Effectiveness of prophylactic double-looped wiring in cementless Hip arthroplasty: A biomechanical study in osteoporotic bone model using impaction simulation system.

Background: Periprosthetic femoral fracture (PFF) is well-known complication in cementless hip arthroplasty (HA), especially in the elderly with osteoporosis. To prevent intraoperative PFFs during HA, prophylactic cerclage wiring on the calcar area during femoral broaching and implant insertion is recommended. However, biomechanical data on the benefits of cerclage wiring in osteoporotic bone during impaction are limited and controversial.

Effectiveness of Extracorporeal Shockwave Therapy in the Treatment of Chronic Insertional Achilles Tendinopathy.

Background: Extracorporeal shockwave therapy (ESWT) has been proposed as a conservative treatment for insertional Achilles tendinopathy from limited evidence without placebo controls. Our objective was to assess the effectiveness of ESWT compared with sham controls in chronic insertional Achilles tendinopathy.

Methods: A double-blind, randomized sham-controlled trial was conducted between 2016 and 2018.
