Introduction

Introduction Diagnosis of double fractures of the ulnar and ulnar shaft: pain and activity disorder after forearm trauma, X-ray films can determine the type of fracture and displacement. The photo should include the elbow and wrist joints to understand the presence or absence of rotational displacement and dislocation of the upper and lower ankle joints. The main symptoms of this disease are local swelling, deformity and tenderness, bone rubbing and abnormal activities, and restricted forearm activity. Children often have green branch fractures, with angular deformities and no bone displacement. Sometimes combined with median nerve or ulnar nerve, radial nerve injury, should pay attention to check.

Cause

Cause

The disease is caused by arm trauma, and different violent factors can cause different types of fractures:

1, direct violence: more common in combat or mechanical injury, fractures are horizontal or smashed, the fracture line is in the same plane.

2. Indirect violence: When the person falls, the palm of the hand touches the ground, and the violence causes the fracture to occur in the middle or upper third of the humerus. The residual violence is transmitted obliquely down to the ulna through the interosseous membrane, causing the ulnar fracture, so the ulnar fracture line is lower than the tibial fracture line. Most of the humeral fractures are transverse or serrated, and the ulna is mostly short oblique.

3. Reverse the violence: When the body falls, the body leans to one side, and the forearm is simultaneously subjected to the longitudinal conduction and the rotational torque, and the spiral fracture of the ulnar and radial bone occurs. The direction of the fracture line is the same, and there are many ulnar bones that are inclined to the lower part of the humerus.

[clinical manifestations]

The main symptoms of this disease are local swelling, deformity and tenderness, bone rubbing and abnormal activities, and restricted forearm activity. Children often have green branch fractures, with angular deformities and no bone displacement. Sometimes combined with median nerve or ulnar nerve, radial nerve injury, should pay attention to check.

diagnosis

Pain after the trauma of the forearm, movement disorder, X-ray film can determine the type of fracture and displacement. The photo should include the elbow and wrist joints to understand the presence or absence of rotational displacement and dislocation of the upper and lower ankle joints.

Diagnosis

Differential diagnosis

The disease is caused by traumatic factors. The fracture damage here can often be combined with the bone damage of other joints. Therefore, it is necessary to identify the possible fracture injuries:

1. Ulnar fracture.

2, fracture of the tibia.

A differential diagnosis can usually be made using X-ray examination.
