Stump fracture

Introduction Residual plant fracture is a type of calcaneal fracture. The most common fracture of the calcaneus fracture is the middle-aged male. Residual plant fractures: longitudinal (oblique) fractures of the distance and the heel joint.

Cause

More adults, often falling from high places or crushing and causing injuries. Often accompanied by spinal fractures, pelvic fractures, head, chest, and abdominal injuries, do not make mistakes at the time of initial diagnosis. The calcaneus fracture is the most common type of humeral fracture, accounting for about 60% of all tibiofibular fractures. Most fall from the height, the foot touches the ground, and the heel suffers from vertical impact.

(1) When the longitudinal fracture of the calcaneus nodule is mostly high, the bottom of the heel valgus nodule is grounded, and the medial ridge of the nodule is caused by shearing external force. It is rarely shifted and generally does not need to be processed.

(2) The level of calcaneus nodule (bird's beak) is a kind of avulsion fracture of Achilles tendon. If the avulsed bone is small, it will not affect the Achilles tendon function. If the fracture piece exceeds 1/3 of the nodule, and there is rotation and severe inclination, or if the upward traction is severe, the operation can be reset and the screw is fixed.

(3) When the calcaneus fracture is a varus, the carrier is caused by the impact of the talus in the lower part of the talus. It is rare. Generally, there is not much displacement. If there is displacement, the thumb can be used to push it back to the original position, and the short leg plaster is fixed for 4-6 weeks.

(4) The fracture of the anterior calcaneus is less common. The injury mechanism is a strong adduction of the forefoot plus a plantar flexion. The X-ray oblique slice should be taken to exclude the anterior humeral fracture of the calcaneus, and the short leg cast can be fixed for 4-6 weeks.

(5) The fracture close to the joint is a fracture of the calcaneus. The injury mechanism is also caused by the high point falling down with the bone, or the heel being affected by the counter-impact force from below. The fracture line is oblique. When the X-ray film is viewed from the front, the fracture line is inclined from the inside to the outside, but not through the joint surface. Because the calcaneus is cancellous, the axial position is widened on both sides of the humerus; the lateral image, the posterior half of the calcaneus and the calcaneal nodule are displaced backwards, causing the calcaneus to protrude to the center of the foot. It is rocking chair.

CT examination of bones and joints of limbs and joints

First, physical examination

Taking a medical history gives us a first impression and revelation, and also guides us to a concept of the nature of the disease.

Second, imaging performance check

Laboratory examinations must be summarized and analyzed based on objective data learned from medical history and physical examination, from which several diagnostic possibilities may be proposed, and further consideration should be given to those examinations to confirm the diagnosis.

For example, the x-ray positive, lateral, and axial slices can clearly define the nodule joint angle of the calcaneus and its transverse diameter.

Differential diagnosis

Diagnosis: X-ray plain film (including positive, lateral and calcaneus axial slices) can generally be diagnosed. CT scan or MRI can be performed in patients with difficult diagnosis, especially CT scan in the diagnosis and prognosis of fracture classification. Larger.

Differential diagnosis:

Abductive fractures: upper limb abduction during fall, palms on the ground, and indirect violent upward conduction leading to fractures. The proximal end of the fracture is adducted and distally abducted, forming a forward or inward angular deformity or a misaligned deformity. More common in clinical practice.

Adduction fracture: Contrary to abduction fracture, the hand or elbow touches the ground when the fall, the upper limb adducts, the proximal end of the fracture abducts, the distal adduction, forming an outward angular deformity. Less common.

Tongue fracture: Tongue type fracture of calcaneus fracture: caused by multiple vertical violence.
