![]() ![]() The bone can be fixed in place using either screws or non-absorbable sutures. ![]() The knee is examined for any entrapped meniscus or intermeniscal ligament and any interposing soft tissue is pulled back so that the avulsion fracture can be reduced with an arthroscopic probe applying firm and gentle pressure. The fragments are identified and all soft tissues around them are debrided for proper viewing of the joint. The hematoma (localized bleeding) is removed at first using motorized suction shaver. The arthroscope is inserted through an anterolateral portal (from the side) while the probe and other instruments are passed through an anteromedial portal (from the center). In a minimally invasive arthroscopic procedure, tiny incisions are made on the front of the joint. The injured knee is placed on a leg holder over the radiolucent operating table as postoperative plain X-rays will be taken after the procedure to verify whether reduction and fixation are satisfactory. Extension casting or open reduction and internal fixation (ORIF) if required for type II fractures.The treatment options for tibial spine avulsions include Treatments for Tibial Eminence Spine Avulsions Type III: Completely displaced fracture.Type II: Fracture is rotated but the rear end or posterior part of the avulsion is still in place.Type I: Non-displaced or minimally displaced spine avulsion.Tibial spine avulsions are classified into: This injury may occur because of abnormal outward bending or twisting injuries caused by a sudden halt of moving joints, excessive flexion (bending inwards) and internal rotation, which usually occur during skiing and motor vehicle accidents. Causes for Tibial Eminence Spine Avulsions Tibial eminence spine avulsion fracture is the avulsion (tearing away) of the tibial eminence. What is Tibial Eminence Spine Avulsion Fracture? The medial spine provides attachment for the anterior cruciate ligament (ACL). The tibial eminence consists of the medial and lateral spines. Between these plateaus, the bone is raised to form the tibial eminence. The upper aspect of the shinbone is made up of the medial (towards the inner side of the knee) and lateral (towards the outer side of the knee) plateaus (flat regions). The knee joint is made up of bones, the thighbone, and shinbone (lower leg), which articulate with each other. Tibial Eminence Spine Avulsion Fracture Anatomy of the Tibial Eminence ![]()
