Neglected traumatic hip dislocation: Influence of the increased intracapsular pressure

Abstract

AIMTo investigate that the increased intracapsular pressure, during the delay period, can interrupt the blood flow to the femoral head.METHODSAn observational retrospective study included a group of 17 patients with traumatic hip dislocation, their ages at time of injury averaged 26 (range from 3 to 70) years. Outcomes were assessed clinically and radiographically at a period averaged 11.5 (range from 4 to 20) years.RESULTSMinor trauma caused dislocation in seven and severe trauma in ten patients. All dislocations were posterior, six isolated dislocation and 11 were associated with other injuries. The negligence period averaged 2.5 (ranged from 1 to 4) d. At the latest visit, the radiography revealed normal hip in 11 and avascular necrosis (AVN) in six patients. Clinically, eight patients were rated as excellent, three good, three fair and three poor.CONCLUSIONWe believe the factors that contribute to increased intracapsular pressure also increase the influence of delayed reduction toward the development of AVN.

Outcome of surgically treated acetabular fractures: risk factors for postoperative complications and for early conversion to total hip arthroplasty

“…In our cohort, we collected 60% late complications. Despite a prompt closed reduction (within 6 hours), 6% of our patients suffered from AVNFH, in line with the incidence reported in the literature (3-11%) [1,17,34]. In our analysis, AVNFH development was signi cantly related to the presence of PHD (P=0.004).…”

Clinical Outcomes and Associated Pathologies Following Pediatric Traumatic Hip Dislocations: A Systematic Review of the Literature

“…A total of 24 articles met final inclusion criteria from a total of 219 articles retrieved from the initial search 1–8,12,14–16,18–29 . A total of 12 articles were found from the initial search with an additional 12 articles being included by searching the references of the initial 12 included articles.…”

“…The incidence of traumatic hip dislocations in pediatric patients is estimated to be 0.8 cases per one million children 5 . Despite the rarity of pediatric traumatic hip dislocations, associated injuries (AIs) and long-term adverse events (LTAEs), collectively termed associated pathologies (APs) in this manuscript, frequently concomitant with traumatic hip dislocations in children and adolescents can be devastating and have long-lasting consequences 6,7 . Contrary to adult traumatic hip dislocations, traumatic hip dislocations in children can occur due to relatively minor trauma 2,3,8 .…”

“…Contrary to adult traumatic hip dislocations, traumatic hip dislocations in children can occur due to relatively minor trauma 2,3,8 . The low-energy causes of AIs of pediatric traumatic hip dislocations can cause the initial diagnosis and subsequent treatment to be delayed, possibly exacerbating LTAEs and poor patient outcomes 7 …”
