Pronator Teres Syndrome - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the condition of Pronator Teres Syndrome.
Which nerve is involved with the pronator teres syndrome?
Median nerve.
Pronator teres syndrome is compression of the median nerve at the level of the elbow which occurs more in women.
In the forearm, the median nerve runs between the two heads of the pronatoer teres muscle and then lies between the flexor digitorum superficialis and flexor digitoum profundus muscles.
Pronator teres syndrome could be associated with medial epicondylitis.
The principle symptoms of numbness in the radial 3 1/5 fingers as well as thenar weakness may be mistakenly attributed to carpal tunnel syndrome.
Potential sites for intrapment of the nerve includes:
. Most common cause is due to compression of the median nerve between the two heads of the pronator teres muscle.
. It occurs in people who preform repetitive forceful pronation of the forearm.
. Compression due to thickening of the bicipital aponeurosis, the aponeurosis crosses from the lateral to medial over the antecubital fossa and may irritate the median nerve.
. Compression of the nerve from the fibrous arch of the origin of the flexor digitarum superficialis (FDS).
The median nerve runs dowen the medial side of the arm and passes 2 ½ to 4 cm below the level of the medial epicondyle before it enters between the two heads of the pronator teres.
About 1% of patients have a medial supracondylar humeral spur about 5 cm proximally to the medial epicondyle.
The ligament of struthers is attached to this bony projection which connects the process to the medial epicondyle.
The bony process points towards the elbow joint.
The median nerve can become compressed by the supracondylar spur.
The median nerve can also become trapped by the ligament of struthers that extends from the supracondylar process to the medial epicondyle.
The ligament of struthers is different from the arcade of struthers, which deals with compression of ulnar nerve around the elbow.
Clinical presentation:
Paresthesia in the lateral 3 ½ fingers may occur with compression of median nerve at the elbow region or at the carpal tunnel region.
Symptoms are similar to the carpal tunnel syndrome but are worst with rotation of the forearm.
Patient will complain of dull aching pain over the proximal forearm with no night time symptoms.
The pain is usually worsened by repetitive or forceful pronation.
Tenderness of palpation to the pronator teres muscle.
The median nerve gives off a palmar cutaneous branch before entering the carpal tunnel.
Sensory disturbances over the palm of the hand occur due to involvement of the palmar cutaneous branch of the medial nerve and this occurs proximal to the carpal tunnel.
This differentiates between the carpal tunnel syndrome and the pronator teres syndrome.
Examination Tests:
There are specific provocative tests that produce the pain and distal paresthesia are used to localize the site of compression.
Tinel’s sign at the wrist will be negative.
Phalen’s test will be negative.
Median nerve compression tests are negative at the carpal tunnel; however there will be a positive Tine’s sign at the proximal forearm.
When compression of the nerve involves the supracondylar process, the test is considered positive if symptoms of tingling worsen while tapping on the spur.
Occasionally the spur can be felt.
The pronator teres muscle can be assessed as the cause of the median nerve compression in different ways.
Resisted forearm pronation with elbow flexion will test for compression at the two heads of the pronator teres muscle.
The patient’s forearm is held in resisted pronation and flexion.
While remaining in a pronated position the forearm is gradually extended.
Compression of the median nerve can also be tested by:
- Resisted elbow flexion with forearm supination (compression at the bicipital aponeurosis).
- Resisted contraction of the FDS to the middle finger (compression at the FDS arch).
Differential Diagnosis:
- C6/C7 Radiculopathy; involvement of the nerves at these levels will cause numbness of the thumb, index and long fingers, as well as weakness of the muscles of the forearm that are innervated by the median nerve.
The radial nerve part of C6- C7 will show normal function of the wrist extensors and the triceps.
- Carpal Tunnel Syndrome.
X-rays, imaging and nerve conduction studies may be helpful in the diagnosis.
Treatment:
. Rest.
. Splint.
. NSAIDs.
Surgical decompression of the median nerve through all 4 or 5 possible sites of compression when non-operative management fails for 3-6 month.
The results of surgery are variable, full recovery is not always seen in all patients.
About 80% of the patients improve with surgery.
The skin incision may leave an unsatisfactory scar.

Physical Therapy should be listed as a treatment option!

[@Touichii]

Occupational therapy as wel

[@Tobias27_]

Such a great tutorial video, thanks to all my heart. Your channel deserves a lot more recognition. Sincerely yours, love from Turkey 🇹🇷

[@muhammadebad7778]

Easy clear simple and best illustrated.. Thanks

[@TheStefanzo69]

Brilliant. Concise, informative, to the point! More for practitioners that the general public

[@STIPOWER97]

after 4 years and 3 different doctors not making sense and leaving me feeling lost i think ive finally discovered what is wrong with me,it all make sense

[@vicachcoup]

Brilliant presentation.

[@yutverg6109]

This Nabil must be a holy man, to do so human and friendly videos.

[@briantheprion]

These series are great but the sudden voice at the end always gets me.

Awesome. Thanks professor for helping us orthopedic surgeons with exam preparation. May ALLAH give your success ameen.

[@parveensiddique1251]

wonderful !very informative.

[@Deerector]

Great video. Thanks doc

[@marcballard556]

This is very informative. I had a bicep rupture and surgery one year ago and still don't have full sensation in my thumb, index and middle fingers. My upper forearm is also partially numb. My ortho doctor has suggested pronator teres syndrome as possibility. Have you ever heard of this following a bicep surgery?

[@jamesa.pavlovlmt]

Love your videos please keep it up. you got your self a fan.

[@olesjasako2008]

A nice video!

[@TheOriginalMarimoChan]

Thank you this was very helpful.

good presentation

[@rezabaclass10]

thanks and be careful to every one

[@chinafox1]

great video!

[@geojor]

good one, thank you...

[@martwells786]

My pronator teres hurts from arm wrestling

[@jikeme90]

very thanks for schematic presentationthere is mistake at 0:42' principle symptom > principal symptomin my opinion,pronator teres injection(by lidocaine and/or triam)is comparable with operation at efficency and results

excellent

[@mohsinishfaq2554]

You are the best 👍👍👍

[@migrane76]

Can it be bilateral, or would that be more likely due to double crush syndrome?

[@mehmetkar1234]

thanks a lot

[@gamaltaher9714]

Good, thanks

[@jisooharid]

Thanks a lot!

[@johnsarab4500]

'Dr, it hurts when I do this'. Dr., 'Then do that". But if repetitive, stressful motion is the likely cause, then avoid that motion.

[@thomasflynn642]

I tore my forecept muscle! can you fix it?

[@IncognitosRandom]

My pain is more towards that muscle on the top of the forearm. Is that still the same issue or something different? Thanks.

[@MrBangla11]

Where to find treatment for this?

[@HILUXCHAINSAW]

Good vid but....Turn the music off!!!.

[@levibowman3262]

My only hope is surgery that is known to "improve" the situation in 89 percent of cases. While also leaving a scar. Oh well my depression is kicking in.

[@fernandomanrique5406]

I loved the video but I gave a negative review because the Treatment you show doesn't include Physical Therapy.
