Effect of Prior Salter or Chiari Osteotomy on THA with Developmental Hip Dysplasia

Kenji Tokunaga MD, Nadim Aslam MD, FRCSC, Rad Zdero PhD, Emil H. Schemitsch MD, FRCSC, James P. Waddell MD, FRCSC

Controversy exists regarding the outcome of THA after prior pelvic osteotomy.

Cams and Pincer Impingement Are Distinct, Not Mixed: The Acetabular Pathomorphology of Femoroacetabular Impingement

Justin Cobb MCh, Kartik Logishetty BSc, Kinner Davda MRCS, Farhad Iranpour MD

Many impinging hips are said to have a mix of features of femoral cam and an overcovered acetabulum causing pincer impingement. Correction of such a mixed picture by reduction of the cam lesion and the acetabular rim is the suggested treatment.

Minimally Invasive versus Classic Procedures in Total Hip Arthroplasty: A Double-blind Randomized Controlled Trial

Jon H. M. Goosen MD, PhD, Boudewijn J. Kollen PhD, René M. Castelein MD, PhD, Bart M. Kuipers MD, Cees C. Verheyen MD, PhD

For total hip arthroplasty (THA), minimally invasive surgery (MIS) uses a smaller incision and less muscle dissection than the classic approach (CLASS), and may lead to faster rehabilitation.

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.
