ABSTRACT
Aseptic necrosis of lunate bone (Kienb(o)ck's disease) is a comnon cause of wrist pain in clinic.After more than a century of research,although progress has been made in the etiology,pathogenesis and clinical treatment of lunar bone aseptic necrosis,its pathogenesis remains unclear.At present,it is generally believed that the blood supply destruction of lunar bone due to trauma is one of the causes for aseptic necrosis of lunar bone.Treatnent varies according to different classifications,yet without unified or clarified therapeutic regimen.Wrist arthroscopy is a new method for Kienb(o)ck's disease.This article reviews the different stages and treatment methods of traumatic simple Kienb(o)ck's disease,providing reference for clinical treatment.
ABSTRACT
There is a high probability of scaphoid nonunion after scaphoid fracture, which can lead to wrist arthritis and further to progressive aggravation of joint function, seriously affecting daily life and work. Currently, there are a variety of treatment methods for scaphoid bone nonunion at home and abroad, and surgical treatment is the major option, which includes open surgery and arthroscopy assisted minimally invasive surgery. Different operative methods have corresponding indications and contraindications with different therapeutic effects. Arthroscopic assisted technique is novel, minimally invasive, and reliable. This article reviews the treatment methods of scaphoid nonunion, including screw internal fixation, non vascularized bone graft, vascularized bone graft, anastomotic vascularized bone graft, bone block resection, arthrodesis, and arthroscopic minimally invasive surgery, so as to provide references for clinical treatment of scaphoid nonunion.
