Osteomalacia And Rickets Notes

Medicine Notes > Orthopaedics Notes

This is an extract of our Osteomalacia And Rickets document, which we sell as part of our Orthopaedics Notes collection written by the top tier of University Of Leicester students.

The following is a more accessble plain text extract of the PDF sample above, taken from our Orthopaedics Notes. Due to the challenges of extracting text from PDFs, it will have odd formatting:

Osteomalacia and Rickets Normal amount of bone but reduced mineral content Rickets occurs if this happens during bone growth Osteomalacia occurs if this happens after fusion of epiphyses. Types Vitamin D deficiency (dietary inadequacy, lack of sunlight or malabsorption) Renal + liver osteomalacia (decreased hydroxylation of vit D) Drug induced Inherited vitamin D resistance Clinical features Rickets
- Knock-kneed
- Bow-legged
- Hypocalcaemia
- Enlargement of ends of long bones, widened cranial sutures Osteomalacia
- Bone pain (proximal limb girdles and lower back)
- Fractures
- Proximal myopathy
- Decreased phosphate Investigations Bloods: low calcium, phosphate. Increased alk phos, PTH. Decreased vit D Biopsy: shows poor mineralisation Xray
- In Rickets - cupped metaphyseal surfaces
- In Osteomalacia - Looser's zones/pseudofractures = translucent bands at sites of stress e.g ribs, scapula + pubic rami Management
- Treat any underlying cause
- Give oral daily vit D supplements
- Hydroxylated supplements if renal/liver disease
- Treatments relieve symptoms and correct bony abnormality in 3-4 months
