| Sumario: | Dr. W. Thiel developed a human cadaver preservation technique that maintains essential featuressuch as tissue flexibility, elasticity, volume, and color, using minimal amounts of formaldehyde. This methodenables clear anatomical recognition without significant alterations in the preserved material. The aim ofthis study was to evaluate the application of the CFP-Soft Fix specimen preservation method—a modified,formaldehyde-free version of Thiel’s technique—to the locomotor system of New Zealand rabbits. Twentyrabbits were used. Pelvic members were extracted and preserved. The effectiveness of the modified techniquewas assessed by examining parameters such as joint flexibility, muscle elasticity, muscle volume, tissuecolor, and presence of fungal or bacterial contamination. Additionally, a histological analysis of muscle andtendon tissues was performed. The solution proved to be non-irritating and nearly odorless, while effectivelypreserving color, flexibility, and plasticity, closely resembling live tissue. The preserved specimens exhibitedexcellent joint flexibility, good tissue elasticity, nearly normal muscle volume, and well-preserved histologicalmuscle structure. The CFP–Soft Fix method successfully eliminated formaldehyde from the preservationprocess and demonstrated adaptability for use in domestic animals. This technique allows for safe anatomicalstudy, supports the use of complementary tools such as arthroscopy, laparoscopy, endoscopy, and diagnosticimaging, and reinforces the importance of detailed anatomical knowledge in clinical education by improvingrecognition of topographic structures and spatial relationships. |
