A Modified Surgical Technique for Minimally Invasive Arthroscopic Total Wrist Fusion.

Arthroscopic total wrist arthrodesis is a procedure with minimal violation of extensor compartments and less scar formation, compared with open wrist arthrodesis. In this paper, we would like to present our experience with a modified surgical technique for arthroscopic total wrist arthrodesis.  After an arthroscopic cartilage removal through radiocarpal and midcarpal portals, the operation is continued under fluoroscopic control. In this technique, four wires are inserted separately in four various directions (as described in the paper), followed by insertion of self-tapping cannulated screw, under fluoroscopic control.  In this prospective study, a total of four patients underwent arthroscopic total wrist arthrodesis using our surgical technique within a period of 2 years. All four patients were followed for a minimum of 3 months for possible complications and functional outcome.  The results were satisfactory, and no complication was observed. All the patients had complete union after 12 weeks, and the fusion was radiographically complete in all cases by 12 weeks. All patients were happy with their functional outcomes.  Using the described modified arthroscopic technique, we did four total wrist arthrodeses with minimal scar, no complication and acceptable functional results.
