In children, the results of early treatment are always good, typically normal or nearly so. The elbow joint is particularly susceptible to loss of motion. It promotes stability of the radial head dislocation and allows very early mobilisation to prevent stiffness. Osteosynthesis (open reduction and internal fixation) of the ulnar shaft is considered the standard of care in adults. Monteggia fractures may be managed conservatively in children with closed reduction (resetting and casting), but due to high risk of displacement causing malunion, open reduction internal fixation is typically performed. IV - Combined type (5%) - ulna shaft and radial shaft are both fractured and radial head is dislocated, typically anteriorly.III - Lateral type (20%) - ulna shaft angulates laterally (bent to outside) and radial head dislocates to the side.II - Flexion type (15%) - ulna shaft angulates posteriorly (flexes) and radial head dislocates posteriorly. I - Extension type (60%) - ulna shaft angulates anteriorly (extends) and radial head dislocates anteriorly.There are four types (depending upon displacement of the radial head): Bado Classification - Monteggia Fractures It is called a 'nightstick fracture'.ĭiagnosis Classification Such an isolated ulnar shaft fracture is not a Monteggia fracture. In this context, isolated ulnar shaft fractures are most commonly seen in defence against blunt trauma (e.g. Direct blow on back of upper forearm would be a very uncommon cause.Depending on the impact and forces applied in each direction, degree of energy absorption determines pattern, involvement of the radial head and whether or not open soft tissue occurs. The ulna fractures in the proximal one-third of the shaft due to extreme dislocation. Fall outstretched hand with the forearm in excessive pronation (hyper-pronation injury).It is named after Giovanni Battista Monteggia. The Monteggia fracture is a fracture of the proximal third of the ulna with dislocation of the proximal head of the radius.
