M80-M94: Osteopathies and chondropathies

M86-M90: Other osteopathies

The group of conditions, Other Osteopathies, encompasses various bone disorders outside of the usual categories of fractures, infections, and tumors. These conditions are often caused by diverse factors including genetic mutations, hormonal imbalances, nutritional deficiencies, certain drugs, or unknown causes. Symptoms generally revolve around pain, decreased mobility, changes in bone shape or size, and may also include systemic effects like fatigue or weight loss. Often, the onset is gradual, and the progression of the disease can lead to significant functional limitations depending on the affected body region. The skeletal system is primarily affected by these conditions, but they can also have secondary effects on other body systems, for example, causing respiratory issues in the case of rib abnormalities, or digestive issues due to pelvic malformations.
