Main
- Only a trauma and orthopaedic surgeon performs joint reduction: attempts to do it yourself risk damaging the vessels and nerves of the limb.
- Signs of a dislocation: severe pain, deformity of the joint, inability to move, swelling and redness around the affected area.
- Numbness or blueness of the limb is a reason to call an ambulance immediately, as the nerves or vessels are compressed.
- X-ray confirms the displacement of the bones and rules out a fracture, while tomography shows the condition of the ligaments and soft tissues.
- Immobilisation of the limb with a fixing bandage or plaster cast is needed so that the ligaments have time to recover after reduction.
What is a dislocation
A dislocation is the displacement of bones in a joint, in which their normal contact is disrupted. Most often the shoulder, elbow, knee and ankle joints are affected, as well as the fingers.
What happens in the body
The joint is structured so that the head of one bone fits precisely into the socket of another, while the ligaments and capsule hold them together. In a dislocation this pair of bones loses its usual position, and the joint surfaces no longer contact as before. The ligaments around the joint are stretched and sometimes torn, because they are the first to take on the force of the impact. The joint capsule, which usually tightly encloses the articulation, is also damaged and lets the head of the bone slip out. Because of this, the shape of the joint itself changes: it looks unusual, and the limb loses its usual support. The person notices that movements in this area have become impossible or sharply limited, and any attempt to move the limb causes pain. If the bones are not put back in place in time, the surrounding tissues swell and are injured further, so the joint needs a doctor's help in the first hours.
What causes it to develop
- A fall onto an outstretched limb: the body weight falls on the arm or leg, and the joint goes beyond its usual range of motion.
- A sudden movement with hyperextension of the joint: the limb deviates further than its structure allows, and the ligaments cannot hold the bones.
- A blow or collision during sport: contact types of exertion produce a sharp jolt that displaces the head of the bone from the joint socket.
- Lifting a heavy weight with a jerk: a sudden effort without warming up the muscles creates a load that the ligamentous apparatus cannot cope with.
- Congenital weakness of the ligamentous apparatus: with this feature the joints are less stable, so displacement occurs even with a minor impact.
Who encounters this more often
Most often, dislocation is encountered by people whose lives involve falls, sudden movements and physical overload. These include athletes in contact and team sports, as well as those who work at height or on slippery surfaces. In children, the joints and ligaments are still forming, so even ordinary play with jumping can end in displacement of the bones. In older people, the ligaments lose elasticity, and the muscles support the joint less well, which increases the risk during a domestic fall. Congenital weakness of the ligamentous apparatus makes a person vulnerable regardless of age and lifestyle. Repeated episodes in the same joint indicate that it has become less stable and requires attention. Therefore, at the first signs of displacement it is important not to postpone a visit to the doctor and not to try to reduce the joint yourself.
What symptoms can there be?
Symptoms of a dislocation usually appear immediately after an injury or a sudden movement. It is important to recognise the signs in time so as not to harm the joint and to get help.
How it is noticed at the very beginning
The main signs of a dislocation appear immediately after an injury or a sudden movement; sometimes in the first minutes a person feels sharp pain in the area of the joint. Movement in the damaged joint becomes impossible or sharply limited, and an attempt to move the limb intensifies the unpleasant sensations. Many attribute this condition to fatigue or a sprain if the pain is tolerable and the swelling is not yet pronounced. Gradually, a sensation of displacement or noticeable deformity in the area of the joint is added to the pain, which can be seen when comparing with the healthy side. Swelling and redness around the joint increase, the skin becomes hot, and the limb may appear changed in shape. If numbness or tingling appears in the limb, this indicates that nerves or vessels are affected. At the first suspicions of a dislocation, do not try to reduce the joint yourself and seek medical help as soon as possible.
Signs that occur most often
- Sharp pain in the joint: occurs immediately after an injury or a sudden movement and intensifies with any attempt to move the limb.
- Sensation of displacement or deformity: the joint looks changed in shape, and when compared with the healthy side the difference is noticeable.
- Inability to move the limb: movement becomes sharply limited or completely impossible, which prevents leaning on an arm or a leg.
- Swelling and redness around the joint: the skin over the damaged area swells, reddens and becomes hot to the touch.
- Numbness or tingling in the limb: such a sign indicates possible compression of nerves or vessels and requires urgent help.
When to seek help urgently
Examinations and tests
Examination for a dislocation is needed to confirm the displacement of the bones and to assess whether nearby structures have been affected. Below is what exactly the doctor does at the appointment and which investigations he may order.
How the examination begins
The examination begins with inspection and palpation of the injured joint, because these actions give the doctor the first information about the condition of the limb. The doctor assesses the shape of the joint, its mobility and the condition of the skin over it, comparing with the healthy side. On palpation he identifies painful areas and feels displaced bony prominences that should not normally be present. The altered shape of the joint and the forced position of the limb are noticeable already on external inspection and immediately indicate displacement. If the person tries to move the limb himself, the pain sharply intensifies, and the movements remain limited. To confirm the diagnosis and rule out a fracture, radiography is ordered, which shows the position of the bones. Therefore it is worth coming to the appointment with X-rays already taken, if they are available, so that the doctor does not waste time on a repeat referral.
What is ordered and what it shows
What is worth preparing for the appointment
- Images and reports: take all previously taken X-rays and their descriptions, so that the doctor can see the dynamics and does not order a repeat investigation unnecessarily.
- History of the injury: recall and write down exactly how the injury occurred and how much time has passed since that moment, because the choice of examination depends on this.
- Complaints: describe in your own words what troubles you most — pain, swelling or inability to move, so that the doctor sets the right priorities during the examination.
- Previous injuries: list past injuries of the same joint, if there were any, since repeated dislocations require a more careful examination.
- List of questions: formulate in advance what you want to clarify with the doctor, so as not to forget anything important during a short appointment.
Which doctor should I see?
This section explains which doctor to consult for a dislocation, what happens at the first appointment and what areas of care the treatment consists of. Below are guidelines for choosing a specialist and understanding how treatment is organised.
Which specialist manages this condition
A dislocation is managed by an orthopaedic trauma surgeon, and it is to them that patients are referred when a joint displacement is suspected. The doctor examines the injured area, assesses the position of the limb and checks whether movement below the site of injury is preserved. A habitual dislocation, that is, a recurring displacement in the same joint, also remains within their remit. If a specialist of this profile is not available nearby, initial care is provided by the on-call trauma surgeon in the hospital's emergency department. They confirm that it is indeed a dislocation and not a fracture, and decide where to refer the person next. If a large joint is damaged or a ligament tear is suspected, the involvement of a surgeon may be required. Delaying seeking help is dangerous because the joint remains displaced while the surrounding tissues gradually swell. The sooner the person is examined by an orthopaedic trauma surgeon, the easier it is to return the joint to its correct position.
What the treatment consists of
- Reduction of the joint: the specialist returns the head of the bone to its physiological position, and without this step the remaining measures lose their meaning.
- Pain relief before the procedure: the doctor relieves the pain so that the muscles relax and the reduction is performed carefully, without unnecessary trauma.
- Immobilisation of the limb: a fixing bandage or plaster cast is applied for several days or weeks so that the ligaments have time to recover.
- Physiotherapy and therapeutic exercise: gradual work on mobility restores the joint's range of motion and strengthens the muscles around it.
- Surgery: intervention is discussed for habitual dislocations or ligament damage, when conservative measures do not give the required result.
What depends on the patient themselves
The outcome of recovery largely depends on how regularly the person is followed up by the orthopaedic trauma surgeon after reduction. If the scheduled examinations are missed, the doctor will not see how the ligaments are healing and will not adjust the fixation in time. Wearing the bandage or plaster cast for the agreed period directly affects how firmly the joint will hold its position. Removing the fixation on one's own ahead of time increases the risk of repeated displacement and the development of a habitual dislocation. Therapeutic exercise sessions have an effect only when performed systematically, and not from time to time. An abrupt return to previous loads, when the joint has not yet grown strong, often leads to a new visit for help. The patient should clarify with the doctor in advance which movements are permissible at each stage and when they can return to their usual routine.
What helps prevent an exacerbation?
Preventing a repeated dislocation is helped not by a one-off effort, but by a person's own everyday decisions. Below are the habits, observations and regular visits to the doctor that reduce the risk of an exacerbation.
What is changed in habits
Strengthening muscles and ligaments with regular exercise is the foundation of what a person can do themselves. Weak muscles hold the joint in its usual position less well, so even ordinary everyday strain becomes risky. When playing sports, protective devices should be used: braces and supports take on part of the load in the vulnerable area. Safety technique during training is more important than the result: sudden movements and falls are most often what lead to injury. It is useful to avoid sudden movements in everyday life too — when lifting heavy objects, on a slippery road, on the stairs. Previous joint injuries must not be left unattended: an incompletely treated injury makes the ligaments weaker and increases the risk of a repeat one. If swelling or discomfort appears after exertion, this is a reason to reconsider the intensity of exercise, not to endure it. It is more sensible to exercise more often and more moderately than rarely and at the limit of one's capabilities.
What should be kept under control
- Regularity of exercise: exercises to strengthen muscles and ligaments should be systematic, not occasional, otherwise the joint loses support.
- Protective devices: braces and supports for sports loads are selected for a specific joint, and they need to be worn during the activity, not after.
- Technique of performing movements: following safety technique reduces the risk of sudden movements and falls, which most often lead to injury.
- Condition after injuries: timely treatment of joint injuries is important to complete, since an incompletely treated injury weakens the ligaments for a long time.
- The joint's reaction to load: swelling, discomfort or instability after an activity is a signal to reduce the intensity and discuss it with a doctor.
How often to see a doctor
A regular examination by a doctor is needed even when the joint does not bother you and your wellbeing seems good. Ligaments and muscles change gradually, and an unnoticed weakening of support manifests itself after the next load. At the appointment, the doctor assesses the stability of the joint, the range of movement and how the person tolerates their usual physical load. Previous injuries require special attention: if the injury was treated long ago, it is worth clarifying whether any consequences remain that increase the risk. Swelling, pain after an activity or a feeling of instability when walking become reasons to come earlier than a planned visit. The frequency of visits depends on the type of activity and the condition of the joint, so it is better to agree on it with a doctor rather than determine it yourself. Such monitoring allows the load and habits to be adjusted in time, while the changes are still reversible.
What is worth remembering
A dislocation is a condition in which the joint surfaces shift and stop touching in the usual way, while the ligaments and capsule around them are damaged. The discussion of dislocation should be concluded with a few points that help make the right decision in the first hours.
Main conclusions
A dislocation is not a bruise or a sprain, but a displacement of the joint surfaces, in which the joint loses its usual support and stops working as a single whole. Only a doctor can reduce a dislocation, because an unskilful movement can damage blood vessels, nerves and surrounding tissues. Before examination, it is important to immobilise the damaged area and not try to put the joint back in place yourself. Attempts to "yank" an arm or a leg at home often turn a simple injury into a severe one and lengthen recovery. If a limb is affected, it should not be leaned on or loaded even if the pain is tolerable. A repeated dislocation in the same joint occurs more often if the ligaments have not had time to strengthen after the first episode. Therefore, it is sensible not to postpone a visit to the doctor and later to do what he recommends for strengthening the joint.
