What is an ACL avulsion fracture?
Anterior cruciate ligament (ACL) avulsion fracture or tibial eminence avulsion fracture is a type of avulsion fracture of the knee. This typically involves separation of the tibial attachment of the ACL to variable degrees. Separation at the femoral attachment is rare 5.
Does ACL avulsion require surgery?
Repair surgery typically is used only in the case of an avulsion fracture (a separation of the ligament and a piece of the bone from the rest of the bone). In this case, the bone fragment connected to the ACL is reattached to the bone.
What attaches to tibial eminence?
The tibial attachment sites of the anterior cruciate ligament(arrowhead), the posterior cruciate ligament (asterisk), the posterior roots of both menisci (not shown), and the anterior root of the lateral meniscus (not shown) are involved.
How do you fix a Segond fracture?
Patients underwent direct Segond fracture repair by either suture alone, suture anchor, or cannulated screw fixation based on the size of the lesion, followed by a 2-incision hamstring autograft intra-articular reconstruction.
How long does a Segond fracture take to heal?
In a mean 59.1 months (range, 24-180 months) of follow-up, the Segond group had the same results regarding anteroposterior and rotational stability as the control group. The authors also mentioned that time to fracture healing was 4 months (range, 3-30 months) after injury.
What is a tibial avulsion fracture?
A tibial tubercle avulsion fracture is usually an injury to the knee occurring in adolescence, during the transitional phase of physeal closure just prior to completion of growth.
What is tibial eminence fracture?
Tibial eminence fracture, a bony avulsion of the anterior cruciate ligament (ACL) from its insertion on the intercondylar eminence,1 was first described by Poncet in 1875. 2 Also known as tibial spine fractures, these injuries occur most commonly in skeletally immature patients between the ages of 8 and 14 years.
What is tibial eminence?
The tibial eminence, also known as the tibial spine, is the tibial attachment of the anterior cruciate ligament (ACL). Fractures occur when a child falls off a bicycle or is injured while playing sports.
What is a thoracolumbar burst fracture?
Thoracolumbar Burst Fractures are a common high-energy traumatic vertebral fractures caused by flexion of the spine that leads to a compression force through the anterior and middle column of the vertebrae leading to retropulsion of bone into the spinal canal and compression of the neural elements.
What happened to 32 year old male with L4 burst fracture?
(OBQ06.93) A 32-year-old male sustained an L4 burst fracture in a car accident five days ago. On initial presentation he was neurologically intact and treated in a thoracolumbar orthosis. In the last two days he has noticed increasing difficulty voiding, decreased perianal sensation, and weakness to ankle plantar flexion.
What is an ACL tear?
ACL tears are common athletic injuries leading to anterior and lateral rotatory instability of the knee. Diagnosis can be suspected clinically with presence of a traumatic knee effusion with increased laxity on Lachman’s test but requires MRI studies to confirm diagnosis.
What is the status of a 25-year-old post anterior cruciate ligament (ACL) reconstruction?
(OBQ11.215) A 25-year-old male is one year status post anterior cruciate ligament (ACL) reconstruction using patellar bone-tendon-bone (BTB) autograft. He complains of persistent instability with certain activities.
