What is a Monteggia fracture?
A Monteggia fracture-dislocation refers to dislocation of the radial head (proximal radioulnar joint) with fracture of the ulna.
How long does a broken Monteggia take to heal?
The recovery time is 6–12 weeks. A mild hyperextension deformity is seen in 39–45% of children after Monteggia fracture-dislocation.
How do you prevent Monteggia?
– posterior Monteggia frx is reduced by applying traction to forearm w/ the forearm in full extension; – immobilization is continued until there is union of the ulna; – this ordinarily requires 6-10 wks depending on the age of pt; – ref: Repair of Bado II Monteggia Fracture: Case Presentation and Surgical Technique.
How do you fix a broken Monteggia?
Treatment: There are 3 important things to keep in mind when treating a monteggia fracture. You must correct the ulna deformity, reduce the radial head, and minimize future forces that may cause the radial head to re-dislocate. Treatment is often dictated by the pattern of the ulna fracture (Ring, 1998; Ramski, 2015).
Which nerve is damage in Monteggia fracture?
Posterior interosseous nerve palsy is the most common nerve injury in Monteggia fracture-dislocations,. Most of these injuries are neuropraxia and recover slowly after the anatomical reduction of the radial head.
Does Monteggia fracture require surgery?
Anatomic reduction of the ulna is usually required before radial head reduction. Unless the fracture is open, surgical treatment is performed on an elective basis. Whereas most adults require operative treatment, most pediatric fractures are treated with closed reduction.
How do you fix a broken monteggia?
Comminuted or long oblique ulna fractures are fixed by ORIF using plates and screws. Operative management is crucial for the majority of adult Monteggia fractures. Adults are more prone to the persistent angulation and shortening despite closed reduction techniques. The most common operative repair is an ORIF.
What is a a Monteggia fracture?
A Monteggia fracture is defined as a proximal 1/3 ulna fracture with an associated radial head dislocation. Diagnosis is made with forearm and elbow radiographs to check for congruency of the radiocapitellar joint in the setting of an ulna fracture.
What is a Monteggia lesion on a dog?
Ulnar fracture with dislocation of the proximal epiphysis of the radius (Monteggia lesion) was diagnosed in 16 dogs and 12 cats. The lesions were classified into 4 types on the basis of direction of the dislocation of the radial head and angulation of the ulnar fracture.
What is a Galeazzi fracture dislocation of the forearm?
Some fractures of the forearm are coupled with a dislocation of the joint proximal or distal to the fracture. A fracture of the ulna with a dislocation of the radial head is called a Monteggia fracture dislocation. A fracture of the radius with a disruption/dislocation of the distal radioulnar joint is called a Galeazzi fracture dislocation.
What are the surgical approaches to ulna fractures in dogs?
