Femoral Head-neck Junction Deformity is Related to Osteoarthritis of the Hip

Hilton José Melo Barros MD, Gilberto Luis Camanho MD, PhD, Antônio Carlos Bernabé MD, PhD, Marcelo Bordalo Rodrigues MD, Luiz Eugênio Garcez Leme MD, PhD

Primary or idiopathic osteoarthritis (OA) of the hip has increasingly been attributed to the presence of presumably minor femoral or acetabular deformities that are not routinely identified. The alpha angle reflects one such deformity of the femoral neck and reflects a risk for femoroacetabular impingement, which in turn reportedly is associated with OA. If impingement is in fact associated with OA, then one might expect the mean alpha angle to be greater in patients with presumed idiopathic hip OA.

Case Report: Spinal Anesthesia by Mini-laminotomy for a Patient with Ankylosing Spondylitis who was Difficult to Anesthetize

K. H. Leung MRCS, K. Y. Chiu FRCS, Y. W. Wong FRCS, J. C. Lawmin FFARCSI, FHKCA

Orthopaedic surgeons frequently encounter patients with ankylosing spondylitis who would benefit from various types of lower limb operations; however, some of these patients present challenges for anesthesiologists.

Cartilage Thickness in the Hip Measured by MRI and Stereology Before and After Periacetabular Osteotomy

Inger Mechlenburg MSc, PhD, Jens R. Nyengaard MD, DMSc, John Gelineck MD, Kjeld Soballe MD, DMSc, Anders Troelsen MD, PhD

Untreated hip dysplasia can result in a degenerative process joint and secondary osteoarthritis at an early age. While most periacetabular osteotomies (PAOs) are performed to relieve symptoms, the osteotomy is presumed to slow or prevent degeneration unless irreparable damage to the cartilage has already occurred.

Nationwide Epidemiologic Survey of Idiopathic Osteonecrosis of the Femoral Head

Wakaba Fukushima MD, PhD, Mikihiro Fujioka MD, PhD, Toshikazu Kubo MD, PhD, Akiko Tamakoshi MD, PhD, Masaki Nagai MD, PhD, MSc, Yoshio Hirota MD, PhD

Although numerous studies describe the clinical characteristics of idiopathic osteonecrosis of the femoral head (ONFH) in specific study populations, these have not been confirmed in countrywide studies.

Medicine versus Orthopaedic Service for Hospital Management of Hip Fractures

Cynthia H. Chuang MD, MSc, Gregory J. Pinkowsky MD, Christopher S. Hollenbeak PhD, April D. Armstrong MD, MSc, FRCSC

Hospital care of patients with hip fractures often is managed primarily by either a medicine or orthopaedic service, depending on the institution. Whether complication rates, length of stay, or time to surgery differs on different services is unknown.

High Long-term Survival of Bulk Femoral Head Autograft for Acetabular Reconstruction in Cementless THA for Developmental Hip Dysplasia

Mitsunari Kim MD, Toru Kadowaki MD

Deficient acetabula associated with acetabular dysplasia cause difficulty achieving adequate coverage of the acetabular component during THA. Autografting with the removed femoral head has been used for several decades to achieve better coverage, but the long-term benefits of this technique remain controversial, with some series reporting high rates of graft resorption and collapse.

Second-generation Highly Cross-linked X3™ Polyethylene Wear: A Preliminary Radiostereometric Analysis Study

David G. Campbell BM, BS, FRACS, PhD, John R. Field MSc, BVSc, DVSc, PhD, Stuart A. Callary BAppSc

First-generation highly cross-linked polyethylene liners have reduced the incidence of wear particle-induced osteolysis. However, failed acetabular liners have shown evidence of surface cracking, mechanical failure, and oxidative damage. This has led to the development of second-generation highly cross-linked polyethylene, which has improved wear and mechanical properties and resistance to oxidation in vitro. Owing to its recent introduction, there are no publications describing its clinical performance.

Case Report: Neuropathic Arthropathy of the Hip as a Sequela of Undiagnosed Tertiary Syphilis

Nicholas A. Viens MD, Tyler Steven Watters BA, Emily N. Vinson MD, Brian E. Brigman MD, PhD

Neuropathic arthropathy is characterized by rapidly progressive bone destruction in the setting of impaired nociceptive and proprioceptive innervation to the involved joint. It is seen most commonly in the foot and ankle, secondary to peripheral neuropathy in patients with diabetes mellitus. Other less common sites of involvement may include the knee, hip, shoulder, and spine, depending on the underlying etiology. Neuropathic arthropathy can be associated with tabes dorsalis, a unique manifestation of late, tertiary neurosyphilis that may arise in individuals with untreated syphilis many years after initial infection, and usually involves the knee, or less commonly, the hip.

Case Report: Osteonecrosis of the Femoral Head after Hip Arthroscopy

Danielle L. Scher MD, Philip J. Belmont MD, Brett D. Owens MD

Hip arthroscopy is a common orthopaedic procedure used as a diagnostic and therapeutic tool with a multitude of surgical indications. The complication rate is reportedly between 1.3% and 23.3%. Major complications are related to traction, fluid extravasation, and iatrogenic chondral injury. Although osteonecrosis is a concern with any surgical procedure about the hip, this complication has been primarily a theoretical concern with hip arthroscopy.
