Risk factors for malalignment after intramedullary nail treatment of distal tibia fractures with associated fibula fractures. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:3265-3273.

Abstract
PURPOSE Malalignment of distal tibia fractures can lead to malunion/nonunion or alter the limb mechanical axis which may cause arthritis. Proposed methods to decrease malalignment include fibular fixation or multiplanar interlocking screws, however these remain controversial. This study aimed to identify factors associated with malalignment in distal tibial fractures with associated fibular shaft fractures. METHODS A retrospective review was performed of distal tibia fractures with associated fibular shaft fractures treated with intramedullary nailing at two level one trauma centers between 2015 and 2019. Cases involving malalignment (> 5° of deviation from anatomic axis on either coronal/sagittal axis) on final follow-up (minimum three months postoperatively) were compared to those without malalignment with regard to demographics, fracture characteristics, intraoperative characteristics, and complications. RESULTS The rate of malalignment was 13%. On multivariate analysis, multiplanar distal interlocking screw fixation (odds ratio [OR], 0.18; 95% confidence interval [CI] 0.03-0.92) was associated with a decreased rate of final malalignment, while nail diameter > 10 mm was associated with a higher rate (OR, 4.05; 95% CI 1.25-13.11). Fibular fixation was not associated with malalignment. CONCLUSION Multiplanar distal interlocking screws may protect against malalignment. Fibula fixation does not appear associated with a decreased rate of malalignment in distal tibia fractures treated with intramedullary nails. LEVEL OF EVIDENCE III.

Abstract
INTRODUCTION The objective of this study is to assess bone union, infection control, and reoperation rates in a series of patients with infected femoral or tibial nonunion treated with antibiotic-cement-coated rigid nails and to compare the results obtained with custom-made nails versus commercial nails. METHODS We retrospectively analyzed a series of consecutive patients with infected nonunion of the femur or the tibia treated with antibiotic-cement-coated rigid nails between January 2010 and 2020. We assessed patients' distinctive characteristics, initial injury, type of nail used (custom-made nail with vancomycin or commercial nail with gentamicin), success rate (bone union + infection control), reoperation rate, and failure rate. Comparative analyses were conducted between reoperated and non-reoperated patients regarding the type of nail used. A multivariate regression analysis was performed to assess the risk variables that impacted reoperation rates. RESULTS We included 54 patients with 22 (40.74%) infected femoral nonunions and 32 (59.25%) tibial nonunions, who were treated with 38 (70.37%) custom-made antibiotic-cement coated nails and 16 (29.62%) commercial nails. Bone union and infection control were achieved in 51 (94.44%) cases. The reoperation rate was 40.74% (n = 22), and the failure rate was 5.55% (n = 3). The use of custom-made nails was associated with a higher risk of reoperation (Odds Ratio 4.71; 95% Confidence Interval 1.10 - 20.17; p = 0.036). CONCLUSION Antibiotic-cement-coated nails reached a 94.44% success rate. Nails manufactured in the OR coated with vancomycin cement were associated with a higher risk of reoperation than commercial nails loaded with gentamicin cement. LEVEL OF EVIDENCE III comparative, observational, non-randomized.

Abstract
Objective: A retrospective examination was made of tibia shaft fractures treated with tibia intramedullary nail (IMN) (Dunitech Nite Tibial IMN Oliga Med Ankara-Turkey), which are designed with distal retractable claws, unlike classic imtramedullar nails. It was aimed to evaluate the effect on healing of the nail diameter and the distance between the fracture line and the proximal and distal fixation points of the IMN.
Material and Method: The study included 28 patients (18 males, 10 females; mean age 43.75 (18-69) years) treated with distal retractable claw tibia IMN for a diagnosis of unilateral tibia diaphyseal fracture between January 2020 and January 2022. The midpoint of the fracture line (F), the proximal fixation point of the locking screw (S), the distal fixation point of the retractable claw (T), and the isthmus mid-point (I) were determined as reference points. The FT, ST, and IT distances, the nail diameter (ND) and isthmus diameter (ID) were measured and the FT/ST ratio was calculated. Statistical evaluations were made of the relationships between the diameter and length measurements and the visual analog scale (VAS) and radiographic union score for tibia (RUST) scores at the end of one year.
Results: No statistically significant correlation was determined between the RUST and VAS scores and the diameter measurements or the distance between the proximal and distal fixation points of the IMN.
Conclusion: There was no effect on the fracture healing scores of the nail diameter or the distance between the proximal and distal fixation points in tibia shaft fractures treated with a tibia nail with distal retractable claws. The nail design with retractable claws provides strong fixation and stable fracture healing. The operating time is shorter resulting in less radiation exposure.

Abstract
INTRODUCTION The objective of this retrospective study was to assess the effect of the nail to canal ratio and the number and configuration of distal locking screws in bone healing in tibial shaft fractures. METHODS We analyzed 223 consecutive tibial shaft fractures treated with reamed intramedullary nailing between January 2014 and December 2020. We recorded and evaluated the nail to canal ratio (NCR) and the number and configuration of distal locking screws. Median NCR was 0.87 (IQR 0.82-0.94). Ten (4.48%) fractures were treated with one distal locking screw, 173 (77.57%) with two, and 40 (17.93%) with three. Uniplanar fixation was used in 63 (28.25%), biplanar in 150 (67.26%), and triplanar in 10 (4.48%) cases. Uni-, bi-, and multivariate analyses were performed to compare patients who achieved bone union with those who did not. RESULTS Bone union was achieved in 195 (87.44%) patients. Uni- and bivariate analyses showed that bone union increased significantly with larger NCR (p = 0.0001) and a greater number of locking planes (p = 0.001) and distal screws (p = 0.046). NCR > 0.78 (OR 48.77 CI 95% 15.39-154.56; p = < 0.0001) and distal locking screw configuration (OR 2.91 CI 95% 1.12-9.91; p = 0.046) were identified as independent variables for union. CONCLUSION Our findings suggest that in tibial shaft fractures treated with intramedullary nailing, NCR should be equal to or greater than 0.79. Additionally, distal locking screws should be used with a biplanar or triplanar configuration.

Abstract
PURPOSE To determine the effect of native tibia valga on intramedullary nail (IMN) fixation of tibial shaft fractures. METHODS Retrospective comparative cohort analysis of 110 consecutive patients with tibial shaft fractures undergoing IMN fixation at an urban level one trauma centre was performed. Medical records and radiographs were reviewed for demographics, tibia centre of rotation of angulation (CORA), nail starting point, incidence of varus malreduction, and nail/canal proportional fit. RESULTS Tibia valga (CORA of ≥ 3 degrees) was present in 37 (33.6%) patients. The anatomic nail starting point distance (in relation to the lateral tibial spine) was significantly greater in the tibia valga group (12.0 mm vs. 5.0 mm, mean difference: 7.1 mm, 95% CI: 5.8 to 8.3 mm, p < 0.0001). Varus malreduction was more common in the tibia valga group (10.8% vs. 1.4%, proportional difference: 9.4%, 95% CI: - 1.0 to 21.3%, p = 0.04). Varus malreduction in the tibia valga group was associated with a decreased nail width/inner canal width proportion on multivariate analysis (OR = 0.683, 95% CI: 0.468 to 0.995, p = 0.0004). CONCLUSION Native tibia valga is common, and the use of a standard coronal IMN starting point with poor nail fit can lead to iatrogenic varus malreduction. In patients with tibia valga, maximizing nail fit or utilization of a medial starting point should be considered.

Abstract
PURPOSE Early weight bearing (EWB) is often recommended after intramedullary nailing of tibial shaft fractures, however, the risks and benefits have not been critically evaluated in a systematic review or meta-analysis. Therefore, the aims of this study were to perform a systematic review and meta-analysis comparing EWB and delayed weight-bearing (DWB) after intramedullary nailing of tibial shaft fractures and assess the relationship between weight-bearing, fracture union and healing. METHOD This review included studies comparing the effects of EWB, defined as weight-bearing before 6 weeks, and DWB on fracture union and healing. PubMed, Embase, CINAHL, and the Cochrane Library were searched from inception to 9 May 2021. Risk of bias was assessed using the Down's and Black Checklist and Cochrane Risk of Bias Tool 2.0. Data were synthesised in a meta-analysis, as well as narrative and tabular synthesis. RESULTS Eight studies were included for data extraction and meta-analysis. The analysis produced mixed results and found a significant decrease in mean union time (-2.41 weeks, 95% confidence interval: -4.77, -0.05) with EWB and a significant Odd's Ratio (OR) for complications with DWB (OR: 2.93, 95% CI: 1.40, 6.16). There was no significant difference in rates of delayed union, non-union, re-operation and malunion. CONCLUSION The included studies were of moderate risk of bias and demonstrated shorter union time and fewer complications with EWB. However, current evidence is minimal and has significant limitations. The role of EWB in high-risk patients is yet to be examined. Further well-designed, randomised studies are required on the topic.

Abstract
OBJECTIVES In patients with wide femoral canals, an undersized short nail may not provide adequate stability, leading to toggling of the nail around the distal interlocking screw and subsequent loss of reduction. The purpose of this study was to identify risk factors associated with nail toggle and to examine whether increased nail toggle is associated with increased varus collapse. DESIGN Retrospective cohort study. SETTING Level 1 and level 3 trauma center. PATIENTS/PARTICIPANTS Seventy-one patients with intertrochanteric femur fractures treated with short cephalomedullary nails (CMN) from October 2013 to December 2017. INTERVENTION Short CMN. MAIN OUTCOME MEASUREMENTS Nail toggle and varus collapse were measured on intraoperative and final follow-up radiographs. Risk factors for nail toggle including demographics, fracture classification, quality of reduction, Dorr type, nail/canal diameter ratio, lag screw engaging the lateral cortex, and tip-apex distance (TAD) were recorded. RESULTS On multivariate regression analysis, shorter TAD (P = .005) and smaller nail/canal ratio (P < .001) were associated with increased nail toggle. Seven patients (10%) sustained nail toggle >4 degrees. They had a smaller nail/canal ratio (0.54 vs 0.74, P < .001), more commonly Dorr C (57% vs 14%, P = .025), lower incidence of lag screw engaging the lateral cortex (29% vs 73%, P = .026), shorter TAD (13.4 mm vs 18.5 mm, P = .042), and greater varus collapse (6.2 degrees vs 1.3 degrees, P < .001) compared to patients with nail toggle < 4 degrees. CONCLUSIONS Lower percentage nail fill of the canal and shorter TAD are risk factors for increased nail toggle in short CMNs. Increased nail toggle is associated with increased varus collapse.Level of evidence: Therapeutic Level III.

Abstract
PURPOSE We aimed to 1) identify predictors of delayed and nonunion of tibial shaft fractures in patients treated with intramedullary nailing (IMN), including patient demographics and surgical factors, and 2) determine whether the nail/shaft ratio is associated with delayed and nonunion. METHODS This retrospective, multicenter study included 315 patients with tibial shaft fracture treated with IMN between 2014 and 2019 and excluded patients with insufficient follow-up for 12 months, lost data and inadequate radiographs. Finally, we analyzed 258 patients (184 males; 74 females). Main outcome measurements were delayed union at 6 and nonunion at 12 months after surgery as determined on anteroposterior and lateral radiographs. We extracted the following as risk factors of delayed and nonunion: age, sex, BMI, fracture site, fracture type, injury energy, smoking history, and nail/shaft ratio. We conducted logistic regression analysis to investigate risk factors of delayed and nonunion using these extracted items as explanatory variables. RESULTS Type C fracture was independently associated with delayed union (odds ratio 2.9, 95% confidential interval: 1.04-8.09, P = 0.04). Nail/shaft ratio was not an independent factor of delayed union. No independent explanatory factors were related to nonunion. CONCLUSIONS Type C fractures, which were unstable and fragmented, was associated with delayed union in tibia fractures treated with IMN, whereas nail thickness was not associated with delayed or nonunion fractures.

Abstract
Introduction Extra-articular diaphyseal tibial fractures are a common injury and are often treated with intramedullary nailing (IMN). Weight-bearing (WB) of simple tibial fractures treated with an IMN immediately as pain allows is now standard practice. Our aim was to assess the impact of varied WB on fracture union following IMN of diaphyseal tibia fractures. Methods We conducted a retrospective cohort study of tibial fractures treated with IMN in our department between 2012-2017. WB status was recorded in the post-operative note and subsequently reviewed in the patients’ follow-up appointments. Patients were divided in three groups; Group I: immediate full-WB, Group II: non-WB for 6 weeks and Group III: 2 weeks non-WB, 4 weeks increasing partial-WB and full-WB at 6 weeks. Radiographic union score for tibial fractures (RUST) of ≥10 at a painless fracture site was considered as evidence of fracture union. Results 92 patients with comparable pre-operative demographics [mean age 40 y (16-88)] were included. The median union time in weeks for each group was: Group I 17.3, Group II 21.7 and Group III 19.5 (F 1.09, p 0.34). Survival analysis and log rank test did not show any difference in union times between the three groups (x2 1.1, p 0.57). 12 delayed unions were identified across all groups. Multiple logistic regression identified three factors that could increase the rate of delayed union – non-WB, smoking and IMN size 11/12 mm - however the results were not statistically significant. Conclusion Immediate post-operative WB does not adversely affect union time in statically locked IMNs. In fact, although our data show no statistically significant difference in fracture healing between the three groups, full WB seems to decrease overall time to union. In conclusion, we could suggest that full WB after IMN in patients with AO 42-A/B type fractures is safe practice.

Abstract
External fixation is often used for temporary stabilization of the tibia in several clinical scenarios. Conventional placement of external fixation pins may impede instrumentation with intramedullary nailing, thus requiring pin removal, loss of reduction, and increased operative time during definite fixation. In this article, we describe a strategic pin placement routinely used at our institution in which we create a medially based inverted triangular construct that allows for pins to remain in place during definitive fixation.

Abstract
OBJECTIVES To explore the effect of intramedullary pin size on the biology of a healing fracture, specifically endochondral angiogenesis. We hypothesized that fracture fixation with a smaller pin would permit greater interfragmentary strain resulting in increased total amount of vascular endothelial growth factor within the callus and greater angiogenesis compared to fixation with a larger pin. METHODS Transverse mid-shaft femur fractures in 8-week-old mice were fixed with either a 23-gauge (G) or 30-G pin. Differences in interfragmentary strain at the fracture site were estimated between cohorts. A combination of histology, gene expression, serial radiography, and microcomputed tomography with and without vascular contrast agent were used to assess fracture healing and vascularity for each cohort. RESULTS Larger soft-tissue callus formation increased vascular endothelial growth factor-A expression, and a corresponding increase in vascular volume was observed in the higher strain, 30-G cohort. Radiographic analysis demonstrated earlier hard callus formation with greater initial interfragmentary strain, similar rates of union between pin size cohorts, yet delayed callus remodeling in mice with the larger pin size. CONCLUSIONS These findings suggest that the stability conferred by an intramedullary nail influences endochondral angiogenesis at the fracture.

Ongoing studies investigating fracture healing have uncovered and allowed investigators to gain a better understanding of where the variety of cells, which participate in this process, originate, and how they communicate as well as how they can be enhanced to successfully heal a fracture when the process has slowed or failed completely. This brief review will highlight some of the recent findings regarding the role the immune system in fracture healing and how these cells communicate with each other during the healing process. In addition, two 2 methods that have recently been shown to be promising techniques in supporting fracture when it stalls or reversing the process, when the fracture has failed to heal, will also be described.

Predictors of mechanical complications after intramedullary nailing of tibial fractures. Orthop Traumatol Surg Res 2019; 105:523-527. [PMID: 30954391 DOI: 10.1016/j.otsr.2019.01.015] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2018] [Revised: 10/27/2018] [Accepted: 01/14/2019] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Intramedullary (IM) nailing is the gold standard treatment for tibial shaft fractures, but can be associated with various mechanical complications, including delayed union. HYPOTHESIS We believe that complications do not occur randomly, but in certain conditions that contribute to their development. Risk factors likely to predict delayed union can be identified to support prevention. MATERIALS AND METHODS A cohort of 171 fractures treated by IM nailing between 2005 and 2015 was reviewed retrospectively. Independent variables included intrinsic, patient-related factors and extrinsic factors such as those related to the fracture or surgery. A multiple logistic regression model was used to determine which factors can predict each type of complication. RESULTS Delayed union occurred in 22.8% of patients. Smoking and high-energy trauma were risk factors. Hardware breakage was significantly reduced (p<0.05) when the nail diameter was greater than 10mm. A nail diameter/reamer diameter ratio outside the recommended limits (0.80-0.99) was more likely to be associated with screw failure. Diabetes is a risk factor for hardware migration, which itself is associated with other complications. DISCUSSION Nonunion is the most common complication after IM nailing of tibial shaft fractures. Smoking cessation after a fracture is necessary in our opinion, even if the literature is ambivalent on this aspect and stopping to smoke once the fracture occurs may not be sufficient to prevent a poor outcome. Use of a nail diameter/reamer diameter between 0.80 and 0.99 favors union and prevents hardware breakage. Hardware migration in a diabetic patient may be a warning sign of other types of complications. LEVEL OF EVIDENCE Retrospective cohort study. Level IV.

Abstract
AIM The aim of this study was to determine how outcome is measured following adult tibial fracture in the modern era of functional outcome measurement and patient reported outcomes. METHODS A systematic review of publications since 2009 was performed, looking specifically at acute, adult tibial shaft fractures. Ovid Medline, Embase, PubMed and PsycINFO databases were searched for relevant titles which were then screened by two authors with adjudication where necessary by a third. Relevant articles were reviewed in full and data was extracted concerning the study participants, study design and any measures that were used to quantify the results following fracture. The results were collated and patient reported outcome measures were assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) standards. RESULTS A total of 943 titles and articles were reviewed, with 117 included for full analysis. A wide range of clinical and radiological "outcomes" were described, along with named clinician- and patient-reported outcome measures. There was considerable heterogeneity and lack of detail in the description of the simplest outcomes, such as union, infection or reoperation. Reported clinician and patient reported outcome measures are variably used. None of the identified patient reported outcome measures have been validated for use following tibial fracture. CONCLUSION We recommend definition of a core outcome set for use following tibial fracture. This will standardise outcome reporting following these injuries. Furthermore, there is need for a validated patient reported outcome measure to better assess patient important outcomes in this patient group.

Abstract
OBJECTIVES To report the clinical results after treatment of pediatric femoral shaft fractures with the SIGN Fracture Care International (SIGN) pediatric and standard fin nails. DESIGN Retrospective review of prospectively collected data. SETTING Sixteen global SIGN centers from 2003 to 2013. PATIENTS/PARTICIPANTS One hundred twelve pediatric patients who sustained a diaphyseal pediatric femoral shaft fracture. INTERVENTION Intramedullary fixation with the standard or pediatric SIGN nail. MAIN OUTCOME MEASUREMENTS Main outcome measurements include clinical and radiographic healing and postoperative complications. RESULTS The mean age of the pediatric fin patients was 9.4 years (4-15) and 11.2 years (4-18) for the standard fin patients. Painless weight bearing was achieved in 94.7% and 94.5% of the patients at the last follow-up. In total, 23 patients had repeat surgery for the removal of implant. Failure of implant with bending of the nail and/or a valgus or varus deformity (>10 degrees) was noted in 7/57 (12.3%) of the patients treated with the pediatric fin nail, of which 6/7 were >10 years old. Five of these 7 patients were classified as technical errors attributed to inadequate nail diameter, length, or initial malreduction. No complications were noted at any age in the standard fin nail group. CONCLUSIONS In resource-poor settings, SIGN pediatric fin and standard fin nails seem to be an effective treatment option for femoral shaft fractures. In patients with larger canals, the surgeon should consider using the standard fin nail for improved stability and to minimize potential complications. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
PURPOSE Since its development in 1999, the SIGN nail has been used in over 190,000 surgeries spanning 55 countries. To date, however, evaluation of SIGN nail outcomes has been limited to small prospective studies or large retrospective studies using SIGN's online database. This study uses the experience of a single, independent Cambodian surgical clinic to characterize common complications, provide commentary on ways to reduce the risk of those complications, and determine whether several observed nail fractures were due to metallurgic defects. METHODS Clinic medical records were queried to identify complications in patients with SIGN nails. Data was abstracted including age, sex, mechanism of injury, and latency between injury, primary implantation, and presentation with a complication. Two nails that fractured in vivo were analyzed by light microscopy, scanning electron microscopy, and polarized light microscopy after chemical etching. RESULTS Fifty-four complications in 51 patients were identified. The most common complications were non-union (n = 26, 48%), infection (n = 16, 30%), flexion limitation (n = 11, 20%), nail fracture (n = 4, 7%), delayed union (n = 4, 7%), and malunion (n = 4, 7%). Other complications included broken or floating screws. Fractography revealed that two of the fractured nails most likely failed by fatigue followed by fast fracture at the site of non-union. We found no evidence of intrinsic nail defects. We identified multiple inconsistencies between SIGN's database and independent clinic records. CONCLUSIONS Non-union and infection were common relative to all complications. Based on radiographic review, risk for non-union and malunion can be minimized by selecting an appropriate nail diameter, using multiple interlocking screws, and employing the correct implant and approach for fracture morphology when using SIGN nails. Nail fractures were unlikely to be caused by metallurgical flaws. Further study is necessary to determine the appropriate management of non-unions based on radiographic and clinical factors.

Abstract
BACKGROUND Open tibia fractures usually occur in high-energy mechanisms and are commonly associated with multiple traumas. The purposes of this study were to define the epidemiology of open tibia fractures in severely injured patients and to evaluate risk factors for major complications. METHODS A cohort from a nationwide population-based prospective database was analyzed (TraumaRegister DGU®). Inclusion criteria were: (1) open or closed tibia fracture, (2) Injury Severity Score (ISS) ≥ 16 points, (3) age ≥ 16 years, and (4) survival until primary admission. According to the soft tissue status, patients were divided either in the closed (CTF) or into the open fracture (OTF) group. The OTF group was subdivided according to the Gustilo/Anderson classification. Demographic data, injury mechanisms, injury severity, surgical fracture management, hospital and ICU length of stay and systemic complications (e.g., multiple organ failure (MOF), sepsis, mortality) were collected and analyzed by SPSS (Version 23, IBM Inc., NY, USA). RESULTS Out of 148.498 registered patients between 1/2002 and 12/2013; a total of 4.940 met the inclusion criteria (mean age 46.2 ± 19.4 years, ISS 30.4 ± 12.6 points). The CTF group included 2000 patients (40.5%), whereas 2940 patients (59.5%) sustained open tibia fractures (I°: 49.3%, II°: 27.5%, III°: 23.2%). High-energy trauma was the leading mechanism in case of open fractures. Despite comparable ISS and NISS values in patients with closed and open tibia fractures, open fractures were significantly associated with higher volume resuscitation (p < 0.001), more blood (p < 0.001), and mass transfusions (p = 0.006). While the rate of external fixation increased with the severity of soft tissue injury (37.6 to 76.5%), no major effect on mortality and other major complications was observed. CONCLUSION Open tibia fractures are common in multiple trauma patients and are therefore associated with increased resuscitation requirements, more surgical procedures and increased in-hospital length of stay. However, increased systemic complications are not observed if a soft tissue adapted surgical protocol is applied.

Trajectory of Short- and Long-Term Recovery of Tibial Shaft Fractures After Intramedullary Nail Fixation. J Orthop Trauma 2017; 31:559-563. [PMID: 28538288 DOI: 10.1097/bot.0000000000000886] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To determine the trajectory of recovery after tibial shaft fracture treated with intramedullary nail over the first 5 years and to evaluate the magnitude of the changes in functional outcome at various time intervals. DESIGN Prospective cohort study. SETTING A Level 1 trauma center. PATIENTS/PARTICIPANTS One hundred thirty-two patients with tibial shaft fracture (OTA 42-A, B, C) were enrolled into the Center's prospective orthopaedic trauma database between January 2005 and February 2010. Functional outcome data were collected at baseline, 6 months, 1 year, and 5 years. INTERVENTION Enrolled patients were treated acutely with intramedullary nailing of their tibia. MAIN OUTCOME MEASUREMENTS Evaluation was performed using the Short Form-36 and Short Musculoskeletal Function Assessment (SMFA). RESULTS Mean SF-36 physical component scores improved between 6 and 12 months (P = 0.0008) and between 1 and 5 years (P = 0.0029). Similarly, mean SMFA dysfunction index scores improved between 6 and 12 months (P = 0.0254) and between 1 and 5 years (P = 0.0106). In both scores, the rate or slope of this improvement is flatter between 1 and 5 years than it is between 6 and 12 months. Furthermore, SF-36 and SMFA scores did not reach baseline at 5 years (SF-36 P < 0.0001, SMFA P = 0.0026). A significant proportion of patients were still achieving a minimal clinically important difference in function between 1 and 5 years (SF-36 = 54%, SMFA = 44%). CONCLUSIONS The trajectory of functional recovery after tibial shaft fracture is characterized by an initial decline in function, followed by improvement between 6 and 12 months. There is still further improvement beyond 1 year, but this is of flatter trajectory. The 5-year results indicate that function does not improve to baseline by 5 years after injury. LEVEL OF EVIDENCE Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Current Evidence: Plate Versus Intramedullary Nail for Fixation of Distal Tibia Fractures in 2016. J Orthop Trauma 2016; 30 Suppl 4:S2-S6.

Abstract
Displaced distal tibia shaft fractures are effectively treated with standard plates and intramedullary nails. Plate fixation performed with meticulous soft tissue handling results in minimal risks of infection and poor wound healing. Standard plates have high rates of primary union, whereas locking plates may delay union because of increased stiffness. Tibial healing may also be delayed after plating of the fibula, although fibula reduction and fixation may aid accuracy of reduction of the tibia. Malalignment occurs more often with infrapatellar intramedullary nailing versus plates, and early results of suprapatellar nailing appear promising in minimizing intraoperative malalignment. Long-term function after fixation of the distal tibia is good for most, with poor outcomes often associated with baseline social and mental health issues.
