Infection in orthopaedic and trauma surgery remains a destructive complication with particularly challenging diagnosis and treatment due to bacterial antibiotic resistance and biofilm formation. Along with surgical debridement and systemic antibiotics, an important type of adjuvant therapy is local antibiotic delivery, with the purpose of eliminating bacterial colonization and biofilm development. Calcium sulphate, as a synthetic absorbable biomaterial used for local antibiotic delivery, has experienced an increasing popularity during the last decade, with multiple promoted advantages such as predictable antibiotic elution kinetics, complete and quick biodegradation, good biocompatibility, and limited associated complications. A series of commercially available antibiotic-delivery systems based on calcium sulphate are under investigation and in clinical use, with different presentations, compositions, and application techniques. The current article presents the main available calcium-sulphate-based products and the existing data about the clinical and preclinical research results, stemming from their implementation as local antibiotic carriers for surgical site and implant-associated infections treatment and prevention.

Bone metastases are difficult to treat surgically, necessitating a multidisciplinary approach that must be applied to each patient depending on the specifics of their case. The main indications for surgical treatment are a lack of response to chemotherapy, radiation therapy, hormone therapy, immunotherapy, and bisphosphonates which is defined by persistent pain or tumor progression; the risk of imminent pathological bone fracture; and surgical treatment for single bone metastases. An important aspect of choosing the right treatment for these patients is accurately estimating life expectancy. Improved chemotherapy, postoperative radiation therapy, and sustainable reconstructive modalities will increase the patient’s life expectancy. The surgeon should select the best surgical strategy based on the primary tumor and its characteristics, the presence of single or multiple metastases, age, anatomical location, and the functional resources of the patient. Preventive osteosynthesis, osteosynthesis to stabilize a fracture, resections, and reconstructions are the main surgical options for bone metastases. Resection and reconstruction with a modular prosthesis remain the generally approved surgical option to restore functionality, increase the quality of life, and increase life expectancy. Preoperative embolization is necessary, especially in the case of metastases of renal or thyroid origin. This procedure is extremely important to avoid complications, with a major impact on survival rates.
Gonarthrosis is one of the main causes of pain and limitation of physical activity in elderly patients. The diagnosis is established based on the clinical and radiological examination, and the treatment consists of non-surgical measures. The final stage of gonarthrosis is treated surgically and consists of total knee arthroplasty. The molecular study in gonarthrosis aims to identify patients with early stages of arthrosis, with reversible potential, who can benefit from etiological treatment and non-pharmacological measures to slow down the evolution of the disease or even reversibility. Total knee arthroplasty is a surgical intervention with the role of reducing the symptoms and restoring the functionality of the affected joint. Total knee arthroplasty remains the surgical intervention of choice in the case of patients in the final stage of the evolution of the disease with very good functional outcome.
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.
