Hereditary haemochromatosis (HH) is a genetic iron overload condition caused most commonly by C282Y homozygous mutation in the HFE gene. The excess iron accumulates in organs and tissues including the liver, heart, pancreas, and joints. Joint involvement is one of the most common and most debilitating complications, affecting up to 40-60% of patients with HH, and is often the presenting symptom that leads to diagnosis.
How Haemochromatosis Affects Joints and Mobility
Haemochromatotic arthropathy: Iron deposition in joint synovium and cartilage causes a distinctive arthropathy. Unlike standard OA or RA, haemochromatotic arthropathy has a predilection for the metacarpophalangeal joints (knuckles) and the second and third MCP joints specifically -- a pattern not seen in rheumatoid arthritis or psoriatic arthritis. In the lower limbs, the ankle and knee can be affected.
Chondrocalcinosis: Calcium pyrophosphate crystal deposition (pseudogout) is associated with HH and causes acute episodic arthritis on top of the chronic arthropathy. Acute attacks in the knee or ankle are severely limiting and may require the cane specifically during attack periods.
Secondary OA: Chronic haemochromatotic arthropathy damages cartilage and leads to secondary OA. Hip OA secondary to HH arthropathy is a recognised complication.
Diabetes (haemochromatotic): Iron deposition in the pancreas causes diabetes in a proportion of HH patients -- adding diabetic peripheral neuropathy to the potential lower limb impairments.
Treatment and Joint Outcomes
Venesection (regular phlebotomy to remove iron-loaded red cells) is the primary HH treatment and effectively prevents or reverses organ damage if started before significant deposition occurs. However, established arthropathy is largely irreversible even with adequate venesection -- the joint damage that has occurred does not repair. For patients diagnosed after significant joint disease is established, the arthropathy and its mobility consequences persist despite treatment.
When to Consider a Cane in HH
| Joint Involvement | Pattern | Cane Indication |
|---|---|---|
| Lower limb arthropathy (ankle, knee) | Chronic, ongoing | Regular use as for OA of these joints |
| Acute pseudogout attack (lower limb) | Acute episode, typically 1-3 weeks | During attack; wean as episode resolves |
| Secondary hip OA | Progressive | Contralateral cane as for hip OA |
| Diabetic neuropathy (concurrent) | Progressive | As per diabetic neuropathy guidance |
Hand Involvement and Grip
HH arthropathy affects MCP joints in the hands more predictably than most other arthritides. This is relevant for cane handle selection: MCP joint pain from HH arthropathy makes standard narrow handles painful. The Anatomic Grip distributes load across the palm, reducing MCP joint stress during cane use. See also the related guide on cane handles for hand conditions.
