Irreducible acute anterior dislocation of the shoulder: interposed bicipital tendon

Irreducible superolateral dislocation of the glenohumeral joint

“…Open surgical reduction is often necessary to address these injuries [6]. Irreducible anterior shoulder dislocation is well documented in the literature [7] and has been attributed to impaction of the humeral head at the glenoid [7,8], as well as interposition of the rotator cuff muscles/tendons [9][10][11][12] or long-head biceps tendon [12][13][14][15] within the joint. Interposition of the long head of the biceps tendon within the glenohumeral joint has also been described with an irreducible 5 Fifty-three-year-old man with a Bsuperolateral^dislocation of the right glenohumeral joint.…”

Pseudo-reduction of an acute anterior dislocation of the shoulder—a case report

“…Irreducible anterior dislocations of the shoulder have been well described (Razemon 1961, Lam 1966, Kuhnen and Groves 1979, Vichard et al 1981, Seradge and Orme 1982, Tietjen 1982, Oni 1983, Bridle and Ferris 1990, Inao et al 1990, Ilahi 1998, Davies et al 2000, Mihata et al 2000, with responsible factors including (1) impaction of the humeral head on the glenoid rim (Herbert 1946), (2) held by a tightly stretched subscapularis (Lam 1966, Kuhnen and Groves 1979, Ilahi 1998, and (3) interposition of a surrounding structure including rotator cuff (Vichard et al 1981, Tietjen 1982, Figure 1. Anterior-posterior view and axillary view, immediately following closed reductio biceps tendon (Cubbins et al 1934, Seradge and Orme 1982, Freeland and Higgins 1985, Inao et al 1990), torn labrum (Seradge and Orme 1982), subscapularis (Bridle and Ferris 1990), a fracture fragment of the greater tuberosity (Oni 1983, Davies et al 2000, or a displaced fragment of the anterior glenoid rim (Mihata et al 2000).…”

Eine Schulterluxation und ihr Repositionshindernis

“…Hierbei zeigten die konventionellen Röntgenaufnahmen der linken Schulter im a. In der Literatur wird nur von wenigen Fäl-len berichtet, in welchen aufgrund einer irreponiblen anterioren Schulterluxation eine offene Reposition erforderlich war [5,9,11,13,14,16,19,21,25]. Die Gründe für eine irreponible Schulterluxation können sowohl in der Interposition von Weichteilgewebe als auch von knöchernen Fragmenten oder einer Kombination von beiden liegen [9].…”

“…Als knöcherne Interpositionsursachen nach einer anterioren Schulterluxation wurden von Inao et al [14], Mihata et al [16] sowie Oni et al [19] und weiteren Autoren [12,15] knöcherne Glenoidfragmente, Tuberculum-majus-Fragmente bzw. ein impaktierter Humeruskopf am ventralen Glenoidrand angegeben.…”
