What Have We Learned in the Wrist Joint of Distal Radius Fracture through Wrist Arthroscopy?

Abstract

Abstract Background Wrist arthroscopy is an efficient tool for the surgical treatment of distal radius fracture (DRF). It could show us the various conditions of the radiocarpal joint, its effectiveness seems to overwhelm that of fluoroscopy. Methods Since July 2005, we have performed wrist arthroscopy and plate presetting arthroscopic reduction technique (PART) for 141 extra-articular and 559 intra-articular DRFs and investigated various kinds of intra-articular conditions and advantages of wrist arthroscopy. Results The pathological conditions clarified and the advantages of PART in the surgical treatment of DRF are: (1) accurate reduction of intra-articular fragments is possible compared with fluoroscopic reduction, (2) intra-articular fragments (free body) undetected with radiograph and CT can be recognized, (3) screw protrusion into joint surface can be monitored, (4) intra-articular soft tissue injury associated with fracture can be evaluated and treated, and (5) debridement of joint hematoma can be performed. Severe complications such as tendon rupture, major neurovascular injury or compartment syndrome from arthroscopy were never encountered. Conclusions The volar locking plate fixation and simultaneous arthroscopic intervention is problematic because vertical traction must be applied and released during surgery. PART can overcome these difficulties and achieved good clinical results.
