Partial Two-Stage Exchange for Infected Total Hip Arthroplasty: A Treatment to Take into Account.

Introduction: Two-stage revision is the gold standard for chronic periprosthetic joint infection (PJI). The removal of well-fixed implants, especially the femoral component, can be extremely difficult and additional osteotomies may be needed, which is time-consuming and results in bone stock loss. When the femoral stem is osseointegrated, there is no clear indication for the use of partial two-stage revision.

Towards the Search for Potential Biomarkers in Osteosarcoma: State-of-the-Art and Translational Expectations.

Osteosarcoma represents a rare cause of cancer in the general population, accounting for <1% of malignant neoplasms globally. Nonetheless, it represents the main cause of malignant bone neoplasm in children, adolescents and young adults under 20 years of age. It also presents another peak of incidence in people over 50 years of age and is associated with rheumatic diseases.

Bone impaction grafting with trabecular metal augments in large defects in young patients: unravelling a new perspective in surgical technique.

Background: Acetabular reconstruction with bone impaction grafting in large defects has yielded conflicting results.

Methods: This was a retrospective study of a case series of five patients with a young age (≤50 years) at the time of surgery who had large acetabular defects reconstructed by bone impaction grafting and trabecular metal augments. The mean follow-up was 79 months.

Does preoperative psychologic distress influence pain, function, and quality of life after TKA?

Background: Preoperative psychologic distress is considered to be a risk factor for clinical dissatisfaction stemming from persistent pain and physical limitations after elective orthopaedic procedures such as lower-extremity arthroplasty. However, the degree to which psychologic distress, specifically in the form of anxiety and depression, influences surgical results has been poorly characterized.

Questions/purposes: We analyzed the effect of preoperative psychologic distress on changes in pain, function, and quality of life 1 year after elective TKA.

Validity of clinical diagnosis in dermatology.

Objective: We evaluated the accuracy of the clinical diagnostic process performed by dermatologists.

Material And Methods: We conducted a cross-sectional study, based on a retrospective search of data at a dermatology outpatient department. Fifteen skin diseases were selected.
