A rare benign bone condition called monostotic fibrous dysplasia (MFD) is characterized by the growth of fibrous tissue in place of a normal bone. It may lead to deformity in the affected bone, pain, and a pathologic fracture due to bone weakness. Hereunder, a case report of MFD in a 17-year-old male adolescent presenting to the hospital with localized bone pain and swelling in his right tibia is presented. After clinical examination and radiographic imaging, a provisional diagnosis of benign osteolytic lesion was considered. A magnetic resonance imaging (MRI) scan of the leg suggested the possibility of fibrous dysplasia or adamantinoma. The patient was managed with an intralesional curettage of the dysplastic bone and packing the cavity with blocks of a synthetic bone. The excised material was sent for histopathology, which established the diagnosis of fibrous dysplasia.

Paediatric distal tibial and fibular fractures are seen quite regularly in orthopaedic trauma practice. Most patients are managed conservatively with closed reduction or casting while only a selected few required surgical treatment. Surgical options include plating, percutaneous Kirschner wires, rigid intramedullary nails, and flexible intramedullary nailing. This is dependent upon the patient\'s age, fracture site, comminution, and concomitant injuries. Here, we present an interesting case of a patient with an unusual lesion seen at the fracture site. This lesion was curetted out during surgery and filled with an injectable synthetic Cerament bone void filler (Bone Support AB, Lund, Sweden), which later formed into bone and allowed the bone to remodel.

With the aim of achieving an optimal aesthetic result, implant dentistry has become a prosthetically driven procedure. Special care is being taken to focus on the details that would lead to this objective. These details may include imitating the natural teeth by harmonizing the structures around the placed implant. The prosthetic and/or surgical parts of the procedure should be performed to reach an optimal outcome. In order to minimize the resorption of hard and soft tissue, which exists around the newly extracted tooth-to create a natural emergence profile of implant born prosthesis-socket preservation procedures were introduced; however, in case of ridge deficiencies, hard and soft tissue augmentation procedures are indicated. In this article, we present a case report using a new approach in socket ridge preservation, which is the socket-shield technique (partial root retention).

Managing infections of the first metatarsophalangeal joint can be demanding because many patients present with late-stage infection and partial or total amputation of the first ray or the phalanx could be necessary. We describe such a patient who was successfully treated with a calcium-based resorbable bone substitute that preserved the first metatarsophalangeal joint. A 38-year-old female presented to our department with a foot infection. Examination revealed a methicillin-susceptible Staphylococcus aureus infection of the first metatarsophalangeal joint. The histopathologic findings confirmed active osteomyelitis of the first metatarsal head. The metatarsophalangeal joint was debrided with open synovectomy, the metatarsal head was curetted, and the bone defect was filled with 2 mL of a synthetic bone graft substitute. Two years later, she reported no problems with function or pain, the joint had full range of motion, and she had no local or systemic signs of infection. The most recent radiographs revealed no damage to the first metatarsophalangeal joint. A synthetic bone graft substitute can be a good alternative for treating forefoot infections when the soft tissues are intact and the bone defect is not so large that partial or full amputation is necessary.

BACKGROUND: Avascular necrosis (AVN) of the femoral or humeral heads in patients with sickle cell anemia is a common and painful condition. There is currently no gold standard treatment protocol for this condition. Typically, the pain is managed with narcotics and activity restriction until there has been collapse of the subchondral bone with a degree of arthrosis sufficient to warrant total joint arthroplasty. This method entails prolonged pain for the patient and decreases the ability to function occupationally and recreationally.
METHODS: A 51-year-old African-American woman with a history of sickle cell anemia presented for the evaluation of significant bilateral shoulder pain that was confirmed to be AVN via radiographs and magnetic resonance imaging of both her humeral heads without joint collapse. She tried and failed conservative management with physical therapy and optimization of sickle cell treatment with pain medications for years, so she desired surgical management. Arthroscopically assisted core decompression of her humeral heads with synthetic grafting was performed in an attempt at joint preservation.
CONCLUSIONS: This report demonstrates a technique of staged decompression of necrotic bone in the bilateral humeral heads with synthetic bone grafting to determine if this could function as a joint preservation strategy. This procedure was considered successful to alleviate the patients\' pain in both of her arms. The application of this procedure is significant because it could be used in various future medical joint preservation cases for a wide range of patients.
