Emergency physicians will usually opt for radiography as their initial imaging modality, which has several disadvantages in evaluating tibial avulsion fractures. Pediatric patients are most commonly affected due to the weakness of the subchondral bone, which causes the bone to fail before the ACL. 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. Further when the UB suture is pulled, the fracture tends to reduce in its crater with tension in the ACL returning to the normal (Fig. We usually use an ACL tibial guide to manipulate the fracture fragment (an angled microfracture pick or K-wire can also be used). Adequate immobilization can be obtained with either a brace or a cast.

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. Diagrammatic representation of the bite through the base of ACL from the IV cannula needle. 3, Journal of Surgical Case Reports, Vol. 34, No. 32.4) and the structural continuity of the ACL is determined. Currently, arthroscopic suture fixation of fragment has become a popular method as it is a rigid method of fixation, MRI compatible, and most importantly it obviates the need for implant removal later.2 Suture fixation technique is of 2 types: one is based upon ligament itself and the other depends upon the bone fragment.3,4 Techniques based upon bone fragment using suture fixation through 2 drilled holes through the reduced fragment may not be always possible due to technical difficulties or comminution of the fragment. Probing is done to check the reduction and adequate tension in ACL. Classification; Imaging; Stress-Related Apophyseal Avulsion Fractures 4, 9 January 2020 | RadioGraphics, Vol. At the time of the initial physical therapy visit, the patient was ambulating with axillary crutches, bearing weight as tolerated on his left lower extremity. Pandey, Vivek MS (Ortho); Acharya, Kiran MS (Ortho); Rao, Sharath MS (Ortho); Rao, Sripathi MS (Ortho), Department of Orthopaedic Surgery, Kasturba Medical College, Manipal, Karnataka, India. 25, No. 15, The American Journal of Sports Medicine, Vol. 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. We describe a simple and very effective arthroscopic technique suitable for types II to IV tibial eminence avulsion fractures, using high-strength sutures through the ACL utilizing simple intravenous cannula needle. 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. Fracture of the lateral tibial plateau and proximal fibula fracture with avulsed ACL tibial insertion and posterolateral corner injury, Schatzker classification of tibial plateau fractures. 5, British Medical Bulletin, Vol. tibial spine; avulsion; arthroscopy; rigid fixation. 23, No. Inset shows tied Ultrabraid over suture button. A diagnostic knee arthroscopy is initially performed including the patellofemoral joint and both the medial and the lateral compartments. 4, Seminars in Roentgenology, Vol. Tibial spine fractures occur through the subchondral bone at the base of the medial tibial spine and are ACL equivalent injuries. N.B. He subsequently presented to the emergency department for evaluation. Case study, Radiopaedia.org (Accessed on 12 Dec 2022) https://doi.org/10.53347/rID-38580. 5A). Figure 1a shows a gadolinium-enhanced transverse MRI scan at the level of the coracoid. Tibial avulsion fractures and partial tears are more common in younger, less rigid skeletons that may absorb the forces of trauma. Anterior cruciate ligament (ACL) avulsion fracture or tibial eminence avulsion fracture is a type of avulsion fracture of the knee. 6, MUSCULOSKELETAL SURGERY, Vol. Arthroscopy now provides the benefit of decreased morbidity, and as such, the trend is to offer arthroscopic fixation even for type II fractures. Tibial Tubercle Avulsion Pathology Avulsion fracture of the tibial tubercle, usually by sudden violent muscle contraction Can often also take off the whole anterior part of the tibia (not just the tubercle) Symptoms Pain and swelling around the tibial tubercle With a displaced fracture, it is unlikely that the patient is able to straight leg raise B, Lateral view of postoperative radiograph shows completely reduced tibial spine avulsion fracture (black arrow).

It can be caused by traumatic traction (repetitive long-term or a single high impact traumatic traction) of the ligament or tendon. The failure of bone most commonly results from an acute event with the application of usually sudden, tensile force to the bone through the soft tissue, or when chronic .

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. Further, the needle is pierced into the ACL substance posteriorly at the junction of avulsed bone and ligament and advanced laterally out of the ACL substance. Spine bones. IV. The patient was a 32-year-old male who sustained a noncontact left knee injury during a quick pivot on a planted left foot, while playing flag football. Furthermore, arthroscopy allows the surgeon to rule in/out injury to the intra-articular structures under direct visualization. Arthroscopic Repair in Tibial Spine Avulsion Fractures Using Polyethylene Terephthalate Suture: Good to Excellent Results in Pediatric Patients Arthroscopic Repair in Tibial Spine Avulsion Fractures Using Polyethylene Terephthalate Suture: Good to Excellent Results in Pediatric Patients Authors 2006;19 (3): 187-90. 1, Veterinary and Comparative Orthopaedics and Traumatology, Vol. 4, Radiologic Clinics of North America, Vol. Case-control study on MDCT and MRI for the diagnosis of complex fractures of tibial plateau. 38, No. The cartilaginous avulsion fracture of the tibial spine was not revealed by radiographs because it was limited to the cartilaginous portion of the proximal tibia. modify the keyword list to augment your search. 32, No. This carries the Ultrabraid sutures out of the joint as they were into the loop (Fig. 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.
