Tibial tuberosity swelling

Introduction The swelling of the humerus, pain, exercise, or aggravation when going up and down the stairs is one of the clinical manifestations of humeral osteophyte. More common in 14-18 year old male teenagers who like sports.

Cause

When adolescents are strenuously exercising, the strength of the quadriceps muscles frequently contracts, and the humeral humerus is pulled through the patellar tendon. The department is susceptible to cumulative damage. Increases the internal pressure of the tissue and causes blood flow disorders, causing ischemic necrosis. Suffering from humeral bursal bursitis, the cause is mainly related to strain, wind, cold and dampness attack or traumatic sequelae. Liver and spleen are not balanced with transport, and the bones are not well-fed.

an examination

X-ray examination of mammography

(1) There is a history of strenuous exercise. The humerus is swollen, painful, aggravated when moving or going up and down the stairs. After the break, it can be quickly reduced.

(2) The knee extension resistance test is positive.

(4) Palpation: The bulge of the bulge is hard, does not move, and does not adhere to the skin. Mild tenderness, slightly higher skin temperature.

X-ray inspection:

(1) There is no special change in early bone mass, and there may be soft tissue swelling in the trochanter.

(2) In the middle stage, the distance between the humeral epiphysis and the humerus was widened, and the patellar ligament became thick and blunt in the trochanter.

(3) In the later stage, the density of the humerus can be seen to increase, and in severe cases, there may be fragmentation or tongue-like lifting.

Differential diagnosis

Differential diagnosis of sacral trochanter swelling:

1, the formation of bone pseudoarthrosis: congenital sacral pseudoarthrosis is a general term for congenital tibia formation or failure, there are many specific types, each type has its own pathology, disease course and prognosis, more common in the lower third of the humerus At the junction, a local pseudo joint is eventually formed. The incidence rate of males is slightly higher than that of females, mostly unilateral, and the ipsilateral tibia can also be involved. A small number of patients have a genetic history.

2, normal tibial tuberosity variation: the blood supply of the tibial tuberosity is from the patellar ligament artery, after the occurrence of ischemic necrosis, it can cause the ligament of the patellar tendon and soft tissue and the enlargement of the tibial tuberosity. The accessory bursa caused by the protrusion is inflamed. It is the cause of swelling of the soft tissue of the tibial tuberosity. Normal tibial tuberosity is highly variable, and there may be multiple ossification centers with different shapes.
