Ankle fractures in the elderly: Current concepts

Fractures of the peroneal malleolus: Current concepts

Ankle fractures represent up to 9% of all fractures, with an increased incidence in the elderly population. Among these fractures, isolated fractures of the lateral malleolus are the most common, representing 65-70% of all cases. The therapeutic decision-making primarily relies on the stability of the ankle ring, considering it stable if affected at one point and unstable if two or more points are affected. Surgical treatment focuses on restoring the length of the fibula, joint reconstruction, stabilizing the syndesmosis, and providing a stable fixation. It is crucial to rule out associated injuries that may influence therapeutic management. This article reviews the evaluation and management of lateral malleolus fractures, proposes a decision-making algorithm, and examines several fibular fixation options.

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.

Epidemiology & management of complex ankle fractures in the United Kingdom: A multicentre cohort study

BACKGROUND

Patient factors are known to contribute to decision making and treatment of ankle fractures. The presence of poor baseline mobility, diabetes, neuropathy, alcoholism, cognitive impairment, inflammatory arthritis or polytrauma can result in a higher risk of failure or complications. Limited evidence is available on the optimum management for this challenging cohort of patients herein described as complex ankle fractures. This UK multicentre study assessed and evaluated the epidemiology of ankle fractures complicated by significant comorbidity and patient factors and use of specialist surgical techniques such as hindfoot nails (HFN) / tibiotalarcalcaneal (TCC) nails and enhanced open reduction and internal fixation (ORIF).

PATIENTS AND METHODS

A UK-wide collaborative study was performed of adult distal AO43/AO44 fractures, associated with 1 or more of the patient factors listed above. Primary outcomes included patient demographics, comorbidities, surgical technique and implants. Secondary outcomes included surgical complications and early post-operative weight bearing instructions. Statistical analysis was performed to assess patient and fracture characteristics on outcome, including propensity matching.

RESULTS

One-thousand three hundred and sixty patients, with at least one of the above complex factors, from 56 centres were included with a mean age of 53.1 years. 90.2% (1227) patients underwent primary fixation which included 78.9% (1073) standard open reduction internal fixations (ORIF), 3.25% (43) extended ORIF and 8.1% (111) primary HFN / TCC. Overall wound complications and thromboembolic events were similar in the hindfoot nail group and the ORIF group (11.7% vs 10.7%). Wound complications were greater in diabetic patients versus non-diabetic patients independent of fixation method (15.8% vs 9.0%). After propensity matching for comorbidities and fracture type, overall complications were lower in the hindfoot nail (11.8%) and extended ORIF groups (16.7%), than the standard ORIF group (18.6%).

CONCLUSION

Only a minority of complex ankle fractures are treated with specialised techniques (HFN/TCC or extended ORIF). Though more commonly used in older and frail patients their perceived advantages are often negated by a reluctance to bear weight early. These techniques demonstrated a better complication profile to standard ORIF but hindfoot nail with joint preparation for fusion was associated with more complications than hindfoot nail for fixation.

Management of High-Risk Ankle Fractures

Successful outcomes in the surgical treatment of the fractured ankle require methods that respect the soft tissue envelope and establish a stable mortise for functional rehabilitation. Ankle fractures in patients with osteopenia and in diabetic patients with deranged bone remodeling constitute high-risk injuries that may result in catastrophic complications. These patients present unique care challenges and should not be approached in the same manner as their healthy counterparts. We present the principles of treatment in high-risk ankle fractures, operative treatment philosophy illustrating techniques frequently used at our institution, and a review of current literature.

Ankle fractures malreduction rate and its causes in two Brazilian tertiary training hospitals

INTRODUCTION

Ankle fractures are one of the most frequent injuries managed by any trauma surgeon. Literature has shown that adequate reduction is of utmost importance to achieve satisfactory functional outcomes. However, malreduction rates remain high worldwide. The objective of the present study is to evaluate the quality of ankle fracture reduction in two major trauma centers in a large Brazilian city and to analyze the factors associated with malreduction METHODS: Epidemiologic data of 382 patients (189 men; 193 women) aged between 7 and 87 years who underwent osteosynthesis of the ankle in two trauma centers in a large Brazilian city. Electronic clinical records, preoperative and immediate postoperative radiographs in anteroposterior (AP), lateral and mortise views were evaluated. Pettrone's criteria were used to evaluate the quality of ankle fractures reduction. All radiographs were independently evaluated by two foot and ankle senior surgeons RESULTS: Overall, malreduction rate was 22.2%. Forty-seven (55.2%) fractures classified as malreduced had medial malleolar displacement The results showed three factors that significantly affected the quality of reduction (p<0.05), patients over 60 years, open fractures and fracture-dislocations. Patients aged over 60 years were twice more likely to have poor reduction of ankle fractures than younger ones. The risk of poor fracture reduction among those individuals with open fractures is 2.15 times greater than among patients with closed injuries. Fracture-dislocation imposed a 2.7 higher risk for malreduction DISCUSSION: We found a malreduction rate below most series previously published. Further results agree with the literature. Elderly people aged over 60 years, fracture dislocations and open fractures are associated with worse results, influencing the quality of the reduction, clinical outcomes, and the development of post-traumatic arthrosis CONCLUSION: Ankle fractures malreduction are associated with higher age, open fractures, and fracture-dislocations.

Risk factors for fracture-related infection after ankle fracture surgery

INTRODUCTION

Ankle fracture surgery comes with a risk of fracture-related infection (FRI). Identifying risk factors are important in preoperative planning, in management of patients, and for information to the individual patient about their risk of complications. In addition, modifiable factors can be addressed prior to surgery. The aim of the current paper was to identify risk factors for FRI in patients operated for ankle fractures.

METHODS

A cohort of 1004 patients surgically treated for ankle fractures at Haukeland University Hospital in the period of 2015-2019 was studied retrospectively. Patient charts and radiographs were assessed for the diagnosis of FRI. Binary logistic regression was used in analyses of risk factors. Regression coefficients were used to calculate the probability for FRI based on the patients' age and presence of one or more risk factors.

RESULTS

FRI was confirmed in 87 (9%) of 1004 patients. Higher age at operation (p < .001), congestive heart failure (CHF), p = 0.006), peripheral artery disease (PAD, p = 0.001), and current smoking (p = .006) were identified as risk factors for FRI. PAD and CHF were the risk factors displaying the strongest association with FRI with an adjusted odds ratio of 4.2 (95% CI 1.8-10.1) and 4.7 (95% CI 1.6-14.1) respectively.

CONCLUSION

The prevalence of FRI was 9% after surgical treatment of ankle fractures. The combination of risk factors found in this study demonstrate the need for a thorough, multidisciplinary, and careful approach when faced with an elderly or frail patient with an ankle fracture. The results of this study help the treating surgeons to inform their patients of the risk of FRI prior to ankle fracture surgery.

Effects of surgical treatment modalities on postoperative cognitive function and delirium in elderly patients with extremely unstable hip fractures

BACKGROUND

As the perioperative risk of elderly patients with extremely unstable hip fractures (EUHFs) is relatively high and therapeutic effect is not satisfactory, new thera-peutic strategies need to be proposed urgently to improve the efficacy and clinical outcomes of such patients.

AIM

To determine the influence of two surgical treatment modalities on postoperative cognitive function (CF) and delirium in elderly patients with EUHFs.

METHODS

A total of 60 elderly patients consecutively diagnosed with EUHF between September 2020 and January 2022 in the Chongqing University Three Gorges Hospital were included. Of them, 30 patients received conventional treatment (control group; general consultation + fracture type-guided internal fixation), and the other 30 received novel treatment (research group; perioperative multidisciplinary treatment diagnosis and treatment + individualized surgical plan + risk prediction). Information on hip function [Harris hip score (HHS)], perioperative risk of orthopedic surgery [Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM)], CF [Montreal cognitive assessment scale (MoCA)], postoperative delirium [mini-cognitive (Mini-Cog)], adverse events (AEs; internal fixation failure, infection, nonunion, malunion, and postoperative delirium), and clinical indicators [operation time (OT), postoperative hospital length of stay (HLOS), ambulation time, and intraoperative blood loss (IBL)] were collected from both groups for comparative analyses.

RESULTS

The HHS scores were similar between both groups. The POSSUM score at 6 mo after surgery was significantly lower in the research group compared with the control group, and MoCA and Mini-Cog scores were statistically higher. In addition, the overall postoperative complication rate was significantly lower in the research than in the control group, including reduced OT, postoperative HLOS, ambulation time, and IBL.

CONCLUSION

The new treatment modality has more clinical advantages over the conventional treatment, such as less IBL, faster functional recovery, more effectively optimized perioperative quality control, improved postoperative CF, mitigated postoperative delirium, and reduced operation-related AEs.

Use of a Hindfoot Nail Without Separate Subtalar and Tibiotalar Joint Preparation to Treat Geriatric Ankle and Distal Tibia Fractures: A Case Series

Introduction

Ankle fractures in geriatric patients can be devastating injuries, as they limit an individual's mobility, autonomy, and quality of life. This study examines the functional outcomes and complications related to hindfoot nails (HFN) in geriatric patients who have suffered an ankle malleolar or distal tibia fracture.

Materials and Methods

This is a single-surgeon case-series of patients who underwent HFN for acute fixation or delayed reconstruction after an ankle or distal tibia fracture. Demographic information, comorbidities, baseline functional status, AO/OTA classification, surgical indications, need for external fixation, total operative time, length of stay (LOS), ambulation at discharge, and discharge disposition were recorded. Primary outcomes included 30-day complications, ambulation at follow-up, and time to fracture union and fusion.

Results

There were 22 patients, with average age 80.8 years. Mean LOS was 7.0 days, and 68.2% were discharged to subacute rehabilitation. Within 30 days, 1 patient developed a deep vein thrombosis and bilateral pulmonary emboli, and 2 experienced wound dehiscence requiring antibiotics. At 6-weeks, 1 patient sustained a fall with periprosthetic fracture requiring HFN revision, and another developed cellulitis necessitating hardware removal. Fracture healing was seen in 72.7% at 19.4 weeks, while radiographic fusion occurred in 18.2% at 43.0 weeks. 72.7% were ambulating with an assistive device at discharge, and 100.0% at 12-weeks post-operatively or last follow-up. Upon final examination, all patients were ambulating without pain.

Discussion

HFNs provide a reliable alternative to traditional open reduction internal fixation and have the ability to improve quality of life for geriatric patients through a faster return to weight-bearing. Additionally, radiographic fusion rates show that patients have favorable functional outcomes even without formal arthrodesis.

Conclusion

HFN is beneficial for elderly patients with low functional demand and complex medical comorbidities, as it allows for early mobility after sustaining an ankle or distal tibia fracture.

Use of Distal Tibial Cortical Bone Thickness and FRAX Score for Further Treatment Planning in Patients with Trimalleolar Ankle Fractures

Trimalleolar ankle fractures show a bimodal age distribution, affecting younger men and older women. Postmenopausal women often exhibit low bone mineral density, which contributes to a higher prevalence of osteoporotic-related fractures. The primary goal of this study was to analyse the association of patient characteristics with the cortical bone thickness of the distal tibia (CBTT) in trimalleolar ankle fractures.

METHODS

A total of 193 patients with a trimalleolar ankle fracture treated between 2011 and 2020 were included. Patient registries were reviewed regarding demographics, mechanism, and type of injury. The CBTT was assessed in radiographs and CT images. The FRAX score was calculated to estimate the probability for an osteoporotic fracture. A multivariable regression model was calculated to identify independent variables affecting the cortical bone thickness of the distal tibia.

RESULTS

Patients older than 55 years were 4.22 (95% CI: 2.12; 8.38) times more likely to be female. In the multivariable regression analysis, female sex (β -0.508, 95% CI: -0.739; -0.278, p < 0.001) and a higher age (β -0.009, 95% CI: -0.149; -0.003, p = 0.002) were independent variables associated with a lower CBTT. Patients with a CBTT < 3.5 mm had a higher 10-year probability for a major osteoporotic fracture (12% vs. 7.75%; p = 0.001).

CONCLUSIONS

The assessment of the peripheral bone quality in routine computed tomography demonstrated that higher age and female sex are significantly associated with reduced cortical bone thickness of the distal tibia. Patients with a lower CBTT showed a higher probability for a subsequent osteoporotic fracture. In female patients with reduced distal tibial bone quality and associated risk factors, an osteoporosis assessment should be evaluated.

Three-dimensional morphological study of type B lateral malleolar fractures with special reference to the end-tip location of proximal apexes

Objective: We aimed to describe the morphological characteristics of Danis-Weber type B lateral malleolar fractures, with special attention given to the end-tip locations of fracture apexes, and to construct a 3D (three-dimensional) fracture line map. Methods: A total of 114 surgically treated cases of type B lateral malleolar fractures were retrospectively reviewed. The baseline data were collected, and computed tomography data were reconstructed in a 3D model. We measured the morphological characteristics and the end-tip location of the fracture apex on the 3D model. All the fracture lines were superimposed on a template fibula to generate a 3D fracture line map. Results: Among these 114 cases, 21 were isolated lateral malleolar fractures, 29 were bimalleolar fractures, and 64 were trimalleolar fractures. All the type B lateral malleolar fractures demonstrated a spiral or oblique fracture line. As measured from the distal tibial articular line, the fracture started at -6.22 ± 4.62 mm anteriorly and terminated at 27.23 ± 12.32 mm posteriorly, and the average fracture height was 33.45 ± 11.89 mm. The fracture line inclination angle was 56.85° ± 9.58°, and the total fracture spiral angle was 269.81° ± 37.09°, with fracture spikes of 156.20° ± 24.04°. The proximal end-tip location of the fracture apex was classified into four zones in the circumferential cortex: zone I (lateral ridge) in seven cases (6.1%), zone II (posterolateral surface) in 65 cases (57%), zone III (posterior ridge) in 39 cases (34.2%), and zone IV (medial surface) in three cases (2.6%). Altogether, 43% (49 cases) of fracture apexes were not distributed on the posterolateral surface of the fibula, as 34.2% (39 cases) were located on the posterior ridge (zone III). The aforementioned morphological parameters in fractures with zone III, sharp spikes, and further broken spikes were greater than those in zone II, blunt spikes, and fractures without further broken spikes. The 3D fracture map suggested that the fracture lines with the zone-III apex were steeper and longer than those with the zone-II apex. Conclusion: Nearly half of type B lateral malleolar fractures had their proximal end-tip of apexes not on the posterolateral surface, which may impair the mechanical application of antiglide plates. A steeper fracture line and longer fracture spike indicate a more posteromedial distribution of the fracture end-tip apex.

Early weight bearing in elderly patients with ankle fractures reduces care needs and maintains independence

BACKGROUND

Ankle fractures in the elderly are increasingly prevalent and are associated with significant morbidity and loss of independence.

METHOD

Patients over the age of 70 suffering ankle fracture were identified using ICD-9-CM patient coding. Fracture stability was assessed using patient records and radiographic evidence. Management strategy, length of inpatient stay, time non-weight bearing, pre-admission residence, discharge destination and discharge care needs were studied.

RESULTS

169 patients with a mean age 80.3 years were studied. Management strategy was shown to have a significant effect on a patient's care requirements (p = 0.012) and ability to return to their primary residence (p = 0.014). Management via an intramedullary rod was associated with the lowest rates of increased care needs (29.7%) and the highest rate of returning home on discharge (88.9%).

CONCLUSIONS

Early weight bearing had a significant effect on a patient's ability to maintain independent living and were more likely to return to their own home.

Can Locked Fibula Nail Replace Plate Fixation for Treatment of Acute Ankle Fracture? A Systematic Review and Meta-Analysis

The standard surgical treatment for unstable ankle fractures involves open reduction and internal fixation (ORIF) with plates. However, ORIF has been associated with several complications, such as soft tissue irritation, wound infection, and nerve injury. Previous studies have shown that closed reduction and internal fixation with locked intramedullary nails (LIMNs) yields satisfactory efficacy in the treatment of ankle fractures and is associated with low complication rates. Therefore, a systematic review and meta-analysis of randomized controlled trials is imperative to provide evidence on whether or not LIMN fixation is comparable to or superior than traditional ORIF. We conducted a comprehensive literature search in the PubMed, Cochrane Library and EMBASE databases. A total of 4 randomized controlled trials involving 359 participants who suffered ankle fractures were included in this systematic review and meta-analysis. The results showed that the LIMN fixation group was statistically significant in terms of functional outcomes at the 3-month follow-up and wound-related complications. There was no statistical advantage for patients in the LIMN fixation group in terms of nonwound-related complications, total complications, or mid-term follow-up functional outcomes. There was no statistical difference between the LIMN and ORIF groups regarding operation time and quality of reduction. We believe LIMN fixation is a viable option for the treatment of unstable ankle fractures in both young and elderly individuals.

A retrospective assessment of the clinical efficacy of different internal fixation methods in the treatment of distal fibula fractures in the elderly

An ankle fracture is a fracture of the distal tibia or fibula that forms the ankle joint, usually associated with ligament and soft tissue injury, and is a common type of lower limb fracture and one of the most common types of fracture in the elderly. Although ankle fractures are one of the most common injuries seen by orthopedic trauma surgeons, there is no uniform protocol for the diagnosis and treatment of ankle fractures in the elderly, and there are many controversial indications for surgery. The aim of this study is to assess the clinical efficacy of different internal fixation methods in the treatment of distal fibular fractures in the elderly, in an effort to improve the rational selection and application of clinical acts. A retrospective analysis was performed on 68 cases of patients who suffered an ankle fracture and were treated with different internal fixation methods according to the fracture types and individual differences in distal fibula fractures. The postoperative therapeutic effect assessment was performed in terms of clinical examination, imaging evaluation, and AOFAS ankle-hind foot function scoring. There was no unhealed bone, ankle instability and loose/fractured internal fixation. Fracture healing time was 2.7 to 4.0 months (average 3.2 months). AOFAS score was 88.3 ± 6.2, of which, 34 excellent cases, 30 good cases, and 4 fair cases. Ankle activity dorsiflexion 6º~18º, average 15º; plantar flexion 26º~47º, average 37º. A good clinical efficacy could be achieved from the most appropriate individualized internal fixation for distal fibula fractures of elderly patients.

Ankle tibiotalocalcaneal nailing in elderly ankle fractures as an alternative to open reduction internal fixation: technique and literature review

The use of tibiotalocalcaneal nails for unstable ankle fractures in low demand elderly patients has been introduced as an alternative to open reduction internal fixation to allow early weight-bearing and to decrease soft tissue complications and mechanical failures. This paper describes the technique of hindfoot nailing and reviews the current literature. Overall, it is a minimally invasive and expeditious procedure that provides stable fixation to withstand immediate ambulation of the frail elderly patient. Future high-quality randomized controlled trials will determine if complications and outcomes compare favorably to open reduction and internal fixation.

When is the optimum time for the initiation of early rehabilitative exercise on the postoperative functional recovery of peri-ankle fractures? A network meta-analysis

Objective

The purpose of this study was to explore the safe and most effective initiation time for the functional recovery of patients with peri-ankle fractures after surgery.

Method

We searched electronic databases, including the Cochrane Library, Embase, PubMed and the reference lists of relevant articles published from inception to October 30, 2021. Two researchers independently performed literature screening and data extraction and evaluated the quality of the included literature using the Newcastle–Ottawa Scale. Network meta-analysis, including consistency testing, publication bias, and graphical plotting, was performed using Stata (v16.0).

Results

A total of 25 articles involving 1756 patients were included in this study. The results of the meta-analysis showed that functional exercise within 2 days after surgery may result in lower VAS scores compared to other techniques (P < 0.05). Functional exercise within 12 months may lead to higher AOFAS scores than that of other techniques (P < 0.05). The total postoperative complication rate, including deep vein thrombosis, showed no statistically significant differences between any two interventions (P > 0.05). The results of the surface under the cumulative ranking (SUCRA) showed that functional exercise within two days postoperatively may have the lowest VAS scores (SUCRA = 82.8%), functional exercise within 1 week postoperatively may have the lowest deep vein thrombosis rate (SUCRA = 66.8%), functional exercise within 10 days postoperatively may have the fewest total postoperative complication rate (SUCRA = 73.3%) and functional exercise within 12 months postoperatively may contribute to the highest AOFAS scores (SUCRA = 85.5%).

Conclusion

The results of this study suggest that initiation of rehabilitation within two days after surgery may be the best time to reduce postoperative pain; rehabilitation interventions within 10 days after surgery may be the optimal time for reducing the total postoperative complication rate, including deep vein thrombosis; and continued functional exercise within 12 months after surgery may steadily and ideally improve the function of the ankle joint.

Treatment of bimalleolar fractures in elderly

Geriatrics continues to evolve as a specialty by adapting itself to increasingly older patients. Musculoskeletal injuries are common in these patients, who can maintain their physical capacities and autonomy for a long time, but whose bone solidness is frequently reduced by osteoporosis. Falls increase with age and because of certain medical conditions. Trauma in the geriatric population involves specific risks; thus, the treatment must be adapted not only to the fracture, but to the local conditions and the patient. Ankle injuries are particularly frequent in general traumatology but even more in geriatric traumatology. They can lead to complete loss of autonomy if the treatment is delayed and/or not adapted to the local conditions or the patient. The functional prognosis is brought into play, along with the patient's life due to loss of autonomy and general complications occurring in patients who are bed-ridden. The treatment of bimalleolar ankle fractures in older adults requires rigorous analysis at all points, which starts by evaluating the cutaneous status and viability of the soft tissues upon admission. The benefit-risk balance of the various treatment options will be assessed with the main goal being that patients recover their autonomy. This article will review this topic by answering 7 questions: 1) What are the distinctive features of elderly? Dependence on others, comorbidities, bone and soft tissue fragility are the main ones, explaining these high-risk situations and frequent complications. 2) When should a bimalleolar ankle fracture be treated surgically? The surgery must be done early, preferably within 8hours of the injury occurring, once the comorbidities have been controlled. The local conditions (skin and soft tissue damage) must be evaluated carefully as they determine the treatment. Errors are not allowed in these patients, who are often fragile and in precarious health. Definitive fixation is preferred if the skin status allows it, but one must keep temporary external fixation in mind as an option. 3) Is there still a role for conservative treatment of displaced fractures? This will produce good results when it is well done; however, the indications are rare and must be selected carefully. The main risks are secondary displacement and skin lesions inside the cast, which are sources of infection. 4) Is fixation with anatomical locking plates an advance? This is definitely an advance for these fragility fractures, which are often comminuted, as it allows return to weight bearing in certain conditions. However, the implantation rules must be followed exactly, and it is preferable to use thinner plates. 5) Does transplantar Steinmann pin fixation still have a role? It has few indications, limited to salvage situations (catastrophic local conditions, very poor general condition). External tibiocalcaneal fixation, alone or in combination, is a better option. 6) Is immediate transarticular fixation with a retrograde or antegrade locked nail a reasonable option? Fixation can be done by retrograde nailing or antegrade nailing. It is proposed to patients who are not very autonomous with a poor cutaneous status and/or severe osteoporosis. It is preferable to transplantar nailing. 7) Is immediate protected weight bearing, with or without fixation, possible? This can be considered on a case-by-case basis depending on the extent of the trauma, patient compliance and treatment carried out. LEVEL OF EVIDENCE: V, Expert opinion.

The Quality of Life, Patient Satisfaction and Rehabilitation in Patients With a Low Energy Fracture-Part III of an Observational Study

Introduction

Due to the aging population the incidence of Low Energy Fractures (LEF) increases. LEF have high mortality and morbidity rates and often cause elderly to lose independence. Patient-reported outcomes, such as Quality of Life (QoL) and patient satisfaction (PS) are needed to evaluate treatment, estimate cost-benefit analyses, and to improve clinical decision-making and patient-centered care.

Objective

The primary goal was to evaluate QoL and PS in patients with LEF, and to compare QoL scores to the community dwelling population. Second, we observed the amount and type of physiotherapy (PT) sessions the patients conducted.

Methods

A single-center cohort study was conducted in Switzerland. Patients between 50 and 85 years, who were treated in the hospital for LEF, were followed 1 year after initial fracture. Data on QoL were obtained through the Euroqol-5-Dimension questionnaire-3-Level (EQ-5D-3L) and the EQ VAS (visual analog scale). PS was measured by a VAS on satisfaction with treatment outcome. Data on PT sessions, mobility and use of analgesics were collected by telephone interviews and written surveys. Results were compared between the different fracture locations and subgroup analyses were performed for age categories.

Results

411 patients were included for analysis. The median scores of the EQ-5D-3L index-VAS and PS were 0.90 (0.75-1.0), 90 (71.3-95) and 100 (90-100). Significant differences in all scores were found between fracture location (P < .05), with hip fracture patients and patients with a malleolar fracture scoring lowest in all measures. QoL index in hip fracture patients was 0.76 (0.70-1.00), QoL VAS 80 (70-90), and PS 95 (80-100). Median amount of PT sessions in all patients was 18 (9-27) and a significant difference was found between fracture locations. Patients with a fracture of the humerus received the highest amount of PT sessions 27 (18-36), hip fracture patients had a median of 18 (9-27) sessions.

Conclusion

At follow-up, QoL throughout all patients with a LEF was comparable to a normal population. Remarkably, though hip fracture patients seem to suffer from a clinically relevant loss of QoL, they received fewer PT sessions and performed fewer long-lasting home training than patients with a humerus fracture. Intensive, progressive rehabilitation with a high frequency of supervised training is recommended after hip fracture. The low frequency of PT sessions found in this study is unsatisfying. In hip fracture patients and in patients with a malleolar fracture, especially when aged over 75 years, more efforts are required to improve rehabilitation and subsequently QoL.

Standards of open lower limb fracture care in the United Kingdom

Open fractures of the lower limb remain a potentially devastating group of injuries that are challenging to manage. The primary aims of treatment are to optimise limb function and avoid serious complications such as infection and non-union, which are costly for both the patient and healthcare system. The management of these fractures has evolved significantly, and this is evident following the creation of national open fracture guidelines and a formal trauma system. These have served to standardise care for these injuries in the United Kingdom. The aim of this review is to update our colleagues on the current standard of lower limb open fracture care in the United Kingdom, and the impact this has had on patient outcomes.

Fracture blisters: pathophysiology and management

Open fractures are considered an orthopaedic emergency due to the severe soft tissue disruption that might potentially lead to devastating complications. On the other hand, closed fractures, and especially those resulting from high-energy mechanisms, are also often accompanied by severe soft tissue trauma. Soft tissue envelope compromise can have a detrimental effect on the final outcome of the patients. Fracture blisters in particular, develop as a sign of significant local tissue trauma and appear in a time period between 6 to 72 hours post-injury. They can delay the definitive fracture treatment for a considerable amount of time and at the same time they also increase the risk for post-operative wound complications. Awareness of fracture blisters pathophysiology and their management options are crucial for orthopaedic surgeons, in order to achieve a favorable clinical outcome. In the herein study we present a concise synopsis of the pathophysiology pathways and management options of fracture blisters.
