He M, Zhang X, Cheng T, Hu J, Li J. Imaging risk factors for predicting postoperative complications of intramedullary nailing for tibial fracture. Eur J Trauma Emerg Surg 2024; 50:1489-1496. [PMID: 38421390 PMCID: PMC11458704 DOI: 10.1007/s00068-024-02480-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Accepted: 02/19/2024] [Indexed: 03/02/2024]
Abstract
OBJECTIVE The objective of this study was to analyze the ratio of fracture site diameter to tibial isthmus diameter (TFI ratio) as a predictor of postoperative complications, including malunion and delayed union, after tibial intramedullary nailing for middle and lower tibial fractures. METHODS Data were collected from all adult patients older than 20 years of age who underwent tibial intramedullary nailing for middle and lower tibial fractures between January 2015 and January 2023 and were followed up for at least 1 year. Diabetes history, smoking history, fracture type, injury mechanism, surgical method, surgical approach, diameter of the medullary cavity at the fracture site, and diameter of the tibial isthmus were recorded. Logistic regression analysis was used to determine the variables affecting the occurrence of complications. The TFI ratio was used to calculate the sensitivity and specificity of the parameters, and ROC curves were generated to establish TFI ratio thresholds for predicting complications. RESULTS A total of 123 patients with middle and lower tibial fractures were treated with intramedullary nails. The mean age of the patients was 43.72 years (range, 21-81 years); 89 were males, and 34 were females. Univariate logistic regression analysis showed that fracture type, open reduction surgery, superior patellar approach, and TFI ratio were significantly correlated with postoperative complications after intramedullary nailing of a tibial fracture. Multivariate logistic regression analysis showed that the TFI ratio was an independent risk factor for complications (P = 0.001*). By using the TFI ratio as a predictor of complications, an ROC curve was generated to establish a threshold. The ROC curve showed that a TFI ratio ≥ 1.31 had a sensitivity of 0.89, a specificity of 0.71, and an area under the ROC curve of 0.82 for predicting complications. CONCLUSIONS The results of this study suggest that a wider intramedullary diameter and a shorter fixed length at the fracture site are associated with a higher incidence of complications after tibial intramedullary nailing. The TFI ratio may be used as a reliable parameter for predicting complications after such surgery. In patients with a high TFI ratio (≥ 1.31), additional reduction and fixation techniques may be needed to obtain and maintain fracture reduction.

[PMID: 38070327 DOI: 10.1016/j.injury.2023.111185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 10/15/2023] [Accepted: 11/04/2023] [Indexed: 01/29/2024]
Abstract
INTRODUCTION Hip fractures have become a major public health priority due to their increasing incidence. Intramedullary (IM) nailing has gained popularity as a surgical technique for managing these fractures. However, comparative studies with extramedullary devices indicate potentially increased mechanical complications associated with IM nailing. Specifically, there have been recent reports of early implant fracture associated with the TFNA system. This study compares the rate of mechanical complications between 3 implants. Secondarily, we analysed the factors associated with implant fracture and all other mechanical complications. METHODS This retrospective study included 803 IM nails performed between 2008-2021 for the fixation of proximal femur fractures at a level 1 trauma centre. We recorded patient demographics, AO fracture classification, implant specification and intra-operative parameters such as tip-apex distance, Cleveland index, reduction quality, presence of medial calcar integrity, neck-shaft angle. The outcomes analysed included implant fracture, lag screw cut-out, >10 mm backing out, autodynamisation, periprosthetic fracture, non-union at 6 months and time to revision surgery. RESULTS The overall implant fracture rate was 3.1 % (25/803), with no statistically significant difference between the three devices (p = 0.51). The TFNA group included 183 patients with a median follow-up of 1.6 years. The TFNA fracture rate was 2.2 % (4/183) which occurred at 207 +/- 16.66 days post-operatively. The rate of all mechanical complications was 4.9 % in the TFNA group, 12.9 % in the InterTAN group and 17 % in the IMHS group. Non-union (p < 0.001) and increasing lag screw length (p < 0.02) were identified as risk factors for implant fracture and other mechanical complications. The reverse oblique fracture pattern (AO 31 A3.1) was associated with mechanical complications only (p < 0.01). The cumulative survival rates without revision for the TFNA, InterTAN, IMHS groups were 97.8 %, 95.5 % and 87.9 % respectively at 2.5 years. DISCUSSION The rates of implant fracture were comparable between the three nailing systems. The TFNA provides effective fixation for proximal femur fractures using a traditional screw without cement augmentation. The TFNA was associated with an overall reduction in mechanical complications compared to the InterTAN and IMHS. Previously reported mechanical complications associated with IM Nails may relate to older device designs.

Cureus 2023; 15:e49156.

Abstract
Background and objective Extra-articular fractures of the tibia are common orthopedic injuries that are frequently treated with rigid intramedullary nailing. Fracture location and pattern may increase the risk of nonunion or malunion in fractures managed with intramedullary nails. This study aimed to assess the relationship between fracture pattern and location with malunion and nonunion. The primary objective was to evaluate the influence of fracture location and pattern on adverse clinical outcomes such as nonunion, delayed union, and malunion in tibial shaft fractures that are treated operatively with rigid intramedullary nails. Methodology This was a retrospective cross-sectional study conducted on patients operated in a tertiary care center in the Kingdom of Bahrain. The study included patients who sustained tibia shaft fractures and were subsequently operated with intramedullary of the tibia. The primary endpoint was the rate of adverse outcomes associated with fracture patterns. Fracture characteristics were to determine which fracture patterns healed well with intramedullary nailing and which fractures ended up with malunion or nonunion and would likely benefit from additional measures to augment the nail fixation and help encourage union. Results One hundred and eighty-nine patients were included in the study. The level of associated fibula fracture was significantly associated with an increased risk of nonunion and malunion (P = 0.0034, P = 0.001). The presence of a concomitant distal fibula fracture in association with tibia fractures increased the odds of nonunion (odds ratio [OR] = 4.871, P = 0.033, confidence interval [CI] = 1.133-20.948). Conclusions The level and pattern of some tibia and fibula fractures were associated with nonunion, malunion, and delayed union. Further studies with more robust follow-up are needed to examine these findings in greater detail.

Abstract
Long bone fractures are a concern in long-duration exploration missions (LDEM) where crew autonomy will exceed the current Low Earth Orbit paradigm. Current crew selection assumptions require extensive complete training and competency testing prior to flight for off-nominal situations. Analogue astronauts (n = 6) can be quickly trained to address a single fracture pattern and then competently perform the repair procedure. An easy-to-use external fixation (EZExFix) was employed to repair artificial tibial shaft fractures during an inhabited mission at the Mars Desert Research Station (Utah, USA). Bone repair safety zones were respected (23/24), participants achieved 79.2% repair success, and median completion time was 50.04 min. Just-in-time training in-mission was sufficient to become autonomous without pre-mission medical/surgical/mechanical education, regardless of learning conditions (p > 0.05). Similar techniques could be used in LDEM to increase astronauts' autonomy in traumatic injury treatment and lower skill competency requirements used in crew selection.

Abstract
INTRODUCTION Prosthetic joint infection (PJI) is a destructive complication of knee replacement surgery (KR). In two-stage revision a spacer is required to maintain limb length and alignment and provide a stable limb on which to mobilise. Spacers may be articulating or static with the gold standard spacer yet to be defined. The aims of this scoping review were to summarise the types of static spacer used to treat PJI after KR, their indications for use and early complication rates. METHODS We conducted a scoping review based on the Joanna Briggs Institute's "JBI Manual for Evidence Synthesis" Scoping review reported following Preferred Reporting Items for Systematic Review and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. MEDLINE, EMBASE and CINAHL were searched from 2005 to 2022 for studies on the use of static spacers for PJI after KR. RESULTS 41 studies (1230 patients/knees) were identified describing 42 static spacer constructs. Twenty-three (23/42 [54.2%]) incorporated cement augmented with metalwork, while nineteen (19/42, [45.9%]) were made of cement alone. Spacers were most frequently anchored in the diaphysis (22/42, [53.3%]), particularly in the setting of extensive bone loss (mean AORI Type = F3/T3; 11/15 studies 78.3% diaphyseal anchoring). 7.1% (79 of 1117 knees) of static spacers had a complication requiring further surgery prior to planned second stage with the most common complication being infection (86.1%). CONCLUSIONS This study has summarised the large variety in static spacer constructs used for staged revision KR for PJI. Static spacers were associated with a high risk of complications and further work in this area is required to improve the quality of care in this vulnerable group.

Abstract
INTRODUCTION Distal tibia fractures often occur in younger, high demand patients, though the literature surrounding management remains contentious. This study sought to quantitatively determine differences in kneeling ability and self-reported knee function in patients managed with either intramedullary nailing (IMN) or open reduction internal fixation (ORIF) with compression plating following distal tibia fracture to assist in the preoperative consent process. HYPOTHESIS There is no difference in kneeling tolerance following either tibial nailing or plate fixation of distal tibia fractures. MATERIAL AND METHODS Retrospective sampling of public hospital data with outpatient prospective functional testing were completed. The primary outcome measure was the Kneeling Test (KT). Secondary outcome measures were The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Forgotten Joint Score (FJS) for the knee joint. There were 28 patients recruited (18 IMN and 10 ORIF) with a mean age of 44years. Mean overall follow-up was 13.3months (range 8-25, SD 3.6). All fractures had completely healed without postoperative complication. RESULTS The IMN affected limb had a significantly worse overall kneeling function than their non-affected limb (mean KT: 70.4 vs. 94.9 respectively, p<0.005) Additionally, the IMN group performed significantly worse when compared to the ORIF group (mean KT 70.4 vs. 92.5 respectively, p<0.005). No significant differences (p>0.05) in kneeling function existed for the ORIF group when comparing affected to non-affected limbs. Secondary outcome analysis showed significantly worse overall WOMAC and FJS in the IMN group compared to the ORIF group (mean WOMAC 19.3 vs. 6.9 respectively, p=0.040; mean FJS 38.3 vs. 75.9 respectively, p=0.005). DISCUSSION The use of intramedullary nailing for the treatment of distal tibia fracture results in a mean reduction of 20% in kneeling tolerance in comparison to ORIF. The resulting kneeling tolerance is comparable to that of patients post-total knee arthroplasty. The present findings should assist in the consent process for patients with high kneeling demands in sportive, professional or cultural pastimes. LEVEL OF EVIDENCE IV; retrospective cohort study with quantitative outcome measurement.

An Easy-To-Use External Fixator for All Hostile Environments, from Space to War Medicine: Is It Meant for Everyone's Hands? J Clin Med 2023; 12:4764.

Abstract
Long bone fractures in hostile environments pose unique challenges due to limited resources, restricted access to healthcare facilities, and absence of surgical expertise. While external fixation has shown promise, the availability of trained surgeons is limited, and the procedure may frighten unexperienced personnel. Therefore, an easy-to-use external fixator (EZExFix) that can be performed by nonsurgeon individuals could provide timely and life-saving treatment in hostile environments; however, its efficacy and accuracy remain to be demonstrated. This study tested the learning curve and surgical performance of nonsurgeon analog astronauts (n = 6) in managing tibial shaft fractures by the EZExFix during a simulated Mars inhabited mission, at the Mars Desert Research Station (Hanksville, UT, USA). The reduction was achievable in the different 3D axis, although rotational reductions were more challenging. Astronauts reached similar bone-to-bone contact compared to the surgical control, indicating potential for successful fracture healing. The learning curve was not significant within the limited timeframe of the study (N = 4 surgeries lasting <1 h), but the performance was similar to surgical control. The results of this study could have important implications for fracture treatment in challenging or hostile conditions on Earth, such as war or natural disaster zones, developing countries, or settings with limited resources.

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.

[PMID: 34579990 DOI: 10.1016/j.jos.2021.09.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 08/31/2021] [Accepted: 09/01/2021] [Indexed: 02/09/2023]
Abstract
BACKGROUND There is a need for a novel therapeutic strategy for an earlier prediction of long bone union failure as compared to previous methodologies. This study aimed to determine whether a combination of two diagnostic tools would result in a more accurate diagnosis of delayed union. METHODS The inclusion criteria were as follows: patients with tibial shaft fracture who underwent treatment with intramedullary nailing (IMN) as definitive internal fixation (IF). The study included a total of 114 patients with 116 tibial shaft fractures treated with IMN as definitive IF. Radiographic apparent bone gap (RABG) and nonunion risk determination score (NURDS) can be used to predict nonunion. However, this study aimed to determine whether combination of RABG and NURDS could help deduce a more accurate prediction of delayed union. RESULTS The union rate was found to be 85% (99 fractures), the delayed union rate was found to be 15% (17 fractures), and the rate of nonunion requiring additional surgical intervention was estimated to be 4% (5 out of the 17 delayed union cases). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of RABG were found to be 82.3%, 76.0%, 36.8%, and 96.2%, respectively, when an RABG cutoff value of 5.0 mm was applied to our patient cohort. The sensitivity, specificity, PPV, and NPV of NURDS were found to be 47.1%, 82.0%, 30.8%, and 90.1%, respectively, when a NURDS cutoff value of 8.0% was applied to our patient cohort. When RABG and NURDS were above their respective cutoff values, the sensitivity and PPV were estimated to be 90.0% and 56.3%, respectively. When RABG and NURDS were below their respective cutoff values, the specificity and NPV were estimated to be 90.1% and 98.5%, respectively. CONCLUSIONS The combination of RABG and NURDS evaluation immediately after surgery helps surgeons identify patients who are at a high risk of delayed union, facilitating careful monitoring of these patients and consideration of additional treatments.

The relevance of the number of distal locking planes and nail to canal ratio in bone healing after intramedullary nailing in tibial shaft fractures. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2022:10.1007/s00590-022-03401-0. [PMID: 36208335 DOI: 10.1007/s00590-022-03401-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Accepted: 09/28/2022] [Indexed: 05/19/2023]
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
Background Tibial shaft fractures account for 17% of all lower limb fractures. Nonunion and infection rates are estimated to be between 2% and 10%. Bone healing is a complex process that is influenced by biological, mechanical, and systemic factors. Adverse smoking effects on cardiovascular and respiratory systems have been well documented. An increasing interest in the effect of smoking on fracture healing following trauma has been noted in recent years. The biological consequence of smoking is relevant, especially in trauma surgery where no way of preventing presurgical smoking has been noted, hence increasing the patient’s risk of nonunion. Cigarette smoking has been shown to impair fracture union and wound healing and lead to an increased risk of fracture site infection. Smoking and high-energy trauma are considered important risk factors for the delayed union of tibial shaft fractures. Objectives This study aims to assess the adverse effects of smoking in patients with tibial shaft fractures following trauma and fracture fixation. Materials and methods A retrospective cohort study was done on 110 (55 smokers and 55 nonsmokers) patients treated with intramedullary nailing or plating for tibial shaft fractures between July 2017 and January 2021 in the hospital of the current study. Fracture healing was assessed at the end of months 1, 3, and 6 and year 1. Results The mean time of healing in smokers was >48 weeks, whereas the average time to union was 24 weeks in nonsmokers. The majority (54.6%) of smokers took >48 weeks to heal, whereas 81.8% of patients in the nonsmoking group took 24-28 weeks to heal. Conclusion Similar to the results obtained in previous studies, our study showed that smoking hinders fracture healing after surgical fixation, and smokers have a higher chance of developing surgical site infection and osteomyelitis. Smokers take a longer time for radiological union and also have a high chance of delayed union and nonunion when compared with nonsmokers, which was shown in our study and is consistent with the results obtained in previous studies. Postoperative smoking cessation is as important as preoperative smoking cessation, and patients should be strictly counseled regarding the same.

Abstract
The article presents a new medical device through an authorial and interdisciplinary approach. It consists of a flexible external fixator, whose flexible property may bring advantages over rigid mechanisms. Its design was inspired by the DNA biological mechanism of condensation, while the modeling was based on the pseudo-rigid modeling technique. From the models obtained, this study conducted prototyping and computational tests to obtain a proof-of-concept of the bioinspired theory and dynamic functioning effectiveness. The prototyping relied on hot glue manufacturing and the computational simulations consisted of linear static analysis. The experimental analysis concluded that the prototype with fewer beams and thinner beams delivered better results in all three parameters: flexibility, height variation and rotation arc. In the computational analysis, among the design models with the variation of the number of beams, the model with 8 beams performed better. Concerning thickness variation, the one whose beams measured 8mm in thickness showed better results. Among the models with length variation, the design made with 100 mm long beams better equilibrated the parameters.

Abstract
OBJECTIVES To identify factors associated with the need for reoperations in patients treated surgically for fracture nonunion. DESIGN Retrospective cohort study. SETTING One urban Level 1 trauma center and an orthopaedic specialty hospital. PATIENTS/PARTICIPANTS This study included 365 patients who did not and 95 patients who did undergo a reoperation after nonunion repair. INTERVENTION All patients who underwent fracture nonunion repair were identified. Baseline demographic, injury, and surgical information were collected. These factors were compared between patients who did and did not require an unplanned reoperation. MAIN OUTCOME MEASUREMENTS An unplanned reoperation after index fracture nonunion surgery. RESULTS When compared with patients who did not undergo a reoperation after their index fracture nonunion surgery, patients who underwent at least 1 reoperation had a greater proportion of those who sustained an open fracture, a high-energy injury, initial neurologic or vascular injuries, the need for a flap or soft tissue graft at initial treatment, and lower extremity injuries with univariate analysis. Unplanned reoperation was also associated with diagnosis of "infected" nonunion at initial nonunion surgery. Multivariate analysis confirmed initial nerve or vascular injuries and positive infection status were statistically significant predictors of a reoperation. CONCLUSIONS Initial injury characteristics such as nerve or vascular injury at initial injury and positive infection status at the index nonunion surgery were associated with the need for a secondary surgery after nonunion repair. Appropriate care of these patients should be aimed at adjusting expectations of unplanned reoperation in the future and potentially enhanced treatment strategies.

Abstract
Tibial fractures represent a great burden of disease globally, being the most common long-bone fracture; smoking is a known risk factor for delayed skeletal healing and post-fracture complications. This systematic review and meta-analysis aims to analyse the effect of smoking on healing of tibial shaft fractures. PubMed, CINAHL, EMBASE, and Cochrane Library databases were searched from inception to March 2021, with no limitation on language, to find relevant research. All observational studies that assessed the association between cigarette smoking and tibial shaft fracture healing in adults (≥18 years) were included. The quality of studies was evaluated using the Newcastle Ottawa Quality Assessment Scale. A random effects model was used to conduct meta-analysis. Tobacco smoking was associated with an increased rate of non-union and delayed union as well as an increase in time to union in fractures of the tibial shaft. Among the 12 included studies, eight reported an increased rate of non-union, three reported delayed union, and five reported an increase in time to union. However, the results were statistically significant in only three studies for non-union, one for delayed union, and two studies for increased time to union. This review confirms the detrimental impact of smoking on tibial shaft fracture healing and highlights the importance of patient education regarding smoking cessation.

Abstract
BACKGROUND This study sought to evaluate the effectiveness of locally developed external fixators (LDEF) as definitive treatment for open tibia diaphyseal fractures (OTDF) in Ivory Coast. METHODS Gustilo I, II, and IIIA OTDFs of patients admitted within 24 hours of injury were prospectively included and treated with LDEF. The rates of union, mal-union, septic complications, as well as the functional results were assessed, in addition to the LDEF construct's integrity. Predictive factors of failure or poor results were assessed. RESULTS Overall, 40 OTDF patients were admitted within 24 hours of injury. Gustilo I, II, and IIIA fractures were observed in three, 13, and 24 patients, respectively. Uneventful fracture healing was obtained in 29 cases, with an average union time of 8.47 months. Mal-union and non-union were registered in three and four cases, respectively. Pin-track infection (PTI) was observed in 13 cases and deep infection in seven. Infection resolved in all patients except four, who developed chronic osteomyelitis. None of the non-unions were associated with an infection. The overall functional result was satisfactory in 32 patients. PTI was the only predictive factor for chronic infection. Biplanar frames, when compared to monoplanar constructs, were associated with a significantly improved functional outcome. CONCLUSION LDEF improved significantly the OTDF management, as it provided better stability and superior fracture healing rates than what is observed with the standard of care in the same environment. PTI remains an essential problem but with, hopefully, limited negative consequences.

Abstract
BACKGROUND Intramedullary nailing is the standard of care for tibial shaft fractures. The risk factors for infectious and/or mechanical complications, notably non-union, remain incompletely understood. The objective of this study was to evaluate risk factors for complications, notably non-union. HYPOTHESIS Active smoking and an initial open wound are independent risk factors for complications. MATERIALS AND METHODS We retrospectively included consecutive patients managed for open or closed tibial shaft fractures by primary intramedullary nailing between 2013 and 2018. We collected data on preoperative factors related to the patient and to the mechanism of injury (age, sex, smoking history, energy of the trauma, open wound), on intraoperative factors (residual interfragmentary gap), and on postoperative factors (early or delayed weight-bearing). We evaluated the associations between these factors and the occurrence of complications, notably non-union, by performing a univariate analysis followed by a multivariate analysis. RESULTS We included 184 patients [mean age, 38.5±17.6 (range, 15-91), 72.2% of males]. One or more complications developed in 28 (15.2%) patients and non-union occurred in 15 (8.1%) patients. There were three significant risk factors for complications: active smoking (OR, 7.93; 95%CI, 2.76-22.7), a residual interfragmentary gap >5mm (OR, 4.92; 95%CI, 1.72-14.02), and an initial open wound (OR,5.16; 95%CI, 1.62-16.43) (p<0.05). The same three factors were significant risk factors for non-union. Energy of the trauma, age, sex, and early or delayed weight bearing were not significantly associated with an excess risk of complications. DISCUSSION Active smoking, a residual interfragmentary gap >5mm, and an initial open wound are risk factors for postoperative complications after intramedullary nailing to treat a tibial shaft fracture. Preventive strategies and specific information could be implemented for these patients. LEVEL OF EVIDENCE IV; single-centre retrospective cohort study.

Abstract
OBJECTIVE The aim of this study is to assess the prevalence of nonunion in patients with tibia fracture and the association between influencing factors and tibia fracture nonunion. METHOD A database searches of PubMed, the Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI), Weipu database, and Wanfang database from inception until June 2019 was conducted. The pooled prevalence, odds ratio (OR), and 95% confidence intervals (CI) were calculated with Stata software. RESULTS In this study, 111 studies involving 41,429 subjects were included. In the study of the relationship between influencing factors and tibia fracture nonunion, 15 factors significantly influenced the fracture union, including > 60 years old, male, tobacco smoker, body mass index > 40, diabetes, nonsteroidal anti-inflammatory drugs (NSAIDs) user, opioids user, fracture of middle and distal tibia, high-energy fracture, open fracture, Gustilo-Anderson grade IIIB or IIIC, Müller AO Classification of Fractures C, open reduction, fixation model, and infection. CONCLUSION The prevalence of nonunion in patients with tibia fracture was 0.068 and 15 potential factors were associated with the prevalence. Closed reduction and minimally invasive percutaneous plate osteosynthesis (MIPPO) have the low risks of nonunion for the treatment of tibial fractures.

Abstract
BACKGROUND Romosozumab is an antibody that binds and inhibits sclerostin, thereby increasing bone formation and decreasing bone resorption. A double-blinded, randomized, phase-2, dose-finding trial was performed to evaluate the effect of romosozumab on the radiographic and clinical outcomes of surgical fixation of tibial diaphyseal fractures. METHODS Patients (18 to 82 years old) were randomized 3:1:1:1:1:1:1:1:1:1 to a placebo or 1 of 9 romosozumab treatment groups. Patients received subcutaneous injections of romosozumab or the placebo postoperatively on day 1 and weeks 2, 6, and 12. The primary outcome was the time to radiographic evidence of healing ("radiographic healing") analyzed after the week-24 assessments had been completed for all patients. RESULTS A total of 402 patients were randomized: 299 to the romosozumab group and 103 to the placebo group. The median time to radiographic healing (the primary outcome) ranged from 14.4 to 18.6 weeks in the romosozumab groups and was 16.4 weeks (95% confidence interval [CI]: 14.6 to 18.0 weeks) in the placebo group, which was not a significant difference. There was also no significant difference in the median time to clinical healing, no relationship between romosozumab dose/frequency and unplanned revision surgery, and no apparent treatment benefit in terms of physical function. The safety and tolerability profile of romosozumab was comparable with that of the placebo. CONCLUSIONS Romosozumab did not accelerate tibial fracture-healing in this patient population. Additional studies of patients at higher risk for delayed healing are needed to explore the potential of romosozumab to accelerate tibial fracture-healing. LEVEL OF EVIDENCE Therapeutic Level I.
