TENDON REPAIR. TIME-CRITICAL SURGERY.

Flexor & Extensor Tendon Injuries

Tendons that flex or straighten the fingers can snap or be cut in an instant. The sooner they are repaired, the better the chances of a full functional recovery. Do not wait.

ABOUT THIS INJURY

When a Tendon Snaps, Every Hour Counts

Flexor tendons curl the fingers toward the palm; extensor tendons straighten them. Either can be injured through lacerations to the wrist, forearm, palm or fingers, through forceful trauma in sport or accidents, or through spontaneous rupture in patients with rheumatoid arthritis where weakened tissue is more prone to tearing.

The most common presentation is a cut to the hand, often one that looks minor, that severs one or more tendons. The result is a finger that will not bend or straighten. Surgery needs to be performed as soon as possible: delayed presentation significantly complicates repair and may require a more involved two-stage reconstruction.

The procedure involves exploring the wound, locating the cut ends of the tendon and repairing them with specialised stitching techniques. When the injury is presented late and direct repair is no longer possible, a two-stage repair using silicone rods may be required. Post-operative splinting and a strict physiotherapy protocol are just as important. Without them, even well-performed surgery will not give a good functional result.

DON'T WAIT ON A TENDON INJURY

The Cost of Delaying Surgery

A tendon injury that is treated within days has a fundamentally better prognosis than one treated weeks later. As time passes after the injury, the cut ends of the tendon retract, scar and contract, making a clean, direct repair progressively harder or eventually impossible. The following outcomes become increasingly likely with every day of delay.

  • !Retracted tendon ends that can no longer be brought together directly
  • !Scarring and adhesions within the tendon sheath that resist repair
  • !Need for a more complex two-stage reconstruction instead of a single direct repair
  • !Longer overall recovery and a lower ceiling for functional outcome
  • !Permanent limitation of finger movement if the injury is left without any treatment

RECOVERY TIMELINE

What Recovery Looks Like Week by Week

Week 1

Surgery & Wound Review

The tendon is repaired and a protective splint fitted. A follow-up appointment within the first week checks wound healing and initiates physiotherapy referral.

Weeks 2–4

Controlled Mobilisation

Guided range-of-motion exercises begin under physiotherapy supervision. The splint remains in place. Compliance with the protocol at this stage is critical to prevent adhesions forming around the repaired tendon.

Weeks 4–8

Intensive Physiotherapy

The splint continues to six to eight weeks. Physiotherapy intensifies with progressive strengthening exercises. Return to light work may be possible during this phase depending on the nature of your job.

Weeks 8–12

Strengthening & Work Return

Splint is discontinued. A graduated return to moderate physical work is typically achievable at eight to twelve weeks. Heavier manual activities follow as strength and range of motion are consolidated.

EXPECTED OUTCOMES

What a Successful Repair Can Achieve

With prompt surgery and disciplined rehabilitation, the majority of patients achieve a high level of functional recovery in the repaired fingers.

  • Restored ability to flex or extend the injured fingers
  • Full or near-full range of motion with diligent physiotherapy
  • Prevention of tendon adhesions and long-term stiffness
  • Return to light work within eight weeks in most cases
  • Return to moderate physical work at eight to twelve weeks
  • Best outcomes consistently achieved with early surgery and strict adherence to rehabilitation

WHY CHOOSE PROFESSOR HINDOCHA

Specialist Upper Limb Expertise When It Matters Most

Urgent Surgical Access

Tendon injuries deteriorate with every passing day. Professor Hindocha prioritises prompt assessment and surgical intervention to give the repaired tendon the best chance of healing correctly.

Advanced Repair Techniques

Specialised multi-strand stitching techniques are used to repair the tendon ends with sufficient strength to withstand early mobilisation, an approach linked with better functional outcomes.

Two-Stage Reconstruction When Required

When a tendon injury is presented late and direct repair is no longer possible, a staged silicone rod reconstruction can restore function. It is a more complex procedure, planned with the same care.

Integrated Rehabilitation Protocol

Surgery alone does not guarantee a good result. A structured physiotherapy programme, running alongside your recovery from day one, is an essential part of how we approach every tendon repair.

CHOOSING THE RIGHT TECHNIQUE

Three Approaches to Tendon Repair

The surgical approach is determined by how quickly you seek treatment and the nature of your injury.

BEST OUTCOME

Primary Repair

Performed within days of the injury. The cut tendon ends are located and sutured directly back together using multi-strand repair techniques. Early mobilisation under physiotherapy supervision begins within the first week, producing the best long-term range of motion.

STILL DIRECT

Delayed Primary Repair

Where primary repair was not immediately possible because of contamination, swelling or delayed presentation, a direct repair is still achievable within a limited window of several weeks post-injury, before scarring makes this impractical.

LATE PRESENTATION

Two-Stage Reconstruction

For injuries presenting too late for direct repair, a silicone rod is first placed to form a smooth tunnel in the tendon sheath. Months later, the rod is replaced with a tendon graft. A longer process, but function can still be meaningfully restored.

DO YOU NEED TENDON REPAIR?

When Surgery Is the Right Step

If you cannot fully bend or straighten a finger following an injury, you may have a tendon injury that requires surgical repair. Common presentations include:

  • Inability to bend one or more fingers following a cut or laceration
  • Inability to fully straighten a finger after trauma or injury
  • Recent laceration to the wrist, forearm, palm or fingers
  • Sporting or accident injury with suspected forceful tendon avulsion
  • Rheumatoid arthritis with sudden loss of finger movement
  • Late-presenting injury where the wound has healed but function has not returned

REHABILITATION IS NON-NEGOTIABLE

Splint & Physiotherapy: Why Both Matter

Tendon repair surgery creates a join that is mechanically sound, but that join needs to be protected from excessive force while it heals, and mobilised carefully to prevent adhesions forming around it. This is a fine balance that only a specialist hand physiotherapist can manage correctly.

Too much immobility allows scar tissue to bind the tendon to the surrounding sheath, dramatically reducing range of motion. Too much force risks re-rupture. The protocol is precise and non-negotiable. Strict adherence is the single biggest factor in your final outcome beyond the surgery itself.

  • ✓Wear your splint continuously for the full six to eight weeks, with no exceptions
  • ✓Attend every physiotherapy session, as early mobilisation exercises begin in week one
  • ✓Perform your home exercise programme exactly as instructed, twice daily
  • ✓Never attempt to forcefully straighten or curl the finger against resistance outside sessions
  • ✓Report any sudden loss of movement immediately, as it may indicate tendon re-rupture
  • ✓Strengthening exercises begin only once your physiotherapist confirms the repair is solid

FREQUENTLY ASKED QUESTIONS

Answers About Tendon Injury & Repair

The questions patients and families ask most often.

Flexor tendons run along the palm side of the fingers and hand, pulling the fingers into a curled position when contracted. Extensor tendons run along the back of the hand and straighten the fingers. Either type can be partially or fully cut by a laceration, avulsed from the bone by forceful trauma, or ruptured spontaneously in conditions such as rheumatoid arthritis.
After a tendon is cut, the two ends retract apart and can become scarred in their retracted positions. The longer the delay, the more difficult (and sometimes impossible) it is to bring the ends together for a direct repair. Injuries presenting more than a few weeks after the original event may require a staged two-part reconstruction, which is more complex and carries a longer recovery.
The wound is explored under anaesthesia to locate both cut ends of the tendon. These are then brought together and repaired using specialised multi-strand suturing techniques designed to be strong enough to allow early controlled movement in physiotherapy. Where skin or tendon tissue is missing, grafting may also be required.
When an injury is presented late, weeks or months after it occurred, direct repair is often no longer possible. In these cases, a silicone rod is first inserted into the tendon sheath to create a smooth tunnel. Several months later, the rod is replaced with a tendon graft. This two-stage approach is more involved but can still achieve a good functional result.
A protective splint is worn for six to eight weeks. Physiotherapy runs alongside recovery from the first week post-surgery. Return to light work is typically possible within eight weeks; moderate physical work at eight to twelve weeks. Heavier activity follows as strength is consolidated, usually beyond three months.
With early surgery and strict adherence to the physiotherapy protocol, the majority of patients achieve a high degree of functional recovery. Some degree of reduced range of motion compared to the uninjured side is possible, particularly in delayed presentations. Tendon repairs that are mobilised early under physiotherapy guidance consistently produce better outcomes than those kept immobile.
