Abstract The purpose of this study was to determine the feasibility and clinical benefits of using 3D-printed hemipelvis models for periacetabular osteotomy preoperative planning in the treatment of hip dysplasia. This retrospective study included 28 consecutive cases in 26 patients, with two bilateral cases, who underwent periacetabular osteotomy between January 2017 and February 2020 and had routine radiographs, CT and MR imaging. Of these, 14 cases [mean patient age 30.7 (SD 8.4) years, 11 female] had routine preoperative imaging, and 14 cases [mean patient age 28.0 (SD 8.7) years, 13 female] had routine preoperative imaging and creation of a full-scale 3D-printed hemipelvis model from the CT data. The expected surgical cuts were performed on the 3D-printed models. All patients underwent Bernese periacetabular osteotomy. Operative times, including time to achieve proper acetabular position and total periacetabular osteotomy time, fluoroscopy radiation dose and estimated total blood loss were compiled. ANOVA compared outcome variables between the two patient groups, controlling for possible confounders. On average, patients who had additional preoperative planning using the 3D-printed model had a 5.5-min reduction in time to achieve proper acetabular position and a 14.5-min reduction in total periacetabular osteotomy time; however, these changes were not statistically significant (P = 0.526 and 0.151, respectively). No significant difference was identified in fluoroscopy radiation dose or total blood loss. Detailed surgical planning for periacetabular osteotomy using 3D-printed models is feasible using widely available and affordable technology and shows promise to improve surgical efficiency.

Purpose: The aim is to describe the main characteristics of an anterior/posterior segment surgery and how to resolve intraoperative complications. Setting/Venue: The anterior and posterior segment surgical video was created at the Department of Ophthalmology, Virgin Macarena University Hospital, Seville, Spain. Methods: We present the case of a male with Stevens-Johnson syndrome and severe limbal deficiency who needed a Boston type 1 keratoprosthesis, reaching a visual acuity of 0.4 (0.05 before surgery). In the course of follow-up, he developed corneal melting with perforation, immune vitritis, and a large epimacular membrane. We decided to perform a 23-gauge vitrectomy associated with keratoprosthesis exchange. As a consequence of inappropriate anesthesia, the patient woke up during the surgery, provoking a retinal tear besides a choroidal detachment. These damages needed endolaser photocoagulation as well as silicone oil tamponade, forcing us to postpone the exchange. An intravitreal dexamethasone implant was also injected. Two months later, the silicone oil was removed, and the Boston keratoprosthesis was replaced by a new type 1 model with a titanium back plate, which likely improves biocompatibility and retention and may reduce complications such as retroprosthetic membranes and stromal corneal melts. Results: Good anatomical results were achieved, and visual acuity slightly improved to 0.2. Conclusions: Combined anterior and posterior segment surgery represents a great challenge that can improve not only visual acuity but also quality of life in patients with severe diseases such as Stevens-Johnson syndrome.
