Managing soft tissues in severe lower limb trauma in an ageing population

Nationwide study on open tibial fractures in the Netherlands: Incidence, demographics and level of hospital care

OBJECTIVES

Open tibial fractures are relatively common injuries following traffic accidents. The vulnerability of the soft tissues surrounding the tibia increases the susceptibility to complications, including infection and nonunion. To minimize complications, a multidisciplinary, timely approach is crucial. To date, the Dutch incidence and level of hospital treatment remain unknown due to a lack of condition-specific nationwide registries. This study aimed to estimate the incidence and management of open tibial fractures in the Netherlands, providing essential information for public health policymaking and guideline development.

METHODS

The 2018 and 2019 Dutch National Hospital Care Basic Registration data, provided by the Dutch Hospital Data Foundation, were utilized to identify all patients admitted to Dutch hospitals with tibial fractures. Incidence rates, patient demographics, primary diagnoses, fracture classification, level of hospital, and length of hospital stays were analyzed using descriptive statistics.

RESULTS

1,079 ICD-10 codes for closed and open tibial fractures were identified in patients that were admitted to a Dutch hospital. Thirty-four percent were classified as open tibial fractures, accounting for an estimated incidence rate of 1.1 per 100,000 person-years (95 % CI 0.97-1.12). When categorized by age, the calculated incidence rate was higher in males for all age categories up until the age of 70. Notably, the overall highest incidence rate was found for females aged 90 and above (6.6 per 100,000 person-years). Open tibial fractures were predominantly treated in general or top clinical hospitals (comprising 69 % of open all tibia fractures). Notably, the minority (31 %) presented at university medical centers, all Level-1 trauma centers, equipped with orthoplastic teams.

CONCLUSION

This is the first study to report the nationwide incidence rate of open tibial fractures in the Netherlands; 34 % of tibial fractures were registered as open. Notably, a limited proportion of open tibial fractures underwent treatment within Level-1 trauma centers. Consequently, in the majority of cases, the implementation of an orthoplastic team approach was unattainable. This study underscores the need for more comprehensive data collection to assess and improve the current treatment landscape.

Tibiotalocalcaneal nail and primary closure for the management of open ankle fractures in the elderly patient; results from a major trauma centre

INTRODUCTION

Open ankle fractures in elderly patients are challenging injuries to manage. The aim of this study was to assess the outcome of elderly patients with open ankle fractures treated with a tibiotalocalcaneal nail and primary wound closure.

METHODS

We identified all open ankle fractures in patients over 65 referred to our major trauma centre managed with a tibiotalocalcaneal nail and primary wound closure over 10 years. We recorded patient demographics, comorbidities, injury mechanism, length of stay, operation, weightbearing status, re-operations, infections and mortality.

RESULTS

We included 34 patients with an average age of 87 (73-99). We found 56 % of patients' mobility status declined post-operatively and 21 % of patients were discharged directly home. Four patients required further unplanned surgery including two deep infections requiring amputation. We had a 6 % three month mortality rate.

CONCLUSION

Use of a tibiotalocalcaneal nail with primary wound closure offers a reasonable treatment option for open fractures of the ankle in the elderly patient.

"Fix and flap" for an open fracture of the tibia in a 97-year-old patient: A case report of early internal fixation and free flap reconstruction

INTRODUCTION

The incidence of open fractures in super-old patients has increased. "Fix and flap" procedures using early internal fixation and free flap reconstruction in super-old patients are rarely reported.

PRESENTATION OF CASE

A 97-year-old woman presented to our emergency department after a car accident. She was diagnosed with an open fracture of the lower leg, and the open wound could not be closed after debridement. The tibia was fixed using an intramedullary nail on the day of injury, and the open wound was closed using a free latissimus dorsi myocutaneous flap on the sixth day. The flap was engrafted at the 1-year follow-up after the injury, and the patient was able to walk using a cane.

DISCUSSION

To facilitate flap elevation and shorten the operative time, a flap with fewer vascular variants should be selected, and flow-through anastomosis that does not obstruct peripheral blood flow with a high patency rate is preferable. Reconstructive free flap surgery is preferably performed within 1 week of the initial injury to prevent fibrosis or scarring of recipient vessels.

CONCLUSION

The "fix and flap" procedure, composed of early internal fixation and free flap reconstruction, is possible even in super-old patients through careful considerations of flap selection, methods of anastomosis of blood vessels, and timing of surgery. However, it is necessary to determine whether the affected limb can be preserved or amputated, and prolonged treatment must be avoided.

Free flaps for lower limb soft tissue reconstruction - A systematic review of complications in 'Silver Trauma' patients

BACKGROUND

There are 12.5 million people aged 65 years and older living in the UK. The annual incidence of open fracture is 30.7 per 10,000 person-years. In females, 42.9% of all open fractures occur in patients ≥ 65 years.

METHODS AND MATERIALS

Preferred Reporting for Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and the study is registered with PROSPERO (CRD42020209149). The aim was to compare the complication profiles of free fasciocutaneous flaps and free muscular flaps in patients aged over 60 years undergoing lower limb soft tissue reconstruction following an open lower limb fracture. The search strategy based on strict inclusion criteria included PubMed, Embase and Google Scholar.

RESULTS

15 papers were identified, including 46 patients with 10 free fasciocutaneous flaps and 41 free muscle flaps. There were 3 complications in the fasciocutaneous group (30%) and 9 complications in the muscle group (22%). There was a total of 1 secondary procedure in the fasciocutaneous group and 4 in the muscle group.

DISCUSSION

There is insufficient data to provide statistical comparison between free fasciocutaneous versus free muscle flaps for lower limb reconstruction performed in those aged over 60 years. This systematic review highlights evidence for the successful use of free tissue transfer in the older population following an open fracture injury and requiring lower limb reconstruction. There is no evidence to suggest the superiority of one tissue type over the other, with the inference that well vascularised tissue is the most significant factor impacting outcome.

Open lower extremity fractures in the geriatric population

INTRODUCTION

Open fractures in the elderly are distinct compared to younger populations. The purpose of this study is to follow a series of open fractures of the lower extremity in the geriatric population to better prognosticate outcomes.

METHODS

We performed a retrospective chart review of patients over the age of 65 years old who were treated for an open, lower extremity fracture across two level I trauma medical systems. Patients were included if they had documented wound healing problems in the postoperative period, or 6 months of follow-up, or if they had a definitive radiographic outcome. Sixty-four patients were included of an average age of 76.23, of whom 73.4% were female.

RESULTS

The fracture types were midshaft femur in 3, distal femur in 9, patella in 2, proximal tibia in 3, proximal fibula in 1, midshaft tibia in 14, distil tibia in 8, ankle in 23, and talar neck/calcaneus in 1. Forty-two fractures were the result of low energy mechanism and 22 fractures were from high energy mechanism. Fourteen fractures were type 1, 32 were type 2, 11 were type 3A, 6 were type 3B, and 1 was type 3C. At final follow-up, 13 wounds were well healed, 39 wounds were healed following a delay of more than 6 weeks to achieve healing, 3 were infected, 3 had been treated with amputation, 2 had chronic ulceration, 2 with active draining, and 2 had draining sinuses.

DISCUSSION

Open lower extremity fractures are serious injuries with high rates of morbidity. Such risks are even higher in the geriatric population, particularly with regard to wound healing. This study provides important prognostic information in counseling geriatric patient with an open lower extremity fracture, as well as informs treatment in terms of wound surveillance and care in the postoperative period.

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.

Management of Gustilo-Anderson IIIB open tibial fractures in adults-a systematic review

INTRODUCTION

Open tibial fractures are the most common open long bone fracture, despite this, the management of these complex injuries still remains a topic of discussion amongst orthopaedic surgeons.

SOURCES OF DATA

We searched the EMBASE, MEDLINE and Google Scholar and a systematic review of 7500 articles, leaving 23 after exclusion criteria were applied, in order to analyse the management of open tibial fractures.

AREAS OF AGREEMENT AND CONTROVERSY

Infection was noted to be the most significant concern amongst authors, with definitive external fixation having a high rate of superficial pin-site infection and internal fixation having a high deep infection rate.

GROWING POINTS

It is essential to have a combined ortho-plastic approach to the management of these fractures as muscle flaps were the most common form of soft tissue coverage.

AREAS TIMELY FOR DEVELOPING RESEARCH

A national pragmatic trial into the management of open tibial fractures is required looking at fixation methods and soft tissue coverage, with at least a 2-year follow-up in order to ascertain the most appropriate management of these fractures and patient-related outcomes.

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.

A health economic analysis of the management of open lower limb fractures in the elderly

AIM

The aim of this study was to investigate the financial implications of the inpatient management of open lower limb fractures in adults over 65 years old. Further, the study compares the calculated cost to the income received by the hospital for these patients and to the existing body of literature.

METHODS

This study employed direct inpatient costing analysis to estimate the cost of treating the open lower limb fractures incurred by 58 patients over the age of 65 years treated in our centre (Addenbrooke's Hospital, Cambridge University Hospitals NHS Trust) between March 2014 and March 2019.

RESULTS

The median cost of inpatient care calculated in this study was £20,398 per patient, resulting in a financial loss to the hospital of £5113 per patient. When the results were disaggregated by sex, the median cost for an open lower limb fracture in a male patient was £20,886 compared to £19,304 in a female patient. Data were also disaggregated by the site of injury, which produced a median cost for an open femur fracture of £23,949, and £24,549 and £15,362 for open tibia and ankle fractures, respectively.

CONCLUSION

This study provides a valuable estimate of the expense of treating open lower limb fractures in patients over the age of 65 years in a Major Trauma Centre in England. The study highlights the large losses incurred by hospitals in treating these cases, and supports revision of the remuneration structures in the National Health Service to adequately cover their cost.

Gustilo-Anderson type III tibial fractures have poor functional outcomes in patients over 75 years

BACKGROUND

Previous outcome studies in open tibial fractures have commonly assessed young patients and there is a paucity of data regarding outcomes in the elderly. The aim of this study is to assess functional outcomes for patients over 75 years with Gustilo-Anderson Grade III open tibial fractures, including mobility and residential status.

METHODS

Outcomes for all patients over 75 years admitted with grade III open tibial fractures to a UK level 1 trauma centre during a 5-year period (January 2010-May 2015) were analysed. Long-term follow up of surviving patients (median 44 months post injury) was undertaken in February 2016.

RESULTS

Twenty-nine patients (24 female, 5 male - median 85 years) were included. Prior to injury 48% (n = 14) patients were independently mobile and 45% (n = 13) were living at home without care. Two-thirds of injuries were low energy; all patients sustained a grade III open tibial fracture. The 12-month mortality rate was 28% (n = 8) and mortality at long-term follow-up 48% (n = 14). From pre-injury to long-term 8% (n = 1) patients did not change mobility status, 75% (n = 9) reduced by one grade (e.g. independent to walking aid) and 16% (n = 2) by two grades. Fifty eight percent (n = 7) of patients retained residential status, 17% (n = 2) reduced by one grade and 25% (n = 3) by two grades.

CONCLUSION

Grade III open tibial fractures are a significant injury in the elderly associated with poor outcomes with respect to return to mobility and pre-injury residential status. Our results suggest that a greater emphasis on intensive rehabilitation should be considered in this patient group.

Foot salvage using microsurgical free muscle flaps in severely crushed foot with soft tissue defects

OBJECTIVE

Management of complex foot injuries including skin, tendons, vessels, bone, with soft tissue defects is considered as an orthopedic challenge. Microsurgical free muscle flaps provide the best solution in such cases.

PATIENTS AND METHODS

Thirty two consecutive cases of complex ankle and foot injuries were treated by skin grafted muscle free flap in one stage procedure after radical debridement. Twenty four were males and 8 were females. Right foot was affected in 26 and left was involved in 6 patients. The average age was 22 years (range 6-33 years). The most common cause of injury was motor car accident. All cases had complex soft tissue defect with bone exposure. All cases were candidate for amputation. Gracilis muscle transfer was done in 26 cases and latissimus dorsi free flap in 6 cases. The average follow up was 38 months.

RESULTS

All the free muscle flaps survived. The involved bone fracture was united at an average 3 months. No evidence of osteomyelitis was noted. Full weight bearing was restored 3 months post-operatively. All patients were satisfied with the cosmetic appearance and functional capacity of their operated limbs.

CONCLUSION

Skin-grafted free muscle flap as one-stage procedure is a good solution for reconstruction of complex ankle and foot injuries.

Selecting a free flap for soft tissue coverage in lower extremity reconstruction

BACKGROUND

Goals of lower extremity microvascular reconstruction (LEMR) include the restoration of function, prevention of infection, and optimal cosmesis. Indications for LEMR include large defects that are not amenable to pedicled options, a large zone of injury, and large complex defects. The novice microsurgeon should first master a handful of free flaps to develop an armamentarium of options for addressing such defects. The scope of this review is to provide free flap options for LEMR in any of the thirds of the lower leg. After reading this article, the reader will understand variations, advantages, disadvantages, indications, and tips for raising each of these flaps.

METHODS

Six most commonly used free flaps for LEMR are described in this paper, including the anterolateral thigh flap (ALT) and its variations, the radial forearm flap (RFFF), the lateral arm flap (LAF), the gracilis muscle flap, the rectus abdominis flap (RAF) and the latissimus dorsi flap and its variations. Indications, advantages, disadvantages and technique tips are discussed for each flap. Moreover, selection of the recipient vessels, preoperative management along with an algorithm are also provided.

CONCLUSIONS

The ALT flap is a workhorse in covering defects of the leg, foot, and ankle. It's the flap of choice at our institution, especially given the number of traumatic wounds seen as a result of motor vehicles, all-terrain vehicles (ATV), lawnmowers, and gunshot wounds (GSW). At times, the lower extremity zone of injury requires a distant donor site. The RAF can also provide coverage for large soft tissue defects but donor-site morbidity remains its main drawback. The LAF and RFFF provide two pliable options, one that provides pliable soft tissue with minimal donor site morbidity and another that provides a long pedicle. The free gracilis flap is an excellent choice for crossing the ankle joint. Lastly, the free latissimus dorsi is indicated for large defects of the lower extremity independently of the location.

Rectus abdominis free tissue transfer in lower extremity reconstruction: Long term follow up in 58 cases

This study evaluates the long-term results of rectus abdominis free-tissue transfer performed for lower extremity reconstruction.

METHODS

Over a period of 8 years 58 were available for long term follow-up. Indications for reconstruction included acute wounds with soft tissue defects, diabetic foot ulcers, and chronic osteomyelitis.

RESULTS

At a mean follow-up of 18 years, there were no major complications in the soft tissue defect coverage group except for one patient who continued to have recurrent folliculitis over the weight bearing heel area, which was treated by repeated debridement. Among the diabetic patients, two patients had recurrent ulcerations of the forefoot which were detected early and treated conservatively. In the osteomyelitis group, however, there were no recurrences of the foot infection.

CONCLUSIONS

The rectus abdominis free-tissue transfer provided an excellent method of soft tissue reconstruction with a very minimal long-term complication rate, and a very high rate of success in the treatment of diabetic foot ulcers and chronic osteomyelitis.

A comparison between the Major Trauma Centre management of complex open lower limb fractures in children and the elderly

INTRODUCTION

Open lower limb fractures can be devastating with outcomes determined by tissue damage and adherence to strictly defined care pathways. Managing such injuries in paediatric and elderly populations presents logistical and technical challenges to achieve best outcomes. Orthoplastic principles were developed mainly in the young adult population whereas requirements for paediatric and elderly patients need further understanding.

METHODS

A retrospective analysis was performed on two groups of patients at the extremes of age, with type IIIb (severe) open lower limb fractures, presenting to a Major Trauma Centre (MTC) with orthoplastic services over a six-year period - the first group being under 16 years; the second group being over 65. The timelines of combined surgery to both fix the fracture and flap the soft-tissue defect were strictly observed. Each group were followed-up for a minimum of nine months. Data were analysed according to patient demographics, mechanism of trauma, time to wound excision, time to definitive surgery, fixation technique, soft-tissue reconstruction type, deep infection rate, flap survival, bony union, secondary amputation and functional outcome (Enneking score).

RESULTS

33 paediatric patients and 99 elderly patients were identified. Paediatric: The median age was 12 years. All the children were ASA Grade I. Open tibial fractures were most common (76%) followed by ankle fracture dislocation (12%). The majority were high-energy injuries and were commonly managed with external fixators (or frames) and free flap coverage. Median hospital stay was 12 days, and time to union 114 days, with median Enneking scores of 85%. There was one flap failure and no deep infections. Elderly: The median age was 76 years. ASA grades varied and reflected multiple comorbidities. High-energy injuries required free flaps, while more common, low-energy fragility fractures were covered with loco-regional flaps. Internal fixation with intramedullary nails was most commonly used. Median hospital stay was 13 days, and time to union was 150 days, with median Enneking scores of 70%. There was one flap failure, one deep infection, and one delayed amputation.

DISCUSSION

These results reflect both similarities and important differences in managing open fractures in the extremes of age. The specific challenges of each group of patients are discussed, including surgical aspects, but also the importance of orthoplastics infrastructure within the MTC and input from allied professionals to facilitate patient pathways.
