Introduction
The reported rate of nonunion of distal femoral fractures varies in the literature. Several risk factors for nonunion following lateral locked plating (LLP) have been described. We aimed to study the rate of nonunion, and risk factors thereof, in a Swedish population where fragility fractures are common. A secondary aim was to study risk factors for reoperation for any cause.Patients and Methods
We retrospectively reviewed the hospital files and radiographs of all adult patients admitted to our institution with a distal femoral fracture, from 2004 through 2013. In cases treated with LLP, medical comorbidities, fracture characteristics and implant characteristics were analysed as potential risk factors for nonunion, defined as any surgical intervention to improve healing.Results
There were 8 cases (4%, 95%CI: 1.8–8.1%) of nonunion in 191 fractures treated with LLP. Patients with nonunion were younger: 62 vs. 81 years (p?=?0.009) and more commonly had open fractures: 38% vs. 9% (p?=?0.034). No patient 80 years or older had a surgical intervention for nonunion. Lower age was independently associated with reoperation for any cause, but not for nonunion.Discussion
The low rate of nonunion in this study is probably due to the fact that we present data from a complete cohort from a geographic catchment area. Referral centres with a high proportion of young patients with high-energy injuries, may be better suited for studies on risk factors for nonunion, due to higher statistical power. However, results from such institutions may not be generalizable to the more common low-energy fractures. 相似文献2.

Background
The aim of this study was to investigate the postoperative outcomes of cementless Total hip arthroplasty (THA) following failed internal fixation for femoral neck and intertrochanteric fractures.Method
Ninety-six cementless THAs for failed internal fixation after femoral neck fracture (59, group I) and intertrochanteric fracture (37, group II) with a minimum follow-up of 3 years were analyzed. Clinical and radiologic evaluations were performed on all patients.Results
The intraoperative blood loss and operating time were significantly increased in group II (p?=?0.001, p?=?0.001, respectively). Harris hip score at last follow-up was significantly improved in group I (p?=?0.007) but, there were no differences in hospital stay, Koval score at last follow-up, and perioperative complications between both groups. Long femoral stems for diaphyseal fitting were frequently used in group II (32/37, 86%) (p?=?0.001). Radiographically, none of the acetabular cups showed evidence of migration, loosening. All cases showed stable fixation of the femoral stem at last follow-up.Conclusions
Outcomes of cementless THA following failed internal fixation for femoral neck and intertrochanteric fractures were satisfactory; increased intraoperative blood loss, operating time, and requirement of long femoral stem should be considered in the latter type of fracture. 相似文献3.
Objectives
The purpose of this study is to analyze posteromedial fragment morphology using two-dimensional computed tomography fracture mapping and to compare posteromedial fragment morphology in various Schatzker type tibial plateau fractures.Materials & methods
One hundred twenty-seven consecutive AO/OTA B- and C-type tibial plateau fractures were retrospectively analyzed using 2DCT fracture mapping. The posteromedial articular fracture angle and articular surface areas of all fractures with posteromedial fragments were calculated. Based on biomechanical studies, posteromedial fragments with coronal fracture angles >68° were considered amenable for anterolateral stabilization with standardized plating. Kruskall-Wallis non-parametric test was used for statistical comparison of morphological features of posteromedial fragments between the various Schatzker types.Results
Forty-seven out of 127 tibial plateau fractures included a posteromedial fragment. The mean posteromedial articular fracture angle was 44° (range: 2°-90o, standard deviation: 23°). Forty fragments (85%) had a fracture angle of <68°, increasing the risk for insufficient stabilization with standardized anterolateral plating. The mean articular surface area was 34% of the entire tibial plateau (range: 7%–53%, SD: 12%). There were no significant differences in posteromedial fragment morphology between Schatzker type IV, V, and VI fractures.Discussion and conclusion
Posteromedial fragments commonly occur not only in Schatzker type V and VI, but also in Schatzker type IV tibial plateau fractures. Eighty-five percent of tibial plateau fractures with a posteromedial fragment may benefit from non-standard customized lateral plating, or may require an additional medial or posterior surgical approach for fracture-specific fixation to optimize screw purchase and biomechanical stability. 相似文献4.
Objective
To analyse whether early post-operative full weight bearing following syndesmotic ankle fixation affected radiographic outcomes suggestive of diastasis.Design
Retrospective comparative cohort study over a two year period.Setting
Level 1 trauma centrePatients/Participants
152 consecutive patients sustaining an unstable ankle fracture requiring syndesmotic stabilisation were included. Exclusions were 49 patients who had trimalleolar fixation without syndesmosis screws, one patient who had concomitant ankle and talar fracture. Five patients were lost to follow up and eleven patients were followed up in other centres. A total of 86 patients were analysedIntervention
Protected or full weight bearing.Main Outcome Measurement
The primary outcome measure was early diastasis. The secondary outcomes were late diastasis, wound complications and re-operation. Analysis of variance was used for the predictor variable of weight bearing status. We assumed a priori that p values of less than 0.05 were significant.Results
Median age was 36 (IQR 30), with 54 males and 32 females. Median follow up was 12 weeks (IQR 6). There was no significant difference when comparing weight bearing status and change in radiographic measurements intra-operatively compared to 6 and 12 week follow up radiographs (tibiofibular clear space p?=?0.799, tibiofibular overlap p?=?0.733 and medial clear space p?=?0.261).Conclusion
After surgical stabilization of an unstable syndesmotic injury, full weight bearing did not lead to syndesmotic diastasis in the early post-operative period. Full weight bearing is recommended following ankle fixation which includes syndesmotic fixation. 相似文献5.
Background and purpose
The treatment of paediatric distal radius diaphyseal metaphyseal junction (DRDMJ) fractures is a challenge. The purpose of this study was to introduce a new operative approach at the proximal “safe zone” of the posterior interosseous nerve (PIN) to treat paediatric DRDMJ fractures and analyse the safety and efficacy of antegrade elastic stable intramedullary nail (ESIN) fixation.Methods
Thirty paediatric patients with unstable and displaced DRDMJ fractures were treated by antegrade ESIN fixation from November 2015 to September 2017. We created the entrance site at the posterolateral side of the proximal radius and 2?4?cm distal to the articular surface of the radius, using the ESIN to immobilise the fractures. In the study, we reviewed patient demographics, complications, time until removal, and intraoperative time for hardware removal.Results
Complete fracture healing was achieved between 6 and 12 weeks after surgery. Except for 3 patients presenting with irritation of the skin, we did not observe any complications. Radiologically, no secondary displacement, nail migration, loss of fixation, consolidation delay, non-union, or refracture was noted.Conclusions
The antegrade ESIN fixation is a minimally invasive, easy-to-learn, alternative operative method to treat paediatric DRDMJ fractures.Level of evidence

Purpose
Antegrade intramedullary nailing is an alternative for humeral shaft fracture treatment. This surgical technique can be especially demanding in some fracture patterns, leading to problems like malunion and non-union. The purpose of our study is to demonstrate that the use of a nail with cerclage wires could be a safe procedure that facilitate reduction, specially in fractures with abduction of the proximal fragment.Materials and methods
Fifty-six patients were included, from January 2007 to March 2016. In this cohort forty-two patients were females and eighteen males; mean age was sixty-seven (32–89). The fractures were reduced using a cerclage wire through a small lateral or anterior approach, then, antegrade intramedullary nailing was performed. Fracture healing was established by clinical and radiographic evaluation. Shoulder function was assessed using the Constant Score.Results
Fifty-three patients healed (94.6%) adequately. Two patients developed a non-union (3.5%). One patient developed an infection (1.8%). Transient radial nerve palsy was observed in two patients (3.5%). The mean Constant Score at the end of the study was 70 points (range from 34 to 98 points).Conclusions
Surgical treatment of humeral shaft fractures with cerclage wire and intramedullary nailing is a safe technique to improve fracture reduction. The use of cerclage wires leads to better bone contact while minimizing malunions. The rate of non-union in our study is lower than the rate reported in the literature for humeral shaft fractures treated by intramedullary nailing alone. 相似文献7.
Introduction
Multitrauma patients suffering hindfoot fractures, including calcaneal and talar fractures, often result in poor outcomes. However, less is known about the outcomes following midfoot fracture in the mutitrauma population. This study aims to describe the epidemiology of midfoot fractures in multitrauma patients and to compare the outcomes of midfoot and hindfoot fractures in this population.Methods
Data about multitrauma patients (Injury Severity Score >12) sustaining a unilateral midfoot or hindfoot fracture were obtained from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) and from retrospective review of medical records at a major trauma centre. Further outcome data were obtained via a survey using the American Academy of Orthopedic Surgeons Foot and Ankle Score (AAOS FAS) and the 12-item Short Form Health Survey (SF-12).Results
122 multitrauma patients were included; 81 with hindfoot fractures and 41 with midfoot fractures. The median ISS (IQR) was 22 (17–29) and 27 (17–24) for the hindfoot and midfoot groups, respectively (p?=?0.23). Hindfoot and midfoot fractures were commonly associated with intracranial injuries (80.3%), spine injuries (60.7%), ipsilateral lower extremity injuries (24.6%) and pelvic injuries (16.4%). The mean (SD) time to follow up was 4.5 (±2.7) years. There were no differences in mean SF-12 physical (37.97 vs 35.22, p?=?0.33) or mental (46.90 vs 46.67, p?=?0.94) component summary scores between the groups. There were no differences in mean AAOS FAS standard scores (69.3 vs 69.1, p?=?0.97) or shoe comfort scores (median 40 vs 40 p?=?0.18) between the groups.Conclusion
Functional outcomes in multitrauma patients with midfoot or hindfoot fractures were comparable. These findings suggest that midfoot fractures should be treated with the same degree of due diligence as hindfoot fractures in the multitrauma patient. 相似文献8.

Background
Standard radiographs are limited in the evaluation of fracture characteristics and preoperative planning of OTA/AO 43C3 fractures. Therefore, CT imaging is an accepted as a useful method. CT is however expensive and has high radiation, and traction radiographs could be an alternative. This study aimed to compare fracture fragment and comminution zone visualization between traction radiographs and CT and any potentially resulting differences in consecutive treatment and surgical approach recommendations.Methods
Twenty orthopaedic surgeons assessed traction radiographs and CT images of 12 OTA/AO 43C3 type fractures. Each observer was required to identify the anterolateral, posterolateral, and medial malleolus fragments and the lateral, central, and medial shoulder comminution zones. They then had to recommend treatment (nonoperative, ORIF, closed reduction and external fixation, percutaneous screw fixation, or primary tibiotalar arthrodesis) with the best surgical approach (medial, anterolateral, posterolateral, posteromedial, or combined). Intra- and interobserver reliability, correct identification of fracture fragments and comminution zones on both images, and consistency of treatment recommendations and surgical approaches were analyzed.Results
The agreement of each observer’s assessment of the presence or absence of specific fracture fragments and comminution zones was substantially increased for CT as compared to traction radiographs, particularly for the posterolateral (p?=?0.000) and anterolateral fragment (p?=?0.000), and the lateral (p?=?0.000), central (p?=?0.000), and medial shoulder comminution zone (p?=?0.000). The interobserver reliability when assessing the three fracture fragments and comminution zones on the traction radiographs was moderate, whereas it was substantial when assessing these characteristics on CT. The medial malleolus fragment was more often correctly identified on traction radiographs than CT images (p?=?0.001). The ability to correctly identify lateral, central, and medial shoulder comminution zones was higher for CT than traction radiographs (p?=?0.000). The treatment and surgical approach recommendations after traction radiograph and CT evaluation were similar (p?<?0.05).Conclusions
Traction radiographs may be a useful alternative to CT imaging in the preoperative planning of pilon fracture repair. Despite less reliable fracture fragment and comminution zone identification on traction radiographs, treatment recommendations and surgical approach were not influenced. 相似文献9.

Background
This study assessed the surgical outcomes of Lisfranc injuries accompanied by multiple metatarsal fractures. Metatarsal fractures here refers to metatarsal head, neck, and shaft (including shaft fractures accompanied by fractures of the base) fractures, as well as mixed (i.e., segmental fracture) fractures, as seen on imaging studies.Methods
Between 2002 and 2015, one hundred and seventy-six patients were followed-up for a mean of 92 months, including eight patients who underwent secondary arthrodesis due to severe arthritis after ORIF. All the patients underwent surgical fusion (primary partial arthrodesis, PPA; n?=?78) or non-fusion (percutaneous or open reduction and internal fixation, ORIF; n?=?98) procedures and the outcomes were evaluated by clinical examinations, radiography, visual analogue scale (VAS) pain score, the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, the Foot and Ankle Outcome Score (FAOS), and the Short Form (SF)-36 physical and SF-36 mental questionnaires. The parameters between the fusion and non-fusion groups were analyzed by repeated-measures ANOVA. Statistically significant differences between the two groups were then further analyzed using a two-independent-samples t-test.Results
Anatomical reduction was achieved in 161 patients. At the last follow-up, the mean AOFAS score was 74.67 (range: 39–91) in the non-fusion group and 82.79 (range: 67–97) in the fusion group (P?=?0.003). The PPA and ORIF groups differed significantly with respect to the VAS pain score (1.93 vs. 1.21), the SF-36 physical (75.87 vs. 80.90) and mental (75.76 vs. 81.33) components, and the FAOS pain (72.74 vs. 84.06), symptoms (71.87 vs. 82.49), activities of daily life (ADLs: 73.12 vs. 81.54), sport/recreation (sport/rec: 57.99 vs. 73.23), and quality of life (QoL: 79.95 vs. 86.67) components. In the ORIF group, 23 patients had mild/moderate post-traumatic osteoarthritis.Conclusions
With longer and more conservative postoperative management, fusion results in a better outcome than non-fusion in the treatment of Lisfranc injuries accompanied by multiple metatarsal fractures. 相似文献10.

Background
This 10?year retrospective study of the NTDB is the first to describe trends in scapula fracture diagnosis frequency, epidemiology, injury mechanisms and the type of hospital where the condition is treated.Methods
Demographics, ISS scores, hospital data, mechanism of injury, complications, and hospital length of stay were recorded for patients with diagnosed scapula fractures (ICD-9, 811.0) recorded in the NTDB, v7.2 (2002–2012). Mean and standard deviation for continuous variables and proportions for binary variables are calculated.Results
The prevalence of scapula fractures in all patients submitted to the NTDB (2002–2012) was 1.74%. Between 2006–2007, the reported incidence doubled from 1% to 2.2%. There was a predominance of injury to white males (75% and 78% respectively). Forty-one percent were treated at a Level 1 trauma center and had a mean ISS of 20.1 (SD-11.8). Scapula fracture rates declined in patients 0–19 years and increased in the 60–79 and 80+ age groups. The increasing incidence of the aged population is also reflected in the increase of falls as the mechanism of injury in the elderly population.Conclusion
This study is the first to describe a full decade of scapula fracture epidemiology on a national scale. The number of diagnosed scapula fractures increased substantially in the NTDB between 2002-2012. Scapula fractures diagnosed in the geriatric demographic and fractures resulting from falls are both on the rise, whereas the reported incidence is decreasing in the younger demographic. Additionally, fractures as a result of motor vehicle accidents also decreased precipitously during the reported decade. 相似文献11.

Background
It is common practice when placing cannulated screws within the femoral head when treating femoral neck fractures to avoid the thread-forms from crossing the fracture line. Despite the widespread use of cannulated screws in internal fixation of femoral neck fractures, there is no study to our knowledge that describes the ideal length of thread-forms.Purpose
The purpose of this study is to determine the thread length that will maximize purchase within the femoral head while minimizing risk of crossing the fracture line. Additional analysis was conducted to identify factors associated with the maximal possible length of treads in minimally and non-displaced femoral neck fractures.Methods
We performed a retrospective study of all patients treated for a minimally or non-displaced femoral neck fracture from April 1, 2004 through December 31, 2017. Only patients who had received a pre-operative CT or MRI scan were included. Fixation was then templated using radiographs and the distance from the subchondral bone to the fracture line was then measured.Results
The study included 127 patients. The average estimated length of lag screw threads was 33.2?±?6.67?mm, with lower quartile of 29.1?mm and higher quartile of 37.2?mm. The median was 32.0?mm and most frequently encountered estimate was 29?mm. Estimated lag screw size did not differ significantly based on age or BMI, but both height (p?<?0.001) and race (0.04) were positively correlated with estimated lag screw size and males had longer measurements compared to females, 37.2?±?7.0?mm vs 31.4?±?5.7?mm (p?<?0.001), respectively.Conclusion
In conclusion, we propose an additional lag screw thread form with length 26.0?mm to capture 90% of femoral neck fractures. 相似文献12.

Introduction
Tibial pilon fractures are often treated with initial external fixation followed by delayed definitive fixation. It has been postulated that the external fixator pin site may correlate with infection risk. The purpose of this study was to determine whether external fixator pin-site distance from definitive implants impacts the risk of deep infection in pilon fractures.Materials and methods
A retrospective cohort study was completed at a single level 1 trauma center. All patients ages 15–65 who underwent open reduction and internal fixation (ORIF) of a distal tibial fracture (AO/OTA Classification 43) from 2007 to 2013 were included. The final study population was 133 patients. The impact of external fixation pin location (relative to the definitive implant location) on postoperative infection was measured.Results
As a continuous variable, the distance between the closest pin site and plate was 62.1 ± 44.1?mm in the infected cohort and 62.2 ± 49.7?mm in the non-infected cohort (p?=?0.991). Further analysis was performed by grouping the distances into less than 0?mm (i.e. overlapping), >0.0 – 25.0?mm, >25.0 – 50.0?mm, >50.0 – 75.0?mm, >75.0 – 100.0?mm, and >100.0?mm of separation. No significant differences were noted with regards to the risk for infection.Conclusions
Staged care has been shown to be an effective treatment strategy for AO/OTA type 43 fractures. There are many variables to consider when placing an external fixator construct. In this cohort, pin site distance from definitive implant location was not associated with an increase in deep infections.Level of evidence

Background
The main purpose of this study is to introduce our surgical technique and report surgical outcomes for percutaneous cable fixation in the treatment of subtrochanteric femoral fractures.Methods
Between May 2013 and April 2017, 51 patients with subtrochanteric femoral fractures treated with closed intramedullary nailing and percutaneous cable fixation were enrolled in this study. Postoperative angulation, union rate, time from injury to union, and femoral shortening were also evaluated to assess radiologic outcomes. Clinical outcomes, including range of hip flexion, walking ability, and Harris hip score at the last follow-up were evaluated.Results
Average coronal and sagittal angulation after surgery were 0.9 (range 0–5) and 0.3 (range 0–5), respectively. There was no postoperative angulation of more than 5°. Average shortening of the femur at 1-year follow-up was 2.7?mm (range 0–15). Bone union was achieved in 50 patients (98.0%) and average time to union was 18.6 weeks (range 12–48). Hip flexion, walking ability and Harris hip score at the last follow up were 115.6° (90–120), 7.9 (5–9), and 88.3 (65–100), respectively.Conclusion
Percutaneous cerclage cable fixation can provide a greater likelihood of achieving anatomical reduction and increased stability of fracture, while preserving biology around the fracture site. Thus, percutaneous cerclage cable fixation can be an effective surgical technique for the treatment of complex subtrochanteric fractures. 相似文献14.
Introduction
Distal femoral fractures have many of the same challenges as hip fractures, but there has been limited research into outcomes following these. The aim of this study was to assess 30 day mortality following distal femoral fractures in comparison to hip fractures presenting to a single institution Secondary outcomes included risk factors for mortality, post-operative complications and union.Methods
A retrospective case series of all distal femoral fragility fractures in patients over 65, and hip fractures over a 5?year period at a single institution.Results
88 distal femoral fractures and 2837 hip fractures fulfilled the inclusion criteria. In the distal femoral fractures there were 80 females and 8 males with a mean age of 82.4 (range 65–103). The mean age of the hip fractures was 83.7 (range 65–106) and there were 2066 females and 771 males.The overall 30 day mortality for hip fractures was 7.7% and was 9.1% for distal femoral fractures. The risk ratio was 1.1777(95% CI 0.6009–2.3080) (p?=?0.6338). There was no significant difference in 30 day mortality between the two fracture types.Of the 88 distal femoral fractures 75 (85.2%) underwent open reduction internal fixation, 5 (5.7%) intramedullary nail and 8 (9.1%) conservative treatment. 11.4% suffered a medical complication. 9.1% patients required at least 1 further surgical procedure. The union rate was 94.3%. The 1?year mortality was 34.1%.Conclusions
There is no significant difference in 30 day mortality between distal femoral and hip fractures. Distal femoral fractures occur in a complex group of patients that is similar to hip fractures. They have high mortality and complication rates. 相似文献15.

Objective
Fracture line of the sacrum always involves the Zone II region because sacral foramina are anatomically and physiologically weak regions of the sacrum. The purpose of this study is to compare the therapeutic effects of a sacroiliac screw and a minimally invasive adjustable plate (MIAP) for Zone II sacral fractures.Methods
Patients with unilateral Zone II sacral fractures fixed with a unilateral sacroiliac screw or MIAP from August 2009 to January 2016 were recruited into this study and were divided into two groups: group A (sacroiliac screw) and group B (MIAP). Surgical time, blood loss, frequency of intraoperative fluoroscopy, and relative complications were reviewed. Radiographs and CT scans were routinely acquired to evaluate the fracture displacement and reduction quality. Fracture healing was evaluated in the radiographs at each follow-up. Functional outcome was assessed based upon the Majeed scoring system at the final follow-up.Results
Thirty-one patients in group A and thirty-nine patients in group B were included in this study. No significant differences in average surgical time (P?=?0.221) or blood loss (P?=?0.234) were noted between group A and group B. The mean frequency of intraoperative fluoroscopy was 15.74±2.98 in group A and 6.08±1.94 in group B (P?=?0.000). All fractures healed well within four months in all patients, and the healing time exhibited no significant difference between the two groups (P?=?0.579). Satisfactory rates of reduction quality and functional outcome were not statistically different between the two groups (P?>?0.05). The complication rate was 16.13% (5/31) in group A and 5.13% (2/39) in group B (P?=?0.222).Conclusion
MIAP has a fixation effect and exhibits reduction potential for Zone II sacral fractures. Favourable radiographic and functional results could be obtained through the MIAP technique, which is easy to conduct without pre-contouring. Compared with the unilateral S1 sacroiliac screw technique, repeated projections and iatrogenic sacral injury can be avoided. 相似文献16.
Background
In the last decade, the biomechanics of reverse shoulder arthroplasty (RSA) for proximal humeral fractures in the elderly have led to more functional outcomes and greater pain relief. However, its use has also introduced a significant rate of complications. The purpose of this study is to assess the complication rate of RSA in these cases as well as the relationship to ASA score and basic disease history.Methods
We evaluate patients who underwent RSA due to acute proximal humeral fractures at three hospitals from 2010 to 2016. We analyze previous disease and anticoagulant treatment, American Society of Anesthesiologists (ASA) Physical Status Classification, and the transfusion rate to correlate these factors with major and minor postoperative complications at 7, 90, and 365 days.Results
We include 103 patients (104 shoulders) over 65 years of age. Mean age is 77.31?years (62–91), 20 of which are male. The overall rate of complications is 25%, with 17.4% minor and 7.6% major complications. We observe a statistically significant relationship between a higher ASA score (3,4) and major complication at 90 days (p?=?0.024) and a trend (p?=?0.072) towards a higher ASA score with minor complication during the first week. Rheumatoid disease significantly increases major complications at 90 days (p?=?0.037). The transfusion rate is 11.5%.Conclusions
The overall major complication rate of RSA for acute fractures is low in the elderly population. Although, the patient’s history (e.g. previous rheumatoid pathology, neurological diseases, or anticoagulant treatment) as well as their ASA score should be considered before RSA surgery. The higher the ASA score and the presence of rheumatoid disease, leads to a higher rate of major complications during the first 90 days after surgery.Level of evidence

Purpose
To explore the hidden blood loss (HBL) in treatment of extra-articular tibial fractures with plate and intramedullary nail fixation.Methods
We conducted a retrospective study including 209 consecutive patients treated by plate (Group LCP) or intramedullary nail fixation (Group IMN) for extra-articular tibial fractures between January 2015 to December 2017. Demographics, intraoperative data, perioperative laboratory values, transfusion rate, and early complications were collected and analyzed.Results
Of 209 patients, 96 patients fixed with IMN and 113 fixed with LCP. The average HBL was 272.71?±?57.88?ml in Group LCP and 507.66?±?109.81?ml in Group IMN, and there was statistical difference in the HBL between two groups (p?<?0.001). The Hb and Hct loss, surgical duration, and postoperative number of anemic patients in Group IMN were significantly higher than in Group LCP (p?<?0.001), and IMN fixation has a significantly higher rate of transfusion (p?=?0.027), whereas patients in group IMN has significantly less VBL (p?<?0.001), shorter postoperative hospital stay (p?<?0.001), and less superficial infection (p?=?0.014).Conclusions
There was a significant amount of hidden blood loss after reamed intramedullary nail fixation for extra-articular tibial fractures, which was much higher than expected. In view of the morbidity of acute anaemia and transfusion, we suggest that for patients who suffer from extra-articular tibial fractures with multiple injuries, or those with low haemoglobin preoperatively, plates might be more suitable than nail fixation. 相似文献18.

Introduction
Intra-articular distal humeral fractures involving both columns require double-plate fixation. In orthogonal plate fixation, screws from the medial plate reach the radial column, while screws from the dorsolateral plate run posterior–anterior, not creating interdigitation. The Synthes LCP-DHP system has an orthogonal plate configuration that enables dorsolateral plating with support, as the radial and ulnar columns are linked via interdigitation of the distal screws. We hypothesized that the transcondylar screw from the posterolateral plate, which interdigitates with screws from the medial plate, enables more rigid stabilization of orthogonal plating in distal humeral AO type C fractures.Methods
A previous study reported the biomechanical properties of orthogonal plate fixation using an AO type 13-C2.3 intra-articular fracture model with a 1-cm supracondylar gap using artificial bones (Kudo et al., Injury, 2016). We performed a biomechanical study of the dorsolateral plate with support, and inserted one 2.7-mm locking screw through the support in the lateral-to-medial direction, creating interdigitation of the distal screws. A 0–200?N axial load was applied separately to the radial and ulnar columns. We calculated the stiffness of both columns, and the anterior displacement of the condylar fragment. We compared the biomechanical properties of orthogonal plating with versus without interdigitation.Results
There were no significant differences between the two groups in radial or ulnar axial compression. The ulnar column was stiffer than the radial column in both groups. There were no significant differences between groups in the angular displacements of the capitellum or trochlea. The capitellum moved more anteriorly than the trochlea during axial compression in both groups.Discussion
The radial and ulnar columns were linked via interdigitation of the distal screws by adding one transcondylar screw from the dorsolateral plate, which did not affect radial column stiffness or capitellar anterior movement under axial compression. In the orthogonal configuration, axial compression induced more anterior displacement of the capitellum than the trochlea, which may induce secondary fragment or screw dislocation on the dorsolateral plate or nonunion at the supracondylar level.Conclusions
The transcondylar screw from the dorsolateral plate did not affect axial compression of the radial column or capitellar anterior displacement. 相似文献19.
