Background and Objectives: Tenosynovial giant cell tumor (TGCT) is a rare, locally aggressive, benign neoplasm arising from the synovium of joints, tendon sheaths, and bursa. There are two main subtypes of TGCT: localized-type TGCT(L-TGCT) and diffuse-type TGCT (D-TGCT). While surgical excision is still considered the gold standard of treatment, the high recurrence rate, especially for D-TGCT, may suggest the need for other treatment modalities. Materials and Methods: This study reviews current literature on the current treatment modalities for refractory-relapsed TGCT disease. Results: The gold standard of treatment modality in TGCT remains surgical excision of the tumor nevertheless, the elevated recurrence rate and refractory disease, particularly in D-TGCT indicates and underscores the necessity for additional treatment alternatives. Conclusions: TGCT is a benign tumor with inflammatory features and a potential destructive and aggressive course that can lead to significant morbidity and functional impairment with a high impact on quality of life. Surgical resection remains the gold standard current treatment and the optimal surgical approach depends on the location and extent of the tumor. Systemic therapies have been recently used for relapsed mainly cases.

Developing multiple soft tissue sarcomas (STSs) is a rare process, sparsely reported in the literature to date. Little is known about the pattern of disease development or outcomes in these patients. Patients were identified from three tertiary orthopaedic oncology centres in Canada and the UK. Patients who developed multiple extremity STSs were collated retrospectively from prospective oncology databases. A literature review using MEDLINE was also performed. Six patients were identified in the case series from these three institutions, and five studies were identified from the literature review. Overall, 17 patients were identified with a median age of 51 years (range: 19 to 77). The prevalence of this manifestation in STS patients is 1 in 1225. The median disease-free interval between diagnoses was 2.3 years (range: 0 to 19 years). Most patients developed the secondary STS in a metachronous pattern, the remaining, synchronously. The median survival after the first sarcoma was 6 years, and it was 1.6 years after the second sarcoma. The 5-year overall survival rate was 83.3% and 50% following the first and second STS diagnoses, respectively. A diagnosis of two STSs does not confer a worse prognosis than the diagnosis of a single STS. Developing a second STS is a rare event with no identifiable histological pattern of occurrence. Presentation in a metachronous pattern is more common. A high degree of vigilance is required in patients with a previous STS both to detect both local recurrence and to identify new masses remote from the previous STS site. Acquiring an early histological diagnosis should be attempted.

Bone infections, including osteomyelitis, prosthetic joint infections, and fracture-related infections, represent a persistent and growing clinical problem associated with substantial morbidity, mortality, and healthcare costs. Their management is complicated by limited bone vascularization, biofilm formation, intracellular bacterial persistence, dysregulated host immune responses and reduced antibiotic delivery to the infection site, which promote chronic infection and recurrence. The limitations of conventional treatment strategies based on surgical debridement and prolonged systemic antibiotic therapy, together with their association with antimicrobial resistance and systemic toxicity, have led to growing interest in alternative and adjunctive therapeutic approaches. Local antibiotic delivery systems, such as polymethyl methacrylate, calcium sulfate, hydroxyapatite-based composites, hydrogels, antibiotic-impregnated bone grafts, and nanoparticle carriers, enable high local antimicrobial concentrations while minimizing systemic exposure. From a different therapeutic perspective, immunomodulatory strategies, including mesenchymal stem cell-based therapies, cytokine-targeted interventions, bacteriophages, quorum-sensing inhibitors, and non-antibiotic antimicrobials, represent emerging approaches aimed at improving infection control and supporting bone regeneration. Advances in biomarker profiling, molecular diagnostics, and artificial intelligence-assisted analyses further support personalized approaches to diagnosis, monitoring, and treatment. Despite encouraging early results, clinical translation remains limited by methodological and regulatory challenges, underscoring the need for integrated, innovative treatment strategies.

Review of literature reveals that in Idiopathic Scoliosis (IS) children, the post-operative rib hump (RH) correction using full transpedicular screw construct has never been compared to hybrid constructs, applying the Rib-Index (RI) method. Therefore the aim of this report is to study which of the above two constructs offers better postoperative Rib Hump Deformity (RHD) correction.

The Rib Index, (RI), extracted from the double rib contour sign (DRCS) on lateral spinal radiographs to evaluate rib hump deformity, (RHD), in idiopathic scoliosis, (IS), patients, has been previously introduced. Although various papers using the RI have been published, no study on its reproducibility has been reported. The aim of this report is to estimate the variations of the RI in a number of a pair set of lateral chest radiographs (LCRs). The hypothesis was that the RI should have minimal variability for each subject having successive LCRs.
