Humeral Tubercle Fracture in Children: Treatment and Recovery
Upper shoulder girdle injuries are common in children. Among these, humeral tubercle fractures deserve special attention, as this area is the attachment site for the most important muscles responsible for arm rotation and abduction.
Proper treatment of a humeral tubercle fracture allows for full restoration of limb function and the return of the child to their normal lifestyle.

Causes and mechanisms of injury
A child's shoulder injury can result from a direct blow or indirect impact through the muscles.
Falling on the Arm or Shoulder
Most often, such injuries occur due to a fall on an outstretched arm or on the outer surface of the shoulder joint. This causes a sharp impact of the head of the humerus on the acromion.
Sports Injury and Sudden Muscle Contraction
A sudden contraction of the rotator cuff muscles causes a bone fragment to break off. This occurs with sudden throws, powerlifting, or falls during competitions.
Fracture Associated with Shoulder Dislocation
A fracture of the humeral tubercle often accompanies an anterior shoulder dislocation. When the head of the humerus leaves the glenoid cavity, the tubercle strikes the edge of the scapula and breaks off.
Symptoms and first signs
Symptoms of a humeral tuberosity fracture aren't immediately apparent. Children can't always explain exactly what's hurting them. Therefore, parents need to pay attention to external signs and their child's mood.
Pain and limited movement
Sharp shoulder pain is the first symptom. It intensifies when attempting to raise the arm to the side or rotate it inward.
Swelling, bruising, and tenderness to the touch
Swelling in this area increases rapidly. The muscles tense, and after a few hours, bruising may appear, gradually moving lower toward the elbow.
When should you urgently take your child to the doctor?
Take your child to the emergency room if the following signs are observed:
- Severe deformity of the shoulder joint
- Numbness of the hand or fingers
- Coldness of the skin of the injured limb
- No pulse in the wrist
- Increasing, intractable pain
First Aid Before Seeing a Doctor
The quality of first aid directly affects the subsequent treatment of a humeral tubercle fracture.
Parents should:
- Immobilize the arm: secure it to the body with a sling.
- Apply ice to the injured area for 15–20 minutes.
- Give the child an age-appropriate dose of pain reliever (paracetamol or ibuprofen).
- Reassure the child and limit their movements until the doctors arrive.
How to safely immobilize the arm.
For immobilization A triangular piece of cloth (sling) is best. The arm is bent at the elbow at a 90-degree angle, the forearm is placed in the loop of the sling, and the ends are tied around the neck. Proper immobilization reduces the risk of increased displacement of the fracture fragments during transport.
What can be done to reduce pain and swelling
Cold is the most effective way to reduce swelling in the first few hours. It causes vasospasm, which reduces internal bleeding in the fracture area. Painkillers help relieve general stress in the body.
What should not be done on your own
If there is a shoulder dislocation in combination with a fracture, rough manipulation can damage the axillary nerve or main artery. Do not use warming ointments, alcohol compresses, or massage.
General information
Diagnosis
Accurate diagnosis is the key to successful treatment of a shoulder fracture in children and does not lead to disability.
Examination by a traumatologist-orthopedist
A pediatric traumatologist-orthopedist performs an initial examination. They evaluate vascular pulsation and finger and skin sensitivity. The doctor checks the symmetry of the joints and identifies characteristic bony protrusions.
X-ray of the shoulder
The primary imaging method is an X-ray of the shoulder. Images are taken in at least two projections (AP and axial). On the X-ray, the doctor can see the fracture line and determine the distance the bone fragment has traveled.
When is a CT or MRI needed?
X-rays do not always provide a complete picture of the injury. In such situations, the doctor prescribes additional tests:
- CT scan: needed to examine bone fragments and plan surgery
- MRI: needed if there is a suspected ligament or muscle rupture or labral damage
Frequently Asked Questions
How is a humeral tuberosity fracture treated in children?
How long does it take for a humeral tuberosity fracture to heal in a child?
When is surgery necessary for this type of fracture?
Can I return to sports after treatment?
Yes, but only after the doctor confirms bone healing and the child has regained muscle tone. Typically, exercise is not permitted until 3-6 months after the injury.
A humeral tubercle fracture in children is not a particularly serious injury. But this doesn't mean you can ignore the doctor's orders.
Treatment of a humeral tubercle fracture and a responsible approach to rehabilitation are the key to quickly restoring a child's health.

What is a humeral tubercle fracture and why does it occur in children?
The largest part of the humerus is the greater tubercle of the humerus. It is located on the lateral surface and serves as an attachment point for the supraspinatus, infraspinatus, and teres minor muscles.
How the greater tubercle of the humerus is structured
The greater tubercle of the humerus is the area where tendons attach. In children, this area is closely connected to the growth plates (epiphyseal plates), which are responsible for bone growth.
How this injury differs in childhood
In children, the bones are more elastic, and the periosteum is thick and strong. Often, a humerus fracture in a child is a "greenstick" or avulsion fracture. Since the ligaments in children are often stronger than the bones themselves, a sharp jerk or impact causes the muscle to "tear" a piece of the bony protrusion rather than tearing it. Another important feature is a high metabolic rate, which allows bone fusion to occur more quickly than in adults.
