The functional outcome of severe, open tibial fractures managed with early fixation and flap coverage

Bipedicled DIEAP flaps for reconstruction of limb soft tissue defects in male patients

BACKGROUND

Extensive soft tissue deficiencies involving the limbs can be difficult to reconstruct and may require more than one microsurgical flap transfer to cover the defect. This can be particularly challenging in male patients, where the sacrifice of a donor muscle could result in considerable comorbidity. This paper describes the use of the bipedicled deep inferior epigastric artery perforator (DIEAP) flap to perform a one-stage reconstruction of extensive soft tissue defects in male patients.

METHODS

By using preoperative multidetector computed tomographic (MDCT) angiography, the dominant perforators of the abdominal wall were identified and the bipedicled DIEAP flap was used for a one-stage reconstruction of complicated tissue loss in 12 male patients. In seven of these flaps, a microsurgical anastomosis between the two epigastric pedicles of the DIEAP flap was carried out. The feasibility of the procedure, clinical outcome, and possible associated comorbidities were evaluated.

RESULTS

Successful large tissue reconstructions were performed using all four traditional zones of the DIEAP flap, with dimensions of flaps ranging from 20 × 8 to 50 × 17 cm. Venous congestion was seen to develop in two flaps, one of which was salvaged by performing an additional venous anastomosis, but the other flap failed to survive. Apart from this, complications were minimal.

CONCLUSIONS

Soft tissue coverage of extensive wounds in male patients without sacrificing muscle flaps can be challenging. This extended utilization of the entire DIEAP flap has helped us to address this issue.

Early Conversion of External Fixation to Interlocked Nailing in Open Fractures of Both Bone Leg Assisted with Vacuum Closure (VAC) - Final Outcome

INTRODUCTION

Management of compound grade III fractures of both bone leg includes external stabilization for long period, followed by various soft tissue coverage procedures. Primary interlocking of tibia had been also done with variable results. External fixation for long time without any bone loss often leads to infected nonunion, loss of reduction, pin tract infection and failure of fixation, primary interlocking in compound grade III fractures had shown high medullary infection rate. We managed all cases of compound grade III A/B fractures with primary external fixation, simultaneous wound management using vacuum assisted closure (VAC) followed by early conversion to interlocking within 2 weeks of fixator application.

AIM

To determine the effectiveness of vacuum assisted closure (VAC) for the early conversion of external fixator to definitive interlocking in open fractures of the both bone leg.

MATERIALS AND METHODS

In current study we selected 84 cases of compound grade IIIA/B diaphyseal fractures of both bone leg during period of May 2010 to September 2013. We managed these cases by immediate debridement and application of external fixation followed by repeated debridement, application of vacuum assisted closure (VAC) and conversion to interlocking within two weeks.

RESULTS

Out of 84 cases union was achieved in 80(95%) of cases with definitive tibial interlocking. Excellent to good result were obtained in 77(91.8%) of cases and fair to poor result seen in rest of 7(8.2%) of cases according to modified Ketenjian's criteria. 5 out of these 7 poor result group cases were from Compound Grade III B group to start with. Deep infection rate in our series were 7% i.e. total 6 cases and 4 out of these were from compound Grade III B group to start with.

CONCLUSION

Vacuum assisted closure (VAC) give a good help for rapid closure of the wound and help in early conversion to definitive intramedullary nailing. Reamed nail could well be used in compound grade IIIA/B fractures without increasing the risk of infection. It gives better stability to fracture site and lessen the risk of implant failure.

Outcome of Type 3 Open Tibial Diaphyseal Fractures Managed with a Limb Reconstruction System: Analysis of a 49-Patient Cohort

OBJECTIVE

To evaluate functional and radiological results following treatment with the single-plane external fixator limb reconstruction system (LRS) for open tibial diaphyseal fractures resulting from high-energy trauma.

SUBJECTS AND METHODS

From a total of 62 patients who were operated on between 2011 and 2014 for open tibial diaphyseal fractures resulting from high-energy trauma, 50 tibias from 49 patients (males: 32, females: 17) were classified as type 3 according to the Gustilo-Anderson open fracture classification, and definitive treatment was applied with the LRS. The patients ranged in age from 20 to 36 years. Time to union, time of external fixator usage, complications and functional results according to the Johner-Wruhs criteria were recorded.

RESULTS

The mean follow-up period was 23 ± 12 months (range: 11-44). Of the 50 tibias, full union was achieved with the LRS in 48 (96%). No shortness or deformity was observed in any patient. Knee and ankle range of movement were measured as full in all patients at the final follow-up examination after removal of the LRS. The mean time to union was 20.4 ± 4 weeks (range: 16-24). The mean time of external fixator use was 20 weeks (range: 16-24 weeks).

CONCLUSION

In this study, for the definitive treatment of open tibia diaphyseal fractures, the LRS was an optimal and safe choice that offered single-stage surgery.

Is delayed reconstruction using the latissimus dorsi free flap a worthy option in the management of open IIIB tibial fractures?

Early reconstruction of severe open fractures, performed within 7 days of the injury, has a better outcome than closure after 7 days. However, the uncertain demarcation of damaged tissue often results in delayed reconstruction. In this article, we report our surgical outcomes of delayed reconstruction using latissimus dorsi free flap with internal fixation. Twenty-three patients with Gustilo type IIIB open tibial fractures Between March 2009 and May 2012 were included in this study. There were 16 cases of distal 1/3 fracture of the tibia, 4 of midshaft fracture, 1 of proximal 1/3 fracture, and 2 of segmental fracture. Serial debridement with application of negative pressure wound therapy (NPWT) was performed before the final operation. All patients underwent internal fixation of the bone and reconstruction of soft tissue defect using latissimus dorsi free flap. The number of serial debridements, excluding those performed during emergency and finial operation, ranged from 1 to 5 (mean 2.69) times. Mean time from injury to final operation was 10.65 (range, 7-22) days. All flaps survived without complications. Three cases (13%) were infected, and three cases required further bone graft surgery to facilitate bone union (13%). Bone union was achieved after a mean 6.3 (range, 3-12) months. Mean follow-up period was 16.34 (range, 12-26) months. During follow-up, all patients were able to ambulate without use of an aid. In cases of severe open fracture, treatment should emphasize soft tissue coverage rather than rushing to achieve definitive fixation in the setting of poor surrounding tissues. When delayed reconstruction is inevitable, radical debridement is performed first, then NPWT is used as bridging therapy, and free flap could be considered for definite soft tissues coverage. © 2015 Wiley Periodicals, Inc.

Grade 3 open tibial shaft fractures treated with a circular frame, functional outcome and systematic review of literature

We report on the surgical and functional outcome of 22 patients with Grade 3 open tibial fractures treated with circular frame. All cases united and there were no re-fractures or amputations. All patients were assessed at a minimum of 1-year post frame removal. Assessment included clinical examination, IOWA ankle and knee scores, Olerud and Molander ankle score and EuroQol EQ-5D. Clinical scores were either good or excellent in over half of the patients in all knee and ankle scores. There was a significant positive correlation between functional outcomes and the EQ-5D score. The EQ-5D mean health state visual analogue score was comparable to the general UK population despite patients scoring less than the average UK population in three of the five domains. 36% reported some difficulties in walking and 41% had problems with pain. 14% had difficulties with self-care and 46% had difficulties with their usual activities. 14% had problems with anxiety or depression. Systematic review of the literature suggests, in the management of open tibial fractures, circular frames provide equivalent or superior surgical outcomes in comparison with other techniques. Our study finds the application of a circular frame also results in a good functional outcome in the majority of cases.

Early versus late flap coverage for open tibial fractures

PURPOSE

To compare early versus late flap coverage for open tibial fractures.

METHODS

Medical records of 83 men and 6 women (mean age, 38 years) who underwent fixation for open tibial fractures (Gustilo grades IIIB and IIIC) followed by flap coverage within (n=30) or after (n=59) 72 hours were reviewed. All fractures were treated within 24 hours. Outcome measures included bone union, infection, flap failure, the need for secondary procedures to achieve union, and eventual amputation. The early and late flap coverage groups were compared.

RESULTS

Early flap coverage was associated with shorter length of hospitalisation (31.4 vs. 55.8 days, p<0.01), lower deep infection rates (23% vs. 54%, p<0.01), and smaller number of surgical procedures (6.4 vs. 9.2, p=0.01). The 2 groups did not differ significantly in terms of the time to bone union, flap failure, amputation, and the need of secondary procedures to facilitate bone union.

CONCLUSION

In severe open tibial fractures, early soft-tissue coverage (within 72 hours) was associated with more favourable outcomes in terms of length of hospitalisation and infection.

The ortho-plastic approach to soft tissue management in trauma

Fractures with associated soft tissue injuries, or those termed 'open,' are not uncommon. There has been much discussion regarding there management, with the guidance from the combined British Orthopaedic Association and British Association and Aesthetic Surgeons teams widely accepted as the gold level of therapy. We aim to discuss the current evidence about the initial management of this group of injuries, taking a journey from arrival in the accident and emergency department through to the point of definitive closure. Other modes of therapy are also reviewed.

A staged surgical treatment outcome of type 3 open tibial fractures

Aim. In these case series which are about type 3 open tibial fractures formed with three different high energy trauma etiologies in different parts of tibia. We aimed to assess our three-stage treatment approach and discuss final results of our elective surgery management with three different fixation methods. Patients and Methods. We assessed 19 patients with type 3 open tibial fractures between 2009 and 2012. Our treatment protocol consisted of three stages. Early intervention in operating room, which including vascular repairs or soft tissue closure, was done if necessary. Definitive surgery was performed using internal or external fixation in the first 15 days. Patients were followed up for at least one year. Last conditions of all our cases were evaluated according to modified Johner and Wruhs criteria. Results. Nine cases were type 3A, seven cases were type 3B, and three cases were type 3C in terms of fracture typing. All patients were followed up for at least one year and mean follow up time was 15 months. In terms of functional and clinical outcome, six cases were evaluated as excellent, eight cases as good, two cases as fair, and three cases as poor. Discussion. Staged treatment option in type 3 open tibial fractures seems to be a good method in reducing complication and achieving the best result. We think that definitive staged treatment protocol including internal fixation with plating or intramedullary nailing (IMN) of the fractures is a reliable method, especially to avoid complications as a result of external fixator and to provide patient rapport.

Clinical course, complication rate and outcome of segmental resection and distraction osteogenesis after chronic tibial osteitis

INTRODUCTION

Radical segmental resection and subsequent distraction osteogenesis are considered the gold standard in the treatment of chronic tibial osteitis. We investigated the clinical course of treatment, particularly with respect to patients' quality of life, and the complication rate associated with this technique.

METHODS

In this prospective case series, 25 patients (22 men, 3 women, average age: 46 years) with chronic post-traumatic tibial osteitis were managed operatively from 2006 to 2009. Standardised treatment included bacterial eradication by segmental resection, bone transport using Ilizarov apparatus, and docking manoeuvre. The follow-up rates during bacterial eradication, bone transport, post docking, and complete osseous consolidation were 100% while follow-up two years after completed consolidation was 76%. The main outcome measurements consisted of the quality of life (Medical Outcomes Study 36-Item Short Form Health Survey (SF-36 score)) and the virtual analogue scale (VAS) of pain during the five stages of therapy. Additionally, all complications and difficulties were documented.

RESULTS

The average defect size was 5.3 cm (range: 3-13). The healing index was 57 days per cm transport (range: 18-172). The overall treatment time averaged 93 weeks (range: 38-183). Patients suffered 22 minor and 13 major complications including one amputation. The average complication rate per patient consisted of 0.88 minor and 0.52 major complications. After the period of bone transport, the physical and mental component summary scores increased continuously. After completed consolidation, the average mental summary score was comparable to a normal collective.

CONCLUSIONS

Distraction osteogenesis is challenging for both the patient and the surgeon. The arduous and demanding nature of the clinical course subjects the patient to considerable mental and physical stress. Thankfully, the average physical and mental status of health continues to improve during the clinical course of treatment. The 2-year success rate of the distraction osteogenesis in an infected tibia is 96%.

Soft-tissue reconstruction of open fractures of the lower limb: muscle versus fasciocutaneous flaps

Early vascularized soft-tissue closure has long been recognized to be essential in achieving eventual infection-free union. The question of whether muscle or fasciocutaneous tissue is superior in terms of promoting fracture healing remains unresolved. In this article, the authors review the experimental and clinical evidence for the different tissue types and advocate that the biological role of flaps should be included as a key consideration during flap selection.

A qualitative approach to recovery after open tibial fracture: the road to a novel, patient-derived recovery scale

AIM

The aim of this study was to describe how patients perceive their recovery following open tibial fractures using a qualitative approach.

PATIENTS AND METHODS

Following the appropriate ethical approval, adult patients with a diagnosis of open tibial fracture were recruited after completion of their surgical treatment and discharge from Morriston Hospital, a centre with orthoplastic surgical care. A purposive sampling method was employed to ensure that a range of injuries as well as clinical outcomes were included. All patients took part in an in-depth semi-structured interview, exploring aspects of their injury, treatment, rehabilitation and psychosocial and financial situations. Interviews were completed with two interviewers present and were recorded for verbatim transcription. Interview transcripts were analysed to identify items important to patients during their recovery.

RESULTS

Nine patients with a mean injury to interview interval of 2.3 years were interviewed. A total of 538 items were identified and subsequently mapped onto 18 categories: pain; mobility; flexibility; temperature (effects on symptoms); fear; appearance; sleep; diet/weight; employment; social; finance; impact on others; self-care; recovery (patient perceptions of recovery); frustration; goal setting (by patients and health-care providers); and adaptation (both physical and mental).

CONCLUSION

There is a wide range of factors that our cohort found important during their recovery from open tibial fracture. Despite being considered as 'healed' by the medical staff, patients did not report a corresponding full recovery and return to pre-injury normality. The categories identified will enable the development of a patient-reported recovery scale to be used in lower-limb trauma.

Reimplantation of an extruded osteoarticular segment of the distal tibia in a 14-year-old girl. Case report and review of the literature

This case report describes the reimplantation of a 15-cm osteoarticular segment of the distal tibia in a 14-year-old girl who was hit by a truck. The bone fragment was debrided and reimplanted on the day of injury. A free flap was performed within 1 week. Bony union was achieved without complication. At 5-year follow-up, the patient is able to ambulate for several hours at a time without an assistive device, although arthritis of the ankle joint is present. She scores 43.8 on the physical component of the 36-Item Short Form Health Survey and 49.0 on the mental component. The patient states that she is very pleased with her outcome. This seems to be the first description of an osteoarticular segment reimplantation of a long bone in the orthopaedic literature.

A meta-analysis of amputation versus limb salvage in mangled lower limb injuries--the patient perspective

This meta-analysis evaluates the quality of life in post-traumatic amputees in comparison with limb salvage. Studies included in this meta-analysis had a minimum of 24 months of follow-up and used a validated quality-of-life outcome assessment scale (Short Form-36 or Sickness Impact Profile) for physical and psychological outcomes. Two reviewers performed the search and data extraction independent of each other. A total of 214 studies were identified; 11 fulfilled the inclusion criteria; thus, 1138 patients were available for meta-analysis (769 amputees and 369 cases of reconstruction). The meta-analysis demonstrated that lower limb reconstruction is more acceptable psychologically to patients with severe lower limb trauma compared with amputation, even though the physical outcome for both management pathways was more or less the same.

Segmental transports for posttraumatic lower extremity bone defects: are femoral bone transports safer than tibial?

BACKGROUND

The long-term outcomes following femoral and tibial segment transports are not well documented. Purpose of the study is to compare the complication rates and life quality scores of femoral and tibial transports in order to find what are the complication rates of femoral and tibial monorail bone transports and if they are different?

METHODS

We retrospectively analyzed the medical records of 8 femoral and 14 tibial consecutive segment transports performed with the monorail technique between 2001 and 2008 in our institution. Mean follow-up was 5.1 ± 2.1 years with a minimum follow-up of 2 years. Aetiology of the defects was posttraumatic in all cases. Four femoral (50%) and nine tibial (64%) fractures were open. The Short Form-36 (SF-36) health survey was used to compare the life quality after femoral and tibial bone transports. The Mann-Whiney U test, Fisher exact test, and the Student's two tailed t-test were used for statistical analysis. P ≤ 0.05 was considered to be statistically significant.

RESULTS

The tibial transport was associated with higher rates of severe complications and additional procedures (1.5 ± 0.9 vs. 3.4 ± 2.7, p = 0.048). Three patients of the tibial group were amputated because of recurrent infections and one developed a complete regenerate insufficiency that was treated with partial diaphyseal tibial replacement. Contrary to that none of patients of the femoral group developed a complete regenerate insufficiency or was amputated.

CONCLUSIONS

Tibial bone transports have a higher rate of complete and incomplete regenerate insufficiency and can more often end in an amputation. The authors suggest systematic weekly controls of the CRP value and of the callus formation in patients with posttraumatic tibia bone transports. Further comparative studies comparing the results of bone transports with and without intramedullary implants are necessary.

Fixation and reconstruction of severe tibial shaft fractures with vascularized fibular grafting

INTRODUCTION

Based on the considerable experience for management of combined bone and composite soft-tissue defects in the limbs by free vascularized fibula or osteocutaneous fibular flap grafting, the authors present the effective alternative for management of the severe comminuted tibial shaft fractures in one-stage reconstructive technique.

METHOD

Twenty-six patients were male and 12 were female, and their mean age was 32 years (range 15-57 years). Ten tibial shaft fractures were closed and 28 were open. Based on the AO classification, there were 12 group C1 fractures and 24 group C3 fractures according to the fracture pattern and degree of comminution.

RESULTS

With the exception of eight cases that were delayed for 3-5 days for primary treatment in another hospital, 30 cases were treated on an emergency basis within an average of 12 h since the initial injury (range 6-22). Normal healing occurred in 31 fractures with a mean healing time of 21 weeks (range 18-24 weeks). Delayed union in 7 with a mean of 32 weeks (range 28-41 weeks), and there were no nonunion and infections. The vascularized fibula allows for fast bone fusion. In this context, the grafted fibula segment appeared to be a valuable reconstructive tool that offered good fracture stabilization and vascularised bone graft.

CONCLUSION

The attached fibular flap can also provide a large piece of mobile skin to cover the soft-tissue defect in grade III open-tibial fractures. It demonstrates that this early free vascularized fibula graft is a useful and effective option for treating the severe comminuted tibial shaft fractures.

One-stage treatment and reconstruction of Gustilo Type III open tibial shaft fractures with a vascularized fibular osteoseptocutaneous flap graft

OBJECTIVES

This study evaluated the usefulness of a single-stage, free-fibular vascularized osteoseptocutaneous flap transfer for Type III open tibial shaft fractures with segmental bone loss for the reconstruction of combined bone and soft tissue defects.

DESIGN

Nonrandomized retrospective study.

SETTING

University Level I trauma center.

PATIENTS/PARTICIPANTS

All Gustilo Type III open tibial shaft fractures with segmental bone loss that were treated at one institution between 2000 and 2007 were identified from a trauma registry. The study group consisted of 28 patients with Type III open tibial fractures: 27 were Gustilo-Anderson Type IIIB and one was Grade IIIC. The cause of tibial injury included eight industrial accidents, seven motor vehicle accidents, five crushing injuries caused by heavy objects, five falls from a height, and three motorcycle crashes. The lengths of the preoperative segmental tibial bone loss ranged from 9 to 17 cm and the size of the associated soft tissue defects ranged from 8 × 6 cm to 15 × 7 cm.

INTERVENTION

The free fibular vascularized osteoseptocutaneous flap was used to graft and reconstruct combined bone and soft tissue defects. The radical wound débridement, soft tissue and bone revision, fracture stabilization, and early soft tissue coverage were achieved by this technique in a one-stage procedure. The average duration from injury to one-stage reconstruction was 15.8 hours (range, 5.3 hours to 6.5 days).

MAIN OUTCOME MEASUREMENT

Radiographic and functional evaluation of the lower extremity.

RESULTS

All free fibular osteoseptocutaneous flaps survived completely. The average time to overall union for the entire group was 32 weeks after surgery (range, 26-41 weeks). None of the patients in this series had a nonunion. Acceptable radiographic alignment, defined as 5° of angulation in any plane, was obtained in 22 patients (78.6%). Malunion affected six (21.4%) fractures. According to the lower extremity functional assessment, excellent and good results were achieved for 82.1% (23 of 28), fair results were seen in 14.3 % (four of 28), and a poor result occurred in one case (3.5%).

CONCLUSION

The free fibular vascularized osteoseptocutaneous flap grafting is an effective alternative in management of Type III open tibial fractures using a one-stage procedure. The grafted fibula offers good fracture stabilization plus a vascularized bone graft, and the fibular flap can also provide a large piece of mobile skin to cover the soft tissue defect in Type III open tibial fractures. The free osteoseptocutaneous flap also serves as a visible monitor of the adequacy of the circulation of the grafted fibula.

Fix and flap in the era of vacuum suction devices: What do we know in terms of evidence based medicine?

INTRODUCTION

The concept of immediate or early fixation and soft tissue coverage of open fractures is frequently referred to as 'fix and flap,' and negative pressure wound therapy (NPWT) has had a major impact in this area. This article aims to review concepts and evidence relevant to the use of NPWT in open fractures.

REVIEW OF OPEN FRACTURE MANAGEMENT

Muscle flaps in open fractures do well in part because they improve blood supply to the underlying fracture. Outcomes of muscle flaps are best when done acutely, before bacterial colonisation. The colonised subacute wound is managed with 'open-wound techniques' until it becomes a chronic localised wound, when flap coverage is again indicated. NPWT provides a useful adjunct in this process as the zone of injury is determined. VACUUM-ASSISTED CLOSURE: REVIEW OF BASIC AND CLINICAL SCIENCE LITERATURE: Proposed mechanisms of action of NPWT include: increased blood flow, decreased oedema, cytokine release induced by mechanical stretch and increased lactate and oxygen tension in the tissue with induction of collagen transcription and angiogenesis. VACUUM-ASSISTED CLOSURE IN OPEN FRACTURES: NPWT to open fractures caused early appearance of healthy granulation tissue, a reduction in wound area and allowed simpler soft tissue procedures for wound closure. NPWT also improved clinical survival of muscle flaps despite occluded flap venous outflow.

SUMMARY

The aim in open fractures is to stabilize the fracture and achieve soft tissue coverage before infection develops. NPWT, applied as a temporizing dressing, simplifies soft tissue coverage on the 'reconstructive ladder.' The only Level-I data on that topic showed a significant decrease in infections. However, NPWT does not allow delay in soft tissue coverage. NPWT increases the 'take rate' of skin grafts, skin substitutes and composite skin grafts and allows quicker graft incorporation.

Comparison of 39 post-traumatic tibia bone transports performed with and without the use of an intramedullary rod: the long-term outcomes

Bone transport can be performed with an external fixator alone or with the monorail technique which entails the combination of a fixator and an intramedullary nail. The purpose of this study was to compare the complication rates and long-term outcomes of these methods. Two groups of patients, the external fixator (n = 21) and the monorail group (n = 18), were compared. The average follow-up period was 7.9 ± 5.6 years and the mean defect length 8.3 ± 3.1 cm. Healing was achieved in 19 (90%) and 13 (72%) of the fixator and monorail patients, respectively. Six patients underwent amputations because of persistent infections (two in the fixator and four in the monorail group). The rate of deformities was significantly higher in the fixator group (p = 0.049). No statistically significant difference was found when comparing categories of the SF-36 test or the ability to work or do sports. The main advantages of the monorail method are reduction of the external fixation time and the lower rate of deformities. However, the authors recommend segmental transport with external fixator in patients with chronic infections.

National data of 6409 Swedish inpatients with femoral shaft fractures: stable incidence between 1998 and 2004

INTRODUCTION

Femoral shaft fractures are commonly thought to be primarily associated with high-energy trauma in young persons. Only limited attention has been given to low-energy violence as a cause of these fractures among the elderly. National epidemiological data on characteristics of patients with femoral shaft fractures are lacking, so the purpose of this study was to analyse the incidence, admissions, causes of fracture and operations for these fractures on a nationwide basis in Sweden during 1998-2004.

PATIENTS AND METHODS

Data on all femoral shaft fractures were extracted from the Swedish National Hospital Discharge Registry. Sex- and age-specific fracture incidence, hospital admissions, mechanisms of injury and surgical procedures were analysed using descriptive analysis, linear-regression analysis and other methods as appropriate.

RESULTS

Over a period of 7 years, 6409 patients with femoral shaft fractures were identified, corresponding to an annual incidence of 10 per 100,000 person-years. Men had a younger median age (27 years, IQR 12-68) than women (79 years, IQR 62-86) (p<0.001). Females (54%) generated more admissions than males (46%). The incident rate ratio between men and women was 0.9 (p<0.001). Most hospital admissions were generated among females by the 80-89 years age-group and among males <10 years of age. 2% of the fractures were open fractures. The total number of hospital admissions was stable during 1998-2004. The two major mechanisms of injury were falls on the same level (50%) and transport accidents (17%). A significant number of fractures occurred among elderly patients after low-energy trauma. Osteosynthesis with femoral nail (54%) was the preferred operation, followed by osteosynthesis with plate and screws (16%), skeletal traction (14%) and external fixation (6%).

DISCUSSION

This nationwide study on femoral shaft fractures provides an update on incidence, admissions, external causes and surgical procedures. This information assists health-care providers in planning hospital beds, surgical interventions and risk preventions. Moreover, these data can be used for power calculations for further clinical studies.

Long-term quality of life in trauma patients following the full spectrum of tibial injury (fasciotomy, closed fracture, grade IIIB/IIIC open fracture and amputation)

AIMS AND OBJECTIVES

To measure long-term functional outcome and health-related quality of life following tibial fracture in association with the full spectrum of soft tissue injury.

METHODS

One hundred and thirty patients with different types of tibial injury were selected from our trauma database. This included 33 patients with compartment syndrome (no underlying fracture), 30 with closed diaphyseal tibial fractures, 45 with grade IIIB/IIIC open fractures and 22 requiring below knee amputation. Mean time to final follow-up was 37.4 months. The EQ-5D (EuroQol) questionnaire was used to assess these patients at this point. Patients had been treated according to standard unit protocols. Open fractures were jointly managed under the care of local plastic and orthopaedic surgeons using a policy of obtaining early soft tissue cover.

RESULTS

Patients with reconstructed IIIB fractures reported problems with pain and carrying out their normal activities more frequently than amputees whilst still reporting problems with mobility just as frequently. Anxiety and depression were more common in the patients with open fractures and amputees as were problems with self-care, though the latter were unusual overall. Stepwise logistic regression revealed that tibial injury type was significantly predictive of all measured outcomes except self-care (p<0.0001). Age, ISS, sex and time to follow-up were not significant predictors of response.

CONCLUSIONS

These results show that patients with these injuries still report long-term problems with their health-related quality of life, though to varying degrees. This information is useful when determining the treatment options for these patients and it is important that it is shared with the patient prior to surgery where possible.

A systematic review of outcomes and complications of reconstruction and amputation for type IIIB and IIIC fractures of the tibia

BACKGROUND

The question of whether to recommend amputation or salvage after type IIIB and IIIC tibial fractures remains unanswered. The purpose of this study was to conduct a systematic review to derive evidence-based recommendations concerning primary amputation versus limb salvage for type IIIB and IIIC open tibial fractures.

METHODS

Articles from Medline, Cinahl, and Embase that met predetermined criteria were included. Outcomes of interest included length of hospital stay, complications, rehabilitation time, quality of life, limb function, pain, and return to work data. Pooling of statistical data was performed when possible.

RESULTS

The authors reviewed 1947 articles, and 28 observational studies were included. Length of hospital stay was 56.9 days for salvage patients and 63.7 days for amputees. The most common complications after salvage attempt were osteomyelitis (17.9 percent), nonunion (15.5 percent), secondary amputation (7.3 percent), and flap failure (5.8 percent). Rehabilitation time for salvaged patients was reported as time to union (10.2 months) and time to full weight-bearing (8.1 months). Pain, quality of life, and limb function outcomes were assessed differently among studies and could not be combined. The proportion of patients who returned to work was 63.5 percent for salvage patients and 73 percent for amputees.

CONCLUSIONS

The current literature offers no evidence to support superior outcomes of either limb salvage or primary amputation for type IIIB and IIIC tibial fractures. When outcomes are similar between two treatment strategies, economic analysis that incorporates cost and preference (utility) may define an optimal treatment strategy to guide physicians and patients.

Comparison of the healing of open tibial fractures covered with either muscle or fasciocutaneous tissue in a murine model

The objective of this study was to compare the effects of soft tissue coverage by either muscle or fasciocutaneous tissue on the healing of open tibial fractures in a murine model. An open tibial fracture, stripped of periosteum with intramedullary fixation, was created in mice. Experimental groups were devised to allow exclusive comparison of either muscle alone or skin plus fascia in direct contact with healing bone. To exclusively assess the relative efficacy of muscle and fasciocutaneous tissue to promote healing of a fracture stripped of periosteum, a piece of sterile inert material (polytetrafluoroethylene) was positioned anteriorly, excluding skin and fascia (muscle group) or posteriorly, excluding muscle (fasciocutaneous group). Skeletal repair was assessed histologically and quantified by histomorphometry; quantitative peripheral computed tomography (pQCT) and mechanical testing using a four-point bending technique. This standardized, reproducible model allowed characterization of the morphology of open fracture healing. At 28 days postfracture, there was faster healing in the experimental muscle coverage group compared to skin and fascia alone. Furthermore, there was almost 50% more cortical bone content and a threefold stronger union beneath muscle compared to fasciocutaneous tissue (p < 0.05 by one-way ANOVA). Exclusive comparison of muscle and fasciocutaneous tissue in our novel murine model demonstrates that muscle is superior for the coverage of open tibial fractures for both the rate and quality of fracture healing.

Decreasing incidence of tibial shaft fractures between 1998 and 2004: information based on 10,627 Swedish inpatients

BACKGROUND AND PURPOSE

There is a lack of national epidemiological data on the characteristics of patients with tibial shaft fractures. We therefore analyzed data on Swedish patients with tibial shaft fractures in this nationwide population study based on data from 1998 through 2004.

METHODS

Data on all patients with tibial shaft fractures were extracted from the Swedish National Hospital Discharge Register.

RESULTS

We identified 10,627 hospital admissions for tibial shaft fractures, corresponding to an annual incidence rate of 17 per 100,000 person-years (pyr). The number of hospital admissions decreased by 12% during the period 1998-2004, mostly from a reduction in male incidence. The median (SD) age at admission was 28 (22) years for men and 51 (26) years for women. The two major mechanisms of injury were falls on the same level (48%) and transport accidents (21%). Surgical procedures were dominated by osteosynthesis with nail (48%), followed by closed reduction and plaster cast (27%), and external fixation (12%). 12% of all tibial shaft fractures were classified as open, corresponding to an incidence rate of 2.3 per 100,000 pyr, which declined during 1998-2004.

INTERPRETATION

This nationwide study of tibial shaft fractures shows a falling off of fracture incidence, a finding that can be used to advantage by healthcare providers.

Outcomes of isolated tibial shaft fractures treated at level 1 trauma centres

BACKGROUND

Although most tibial shaft fractures are expected to heal within 24 weeks, the long-term effects of these injuries on patients in terms of self-reported health status, disability, and pain are largely unknown.

OBJECTIVES

To investigate the clinical and patient-reported outcomes of patients with isolated tibial shaft fractures treated at the two level 1 adult trauma centres in Victoria, Australia.

METHODS

Sixty patients with isolated tibial shaft fractures treated at the Royal Melbourne Hospital and the Alfred Hospital between August 2003 and August 2004 were identified via the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR). Patient-reported outcomes were prospectively measured 1 year post-injury using the 12-Item Short-Form Health Survey (SF-12) (also administered at baseline); the Work subscale of the Sickness Impact Profile; and a Numerical Rating Scale for pain. A priori defined clinical outcomes were also determined by retrospectively reviewing hospital medical records and X-rays.

RESULTS

Full weight-bearing status was achieved after a median inter quartile range (IQR) time of 14.0 (12.5-20.0) weeks, and the median (IQR) time to radiological union was 35.8 (23.3-51.6) weeks. Sixty percent of patients completed the SF-12 at both baseline and 12 months post-injury. Although there were no clear changes in mental health scores (median change=+1.0; IQR=-3.5 to 4.0; p=0.52), physical health scores were significantly reduced (median change=-3.0; IQR=-19.5 to 0.3; p=0.003). Additionally, 47% of patients reported work-related disability and 40% experienced persistent pain 1 year post-injury.

CONCLUSIONS

These results indicate that long-term physical disability remains a problem for many patients following tibial shaft fracture, and they should be considered when providing prognostic information to patients. Further research is required to identify the specific health problems experienced as well as the factors contributing to disability in order to inform post-fracture rehabilitation planning.

Management of open fractures of the tibial shaft in multiple trauma

BACKGROUND

The work presents the assessment of the results of treatment of open tibial shaft fractures in polytrauma patients.

MATERIALS AND METHODS

The study group comprised 28 patients who underwent surgical treatment of open fractures of the tibial shaft with locked intramedullary nailing. The mean age of the patients was 43 years (range from 19 to 64 years). The criterion for including the patients in the study was concomitant multiple trauma. For the assessment of open tibial fractures, Gustilo classification was used. The most common concomitant multiple trauma included craniocerebral injuries, which were diagnosed in 12 patients. In 14 patients, the surgery was performed within 24 h after the injury. In 14 patients, the surgery was delayed and was performed 8-10 days after the trauma.

RESULTS

The assessment of the results at 12 months after the surgery included the following features: time span between the trauma and the surgery and complications in the form of osteomyelitis and delayed union. The efficacy of gait, muscular atrophy, edema of the operated limb and possible disturbances of its axis were also taken under consideration. In patients operated emergently within 24 h after the injury, infected nonunion was observed in three (10.8%) males. These patients had grade III open fractures of the tibial shaft according to Gustilo classification. No infectious complications were observed in patients who underwent a delayed operation.

CONCLUSION

Evaluation of patients with open fractures of the tibial shaft in multiple trauma showed that delayed intramedullary nailing performed 8-10 days after the trauma, resulted in good outcome and avoided development of delayed union and infected nonunion. This approach gives time for stabilization of general condition of the patient and identification of pathogens from wound culture.

Open grade III "floating ankle" injuries: a report of eight cases with review of literature

INTRODUCTION

"Floating ankle" injuries result from high-energy trauma and are usually associated with extensive soft tissue damage. Such rare and complex injuries in the acute phase pose therapeutic dilemma to the treating surgeon. When salvage instead of amputation is preferred, a variety of treatment options are available ranging from open reduction along with minimal internal fixation to external fixation. In this retrospective case series study we report eight patients with open "floating ankle" injuries who had been treated with external fixation with or without internal fixation.

MATERIALS AND METHODS

Eight consecutive patients (7M: 1F) with mean age of 28 years (range 18-35 years) were treated. All had Grade III open fractures of the distal tibia with foot fractures and various degrees of soft tissue injuries. ISS and MESS were used to assess injury severity. Immediate radical wound debridement; skeletal stabilization and early soft tissue coverage were done by combined trauma and plastic surgical services followed by standard post-operative rehabilitation. All the patients were assessed with SF-36 questionnaire at mean follow-up of 2.5 years (range 2-4 years).

RESULTS

Three patients were treated primarily with Ilizarov ring fixators, one had hybrid fixation and the other four had Hoffman frames. Four patients needed further surgeries. One patient developed metatarsal osteomyelitis, which was debrided and treated with antibiotics. The SF-36 results were compared with age matched UK norms for men and women in all categories. Only two patients returned to their previous employment. Six suffered varying degrees of disability out of which one underwent amputation.

CONCLUSIONS

External fixation with or without internal fixation is an option when salvaging rare injuries like open grade III "floating ankle" injuries. Salvaged patients do suffer a cocktail of crippling disease characterized by psycho-socio-economic and physical disability and result in increased hospital costs. We recommend more prospective studies with long-term follow-up of such complex injuries to identify the indications for salvage and also the criteria for a successful salvage.

The effect of the timing of antibiotics and surgical treatment on infection rates in open long-bone fractures: a 9-year prospective study from a district general hospital

AIMS

To determine whether a delay of greater than 6h from injury to initial surgical debridement and the timing of antibiotic administration affect infection rates in open long-bone fractures.

METHODS

We studied 248 consecutive open long-bone fractures in 237 patients over a 9-year period. The patients were followed until clinical or radiological union occurred or until a secondary procedure for non-union or infection was performed.

RESULTS

Surgical debridement was performed within 6h of injury in 62% of cases and after 6h in 38% of cases. Infection rates were 7.8% and 9.6%, respectively, and the difference was not statistically significant (p=0.6438). The timing of antibiotic administration was not significantly related to the infection rate.

CONCLUSION

Whilst open long-bone fractures should be treated expeditiously, we suggest that adherence to a 6h window has not been shown to affect infection rates nor has the timing of antibiotic administration during the acute phase.

Immediate interlocking nailing versus external fixation followed by delayed interlocking nailing for Gustilo type IIIB open tibial fractures

PURPOSE

To compare immediate interlocking nailing with external fixation followed by delayed interlocking nailing, for Gustilo type IIIB open tibial fractures.

METHODS

23 patients with Gustilo IIIB open tibial fractures were treated with either immediate unreamed interlocking nailing (n=9) or external fixation followed by delayed unreamed interlocking nailing (n=14). Patient age, sex ratio, fracture site, fracture type, and severity were similar in both groups. The time to union, deep infection rate, and nonunion rate in the 2 groups were compared.

RESULTS

In the immediate and delayed nailing groups, respective mean times to union were 21 (standard deviation [SD], 14) months and 14 (SD, 8) months; nonunion rates were 44% (4/9) and 36% (5/14), and deep infection rates were 22% (2/9) and 7% (1/14). All corresponding differences were not statistically significant.

CONCLUSION

Prospective, randomised, multicentre studies are needed to assess whether there are significant differences between the 2 treatment methods.

Open fractures of the tibia treated by immediate intramedullary tibial nail insertion without reaming: a prospective study

OBJECTIVE

Does immediate tibial nail insertion without reaming as part of protocol-driven management provide a safe and effective treatment for open tibia fractures?

STUDY DESIGN

Prospective cohort.

SETTING

Level 1 trauma center.

PATIENTS

A consecutive series of 161 patients with Gustilo grade I-IIIb open tibia fractures.

INTERVENTION

Emergent incision and debridement of the wound with immediate tibial nail insertion without reaming, repeat incision and debridement, and soft-tissue coverage within 14 days.

MAIN OUTCOME MEASUREMENTS

Time to union, number of secondary procedures performed to obtain union, implant failures, and the type and incidence of complications.

RESULTS

One hundred and forty-three fractures were followed to union. Follow up averaged 2.2 years (0.6-5.5 years). Seventy-six fractures united in less than 6 months, 35 took between 6 and 9 months, and 32 took longer than 9 months. Twenty-five additional procedures were needed to obtain union in 16 of the delayed unions (12 nail exchanges, 4 bone grafts, 9 dynamizations). Complications included 3 patients with cellulitis, 1 superficial infection, 4 deep infections (1 grade I, 2 grade II, 1 grade IIIb), 3 loose screws, 2 broken screws, 5 malunions greater than 5 degrees, and 30 patients with decreased ankle motion when compared with the uninjured side. Not counting the ankle loss of motion, 18 complications occurred in 143 fractures (13%). Twenty-nine patients (20%) had complaints of minor knee pain and 30 (21%) had occasional fracture site pain after activity despite clinical and radiographic evidence of union. Eleven patients (8%) considered themselves completely disabled. Five patients were not treated by the standard protocol and are not included in the previously listed statistics; 3 were grade IIIB that did not have adequate coverage by 14 days, and 2 were grade II injuries that did not have a second debridement. Four of these 5 patients developed a complication.

CONCLUSIONS

Protocol-driven management emphasizing meticulous soft-tissue management and the use of immediate tibial nailing without reaming appears to be safe and effective in the treatment of open tibia fractures. The deep infection rate for the patients who were treated by protocol was 3% and the implant failure rate was lower than has been previously reported, most likely attributable to attempts to obtain cortical contact and avoid fracture gaps. Overall satisfaction was good, but approximately 41% of the patients had complaints of knee or fracture site pain or both well after union.

Primary shortening with secondary limb lengthening for Gustilo IIIB open tibial fractures: a report of six cases

BACKGROUND

The treatment of type IIIB open tibial fractures remains a challenge for orthopedic surgeons, particularly with respect to the soft-tissue and subsequent bony reconstruction. The primary shortening and limb lengthening (PSLL) simplifies wound closure for severe open injuries without requiring microsurgical procedures as a main advantage. This method is thought to be also useful for type IIIB patients with polytrauma and other life-threatening injuries because it helps to control both wound sepsis and their general state. In the present study, we attempted to assess the problems, long-term functional outcome, and quality of life (QOL) of patients who were treated by PSLL for Gustilo type IIIB open tibial fractures in our facility.

METHODS

Six patients with type IIIB open tibial fractures treated with PSLL were retrospectively reviewed. The mean shortening length was 7.4 cm (range, 4.5-10.3 cm). The mean percent shortening of the entire bone was 18.7% (range, 12.3-29.7%). Limb lengthening started at a mean interval of 10.3 months (range, 3-18 months) after the original injury. The mean healing index was 56.5 days/cm (range, 31.3-86.7 days/cm). The complications, functional outcome, and quality of life were evaluated for all cases.

RESULTS

One superficial infection at the initial corticotomy, one deep infection around the shortening site, one refracture at the healed docking site, several wire breaks in external frames in two cases, and two severe equinovarus deformities occurred as complications of these procedures. Regarding functional outcome, three patients showed good outcome, two showed fair outcome, and one showed poor outcome. The percent shortening of the entire bone in the two fair cases were more than 25%. The median scale of physical health summary, mental health summary, and total general health summary in Short Form-36 (QOL) were lower than the standard scale in age-matched individuals.

CONCLUSION

This PSLL treatment was thought to be a useful option for severe open fracture of the tibia, which had bony defect in more than 4.5 cm in length after serial debridement, although several complications occurred in this regimen. However, it is difficult to achieve an excellent function and QOL using these techniques. In addition, it is difficult for patients who underwent limb lengthening after shortening more than 25% of the total length of bone to gain good function.

Is staged external fixation a valuable strategy for war injuries to the limbs?

High-energy weapons or blast injuries usually result in substantial tissue damage and are serious medical and public health problems. We report our experience with staged external fixation for war injuries to the extremities. Forty-seven patients with 64 high-energy limb fractures caused by war weapons were retrospectively reviewed. The fractures were associated with severe soft tissue damage. There were 14 Gustilo-Anderson Type IIIA fractures, 40 Type IIIB fractures, and 10 Type IIIC fractures. Soft tissue débridement followed by axial realignment of the fractured bones with immediate skeletal stabilization using the AO/ASIF unilateral tubular external fixator was performed on the day of admission. The primary tubular fixators were exchanged 5 to 7 days later for Ilizarov frames. Delayed primary closure, skin grafts, or flaps were used for soft tissue coverage. The mean followup was 40 months, and the Ilizarov/hybrid external fixator was the definitive treatment in all patients. Bone union was achieved at an average of 8 months in 58 (90.6%) fractures. Three patients had nonunions and one patient required an amputation. Two patients were lost to followup. Staged external fixation is a valuable strategy for treatment of war injuries to the extremities.

Management of severe open tibial fractures: the need for combined orthopaedic and plastic surgical treatment in specialist centres

Although it is widely accepted that grade IIIB open tibial fractures require combined specialised orthopaedic and plastic surgery, the majority of patients in the UK initially present to local hospitals without access to specialised trauma facilities. The aim of this study was to compare the outcome of patients presenting directly to a specialist centre (primary group) with that of patients initially managed at local centres (tertiary group). We reviewed 73 consecutive grade IIIB open tibial shaft fractures with a mean follow-up of 14 months (8 to 48). There were 26 fractures in the primary and 47 in the tertiary group. The initial skeletal fixation required revision in 22 (47%) of the tertiary patients. Although there was no statistically-significant relationship between flap timing and flap failure, all the failures (6 of 63; 9.5%) occurred in the tertiary group. The overall mean time to union of 28 weeks was not influenced by the type of skeletal fixation. Deep infection occurred in 8.5% of patients, but there were no persistently infected fractures. The infection rate was not increased in those patients debrided more than six hours after injury. The limb salvage rate was 93%. The mean limb functional score was 74% of that of the normal limb. At review, 67% of patients had returned to employment, with a further 10% considering a return after rehabilitation. The times to union, infection rates and Enneking limb reconstruction scores were not statistically different between the primary and tertiary groups. The increased complications and revision surgery encountered in the tertiary group suggest that severe open tibial fractures should be referred directly to specialist centres for simultaneous combined management by orthopaedic and plastic surgeons.

Functional outcome and quality of life of Gustilo IIIB open tibial fractures requiring free tissue transfers: a report of eight cases

Eight patients with type IIIB open tibial fractures requiring free tissue transfers were retrospectively reviewed. The functional outcome was evaluated by using a scoring system developed by Puno et al. (Microsurgery 17:167-173, 1996). Short Form 36 (SF-36) was used as a measurement of individuals' quality-of-life (QOL) scores. The average total score of all cases was 77.6. An excellent or good functional outcome was achieved in 37.5% (3/8). Six patients were evaluated by SF-36. The average physical health summary (T-PH) score was 47.9, the average mental health summary (T-MH) score was 53.5, and the average total general health summary (T-GH) score was 50.7. The mean T-MH score was significantly higher than the mean T-PH score (P < 0.05). Treated cases showed an acceptable QOL, considering the results of the T-GH. The mental QOL was higher than the physical QOL. In severe open tibial fractures, it is difficult to obtain a good or excellent functional outcome, even with reconstruction using free tissue transfers.
