Aims Tibial plateau fractures are serious injuries about the knee that have the potential to affect patients’ long-term function. To our knowledge, this is the first study to use patient-reported outcomes (PROs) with a musculoskeletal focus to assess the long-term outcome, as compared to a short-term outcome baseline, of tibial plateau fractures treated using modern techniques. Methods In total, 102 patients who sustained a displaced tibial plateau fracture and underwent operative repair by one of three orthopaedic traumatologists at a large, academic medical centre and had a minimum of five-year follow-up were identified. Breakdown of patients by Schatzker classification is as follows: two (1.9%) Schatzker I, 54 (50.9%) Schatzker II, two (1.9%) Schatzker III, 13 (12.3%) Schatzker IV, nine (8.5%) Schatzker V, and 26 (24.5%) Schatzker VI. Follow-up data obtained included: Visual Analogue Scale (VAS) or Numeric Rating Scale (NRS) pain scores, Short Musculoskeletal Functional Assessment (SMFA), and knee range of movement (ROM). Data at latest follow-up were then compared to 12-month data using a paired t-test. Results Patient-reported functional outcomes as assessed by overall SMFA were statistically significantly improved at five years (p < 0.001) compared with one-year data from the same patients. Patients additionally reported an improvement in the Standardized Mobility Index (p < 0.001), Standardized Emotional Index (p < 0.001), as well as improvement in Standardized Bothersome Index (p = 0.003) between the first year and latest follow-up. Patient-reported pain and knee ROM were similar at five years to their one-year follow-up. In total, 15 of the patients had undergone subsequent orthopaedic surgery for their knees at the time of most recent follow-up. Of note, only one patient had undergone knee arthroplasty following plateau fixation related to post-traumatic osteoarthritis (OA). Conclusion Knee pain following tibial plateau fracture stabilizes at one year. However, PROs continue to improve beyond one year following tibial plateau fracture, at least in a statistical sense, if not also clinically. Patients displayed statistical improvement across nearly all SMFA index scores at their minimum five-year follow-up compared with their one-year follow-up.

Objectives: To propose a previous implant fractures (PIFs) classification system with good interobserver reliability. Design: Retrospective classification. Setting: Four academic medical centers. Patients/Participants: A retrospective review of PIFs treated at 4 academic medical centers over 10 years was performed. Data collected included initial implant and PIF radiographs. There were 103 PIFs in 96 patients during the study period. Seventy-three (70.9%) were about plate/screw (PS) constructs and 30 (29.1%) were about intramedullary (IM) devices. Intervention: Assignment of PIF classification. Main Outcome Measurements: PIFs were classified based on initial implant (PS or IM) and fracture location with respect to the initial implant (proximal or distal to the implant, at the tip of the construct, or within the construct). Reliability of this scheme was assessed among 5 observers using Fleiss' kappa tests. Results: Of PIFs about plate/screw constructs, 26.0% were proximal/distal to the implant (classification: PS1), 57.5% involved bone between the most proximal/distal screw and the same end of the plate (classification: PS2), and 16.4% involved only bone between the most proximal and distal screws (classification: PS3). Of PIFs about IM, 43.3% were distal to the device (classification: IM1), 46.7% involved bone between the most proximal/distal locking bolt and the same end of the device (classification: IM2), and 10.0% involved only bone between locking bolts (classification: IM3). Interobserver reliability for the classification system was excellent between observers, κ = 0.839, P < 0.0005. Conclusions: The proposed system offers a simple method to classify and describe fractures that occur about a previously implanted fracture device. Development of a classification system will allow for comparison of treatment modalities between injury types.

Introduction: Autogenous iliac crest bone graft (ICBG) is considered the benchmark graft for nonunion repair. However, ICBG harvest is invasive and may provide reduced benefit to elderly patients. The purpose of this study was to compare the clinical and functional outcomes of ICBG use in fixation of fracture nonunions between elderly and nonelderly patients. Methods: Over a 13-year period, 242 patients who underwent operative repair of a long bone fracture nonunion and received autogenous ICBG were enrolled in a prospective research registry and followed. Data collected included patient demographics, injury information, and nonunion management. All patients had a minimum of 12 months of postoperative follow-up. Patients at least 65 years of age were classified as elderly, whereas younger patients were classified as nonelderly. Functional outcomes were evaluated at routine intervals postoperatively using the short musculoskeletal function assessment (SMFA) and visual analog scale pain scores. Bony union was determined radiographically. All postoperative complications were recorded. Results: Of the 242 patients included, 44 were elderly and 198 were nonelderly. No differences were found between groups with respect to postoperative pain scores or SMFA scores. Furthermore, time to union, rate of union, and postoperative complication rate did not differ between groups. Multivariate linear regression demonstrated that older age was not associated with time to union, postoperative pain scores, or postoperative SMFA scores after controlling for possible confounding variables. Discussion: The use of ICBG in nonunion repair among elderly patients is as effective as use in younger patients with a long bone nonunion. Concerns of increased postoperative complications and decreased rate of union in elderly patients receiving ICBG for treatment of fracture nonunion should be alleviated. ICBG remains the benchmark graft for nonunion repair among all age groups.T raumatic fracture nonunion presents a perennial challenge for both patients and orthopedic surgeons. Patients experience symptoms such as prolonged pain, fracture site mobility, and reduced functional

Purpose: The ability to predict contracture development after elbow fracture would benefit patients and physicians. This study aimed to identify factors associated with the development of posttraumatic elbow joint contracture. Methods: A retrospective review of elbow fractures (AO/Orthopaedic Trauma Association [OTA] type 13 and 21) treated at one institution between 2011 and 2015 was performed. Data collected included demographics, injury information, treatment, and postoperative elbow range of motion (ROM). Multivariate logistic regression analyses were performed to identify factors associated with contracture development. Notable contracture was defined as an arc of motion less than 100° flexion/extension, which has been associated with reduced ability to perform activities of daily living. Results: A total of 278 patients at least 1 8 years of age underwent surgical repair of an elbow fracture or fracture-dislocation during the study period and had at least 6 months of postoperative follow-up. Forty-two (15.1%) developed a clinically notable elbow contracture, of whom 29 (69.0%) developed heterotopic ossification (HO). Multivariate analysis of preoperative variables demonstrated that AO/OTA 13-C fracture classification (odds ratio [OR], 13.7, P = 0.025), multiple noncontiguous fractures (OR, 3.7, P = 0.010), and ulnohumeral dislocation at the time of injury (OR, 4.9, P = 0.005) were independently associated with contracture development. At 6 weeks postoperatively, an arc of elbow ROM less than 50° flexion/extension (OR, 23.0, P < 0.0005) and the presence of HO on radiographs (OR, 6.7, P < 0.0005) were found to be independent risk factors for significant elbow stiffness. Discussion: Ulnohumeral dislocation, multiple noncontiguous fractures, AO/OTA 13-C fracture classification, limited elbow ROM at 6 weeks postoperatively, and the presence of radiographic HO at 6 weeks postoperatively are associated with contracture development after surgical elbow fracture repair. Patients with these risk factors should receive aggressive physical therapy and be counseled as to the possible development of a contracture requiring surgical intervention.
