Method for Glenoid Bone Defect Plasty in Recurrent Shoulder Instability

Abstract

Technique for glenoid bone defect plasty in posttraumatic shoulder instability using the porous titanium nickelide (Ti-Ni) graft is presented. This method is an alternative to Latarjet operation and autoplasty with the graft from the iliac crest. The shape and size of the graft was determined by MSCT data and the graft was sawed out from cylindrical billets with diameter of about 2.5 cm and wall thickness - 1 cm. Two screw holes were drilled and the graft was placed into the defect. That technique was applied in 6 patients with long lasting history of recurrent anterior instability and instability relapses after shoulder stabilization using other surgical techniques. Preoperative shoulder functional state by Rowe scale averaged 35.0 points versus 93.3 points after operation. One year follow up showed no cases of instability relapse. The advantages of this technique are the possibility of accurate glenoid anatomic shape reconstruction, absence of graft resorption and reduction of intervention duration.
