Flexor Tendon Anatomy And Injury - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the Anatomy and Injury of the flexor tendons of the fingers.
The ability to flex the fingers consists of a system of flexor muscles in the forearm and their tendons are inserted into the bones of the fingers. A flexor tendon injury can cause loss of flexion (bending) of the fingers or thumb.
Anatomy
•Flexor digitorum profundus tendon : inserted into the ditsla phalanx
•Flexor digitorum superficialis tendon : inserted into the middle phalanx.
These retinacular structures keep the flexor tendons in place during flexion of the fingers. A1,A2,A3,A4. A2 & A4 pulleys are necessary to insure efficient flexion of the fingers.
Flexor tendon injury zones
•Zone I: distal to superficialis insertion
•Zone II: fibroosseous tunnel : A1 pulley to zone I
•Zone III: carpal tunnel to A1 pulley
•Zone IV: carpal tunnel
•Zone V: prxiaml to carpal tunnel
Testing for injury
•Check the integrity of the profundus tendon : Kepp the PIP of the finger extended and see if the patient can flex the DIP.
•Check the integrity of the superficialis tendon: keep the other fingers extended and then see if the patient can flex the PIP joint of the involved finger.
•When multiple slips of the superficialis tendon are cut, identify the tendons properly. The superficialis tendons of the long and ring fingers are volar at the wrist.
Flexor digitorum profundus tendon avulsion (jersey finger)
•75% involving the ring finger
•Minimal clinical symptosm
•Get an x-ray for bony avulsions
Leddy classification
Type I
•Tendon retraction into the palm
•Re-insert the tendon into P3 within 7-10 days to avoid contracture and necrosis of the tendon
•Neglected injuries: DIP arthrodesis, staged reconstruction.
Type II
•Tendon retraction to the PIP level, can be inserted up till 6 weeks.
•May include a small bony fragment
Type III
Large bony fragment blocks proximal retraction FDP at the A4 pulley.

Tore the tendon in my right index finger, had an unsuccessful repair which tore 3 months down the road, so I had a two step surgery where I had a tendon graft done, they inserted a hunters rod into my hand for 3 months then took the tendon from my arm and I’m currently 2 weeks out, keeping up with pt and anyone who’s scared, trust me I was too but as long as you listen to your doctor and physical therapist you should be fine. Best of luck to all of you :)

Good vid... But who was in charge of the music...

Did something to my lower index knuckle and while my whole index finger is swollen and the lower knuckle is bruised and sore, everything seems to be connected. Think I've just sprained it.

Thank you for this video. You've saved me a couple of hours at the hospital getting it checked. Ice and heat will continue x

His voice scared the crap out of me at the end. I wasn't expecting it lol.

I had to get my tendon repaired on my pinky.. Felt so word while the tendon wasnt attached.. Had no control over my pinky until i had surgery. Thank God it All worked out

[ugonalose]

I previously have had a surgery on my finger where the tendon originally was separated in zone 1.... I waited for awhile to get it checked and by the time I did it was in zone 5... I had surgery done and got it fixed but I was younger at the time and naive so I didn't do therapy.... Now (5 years later) I can barely move my finger due to scar tissue... What's the best way to solve this?

[deanslife]

I cant bend my middle finger on my right hand back to the palm independently and it's the same with the index finger and pinky on my left. Is there no way I can strengthen them as the other fingers are compensating for them which leads to the strain I feel when holding something

[nissanzxtt]

Man you scared the crap out of me, calming music then out of nowhere, ALL MY VIDEOS ....LOL

[ZeldaLovers]

i had my surgery last june 15, it was a tendon cut into my middle finger, they put cast into my whole hand for almost 8 weeks. now iam attending therapy for about 2 weeks now because my hand was so weak. iam having difficulties in flexing my five fingers, how long it will takes to go back into normal flexing especially with my middle finger and is it advisable to lift heavy materials...

Hello. I am writing to you from Azerbaijan. They sewed up my ring finger. My finger does not bend. However, it folds and unfolds. 1 year has passed since the incident. Is it possible to restore it with surgery? Please write an answer. I am grateful

[KryssArt]

I cut right at A2 in my pinky I’m so worried because I can’t move my finger and I don’t know if it’s because it was cut or because I cut my tendon

[lahiruedirisuriya]

Docter . My left hand 3 fingers tendons are broken . One and half years ago. So can i prepare back my tendons?? Please give me a advise

[wavyzain]

Amazing animation with great narration

[americasbestmemes]

Can a finger laceration involving tendon heal by it self or does it depend how deep the laceration is because I'm able to move my fingers back and froth and bend them some what 🤔
