About This Presentation

Description : Check out this medical PowerPoint presentation titled "Traumatic Elbow Instability" by David Ring MD PhD.

This medical PowerPoint presentation is about traumatic elbow instability, a condition in which there is excessive movement of the elbow joint, leading to pain, instability, and a decreased range of motion. It usually results from an injury to the ligaments that stabilize the elbow joint.

There are different types of elbow instability based on the direction of the instability, including anterior (forward), posterior (backward), and lateral (sideways). Anterior instability is the most common type and is often caused by a fall on an outstretched hand or a direct blow to the elbow.

Symptoms of traumatic elbow instability include pain, swelling, tenderness, and a feeling of instability or looseness in the elbow joint. Treatment typically involves rest, physical therapy, and sometimes surgery to repair or reconstruct the damaged ligaments.

If left untreated, traumatic elbow instability can lead to chronic pain, reduced function, and the development of arthritis in the elbow joint. Therefore, it is important to seek medical attention promptly if you suspect you have this condition.

Transcript

Slide 1-

Traumatic Elbow Instability David Ring MD PhD Updated April 2016
Slide 2-

Simple Elbow Dislocation No associated fractures Complete or near complete capuloligamentous injury Extensive muscle injury Nearly always stable after reduction No advantage to surgery if stable No more than 2 weeks immobilization
Slide 3-

Elbow Dislocation Usually posterolateral Can dislocate with anterior band of MCL intact Posteromedial pattern Less common Possibly more unstable
Slide 4-

Slight Subluxation “Drop Sign” This is like pseudo-subluxation in the shoulder. The combination of extensive muscle and ligament injury and guarding due to pain create a slight sag. IMPORTANT: distinguish from subluxation that will cause articular damage Drop sign After active flexion exercises
Slide 5-

Slight Subluxation “Drop Sign” Management: Avoid varus stress (shoulder abduction) Active flexion Overhead exercises Drop sign After active flexion exercises
Slide 6-

Unstable Simple Elbow Dislocation Uncommon Older women (simple fall) Young men (high-energy)
Slide 7-

Unstable Simple Elbow Dislocation Ligament / muscle reattachment to epicondyles External fixation Cross pinning
Slide 8-

Cross Pinning Useful bail out Stiff and located is preferred to subluxation Stiffness usually worked out easily 2.0mm pins exit proximally for retrieval in case of breakage Can be placed with local Only needed for 3 weeks. Bury if needed longer
Slide 9-

Chronic Simple Elbow Dislocation Jupiter and Ring JBJS 2002 Treatment: Open reduction and hinged external fixation No ligament reconstruction 5 patients: dislocated for 2 to 9 months Stable elbow, > 100 degrees motion in all patients
Slide 10-

Medial Collateral Ligament Insufficiency Throwing athletes Chronic attenuation Inability to throw 95 mph fastballs
Slide 11-

LCL Insufficiency Recurrent Simple Elbow Dislocation Insufficiency of the lateral collateral ligament Adolescent elbow dislocation Iatrogenic

Posterior Dislocation + Radial Head Fracture
Slide 22-

Posterior Dislocation + Radial Head Fracture 24 patients Ulnohumeral dislocation with radial head fracture Cast 1 month +/- radial head resection “Results better than generally thought” Secondary procedures for radial head No problems with instability
Slide 23-

Posterior Dislocation + Radial Head Fracture 23 patients Excision of radial head and cast INSTABILITY in patients with CORONOID fractures (4 patients)
Slide 24-

Terrible Triad Posterior dislocation Radial head fracture Coronoid fracture
Slide 25-

Terrible Triad Only patients with INSTABILITY had CORONOID fractures (4 patients)
Slide 26-

Terrible Triad Ring, Jupiter, Zilberfarb JBJS 2002 11 patients Regan and Morrey Type 2 coronoid fractures 7 redislocated in splint or cast 5 redislocated after operation Only 4 patients with satisfactory results

Principles of Treatment Restore contour and dimensions of trochlear notch Contoured dorsal plate Fixation of coronoid Bridge fragmentation
Slide 46-

Treatment Tips Pin the olecranon to the trochlea Consider a temporary external fixator for a complex fracture
Slide 47-

Coronoid Exposure Through an olecranon fracture Lateral Kaplan interval with elevation of ECRL origin Removal of radial head fragments Medial Over the top (tip) Split in FCU by ulnar nerve (medial facet) Elevate entire flexor-pronator mass from dorsal (base fracture)
Slide 48-

Coronoid Provisional Fixation Coronoid fixation with plate then reduce and fix olecranon Pin fragments to trochlea Need to immobilize the elbow

Exercises During Recovery If the LCL is injured, avoid varus stress (shoulder abduction) for 3-4 weeks. Overhead exercises can be helpful. If fixation is tenuous a 3-4 week period of immobilization is acceptable Active, self-assisted elbow flexion and extension and forearm rotation are the key Encourage patients to get into a “healthy stretch” mindset. It hurts, but it helps.
Slide 61-

Summary The LCL is more important than the MCL The ligaments will heal if you keep the elbow concentric, even when treated late Active motion adds to stability (avoid varus stress) Even small coronoid fractures can be a problem
