< Back Hand & Fingers Injuries to the hand and fingers are common and vary from simple lacerations and fractures to complex tendon and joint injuries. Accurate diagnosis and timely management are crucial to preserve function. Hand and finger trauma encompasses a wide spectrum, including phalangeal fractures, dislocations, tendon lacerations (flexor/extensor), and nail bed injuries. Mechanisms include crush injuries, direct blows, and lacerations. Initial assessment includes inspection for deformity, neurovascular status, range of motion, and tendon function. Radiographs are essential to evaluate fractures or joint dislocations. Common injuries: Mallet finger Jersey finger Boutonnière and swan-neck deformities Metacarpal neck (Boxer’s) fracture Open fractures (risk of infection) Treatment varies: from splinting and buddy taping to surgical fixation or tendon repair. Rehabilitation and early motion are vital to prevent stiffness. hand-fingers Previous Next

< Back Anticoagulants Anticoagulants are medications that prevent clot formation. They are essential in orthopaedics for thromboprophylaxis, especially after surgery. Common Anticoagulants in Orthopaedics: Low Molecular Weight Heparin (LMWH): Enoxaparin Direct Oral Anticoagulants (DOACs): Rivaroxaban, Apixaban, Dabigatran Unfractionated Heparin Warfarin (less common due to monitoring needs) Indications in Orthopaedics: Prevention of deep vein thrombosis (DVT) and pulmonary embolism (PE) after joint replacement or major trauma Management of patients with a history of thromboembolism Atrial fibrillation with orthopaedic comorbidities Key Considerations: Start prophylaxis 6–12 hours after surgery (depending on bleeding risk) Continue for at least 10–14 days, sometimes up to 35 days in hip replacement Adjust dosing for renal function Monitor for signs of bleeding (wound hematoma, prolonged bleeding) Contraindications: Active bleeding Severe bleeding risk (e.g., recent CNS surgery) Coagulopathy Bridging and Reversal: Reversal agents: Protamine (heparin), Vitamin K (warfarin), Idarucizumab (dabigatran) Bridging required with LMWH in warfarin patients undergoing surgery Previous Next

< Back Dr. Serkan BAYRAM Endoprosthesis Endoprosthetic reconstruction is a cornerstone technique in musculoskeletal oncology, allowing immediate restoration of skeletal continuity and early mobilization after wide tumor resection. Modern modular megaprostheses, made of titanium or cobalt-chromium alloys, are designed for durability, functional recovery, and ease of revision. They are primarily indicated for periarticular or diaphyseal bone loss following tumor excision, failed fixation, or pathological fractures. Cemented fixation ensures immediate stability, while press-fit and porous-coated designs promote biological integration. Despite excellent limb salvage rates (>90%), complications such as infection, aseptic loosening, and mechanical failure remain challenges. Advances including silver-coated implants, expandable pediatric prostheses, and improved soft-tissue reattachment techniques continue to enhance long-term outcomes and quality of life for oncology patients. Definition An endoprosthesis is a modular metallic implant used to reconstruct bone and joint defects following wide resection of primary or metastatic musculoskeletal tumors. The aim is to achieve immediate structural stability , preserve limb function, and allow early mobilization, particularly in cases where biological reconstruction (allograft or autograft) is not feasible. Indications Segmental bone loss after tumor resection, particularly in the proximal humerus , distal femur , and proximal tibia . Periarticular destruction due to primary bone sarcomas (e.g., osteosarcoma, Ewing sarcoma) or metastatic disease. Reconstruction after pathological fractures or failed fixation in oncologic bone. Salvage after infection or mechanical failure of previous reconstruction. Design and Components Modern tumor prostheses are modular megaprostheses made from titanium or cobalt-chromium alloys, often with: Cemented or press-fit stems for fixation into the remaining diaphysis. Rotating hinge joints (knee and elbow) to reduce torque and wear. Porous-coated or hydroxyapatite collars to promote soft-tissue and bone integration. Expandable designs for skeletally immature patients, allowing non-invasive limb-length adjustment. Cemented fixation offers immediate stability, while cementless (press-fit) fixation supports long-term biological fixation and easier revision. Surgical Principles Wide oncologic margins are mandatory to minimize local recurrence. Preservation of neurovascular structures and soft-tissue coverage is essential. Stable fixation and restoration of limb length should be achieved intraoperatively. Reconstruction of muscle attachments (especially in proximal humerus and tibia) improves functional outcome. Prophylactic antibiotic cement or silver-coated implants are used to reduce infection risk in high-risk cases. Advantages Immediate load-bearing capability. Shorter operative time compared to biological reconstructions. Predictable early function and pain relief. Can be revised modularly if components wear or fracture. Complications Infection (5–15%); more common in immunocompromised or irradiated patients. Mechanical failure (loosening, stem breakage). Aseptic loosening due to stress shielding. Periprosthetic fracture and soft-tissue failure (e.g., extensor mechanism insufficiency). Outcomes and Prognosis Endoprosthetic reconstructions provide excellent pain relief and limb salvage rates exceeding 90% in modern series. Five-year implant survival is around 70–80% , depending on site and indication. Long-term durability is enhanced by improved modular designs, better fixation strategies, and multidisciplinary care.
