• disproportionately
• osteophyte-like features on the ulna
• reduced trabecular bone in the metaphysis below the displaced growth plate
• shorter and wider
• in the humerus likely due to increased mechanical loading
• increased structural modeling index
• reduced trabecular bone in the metaphysis below the displaced growth plate
• contains chondrocytes with multiple distended cytoplasmic vacuoles, increased ratio of the number of cells with chondroptotic nuclei and enlarged endoplasmic reticulum with amorphous inclusions
• contains chondrocytes with multiple distended cytoplasmic vacuoles, increased ratio of the number of cells with chondroptotic nuclei and enlarged endoplasmic reticulum with amorphous inclusions
• abnormal joint between the humerus, ulna and radius with restricted articulation and osteophyte-like features
• flattened by P26 with reduced distance between the articular cartilage and the proximal humeral growth plate
• displacement of the proximal humeral epiphysis and bridging of the growth plate at 9 to 12 weeks
• premature closure by P56
• impaired chondrocyte development
• loss of growth plate polarity and organization by P14
• growth plates lack columns of proliferating chondrocytes and hypertrophic chondrocytes
• wider at P28 and P56
• the ossification zone is shorter than in control mice by P26
• impaired formation of secondary ossification centers by P14
• abnormal joint between the humerus, ulna and radius with restricted articulation and osteophyte-like features
