Hip Int 2019 Feb 5:1120700019826482. Epub 2019 Feb 5.

1 Cleveland Clinic, Department of Orthopedic Surgery, Cleveland, Ohio, USA.

Background:: Evaluating body mass index (BMI) as a continuous variable eliminates the potential pitfalls of only considering BMI as a binary or categorical variable, as most studies do when correlating BMI and total hip arthroplasty (THA) outcomes. Therefore, the objective of this study was to correlate the effect of continuous BMI on 30-day complications post-THA. Specifically, we correlated BMI to: (1) 30-day readmissions and reoperations; (2) medical complications; and (3) surgical complications in: (a) normal-weight; (b) over-weight; (c) obese; and (d) morbidly obese patients.

Higher offset cross-linked polyethylene acetabular liners: is wear a significant clinical concern?

Hip Int 2018 Dec 7:1120700018815339. Epub 2018 Dec 7.

2 Towson Orthopaedic Associates, Towson, MD, USA.

Introduction:: Total hip arthroplasty (THA) is the 2nd most common total joint replacement surgery in the United States. However, not all THA devices perform well and need revised for several reasons including dislocation. Higher offset acetabular liners reduce this problem by creating a more anatomically/biomechanically natural hip joint, increasing soft-tissue tension, and accommodating larger femoral heads in smaller acetabular cups via increased polyethylene thickness.

Statin use is associated with less postoperative cardiac arrhythmia after total hip arthroplasty.

Hip Int 2018 Dec 10:1120700018816091. Epub 2018 Dec 10.

Department of Orthopaedic Surgery, Stanford University, Redwood City, CA, USA.

Introduction:: While statins have been found to reduce postoperative atrial fibrillation after cardiac surgery, little is known about their use in total hip arthroplasty (THA). This study investigated if statins would similarly reduce postoperative arrhythmias in patients undergoing THA.

Methods:: We queried a large Medicare and private-payer database from 2005 to 2012 and identified 12,075 patients who were on a statin prior to THA. Read More

Is a cementless fixation of the femoral component suitable for metal-on-metal hip resurfacing arthroplasty?

Hip Int 2018 Nov 26:1120700018815055. Epub 2018 Nov 26.

The Joint Replacement Institute at St Vincent Medical Center, Los Angeles, CA, USA.

Background:: Hip resurfacing arthroplasty (HRA) typically uses a hybrid design (cemented femoral component and cementless acetabular shell) but has recently been performed with fully cementless components. There is a paucity of information on the clinical performance of these cementless designs.

Methods:: The UCLA clinical scores, SF-12 quality of life scores, complication rates, survivorship and radiographic signs of loosening or gross stress shielding of 39 hips (39 male patients) implanted with cementless HRA were compared with those of 40 hips (37 male patients) implanted with hybrid HRA during the same time frame.

Posterior "Open Book" approach for type 1 internal hemipelvectomy.

Hip Int 2018 Nov 22:1120700018812415. Epub 2018 Nov 22.

1 Hansjörg Wyss Department of Plastic Surgery, NYU Langone Health, New York, NY, USA.

Introduction:: Internal limb-sparing hemipelvectomy is currently the preferred surgical option for resection of pelvic tumours. Obtaining an acceptable functional outcome through the standard ilioinguinal or iliofemoral incisions, only compounds the already challenging dissection, resection and reconstruction of these extensive en-bloc extirpative oncologic operations.

Surgical Technique:: We describe a novel surgical approach to the lateral pelvis that minimises injury to the gluteal muscles, spares the gluteal vessels and provides a broad yet shallow operative field conducive to microsurgery with sizeable vasculature in close proximity to facilitate any microsurgical reconstruction.

The use of silver coating in hip megaprostheses: a systematic review.

Hip Int 2019 Jan 16;29(1):7-20. Epub 2018 Nov 16.

4 National Institute for Health Research Bristol Biomedical Research Centre, Bristol, UK.

Retrospective studies of silver-coated hip implants have demonstrated promising results and safety profile, however, the potential benefits are so far unproven in prospective studies. Silver-coated implants may have a role in patients undergoing revision or primary surgery with a high risk of infection but as yet there are no human studies investigating silver in primary hip arthroplasty. Adequately powered robust prospective studies are needed in this area to determine if silver-coated implants would be efficacious and cost-effective. Read More
