What is Achondroplasia?

Osteochondrosis is a non-inflammatory disease of ossification of articular cartilage and patellar cartilage. The common osteochondrosis clinically are as follows: detached osteochondrosis; the elbow process is not closed; the ulna coronoid process is split;

Basic Information

English name

osteochondrosis

Visiting department

orthopedics

Common locations

Articular cartilage and patellar cartilage

Common symptoms

Lameness, pain, muscle atrophy, no swelling in the affected area, etc.

Causes of osteochondrosis

It is not clear and may be related to trauma, infection and insufficient local blood supply. It may also be related to congenital factors and to excessive growth.

Clinical manifestations of osteochondrosis

Lameness, pain, but no history of injury; often bilateral bilateral symptom onset, the course of the disease develops slowly, and the cartilage or osteochondral structure has changed significantly when symptoms appear. Lameness worsens after exercise and worsens after a long break. The affected elbow muscles atrophied without swelling in the affected area. Arthrocentesis was normal or mixed with cartilage fragments.

There are several common osteochondrosis clinically:

Isolated osteochondrosis

The articular cartilage is abnormally thickened and cracked, and then separated from the subchondral bone, forming a cartilage flap or a free cartilage slice. It is mainly found in the shoulder joint (the posterior edge of the humeral head), the elbow joint (the internal condyle of the humerus), the knee joint (the internal femoral condyle), and the ankle (the talus tackle).

2. The elbow process is not closed

The ossification center of the elbow process and the proximal iliac crest of the ulna are not closed for a long time (the epiphyseal growth plate cartilage does not ossify), which makes the elbow joint unstable and is easy to secondary to osteoarthrosis of the elbow joint.

3. Coronoid process of ulna

Coronoid process of ulna is divided into several pieces without healing with ulna, which can easily induce osteoarthritis.

4. Delayed ossification of growth plate

The secondary ossification center of the long bone, such as the sacral growth plate of the distal ulnar ossification center, is retarded, resulting in asynchronous growth with the radius, leading to angular deformity of the radius or subluxation of the elbow joint.

Osteochondrosis examination

Feasible bone density examination and X-ray examination. X-ray examination showed invasion of articular cartilage bone, abnormal ossification of palate growth plate, or long bone deformation.

Osteochondrosis diagnosis

It is not difficult to draw a diagnosis based on clinical manifestations and related examinations.

Differential diagnosis of osteochondrosis

Should be distinguished from rickets.

Osteochondrosis complications

Juvenile vertebral osteochondrosis often occurs in the rapid growth period of adolescents. The main reason for the majority of patients to see a doctor is humpback deformity. Some of these patients may have back pain,

50% of patients complain of pain, mainly in the deformity or lower back. Aggravated after the event. It usually decreases with the end of growth, and only a small number of patients have more typical symptoms after near maturity. If the pain is located in the waist and the deformity is in the chest, the possibility of pedicle fracture should be considered.

Osteochondrosis Treatment

Take more rest, less exercise, and give painkillers symptomatic treatment when the pain is severe. If there is free cartilage film in the joint, it must be removed surgically, and those with angular deformities can be corrected by surgery. Symptoms generally ease after adulthood, but osteoarthropathy is often secondary, so complete recovery is unlikely.
