Principles of tendon transfers.

Area of Science:

• Orthopedic Surgery
• Reconstructive Surgery
• Hand Surgery

Background:

• Tendon transfers are crucial for restoring functional deficits, particularly grip, in hand surgery.
• These procedures are considered when neurological interventions are contraindicated or unsuccessful in palsy cases.
• A systematic approach is essential for successful functional restoration.

Purpose of the Study:

• To outline the principles and strategy for performing tendon transfers in hand surgery.
• To detail the assessment parameters for paralyzed hands.
• To emphasize the importance of technical principles for reproducible surgical outcomes.

Main Methods:

• Distinguishing between deficient and transferable muscles.
• Classifying palsy type to determine the scope of functional restoration.
• Analyzing hand paralysis using three parameters: deficient segments, mechanical muscle performance, and motor condition (extrinsic/intrinsic).
• Adhering to standardized surgical techniques: exposure, release, fixation, tensioning, and rehabilitation.

Main Results:

• A structured strategy matching available muscles to functional objectives ensures clarity for patients.
• Understanding the mechanical demands of different movements (high vs. low energy) guides transfer selection.
• Consistent application of technical principles leads to predictable and reproducible surgical results.

Conclusions:

• Tendon transfer surgery, when guided by thorough case analysis and strict technical principles, offers reliable restoration of hand function.
• Preoperative clarity regarding objectives and outcomes is achievable through meticulous surgical planning.
• This approach provides a viable solution for improving grip and overall hand function in patients with paralysis.
