Traumatic hip dislocation in childhood.

Eighteen cases of traumatic dislocations of the hip in children under 15 years of age presenting between 1985 and 1995 were reviewed. Fifteen of the dislocations were posterior. There were two groups: a younger group dislocating with minimal trauma and an older group whose injuries involved significantly more trauma. All patients were treated by closed reduction, but two required open reduction because of intraarticular fragments preventing a full reduction. On long-term follow-up of the 16 available patients (average length of follow-up, 5 years 10 months; range, 17-132), there were no cases of avascular necrosis or early degenerative change.

A vascular necrosis following traumatic hip dislocation in childhood: factors of influence.

An evaluation was made of the factors possibly influencing the incidence of vascular necrosis in a collected series of 412 traumatic hip dislocations in children. This series consisted of 145 cases with necrosis, and 267 dislocations in which this complication had not developed after a follow-up period of 2 years or more. The age of the patient, the severity of the injury, the type of dislocation and the interval before reduction proved to be influencing factors. The reduction procedure appeared to play a similar role, but this could not be definitely assessed. The post-reduction immobilization and the interval before weight-bearing had no influence. Therapeutic principles are indicated.

Congenital contractures, short stature, abnormal face, microcephaly, scoliosis, hip dislocation, and severe psychomotor retardation in two unrelated girls. a new MCA/MR syndrome?

Severe mental retardation, congenital contractures, short stature, microcephaly, ptosis, myopia, beaked nose, abnormal teeth, hip dislocation, and severe scoliosis, are described in a 16-year-old and an unrelated 24-year-old females. Results of all laboratory investigations were normal. Review of the literature, of the London Dysmorphology Data Base and POSSUM did not yield to any diagnosis. Whether these patients present a new MCA/MR syndrome is discussed.

[Morphology of a pelvitrochanteric nearthrosis in proximal hip dislocation].

A joint between the pelvis and the minor trochanter on the right hip of a 87 year old female will be investigated. The investigation includes the joint between the femoral head and the secondary socket. An analyse of the cartilage and the cancellous bone structure shows, that the joint pressure will be transmitted not only by the hip joint but also by the new joint.

Right upper limb bud triplication and polythelia, left sided hemihypertrophy and congenital hip dislocation, facial dysmorphism, congenital heart disease, and scoliosis: disorganisation-like spectrum or patterning gene defect?

A Somali female baby with right upper limb triplication, polythelia, left sided hemihypertrophy, congenital hip dislocation, facial dysmorphism, congenital heart disease, and scoliosis is described. It seems that the above described pattern of anomalies has not been reported before. The possible developmental genetic mechanism responsible for this phenotype is briefly discussed.

Subcapital fracture of a congenitally dislocated hip: revival of Girdlestone resection arthroplasty.

A twenty-year-old, active male with a high congenital dislocation of the hip sustained a displaced subcapital fracture (accompanied by a comminuted transarticular fracture of the ipsilateral distal femur). Such a combination of injuries poses a challenging problem; the English literature does not cite any report describing the occurrence of subcapital fractures in congenitally dislocated hips. This article reviews the treatment options of the fractured neck of the femur, and the reasons for electing to perform a Girdlestone resection arthroplasty.

Development and Physical Validation of a Finite Element Model of Total Hip Dislocation.

Component-on-component impingement, followed by levering of the femoral head, is a common mode of dislocation in total hip arthroplasty. While there have been many registry-based studies of dislocation incidence, confounding factors and sources of variability in the clinical domain make it difficult to identify specific parameter influences. A three dimensional nonlinear finite element model has been developed for the purpose of studying the dislocation event, to allow determination of how individual factors such as component design and clinical implantation position affect the propensity for dislocation. Also, a laboratory testing apparatus was constructed to provide physical validation of the computational model. The finite element model correctly predicted the range of motion observed in the physical apparatus to within 1%, and predicted the peak resisting moment to within 2.5%. Under even a light joint load of 200 N, the von Mises stresses developed in the polyethylene insert reached 13 MPa, and the contact stresses rose to as high as 30 MPa. These deleterious elevations occurred not only at the site of neck impingement, but also at the site of head egress from the liner.

Arthroscopy of a dislocated hip replacement: a case report.

A 55-year-old woman had a dislocation of a total hip arthroplasty that could not be reduced by closed manipulation because of an obstructing cement fragment. The use of percutaneous arthroscopic instrumentation allowed reduction by successful manipulation of the fragment out of the joint.
