Minimally invasive tenotomy of the tibial insertion of the semitendinosus muscle: An ex vivo study in horses.

Abstract: To describe a minimally invasive technique for semitendinosus tenotomy with ultrasonographic guidance and to evaluate procedural complications. Methods: Experimental study. Methods: Cadaveric equine hind limbs (n = 16). Methods: A stab incision was performed distocaudal to the tibial insertion of the semitendinosus muscle with ultrasonographic assistance. After transection of the tendon with an arthroscopic retrograde knife, the tendon edges palpably retracted, and complete transection was confirmed by ultrasound. Limbs were dissected to confirm the degree of tendon transection and to identify iatrogenic trauma to surrounding soft tissues. Results: Tenotomy was complete in all limbs, resulting in a palpable gap forming between tendon edges. Superficial iatrogenic laceration to the underlying gracilis muscle (n = 2) or gracilis fascia (n = 1) was apparent in 3 of 16 limbs. Conclusions: Ultrasound-assisted tenotomy of the tibial insertion of the semitendinosus muscle was reliably performed in a minimally invasive fashion with minor iatrogenic damage. Conclusions: Minimally invasive tenotomy of the semitendinosus muscle can be performed with ultrasonographic assistance and should be considered as an alternative technique for surgical management of fibrotic semitendinosus myopathy.

The research article is about a minimally invasive method to perform the tenotomy (surgical cutting) of the semitendinosus muscle in horses using ultrasound guidance. The article tests this procedure on cadaveric horse limbs and studies the complications or damage arising from it.

Objective and Methodology

  • The aim of the study was to describe and assess a minimally invasive technique to perform the tenotomy of the tibial insertion of the semitendinosus muscle in horses.
  • The researchers adopted an experimental approach to conduct this study.
  • The subject matter of their tests were cadaveric hindlimbs of horses (total 16).
  • The process involved making a small incision at a spot distocaudal (behind and below) to where the semitendinosus muscle inserts into the tibia (shin bone), under ultrasonographic guidance.
  • They then performed a transection (cutting or division), of the tendon using an arthroscopic retrograde knife and verified that the transection was complete through palpation and ultrasound.
  • Further, the dissected limbs were examined to confirm the degree of tendon transection and to identify any iatrogenic (caused by medical treatment or procedures) trauma to the surrounding soft tissues.

Results

  • The research found that the tenotomy procedure was successfully completed in all the limbs, and resulted in a palpable gap between the tendon edges.
  • Minor iatrogenic damage was observed in 3 of the 16 limbs – 2 limbs showed a superficial iatrogenic laceration to the underlying gracilis muscle, and 1 of them showed similar laceration to the gracilis fascia.

Conclusion

  • This study concluded that the minimally invasive tenotomy of the semitendinosus muscle can be reliably performed with the help of ultrasound guidance.
  • While minor iatrogenic damage is a risk, the benefits of this surgical procedure make it a viable alternative for treating fibrotic semitendinosus myopathy – a disease affecting the semitendinosus muscle that results in loss of its ability to stretch.
