Lacunar ligament sprain is an uncommon injury that affects a small, crescent-shaped ligament in the groin region. A lacunar ligament sprain is an injury in which the lacunar ligament—a structure that helps support the groin area—is overstretched or torn. Like other sprains, the injury may occur due to excessive force or a sudden twist. Although this ligament is less well-known than major knee or ankle ligaments, injury to it can lead to groin pain and mobility issues.
Key points:
- It is often associated with groin pain.
- It may be confused with other groin injuries.
- Early diagnosis and treatment can prevent long-term problems.
Anatomy and Pathophysiology
Understanding the structure and function of the lacunar ligament is essential when discussing its sprain.
Structure
- Location: The lacunar ligament (sometimes called Gimbernat’s ligament) is located in the groin area. It forms a crescent shape at the medial (inner) aspect of the inguinal region.
- Composition: Like other ligaments, it is made up of dense connective tissue that provides support and stability.
- Relationship to Surrounding Structures: It works closely with muscles and other ligaments in the groin, contributing to the overall integrity of the inguinal canal.
Blood Supply
- Main Vessels: The lacunar ligament receives a small blood supply from nearby branches of arteries such as the obturator and inferior epigastric arteries.
- Importance: Adequate blood flow is crucial for the healing process when the ligament is sprained or injured.
Nerve Supply
- Innervation: Sensory nerve fibers, including those from the ilioinguinal nerve and sometimes branches of the genitofemoral nerve, supply the area.
- Pain Signal: These nerves transmit pain signals when the ligament is overstretched or torn.
Functions
- Support: Provides structural support to the groin region.
- Stability: Helps maintain the position of the inguinal canal, reducing the risk of herniation.
- Movement: Works in tandem with nearby muscles to allow smooth movement during activities like walking or running.
Types of Lacunar Ligament Sprain
Sprains are generally classified by their severity:
Grade I (Mild):
- Minimal tearing of ligament fibers.
- Slight pain and swelling.
- Normal joint function is usually maintained.
Grade II (Moderate):
- Partial tear of the ligament.
- Noticeable pain, swelling, and some loss of function.
- May require a longer recovery period.
Grade III (Severe):
- Complete tear of the ligament.
- Severe pain, instability, and significant impairment.
- Often requires surgical intervention.
Common Causes
The following are potential causes or risk factors that can lead to a lacunar ligament sprain:
- Sudden twisting motion during sports or exercise.
- Direct trauma to the groin area.
- Overstretching during high-intensity activity.
- Muscle imbalance causing uneven stress on the ligament.
- Weak core muscles that fail to support the groin.
- Improper warm-up before physical activity.
- Overuse injuries from repetitive motions.
- Accidents such as falls or collisions.
- Heavy lifting with poor form.
- Running on uneven surfaces.
- Sudden changes in direction while playing sports.
- Lack of flexibility in the hip and groin muscles.
- Previous groin injuries that weaken the area.
- Aging, which can reduce tissue elasticity.
- Genetic predisposition to connective tissue weaknesses.
- Inadequate rest between intense workouts.
- High-impact sports like soccer or hockey.
- Improper technique during exercise.
- Trauma from motor vehicle accidents.
- Stress on the body from overall physical fatigue.
Symptoms to Watch For
The following symptoms might indicate a lacunar ligament sprain:

Diagnostic Tests and Assessments
A thorough diagnosis involves several clinical tests and imaging studies:
- Physical examination by a healthcare professional.
- Medical history review to understand prior injuries.
- Pain assessment scales to gauge intensity.
- Range of motion tests.
