Ga-labeled prostate-specific membrane antigen (PSMA) is a potential tool in the imaging of recurrent prostate cancer. Ga-PSMA imaging is also useful for radiotherapy planning and in targeted therapy with Lu-PSMA. A few case reports regarding the use of Ga-PSMA in nonprostate cancer malignancies are also reported. We describe the use of Ga-PSMA imaging before Sm-EDTMP bone pain palliation therapy in a 58-year-old hormone refractory prostate cancer patient with extensive bone metastases.

The December 2024 US Food and Drug Administration (FDA) approval of Mesoblast's Ryoncil (remestemcel-L-rknd)-allogeneic bone marrow mesenchymal stromal cell (MSC(M)) therapy-in pediatric acute steroid-refractory graft-versus-host-disease finally ended a long-lasting drought on approved MSC clinical products in the United States. While other jurisdictions-including Europe, Japan, India, and South Korea-have marketed autologous or allogeneic MSC products, the United States has lagged in its approval. The sponsor's significant efforts and investments, working closely with the FDA addressing concerns regarding clinical efficacy and consistent MSC potency through an iterative process that spanned several years, was rewarded with this landmark approval.

A patient in his 40s presented at the outpatient clinic with sudden pain and swelling over his medial malleolus, 16 weeks after he had undergone osteoperiosteal autografting with a medial malleolar osteotomy for his tertiary osteochondral lesion of the talus. Postoperatively, the patient was treated using the regular evidence-based rehabilitation protocol of 5 weeks of non-weight-bearing and 5 weeks of partial weight-bearing. However, after the confirmed radiological union the patient experienced an acute on chronic stress fracture through the osteotomy line.

Background: Humeral capitellar osteochondritis dissecans (OCD) lesions can be challenging to treat. Past studies have demonstrated grafting with extracellular matrix with bone marrow aspirate concentrate (ECM-BMAC) to be a viable technique for treatment of talar dome OCD, though little literature exists regarding application of this technique to the capitellum. This study aimed to report patient-reported outcomes (PROs) and return to sport (RTS) of pediatric patients at ≥1-year postoperatively who underwent ECM-BMAC grafting for capitellar OCD lesions.

Department of Orthopedic surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea. Electronic address:
Background: Heterotopic ossification (HO) involves abnormal bone formation in soft tissues near joints, commonly occurring after elbow trauma or surgery, leading to pain and functional limitations. Previous studies have primarily characterized HO distribution based on bony landmarks, lacking a detailed investigation into the characteristics of its distribution in periarticular soft tissue in post-traumatic elbows. This study aimed to (1) develop a muscle-guided classification system using computed tomography (CT) to map HO relative to elbow muscle-tendon units and (2) investigate correlations between HO location and severity.

Purpose Of Review: Low back pain (LBP) is considered an important issue of public health, with annual prevalence estimations almost achieving 60% of the worldwide population. Available treatments have a limited impact on this condition, although they allow to alleviate pain and recover the patient's quality of life. This review aims to go deeper on the understanding of this condition, providing an updated, brief, and concise whole picture of this common musculoskeletal problem.
