Accuracy of Ultrasound-Guided Intra-articular Hip Injections Performed in the Orthopedic Clinic.
Intra-articular hip injections have proven clinical value for both diagnostic and therapeutic purposes. Historically, these injections have been performed by radiologists using fluoroscopic guidance. This necessitates a radiology referral, delays the injection, and represents lost productivity for the orthopedist. ⋯ Revenue value units ranged from 1.72-2.55 for ultrasound-guided hip injections. These findings indicate ultrasound-guided intra-articular hip injections performed in the orthopedic clinic by surgeons or physician assistants are accurate, efficient, and patient-friendly. Additionally, they preserve patient continuity and maintain productivity within the orthopedic clinic. [Orthopedics. 2017; 40(2):96-100.].

The cement-in-cement technique is useful in the setting of revision total hip arthroplasty (THA), especially to gain acetabular exposure, change a damaged or loose femoral component, or change the version, offset, or length of a fixed femoral component. The goal of this retrospective study was to assess the clinical and radiographic characteristics of revision THA using the cement-in- cement technique. Between 1971 and 2013, a total of 63 revision THAs used an Omnifit (Osteonics, Mahwah, New Jersey) or Exeter (Howmedica, Mahwah, New Jersey) stem and the cement-in-cement technique at the senior author's institution. ⋯ Eleven (18%) cases required revision THA, but only 1 (2%) revision THA was for aseptic removal of the femoral component. All other femoral implants had no evidence of component migration, cement mantel fracture, or circumferential lucent lines at final follow-up. The patients who underwent cement-in-cement revision THA at the senior author's institution had good restoration of function but a high complication rate. [Orthopedics. 2017; 40(2):e348-e351.].
