Dislocations and blockages at the elbow

What are elbow dislocations and blockages?

A dislocation occurs when the joint partners of the elbow (humerus, ulna, radius) completely lose their normal contact. In the case of a subluxation, the contact is only partially disturbed. A blockage describes a sudden, painful restriction of movement, often due to pinching or loose joint bodies. Both situations can occur acutely after an event or occur repeatedly (recurrently).

• Dislocation: complete dislocation, often after a fall or twisting
• Subluxation: partial dislocation, e.g. B. in children (“Chassaignac”) or ligament laxity
• Mechanical blockage: Movement stops abruptly, often with snapping or binding, e.g. B. through free joint bodies

Important: Dislocations are potentially time-critical as accompanying injuries to ligaments, cartilage, capsule and nerves are possible. Blockages are usually less urgent, but should be investigated if they recur or cause pain.

Anatomy and function of the elbow

The elbow connects the upper arm bone (humerus) with the ulna and radius. It enables bending/stretching as well as rotational movement of the forearm (pronation and supination). Stability comes from the exact shape of the joint surfaces, the joint capsule, the collateral ligaments (ulnar and radial), as well as the muscles and tendons.

• Joints: humeroulnar joint, humeroradial joint, proximal radioulnar joint
• Stabilizers: medial and lateral collateral ligament, capsule, muscles/tendons
• Nerves running through: etc. Ulnar nerve, median nerve, radial nerve (important in dislocations)

Even small deviations, for example due to ligament injuries or loose joint bodies, can disrupt fine control and lead to instability, blockages or pain.

Typical symptoms

• Acute, stabbing pain in the elbow
• Visible misalignment, swelling, hematoma (common with dislocation)
• Sudden stop of movement with snapping/clamping (in case of blockage)
• Sensory disturbances, tingling, weakness in the hand/fingers (indication of nerve involvement)
• Limited flexion, extension and/or rotation mobility
• Feeling of insecurity or “folding away” (instability), especially after a previous dislocation

Warning signs that require rapid medical attention include persistent misalignment, numbness, cold hand, severe pain at rest or loss of arm function.

Common causes and risk factors

• Falling onto the hand or outstretched arm
• Sports injuries (contact, throwing and falling sports)
• Sudden pulling on the forearm in children (subluxation of the radial head)
• Ligament laxity, previous dislocation with incomplete healing of the ligaments
• Joint wear or cartilage damage with loose joint bodies
• Occupational stress with high repetition frequency and vibration

Inadequate torso and shoulder blade stability, unhealed previous injuries and inadequate technique during stress are risk-promoting factors.

Diagnosis in practice

The diagnosis is based on a structured history and a careful clinical examination including neurovascular control. Imaging is used to confirm the diagnosis, assess accompanying injuries and plan therapy.

The aim is to enable safe, conservative treatment planning and to identify risks such as unstable injury patterns or nerve involvement early.

Conservative therapy: first stabilize safely

Many dislocations and blockages can be treated conservatively provided there are no relevant associated injuries or persistent instability. The prerequisite is professional reduction (adjustment) and an assessment of stability.

• Reduction of the dislocation: promptly, gently, in a suitable environment; Depending on the situation, in an emergency or in the practice/outpatient setting
• Short-term immobilization: splint/orthosis, usually a few days to a few weeks - as short as possible, as long as necessary
• Early functional mobilization: guided movements to avoid stiffness
• Physiotherapy: Stabilization of the surrounding muscles, coordination, economy of movement
• Pain and inflammation management: cooling, medication tailored to your needs; Infiltrations only as indicated
• Everyday life and sports advice: step-by-step plan with load increase and technical training

In the case of mechanical blockages without a structural danger (e.g. small free joint bodies without entrapment), manual therapeutic mobilization, targeted exercises and anti-inflammatory measures can help. In cases of repeated entrapment or persistent mechanical obstruction, surgical removal should be considered.

When do interventions make sense?

Surgical measures are considered if conservative options are not sufficient or there is a risk of permanent damage. The decision is made after weighing findings, complaints, functional goals and individual factors.

• Unstable dislocation with accompanying ligament or bony injuries
• Recurrent instability despite therapy
• Trapping free joint bodies with mechanical blockage
• Injuries with nerve involvement or relevant misalignment
• Complex fracture dislocations

Possible procedures include ligament suturing or reconstruction, bony stabilization, arthroscopic removal of free joint bodies or open reduction in complex situations. The aim is to reduce pain and improve function; there can be no guarantee.

Acute help: What to do if a dislocation or blockage is suspected?

• Immobilize: Fix your arm close to your body, no forced movement
• Cool: 10-15 minutes with a cloth, taking breaks
• Elevate slightly if possible
• No attempts of adjustment of your own
• If you have a misalignment, severe pain, numbness, pale or cold hand: go to the emergency room

For short-term blockages without persistent symptoms, gentle care and cooling are often sufficient. Recurring blockages should be clarified orthopedically.

Course, prognosis and possible complications

Many affected people achieve good function with consistent conservative therapy. The course depends on the injury pattern, stability, accompanying findings and quality of rehabilitation.

• Possible complications: Stiffness, persistent instability, cartilage damage, loose joint bodies, development of osteoarthritis
• Rehabilitation: slow increase in load, regular exercises, technique training
• Return to sport/work: individually based on stability, strength and mobility

Close monitoring of progress helps to avoid overload and to adapt the therapy path if necessary.

Prevention and self-exercises

• Building shoulder blade and trunk stability as a basis for the elbow
• Technique training in throwing, climbing and contact sports
• Progressive increase in load instead of jumping to high intensities
• Regular mobility and strength exercises for the forearm and upper arm muscles
• Protective measures depending on the sport: taping/orthosis after consultation
• Consistent rehabilitation after previous injuries

Exercises should be pain-adapted and carried out in a controlled manner. If you are unsure, physiotherapy will show you suitable exercises and progressions.

Special situations: children, sports, work

In children, subluxation of the radial head (“Chassaignac”) typically occurs, often after pulling on the arm. This can usually be reduced in a way that is gentle on the joints. What is crucial is rapid detection and education to avoid recurrences.

• Children: Handle gently, no strain on the hand, quick clarification
• Sport: Prioritize technique and core stability, adequate regeneration
• Work: Ergonomics, breaks, if necessary temporary adjustment of loads and aids

Individual stress profiles require tailor-made rehabilitation plans. We coordinate this with you and, if appropriate, with the trainer or company medicine.

Subtopics and further information

For targeted in-depth information, you will find detailed profiles on specific clinical pictures and mechanisms:

• Elbow dislocation: causes, diagnosis, treatment options
• Subluxation of the elbow: forms of instability in children and adults
• Blockage caused by free joint bodies: symptoms, imaging, treatment
• Blocked radio head: special features in children and in sports

In addition, subject areas on joint structures, ligaments, tendons and nerves help you classify your symptoms.

Differential diagnoses at the elbow

Not every immobility or pain is a dislocation or mechanical blockage. The following areas should be considered:

• Intra-articular joint disease, inflammation or osteoarthritis
• Tendon and muscle problems such as tennis or golfer's elbow
• Ligament and capsule injuries without complete dislocation
• Bone injuries such as radial head or coronoid fractures
• Nerve constriction syndromes or functional disorders

A structured orthopedic examination helps to accurately narrow down the cause and avoid overtreatment.
