The additional value of weight-bearing and gravity stress ankle radiographs in determining stability of isolated type B ankle fractures.

GOAL: The aim of this study is to investigate whether weight-bearing and gravity stress radiographs have additional value in predicting concomitant deep deltoid ligamentous (DDL) injury in case of isolated Weber type B fibular fractures. This may help to make the clinically relevant distinction between unstable fractures and fractures that can be treated conservatively. METHODS: In this prospective cohort study, 90 patients with an isolated type B ankle fracture, without a medial or posterior fracture, and a medial clear space (MCS) < 6 mm on the regular mortise (RM) view were included. In all patients, an additional gravity stress (GS) view and an MRI scan were performed. Furthermore, in 51 patients, an additional weight-bearing (WB) radiograph was performed. The MCS and superior clear space (SCS) measurements of these radiographs were compared with MRI findings to measure sensitivity and specificity in excluding deep deltoid ligament (DDL) rupture. RESULTS: The mean MCS on the RM view was 3.32 mm (1.73-5.93) compared to 4.75 mm (2.33-10.40) on the GS view and 3.18 mm (1.93-6.9) on the WB radiograph. MRI showed a high-grade or complete deltoid ligament tear in 25 (28%) patients. Using an MCS cut-off value of ≥ SCS + 2 mm, the RM view showed 0% sensitivity and 97% specificity in diagnosing a DDL rupture. Both the GS view (with MCS ≥ SCS + 3 mm as cut-off value) and the WB radiograph (with cut-off value MCS ≥ SCS + 2 mm) showed 6% sensitivity and 100% specificity. CONCLUSION: The gravity stress and weight-bearing radiograph can accurately exclude DDL injury. They might have extra value in addition to the conventional mortise view in assessing the stability of isolated type B ankle fractures. This helps in deciding whether patients should be selected for operative or safe conservative treatment.

The value of radiologic diagnostics in evaluating deltoid integrity in isolated type B ankle fractures: a systematic review of the literature.

INTRODUCTION: Excluding deep deltoid ligament (DDL) rupture in isolated type B ankle fractures is crucial in the decision-making process for surgical or conservative treatment. There is no consensus about the most accurate radiologic diagnostic test to determine medial injury. The aim of this study is to systematically review the literature concerning radiologic diagnostics that evaluate medial injury in adult patients with isolated type B ankle fractures. METHODS: The electronic databases PubMed, Embase, Web of Science, COCHRANE Library, and Emcare were searched to identify studies published from January 1990 to December 2020 concerning sensitivity and specificity of diagnostic tests that evaluate medial injury in patients with an isolated type B ankle fracture. For inclusion, comparison to a reference test was required to provide results in terms of sensitivity, specificity, and preferably positive predictive value and negative predictive value RESULTS: This review included 8 studies. Ultrasound showed the highest sensitivity of 100% and a specificity between 90 and 100% for detecting DDL rupture. Gravity stress radiographs showed a sensitivity of 71-100% and a specificity between 88 and 92%. The mortise, external rotation stress test, and MRI had lower sensitivity and specificity values, between 65 and 88%. CONCLUSION: The most accurate and available methods for diagnosing deltoid integrity seem to be the ultrasound and the GS radiograph. Further research is needed to confirm the results of this review.

Fibular displacement does not predict instability in type B ankle fractures.

INTRODUCTION: Despite the wide prevalence of ankle fractures, no consensus exists on the most accurate radiologic diagnostic tool to indicate medial ligament injury in isolated type B distal fibular fractures. The aim of this study was to evaluate the value of the fibular fracture displacement in predicting medial clear space widening on the gravity stress radiographs, as a parameter of fracture instability. METHODS: This retrospective cohort study included 192 patients with an isolated type B fibular fracture, for which a regular mortise and gravity stress radiograph were made in our hospital between January 2014 and December 2019. On the regular mortise and lateral radiographs, the medial clear space (MCS), superior clear space (SCS), anteroposterior and lateral fibular displacement were measured. On the gravity stress radiograph, the MCS and SCS were measured. Instability was defined as MCS ≥ SCS + 3.0 mm on the gravity stress radiograph. A receiver operating characteristic (ROC) curve was constructed to evaluate the predictive value of the fibular displacement. RESULTS: Of the 192 included patients, 55 (29%) patients had instable ankle fractures. In predicting instability, fibular displacement demonstrated an area under the curve (AUC) of 0.68 (95% confidence interval 0.60-0.77) and a correlation coefficient of 0.41 with MCS. CONCLUSION: Fibular displacement on regular mortise view is a poor predictor of instability in type B fibular fractures. It should not be advised to use the fracture displacement as parameter for medial injury and thus for operative treatment.

Long-term outcome in operatively and non-operatively treated isolated type B fibula fractures.

PURPOSE: Type B fibula fractures are the most common type of ankle fractures. Generally, surgical repair is advised for unstable fractures and non-operative treatment for stable fractures. However, evidence on long-term functional outcome of both treatment regimens is lacking. Aim of this study is to compare the long-term outcome in function and pain between patients with an isolated type B fibula fracture treated non-operatively and surgically. MATERIAL & METHODS: In this retrospective cohort study, all consecutive patients aged between 18 and 75 years, treated non-operatively or surgically between January 2008 and December 2015 for a distal fibula fracture at the level of the syndesmosis without an additional medial or posterior fracture and with a medial clear space ≤6 mm were included. All eligible patients received a questionnaire, composed of the Olerud-Molander Ankle Score (OMAS), the American Orthopaedic Foot and Ankle Society ankle-hindfoot score (AOFAS), the Euroqol-5D (EQ-5D) for quality of life and the Visual Analogue Scale (VAS) for pain sensation. With a mean follow-up of 5.3 years, 229 patients were included. For all aspects of the questionnaire, there was no significant difference between non-operative and operative treatment in outcome of function and pain: the EQ-5D score was respectively 0.8 vs. 0.9 (p = 0.72), mean VAS score 0.8 vs. 1.3 (p = 0.09), OMA score 84 vs. 84 (p = 0.98) and for the AOFAS 93 vs. 90 (p = 0.28). 33% of the patients who had surgery had revision surgery for implant removal because of persistent pain complaints. In 3% of the surgically treated patients, a wound infection required intravenous antibiotic treatment. In the non-operatively treated cohort, one patient developed a deep venous thrombosis in the fractured leg. CONCLUSION: According to results of this study, in adult patients with an isolated distal fibula and medial clear space ≤6 mm, without proven instability these fractures can safely be treated non-operatively, while avoiding risks and costs of surgery and preserving good long-term outcome in terms of pain and function.

Functional outcome of implant removal following fracture fixation below the level of the knee: a prospective cohort study.

AIMS: The aim of this study was to evaluate the functional outcome in patients undergoing implant removal (IR) after fracture fixation below the level of the knee. PATIENTS AND METHODS: All adult patients (18 to 75 years) undergoing IR after fracture fixation below the level of the knee between November 2014 and September 2016 were included as part of the WIFI (Wound Infections Following Implant Removal Below the Knee) trial, performed in 17 teaching hospitals and two university hospitals in The Netherlands. In this multicentre prospective cohort, the primary outcome was the difference in functional status before and after IR, measured by the Lower Extremity Functional Scale (LEFS), with a minimal clinically important difference of nine points. RESULTS: A total of 179 patients were included with a median age of 50 years (interquartile range (IQR) 37 to 60), of whom 71 patients (39.7%) were male. With a median score of 60 before IR (IQR 45 to 72) and 66 after IR (IQR 51 to 76) on the LEFS, there was a statistically significant improvement in functional outcome (p < 0 .001). A total of 31 surgical site infections (17.3%) occurred. CONCLUSION: Although IR led to a statistically significant improvement of functional outcome, the minimal clinically important difference was not reached. In conclusion, this study shows that IR does not result in a clinically relevant improvement in functional outcome. These results, in combination with the high complication rate, highlight the importance of carefully reviewing the indication for IR. Cite this article: Bone Joint J 2019;101-B:447-453.

The diagnosis and treatment of isolated type B fibular fractures: Results of a nationwide survey.

INTRODUCTION: In isolated Weber B fractures (type B fibular fractures), ruling out instability is critical for safe conservative treatment. In fractures without evident medial injury, additional diagnostics like MRI scan or gravity stress test should be done to differentiate between a stable and unstable fracture. The aim of the current study is to gain more insight in current practice and treatment of type B fractures by Dutch trauma- and orthopaedic surgeons. MATERIALS & METHODS: In December 2017 and January 2018, 559 trauma surgeons were invited by email to join an online survey. This survey consisted of questions regarding diagnostics and treatment of isolated distal fibula fractures. Also, respondents were asked to state their preferred treatment of eight separate cases. RESULTS: In total, 161 surgeons participated, covering 68 different hospitals in the Netherlands. Of them, 32.0% treat more than 30 ankle fractures a year. Based on regular mortise radiographs, 13.6% of the respondents chose surgical treatment in case of a medial clear space (MCS) > 4 mm, 33.8% in case of a MCS > 6 mm and 45.5% in case of a MCS > 4 mm in addition to the MCS ≥ superior clear space + 1 mm. Moreover, 18.2% make use of additional diagnostics (43.9% repeat mortise view after a week, 16.6% weight bearing radiograph, 8.6% gravity stress view, 7.9% exorotation radiograph, 6.5% MRI scan, 0.7% ultrasound, 16.8% other) and 8% establishes their decision not based on the mortise radiograph. Fibular dislocation of ≥ 2 mm was used as an indication for surgical treatment by 69%. Of them, 56% decides to treat surgically in these cases, even with proven medial stability. CONCLUSION: Many surgeons treat type B fibular fractures with a MCS > 4 mm at mortise view surgically, even without proven medial injury. Rarely, additional diagnostics as MRI or gravity stress test are performed in cases with a MCS 4-6 mm. Consequently many stable ankle fractures are treated operatively unnecessarily.

Treating open lower limb fractures successfully; thoughts and current practice on therapy and centralization in The Netherlands.

INTRODUCTION: The British Orthopedic Association (BOA) and British Association of Plastic, Reconstructive and Aesthetic Surgeons (BAPRAS) updated the evidence-based guidelines for the treatment and care of open lower limb fractures (BOAST 4). Following this, a Dutch version has been developed. The main points are multidisciplinary care, planning, and treatment of these injuries. Early osteosynthesis (within 7-14 days) combined with soft-tissue coverage results in more efficient care and less complications. AIM: To study the variation in treatment and thoughts among trauma, orthopedic, and plastic surgeons. MATERIALS AND METHODS: In this cross-sectional study 94 surgeons (57 trauma, 23 plastic, and 14 orthopedic surgeons) working at 46 centers completed an online questionnaire, consisting of 5 demographic, 14 hospital-related, 8 BOAST 4-related, and 2 centralization-related questions. RESULTS: There was a strong agreement among surgeons about the best moment for multidisciplinary consultation, which was before initial debridement, while in practice, this often does not occur. All surgeons agreed that the initial debridement should be performed immediately by any surgeon, but not solely by trainees. Plastic surgeons responded that the definitive stabilization and wound cover should not exceed 7 days, while half of the trauma and orthopedic surgeons agreed that it should not exceed 14 days. Finally, most surgeons agreed that Gustilo 3 fractures should be centralized. However, there was disagreement on the need for centralization of Gustilo 2 fractures. DISCUSSION: Surgeons agree on better and earlier multidisciplinary treatment of open lower limb fractures and the centralization of Gustilo 3 fractures.

Functional bracing treatment for stable type B ankle fractures.

BACKGROUND: In general, stable type B ankle fractures are treated conservatively with cast immobilization or a walking boot during six weeks. Some disadvantages of casting are joint stiffness, muscle wasting and lack of comfort. This study was designed to evaluate whether functional treatment with a removable brace is a safe and more comfortable alternative. MATERIAL AND METHODS: Randomized controlled trial. In the period March 2013 - May 2015, 44 patients visiting the emergency department due to a stable type B ankle fracture were included. During the first week both groups received a splint. After one week the patients were randomized: one group received a cast, the other a removable brace. For outcome Olerud & Molander Ankle Score, Visual Analogue Score for comfort and pain, American Academy of Orthopaedic Surgeons (AAOS) Foot and Ankle score questionnaire, EuroQol-5D and range of motion were used. RESULTS: 44 patients participated (21 cast, 23 brace). There were no differences in baseline characteristics. After 6 weeks, VAS for comfort (cast vs brace; 5.74 vs 7.21; p = 0.02) and total range of motion (40° vs 49°; p = 0.00) showed significant differences in favour of the brace. VAS pain (3.15 vs 2.05; p = 0.16), OMA-score (51.75 vs 61.32; p = 0.22) en EuroQoL-5D (7.26 vs 6.74; p = 0.33) did not show significant differences. Week 52 showed no significant differences at OMA-score (89.29 vs 96.18; p = 0.16), EuroQoL-5D (6.00 vs 5.35; p = 0.15), VAS pain (1.07 vs 0.82; p = 0.69) and AAOS score (91.71 vs 96.06; p = 0.21). No complications occurred in both groups. CONCLUSION: Functional bracing showed significant differences for the VAS comfort score and range of motion at 6 weeks compared to casting. After a year no significant differences were found. Treatment with a brace is a safe and more comfortable option for stable type B ankle fractures.

Routine versus on demand removal of the syndesmotic screw; a protocol for an international randomised controlled trial (RODEO-trial).

BACKGROUND: Syndesmotic injuries are common and their incidence is rising. In case of surgical fixation of the syndesmosis a metal syndesmotic screw is used most often. It is however unclear whether this screw needs to be removed routinely after the syndesmosis has healed. Traditionally the screw is removed after six to 12 weeks as it is thought to hamper ankle functional and to be a source of pain. Some studies however suggest this is only the case in a minority of patients. We therefore aim to investigate the effect of retaining the syndesmotic screw on functional outcome. DESIGN: This is a pragmatic international multicentre randomised controlled trial in patients with an acute syndesmotic injury for which a metallic syndesmotic screw was placed. Patients will be randomised to either routine removal of the syndesmotic screw or removal on demand. Primary outcome is functional recovery at 12 months measured with the Olerud-Molander Score. Secondary outcomes are quality of life, pain and costs. In total 194 patients will be needed to demonstrate non-inferiority between the two interventions at 80% power and a significance level of 0.025 including 15% loss to follow-up. DISCUSSION: If removal on demand of the syndesmotic screw is non-inferior to routine removal in terms of functional outcome, this will offer a strong argument to adopt this as standard practice of care. This means that patients will not have to undergo a secondary procedure, leading to less complications and subsequent lower costs. TRIAL REGISTRATION: This study was registered at the Netherlands Trial Register (NTR5965), Clinicaltrials.gov ( NCT02896998 ) on July 15th 2016.

Open reduction and internal fixation of posterior malleolar fractures using the posterolateral approach.

AIMS: Involvement of the posterior malleolus in fractures of the ankle probably adversely affects the functional outcome and may be associated with the development of post-traumatic osteoarthritis. Anatomical reduction is a predictor of a successful outcome. The purpose of this study was to describe the technique and short-term outcome of patients with trimalleolar fractures, who were treated surgically using a posterolateral approach in our hospital between 2010 and 2014. PATIENTS AND METHODS: The study involved 52 patients. Their mean age was 49 years (22 to 79). There were 41 (79%) AO 44B-type and 11 (21%) 44C-type fractures. The mean size of the posterior fragment was 27% (10% to 52%) of the tibiotalar joint surface. RESULTS: Reduction was anatomical in all patients with a residual step in the articular surface of ≤ 1 mm. In nine of the C-type fractures (82%), the syndesmosis was stable after fixation of the posterior fragment and a syndesmosis screw was not required. Apart from one superficial wound infection, there were no wound healing problems. At a mean radiological follow-up of 34 weeks (seven to 131), one patient with a 44C-type fracture had widening of the syndesmosis which required further surgery. CONCLUSION: We conclude that the posterolateral surgical approach to the ankle gives adequate access to the posterior malleolus, allowing its anatomical reduction and stable fixation: it has few complications. TAKE HOME MESSAGE: Fixation of the posterior malleolus in trimalleolar fractures can be easily done via the posterolateral approach whereby anatomical reduction and stable fixation can be reached due to adequate visualisation of the fracture.

Reconstruction plates for midshaft clavicular fractures: A retrospective cohort study.

BACKGROUND: For the fixation of displaced midshaft clavicular fractures different plates are available, each with its specific pros and cons. The ideal plating choice for this lesion remains subject to ongoing discussion. Reconstruction plates are cheap and easily bendable, but their strength and stability have been questioned. The aim of this study was to evaluate the failure rate of reconstruction plates in the fixation of clavicular fractures. MATERIALS AND METHODS: A multicenter, retrospective cohort study of all consecutive patients with a displaced, midshaft clavicular fracture (Robinson type 2a/2b) treated with a 3.5-mm reconstruction plate between 2006 and 2013 were evaluated. The primary outcome measure was reoperation rate due to implant failure. Secondary outcome measures were nonunion, symptomatic malunion and elective plate removal. RESULTS: One hundred and eleven patients were analyzed. During a median follow-up of 8 months, 14 patients (12.6%) had implant failure, of which 7 (6.3%) required a reoperation. Three nonunions (2.7%) and no symptomatic malunions occurred. Plate removal was indicated in 37.8% of patients because of implant irritation. DISCUSSION: The incidence of reoperation due to implant failure following clavicular plate fixation with a reconstruction plate is 6.3%. Although comparison with other plate types is difficult since rates in literature vary greatly, reoperation rates in other plates are reported around 2-3%, suggesting that reconstruction plates have a higher incidence of implant failure warranting reoperation. Therefore, especially in patients with known risk factors for complications (e.g. smoking, osteoporosis, comminuted fractures), a stronger plate than a reconstruction plate should be considered. LEVEL OF EVIDENCE: Level IV. Retrospective study.

Long-term functional and radiographic outcomes in 243 operated ankle fractures.

BACKGROUND: Large comparative studies that have evaluated long-term functional outcome of operatively treated ankle fractures are lacking. This study was performed to analyse the influence of several combinations of malleolar fractures on long-term functional outcome and development of osteoarthritis. METHODS: Retrospective cohort-study on operated (1995-2007) malleolar fractures. Results were assessed with use of the AAOS- and AOFAS-questionnaires, VAS-pain score, dorsiflexion restriction (range of motion) and osteoarthritis. Categorisation was determined using the number of malleoli involved. RESULTS: 243 participants with a mean follow-up of 9.6 years were included. Significant differences for all outcomes were found between unimalleolar (isolated fibular) and bimalleolar (a combination of fibular and medial) fractures (AOFAS 97 vs 91, p = 0.035; AAOS 97 vs 90, p = 0.026; dorsiflexion restriction 2.8° vs 6.7°, p = 0.003). Outcomes after fibular fractures with an additional posterior fragment were similar to isolated fibular fractures. However, significant differences were found between unimalleolar and trimalleolar (a combination of lateral, medial and posterior) fractures (AOFAS 97 vs 88, p < 0.001; AAOS 97 vs 90, p = 0.003; VAS-pain 1.1 vs 2.3 p < 0.001; dorsiflexion restriction 2.9° vs 6.9°, p < 0.001). There was no significant difference in isolated fibular fractures with or without additional deltoid ligament injury. In addition, no functional differences were found between bimalleolar and trimalleolar fractures. Surprisingly, poor outcomes were found for isolated medial malleolar fractures. Development of osteoarthritis occurred mainly in trimalleolar fractures with a posterior fragment larger than 5 %. CONCLUSIONS: The results of our study show that long-term functional outcome is strongly associated to medial malleolar fractures, isolated or as part of bi- or trimalleolar fractures. More cases of osteoarthritis are found in trimalleolar fractures.

Incidence and clinical relevance of tibiofibular synostosis in fractures of the ankle which have been treated surgically.

In this retrospective cohort study, we analysed the incidence and functional outcome of a distal tibiofibular synostosis. Patients with an isolated AO type 44-B or C fracture of the ankle who underwent surgical treatment between 1995 and 2007 were invited for clinical and radiological review. The American Orthopaedic Foot and Ankle Society score, the American Academy of Orthopaedic Surgeons score and a visual analogue score for pain were used to assess outcome. A total of 274 patients were available; the mean follow-up was 9.7 years (8 to 18). The extent of any calcification or synostosis at the level of the distal interosseous membrane or syndesmosis on the contemporary radiographs was defined as: no or minor calcifications (group 1), severe calcification (group 2), or complete synostosis (group 3). A total of 222 (81%) patients were in group 1, 37 (14%) in group 2 and 15 (5%) in group 3. There was no significant difference in incidence between AO type 44-B and type 44-C fractures (p = 0.89). Severe calcification or synostosis occurred in 21 patients (19%) in whom a syndesmotic screw was used and in 31 (19%) in whom a syndesmotic screw was not used.(p = 0.70). No significant differences were found between the groups except for a greater reduction in mean dorsiflexion in group 2 (p = 0.004). This is the largest study on distal tibiofibular synostosis, and we found that a synostosis is a frequent complication of surgery for a fracture of the ankle. Although it theoretically impairs the range of movement of the ankle, it did not affect the outcome. Our findings suggest that synostosis of the distal tibiofibular syndesmosis in general does not warrant treatment.

Radiographic fracture features predicting failure of internal fixation of displaced femoral neck fractures.

INTRODUCTION: Fixation-related complications of displaced femoral neck fractures treated by internal fixation are accompanied by high mortality and morbidity. The aim of this study is to investigate the pre- and postoperative radiographic fracture characteristics in relation to patient age and the occurrence of reoperation caused by fixation failure. METHODS: The preoperative radiographs of all patients presenting with a proximal femur fracture between January 2004 and December 2012 were retrospectively assessed for fracture type and dislocation (AP and lateral view). Patients with a displaced femoral neck fracture treated by closed reduction and internal fixation were included. The postoperative radiographs were assessed on adequate fracture reduction and correct position of the implant. Patient characteristics and outcome in terms of occurrence of fixation failure (implant breakout, non-union) and reoperation rate were recorded. RESULTS: Hundred and-forty-nine patients were admitted with a displaced femoral neck fracture and treated by internal fixation. Fixation failure was seen in 34 (23%) patients; 9 patients suffered from osteonecrosis. In total, 37 (25%) patients underwent reoperation caused by fixation-related complications. Taking the different age categories into account, 44% of the patients >75 years suffered fixation failure compared with 17% of the patients <65 years. Postoperative incorrect reduction, with persisting dorsoventral dislocation and/or lack of medial support resulted in reoperation in 37% of the patients, compared to 19% reoperations in patients with adequate reduction. CONCLUSION: The results of this study show that patient age and fracture reduction are important predictors for reoperation. In the preoperative treatment plan, patient age should be taken into account and surgeons should strive for anatomical reduction. Patients over 75 should always undergo arthroplasty. In patients aged 65-75, conversion to arthroplasty should be strongly considered if anatomical reduction is impossible.

Interobserver variation in classification of malleolar fractures.

OBJECTIVE: Classification of malleolar fractures is a matter of debate. In the ideal situation, a classification system is easy to use, shows good inter- and intraobserver agreement, and has implications for treatment or research. MATERIAL AND METHODS: Interobserver study. Four observers distributed 100 X-rays to the Weber, AO and Lauge-Hansen classification. In case of a trimalleolar fracture, the size of the posterior fragment was measured. Interobserver agreement was calculated with Cohen's kappa. Agreement on the size of the posterior fragment was calculated with the intraclass correlation coefficient. RESULTS: Moderate agreement was found with all classification systems: the Weber (K = 0.49), AO (K = 0.45) and Lauge-Hansen (K = 0.47). Interobserver agreement on the presence of a posterior fracture was substantial (K = 0.63). Estimation of the size of the fragment showed moderate agreement (ICC = 0.57). CONCLUSION: Classification according to the classical systems showed moderate interobserver agreement, probably due to an unclear trauma mechanism or the difficult relation between the level of the fibular fracture and syndesmosis. Substantial agreement on posterior malleolar fractures is mostly due to small (<5 %) posterior fragments. A classification system that describes the presence and location of fibular fractures, presence of medial malleolar fractures or deep deltoid ligament injury, and presence of relevant and dislocated posterior malleolar fractures is more useful in the daily setting than the traditional systems. In case of a trimalleolar fracture, a CT scan is in our opinion very useful in the detection of small posterior fragments and preoperative planning.

Triage Revised Trauma Score change between first assessment and arrival at the hospital to predict mortality.

OBJECTIVE: To assess among seriously injured accident victims whether change of the Triage Revised Trauma Score (T-RTS) between first assessment and arrival at the hospital independently predicts mortality. DESIGN: Prospective cohort study. METHODS: The study analysed data on 507 trauma patients with multiple injuries and with a Hospital Trauma Index-Injury Severity Score (HTI-ISS) of 16 or higher, who were presented directly by ambulance services to the Accident & Emergency Department of the University Medical Centre Utrecht (the Netherlands) in 1999 and 2000. RESULTS: Compared to non-intubated patients whose T-RTS remained unchanged (reference category), the mortality risk was 3.1 times higher [95% confidence interval (CI): 1.5-6.3, p = 0.001] for patients with deteriorating T-RTS, 2.9 times higher (95% CI: 1.3-6.5, p < 0.001) for patients who had an initially good T-RTS but were nevertheless intubated and 5.7 times higher (95% CI: 3.6-9.0, p < 0.001) for patients who had an initially poor T-RTS and were intubated. These associations were independent of factors that could be assumed to have a direct effect on T-RTS, that is intravenous therapy, oxygen administration and being attended to by a mobile medical team at the scene of the accident. Along with T-RTS change, more advanced age was associated with a higher mortality risk. CONCLUSION: Intubation and a deteriorating T-RTS between the time of the accident and patient's arrival at the hospital are powerful independent predictors of mortality after hospitalisation. Together with advanced age, a deteriorating T-RTS should be the main aspect guiding the preclinical procedures.

[The adverse effects of smoking on healing of open tibial fractures]. / Ongunstige effecten van roken op de genezing van gecompliceerde tibiafracturen.

OBJECTIVE: Survey of the influence of smoking on the healing of open tibial fractures. DESIGN: Retrospective. METHOD: During the period 1 January 1994 to 31 December 2000, 168 patients were treated at the Department of Surgery (University Medical Center Utrecht, the Netherlands) due to an open tibial fracture; 118 patients with 125 fractures were included in the study. On the basis of their smoking behaviour, patients were classified as 'non-smokers' or 'smokers'. For all of the patients it was ascertained whether or not complications had occurred during treatment. Whether the fracture had consolidated was determined on the basis of clinical and radiological criteria. RESULTS: Seventy-two (61%) patients were non-smokers and 46 were smokers. The non-smokers had 77 open tibial fractures and the smokers 48. Initial therapy was identical and wound infections occurred with similar incidences in both groups. However, there was a statistically significant difference in the incidence of osteitis between both groups: 7 (9%) times in the non-smokers and 13 (27%) times in smokers (p = 0.04). The mean time to consolidation was 26 weeks for non-smokers and 33 weeks for smokers (p = 0.04). Smokers remained longer in hospital and underwent more re-operations. CONCLUSIONS: Smoking was negatively associated with the healing of open tibial fractures. In smoking patients, the time to consolidation was on average statistically significantly longer and they suffered more from osteitis.

[Adverse effects if smoking on healing of bones and soft tissues]. / Rauchen ist nachteilig für die Heilung von Knochen und Weichteilen.

This article reviews the current body of knowledge on the adverse effects of smoking on soft-tissue and bone healing, with emphasis on tibial fractures in combination with severe soft-tissue injury. The pathophysiological effects are multidimensional, including arteriolar vasoconstriction, cellular hypoxia, demineralisation of bone, and delayed revascularisation. Several animal and clinical studies have been published about the negative effects of smoking on bone metabolism and fracture healing. These studies show that smokers have a significantly longer time to clinical union than non-smokers and a higher incidence of non-union. The negative effects of smoking gained increased interest among plastic and microvascular surgeons, because smokers have been shown to suffer higher rates of flap failure, tissue necrosis, and haematoma formation. Especially smokers presenting with an open tibial fracture will suffer the negative effects of their smoking behaviour, because these fractures are inextricably bound up with soft-tissue injury. Their fractures will need a significantly longer time to heal than in non-smokers, and will have a higher incidence of non-union. If microvascular surgery is to be performed, persistent smoking significantly increases the rate of postoperative complications, with wound infection, partial flap necrosis, and skin graft loss being more common. Cessation of smoking has both short- and long-term beneficial effects. Nowadays, there is strong evidence to be very insistent that patients presenting with a (open) tibial fracture should refrain from smoking immediately to promote bone healing and to lower the complication rate. In case of elective reconstructive procedures, patients should refrain from smoking at least 4 weeks before surgery. In both situations, cessation should continue during the full rehabilitation period.

Grade III open tibial fractures: functional outcome and quality of life in amputees versus patients with successful reconstruction.

The purpose of this study was to assess the long-term functional outcome and the quality of life of patients who were treated for a (Gustilo) Grade III open tibial fracture. We included 43 patients with successful limb salvage (group A) and 21 amputees (group B). The groups were similar with regard to age, sex, and Injury Severity Score (ISS). The functional outcome was scored using the "Guides to the Evaluation of Permanent Impairment". To compare quality of life we used the Nottingham Health Profile (NHP), the SF-36, and a questionnaire especially designed for this study. The mean lower extremity impairment (AMA) of patients in group A was 17.6%, compared to 73.5% for patients in group B. The results with both NHP and SF-36 show that patients in both groups have more problems in most categories than a healthy reference group. With the NHP, the difference in score was largest for the categories of pain, mobility, energy and sleep. The SF-36 scores correlated well with the NHP scores. No significant difference was found between the two groups. This type of injury has an enormous impact on every aspect of life--irrespective of the chosen treatment. A significant difference in lower extremity impairment is found between patients with a successful reconstruction and those who are amputees. However, the quality of life was shown to be the same.
