Giant cell tumor (GCT) merupakan tumor destruktif tulang yang muncul di antara dekade kedua dan keempat, lokasi predileksi umumnya pada epifisis tulang panjang. Pemilihan tatalaksana operasi sangat penting dan masih menjadi perdebatan. Sebagaimana masih beragamnya pilihan tindakan pembedahan. Klasifikasi Campanacci dapat digunakan sebagai acuan untuk panduan tatalaksana. Pada kasus ini kami melaporkan seorang wanita, usia 18 tahun dengan diagnosa giant cell tumor pada proximal tibia dextra dengan Campanacci grade III. Pasien telah menjalani operasi limb salvage tahap pertama berupa eksisi luas pada proximal tibia dextra dan knee arthrodesis. Setelah 4 bulan dilakukan operasi limb salvage tahap kedua yaitu knee arthroplasty dengan megaprosthesis. Untuk mencegah komplikasi implant expose, dilakukan muscular flap dan split thickness skin grafting (STSG). Setelah dilakukan evaluasi selama 4 bulan, klinis pasien baik, pasien dapat berjalan alat bantu dan tanpa nyeri, tidak ada komplikasi pada luka operasi dan fiksasi implan baik. Kesimpulan yang didapatkan bahwa limb salvage surgery pada giant cell tumor proximal tibia dapat dilakukan dengan tindakan rekonstruksi dua tahap. Teknik muscular flap dan split thickness skin grafting (STSG) dapat digunakan untuk mencegah terjadinya implant expose.
<p>The incidence of femoral neck fractures in pediatric patients is rare, including <1% in all cases of fractures in children. The mechanism of injury is a high-energy injury that can cause a fracture in the femoral neck, open fracture cases are rare. Avascular necrosis is the most common complication. We report a fourteen year old boy who was in a road-traffic accident and had a Gustillo Anderson grade IIIA open femoral neck fracture. On the X-ray findings, we classified the type of fracture into Delbet type II. We decided to do the debridement and ORIF accompanied by an osteomuscular pedicle graft using a quadratus femoris muscle tendon fixed with 3 interfragmentary screws. Short-term evaluation shows a clinical union picture and is still well reduced without any signs of infection. Long-term evaluation of the bone healing process is needed and recognizes complications in the form of avascular necrosis of the femoral head.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
