    Plating versus Intramedullary Nailing of OTA/AO 43C1 and C2 Intra-articular Distal Tibia Fractures: A Propensity Score and Multivariate Analysis

    OBJECTIVE: To compare rates of reduction loss, nonunion, and infection in intra-articular distal tibia fractures (IADTF) treated with limited open reduction internal fixation and intramedullary nailing (IMN) as compared to open reduction internal fixation with plate and screws (plate fixation [PF]). METHODS: Design: Retrospective review. Setting: Level-I academic trauma center. Patient Selection Criteria: Patients age ≥ 18 with OTA/AO 43C1 and C2 IADTF treated with IMN or PF between 2013-2021. Outcome Measures and Comparisons: Loss of reduction, surgical site infection (SSI), nonunion, and patient-reported outcomes (PROs) were compared for IMN versus PF treatments. RESULTS: One hundred ten patients met the inclusion criteria (IMN 33 and PF 77). There was no loss of reduction found. Seventeen nonunions (15% overall; IMN 4/33 and PF 13/77) and 13 SSIs (12% overall; IMN 2/33 and PF11/77) were identified. Despite several risk factors being identified for nonunion and SSI in bivariate analysis, only open fracture remained significant as a risk factor for both nonunion (odds ratio 0.09 for closed fracture, 95% confidence interval, 0.02–0.56, P = 0.009) and SSI (odds ratio 0.07 for closed fracture, 95% confidence interval, 0.06–0.26, P = 0.012) in the multivariate model. Propensity scoring based on presurgical variables was significantly different between patients who received IMN versus PF (P = 0.03); however, logistic regression incorporating the propensity score revealed no significant association with nonunion and SSI. Adjusting for the propensity score, there remained no association comparing IMN versus PF with nonunion and SSI (P = 0.54 and P = 0.17, respectively). There was also no difference in PROs between IMN and PF (physical function: P = 0.25 and pain interference: P = 0.21). CONCLUSIONS: Overall nonunion and SSI prevalence was 15% and 12%, respectively, in operatively treated OTA/AO 43C1 and C2 IADTF. An open fracture was a significant risk factor for nonunion and SSI. Metaphyseal fixation through IMN or PF did not affect loss of reduction, nonunion, SSI, or PROs. LEVEL OF EVIDENCE: Therapeutic Level III.

    Results of Low Distal Femur Periprosthetic Fractures
    (Wolters Kluwer, 2022-02-28) Virkus, Walter; Lieder, Charles; Jang, Yohan; Rea, Parker; Gaski, Greg; Orthopaedic Surgery, School of Medicine
    Objectives- To compare retrograde intramedullary nail (RIMN) and open reduction internal fixation (ORIF) in very distal periprosthetic distal femur fractures (PDFF) to determine if RIMN is an acceptable option for these fractures that are often considered too distal for IMN due to limited bone stock. Design- Retrospective comparative series Setting- Level One trauma center Patients- Patients treated with fracture fixation for a very distal PDFF, defined as the fracture extending to the anterior flange of the implant or distal. Fifty-six patients met inclusion criteria, with eight excluded for less than twelve months of follow-up. Intervention- Fracture fixation with RIMN or ORIF Main Outcome Measurements- The primary outcome was unplanned return to surgery. Secondary outcomes included fracture union, radiographic alignment, Visual Analog Score (VAS) and Patient-Reported Outcome Measurement Information System (PROMIS) Physical Function (PF) and Pain Interference (PI). Results- Mean follow up was 27 months. Twelve patients were treated with ORIF and 36 with RIMN. Twenty-one fractures were at the flange and 27 extended distal to the flange. There were no differences between fixation methods with respect to reoperation, deep infection, nonunion, malunion, VAS pain score, and PROMIS PI score. Mean PROMIS PF score was higher in the RIMN group compared to ORIF. There were five reoperations in the RIMN group (14%) and three in the ORIF group (25%). Conclusion- This is the largest series, to our knowledge, of a subset of very distal PDFFs. The results suggest that RIMN may be an acceptable treatment option for these very difficult fractures.
