Low energy open ankle fractures in the elderly: Outcome and treatment algorithm

Experience With Immediate Internal Fixation Combined With Primary Wound Closure in Gustilo-Anderson Type IIIA Open Ankle Fractures

Open ankle fractures, especially Gustilo-Anderson type III fractures are challenging to manage with controversy over the "best" or "superior" treatment strategy. This study aimed to evaluate the treatment outcome of immediate internal fixation combined with primary wound closure in the management of Gustilo-Anderson type IIIA open ankle fractures. We retrospectively assessed the outcomes of thirty-two patients treated using immediate internal fixation combined with primary wound closure with a minimum follow-up of twenty-four months. At the median follow-up of 38 months, the mean American Orthopaedic Foot and Ankle Society scale score was 87.22 ± 4.05. The physical component summary score of Short-Form 36 Health Status Survey was 66.63 ± 11.42 and the mental component summary score was 67.31 ± 7.20. Range of motion of Ankle/Foot injured side was 64.56 ± 4.30 degrees, and range of motion of Ankle/Foot uninjured side was 72.31 ± 3.12 degrees. Visual analog pain scale score was 1.5 ± 0.88 at rest and 3.09 ± 1.17 during activity. According to American Orthopaedic Foot and Ankle Society scale score, the rate of excellent and good outcomes was 90.6%. Postoperative complications were documented, comprising 2 (6.4%) cases of infection, 5 (15.6%) cases of wound skin necrosis, 1 (3.2%) case of postoperative ankle traumatic arthritis, and 1 (3.2%) case requiring reoperation due to suboptimal fibula fracture reduction. The study results demonstrated that immediate internal fixation combined with primary wound closure for Gustilo-Anderson type IIIA open ankle fractures achieve good functional outcomes and lower complication rates.

Open Ankle Fractures in Older Individuals: A Multi-center Study

The purpose of this study is to identify demographics, etiology, comorbidities, treatment, complications, and outcomes for older patients with open ankle fractures. Patients ≥60 years old who sustained an open ankle fracture between January 1, 2004 and March 31, 2014 at 6 Level 1 trauma centers were retrospectively reviewed. Univariate analysis using chi-squared or Student's t test was performed to identify associations between preoperative variables and 2 postoperative outcomes of interest: amputation and 1-year mortality. Multivariate analysis was performed using stepwise logistical regression to identify independent predictors of postoperative amputation and 1-year mortality. Of the 162 total patients, the most common mechanism of injury was a ground-level fall (51.9%). The most common fracture types were bimalleolar fractures (52.5%) followed by trimalleolar fractures (26.5%), with 41.5% of the fractures classified as Gustilo Anderson Classification Type 2 and 38.6% classified as Type 3A. The average number of surgeries required per patient was 2.1. Complications included: 15.4% superficial infection rate, 9.9% deep infection rate, and 9.3% amputation rate. The 1-year mortality rate was 13.6% and the overall mortality rate was 25.9%. Male gender and fracture type were found to be independent predictors for amputation after surgery (p = .009, .005, respectively). Older age and having diabetes were independent predictors for 1-year mortality after surgery (p = .021, .005 respectively). Overall, open ankle fractures in older individuals were associated with high rates of amputation and mortality.

Association of sociodemographic characteristics with the timeliness of surgery for patients with open tibial fractures

BACKGROUND

The American College of Surgeons recommends operative debridement of open tibial fractures within 24 h of presentation. It is unknown what the compliance rates are with this recommendation and what factors contribute to delays to operation.

METHODS

To determine the characteristics associated with delays to operation for open tibial fractures, we conducted a retrospective cohort study utilizing American College of Surgeons Trauma Quality Improvement Program data from 2017 to 2021. Individuals aged 18 and older presenting to a trauma center with an open tibial fracture were included. Associations were determined with a hierarchal regression model nesting patients within facilities.

RESULTS

Of the 24,102 patients presenting to 491 trauma centers, 66.3 % identified as White, 21.7 % as Black, 1.5 % as Asian, 1.1 % as American Indian, and 10.6 % as Other race. In total, 15.8 % identified as Hispanic. Patients were most often men (75.9 %) and privately insured (47.6 %). The median time to OR was 10.2 h (IQR 4.4-17.7) with 84.6 % receiving surgery within 24 h. In adjusted analyses, Black and American Indian patients had 5.5 % (CI 1.3 %-9.9 %) and 17.8 % (CI 2.2 %-35.8 %) longer wait times, respectively, and a decreased odds of receiving surgery within 24 h (AOR 0.85, CI 0.8-0.9; AOR 0.69, CI 0.5-0.9) when compared to White patients. Female patients had 6.5 % (CI 3.0 %-10.2 %) longer wait times than men. Patients with Medicaid had 5.5 % (CI 1.2 %-9.9 %) longer wait times than those with private insurance. Greater time to OR was associated with increasing age (p < 0.001), increasing injury severity (p < 0.001), and the presence of altered mentation (p < 0.001).

CONCLUSION

We identified longer wait times to operative irrigation and debridement of open tibial fractures for Black and American Indian patients, women, and those with Medicaid. The implementation of health equity focused quality metrics may be necessary to achieve equity in trauma care.

Open ankle fractures in the elderly: predisposing factors and the associated mortality

The purpose of this study was to investigate the independent effect of open ankle fractures on postoperative mortality and to identify factors leading to open ankle fractures in the elderly population. This is a retrospective case-control study of 1,045 patients aged 65 years and older, with ankle fractures undergoing surgical fixation between 2010 and 2020 at three medical centers (Levels 1-2). A logistic regression analysis was used to identify risk factors for open fractures. Propensity score matching and survival analysis were used to measure the hazard of mortality attributable to open versus closed ankle fractures. There were 128 (12.2%) patients with open ankle fractures. Patients with open ankle fractures were more likely to be older, to be active smokers (OR = 1.7, p = 0.049), and tended to have a higher number of medical comorbidities including hypertension (OR = 2, p = 0.006) and chronic kidney disease (OR = 2.9, p = 0.005). Open ankle fractures were, independently of comorbid conditions and age, associated with higher risk of mortality (HR = 1.7, p = 0.03).

Consensus on managing open ankle fractures in the frail patient

Aims

Ankle fractures are common injuries and the third most common fragility fracture. In all, 40% of ankle fractures in the frail are open and represent a complex clinical scenario, with morbidity and mortality rates similar to hip fracture patients. They have a higher risk of complications, such as wound infections, malunion, hospital-acquired infections, pressure sores, veno-thromboembolic events, and significant sarcopaenia from prolonged bed rest.

Methods

A modified Delphi method was used and a group of experts with a vested interest in best practice were invited from the British Foot and Ankle Society (BOFAS), British Orthopaedic Association (BOA), Orthopaedic Trauma Society (OTS), British Association of Plastic & Reconstructive Surgeons (BAPRAS), British Geriatric Society (BGS), and the British Limb Reconstruction Society (BLRS).

Results

In the first stage, there were 36 respondents to the survey, with over 70% stating their unit treats more than 20 such cases per year. There was a 50:50 split regarding if the timing of surgery should be within 36 hours, as per the hip fracture guidelines, or 72 hours, as per the open fracture guidelines. Overall, 75% would attempt primary wound closure and 25% would utilize a local flap. There was no orthopaedic agreement on fixation, and 75% would permit weightbearing immediately. In the second stage, performed at the BLRS meeting, experts discussed the survey results and agreed upon a consensus for the management of open elderly ankle fractures.

Conclusion

A mutually agreed consensus from the expert panel was reached to enable the best practice for the management of patients with frailty with an open ankle fracture: 1) all units managing lower limb fragility fractures should do so through a cohorted multidisciplinary pathway. This pathway should follow the standards laid down in the "care of the older or frail orthopaedic trauma patient" British Orthopaedic Association Standards for Trauma and Orthopaedics (BOAST) guideline. These patients have low bone density, and we should recommend full falls and bone health assessment; 2) all open lower limb fragility fractures should be treated in a single stage within 24 hours of injury if possible; 3) all patients with fragility fractures of the lower limb should be considered for mobilisation on the day following surgery; 4) all patients with lower limb open fragility fractures should be considered for tissue sparing, with judicious debridement as a default; 5) all patients with open lower limb fragility fractures should be managed by a consultant plastic surgeon with primary closure wherever possible; and 6) the method of fixation must allow for immediate unrestricted weightbearing.

Patient Characteristics and Outcomes of Geriatric Ankle Fractures: Open Fracture Is the Key Risk Factor for Complications and Functional Decline

OBJECTIVES

To determine whether open (O) or closed (C) geriatric ankle fractures had different patient characteristics or outcomes.

METHODS

.

DESIGN

Retrospective cohort study.

SETTING

Urban Level 1 trauma center.

PATIENT SELECTION CRITERIA

Patients, age 60 years and older, who underwent operative fixation of a rotational ankle fracture (OTA/AO 44A-C) between January 2012 and September 2021.

OUTCOME MEASURES AND COMPARISONS

Morbidity, defined as 90-day reoperation, 90-day readmission, or loss of mobility, as well as 1-year mortality compared between patients with closed and open fractures.

RESULTS

The open cohort was older (75 years vs. 68 years; P = 0.003) but had similar Charlson comorbidity indices (4.6 O vs. 4.0 C; P = 0.323) and preinjury rates of independent ambulation (70.4% O vs. 80.9% C; P = 0.363). There were higher rates of 1-year mortality (11% vs. 0%; P < 0.001), deep infection (14.8% vs. 3.9%; P = 0.019), and loss of mobility (64.7% vs. 23.0%; P < 0.001) in the open cohort. Multivariate regression identified open fracture as an independent predictor of 90-day reoperation (OR: 20.6; P = 0.022) and loss of mobility (OR: 5.1; P = 0.011).

CONCLUSIONS

Despite having comorbidities and preinjury function similar to the closed geriatric ankle fracture cohort, open ankle fracture was independently predictive of greater loss of mobility. Nearly two-thirds of geriatric patients with open ankle fractures experienced a decline in functional independence, compared with 1 in 4 of those with closed fractures. Open fracture was associated with higher rates of deep infection, reoperation, and 1-year mortality.

Clinical outcome of open ankle fractures in patients above 70 years of age

BACKGROUND

Open fractures of the ankle are complex injuries requiring multidisciplinary input and are associated with significant morbidity and mortality. However, data on the clinical outcomes of open ankle fracture management in patients older than 70 is minimal.

AIM

To evaluate the clinical outcomes following open ankle fracture management in patients older than 70. Our secondary aim is to look at predictors of poor outcomes.

METHODS

Following local research and audit department registration, 22 years of prospectively collated data from an electronic database in a district general hospital were assessed. All patients older than 70 years of age with an open ankle fracture requiring surgical intervention were identified. Demographic information, the nature, and the number of surgical interventions were collated. Complications, including surgical site infection (SSI), venous thromboembolic events (VTEs) during hospital stay, and mortality rate, were reviewed.

RESULTS

A total of 37 patients were identified (median age: 84 years, range: 70-98); n = 30 females median age: 84 years, range: 70-97); n = 7 males median age: 74 years, range: 71-98)) who underwent surgical intervention after an open ankle fracture. Sixteen patients developed SSIs (43%). Superficial SSIs (n = 8) were managed without surgical intervention and treated with antibiotics and regular dressing changes. Deep SSIs (n = 8; 20%) required a median of 3 (range: 2-9) surgical interventions, with four patients requiring multiple washouts and one patient having metalwork removed. VTE incidence was 5% during the hospital stay. Eight patients died within 30 d, and mortality at one year was 19%. The 10-year mortality rate was 57%. The presence of a history of stroke, cancer, or prolonged inpatient stay was found to be predictive of lower survivorship in this population (log-rank test: cancer P = 0.008, stroke P = 0.001, length of stay > 33 d P = 0.015). The presence of a cardiac history was predictive of wound complications (logistic regression, P = 0.045). Age, number of operations, and diabetic history were found to be predictive of an increase in the length of stay (general linear model; age P < 0.001, number of operations P < 0.001, diabetes P = 0.041).

CONCLUSION

An open ankle fracture in a patient older than 70 years has at least a 20% chance of requiring repeated surgical intervention due to deep SSIs. The presence of a cardiac history appears to be the main predictor for wound complications.

Temporizing cast immobilization is a safe alternative to external fixation in ankle fracture-dislocation while posterior malleolar fragment size predicts loss of reduction: a case control study

Background

To determine if temporizing cast immobilization is a safe alternative to external fixator (ex-fix) in ankle fracture-dislocations with delayed surgery or moderate soft-tissue injury, we analysed the early complications and re-dislocation rates of cast immobilization in relation to ex-fix in patients sustaining these injuries.

Methods

All skeletally mature patients with a closed ankle fracture-dislocation and a minimum 6-months follow-up treated between 2007 and 2017 were included. Baseline demographics, comorbidities, injury description, treatment history and complications were assessed.

Results

In 160 patients (94 female; mean age 50 years) with 162 ankle fracture-dislocations, 35 underwent primary ex-fix and 127 temporizing cast immobilizations. Loss of reduction (LOR) was observed in 25 cases (19.7%) and 19 (15.0%) were converted to ex-fix. The rate of surgical site infections (ex-fix: 11.1% vs cast: 4.6%) and skin necrosis (ex-fix: 7.4% vs cast: 6.5%) did not differ significantly between groups (p = 0.122 and p = 0.825). Temporizing cast immobilization led to an on average 2.7 days earlier definite surgery and 5.0 days shorter hospitalization when compared to ex-fix (p < 0.001). Posterior malleolus fragment (PMF) size predicted LOR with ≥ 22.5% being the threshold for critical PMF-size (p < 0.001).

Conclusion

Temporizing cast immobilization was a safe option for those ankle fracture-dislocations in which immediate definite treatment was not possible. Those temporized in a cast underwent definite fixation earlier than those with a fix-ex and had a complication rate no worse than the ex-fix patients. PMF-size was an important predictor for LOR. Primary ex-fix seems appropriate for those with ≥ 22.5% PMF-size.

Trial registration

The study does not meet the criteria of a prospective, clinical trial. There was no registration.

Efficacy of hook-type locking plate and partially threaded cancellous lag screw in the treatment of displaced medial malleolar fractures in elderly patients

INTRODUCTION

Traditionally, partially threaded cancellous lag screws (PTCS) are used for most medial malleolar fractures but are often challenging to execute in elderly patients because of the high risk of postoperative complications. Limited literature explores whether hook-type locking compression plates (LCPs) reliably offer better outcomes than PTCS in elderly patients. We aimed to compare the midterm radiologic and clinical outcomes between hook-type LCP and PTCS for medial malleolar fractures in an elderly population.

METHODS

We included 258 patients, aged 65 years and above, treated with either a hook-type locking plate (hook LCP group: 121 patients) or PTCS (screw group: 137 patients), and with follow-ups of at least 36 months in this retrospective study. Radiographic assessments included the union rate and interval to fracture union. Clinical assessment included the postoperative complications and revision procedures.

RESULTS

Although a significantly higher rate of comminuted fractures was observed in the hook LCP group than in the screw group (p < .001), no significant difference in the union rate was observed between the two groups (hook LCP group: 93.4% vs. screw group: 89.8%, p = .151), and a significantly shorter interval to union was observed in the hook LCP group (10.2 ± 7.0 vs. 12.3 ± 6.7 weeks, p = .015). There was a trend toward a lower rate of complications, including revision procedures, in the hook LCP group than in the screw group (19.9% vs. 28.5%, p = .107 and 6.6% vs. 13.8%, p = .074).

CONCLUSION

Hook-type LCP may be an alternative option for treating medial malleolar fractures with comminution in elderly patients.

Management of Open Ankle Fractures in Elderly Patients With a Fibula Nail is a Safe and Reliable Technique

BACKGROUND

Ankle fractures are becoming more common in the elderly and their management is frequently challenging. There is increasing evidence of good outcomes following fibula nail fixation in the management of ankle fractures. The use of a fibula nail in open fractures comes with potential advantages such as minimal soft tissue dissection, early rehabilitation, and decreased wound complications. We aimed to assess their use in the management of open ankle fractures in the elderly.

METHODS

A review of patients aged 60 years or older with an open ankle fracture treated with a fibular nail at a major trauma center was conducted. All patients were managed with joint Orthopaedic and Plastic Surgical input to determine their optimal management. Functional outcome scores, postoperative complications, and re-operation rates were determined.

RESULTS

Fifteen patients were identified with a mean age of 76 years. Patient-reported outcomes (Olerud and Molander Score) were calculated in 73% of patients. Our results demonstrated excellent outcome scores (>91) in 1 patient, good outcome scores (61-90) in 7 patients, and fair outcome scores (31-60) in 3 patients. There were no postoperative complications or re-operations within our study group.

CONCLUSION

This article is the largest series presenting the outcomes of fibula nails in the management of open ankle fractures in elderly patients. We conclude that it can be used as a treatment option to safely manage open ankle fractures in the elderly. It provides a stable fixation, early weight-bearing, low risk of postoperative complications while maintaining good patient-reported functional outcomes.

Open ankle fractures: Factors influencing unplanned reoperation

INTRODUCTION

Ankle fractures are amongst the most common open fracture injuries presenting to major trauma centres (MTC) and their management remains a topic of debate. Incidence is increasing particularly in the elderly population however the optimal surgical approach and risk factors for unplanned reoperation remain scarce. We therefore conducted a retrospective case study to analyse our institution's outcomes as well as identify risk factors for early unplanned reoperation.

MATERIALS AND METHODS

Sixty-five consecutive open ankle fractures were identified using our institutional database between July 2016 and July 2020. Medical records and operation notes were reviewed to identify patient age at injury, Sex, co-morbidities and other co-morbidities, fracture configuration, extent of soft tissue injury, fixation type and post-operative complications. The data was categorised into four groups for analysis, 1) age, 2) AO-OTA classification 3) Sex 4) Gustilo-Anderson grade. Statistical analysis was undertaken to identify predictors of unplanned reoperation.

RESULTS

The mean age of patients at the time of injury was 60.8. Unplanned reoperation rate was 17.5%. Age and Gustilo-Anderson classification grade were both statistically significant predictors of unplanned reoperation. AO-OTA classification, Sex and Diabetes were not statistically significant factors associated with unplanned reoperation.

CONCLUSION

Age and quality of soft tissue envelope are significant risk factors for unplanned reoperation. Patients with these risk factors may benefit from an alternative surgical approach.

Open lower limb fractures in the elderly

OBJECTIVE

The aim of this study was to assess the outcomes of open lower limb fractures in patients aged 65 and over. The primary outcome was mortality at 30 days, and the secondary outcome was reoperation.

METHODS

This study retrospectively identified patients aged 65 and over, presenting with an open tibia or ankle fracture, over a two-year period. Patient demographics, injury characteristics and surgical interventions were documented. The 30-day and one-year mortality was recorded, as well as any complications encountered.

RESULTS

There were 88 patients included in the study, with a mean age of 78 years and 66% of patients were female. Of this cohort, 67 patients (76%) had low energy injuries and 64 patients (73%) had Gustillo-Anderson type IIIB injuries. Treatment consisted of a one-stage surgical procedure in 49 patients (56%) and a two-stage procedure in 37 patients (42%), with two patients dying before definitive treatment. Primary wound closure was performed in 23 patients (26%), four patients (5%) had a split skin graft alone, 35 patients (40%) had local flaps, 21 patients (24%) were managed with free flaps and three patients (3%) had primary below knee amputations. The 30-day mortality rate was 10%, the one-year mortality rate was 19% and the reoperation rate was 8%.

CONCLUSION

Open lower limb fractures in the elderly are a life and limb threatening injury, with a similar demographic and mortality profile to hip fracture. This study demonstrates that limb salvage can be achieved in 93% of cases, with treatment performed as a one-stage procedure in 56% of cases.

Open tibia/fibula in the elderly: A retrospective cohort study

The incidence of open tibia/fibula fractures in the elderly is increasing, but current national guidelines focus on the aggressive treatment of high-energy injuries in younger patients. There is conflicting evidence regarding whether older age affects treatment provision and outcomes in open fractures. The aim of this study was to determine if elderly patients are sustaining a different injury to younger patients and how their treatment and outcomes differ. This may have implications for future guidelines and verify their application in the elderly. In this retrospective single centre cohort study (December 2015-July 2018), we compared the injury characteristics, operative management and outcomes of elderly (≥65 years) and younger (18-65 years) patients with open tibia/fibula fractures. An extended cohort examined free flap reconstruction. In total, 157 patients were included. High-energy injuries were commoner in younger patients (88% vs 37%; p<0.001). Most were Gustilo-Anderson IIIb in both age groups. Elderly patients waited longer until debridement (21:19 vs 19:00 h) and had longer inpatient stays (23 vs 15 days). There was no difference in time to antibiotics, operative approach or post-operative complications. Despite the low-energy nature of elderly patients' injuries, the severity of soft tissue insult was equivalent to younger patients with high-energy injuries. Our data suggest that age and co-morbidities should not prohibit lower limb reconstruction. The current application of generic guidelines appears suitable in the elderly, particularly in the acute management. We suggest current management pathways and targets be reviewed to reflect the greater need for peri-operative optimisation and rehabilitation in elderly patients.

Male sex, Gustillo-Anderson type III open fracture and definitive external fixation are risk factors for a return to the or following the surgical management of geriatric low energy open ankle fractures

INTRODUCTION

Open ankle fractures in geriatric (age > 60 years) patients are a source of significant morbidity and mortality. Surgical management includes plate and screw fixation (ORIF), retrograde hindfoot nail (HFN), definitive external fixation (ex-fix) and below knee amputation. However, each modality poses unique challenges for this population. We sought to identify predictors of unplanned OR and short-term mortality after geriatric open ankle fractures managed by our service.

MATERIALS AND METHODS

In an IRB-approved protocol, we evaluated patients over 60 years of age managed for a low energy open ankle/distal tibia pilon fracture by trauma fellowship-trained surgeons from a single academic department that covers two level I trauma centers. Our primary outcome was an unplanned return to the OR. Secondary outcomes were a 90-day "event", defined as an all-cause hospital readmission or mortality, and 1-year mortality. Differences with a p-value < 0.1 measured on univariate analysis were evaluated using a multivariable logistic regression to identify independent outcome predictors.

RESULTS

A total of 113 (60 ORIF, 36 HFN, 11 ex-fix, 6 amputations) were performed. Cohort mean age was 75.2 ± 9.8 years, and 31 patients (27.4%) were male. Mean age-adjusted charlson comorbidity index was 5.5 ± 2.0. Significant independent predictors of an unplanned return to the OR were male sex (OR 4.4, 95% CI 1.3 to 15.4), Gustilo Type III open fracture (OR 4.9, 95% CI 1.5 to 17.5) and ex-fix (OR 15.6, 95% CI 2.7 to 126.3). Independent predictors of a 90-day "event" were walker/minimal ambulation (OR 3.5, 95% CI 1.3 to 10.4), surgical site infection (OR 4.8, 95% CI 1.8 to 13.8) and reduced BMI (OR 0.9, 95% CI 0.9 - 0.99), while independent predictors of 1-year mortality were age (OR 1.1, 95% CI 1.003 to 1.2), ACCI (OR 1.4, 95% CI 1.02 to 2.0) and walker/minimal ambulator (OR 7.5, 95% CI 1.7 to 53) CONCLUSIONS: Host factors, particularly pre-operative mobility, were most predictive of 90-day event and 1-year mortality. Only definitive external fixation was found to influence patient morbidity as a significant predictor of unplanned OR. However, no surgical modality had any influence on short-term readmission or survival.

Short-term outcome of isolated lateral malleolar fracture treatment is independent of hospital trauma volume or teaching status: a nationwide retrospective cohort study

Introduction

In light of current discussions about centralisation and teaching in medicine, we wanted to investigate the differences in in-hospital outcomes after surgical treatment of isolated ankle fractures, taking into account high-volume centres (HVCs) and low-volume centres (LVCs) and teaching procedures.

Methods

A retrospective analysis of malleolar fractures recorded in a National Quality Assurance Database (AQC) from the period 01-01-1998 to 31-12-2018 was carried out. Inclusion criteria were isolated, and operatively treated lateral malleolar fractures (ICD-10 Code S82.6 and corresponding procedure codes). Variables were sought in bivariate and multivariate analyses. A total of 6760 cases were included. By dividing the total cases arbitrarily in half, 12 HVCs (n = 3327, 49%) and 56 LVCs (n = 3433, 51%) were identified.

Results

Patients in HVCs were younger (48 vs. 50 years old), had more comorbidities (26% vs. 19%) and had more open fractures (0.48% vs. 0.15%). Open reduction and internal fixation was the most common operative treatment at HVCs and LVCs (95% vs. 98%). A more frequent use of external fixation (2.5% vs. 0.55%) was reported at HVCs. There was no difference in mortality between treatment at HVCs and LVCs. A longer hospitalisation of 7.2 ± 5 days at HVCs vs. 6.3 ± 4.8 days at LVCs was observed. In addition, a higher rate of complications of 3.2% was found at HVCs compared to 1.9% at LVCs. The frequency of teaching operations was significantly higher at HVCs (30% vs. 26%). Teaching status had no influence on mortality or complications but was associated with a prolonged length of stay and operating time.

Conclusion

We found significant differences between HVCs and LVCs in terms of in-hospital outcomes for ankle fractures. These differences could be explained due to a more severely ill patient population and more complex (also open) fracture patterns with resulting use of external fixation and longer duration of surgery. However, structural and organisational differences, such as an extended preoperative stays at HVCs and a higher teaching rate, were also apparent. No difference in mortality could be detected.

Orthoplastic Management of Open Midfoot Injuries: Is Functional Limb Salvage Possible?

High energy open midfoot injuries are uncommon but devastating injuries. A combination of complex fracture dislocations and soft tissue injury patterns render reconstruction challenging. The aim of this study was to assess the surgical and patient reported outcomes following orthoplastic management of open midfoot injuries in a Major Trauma Center. A retrospective review of all open midfoot fractures admitted to our unit between January 2015 and December 2016 was undertaken. Demographics, operative details, complications, additional surgeries, and patient reported outcomes in the form of EQ-5D and Enneking scores were collected. Fifteen patients were identified (13 male, mean age 39.2 years). One patient underwent amputation at initial debridement and 8 required additional debridement. Of these 8 patients, 3 had an amputation during their index admission. In the limb salvage group (11 patients), definitive soft tissue cover involved free flaps in 6 patients, split skin graft in 3 patients, and delayed primary closure in 2 patients. Definitive orthopedic treatment was internal fixation in 8 and external fixation in 3 patients. Two patients required a Masquelet procedure for bone loss. One patient had a toe amputation and 1 had a below knee amputation for deep infection. The median EQ-5D score was 66 (interquartile range 43), and the median Enneking score was 20.5 (interquartile range 9). Limb salvage following open midfoot fractures is technically possible in most cases, however this often involves multiple procedures and the outcomes are variable and difficult to predict. Patients should be carefully counseled, and amputation considered in all such cases.

Ankle fractures in the elderly: Current concepts

Ankle fractures remain the third most common musculoskeletal injury in the elderly population. The presence of osteoporosis, significant multiple comorbidities and limited functional independence makes treatment of such injuries challenging. Early studies highlighted high rates of post-operative complications and poor outcomes after surgical intervention. With advances in surgical techniques and a greater understanding of multi-disciplinary team (MDT)-driven peri-operative care and rehabilitation, evidence now appears to suggest improved outcomes for operative management. Approaches must be adapted according to co-morbidities, baseline function and patient wishes. This review article aims to discuss contemporary treatment strategies and the complex challenges associated with the management of the elderly ankle fracture.

The importance of anatomical reduction in the functional outcome of open ankle fractures

INTRODUCTION

Whilst closed ankle fracture injuries are common, well characterized and have treatment guidelines derived from the literature, open ankle fractures are rare and are not well studied. The few studies that exist are from the developed First World and these well resourced circumstances are not available in most parts of the world. The purpose of this prospective study was to assess the functional outcomes of open ankle fractures and the factors associated with their outcome in an adult population in rural South Africa.

METHODS

This prospective study was done at a referral hospital in a rural and semi-rural part of South Africa during the study period from January 1, 2013 until April 30, 2019 and was a retrospective chart review of 59 adult patients who sustained open ankle fractures. Pre-, peri- and postoperative factors in the chart review were assessed for each patient. Twenty-one patients were available for follow-up and were reviewed at least 6 months post injury for a functional assessment using the American Orthopedic Foot and Ankle Society Score (AOFAS).

RESULTS

The average AOFAS was 68,2 out of 100 (fair outcome). The lowest score recorded was 38 (one patient) and the highest score 95 (two patients). Nine patients presented with a poor outcome (<60), six with a fair outcome (60-79), two with a good outcome (80-89) and four with an excellent outcome (90-100). The only significant finding, using a Fisher's exact test, indicated that anatomical reduction of the fracture lead to a fair, good or excellent outcome compared to a non-anatomical reduction leading to a poor functional outcome (p = 0,046).

CONCLUSIONS

Our results showed that open ankle fractures are serious injuries with a very variable outcome when managed in a rural or semi-rural setting and that anatomical reduction is required to achieve an optimal functional outcome.

Ankle fractures in patients over age 55 years: Predictors of functional outcome

OBJECTIVES

To identify predictors of functional outcomes following treatment of ankle fracture in patients 55 years or older.

SETTING

Level 1 Trauma Center.

PATIENTS/PARTICIPANTS

Four hundred twenty-nine patients with torsional ankle fractures (44A-C): 233 patients (54%) were ages 55 to 64, 25% were between the ages 65 and 74; 21% were 75 years or older.

INTERVENTION

Operative or nonoperative management of ankle fracture.

MAIN OUTCOME MEASURE

Early complications were assessed for all patients after minimum of 6 months, and functional outcome scores as assessed by the Foot Function Index (FFI; n = 166, 39%) and Short Musculoskeletal Function Assessment (SMFA; n = 168, 39%) after median 57 months follow-up.

RESULTS

Surgical management was elected in 67% of patients. Nonoperative management became more common with advancing age and was associated with fewer unplanned operations (12% vs 3%, P < .01) and complications (21% vs 13%, P = .07). African American race was associated with worse pain on the FFI (P = .002) and BMI was associated with worse (higher) scores on all categories of the FFI and SMFA (all P < .05). Diabetes, neuropathy, and mental illness were also predictive of worse scores on various categories of both surveys. Assistive device use or nonambulatory status at the time of injury was associated with worse disability/dysfunction, activity, and mobility scores on both the FFI and SMFA (all P > 15, P < .05). Sex, Hispanic ethnicity, tobacco use, open fracture, dislocation, fracture pattern, and operative management were not independent predictors in this regression model.

CONCLUSIONS

Baseline health and ambulatory capacity at injury were more predictive of outcomes following ankle fracture than were fracture characteristics or type of treatment.

Early Definitive Care Is as Effective as Staged Treatment Protocols for Open Ankle Fractures Caused by Rotational Mechanisms: A Retrospective Case-Control Study

OBJECTIVES

To compare immediate internal fixation with primary wound closure to temporary fixation/stabilization with delayed fixation and wound closure protocols for management of open ankle fractures.

DESIGN

Retrospective case-control study.

SETTING

Level 1 trauma center.

PATIENTS

Eighty-eight consecutive patients who presented with a Gustilo-Anderson type I, II, or IIIa open ankle fracture to a single center.

INTERVENTION

Patients were divided into 2 cohorts: either immediate internal fixation with primary wound closure (EARLY) or temporary fixation/stabilization with delayed fixation and wound closure (STAGED) due to practice differences of the attending surgeons.

MAIN OUTCOME MEASURES

Infection, length of stay, number and type of operations, and clinical measures. We also assessed the 2 groups with regard to demographics and radiographic classification.

RESULTS

Overall, incidence of infection was 6 (6.8%) with no significant difference between patients treated with EARLY versus STAGED protocols. The EARLY cohort had a significantly shorter length of hospital stay, fewer number of reoperations but similar clinical outcomes for pain, ambulation, and radiographic evidence of osteoarthritis for patients followed for >12 months.

CONCLUSION

Our study showed that early definitive treatment compared with a staged protocol for Gustilo-Anderson type I, II, and IIIa open ankle fractures has similar rates of infection, shorter hospital stay, fewer surgical interventions, and similar clinical outcomes.

Fibular nails for open and closed ankle fractures: Results from a non-designer level I major trauma centre

AIM

To evaluate the outcome of a fibular nail in the treatment of open and closed unstable ankle fractures in a non-designer centre.

METHODS

In a retrospective cohort study, a total of 39 ankle fractures (14 open and 25 closed) treated with a locking fibular nail were evaluated between 2012 and 2015 in a non-designer level I major trauma centre. Post-operative radiographs were analysed to assess the quality of reduction (McLennan and Ungersma marking system), fracture union and complications. Three patient reported outcome scores (Olerud and Molander score (OMAS), American Association of Orthopaedic Surgeons (AAOS) foot and ankle score and 12-Item Short Form Survey (SF-12)) were collected to obtain an overall measure of the patient's physical and mental outcome.

RESULTS

The adequacy of reduction data was available for 38 of 39 cases; 33 (87%) achieved good, 3 (8%) fair and 2 (5%) poor ratings, based on the McLennan and Ungersma marking system. Thirty-five (12 open and 23 closed) patients were available for initial follow-up. Five (14.3%) of 35 had documented complications (2 of 12 in the open cohort and 3 of 23 in the closed cohort). All fibular fractures treated with the fibular nail went on to unite. Twenty-three (66%) of 35 patients were available at 1-year follow-up for measurement of objective outcome. The combined mean OMAS for both groups was 53.7 (0-85) with statistically better results (59.5 (25-85) vs. 37.3 (0-75)) in favour of the closed versus open injuries, respectively. The mean AAOS score was also statistically better for the closed group than the open, 70.3 (30-95) versus 46.6 (20-77), respectively. The mean SF-12 score (physical component) was 40 (21.6-52.4) in the closed group versus 36.1 (19.4-51.5) in the open group; the mean mental component was 42.5 (26.6-54.3) in the closed group versus 38.8 (28.4-60.5) in the open group, these however were not statistically different.

CONCLUSION

Fibular nails are an effective alternative for the treatment for both closed and open unstable ankle fractures with soft tissue compromise.

Transarticular tibiotalocalcaneal nailing versus open reduction and internal fixation for treatment of the elderly ankle fracture: protocol for a multicentre, prospective, randomised controlled trial

INTRODUCTION

Ankle fractures are common in the elderly population. Surgical fixation is technically challenging and often results in complications due to high rates of osteoporosis and vascular disease. Open reduction and internal fixation (ORIF) often requires prolonged periods of non-weight bearing increasing the risks of complications. Tibiotalocalcaneal (TTC) nailing has been suggested as an alternative to ORIF which allows immediate weight bearing, and is suggested to result in fewer complications. This study aims to compare the two surgical techniques in the elderly population with ankle fractures.

METHODS AND ANALYSIS

The study will be a multicentre, prospective, randomised controlled trial comparing ORIF to TTC nailing in 110 patients with ankle fractures aged 50 or above with a Charlson Comorbidity Index of greater than or equal to four. Participants and assessors will not be blinded to intervention. The primary outcome measure will be overall complication rate. Secondary outcomes include length of hospital stay, mobility at discharge, discharge destination, the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot score, the Olerud-Molander Ankle Score, mortality rate, rate of secondary surgical interventions and number of blood transfusions required postoperatively. Our null hypothesis is that there is no clinically significant difference in the primary outcome measure between the two treatment groups.

ETHICS AND DISSEMINATION

The study has been approved by Metro South Hospital and Health Services Human Research Ethics Committee (EC00167) (reference number HREC/17/QPAH/351).

DISCUSSION

Completion of this trial will provide evidence on the effectiveness of TTC nailing versus ORIF in treatment of the elderly ankle fracture. If TTC nailing is found to result in superior outcomes, this trial has the capacity to change current clinical practice.
