Anterior hip dislocation in conjunction with a stroke: a diagnosis not to miss

Abstract

Anterior dislocation of the native hip joint is an uncommon presentation accounting for around 15% of all hip dislocations. It is usually the result of a high-energy impact in circumstances such as a motor vehicle accident or a fall from a significant height. A delay in relocation of more than 6 h has been associated with a high risk of avascular necrosis of the femoral head. We report the case of a 75-year-old man who suffered an anterior dislocation of his native hip following a fall from a standing height, associated with an acute cerebrovascular stroke. There was significant delay in the recognition of the dislocation due to the coexistent signs of the stroke. This case illustrates that hip dislocation can occur following a low-energy mechanism of injury with the possibility of serious long-term consequences if it is not promptly recognised and treated.

Bilateral anterior dislocation in the hips: a case report

“…Anterior dislocation of the native hip is the least prevalent type of dislocation and accounts for approximately 8% to 15% of total hip dislocations [6]. Bilateral anterior dislocations comprise fewer than 1% of all hip dislocations.…”

Low trauma posterior native hip dislocation with acute longitudinal transverse myelitis due to SARS-CoV-2 - A case-report

“…There have been case reports on anterior native hip dislocation secondary to stroke [ 2 ], hip dislocation in spinal muscular atrophy [ 8 ] and many studies showing increased incidence of THR dislocation in patients with neurological condition like Parkinson's disease.…”

“…Although hip subluxation and dislocation occur commonly in neuromuscular diseases such as cerebral palsy, spinal muscular atrophy and myelomeningocele, they are not known to affect patients with transverse myelitis. There have been case reports on anterior native hip dislocation secondary to stroke [ 2 ] and many studies show increased incidence of Total Hip Replacement dislocation in patients with neurological condition like Parkinson's disease. We present an unusual case of posterior hip dislocation from a trivial fall from standing height in a patient that, after investigations, was found to have acute longitudinal transverse myelitis and SARS-CoV-2.…”
