RESUMEN
Giant cell tumors (GCTs) of the bone are uncommon neoplasms that predominantly affect the metaphysis of long bones, with proximal humerus involvement being less frequent. We present the case of a 58-year-old male who presented with a two-month history of progressive right shoulder pain and difficulty in raising his arm. Clinical examination revealed a palpable swelling on the lateral aspect of the right arm. Radiological investigations, including X-ray and magnetic resonance imaging (MRI), confirmed the presence of a primary osseous neoplasm involving the proximal humerus, suggestive of a GCT. The patient underwent surgical excision of the tumor with bone grafting and bone cementing of the proximal humerus. Post-operative care included prescribed medications and physiotherapy. This case highlights the successful management of GCTs of the proximal humerus through a multidisciplinary approach, emphasizing the importance of meticulous surgical technique, appropriate reconstruction, and comprehensive post-operative care for optimal patient outcomes.
RESUMEN
Giant cell tumors (GCTs) of the bone present unique challenges in management due to their locally aggressive nature and potential for recurrence. This case report describes the successful surgical management of a GCT located in the proximal tibia of a 28-year-old female. The patient presented with six months of pain and swelling following a traumatic injury to the knee. Diagnostic imaging confirmed the presence of a GCT, leading to preoperative prophylactic embolization to reduce intraoperative bleeding. Surgical excision of the tumor was performed, followed by reconstruction using autologous fibula grafts and plate fixation. Postoperative care included analgesia, antibiotics, and physiotherapy. Regular follow-up demonstrated satisfactory clinical outcomes without evidence of recurrence. This case highlights the importance of a multidisciplinary approach combining surgical expertise, preoperative planning, and postoperative rehabilitation to achieve favorable outcomes in managing GCTs.
RESUMEN
This comprehensive review delves into the emerging role of platelet-rich plasma (PRP) in accelerating bone healing. PRP, a blood-derived product rich in platelets and growth factors, has garnered attention for its regenerative potential. The review begins by defining PRP and providing a historical background, highlighting its significance in expediting bone healing. PRP's composition and preparation methods, including centrifugation techniques and commercial kits, are explored. Mechanistically, PRP operates by releasing growth factors, chemotaxis, and angiogenesis, elucidating its cellular effects. Applications in fracture healing and orthopaedic surgeries, such as joint arthroplasty and spinal fusion, are discussed, emphasising the promising outcomes in clinical trials. Safety considerations, patient selection criteria, and the need for PRP preparation and application standardisation are underscored. The review outlines ongoing research trends, potential technological advancements, and unexplored areas in paediatric applications and inflammatory bone disorders. The implications for clinical practice involve informed decision-making, optimised protocols, and interdisciplinary collaboration. In conclusion, the future of PRP in bone healing holds exciting prospects, with the potential for precision medicine, integration with emerging therapies, expanded applications, and enhanced technological innovations shaping its trajectory in orthopaedics and regenerative medicine.
