Surgery simulation teaching based on real reconstruction aid versus traditional surgical live teaching in the acquisition of an adult total hip arthroplasty surgical technique for developmental dysplasia of the hip: a randomized comparative study

Abstract

Background: A simulation and model (SM) teaching aid using 3D printing was developed to improve a training course for total hip arthroplasty of adult developmental dysplasia of the hip (adult DDH-THA). We named this new method Surgery Simulation Teaching based on a Real Reconstruction Aid (RRA-SST). A prospective randomized comparison was performed with the traditional surgical live teaching method to evaluate the training effectiveness of RRA-SST for adult DDH-THA. Methods: Twenty-six trainees, who were already practicing but were not experienced, participated in the study. We randomly divided the trainees into two groups: Group A (n = 13) received RRA-SST and group B (n = 13) received traditional surgical live teaching. A surgery simulation test and a questionnaire were used for evaluation. Next, each group received training with the other teaching method, and then the test and questionnaire were used again for evaluation. Results: After the first test, the RRA-SST method was shown to produce better results than the traditional surgical live teaching method. After the second test, the results showed the training effect in both groups reached the same level, which was level as Group A RRA-SST results. Analysis of the questionnaire results showed that the training effect of RRA-SST was higher than that of traditional surgical live teaching, from multiple perspectives. Conclusions: The use of RRA-SST improved participant performance according to simulation assessment. RRA-SST can be helpful for trainees who are already practicing but not experienced when developing proficiency in adult DDH-THA surgical techniques.

Integrated acetabular prosthesis versus bone grafting in total hip arthroplasty for Crowe type II and III hip dysplasia: a retrospective case–control study

“…According to Crowe et al's classi cation proposed in 1979, DDH is divided into I-IV types based on the degree of femoral head displacement (4). Patients with Crowe type II and III DDH often have a small and shallow acetabulum, and a false acetabulum forms above the true acetabulum after dislocation of the femoral head, with the overlap between the two prone to causing bone defects (5).…”

Three-Dimensional Printing in Orthopedics: Where We Stand and Where We Are Heading

“…Resident physicians and patients considered that the printed model helped them to understand the deformity. Wang et al, ( 5 in turn, evaluated the use of a 3D model in the teaching of total hip arthroplasty in developmental dysplasia. Surgeons were randomized to a group that used traditional the teaching technique and group that used a teaching technique with 3DP model.…”
