~About Shoulder Dislocation and Shoulder Instability
Have you ever experienced shoulder dislocation or have "an uneasy feeling that your shoulder might be dislocated on a daily basis"?
Shoulder joint dislocation is one of the most common dislocations of all joints in the bodyandFailure to perform proper repair, immobilization, and rehabilitation leads to recurrence and chronic instability.Possibility.
In this issue, we will discuss shoulder dislocation and shoulder instability, including symptoms, examination, treatment, and what we do.
What is shoulder dislocation?
The shoulder joint (glenohumeral joint) is,Joint consisting of the humeral head and scapular articular fossaand while it has a very wide range of motion, it has limited structural stability.
Therefore,Shoulder joints are prone to dislocation due to falls or sports traumaCharacteristics,Approximately 45% of all dislocations occur in the shoulder jointIt is also said that
There are different types of dislocation directions, but 90% and above are "anterior dislocations".
[Main symptoms
- Shoulder.Severe pain and difficulty moving
- Due to dislocationSense of deformity or discomfort in the shoulder
- Due to compression of the axillary nerveNumbness and paresthesia in the lateral shoulder(Many recover spontaneously.)
Injuries prone to complications
Shoulder joint dislocation can result inComplicated bone and soft tissue injuriesThe following is a list of the most important factors that can be considered when selecting a new product:
- Bankart InjuryArticular lip injury of the anterior margin of the glenoid fossa
- Hill-Sachs Damage: Posterior lateral humeral head depression injury
- Proximal humerus fracture(especially in the elderly at the time of injury)
These damages are,Causes re-dislocation and joint instabilityTherefore, accurate assessment and response are important.
[Inspection
The clinic performs the following testsDiagnose direction of dislocation and complicationsI will do so:
- X-ray examination (front, Y view)Check for: dislocation direction and fracture
- CT and MRI(When necessary): Detailed evaluation of injuries to the glenoid fossa and head (Bankart injury, Hill-Sachs injury, etc.)
Treatment: Repositioning and fixation of dislocation
Treatment of shoulder joint dislocation begins withRepositioning a dislocated joint back to its original positionIt starts with
An example of a restoration method
- Stimson ActThe method: lying face down with arms hanging down, weights attached, and waiting for spontaneous recovery.
- Traction and abduction method: How to reposition the shoulder while abducting it on your back.
In the case of restorations,Combined with pain relief and local anesthesiaIt is also possible to do so.
Fixation and subsequent actions
After the restoration, to stabilize the joints.Fixed for 3-4 weeksThe following is a list of the most common types of products that can be used.
The two types of fixation are internal rotation fixation and external rotation fixation, and the choice depends on the site of injury and the risk of recurrence.
What is repetitive shoulder dislocation?
After initial dislocation,A condition in which minor external forces or daily activities cause repeated dislocation again.refers to
This is,Injury to the joint lip and ligaments from the initial dislocation, which remains with inadequate healing, resulting in decreased joint stabilityThe reason for this is to
- The initial dislocation wasVery high rate of re-dislocation if it occurs at a young age (teens and 20s)
- To prevent recurrence of fundamentalRequires surgical therapy (e.g., joint lip repair)may be
What is shoulder instability?
Shoulder instability is,A condition in which subluxation or instability of the shoulder occurs due to innate looseness of the joint, not necessarily due to traumaIt is.
- Likely to dislocate in certain directions or postures
- Shoulder.Pain, weakness, numbness, instabilityVarious symptoms such as
Treatment
The basic approach is conservative therapy (rehabilitation):
- Avoidance of movements prone to dislocation and instability
- Exercise therapy to strengthen periarticular muscles and improve stability
*In many cases, the disease heals spontaneously in middle and high school students,More than 30% improve with conservative therapyIt is considered to be a
Examinations and treatments available at Ikejiri-Ohashi Sera Clinic
The clinic has the following medical systems in place
Inspection
- Medical interview and physical examination (shoulder deformity, neurological symptoms, etc.)
- X-ray examination (frontal, Y view, axial)
- as necessaryReferrals to higher medical institutions for CT, MRI, and other detailed examinations
Treatment
- Dislocation repair (analgesia as needed)
- Appropriate immobilization (3-4 weeks) and recurrence prevention instruction after repair
- Rehabilitation and surgical referral for repetitive dislocation and instability
- Step-by-step support for return to sports
Summary
Shoulder joint dislocation is not "OK if it goes back to normal",Subsequent fixation, management, and rehabilitation are very important.It is.
We need to take appropriate action,They may suffer from re-dislocation and chronic shoulder instability.
At Ikejiri-Ohashi Sera Clinic,Consistent support for diagnosis, repair, fixation, and rehabilitation to prevent recurrence of dislocationThe company is doing so.
