Posterolateral rotatory instability of the elbow.
Since its original description by O'Driscoll in 1991, PLRI is becoming increasingly recognized as a significant cause of elbow pathology. It is well documented that this problem results from an insufficiency of the radial ulnohumeral ligament and its related lateral structures, and that this insufficiency is usually the result of elbow trauma. Diagnosis has improved with the introduction of the...
متن کاملASPECTS OF CURRENT MANAGEMENT Posterolateral rotatory instability of the elbow
J Bone Joint Surg [Br] 2008;90-B:272-9. Posterolateral rotatory instability is the most common type of symptomatic chronic instability of the elbow. In this condition the forearm complex rotates externally in relation to the humerus, causing posterior subluxation or dislocation of the radial head. The lateral ligament complex, radial head and coronoid process are important constraints to poster...
متن کاملLigamentous repair and reconstruction for posterolateral rotatory instability of the elbow.
We describe the intermediate results of lateral ligamentous repair or reconstruction for posterolateral rotatory instability of the elbow. Between 1986 and 1999, we performed 12 direct repairs and 33 ligament reconstructions with a tendon autograft. One patient was lost to follow-up and 44 were retrospectively studied at a mean of six years (2 to 15). Surgery restored stability in all except fi...
متن کاملPosterolateral rotatory instability of the elbow in association with lateral epicondylitis. A report of three cases.
ateral stability of the elbow depends on the integrity of the lateral collateral ligament and secondary softtissue restraints. Posterolateral rotatory subluxation of the elbow has been recognized in association with elbow trauma, surgery for epicondylitis, and congenital cubitus varus deformity. While abnormal signal changes on magnetic resonance imaging have been shown to include the lateral c...
متن کاملLong-term sequel of posterolateral rotatory instability of the elbow: a case report
The natural course of untreated posterior lateral rotatory instability of the elbow is unclear. A case of elbow arthrosis with progressing deformity and flexion contracture after an episode of elbow dislocation about 20 years ago presented the possibility the long term outcome of untreated posterior lateral rotatory instability of the elbow.
