A 36 years old gentleman had giant cell tumour (GCT) in distal ulna for which he underwent resection of distal half of ulna but developed recurrence of the tumour. Following proper evaluation (grading and staging), he underwent wide margin excision of tumour including removal of distal three-fourth of ulna and reconstruction by free vascularised osteocutaneous fibular transfer. The distal reconstructed fibula was stabilized with extensor carpi ulnaris (ECU). Two years after the surgery, he developed a metachronous GCT lesion in ipsilateral distal radius for which he had curettage and bone grafting with preservation of articular surface.

Case: A 52-year-old male fell from his bike and sustained fractures of the right proximal humerus and the left distal radius, both of which were fixed in a single sitting a day after the injury. On postoperative day four, the patient developed features suggestive of acute pulmonary embolism.
Conclusion: Reports of acute pulmonary embolism developing after surgical fixation of bilateral upper extremity fractures are rare.

High resolution peripheral quantitative computed tomography (HRpQCT) offers detailed bone geometry and microarchitecture assessment, including cortical porosity, but assessing chronic kidney disease (CKD) bone images remains challenging. This proof-of-concept study merges deep learning and machine learning to 1) improve automatic segmentation, particularly in cases with severe cortical porosity and trabeculated endosteal surfaces, and 2) maximize image information using machine learning feature extraction to classify CKD-related skeletal abnormalities, surpassing conventional DXA and CT measures. We included 30 individuals (20 non-CKD, 10 stage 3 to 5D CKD) who underwent HRpQCT of the distal and diaphyseal radius and tibia and contributed data to develop and validate four different AI models for each anatomical site.

BACKGROUND Extensor pollicis longus (EPL) tendon rupture is a potential complication following distal radius fracture, typically occurring several weeks after injury. Herein, we present a rare case of acute extensor pollicis longus tendon rupture associated with a distal radius fracture. CASE REPORT A 35-year-old woman visited our hospital with a distal radius fracture.
