These symptoms are manifestations of hyperplastic arthritis

Hyperplastic arthritis is a bone disease, usually caused by obesity, long-term physical work, and long-term excessive physical fatigue. People with hyperplastic arthritis are prone to joint pain, especially in the morning, and local redness and swelling will appear after work.

Hyperplastic arthritis symptoms

The main symptom is joint pain, which often occurs in the morning. The pain is relieved after activity, but the pain may worsen if there is too much activity. Another symptom is joint stiffness, which often occurs when you wake up in the morning or after the joints have been in a certain position for a long time during the day. Examination of the affected joints may reveal joint swelling and tenderness, and a friction or "clicking" sound during movement. In severe cases, muscle atrophy and joint deformities may occur.

Causes

Depending on the presence or absence of local and systemic pathogenic factors, osteoarthritis is divided into two categories: primary and secondary.

1. Secondary osteoarthritis

(1) Mechanical or anatomical abnormalities: abnormal development of the hip joint, slipped capital femoral epiphysis, femoral neck abnormalities, multiple epiphyseal dysplasia, old fractures, meniscectomy, joint replacement, acute or chronic injuries.

(2) Inflammatory joint diseases: suppurative arthritis, osteomyelitis, tuberculous arthritis, rheumatoid arthritis, seronegative spondyloarthropathies, Behcet's syndrome, and Paget's disease.

(3) Metabolic abnormalities: gout, Gaucher's disease, diabetes, progressive hepatolenticular degeneration, chondrocalcinosis, and hydroxyapatite crystals.

(4) Endocrine abnormalities: acromegaly, sex hormone abnormalities, hyperparathyroidism, hypothyroidism with myxedema, and adrenal cortex hyperfunction.

(5) Neurological defects: peripheral neuritis, syringomyelia, and Charcot arthropathy.

2. Primary osteoarthritis

The cause of the disease is still unclear, but it may be related to factors such as advanced age, female gender, obesity, and occupational overuse.

Differential Diagnosis

1. Rheumatoid arthritis

It usually occurs between the ages of 20 and 50. Severe acute attack, systemic symptoms are mild and last for a long time. The affected joints are often symmetrical or multiple, and the distal interphalangeal joints are not invaded. In the early stage, the joint swelling is fusiform, while in the late stage, there is dysfunction and ankylosis. X-ray examination shows local or systemic osteoporosis, joint surface absorption, bone healing ankylosis deformity. Laboratory examination showed increased erythrocyte sedimentation rate and positive rheumatoid factor.

2. Ankylosing spondylitis

It is more common in young and middle-aged men aged 15 to 30. The onset is slow, with intermittent pain and multiple joints affected. Spinal movement is limited, joint deformities occur, and there is morning stiffness. X-ray examination showed that the sacroiliac joint space was narrow and blurred, and the spinal ligaments were calcified, presenting bamboo-like changes. Laboratory tests showed that the erythrocyte sedimentation rate was increased or normal, and HLA-B27 was positive. Rheumatoid factor is mostly negative.
