Suggestion for new 4.4 mm pubo-femoral distance cut-off value for hip instability in lateral position during DDH screening.

Acta Orthop 2018 Dec 10:1-8. Epub 2018 Dec 10.

a Department of Children's Orthopaedics , Aarhus University Hospital , Aarhus.

Background and purpose - Current selective screening algorithms for developmental dysplasia of the hip (DDH) are insufficient. Universal screening programs have been proposed but so far have been deemed too expensive and time consuming. The pubo-femoral distance may solve this problem as a quick, low-cost, highly sensitive, and specific sonographic measurement for DDH, but this has only been validated in the supine position.

F-FDG-PET uptake in non-infected total hip prostheses.

Acta Orthop 2018 Dec 18;89(6):634-639. Epub 2018 Oct 18.

c Department of Medical Microbiology and Infection Prevention , University of Groningen, University Medical Center Groningen , Groningen , the Netherlands.

Background and purpose - F-fluorodeoxyglucose positron emission tomography (FDG-PET) can be used in the diagnostic work-up of a patient with suspected periprosthetic joint infection (PJI) but, due to a lack of accurate interpretation criteria, this technique is not routinely applied. Since the physiological uptake pattern of FDG around a joint prosthesis is not fully elucidated, we determined the physiological FDG uptake in non-infected total hip prostheses. Patients and methods - Patients treated with primary total hip arthroplasty (1995-2016) who underwent a FDG-PET/CT for an indication other than a suspected PJI were retrospectively evaluated.

Pelvic obliquity and measurement of hip displacement in children with cerebral palsy.

Acta Orthop 2018 Dec 17;89(6):652-655. Epub 2018 Oct 17.

a Department of Clinical Sciences , Lund University , Lund.

Background and purpose - Pelvic obliquity, common in individuals with cerebral palsy (CP), changes the muscle force vector on the hip joint and probably affects the risk of hip dislocation. We evaluated a new method for measurement of hip displacement in CP that takes the pelvic obliquity into account: the pelvic adjusted migration percentage (PAMP). Children and methods - From the Swedish surveillance program for cerebral palsy (CPUP), the first pelvic radiograph of 268 children <18 years in southern Sweden during a 3-year period were evaluated.

Time-driven activity-based cost of outpatient total hip and knee arthroplasty in different set-ups.

Acta Orthop 2018 Oct 6;89(5):515-521. Epub 2018 Aug 6.

a Department of Orthopedic Surgery , Copenhagen University Hospital Hvidovre , Copenhagen.

Background and purpose - Length of stay (LOS) following total hip and knee arthroplasty (THA and TKA) has been reduced over the years due to fast-track. Short stays of 2 days in fast-track departments in Denmark have resulted in low total costs of around US$2,550. Outpatient THA and TKA is gaining popularity, albeit in a limited and selected group of patients; however, the financial benefit of outpatient arthroplasty remains unknown. Read More
