization, histopathological diagnosis, tumor size and incidence. Results Of all operated patients, 2464 (78%) were diagnosed with tumor, while non-tumoral causes were found in 669 (22%) patients. Of the cases diagnosed with tumor, 1139 were bone localized, 1004 soft tissue localized, and 321 metastasis. The most common benign bone tumors were osteochondroma (130, 20%), enchondroma (96, 15%), and simple bone cysts (90, 14%), while the most common malignant bone tumors were osteosarcoma (241, 44%), ewing's sarcoma (89, 16%), and chondrosarcoma (77, 14%); respectively. The most common benign soft tissue tumors were lipoma (141, 22%), giant cell tumors (108, 16%) and ganglion (107, 16%), while the most common malignant soft tissue tumors were liposarcoma (55, 16%), synovial sarcoma (53, 16%) and malignant mesenchymal tumors (45, 13%); respectively. Conclusion Musculoskeletal tumors are rare, but descriptive data in any region are important in order to reduce mortality and improve treatment. No significant difference was found between the data of our hospital regarding epidemiology of the musculoskeletal system tumors and those from the other regions around the world. Level of evidence Level IV, Therapeutic study.
Although challenges in treatment of musculoskeletal hydatid cysts (HC) lesions have been documented, data regarding the musculoskeletal HC lesions resembling tumor is scarce. This paper presented 5 patients (3 males, 2 females) with a mean age of 41.6 years with tumor-like lesions of HC. Three of them had left ilium and acetabulum involvement, one involved left femur, and one involved left thigh muscle compartments. Pain was the main symptom and was seen in all patients. Clinical examination, radiologic evaluation, and histologic analysis were performed for diagnosis. Patients were treated through different surgical options, including simple debridement, bone cement filling with or without internal fixation, hip arthrodesis, reconstruction using hemipelvic replantation with femoral prosthesis and distal femur endoprosthetic replacement. After surgery, the operation region was washed by 20% hypertonic saline, and debridement was performed carefully without contamination. All patients received albendazole treatment. Cases were followed up 1 to 9 years for the recurrence. Walking difficulty and pain were the main symptoms during the follow-up. One patient was symptom-free. A reoccurrence in the perioperative soft tissue was detected in only one patient and control visits with antihelmintic treatment were recommended. We would like to emphasize that HC should be kept in mind for the differential diagnosis of the cystic or tumoral lesions of the musculoskeletal system, particularly in the endemic regions. Prompt diagnosis is of paramount importance for preventing destruction and complications.
This study aims to investigate the effects of hyperbaric oxygen (HBO) therapy and platelet-rich plasma (PRP) on the regeneration of osteochondral defects of the rats, and the synergistic effect of this combined treatment. Materials and methods: This randomized, controlled, and interventional animal study was conducted between May 2014 and August 2014 Osteochondral regeneration was evaluated in four treatment groups (control, PRP, HBO, and HBO+PRP groups) at the 30 th day after iatrogenic injury. Thirty-two female Wistar albino rats (weighing 248-305 g) underwent arthrotomy and osteochondral surgery on left knees. The regenerations of defects were then examined histologically by the modified version of O'Driscoll score. Results: Groups that were treated with either HBO or PRP alone regenerated significantly better than the control group (p=0.01), while no significant difference was found between the HBO-and PRP-treated groups (p>0.05). The defects in group 4 (treated with both HBO and PRP) regenerated significantly better than the control group, the HBO-treated group alone, and the PRP-treated group alone (p=0.01). Conclusion: The results of this study showed a synergistic effect of HBO and PRP on knee cartilage regeneration. However, the possible underlying mechanisms should be the subject of future researches. The aggregation and activation of growth factors released from platelets whose activation is increased in the hyperbaric environment may explain this effect. This may result in a better regeneration than the effect of PRP or HBO alone.
Nora'nın lezyonu olarak da bilinen bizarre parosteal osteokondromatöz proliferasyon, kemikten egzofitik büyüme ile kendini gösteren, benign bir lezyondur. Bu çalışmada, 2010-2018 yılları arasında tedavi edilen Nora lezyonuna sahip dört hastanın değerlendirilmesi ve kısa bir literatür taraması yapılarak güncel bilgilerin incelenmesi amaçlandı. YÖNTEM ve GEREÇLER: Ortalama yaşları 32+24 std (26-37 yaş arası) olan iki erkek ve iki kadın toplam 4 hasta çalışmaya dahil edildi. Hastaların tanıya kadar geçen süre ve semptomları, klinik bulguları, kitle boyutu, MRI bulguları, cerrahi tedavileri, tedavi sonuçları ve komplikasyonlar incelendi. BULGULAR: Tüm hastalara marginal eksizyon yapıldı. En sık kitle lokalizasyonu ön kolun uzun kemikleri idi. Bir vakada post-operatif 24. ayda rekürrens görüldü, nüks rezeksiyonu yapıldı. Diğer üç hastada takiplerinde nüks ya da komplikasyon görülmedi. TARTIŞMA ve SONUÇ: Bizarre parosteal osteokondromatöz proliferasyon, vücudun birçok farklı lokalizasyonunda yerleşebilen, benign karaktere sahip ancak sık rekürrens ile karşımıza çıkabilen, nadir bir kemik lezyonudur. İyi bir preoperatif planlama ile yapılan dikkatli bir marginal eksizyon, nüksün önlenmesinde en önemli anahtardır.
