ADVERTISEMENT: Supporters see fewer/no ads. This technique can also be used in young patients with open physis as the diameter of the 2 tibial tunnels is only 1.5 mm each, which will not damage the growth plate. In cases where there is interdigitation of the meniscus between the plateau and the fracture fragment, a probe can be used to carefully elevate the meniscus from below the tibial spine fragment. .

TECHNIQUE STEPS Preoperative Patient Care . Tibial spine fractures occur through the subchondral bone at the base of the medial tibial spine and are ACL equivalent injuries. 2A). Tibial spine avulsion fractures are most commonly classified based on an algorithm devised by Meyers and McKeevers.18 The classification scheme relies on the degree of displacement of the avulsed fragment from the fracture base. Segond fracture Avulsion fracture of knee . 24, No. With the knee flexed, the tibial spine avulsion fragment is anatomically reduced back into its bed on the tibia. Tibial spine fractures typically occur at the bony insertion of the anterior cruciate ligament (ACL) on the tibia. Furthermore, fixation using a dual high-strength suture material ensures rigid fixation and early mobilization, which is imperative to avoid knee stiffness.

After that, the fracture is reduced and held using the ACL jig. This end of the PDS is grabbed using the arthroscopic grasper through the lateral loop of PDS and pulled out through the AM portal (Fig. tibial spine; avulsion; arthroscopy; rigid fixation. From the case: Tibial spine fracture with anterior cruciate ligament avulsion - type 4 ct Axial bone window Sagittal bone window CT Axial bone window The large tibial spine avulsion is clearly demonstrated on the CT. Tests Imaging Plain radiographs: AP and lateral views of the knee usually are adequate. Ligament suture methods require special instruments such as penetrator or suture passers for taking a bite through the substance of ACL.3 They are expensive and in addition, these wide bore instruments can damage the ACL substance if the bite has to be repeated. For this reason, patients with type I fractures being managed nonoperatively should be closely monitored for this complication during the first 6 weeks after injury.20 Early motion after evidence of fracture union is important to prevent knee stiffness. suppl_1, 2022 Radiological Society of North America, SCIENTIFIC EXHIBIT - Continuing Medical Education, To read the full-text, please use one of the options below to sign in or purchase access, Purchase this article as pay-per-view (unlimited access for 24 hours), https://doi.org/10.1148/radiographics.19.3.g99ma05655, US and MRI of Pelvic Tendon Anatomy and Pathologic Conditions, Pearls and Pitfalls for Soft-Tissue and Bone Biopsies: A Cross-Institutional Review, Radiographic Review of Avulsion Fractures RadioGraphics Fundamentals | Online Presentation, Sports and the Growing Musculoskeletal System: Sports Imaging Series, Imaging of Sports-related Injuries of the Lower Extremity in Pediatric Patients, Taking the Stress out of Evaluating Stress Injuries in Children, Avulsion Fractures of the Knee: Imaging Findings and Clinical Significance1, Pitfalls in MR Image Interpretation Prompting Referrals to an Orthopedic Oncology Clinic1, Traumatic Musculotendinous Injuries of the Knee: Diagnosis with MR Imaging1. 1, Arthroscopy: The Journal of Arthroscopic & Related Surgery, Vol. 3. 4, American Journal of Physical Medicine & Rehabilitation, Vol. The jig is then placed in the lateral-most edge of crater, and another tunnel is drilled with 1.5 mm K-wire. 1, Clinical Journal of Sport Medicine, Vol. 1C). Tibial spine avulsion fracture is not an uncommon injury and a displaced fracture can lead to malunion or nonunion resulting in pain, flexion deformity, and instability. 5, Clinics in Sports Medicine, Vol. 0. We usually use an ACL tibial guide to manipulate the fracture fragment (an angled microfracture pick or K-wire can also be used). 2, Clinics in Sports Medicine, Vol. 15, The American Journal of Sports Medicine, Vol. A patient has right shoulder pain. This information is informative regarding potential obstacles to fracture reduction. Once the base is identified, trail reduction of the avulsed fragment is attempted using ACL jig (Conmed, Largo, FL) by pressing upon the fragment through AM portal. 32, No. A high rate of concomitant injury with tibial spine fractures has been reported in the literature.16,17 As such, magnetic resonance imaging (MRI) for further radiographic assessment of tibial spine injuries is recommended.

Figure 1 Treatment of type II fractures is more controversial, and historically good results have been reported from both the operative and nonoperative management of type II fractures.21 Similar to type I fractures, mild forms of type II fractures can be managed nonoperatively with cast or knee immobilization if there is near-anatomic reduction. Fracture of the tibial spine in adults and children: a review of 31 cases.

Bone marrow edema was noted in a pivot shift injury pattern1 involving the lateral femoral condyle and the lateral tibial plateau (FIGURE 2, FIGURE 3); there was also a fracture of the posterior lateral tibial cortex at the site of the bone marrow edema. The Ultrabraid suture is tied one by one over the bone bridge between the 2 tibial tunnels or a suture button (Smith & Nephew) if the bone bridge is narrow keeping the knee in 30-degree flexion and tibia pushed posteriorly. The intercondylar tibial eminence fracture is one of the most common knee fractures in children 1 and is usually seen between the ages of 8 and 14 years 2. 40, No. Next, the menisci are inspected for involvement of the anterior meniscus in the fracture fragment (Fig. Mechanism. J Bone Joint Surg [Am] 1977; 59:1111-1114. The joint and fracture bed is cleared of hematoma and debris using continuous irrigation. Early detection and appropriate treatment of these fractures are essential in minimizing patient's disability in range of movement, stability and reducing the risk of documented complications. Tibial spine fracture management is typically based on the type of underlying fracture. Background]. 23, No. [1] This fracture pattern is considered an anterior cruciate ligament (ACL) equivalent injury in children. Unable to process the form.

The lateral radiograph clearly demonstrates a fracture of the tibial spine with the fracture fragment in the joint space. All patients resumed to their previous activity levels. The term tibial eminence refers to the area between the medial and lateral tibia plateaus on the proximal tibia, and consists of the medial and lateral tibial spines. Radiographs of the left knee revealed findings consistent with a tibial spine avulsion fracture, while magnetic resonance imaging confirmed a medial tibial spine avulsion fracture. 2.3.1 Fractures of the Pelvic Ring. 32, No. The topic of his research was: The evaluation of the results of surgical Treatment of distal tibial fractures by fibula-pro tibia fixation.
