“…Patients with PLRI complain about locking and clicking of the elbow, particularly when the elbow is supinated and extended. This pattern of instability can be demonstrated by the so-called pivot-shift test for posterolateral rotatory instability (OʼDriscoll et al 1991) (Figure 2). In case of doubt, evaluation under anesthesia in combination with arthroscopy can be performed.…”

“…On lateral radiographs, the radial head may appear to be situated poste- riorly to the capitellum, especially in full supination (Figure 3). MRI and CT are of no use in the evaluation of integrity of LUCL (OʼDriscoll et al 1991). MRI can be useful for detection of chondral damage to the capitellum secondary to the recurrent subluxation of the radial head (Peiss 1995).…”

“…During posterolateral dislocation, rupture of the ligamentous complex occurs in a circle from lateral to medial, as described by OʼDriscoll et al In stage I, the LUCL is disrupted; in stage II, the other lateral ligamentous structures as well as the anterior and posterior capsule are disrupted; In stage III, rupture of the MCL occurs. Rupture of the MCL can be partial or complete (OʼDriscoll et al 1991).…”

Operative Stabilisierung dieser potentiell verheerenden Verletzung, um frühzeitige Bewegungen des Ellenbogengelenks ohne neuerliche Instabilität zu erlauben und damit ein gutes funktionelles Ergebnis zu erzielen. IndikationenInstabile Luxationsfrakturen des Ellenbogengelenks. Verbliebene humeroulnare oder humeroradiale Instabilitäten nach geschlossener Reposition. Gelenkblockaden durch Fragmente. Instabilitäten nach begonnener Bewegungstherapie. KontraindikationenStabil reponiertes Ellenbogengelenk mit minimal dislozierten Frakturen des Radiuskopfs und Processus coronoideus ohne Gelenkblockaden. OperationstechnikWiederherstellung der Stabilität des Radiuskopfs, des Processus coronoideus und der ligamentären Strukturen über verschiedene Zugänge und Maßnahmen. Anlage eines Bewegungsfixateurs in Fällen, in denen durch die operativen Maßnahmen keine ausreichende Stabilität des Ellenbogens für eine frühe funktionelle Nachbehandlung erreicht werden kann, und nach Revisionseingriffen. ErgebnisseEine normale Ellenbogenfunktion darf nach dem Verletzungsmuster einer "terrible triad" nicht erwartet werden. Bei optimaler Therapie kann mit einem stabilen, gering schmerzhaften Ellenbogen gerechnet werden, dessen durchschnittliches Bewegungsausmaß bei Streckung 20°, bei Beugung 135° und bei Vorderarmdrehung 135° beträgt. Nach einem durchschnittlichen Nachuntersuchungszeitraum von 31 Monaten zeigten 80% der 41 Patienten (Durchschnittsalter 42 Jahre) dieser Serie ein sehr gutes oder gutes Ergebnis nach dem Mayo Elbow Performance Index. Abstract ObjectiveThe primary goal is the surgical stabilization of this potentially devastating injury to permit early motion without fear of provoking recurrent instability. This enhances range of motion and functional outcome.

s a unit, the four joints of the elbow provide increased mobility for the hand and wrist. ,This unit also provides stalilitv t o lie proximal upper extremity to allow for skilled o r forceful movements of the hand. These functions are reflected in the elbow's unique anatomy and structure. ARTHROLOGY OF THE ELBOW COMPLEXT h e elbow joint complex, illustrated in Figure 1, is composed of the humeroulnar, radioulnar, and superior and inferior radioulnar articulations. T h e superior and inferior radioulnar joints function essentially as one joint, although only the superior radioulnar joint has a direct association with other elbow coniplex counterparts. T h e elbow proper and the superior radioulnar joint are enclosed by a single joint capsule. Humeroulnar JointT h e humeroulnar joint is a uniaxial, diarthrodial joint, with 1 degree of freedom, flexion, and extension. Although generally described as a hinge joint, the humeroulnar joint is probably more appropriatelv designated a modified hinge joint, with small amounts (approximately 5") of internal and external rotation occurring at the extremes of flexion and extension (26).
