Recently, the Department of Joint Surgery of Union Hospital Affiliated to Fujian Medical University admitted a patient and rarely removed nearly 300 chondromas from his hip joint, completing the difficult "Battle of Clear Stones".

The woman was in so much pain that she couldn't walk

The results of the examination surprised the doctors

Ms. Wang (pseudonym) is 10 years old this year, and a car accident 0 years ago caused her to suffer a severe fracture of her left hip joint, although it was surgically fixed, but the synovial tissue in the hip joint quietly "transformed" in the friction over the years.

Recently, hip pain has gradually worsened, which has seriously affected daily activities.

After going to many hospitals to no avail, Ms. Wang came to the Department of Joint Surgery of Union Hospital Affiliated to Fujian Medical University. "The joints seem to be filled with mud and sand, and every step is like moving in a pile of rubble."

Done by hip X-ray scan

The results surprised the doctors!

It turned out that Ms. Wang had nearly 2 synovial chondromas of different sizes in her hip cavity, with a maximum diameter of 0 cm. These "joint stones" cause severe osteoarthritis, where the femoral head is severely worn out and the joint space is almost gone.

X-ray scans showed that Ms. Wang's hip cavity was covered with synovial chondroma.

Eventually, Ms. Wang was diagnosed with hip synovial chondromatosis.

　　髖關節滑膜軟骨瘤病（SC）是一種多發生在關節腔內的罕見良性病變。發病率僅為1/10萬，多見於30~50歲的成年男性，男女發病比為3:1，多累及單關節，膝關節最常受累及，次之為肩、肘、髖關節。

Trauma is a predisposing factor, and multifunctional mesenchymal stem cells in the intrasynovial bursal tissue metaplases to cartilage, forming cartilage or bone-cartilage loose bodies. There is no specificity in the early stage, the hip joint is soreness and discomfort after activity, hip pain may occur with the aggravation of the disease, and the hip joint movement is limited in the late stage, in which flexion and external rotation are more common.

Surgical reconstruction of the joint

In view of Ms. Wang's condition, the attending doctor formulated a personalized surgical plan - left artificial total hip arthroplasty + synovial chondromatosis lesion removal + loose body removal + acetabular fracture internal fixation and removal.

In the end, the operation was successfully completed, and all the chondroma in Ms. Wang's hip cavity was removed.

Postoperative follow-up images showed that Ms. Wang's chondroma had been completely removed.
