Surgical reconstruction for severe acromioclavicular joint separation using a synthetic loop technique provides excellent outcomes. Most athletes return to normal activities within six months post-operation.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Traumatology

Background:

  • Acromioclavicular (AC) joint separation is a common shoulder injury, particularly in athletes.
  • High-grade AC joint separations (grades III-V) often require surgical intervention for optimal recovery and return to function.
  • Previous surgical techniques have had limitations in achieving anatomical reduction and stability.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of a specific synthetic loop technique for surgical reconstruction of severe acromioclavicular joint separations.
  • To assess patient satisfaction and functional recovery following this surgical approach.

Main Methods:

  • A cohort of 14 patients with grade III, IV, or V AC joint separations underwent surgical reconstruction using a synthetic loop passed through the coracoid and clavicle.

Related Experiment Videos

  • Patients were followed for an average of 44.2 months post-surgery.
  • Functional outcomes were assessed using the University of California, Los Angeles (UCLA) rating scale.

    • Main Results:

    • Twelve out of 14 patients (85.7%) achieved good or excellent results, returning to normal sport and work activities by 6 months.
    • Two patients initially had poor results; one required revision due to noncompliance, and the other needed manipulation under anesthesia.
    • Both revision cases ultimately achieved good or excellent outcomes at the 2-year follow-up.

    Conclusions:

    • Fixation of the clavicle to the coracoid using the described synthetic loop technique is a safe and effective method for treating severe AC joint separations.
    • This surgical approach yields satisfactory results, enabling a return to pre-injury activity levels in an athletic population.
    • The technique offers anatomical reduction and stability, addressing limitations of simpler fixation methods.
