About this study
This study is a prospective single-arm surgical protocol evaluating biceps-to-flexor digitorum superficialis (FDS) tendon transfer using a tensor fascia lata graft for restoration of finger flexion in patients with traumatic pan-brachial plexus injury (pan-BPI). Finger flexion reconstruction in intrinsic-minus hands remains challenging, as conventional flexor digitorum profundus (FDP)-based reconstructions may result in clawing and ineffective grasp. The proposed technique aims to improve metacarpophalangeal and proximal interphalangeal joint flexion to enhance functional grasp. Eligible patients are those with pan-BPI who previously underwent nerve transfer and achieved elbow flexion strength of at least Medical Research Council (MRC) grade 4. Patients with significant joint stiffness, severe forearm soft tissue injury, or insufficient elbow flexion strength are excluded. The procedure consists of staged reconstruction followed by tendon transfer with tensor fascia lata graft interposition. Postoperative management includes 4 weeks of immobilization and progressive rehabilitation. The primary outcome is functional finger flexion, while secondary outcomes include complications and reoperation rates.
Read the detailed description
Traumatic pan-brachial plexus injury (pan-BPI) results in severe upper limb dysfunction, with finger flexion restoration remaining challenging. FDP-based reconstructions often produce clawing and ineffective grasp in intrinsic-minus hands. This study proposes biceps-to-FDS tendon transfer using a tensor fascia lata graft to improve MCP and PIP flexion and enhance grasp. This is a prospective single-arm surgical protocol. Eligible patients include those with pan-BPI who have undergone nerve transfer and achieved elbow flexion at least MRC grade 4. Patients with joint stiffness, severe forearm soft tissue injury, or inadequate elbow strength are excluded. The procedure involves staged reconstruction, followed by tendon transfer with graft interposition. Postoperatively, immobilization is maintained for 4 weeks, with gradual rehabilitation. Primary outcome is functional finger flexion. Secondary outcomes include complications and reoperation.

Biceps to FDS tendon transferProcedure or surgery
All procedures were performed under general anesthesia. An S-shaped incision was made over the anterior elbow to identify and mobilize the biceps tendon to its insertion at the radial tuberosity, followed by division of the bicipital aponeurosis. A second incision was made in the distal forearm to identify the flexor digitorum superficialis (FDS) tendon. The tendon gap was measured to determine graft length. A tensor fascia lata graft was harvested from the lateral thigh, tubularized, and used as an interposition tendon graft. The graft was attached to the biceps tendon using the Pulvertaft technique with nonabsorbable sutures, then passed through a subfascial tunnel to the distal forearm to prevent bowstringing. With the elbow flexed at 90° and fingers in full flexion, the distal graft was woven into the FDS tendons using the Pulvertaft technique. Transfer tension was confirmed by assessing the tenodesis effect.
| Study group | Role | What they receive |
|---|---|---|
| Biceps to FDS transfer | Experimental | Patients with traumatic pan-brachial plexus injury without spontaneous recovery underwent staged reconstruction to restore upper extremity function. Initial nerve transfer procedures included phrenic nerve transfer to the suprascapular nerve for shoulder stabilization and spinal accessory or intercostal nerve transfer to the musculocutaneous nerve or motor branch to the biceps for elbow flexion restoration. Secondary procedures, including wrist arthrodesis and first carpometacarpal joint fusion, were performed to optimize hand positioning for grasp. After patient selection, those with elbow flexion strength of at least Medical Research Council (MRC) grade 4 underwent biceps-to-flexor digitorum superficialis (FDS) tendon transfer using tensor fascia lata as an interposition tendon graft. Patients with finger joint stiffness, severe forearm soft tissue injury, or elbow flexion strength less than MRC grade 4 were excluded. Receives: Procedure: Biceps to FDS tendon transfer |
What is being measured
The primary outcome is the main question the study is designed to answer.
Finger flexion motor power
Finger flexion motor power was assessed using the Medical Research Council (MRC) grading system at postoperative follow-up visits for a minimum of 3 months after surgery. Motor strength was graded on a scale from M0 to M5, where M0 indicates no visible muscle contraction and M5 indicates normal muscle strength against full resistance. Functional finger flexion strength during grasp was evaluated clinically by the treating surgeon.
Measured: From enrollment to at least 3 months after surgery
Secondary outcomes (3)
Elbow flexion motor power
Elbow flexion motor power was assessed using the Medical Research Council (MRC) grading system at postoperative follow-up visits for a minimum of 3 months after surgery. Motor strength was graded on a scale from M0 to M5, where M0 indicates no visible muscle contraction and M5 indicates normal muscle strength against full resistance. Elbow flexion strength was evaluated clinically by the treating surgeon.
Measured: From enrollment to at least 3 months after surgery
Tendon rupture
Tendon rupture was assessed as a postoperative complication during follow-up visits for a minimum of 3 months after surgery. Tendon rupture was diagnosed clinically based on loss of active finger flexion or loss of previously achieved motor function at the tendon transfer site, with additional imaging performed when clinically indicated. The incidence of tendon rupture and the need for reoperation were recorded.
Measured: From enrollment to at least 3 months after surgery
Finger stiffness
Finger stiffness related to excessive tension of the tendon transfer was assessed as a postoperative complication during follow-up visits for a minimum of 3 months after surgery. The complication was defined as limitation of passive and/or active finger motion associated with excessive tightness of the tendon transfer, resulting in impaired hand opening or functional finger movement. Clinical evaluation was performed by the treating surgeon, and the incidence of stiffness and requirement for additional intervention were recorded.
Measured: From enrollment to at least 3 months after surgery

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study is a prospective single-arm surgical protocol evaluating biceps-to-flexor digitorum superficialis (FDS) tendon transfer using a tensor fascia lata graft for restoration of finger flexion in patients with traumatic pan-brachial plexus injury (pan-BPI). Finger flexion reconstruction in intrinsic-minus hands remains challenging, as conventional flexor digitorum profundus (FDP)-based reconstructions may result in clawing and ineffective grasp. The proposed technique aims to improve metacarpophalangeal and proximal interphalangeal joint flexion to enhance functional grasp. Eligible patients are those with pan-BPI who previously underwent nerve transfer and achieved elbow flexion strength of at least Medical Research Council (MRC) grade 4. Patients with significant joint stiffness, severe forearm soft tissue injury, or insufficient elbow flexion strength are excluded. The procedure consists of staged reconstruction followed by tendon transfer with tensor fascia lata graft interposition. Postoperative management includes 4 weeks of immobilization and progressive rehabilitation. The primary outcome is functional finger flexion, while secondary outcomes include complications and reoperation rates.
