Bone is living tissue that is constantly broken down and rebuilt. Bone diseases disturb that balance or damage bone directly. The main groups are metabolic diseases (osteoporosis, osteomalacia and rickets, Paget disease, bone disease from kidney failure or overactive parathyroid glands), infection (osteomyelitis), loss of blood supply (avascular necrosis), tumours (benign, primary malignant and spread from other cancers) and inherited disorders such as osteogenesis imperfecta.
These conditions have different causes and treatments, so an accurate diagnosis comes first. Osteoporosis is by far the most common and is silent until a bone breaks. Many bone diseases can be controlled well with medication; lost height or a collapsed joint surface cannot be put back, which is the argument for finding them early.
Symptoms
- A fracture after a minor fall or no fall at all
- Loss of height or a stooped upper back
- Deep, persistent bone pain, often worse at night
- Bone tenderness and muscle weakness, typical of osteomalacia
- Bowed legs or delayed walking in children with rickets
- Groin pain and limp in avascular necrosis of the hip
- A swelling or lump on a bone
- Fever with localised bone pain in infection
Causes and risk factors
Osteoporosis follows oestrogen loss after menopause, ageing, long-term steroid treatment, low body weight, smoking, heavy alcohol use and conditions such as coeliac disease or overactive thyroid. Osteomalacia and rickets come from lack of vitamin D, through little sun exposure, covered skin, malabsorption or kidney and liver disease. Paget disease has genetic and possibly viral contributors. Avascular necrosis is linked to steroids, alcohol, sickle cell disease and hip fracture. Osteomyelitis is usually bacterial. Most cancers found in adult bone have spread from the breast, prostate, lung, kidney or thyroid.
How it is diagnosed
- Blood tests: Calcium, phosphate, vitamin D, parathyroid hormone, alkaline phosphatase, kidney function and inflammatory markers separate the metabolic causes.
- DEXA bone density scan: Measures density at the hip and spine to diagnose osteoporosis and estimate fracture risk.
- X-rays: Show fractures, deformity, the coarse thickened bone of Paget disease and many tumours.
- MRI: The most sensitive test for early avascular necrosis, infection, stress fractures and marrow disease.
- Bone scan or PET-CT: Surveys the whole skeleton for multiple areas of disease.
- Bone biopsy: Confirms a tumour or infection and identifies the organism or cell type.
Treatment options
- Vitamin D, calcium and lifestyle: Correcting deficiency, weight-bearing exercise, stopping smoking and reducing falls underpin most bone care.
- Bisphosphonates and denosumab: Slow bone breakdown in osteoporosis; bisphosphonates also control Paget disease.
- Bone-building drugs: Teriparatide or romosozumab for severe osteoporosis with fractures.
- Antibiotics and surgical cleaning: Several weeks of targeted antibiotics, with removal of dead bone when needed, for osteomyelitis.
- Joint-preserving surgery or joint replacement: Core decompression for early avascular necrosis; replacement once the joint surface has collapsed.
- Tumour treatment: Observation, curettage or wide resection with reconstruction depending on type, with chemotherapy or radiotherapy for certain cancers.
- Fracture fixation and vertebral augmentation: Surgical stabilisation of fragility fractures and, for selected painful spinal fractures, cement procedures.
When it is urgent
Get emergency care locally for a suspected fracture, inability to bear weight after a fall, bone pain with high fever, or back pain with leg weakness, numbness around the saddle area or loss of bladder or bowel control. Relentless night pain with weight loss needs prompt investigation, not a long wait.
Travelling to Türkiye for treatment
A visit suits a defined piece of work: a bone health assessment with DEXA and blood tests, a second opinion on scans or a biopsy result, or planned surgery such as a hip replacement for avascular necrosis. Osteoporosis treatment runs for years with periodic monitoring, and bone infection needs weeks of supervised antibiotics, so both need a doctor near home. Bone cancer care should be led by a specialist sarcoma team; a trip may contribute an opinion or an operation within that plan.

Frequently Asked Questions
Is osteoporosis the same as osteoarthritis?
No. Osteoporosis is thin, fragile bone and causes no pain until a fracture. Osteoarthritis is wear of the joint and causes pain and stiffness.
Who should have a bone density scan?
Women over 65, men over 70, and younger people with a fragility fracture, long-term steroid use or other strong risk factors.
Does bone pain mean cancer?
Usually not. Most persistent bone pain has a benign cause, but unexplained night pain should be investigated.
Can weak bones be rebuilt?
Medication can increase density and roughly halve fracture risk in many cases, though bone does not return to youthful strength.
