A Stener lesion is a complete tear of the ulnar collateral ligament (UCL) from the thumb proximal phalanx at the level of the metacarpophalangeal (MCP) joint that is displaced superficial to the adductor pollicis aponeurosis, leading to interposition of the aponeurosis between the UCL and the MCP joint.
How long does it take to heal from MCL tear?
Recovery time for an MCL injury depends on the severity of the damage. On average, these injuries take six weeks to heal. No matter the grade of the tear, initial treatment focuses on immobilizing the knee and reducing pain and inflammation.
Is a torn MCL a serious injury?
Ligaments consist of strong connective tissue. A sprain stretches the ligament, which can become loose after a severe injury. A tear is a more severe injury that splits the ligament in two. When someone tears the MCL, it may not hold the knee in place as securely.
Is it bad to walk on a torn MCL?
If the MCL or ACL tears, the result is usually pain, swelling, stiffness, and instability. In most cases, the injured person can still walk with the torn knee ligament. But the movement will be severely limited, not to mention painful. Surgery may be the best route to a pain-free life, with amazing success rates.
Do all stener lesions need surgery?
Treatment / Management Type 2: UCL tears that are displaced less than 3 mm can be healed with immobilization alone. Type 3: UCL tears that are displaced more than 3 mm will usually fail immobilization and most patients with require surgery. Type 4: Stener lesion will require surgery in all cases.
Does a Stener lesion hurt?
A Stener lesion is a type of traumatic injury to the thumb. It occurs when the aponeurosis of the adductor pollicis muscle becomes interposed between the ruptured ulnar collateral ligament (UCL) of the thumb and its site of insertion at the base of the proximal phalanx….

Does knee brace help MCL?
Healing often requires the athlete to wear a brace for an MCL injury that prevents valgus stress on the knee and its healing MCL. The brace has hinges that prevent side-to-side motion, but it allows full flexion and extension.
What does an MCL tear feel like?
MCL injuries hurt. Most people feel pain along the inside edge of the knee, and they also have swelling. You might hear a pop when the damage to the knee takes place, and your knee may lurch to the side. You may find it hard to walk, or feel like you can’t put pressure on the leg with the hurt knee.
What is the difference between meniscus and MCL?
MCL stands for medial collateral ligament and is located on the inside of the knee. The MCL originates on the femur (thigh bone) and inserts on the tibia (large bone of the lower leg). The MCL splits slightly at the knee joint and some fibers also insert onto the medial meniscus (cushion inside the knee).
Can MCL heal itself?
If you have a mild MCL strain, it can heal on its own with rest, ice, and other self-care. You’ll need to raise your sore knee when you put ice on it, keep weight off the joint, and protect and compress the injury with a knee brace or elastic bandage.
What is a Stener lesion of the medial collateral ligament?
MRI NEWSLETTER: Stener-like Lesion of the Medial Collateral Ligament of the Knee. An injury of the MCL is one of the most common ligamentous injuries of the knee. MCL injuries are graded 1-3, with grade 1 consisting of edema next to the MCL, Grade 2 with abnormal signal within the tendon, and Grade 3 with disruption of the tendon.
What is a Stener lesion of the MCL?
This type of MCL tear has been called the “MCL Stener lesion.” These are frequently associated with ACL tears and require early surgical intervenon. The “wave” sign has been described in these lesions with a wavy course of the MCL; interestedly, this is not seen in femoral avulsions of the MCL.
What is the pathophysiology of Stener-like lesions on the tibia?
Stener-like lesions represent a high percentage of tibia-sided sMCL avulsions, are found most often with pes anserinus interposition, and are frequently associated with multiligamentous injury, suggesting high-energy trauma.
What is the prevalence of distal tibial Grade 3 sMCL tears?
Review of 65 knee MRI examinations identified 20 cases of distal tibial grade 3 sMCL tear. Of the distal tears, 12 (60%) were Stener-like lesions and six (30%) were borderline lesions.
