Increased Acetabular Depth May Influence Physeal Stability in Slipped Capital Femoral Epiphysis

David A. Podeszwa MD, David Gurd MD, Anthony Riccio MD, Adriana Rocha MS, Daniel J. Sucato MD, MS

Multiple mechanical factors affecting the hip have been associated with the development of slipped capital femoral epiphysis (SCFE). Whether acetabular depth plays a role in the development of a SCFE has not been elucidated.

Skin Crease ‘Bikini’ Incision for Anterior Approach Total Hip Arthroplasty: Surgical Technique and Preliminary Results

Michael Leunig MD, Michael Faas MD, Fabian Knoch MD, Florian D. Naal MD

The direct anterior approach for THA allows implantation through an internervous plane without muscle detachment from bone. However, the classic longitudinal skin incision does not follow the anatomic skin creases and can result in scar widening. We therefore modified our incision technique to a short oblique skin incision following the anatomic skin crease of the groin.

A Positive Hip Arthrogram May Predict Lower Function in Patients with Primary Hip Arthroplasty

Jason B. T. Lim MBChB (Hons), Lynne Horey MA, Sanjeev Patil FRCS (Tr & Orth), Robert M. D. Meek MD, FRCS (Tr & Orth)

A local anesthetic hip arthrogram is a simple test mainly used as an adjunct to define the origin of hip pain. Temporary pain relief (a positive response) following an injection may lead to a surgeon recommending hip surgery. However, it is unclear whether relief of pain corresponds to better postoperative pain relief or function.

Heterotopic Bone Formation About the Hip Undergoes Endochondral Ossification: A Rabbit Model

Oliver Tannous MD, Alec C. Stall MD, Cullen Griffith MD, Christopher T. Donaldson MD, Rudolph J. Castellani MD, Vincent D. Pellegrini MD

Heterotopic ossification (HO) occurs most commonly after trauma and surgery about the hip and may compromise subsequent function. Currently available animal models describing the cellular progression of HO are based on exogenous osteogenic induction agents and may not reflect the processes following trauma.

Impingement Adversely Affects 10-year Survivorship After Periacetabular Osteotomy for DDH

Christoph E. Albers MD, Simon D. Steppacher MD, Reinhold Ganz MD, Moritz Tannast MD, Klaus A. Siebenrock MD

Although periacetabular osteotomy (PAO) for developmental dysplasia of the hip (DDH) provides conceptual advantages compared with other osteotomies and reportedly is associated with joint survivorship of 60% at 20 years, the beneficial effect of proper acetabular reorientation with concomitant arthrotomy and creation of femoral head-neck offset on 10-year hip survivorship remains unclear.

Wear of a 5 Megarad Cross-linked Polyethylene Liner: A 6-year RSA Study

Stuart A. Callary BAppSc, David G. Campbell BMBS, FRACS, PhD, Graham Mercer BMBS, FRACS, Kjell G. Nilsson MD, PhD, FRACS, John R. Field MSc, BVSc, DVSc, PhD

One cross-linked polyethylene (XLPE) liner is manufactured using a lower dose of radiation, 5 Mrad, which may result in less cross-linking. The reported in vivo wear rate of this XLPE liner in patients undergoing THA has varied, and has included some patients in each reported cohort who had greater than 0.1 mm/year of wear, which is an historical threshold for osteolysis. Previous studies have measured wear on plain radiographs, an approach that has limited sensitivity.

Do Professional Athletes Perform Better Than Recreational Athletes After Arthroscopy for Femoroacetabular Impingement?

Ajay Malviya FRCS (Tr & Orth), Christos P. Paliobeis MD, Richard N. Villar BSc, MA, MS

Although a large number of athletes’ returns to sports after hip arthroscopic surgery for femoroacetabular impingement (FAI), it is not clear if they do so to the preinjury level and whether professional athletes (PA) are more likely to return to the preinjury level compared with recreational athletes (RA).

Fee-based Care is Important for Access to Prompt Treatment of Hip Fractures Among Veterans

Kelly K. Richardson PhD, Peter Cram MD, Mary Vaughan-Sarrazin PhD, Peter J. Kaboli MD, MS

Hip fracture is a medical emergency for which delayed treatment increases risk of disability and death. In emergencies, veterans without access to a Veterans Administration (VA) hospital may be admitted to non-VA hospitals under fee-based (NVA-FB) care paid by the VA. The affect of NVA-FB care for treatment and outcomes of hip fractures is unknown.

Vascularized Fibular Grafts for Avascular Necrosis After Slipped Capital Femoral Epiphysis: Is Hip Preservation Possible?

Todd Bertrand MD, James R. Urbaniak MD, Robert K. Lark MD, MS

Avascular necrosis (AVN) of the femoral head is a potential complication in patients with slipped capital femoral epiphysis (SCFE), radiographically occurring in 3–60%. This may lead to early hip fusion or hip arthroplasty. Free vascularized fibular grafting (FVFG) may provide a reasonable means to preserve the femoral head.

Severe Metal-induced Osteolysis Many Years After Unipolar Hip Endoprosthesis

Matthew A. Mann MD, Dylan Tanzer DEC, Michael Tanzer MD

Modularity of the femoral head-neck junction provides increased intraoperative flexibility to the surgeon. Complications of this modularity include damage to the trunnion, with subsequent bone and/or soft tissue loss from adverse reactions to metal debris.
