Radial Head Dislocation
Dislocation of the Radial Head

Presentation

We present an unusual case of an isolated interosseous membrane disruption of the forearm without any fracture pattern. Dislocation of both radial head and distal radio-ulnar joint was presented. [ncbi.nlm.nih.gov]

Early on, pain is rare, if present at all. [musculoskeletalkey.com]

We present one of this rare case here. Case report A 26-year old man presented to us 8 weeks after injury to his right elbow with a motorbike accident. [jocr.co.in]

Treatment

All patients underwent surgical treatment and evaluation of radial head reduction and range of motion pre- and postoperatively. [ncbi.nlm.nih.gov]

Nonsurgical treatment has recently been applied in selected cases of TT injury. Evaluation of the results of this treatment was the main aim of this study. [pubfacts.com]

Prognosis

Conservative observation Surgical early presentation (infancy) radial head reduction must have only mild deformity of radial head and capitellum technique: osteotomy of radius annular ligament reconstruction late presentation radial head excision Outcomes: Prognosis [posna.org]

Follow-up Prognosis The prognosis is excellent for a functional ROM of the elbow, forearm, and wrist, particularly in patients Mild ROM restrictions may be present compared with the contralateral side but usually none that would be noted by the patient [orthopaedicclinic.com.sg]

Treatment and prognosis The dislocation needs to be reduced, and sometimes closed reduction is possible. Failing this open reduction will be necessary 1. [radiopaedia.org]

Pathophysiology

A review of the biomechanical studies of the elbow ligaments enables us to propose a pathophysiological model of this injury, and a case report and review of the literature are presented. [ncbi.nlm.nih.gov]

Pathophysiology In the normal elbow, the critical restraint to radial head dislocation is the annular ligament. This ligament usually is torn or severely stretched in the case of a dislocation. [orthopaedicclinic.com.sg]

There is no support for the common assumption that a relatively small head of the radius as compared to the neck of the radius predisposes the young to this injury. [ citation needed ] Pathophysiology [ edit ] The distal attachment of the annular ligament [en.wikipedia.org]

Prevention

Closed reduction was not stable, and open reduction revealed the biceps tendon displaced posteriorly and laterally from the radial tubercle around the radial neck, which prevented stable reduction of the anteromedial dislocation of the radial head. [ncbi.nlm.nih.gov]

In individuals with pronator teres contractures, prophylactic surgical release can be performed to prevent dislocation 1 . [radiopaedia.org]

Its purpose is to prevent movement of the arm at the elbow. Usually, the arm will be placed in a sling to help the patient hold the splint in a level position and to prevent pressure on the elbow joint. [emedicinehealth.com]

Additionally, the sutures cannot prevent the growth of radial head since they are absorbable [ 25 ]. [bmcmusculoskeletdisord.biomedcentral.com]

The situation is rare in adults, or in older children, because the changing shape of the radius associated with growth prevents it. [en.wikipedia.org]
