FAQ: Flexor Tendon Injury

Depending on the location of the injury, the mechanism of your injury and age of injury, you may need a surgical correction or pinning of the finger to help restore function to the injured hand/finger.

This surgery attempts to bring the two ends of the ruptured/cut tendon back together in hopes that it can restore the function and dexterity in the finger.

Typical risks associated with this surgery is injury to nerves, arteries or and or nearby structures. Additional risks include wound infections in the hand.

Non-surgical options include splinting or casting of the injured hand/finger depending on the type and complexity of injury. If the tendon rupture includes a fracture of a carpal bone and there is instability of the fracture or dislocation, your surgeon may elect to have your hand placed into a cast after realignment with further splinting if appropriate.

Depending on the location of the flexor tendon injured different surgical techniques are applied to repair the injured tendon and help restore the function lost due to the tendon injury. Other surgical repairs may include a tendon transfer to help facilitate function or tendon graft if the ends of the injured tendon cannot be approximated. Tendon grafts are harvested from another tendon in the arm or from the ankle (palmaris longus and plantaris tendon respectively).


If you chose not to have any management for an flexor tendon injury, it is likely that you have sustained loss of function as well as anatomical deformity in the finger/hand injured.





Immediately after surgery, you will be placed in a cast to protect the repair. This cast may stay on for 4 weeks. Afterwards, depending on the injury, you will either be placed into a dynamic splint or may need serial splinting in order to slowly introduce motion to the injured joint. In the long term, with physiotherapy and stretching, the range of motion and strength of the joint for most patients improve to about 80% of their previous function

Symptoms may reoccur if you re-injure the hand or cause a second rupture. As the strength of the tendon is now weaker. The exact reoccurrence rate is unknown

The incision will likely be above the region of the rupture tendon and can range in length depending on the amount of tendon retraction there is from initial injury.




You will likely need to be casted after surgery for 4-6 weeks. Depending on the complexity of injury, it may be appropriate after a couple weeks for you to be placed into a splint for serial splinting (to progressively change the degree support you require) or placed into a dynamic splint.

Pain after surgery can vary depending on the complexity of the injury and surgical repair.

We usually recommend you to take Acetaminophen (Tylenol) and/or ibuprofen (Advil/Motrin) after surgery. You may need some prescription pain medication which will be prescribed for you after surgery.

Usually, there is no tubes or drains placed after surgery if the repair is in the hand. Larger and more extensive repairs in the arm may require a drain placement. The drain is usually left in place for 2-3 days.

You will need physical therapy after surgery, as this is the most essential part to the recovery process. Physical therapy session will start after the cast is removed and you may need several sessions for the following weeks to month of surgery.

You likely will not need any crutches/boots after surgery, unless the repair is in your leg.

Usually, this is an outpatient procedure and you will not need to stay in the hospital. However, if the surgery is extensive, you may need to stay overnight.

The repaired tendon usually be back to full strength about 12 weeks, but it up to six months to regain the full range of movement. In some cases, it may never be possible to move the affected finger or thumb as much as before it was damaged.

Will put in the cast, your arm is protected for further injury, but it is recommended that you stay away from contact sports and water activities. After your cast is removed and you begin to regain strength, your level of activity will be modified

Depending on the injury and repair, some patients are able to drive. However, with the cast on, some individuals find it cumbersome and difficult to drive safely. Additionally, it is recommended that you do not drive while taking any prescription pain medication.

Most patients will take a week off work, but some people elect to return to work prior to that. If your cast does not interfere with your work, you can return to work 1-2 days after your surgery. However, if your workplace requires significant manual dexterity, you might need to modify the work you do during the recovery process.

If your procedure is an outpatient procedure performed in the ambulatory clinic, you will be receiving local anesthetics to numb/block sensation in the hand for a short duration. However, if your repair is extensive and it is done in the operative room, you may need general anesthesia where you a put to sleep.

If your procedure is complex and requires general anesthesia, you will need to see an anesthesiologist for evaluation prior to surgery.

Your medication list will be reviewed prior to surgery. However, you should also review your medication with your family doctor as well.

Generally, blood thinners should be stopped prior to surgery. However, different types of blood thinners should be stopped for different durations prior to surgery. Your family physician should be consulted as to when and if you should stop your medication prior to surgery.

Typically no other tests is required prior to surgery as trigger finger is diagnosed by symptoms experienced by the patient. However, certain individuals on specific types of blood thinners may need a blood test immediately prior to surgery.

If you are scheduled for surgery in the ambulatory clinic, there are no diet and fluid restrictions prior to or after surgery

However, if your surgery is scheduled to be in the operating room and you’ll seen anesthesiologist for general anesthesia, you will need to stop eating/drinking at midnight the evening prior to your surgery.

You can shower with antibacterial soap the evening prior to or the morning of your surgery. This is only needed if your surgery is scheduled to happen in the operating room.

If you are having surgery in the surgical clinic, you should arrive at your appointment time for surgery.

If you are scheduled to have surgery in the operating room, there should be an appointed time for you to arrive in your information package given to you during your consultation with the anesthesiologist.

Please call the office at (416)222-6986 to see your scheduled date and time for your surgery. This surgery is usually performed at two different hospital sites: Mackenzie Health Center or Rouge Valley Centenary Hospital. Once your appointment is set, you will be directed to the correct site.

You will likely need someone to drive you home after surgery as driving with a cast maybe cumbersome at first and require some time before you get used to having the cast on your hand.

This is usually the same case for patients who have their procedure in the operating room and are discharged the same day of surgery. However, you if you stay in the hospital after surgery and/or if you are unable to mobilize after surgery, we may give you some blood thinners to prevent the formation of blood clots after surgery.

For procedures done under local anesthetics, no antibiotics is needed for surgery. If you require general anesthesia, we generally give one dose of antibiotics prior to surgery. You will not need antibiotics after surgery.

Injuries to flexor tendons (tendons on the palm and palmar aspect of the arm) often results from cuts or when there is significant jamming force hitting the fingers causing the tendons to rip or rupture from their bony attachment. This leads to functional impairments as well as anatomic deformities.

Flexor tendons are tendons run on the palmar side of your arm down the palm of the your hand and fingers. They function to bend/flex the wrist, fingers and thumb to allow your to grasp things and make a fist.



What are the different methods of treating flexor tendon injuries?
There are multiple ways to treat an flexor tendon injury depending on the age of the injury, mechanism of injury and the location of the injury.

Splinting – the injured finger is placed into a splint to straighten the finger and allow the ruptured tendon to scar down and restore the function of the finger

Surgical repair – when the end opposing ends of the cut/ruptured tendon is brought back together and sutured. After surgical repair, you often need to placed into a cast to protect the surgical repair.
