How to Fix a Subluxation: Treatment and Safety

Treating a subluxation depends entirely on which joint is affected, how it happened, and whether the partial displacement resolves on its own or needs hands-on intervention. A subluxation, where a joint’s surfaces partially separate without fully dislocating, can range from a momentary slip that self-corrects to a persistent misalignment requiring emergency care. The treatment spectrum runs from simple rest and bracing through guided rehabilitation to surgical stabilization, and the safety profile varies dramatically depending on the approach chosen and the body part involved.

What Makes a Subluxation Different from a Dislocation

In a full dislocation, the joint surfaces lose all contact and typically cannot return to their normal position without intervention. In a subluxation, the bones partially shift out of alignment but retain some contact. This distinction matters for treatment because many subluxations reduce spontaneously, meaning the joint slips back into place on its own within seconds or minutes. Others stay partially displaced and require a clinician to guide the bones back. The line between subluxation and dislocation is not always crisp in practice, and imaging often plays a role in clarifying which category an injury falls into.

The joints most prone to subluxation include the shoulder, kneecap, fingers, jaw, and various segments of the spine. Each has its own anatomy, risk factors, and treatment pathway, so a one-size-fits-all approach does not exist. A subluxating kneecap in a teenager after a sports collision calls for a very different plan than a recurring shoulder subluxation in someone with a connective tissue disorder.

When to Treat It as an Emergency

Most subluxations are not life-threatening, but certain warning signs demand immediate medical attention. If the area around the joint turns pale, feels cold, or loses sensation, there may be damage to the blood vessels or nerves that run near the joint. Clinicians maintain a high index of suspicion for arterial injury whenever there is gross deformity, significant soft tissue damage, or signs of reduced blood flow such as pallor, coolness, tingling, or muscle weakness.¹ These situations are surgical emergencies, not something to manage at home.

Even without vascular compromise, a joint that remains visibly deformed, is locked in an abnormal position, or causes escalating pain after the initial injury should be evaluated promptly. Attempting to force a joint back into place without proper training risks fracturing bone, tearing ligaments, or trapping nerves. The safest first-aid step for a suspected subluxation that has not self-reduced is to immobilize the joint in whatever position it is in, apply ice to limit swelling, and get to a clinician who can assess and treat it properly.

How Clinicians Diagnose and Assess Subluxation

Diagnosis usually begins with a physical examination tailored to the specific joint. For the shoulder, which is one of the most commonly subluxating joints, a combination of provocation tests provides high diagnostic accuracy. The apprehension, relocation, and release tests together offer strong specificity for anterior instability, and additional hyperlaxity tests help paint a full picture of how loose the joint actually is.²

Imaging fills in what hands-on examination cannot. Plain X-rays can reveal bony abnormalities and gross displacement. For more subtle cases, especially in the cervical spine, newer radiographic methods using ratios to estimate the distance between vertebrae have shown excellent reliability, with sensitivity above 90% and specificity reaching 100% for detecting anterior atlanto-axial subluxation.³ CT scans and MRI are used when the clinician suspects ligament tears, cartilage damage, or other soft-tissue injuries that X-rays miss.

Closed Reduction in a Clinical Setting

When a subluxation or dislocation does not self-correct, a trained clinician performs what is called a closed reduction: guiding the joint back into its normal alignment without surgery. Athletic trainers, emergency physicians, and orthopedic specialists all perform these procedures, and the specific technique varies by joint.⁴

For the shoulder, two common approaches are the modified Milch technique and the traction-countertraction method. In a comparison of the two, the modified Milch technique succeeded in about 84% of cases overall and in 96% of cases when patients with associated fractures were excluded. Patients treated with this gentler approach reported meaningful pain reduction during the procedure and spent an average of only 35 minutes in the hospital, compared with roughly four hours for the traction-countertraction group. Neither group experienced nerve damage or fracture complications after reduction.⁵ The takeaway for patients is that gentler techniques exist and often work well, so a reduction does not have to be a brutal, white-knuckle experience.

What Sedation Looks Like During Reduction

For more complex reductions, especially involving large joints like the hip, procedural sedation helps the muscles relax and keeps the patient comfortable. The choice of sedation agent affects both success and safety. In a study comparing three common approaches for reducing dislocated hip replacements, propofol was associated with the lowest rate of reduction complications at about 9%, compared with roughly 25% for etomidate and 29% for an opioid-plus-benzodiazepine combination. Recovery times were also shorter with propofol, averaging about 25 minutes versus 45 minutes for the opioid combination.⁶ If you are told you need sedation for a reduction procedure, the specific agent matters and is worth discussing with your care team.

Bracing, Taping, and Immobilization

After a subluxation is reduced or self-corrects, the joint usually needs a period of protection. The approach varies by joint. For a first-time patellar (kneecap) dislocation, conservative management typically involves either immobilization with a cylinder cast or removable splint, or functional mobilization with a brace or patellar tape.⁷ The trend in recent years has been toward earlier movement with external support rather than prolonged rigid immobilization, since keeping a joint completely still for weeks can lead to stiffness and muscle wasting that make recurrence more likely.

Taping can play a surprisingly active role in rehabilitation, not just as passive support. In a case involving a young karate athlete with multidirectional shoulder instability, figure-of-eight taping immediately improved active shoulder flexion from 95 degrees to 140 degrees and reduced the sensation of the joint slipping. Over five months of rehabilitation with taping support, active flexion improved from 85 degrees to a full 180 degrees, and the athlete returned to both daily life and competition without difficulty.⁸ Taping gave the joint enough stability for the patient to actually do the strengthening exercises that ultimately fixed the problem.

Rehabilitation and Strengthening

The core of subluxation treatment, regardless of the joint, is rehabilitation. Muscles act as dynamic stabilizers, and strengthening them compensates for whatever ligament laxity or structural damage allowed the subluxation to happen. For the shoulder, that means targeting the rotator cuff and the muscles that control the shoulder blade. For the knee, it means building up the quadriceps and hip stabilizers. For the ankle, it means strengthening the muscles around the lower leg and foot.

In stroke survivors, shoulder subluxation is a common complication because the muscles supporting the joint become weak or paralyzed. A structured rehabilitation program using sling suspension-based active exercises showed measurable improvement: the gap between the shoulder blade and the upper arm bone decreased from 18 mm to 11 mm over four weeks, with corresponding improvements in pain, muscle tone, and functional use of the arm.⁹ A controlled trial of the same approach found that patients doing sling suspension exercises achieved an average reduction in subluxation of about 6 mm, compared with only about 2 mm in a control group doing conventional therapy, a statistically significant difference.¹⁰

For finger subluxations that follow fracture, rehabilitation takes a phased approach: early controlled movement, soft tissue work, progressive strengthening, and finally functional task training. The key principle across joints is that controlled early movement tends to produce better outcomes than prolonged rest.

Preventing Recurrence with Proprioceptive Training

Once a joint has subluxated, it is more likely to do so again. The ligaments may have stretched, the joint capsule may be looser, and the body’s awareness of the joint’s position in space, called proprioception, is often impaired. Training to restore that awareness is one of the most evidence-supported strategies for preventing repeat injuries. An evidence review of proprioceptive training for ankles found that people with a history of sprains who completed balance and coordination programs had about a 36% lower rate of repeat sprains compared with those who did not train.¹¹

A six-week proprioceptive exercise program improved both balance and joint position sense in athletes with chronic ankle instability.¹² Interestingly, adding kinesiology tape to the program did not provide extra benefit beyond the exercises alone. A separate randomized trial found that both balance training and traditional strength training improved dynamic balance in people with chronic ankle instability, though strength exercises were more effective at restoring the ability to sense joint position and vibration.¹³ The practical implication is that a prevention program works best when it includes both balance challenges and raw muscle strengthening.

The Safety Question Around Spinal Manipulation

The term “subluxation” carries an entirely different meaning in chiropractic practice than it does in orthopedic medicine. In chiropractic theory, a vertebral subluxation refers to a misalignment of spinal segments that is said to interfere with nerve function, and spinal manipulation is offered as the primary treatment. This is the context in which many people encounter the word, so the safety of spinal manipulation deserves a frank discussion.

A large systematic review covering 47 randomized trials and over 9,000 participants found that spinal manipulative therapy for chronic low back pain had effects similar to other recommended treatments for short-term pain relief, with a small improvement in physical function. Most observed adverse events were musculoskeletal, temporary, and mild to moderate in severity.¹⁴ So for low back pain, spinal manipulation is roughly as helpful as other mainstream therapies and not dramatically more dangerous. The concern sharpens when the manipulation involves the neck.

A systematic review of adverse effects found that over 200 patients were suspected to have been seriously harmed by spinal manipulation, with the most common serious injuries being vertebral artery dissections, which can lead to stroke. Milder side effects such as soreness, headache, and stiffness occurred in 30% to 61% of all patients receiving manipulation.¹⁵ A prospective national survey put the risk of a serious adverse event at roughly 1 in 10,000 treatment sessions immediately after cervical spine manipulation, rising to about 2 in 10,000 when measured over the following week.¹⁶

Those numbers are small in absolute terms but not trivial, especially because vertebral artery dissection can be catastrophic. If you are considering neck manipulation for what you believe is a subluxation, it is worth discussing with your physician first. The evidence suggests that for spinal pain, manipulation offers modest benefits that are comparable to other therapies, so you have alternatives that avoid the small but real vascular risk to the neck.

Subluxation in Connective Tissue Disorders

For people with hypermobile Ehlers-Danlos syndrome (hEDS), subluxations are not one-time injuries but a recurring fact of life. The underlying collagen abnormalities make joint connective tissue fundamentally looser and more fragile, so standard stabilization strategies face an uphill battle. Shoulder instability in this population can cause lifelong pain and functional disability, and treatment is complicated by the severity of the instability as well as the abnormal connective tissue itself.¹⁷

People with hEDS frequently deal with chronic widespread muscle pain, autonomic dysfunction, and recurrent subluxations across multiple joints.¹⁸ Rehabilitation in this group has to be more cautious, typically starting with low-resistance exercises in supported positions and progressing very slowly. Overly aggressive strengthening can itself trigger subluxation episodes. The goal shifts from curing instability to managing it well enough to maintain function and quality of life.

A psychological dimension complicates recovery for many people with joint hypermobility. Kinesiophobia, the fear of movement triggered by pain, is common in this population and correlates strongly with overall fatigue severity.¹⁹ When someone’s joints have repeatedly slipped out of place, it is entirely rational to become wary of movement, but that wariness leads to deconditioning that worsens the instability. Breaking that cycle often requires a therapist who understands hypermobility and can build confidence gradually.

When Surgery Becomes the Answer

Surgery is generally reserved for subluxations that keep happening despite adequate rehabilitation, or for cases where structural damage (torn ligaments, fractured bone, loose bodies inside the joint) prevents the joint from stabilizing on its own. The specific procedure depends on the joint and the nature of the damage. Shoulder stabilization may involve reattaching a torn labrum, tightening the joint capsule, or transferring a bone graft to deepen the socket. Knee procedures may realign the groove that the kneecap tracks in or reconstruct the ligament that holds it in place.

For the jaw, chronic recurrent temporomandibular joint dislocation can be addressed with the Dautrey procedure, which surgically repositions the bony eminence that the jaw slides over. In a comparative study, this procedure produced stable, lasting correction of chronic jaw dislocation with minimal complications. The surgery increased the height of the bony barrier by an average of about 3.7 mm and shifted its lowest point forward by about 4.5 mm, physically preventing the jaw from slipping out of the socket while preserving normal mouth opening.²⁰

The Role of Trauma in Creating Chronic Instability

A single traumatic event can set the stage for ongoing subluxation by permanently stretching the ligaments that hold a joint together. This has been studied in the cervical spine, where whiplash injuries cause measurable changes. Research on cervical capsular ligaments showed that whiplash-exposed ligaments had significantly greater elongation than uninjured controls, even at very low forces. This increased laxity may be one mechanism behind the chronic pain and clinical instability that persists in some whiplash patients long after the initial injury.²¹ Understanding this helps explain why some people develop recurrent subluxations after an accident that seemed relatively minor at the time. The ligament stretching may not show up on standard imaging, yet it changes the mechanical behavior of the joint permanently.

Subluxations in Children

Children present unique challenges. Their bones are still growing, and the cartilaginous growth plates that have not yet hardened can make imaging harder to interpret. Certain subluxations are more easily missed in children because the clinical and radiological signs are less obvious than in adults. Radial head dislocations (where the top of the forearm bone slips out of position at the elbow) are a classic example: they are far more common in adults, so when they occur in children, the diagnosis is sometimes delayed.²²

The most familiar pediatric subluxation is “nursemaid’s elbow,” where a sudden pull on a toddler’s hand causes the radial head to partially slip out of the annular ligament. This is typically reduced quickly and painlessly by a trained clinician with a simple forearm rotation, and it rarely requires imaging or follow-up. However, children who experience subluxations of other joints, particularly the shoulder or kneecap, deserve the same structured rehabilitation as adults to prevent recurrence. The temptation to assume a child will “grow out of it” can lead to chronic instability that follows them into adulthood.
