Bilateral irreducible inferior shoulder dislocation: A case report

Abstract

HighlightsBilateral luxatio erecta is rare.We present a unique case in which the dislocation was irreducible.The outcome was excellent with minimal restriction of abduction.

Irreducible inferior shoulder dislocation requiring open reduction: A case report

“…In this case, we attempted both of these procedures under general anesthesia, but they were ineffective. To date, only two case reports have presented irreducible ISD details [ 4 , 5 ]. Frank et al reported that irreducibility occurred because of direct inhibition from the aberrant (anterior) position of the axillary nerve [ 4 ].…”

“…Frank et al reported that irreducibility occurred because of direct inhibition from the aberrant (anterior) position of the axillary nerve [ 4 ]. Khedr et al stated that humeral head entrapment in a button-hole through the inferior shoulder joint capsule inhibited reduction [ 5 ]. In our case, intraoperative findings revealed that the button-hole entrapment of the humeral head by the inferior capsule caused irreducibility, while the interposition of the axillary nerve was not observed.…”

“…In our case, in addition to the complete rupture of the supraspinatus tendon, the infraspinatus tendon and teres minor tendon were detached from the humeral head. Since a massive RCT or greater tuberosity fracture was also involved concurrently in those reported cases requiring open reductions [ 4 , 5 ], the failure of the forced couple caused by such a RCT or greater tuberosity fracture can be ascertained as one of the factors contributing to the irreducibility of ISD.…”

“…In the two-step maneuver process, inferior dislocation is converted to anterior dislocation and the upper limb is then pulled and rotated [ 3 ]. Although these closed reduction procedures were effective to achieve reduction previously [ 2 , 3 ], for the rarely occurring irreducible ISD, only two cases requiring open reduction have been reported until now [ 4 , 5 ]. Moreover, the factors that affect closed reduction failure for ISD are not fully understood.…”

Unusual presentation of bilateral inferior shoulder dislocation following a trivial fall in an elderly female: a case report

“…The inferior dislocations known as luxatio erecta are infrequent constituting only 0.5% of all shoulder dislocations 2 . However, bilateral inferior dislocation of the shoulder joint is rare 3 . These usually result following significant impact from forceful hyperabduction or direct axial loading in the abducted position.…”
