Impingement syndrome
(bottleneck syndrome)

 Article Download

What is special about our treatment?

In conservative therapy, we treat with injections, medication and special physiotherapy exercises. With surgical therapy, the arm can be moved normally again on the first postoperative day. Depending on the pain, driving is possible again 2-3 days after the operation, working after approx. 1-2 weeks.

What is impingement syndrome?

Impingement syndrome under the acromion often causes discomfort during certain movements. This diagnosis must be very carefully differentiated from other complaints in the shoulder area.

Pain occurs mainly at night and during movements in internal rotation (e.g. when putting on a jacket), which then lead to stabbing pain in the shoulder area. This is caused by a mechanical constriction of the muscles under the acromion. The pain does not normally radiate into the arm or the cervical spine, but is mainly felt directly in the shoulder area. There is often no pain at rest, but only during movement or when sleeping on the shoulder at night.

1 | How do your problems manifest themselves?

Symptoms

The problems are often caused by a constriction under the acromion, either bony due to the bursa or due to a thickened tendon.
The pain is located directly in the shoulder area and becomes noticeable with certain movements. It does not normally radiate into the arm or the cervical spine.
Stitch-like pain without radiation, always with certain rotational movements, also night pain
When the arm is rotated internally, e.g. when fastening a seatbelt in a car or putting on a jacket
Stage 1: There is slight discomfort during rotational movements in the shoulder joint.
Stage 2: Increasing symptoms, occasionally also at night with the onset of limited mobility.
Stage 3: Increasing restriction of mobility with stab-like discomfort with small movements.
Stage 4: Almost all movements in the shoulder area are painful (especially at night) and mobility decreases significantly due to pain.

2 | How do we tackle the problem?

Examination & diagnosis

  • Detailed medical history & precise shoulder-specific examination
  • Ultrasound examination with corresponding diagnostics
  • Special X-ray examination to determine the angle of the acromion, the AC joint and any bony spurs present
  • A targeted injection can usually directly eliminate the pain for hours to a few days, which supports the diagnosis.
  • An additional magnetic resonance imaging examination is often carried out to rule out an injury to the muscles or tendon.

4 | How exactly does your treatment proceed?

Treatment

In the case of impingement syndrome, the first step is always several weeks of conservative treatment in the form of physiotherapy, medication and local infiltration if necessary. X-ray and sonographic examinations are also carried out to determine whether there is a bony constriction or whether there are changes in the tendon area. In rare cases, arthroscopic (minimally invasive) surgery by widening the space below the acromion is performed at the very end of an unsuccessful conservative treatment.

5 | What methods are there?

Details on conservative treatment

Physiotherapie

Special physiotherapy is used to promote the mobility of the shoulder. The shrunken capsule is stretched and the muscles are retrained.

In this way, the humeral head is re-centered in the shoulder area and the impingement is reduced or even eliminated.

We usually recommend physiotherapy twice a week for 6 weeks.

ACP syringe

Especially in the case of tendon injuries or irritations, such as those caused by impingement syndrome, we have observed very good treatment successes with ACP therapy in our practice in Freiburg.

Patients report a significant reduction in pain and an improvement in mobility.

For degenerative changes in the tendon, we recommend 3-6 ACP injections, one week apart.


‍Themode of action of ACP

Many injuries to the human body heal themselves. Behind these complex healing processes are growth factors from the blood.

During treatment with ACP, blood is taken from the patient with a small special syringe, similar to the way you would have a small blood count at your GP.

This blood is then specially processed so that only the growth factors responsible for healing remain in a highly concentrated form.

The body's own active ingredient obtained in this way is then injected into the affected tendon. At the site of the injection, the body's healing mechanisms kick in and the inflammation and associated swelling recede. This creates more space under the acromion.

The muscles can then glide better again, the joint runs more smoothly and the tendon can recover. In professional sport in particular, the treatment of irritated tendons with ACP has now become standard practice - ACP can often even replace harmful cortisone treatments in the long term.

Kortison

Medication is used to combat inflammatory changes in the bursa. If the inflamed bursa swells again in this way, more space is created under the acromion. The muscles can then glide better again, the joint runs more smoothly and the tendon can recover.

This can also be supported by a one-off cortisone infiltration directly into the bursa.

Cortisone infiltration is covered by all health insurance companies.

Acupuncture

Acupuncture can be used very well as supportive pain therapy and to reduce the tendency to swell in osteoarthritis.

1x - 2x per week for 10 weeks

6 | How does the operation proceed?

Operation details

During the operation, the constriction in the shoulder and thus the pinching of the tendon is removed in a minimally invasive keyhole procedure. A small burr is inserted to correct any bony changes under the acromion.

The inflamed bursa in this area is also removed during the operation, but in most cases it re-grows after a short time without becoming inflamed again.

The space between the humeral head, muscles and acromion is widened so that the muscles can glide normally again.

Wieis the difference in our process?

We perform this operation exclusively arthroscopically (using the keyhole principle). Thanks to particularly gentle techniques, there is usually no major bleeding. The muscles are not injured, so there is very little swelling.

‍Nodrainage:
We can almost always dispense with the insertion and subsequent removal of a drain.

No long immobilization of the arm
:
The patient can move their arm again on the first postoperative day.

‍Specialpain blockade:
Intraoperatively, patients receive an injection into the nerves of the arm to block pain, so that patients feel no pain for up to 24 hours immediately after the operation.

‍Nostitches necessary:
‍The
use of self-dissolving cosmetic sutures means that our patients no longer need to remove stitches.    

How long does the operation take? Outpatient or inpatient?

The operation usually takes 30 minutes and is performed under general anesthesia.

In most cases, we recommend that impingement syndrome surgery is performed on an inpatient basis, as a pain block (anesthesia of the nerves by injection) is used specifically in our procedure. As a result, the patient usually has no discomfort on the first postoperative day.

WieHow quickly can I move my arm again after the operation?

You will be able to move your arm again on the first postoperative day. A drain is not inserted and no bandage is required.

WannCan I go back to work after the operation?

Depending on the work activity 1-3 weeks after the operation.

WannCan I do my sport again?

Sports that do not put a lot of strain on the shoulder, such as jogging, can be performed from the 3rd week onwards.

For sports that put strain on the shoulder, breaks of up to 6 to 12 weeks may be necessary. We will be happy to advise you on this and create an individual plan for you to build up the load.

Wascan happen if I need the operation but do not have it?

In the long term, a bony constriction can lead to damage to the tendon. This can result in a complete rupture of the muscles and partial loss of arm function.

WelcheAre there any risks associated with the operation?

With today's special minimally invasive techniques, complications are extremely rare. The worst and extremely rare complication would be a joint infection.

As our arthroscopic surgery involves a great deal of fluid irrigation, infection practically never occurs. However, should this occur, an antibiotic would have to be administered. It may be necessary to irrigate the joint again.

There is normally no risk of major injury to the tendon, bone or nerves.
