Background:
Trapezius palsy can occur due to traumatic or idiopathic spinal accessory nerve injury. As a result of trapezius palsy, shoulder girdle imbalance can develop and present as lateral scapular winging and diminished shoulder range of motion and function. The modified Eden-Lange triple-tendon transfer procedure is a notable salvage operation which can treat chronic trapezius palsy after failure of conservative and nonsalvage interventions.
Indications:
A 42-year-old right-hand dominant woman who underwent a cervical lymph node biopsy 3 years before presents with chronic left shoulder weakness, severe shoulder pain, and scapular winging. On presentation, she has failed conservative treatments and operative interventions including attempted spinal accessory nerve exploration and repair with ansa cervicalis autograft.
Technique Description:
A modified Eden-Lange triple-tendon transfer, using the Elhassan modification, was performed to treat the patient's chronic trapezius palsy. The levator scapulae, rhomboid minor, and rhomboid major were sequentially transferred to the lateral scapular spine, central scapular spine, and medial scapular spine, respectively.
Results:
At interval follow-up, the patient was recovering well from her operation and with progressively improving range of motion and strength.
Discussion/Conclusion:
The modified Eden-Lange triple-tendon transfer technique is a salvage procedure for treating chronic trapezius palsy by anatomically reconstructing the force vectors of the native trapezius muscle. Effective restoration of proper scapular and shoulder kinematics via the triple-tendon transfer technique can result in improved pain and shoulder girdle function.The author(s) attests that consent has been obtained from any patient(s) appearing in this publication.
