One prior study by Kocher et al.8 identified an entrapment of the anterior horn of the medial meniscus, intermeniscal ligament, or anterior horn of the lateral meniscus in 26% of type II fractures and 65% of type III fractures. There is a linear bone fragment adjacent to the lateral margin of the lateral tibial plateau, consistent with a segond fracture. These injuries occur at an estimated frequency of approximately 3 per 100,000 and are mainly found in children aged 8 to 14 years.

Tibial spine fracture management is typically based on the type of underlying fracture. 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. 36, No. . A Tibial Eminence Fracture, also known as a tibial spine fracture, is an intra-articular fracture of the bony attachment of the ACL on the tibia that is most commonly seen in children from age 8 to 14 years during athletic activity. 13, No. 2, Topics in Magnetic Resonance Imaging, Vol. Finally, the knee is extended to look for any impingement in the intercondylar notch. Postoperatively, the knee is immobilized in an extension knee immobilizer for 2 weeks. It also avoids the complications and morbidity of arthrotomy.

The presence of the tibial spine fracture and large hemarthrosis also indicates a likely ACL injury. The joint and fracture bed is cleared of hematoma and debris using continuous irrigation. Both the suture and screw fixation are technically challenging.22 Suture fixation will be further discussed in Chapter 33. Associations patella tendon or quadriceps tendon rupture The ACL insertion on the tibia can be used as an anatomic guide for reduction, and reduction should be confirmed by direct visualization under arthroscopy.

Tibial Eminence (Spine) Avulsion Fracture ORIF. 54, No. The typical patient is an adolescent male approaching skeletal maturity with well-developed quadriceps. 32, No. 4. Diagnostic arthroscopy is performed under tourniquet from the standard anterolateral portal. The anterior cruciate ligament fibers were intact and attached to the avulsed tibial spine fragment. Segond fracture Avulsion fracture of knee . Log-in above or renew your membership today. 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. 4, Seminars in Roentgenology, Vol. 93, No. C, Dual Polydioxanone (PDS) bite through the anterior and posterior part of ACL base (inset) with external picture of knee showing the PDS coming out through the 5.5 mm cannula in the anteromedial portal.

The patients are allowed nonweight-bearing walking with axillary crutches from first postoperative day. Type I fractures are usually treated with immobilization whereas type II fractures typically undergo an initial attempt at closed reduction followed by arthroscopic or open reduction and fixation if needed. 110, No. During terminal knee extension the tibia and femur move in opposite directions, Avulsion fractures of the ACL attachment to the tibial spine are most prevalent in children 8-14 yrs of age but are seen in adults >35 yrs of age who have low bone density. Knee XRay. Recognition of characteristic imaging features and familiarity with musculotendinous anatomy will aid in accurate diagnosis of avulsion injuries. Mean postoperative Lysholm score at final follow-up was 98.12. 5A). modify the keyword list to augment your search. Type I fractures are characteristically nondisplaced fractures of the tibial spine. to maintaining your privacy and will not share your personal information without It is also easy to take the bite from medial side to lateral side of ACL base in a straight line, and it does not entail the use of any complex maneuver inside the knee joint. 24, No. This typically involves separation of the tibial attachment of the ACL to variable degrees. External picture of the knee (inset). No patient showed extension deficit. We use a suture fixation approach for fractures consisting of a small bone fragment or with significant comminution. 5, Journal de Traumatologie du Sport, Vol. 4, Clinical Medicine Insights: Arthritis and Musculoskeletal Disorders, Vol. Type I fractures failing nonoperative management typically have late displacement, which can occur despite adequate immobilization. MRI injury patterns in surgically confirmed and reconstructed posterolateral corner knee injuries. 77, No. 32, No. This information is informative regarding potential obstacles to fracture reduction.

It is typically caused by forceful hyperextension or a direct blow upon the distal femur with the knee in flexion. After that, the fracture is reduced and held using the ACL jig. Figure 1a shows a gadolinium-enhanced transverse MRI scan at the level of the coracoid. Geiger D, Chang EY, Pathria MN et-al.

Data is temporarily unavailable. 3, Journal of Surgical Case Reports, Vol. Monto RR, Cameron-Donaldson ML, Close MA et-al. Now, the needle is withdrawn out of the tibial tunnel and then the PDS loop in 2 tibial tunnels is pulled out of the joint. Pediatric patients are most commonly affected due to the weakness of the subchondral bone, which causes the bone to fail before the ACL. 6, Journal of the Korean Society of Radiology, Vol. B, Lateral view of postoperative radiograph shows completely reduced tibial spine avulsion fracture (black arrow). 40, No. . Tibial spine or anterior cruciate ligament (ACL) bony avulsion is not an uncommon injury. J Bone Joint Surg [Am] 1977; 59:1111-1114. Arthroscopy now provides the benefit of decreased morbidity, and as such, the trend is to offer arthroscopic fixation even for type II fractures. 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. 198, No. 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. Tibial tuberosity avulsion fractures are uncommon. Segond fractures are frequently (~75%) associated with anterior cruciate ligament injury. 1, Clinical Journal of Sport Medicine, Vol. 1): group A (20 patients underwent low-dose CT scan and 3D-printed fracture models before surgeries performed by inexperienced surgeons, simulating the operations in low- and middle-income countries), group B (20 patients underwent standard-dose CT, and 3D models were printed before surgeries performed by experienced . 32.3). 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. 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. Based on the findings of the clinical and radiographic examination, the diagnosis of an avulsion fracture of the AcL, posterior medial, and posterior lateral meniscus root was made and surgery was recommended to the patient. Meniscal entrapment, although suspected on MRI, is definitively diagnosed during the diagnostic arthroscopy. 209, No. 4A). Please try after some time.
