Radial Head Dislocation

Dislocation of the Radial Head

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]

  • Asymptomatic

    After a follow-up of 18 months, the child remained asymptomatic and regained a full range of motion. Radiographic study revealed satisfactory reduction of the radial head with no recurrence of the osteochondroma. [ncbi.nlm.nih.gov]

    Congenital Radial Head Dislocation Follow-up Care Asymptomatic patients can be as active in sports as their function allows. May consider limiting contact sports. [eorif.com]

    Although it can initially be asymptomatic, pain, restriction of movement and secondary arthritic changes may develop as the child grows [ 1, 2, 3, 4 ]. The treatment of chronic radial head dislocation remains controversial. [em-consulte.com]

    Although it is most often bilateral, unilateral congenital radial head dislocation has been described. 6 Physical Examination Congenital dislocation of the radial head is typically discovered incidentally because it is most frequently an asymptomatic [healio.com]

    These dislocations may be of either congenital or traumatic origin. [83] Although they might be initially asymptomatic, arthritic changes may restrict movement as time goes on. [84] Long-term dislocations often result in valgus deformity of the elbow, [emedicine.medscape.com]

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

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]

What Is the Prognosis for a Dislocated Elbow? Generally, this injury heals well and has a good prognosis. [emedicinehealth.com]

On the basis of the previously published data of 14 cases and our data, we have summarized the etiology, clinical features, natural history, and treatment of FFCD in the ulna. [ncbi.nlm.nih.gov]

Classification: Direction of radial head displacement: Anterior, posterior, or lateral Pathogenesis: Traumatic, congenital, or pathologic Epidemiology Radial head dislocations are uncommon injuries, usually occurring with an associated ulna fracture. [orthopaedicclinic.com.sg]

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]

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]

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

The child’s compensatory shoulder and wrist motion usually prevents functional limitations and parental awareness until direct observation and inspection occurs. This is similar to the presentation of radioulnar synostosis (see Chapter 17 ). [musculoskeletalkey.com]

Long standing dislocations may prevent good results due to dysplastic changes of both the radial head and the capitellum [ 4, 8 ]. [em-consulte.com]
