Ex vivo evaluation of an alternative technique for resection of the proximal manica flexoria in horses.

Abstract: To describe and evaluate an alternative technique for tenoscopic resection of the manica flexoria (MF). Methods: Descriptive study. Methods: Equine cadaver forelimbs and hind limbs (n = 36). Methods: Three surgeons varying in experience resected the MF in 12 limbs. The procedure was divided into six steps, including resection of the lateral/medial borders of the MF with a hook knife and resection of the proximal border with a micro scalpel. Outcomes compared between surgeons included completeness of resection, appearance of the margins of resection, appearance of the resected MF, collateral damage, and time required for resection. Results: The MF was successfully resected in all specimens, with a median time of 14 minutes 54 seconds (range, 6 minutes 42 seconds to 43 minutes 33 seconds). Nineteen of 36 MF were categorized as symmetric, 11 of 36 MF were categorized as mildly asymmetrical, and six of 36 MF had unequal borders. No differences were detected between surgeons regarding the appearance of the MF and number of iatrogenic lesions. Five lesions were considered potentially clinically relevant; three were caused by the arthroscope in the scutum (1) and the deep digital flexor tendon (DDFT; 2), and two consisted of DDFT damage caused by the microscalpel. Conclusions: The MF was successfully and symmetrically resected with minimal damage to adjacent structures by surgeons with varying levels of experience. Conclusions: The results of this study provide evidence to justify further evaluation of the technique described here in live horses with rupture of the MF.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research paper discusses an alternative method for surgical removal (resection) of a part of the equine tendon system (manica flexoria) using equine cadaver limbs. The study measures outcomes such as completeness of removal, condition of the remaining tissue, and time taken for the procedure among surgeons of varying experience levels.

Experimental Methodology

  • The experiment was carried out on 36 cadaver limbs of horses.
  • Three surgeons with differing levels of experience performed the resection of the manica flexoria (MF) in 12 limbs each.
  • The surgery technique was bifurcated into six primary steps including resection of the lateral/medial borders of the MF using a hook knife, followed by the resection of the proximal border with a micro scalpel.
  • Outcome factors considered for comparison included completeness of resection, the appearance of the edges of the resected area, the appearance of the removed MF, any peripheral damage, and the time required for the resection procedure.

Results and Observations

  • Every limb saw successful resection of the MF, with a median duration of 14 minutes and 54 seconds, the fastest being 6 minutes and 42 seconds and the longest taking 43 minutes and 33 seconds.
  • Of the 36 resected MF, 19 were classified as symmetric, 11 as mildly asymmetrical, and 6 had unequal borders.
  • No significant differences were observed among the surgeons with regard to the MF’s appearance and the number of lesions caused by the surgery (iatrogenic lesions).
  • Among the lesions caused by the procedure, five were identified as potentially clinically significant; three were caused by the arthroscope in the scutum and the deep digital flexor tendon (DDFT), and two were caused by the microscalpel damaging the DDFT.

Conclusions

  • The manica flexoria (MF) was successfully and symmetrically resected with minimal damage to nearby structures by surgeons across different experience levels.
  • The positive results from this study justify additional examination of the described technique, this time in live horses that have experienced a rupture of the MF.
