Preoperative Risk Factors for, and Incidence of Delayed Surgery in Elective Primary Total Knee Arthroplasty After Hospital Admission: The ACS-NSQIP.

Background: Approximately 600,000 total knee arthroplasties (TKA) are performed every year in the United States and the number of procedures has increased substantially every year. These demands may further strain the government, insurers, and patients struggling with increasing healthcare spending. A delay in proceeding to surgery after hospital admission may affect the overall healthcare costs.

Stress fractures in the elderly: different pathogenetic features compared with young patients.

Stress fractures mainly occur in the lower limb as a result of cyclic submaximal stresses. Most commonly affected by this specific type of fractures are young athletes, military or elderly subjects with metabolic bone diseases like osteoporosis. In consideration of the heterogeneity of affected patients is presumable that there are different pathogenic mechanisms.

Free-style perforator flaps in the reconstruction of the lower limb.

Introduction: The evolving concept of free-style flaps with one or more perforators able to lend support, has been shown to have noteworthy advantages in the context of reconstructive surgery, especially in relation to the distal portion of the lower limb. Among the advantages, an analogy of the covering tissues with pre-existing ones in the compromised area, reduced morbidity of the donor site, less time spent in theatre and a greater flexibility from the surgeons' point of view.

Material And Methods: Between 2009 and 2012, 18 patients were treated with local free-style flaps for lesions involving the leg and the foot.
