loss of structural integrity, collapse, and subchondral failure.3,4 In this chapter, we discuss the different etiologies of ONFH, diagnosis and classification systems, nonoperative management, indications for total hip arthroplasty (THA) in the setting of ONFH, and explore perioperative considerations in treating patients with ONFH while taking into account special

early menopause accelerating bone loss in females due to cessation of ovarian estrogen production.22 Tobacco’s effects on parathyroid hormone (PTH) are mixed. Tobacco has been found in some cases to decrease PTH secretion, which in turn decreases conversion of 25-hydroxy vitamin D to the active form

early mobilization.53 Clinical pathways are usually specific to the procedure and hospital facility and are carried out by specialized care teams to produce optimal patient-centered results.58 A Mayo Clinic “before and after” clinical pathway implementation study demonstrated that the use of a clinical pathway was associated with improved outcomes

loss compared with THA done without prior PAO, but no differences in complication rates, clinical outcomes, or survivorship have been found.56 Conclusions DDH is a known cause of prearthritic hip pain, hip dysfunction, and secondary OA, which often presents at an early age and is more common in females. High

pregnancy and vaginal delivery. • Fig. 23.1Sexual dimorphism in the human pelvis. In relation to the average male pelvic morphology the female pelvis has (A) a more circular pelvic inlet with a longer superior pubic ramus, (B) a wider and shallower greater sciatic notch and a more horizontally oriented sacrum

Early mobilization has been shown to reduce length of stay.2 Nowadays, at outpatient surgery centers, postoperative rehabilitation begins in the PACU with physical therapy (PT) evaluation and mobilization with an assistive device, usually a walker. In the absence of any intraoperative complications affecting implant stability, patients may be weight-bearing
