Elbow Instability & Ligament Injuries
Elbow Instability & Ligament Injuries: Causes, Symptoms, and Treatment Options
Elbow instability and ligament injuries occur when the stabilising structures of the elbow joint are damaged, leading to looseness, pain, and potential joint dislocation. These conditions are often seen in athletes engaged in throwing sports or activities that place repetitive stress on the elbow. Dr Ben McGrath, an orthopaedic specialist, provides accurate diagnosis and targeted treatments to help patients recover from elbow instability and ligament injuries and regain stable, functional movement.

What is Elbow Instability & Ligament Injury?
Elbow instability and ligament injuries involve damage to the ligaments responsible for holding the elbow joint in place. The elbow relies on several ligaments, including the ulnar collateral ligament (UCL) and lateral collateral ligament (LCL), to maintain stability during movement. When these ligaments are stretched or torn, the elbow may become unstable, leading to pain, limited motion, and, in severe cases, joint dislocation.
Common Symptoms of Elbow Instability & Ligament Injuries
Patients with elbow instability and ligament injuries may experience:
- Elbow Pain: Pain during movement, especially when performing activities that place stress on the elbow, like throwing.
- Looseness or Instability: A sensation of the joint “giving way” or feeling loose, particularly with specific motions.
- Reduced Range of Motion: Difficulty fully extending or flexing the elbow due to pain or instability.
- Swelling and Bruising: Localised swelling or bruising, particularly following an injury.
- Clicking or Locking Sensations: Audible sounds or sensations of the joint catching, often due to ligament damage or joint misalignment.
These symptoms may vary depending on the type and severity of the ligament injury.
Causes and Risk Factors for Elbow Instability
Elbow instability can result from:
- Trauma: Falls, direct impacts, or dislocations can stretch or tear the ligaments supporting the elbow.
- Repetitive Stress: Frequent high-stress activities, such as throwing or lifting, can gradually weaken ligaments and cause microtears.
- Overuse in Sports: Sports like baseball, tennis, and javelin that involve repetitive throwing motions put significant stress on elbow ligaments.
- Previous Injury: A history of elbow injury, particularly dislocations, increases the risk of recurrent instability.
- Poor Technique or Weak Muscles: Incorrect techniques or weak shoulder and arm muscles can increase stress on the elbow ligaments.
Recognising these factors can help in preventing ligament injuries and managing instability effectively.
Types of Ligament Injuries in the Elbow
There are several types of ligament injuries associated with elbow instability:
- Ulnar Collateral Ligament (UCL) Injury: Common among throwing athletes, particularly in the dominant arm. UCL injuries can cause pain on the inner side of the elbow and lead to instability.
- Lateral Collateral Ligament (LCL) Injury: Injury to the LCL can cause instability on the outer side of the elbow, often resulting from trauma or dislocations.
- Posterolateral Rotatory Instability (PLRI): A specific type of instability caused by damage to the lateral ligament complex, leading to the elbow “giving way” during rotational movements.
- Medial Collateral Ligament (MCL) Injury: Though less common, MCL injuries can occur with valgus stress on the elbow, often due to overuse.
Each type of injury affects the elbow differently and requires a tailored approach to treatment.
Diagnosis of Elbow Instability & Ligament Injuries
Dr Ben McGrath uses a detailed diagnostic process to assess elbow instability and ligament injuries:
- Medical History and Physical Examination: Assessment of symptoms, pain location, and instability through specific tests, such as valgus and varus stress tests.
- Imaging Tests:
- X-rays: To rule out fractures, dislocations, or bony abnormalities.
- MRI or Ultrasound: Provides a detailed view of ligament damage, tears, and surrounding soft tissue.
- CT Scans: May be used in complex cases to assess joint alignment and potential loose bodies.
Accurate diagnosis is essential to develop a personalised treatment plan for effective recovery.
Non-Surgical Treatments for Elbow Instability
Non-surgical management is often effective in the early stages or for minor ligament injuries:
- Physiotherapy: Strengthening exercises for the muscles surrounding the elbow, shoulder, and forearm to improve stability.
- Activity Modification: Avoiding activities that place excessive strain on the elbow, such as throwing or heavy lifting.
- Bracing or Taping: Wearing a brace or supportive tape can help stabilise the elbow and prevent excessive movement.
- Medications: NSAIDs may be used to manage pain and inflammation. Always consult a healthcare provider before starting any medication.
- Corticosteroid Injections: In some cases, injections may provide temporary pain relief and reduce inflammation.
These treatments aim to alleviate symptoms, support healing, and strengthen the joint to prevent further injury.
Surgical Treatments for Elbow Instability & Ligament Injuries
Surgery may be required for severe ligament injuries or cases where non-surgical treatments are ineffective:
- Ligament Reconstruction (Tommy John Surgery): A common procedure for UCL injuries in athletes, involving tendon grafting to reconstruct the damaged ligament.
- Lateral Collateral Ligament Repair: Reattaching or reconstructing the LCL to restore stability, especially for posterolateral rotatory instability.
- Arthroscopic Debridement: Removal of damaged tissue or loose bodies that may be causing pain and affecting joint function.
- Internal Bracing: Reinforcement of the ligament with a supportive internal brace to enhance stability while healing.
Dr McGrath discusses surgical options based on the specific ligament injury, activity level, and goals. Post-operative rehabilitation is essential for a successful recovery.

FAQs About Elbow Instability & Ligament Injuries
Many cases, especially minor injuries, improve with physiotherapy, bracing, and activity modification. Surgery is generally reserved for severe or persistent instability.
Recovery times vary but typically range from 6 months to a year, particularly for athletes. Rehabilitation exercises are critical to restoring strength and stability.
Proper technique, strength training, and avoiding repetitive strain on the elbow can help reduce the risk of ligament injuries.
