RESUMO

BACKGROUND: Fractures involving the posterior acetabulum with its rich vascular and neural supply present challenges in trauma orthopedics. This study evaluates the effectiveness of 3D printing technology with the use of custom-made metal plates in the treatment of posterior wall and column acetabular fractures. METHODS: A retrospective analysis included 31 patients undergoing surgical fixation for posterior wall and column fractures of the acetabulum (16 in the 3D printing group, utilizing 3D printing for a 1:1 pelvic model and custom-made plates based on preoperative simulation; 15 in the traditional group, using conventional methods). Surgical and instrument operation times, intraoperative fluoroscopy frequency, intraoperative blood loss, fracture reduction quality, fracture healing time, preoperative and 12-month postoperative pain scores (Numeric Rating Scale, NRS), hip joint function at 6 and 12 months (Harris scores), and complications were compared. RESULTS: The surgical and instrument operation times were significantly shorter in the 3D printing group (p < 0.001). The 3D printing group exhibited significantly lower intraoperative fluoroscopy frequency and blood loss (p = 0.001 and p < 0.001, respectively). No significant differences were observed between the two groups in terms of fracture reduction quality, fracture healing time, preoperative pain scores (NRS scores), and 6-month hip joint function (Harris scores) (p > 0.05). However, at 12 months, hip joint function and pain scores were significantly better in the 3D printing group (p < 0.05). Although the incidence of complications was lower in the 3D printing group (18.8% vs. 33.3%), the difference did not reach statistical significance (p = 0.433). CONCLUSION: Combining 3D printing with individualized custom-made metal plates for acetabular posterior wall and column fractures reduces surgery and instrument time, minimizes intraoperative procedures and blood loss, enhancing long-term hip joint function recovery.

RESUMO

BACKGROUND: ue to the lack of consensus on the optimal surgical treatment for distal radius fractures (DRF) in elderly patients over 65 years old, the purpose of this study was to compare the efficacy of external fixation (EF) with Kirschner wires and volar locking plate (VLP) in the treatment of DRF through a retrospective cohort study. We hypothesized that there would be no significant difference in overall complications and functional recovery between the two methods. METHODS: We retrospectively analyzed 62 patients over 65 years old who underwent surgical treatment for C-type DRF between 2019 and 2022. Based on the different treatment methods, they were divided into the EF group and the VLP group. General data, inpatient data, and postoperative complications during follow-up were recorded. The X-ray images before surgery, after surgery, and at the last follow-up were analyzed, and the results of wrist motion range, Gartland-Werley wrist joint score, and DASH score were evaluated 6 months after surgery for both groups. RESULT: Thirty patients underwent closed reduction and external fixation combined with Kirschner wire fixation, while 32 underwent open reduction and VLP fixation. The EF group had significantly shorter operation time, intraoperative blood loss, injury-to-surgery time, and hospital stay compared to the VLP group (all p < 0.001). At the last follow-up, the radiographic parameters (ulnar variance and radial inclination) and wrist joint function (wrist dorsiflexion and forearm supination) were better in the VLP group than in the EF group (p = 0.04, p = 0.01, p = 0.001, p = 0.02, respectively). However, there was no significant difference in overall Gartland-Werley wrist joint score, DASH score, and incidence of postoperative complications between the two groups (p = 0.31, p = 0.25, p = 0.47, respectively). CONCLUSION: For patients aged 65 and above with distal radius fractures (DRF) of type C, VLP and external fixation with Kirschner wires yield comparable functional outcome and complications rate at the short term. However, VLP allowed restoration of better radiological parameters.
