Treatment of compound tibia fracture with microvascular latissimus dorsi flap and the Ilizarov technique: A cross-sectional study of long-term outcomes

Effectiveness of permissive weight bearing in surgically treated trauma patients with peri- and intra-articular fractures of the lower extremities: a prospective comparative multicenter cohort study

PURPOSE

The aim of the present study was to investigate the effectiveness of a novel approach involving permissive weight bearing (PWB) in surgically treated trauma patients with peri- and intra-articular fractures of the lower extremities.

METHODS

Prospective comparative multicenter cohort study in one level 1 trauma center and five level 2 trauma centers. Surgically treated trauma patients with peri- and intra-articular fractures of the lower extremities were included. Permissive weight bearing (PWB) in comparison to restricted weight bearing (RWB) was assessed over a 26-week post-surgery follow-up period. Patients' self-perceived outcome levels regarding activities of daily living (ADL), quality of life (QoL), pain and weight bearing compliance were used.

RESULTS

This study included 106 trauma patients (N = 53 in both the PWB and RWB groups). Significantly better ADL and QoL were found in the PWB group compared to the RWB group at 2-, 6-, 12- and 26-weeks post-surgery. There were no significant differences in postoperative complication rates between the PWB and RWB groups.

CONCLUSION

PWB is effective and is associated with a significantly reduced time to full weight bearing, and a significantly better outcome regarding ADL and QoL compared to patients who followed RWB regimen. Moreover, no significant differences in complication rates were found between the PWB and RWB groups.

LEVEL OF EVIDENCE

Level II.

How to measure success in lower extremity reconstruction, which outcome measurements do we use a systematic review and metanalysis

Different factors have to be considered and weighted in the treatment algorithm of lower extremity reconstruction. A combination of both clinicians' and patients' perspectives is necessary to provide a conclusive picture. Currently, there aren't any standardized and validated measurement data sets for lower extremity reconstructions. This makes it necessary to identify the relevant domains. We, therefore, performed a systematic review and metanalysis of outcome measurements and evaluated their ability to measure outcomes after lower extremity reconstruction. A systematic review and metanalysis according to the 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' protocol were performed for studies reporting at least one structured outcome measurement of lower extremity reconstruction. Both Patient (PROMs)- and Clinician reported outcome measurements (CROMs)were analyzed. Of the 2827 identified articles, 102 were included in the final analysis. In total 86 outcome measurements were identified, 34 CROMs, 44 PROMs and 8 (9.3%) outcome measurements that have elements of both. Twenty-four measure functional outcome, 3 pain, 10 sensations and proprioception, 9 quality of life, 8 satisfaction with the result, 5 measure the aesthetic outcome, 6 contours and flap stability and 21 contain multidomain elements. A multitude of different outcome measurements is currently used in lower extremity reconstruction So far, no consensus has been reached on what to measure and how. Validation and standardization of both PROMs and CROMs in plastic surgery is needed to improve the outcome of our patients, better meet their needs and expectations and eventually optimize extremity reconstruction by enabling a direct comparison of studies' results.

Patient-reported outcomes following free flap lower extremity reconstruction: A systematic review and meta-analysis

PURPOSE

Free flap reconstruction in the lower extremity has shown success for the management of large and complex defects, restoration of function, and favorable aesthetic outcomes. Patient-reported outcomes (PROs) have not been well explored in previous literature. This meta-analysis aimed to provide a comprehensive summary of PROs after free flap reconstruction in the lower extremity.

METHODS

We searched MEDLINE and Embase from 1946 to 2021 for studies reporting on PROs following free flap reconstruction in the lower extremity.

RESULTS

Overall, 53 studies were included, and 11 studies reported validated PRO measures for meta-analysis. A total of 1953 patients underwent reconstruction with 1958 free flaps for lower limb defects with a mean follow-up of 3.26 (0.25-7.83) months. The mean postoperative Lower Extremity Functional Scale (LEFS) scores were 60.3 (±12) out of 80 points (4 studies, 85 patients). The mean postoperative AOFAS scores were 75.1 (±15) out of 100 points (4 studies, 68 patients). The mean postoperative SF-36 scores were 88.1 (±8.0) out of 100 points; mental health component was 48.7 (±8.9), and physical component was 38.4 (±8.2), out of 50 points (4 studies, 88 patients).

CONCLUSION

Our findings demonstrated that patients report improved physical health, mental health, and function following lower extremity reconstruction with free flaps. Patients reported similar improvements in functional scores following lower extremity reconstruction regardless of their free flap type. Furthermore, patients with myocutaneous flaps may have improved mental health and worse physical health scores when compared to perforator flaps. The evidence profiles presented in this review indicate that additional research is needed to help guide future decision-making.

Synchronous circular frame stabilisation and microsurgical soft tissue reconstruction for open lower limb fractures-A cost analysis and description of the surgical technique

INTRODUCTION

Current surgical paradigms for ortho-plastic management of IIIB open tibial fractures make compromises. Often, definitive circular frame stabilisation is delayed until the soft tissue envelope is secure to allow access for further soft tissue reconstruction if required. This delay has potential clinical and cost implications. A previous study showed acute circular frame stabilisation performed concurrently or before soft tissue reconstruction was feasible without additional soft tissue reconstruction problems. This study examines potential resource savings using this approach.

METHODS

All open tibial fractures managed by circular fixator and microsurgical soft tissue reconstruction between April 2015 and June 2019 were identified from a prospectively maintained database. Those receiving circular frame stabilisation with synchronous microsurgical soft tissue reconstruction were considered cases; those in whom the frame stabilisation was delayed were controls. Cost data were derived from the Patient Level Information and Costing System. Salvage cases and those with incomplete treatment were excluded.

RESULTS

Nine cases and 25 controls were evaluated. No statistically significant difference was observed between groups in terms of age, sex, injury severity score, time to debridement, time to coverage, length of follow up, or time to union. Median length of stay was 13.3 and 19.7 days for cases and controls respectively (p<0.01). Cases required fewer procedures (2.3) compared to controls (4.5) (p<0.001). The cost of care was less for cases (£25,527) than controls (£32,952) (p <0.05). No cases returned to theatre with flap failure or flap compromise. Complications were similar between groups.

CONCLUSION

In suitable patients, synchronous circular frame stabilisation and microsurgical soft tissue reconstruction is a safe, clinically effective, and cost-saving option.

Treatment of Posttraumatic Tibial Diaphyseal Bone Defects: A Systematic Review and Meta-Analysis

OBJECTIVE

To describe evidenced-based treatment options for patients who sustained trauma and/or posttraumatic osteomyelitis of the tibia resulting in diaphyseal bone defects and to compare outcomes between patients treated with nonvascularized bone grafts (NBGs), bone transport (BT), or vascularized bone grafts (VBGs).

DATA SOURCE

The Preferred Reporting Items for Systematic Review and Meta-Analyses of individual participant data and Cochrane guidelines were followed. PubMed, EMBASE, Cochrane Library, Web of Science, Scopus, and CINAHL were searched from inception to June 2020.

STUDY SELECTION

Patients who were ≥18 years, had sustained trauma to the tibia resulting in fracture and/or osteomyelitis with measurable diaphyseal bone defects, and were treated by interventions such as NBGs, BT, or VBGs were eligible. Excluded studies were non-English, reviews, nonreviewed literature, cadavers, animals, unavailable full texts, nondiaphyseal defects, atrophic nonunions, malignancy, and replantations.

DATA EXTRACTION

A total of 108 studies were included with 826 patients. Two reviewers systematically/independently screened titles/abstracts, followed by full texts to ensure quality, accuracy, and consensus among authors for inclusion/exclusion of studies. A third reviewer addressed disagreements if investigators were unable to reach a consensus. Studies were quality assessed using "Methodological Quality and Synthesis of Case Series and Case Reports".

DATA SYNTHESIS

Analyses were performed with IBM SPSS version 25.0 (IBM Corporation, Armonk, NY) and G*Power3.1.9.2.

CONCLUSIONS

NBGs may be considered first line for trauma defect sizes ≤ 10 cm or posttraumatic osteomyelitis defect sizes <5 cm. BT may be considered first line for posttraumatic osteomyelitis defect sizes <5 cm. VBGs may be considered first line for trauma and posttraumatic osteomyelitis defect sizes ≥5 cm.

The economic burden of the postoperative management in surgically treated trauma patients with peri- and/or intra-articular fractures of the lower extremities: A prospective multicenter cohort study

OBJECTIVES

To estimate the economic burden expressed in costs and quality of life of the post-surgical treatment of peri‑ and/or intra-articular fractures in the lower extremity from a societal perspective.

DESIGN

This is a quantitative study as it aims to find averages and generalize results to wider populations. The design is a cost-of-illness and quality of life study focusing on costs (in euros), Activities of Daily Living (ADL) and Quality of Life (Qol) in patients with peri‑ and/or intra-articular fractures of the lower extremities.

SETTING

Surgically treated trauma patients with peri‑ and/or intra-articular fractures of the lower extremities during 26 weeks follow-up. Patients were included from 4 hospitals in the Netherlands.

MAIN OUTCOME MEASURES

Costs, ADL and Quality Adjusted Life Years (QALY).

METHODS

Cost of illness was estimated through a bottom-up method. The Dutch Eq-5D-5 L questionnaire was used to calculate utilities while Lower Extremity Functional Scale (LEFS) scores were used as a measure of ADL. Non-parametric bootstrapping was used to test for statistical differences in costs. Subgroup analyses were performed to determine the influence of work status and further sensitivity analyses were performed to test the robustness of the results.

RESULTS

Total average societal costs were € 9836.96 over six months. Unexpectedly, total societal and healthcare costs were lower for patients with a paid job relative to patients without. Sensitivity analyses showed that our choice of a societal perspective and the EuroQol as our primary utility measurement tool had a significant effect on the outcomes. The ADL at baseline was respectively; 10.4 and at 26 weeks post-surgery treatment 49.5. The QoL was at baseline respectively; 0.3 and at 26 weeks post-surgery treatment 0.7. These findings are indicative of a significantly improved ADL and QoL (p ≤ 0.05) over time.

CONCLUSIONS

This study reveal a substantial economic burden in monetary terms and effect on QoL of patients with peri‑ and/or intra-articular fractures of the lower extremities during 26 weeks follow-up.

Free flap transplantation combined with Ilizarov bone transport for the treatment of severe composite tibial and soft tissue defects

Objective

To evaluate the clinical efficacy of free flap transplantation combined with Ilizarov bone transport in the treatment of severe composite tibial and soft tissue defects.

Methods

We retrospectively analyzed the clinical data of 40 patients with severe composite tibial and soft tissue defects who underwent free flap transplantation combined with Ilizarov bone transport. The clinical efficacy was evaluated according to the following criteria: success rate of wound repair by free flap transplantation, incidence or recurrence rate of deep infection, healing rate of bone defects and external fixation index, incidence of complications, and functional score of affected extremities.

Results

All infections were generally well controlled by radical debridement and negative-pressure therapy, and all 40 patients’ wounds healed after repair and reconstruction of the tibia and soft tissues. Postoperative complications were alleviated by active treatment. The mean external fixation time was 12.83 ± 2.85 months, and the external fixation index was 1.55 m/cm. According to the Association for the Study and Application of Methods of Ilizarov (ASAMI) score, an excellent or good functional outcome was attained in 85% of patients.

Conclusion

Free flap transplantation combined with Ilizarov bone transport is an effective treatment for severe composite tibial and soft tissue defects.

Finnish translation and external validation of the Trauma Quality of Life questionnaire

BACKGROUND AND AIMS

Major trauma impairs health-related quality of life (HRQoL). The aim of this study was the Finnish translation and external validation of the Trauma Quality of Life (TQoL) questionnaire.

PATIENTS AND METHODS

The Finnish version of the TQoL questionnaire and the 15D, a generic HRQoL questionnaire, were sent by mail to 417 patients identified from the Helsinki Trauma Registry.

RESULTS

Altogether 222 patients (53.2%) returned the questionnaires. Participants' mean age was 49.9 ± 18.1 years and 68.8% were males. The mean 15D score was significantly lower than that of the age- and sex-standardized general Finnish population (0.817 vs. 0.918, p < 0.001). The correlation between the Finnish translation and 15D scores was high (0.805). Factor analysis revealed that the Finnish TQoL questionnaire and the 15D have four common factors. Internal validation identified some differences between the Finnish and the original versions.

CONCLUSIONS

The correlation between the Finnish TQoL questionnaire and the 15D was high. The factor structures of the original and Finnish versions of the TQoL questionnaire were not identical, which may be a consequence of cultural or patient population differences.Implications for rehabilitationTrauma causes a long-term decrease in health-related quality of life (HRQoL), and this impact should be assessed in rehabilitation.The Trauma-Specific Quality of Life (TQoL) questionnaire has many shared features with the generic HRQoL questionnaire, but it also contains features related to post-traumatic disorder syndrome.The TQoL questionnaire is a valid tool for monitoring HRQoL after trauma.

Bone Transport for Treatment of Traumatic Composite Tibial Bone and Soft Tissue Defects: Any Specific Needs besides the Ilizarov Technique?

Objective

To evaluate the surgical efficacy of bone transport (Ilizarov technique) plus “shortening-lengthening,” “flap surgery,” and “open bone transport” as individualized treatments for traumatic composite tibial bone and soft tissue defects.

Methods

We retrospectively analyzed sixty-eight cases (mean age: 35.69 years, (range, 16–65)) treated from July 2014 to June 2017, including 29 middle, 18 distal, and 21 proximal tibial bone defects (4–18 cm, mean: 7.97 cm) with soft tissue defects (2.5 cm × 4.0 cm to 30.0 cm × 35.0 cm after debridement). We adopted the bone transport external fixator to fix the fracture after debriding the defect parts. In the meantime, we adopted the “shortening-lengthening technique,” “flap surgery,” and “open bone transport” as individualized treatment based on the location, range, and severity of the composite tibial bone and soft tissue defects. Postoperative follow-up was carried out. Surgical efficacy was assessed based on (1) wound healing; (2) bone defect healing rate; (3) external fixation time and index; (4) incidence/recurrence of deep infection; (5) postoperative complications; and (6) Association for the Study and Application of the Methods of Ilizarov (ASAMI) score.

Results

The mean duration from injury to reconstruction was 22 days (4–80 d), and the mean postoperative follow-up period was 30.8 months (18–54 m). After the repair and reconstruction, 2 open bone transport patients required infected bone removal first before continuing the bone transport treatment. No deep infection (osteomyelitis) occurred or recurred in the remaining patients, and no secondary debridement was required. Some patients had complications after surgery. All the postoperative complications, including flap venous crisis, nail channel reaction, bone nonunion, mechanical axis deviation, and refracture, were improved or alleviated. External fixation time was 12.5 ± 3.41 months, and the index was 1.63 ± 0.44. According to the ASAMI score, 76.47% of the outcomes were good/excellent.

Conclusion

The Ilizarov technique yields satisfactory efficacy for composite tibial bone and soft tissue defects when combined with “shortening-lengthening technique,” “flap surgery,” and “open bone transport” with appropriate individualized treatment strategies.

Management of Post-Traumatic Composite Bone and Soft Tissue Defect of Leg

Management of composite defects of leg following trauma requires a planned ortho-plastic approach right from the outset. Timely, planned intervention results in reduced amputation rates and improved limb salvage and function. Right from the time of presentation of the patient to the emergency with such injury, the process of decision making in terms of salvage or amputation, local flap cover/free flap cover, bone reconstruction first or soft tissue or both combined, come into play. Guidelines on management are unclear for such defects, a literature search yielding various methods being used by different authors.

This article is a review of current literature on management of composite leg defects.

A summary of the literature search in terms of various management options given by various authors including the rationale, advantages and disadvantages of each strategy has been provided in this article. The management protocol and method followed by the author in his institute for management of such composite defects have been described in detail. The article seeks to provide readers with an understanding of the management strategies so that appropriate method could be chosen to provide best result.

Immediate Soft-Tissue Reconstruction for Chronic Infected Tibia Nonunions Treated with an Ilizarov Frame. Plast Reconstr Surg Glob Open. 2019;7:e2180. [PMID: 31044132 PMCID: PMC6467626 DOI: 10.1097/gox.0000000000002180]

There are multiple options available for the management of large tibial defects. The Ilizarov frame is one of the most widely used techniques due to the physiological bone growth and the symmetrical distribution of axial forces permitting adequate bone distribution. However, disadvantages still remain including obtaining additional soft-tissue access for defect coverage. We present our experience with soft-tissue reconstruction for chronic infected tibial nonunions using free tissue transfers simultaneously with Ilizarov device placement. A retrospective review was performed from 2014 to 2016 of patients presenting with a chronically infected tibia nonunion and treated by our senior orthopedic and plastic surgeons. Demographic data, comorbidities, intraoperative details and postoperative outcomes were collected. A total of 6 patients were identified with a mean age of 46.2 ± 11.6 years. Complete flap survival and resolved active infection were achieved in 5 of our patients, 4 demonstrated body union on imaging, and all of them reached complete ambulance. Flap revisions with allografting for partial flap loss were performed in 1 patient. Preoperative planning is critical for immediate lower extremity reconstruction in the setting of an Ilizarov frame. From our institutional experience, free tissue transfer can safely be placed after frame placement.

Permissive weight bearing in trauma patients with fracture of the lower extremities: prospective multicenter comparative cohort study

Background

The standard aftercare treatment in surgically treated trauma patients with fractures around or in a joint, known as (peri)- or intra-articular fractures of the lower extremities, is either non-weight bearing or partial weight bearing. We have developed an early permissive weight bearing post-surgery rehabilitation protocol in surgically treated patients with fractures of the lower extremities. In this proposal we want to compare our early permissive weight bearing protocol to the existing current non-weight bearing guidelines in a prospective comparative cohort study.

Methods/design

The study is a prospective multicenter comparative cohort study in which two rehabilitation aftercare treatments will be contrasted, i.e. permissive weight bearing and non-weight bearing according to the AO-guideline. The study population consists of patients with a surgically treated fracture of the pelvis/acetabulum or a surgically treated (peri)- or intra-articular fracture of the lower extremities. The inclusion period is 12 months. The duration of follow up is 6 months, with measurements taken at baseline, 2,6,12 and 26 weeks post-surgery.

Primary outcome measure: ADL with Lower Extremity Functional Scale. Outcome variables for compliance, as measured with an insole pressure measurement system, encompass peak load and step duration.

Discussion

This study will investigate the (cost-) effectiveness of a permissive weight bearing aftercare protocol. The results will provide evidence whether a permissive weight bearing protocol is more effective than the current non-weight bearing protocol.

Trial registration

The study is registered in the Dutch Trial Register (NTR6077). Date of registration: 01–09-2016.

Staged reconstruction of diaphyseal fractures with segmental defects: Surgical and patient-reported outcomes

INTRODUCTION

Two-stage limb reconstruction is an option for patients with critical size segmental bone defects following acute trauma or non-union. Reconstruction is technically demanding and associated with a high complication rate. Current protocols for limb reconstruction have well-documented challenges, and no study has reported on patient outcomes using a validated questionnaire. In this study, we aimed to examine the clinical and patient-centered outcomes following our surgical protocol for two-stage limb reconstruction following critical size segmental defects.

PATIENTS AND METHODS

A single surgeon performed reconstruction of long bone defects using antibiotic impregnated cement spacers and intramedullary cancellous bone autograft. A retrospective chart review was performed. Three reviewers independently measured time to union based on radiographs. The Lower Extremity Functional Scale (LEFS) survey was administered to patients after most recent follow-up.

RESULTS

Ten limbs representing nine patients were included. All patients sustained a lower extremity injury, and one patient had bilateral lower extremity injuries. Average clinical follow-up was 18.3 months (range 7-33) from final surgical intervention, and follow-up to questionnaire administration was 28 months (range 24-37). The mean time between stages was 3.1 months. Average time to unrestricted weight-bearing was 7.9 months from Stage 1 (range 3.4-15.9) and 4.5 months from Stage 2 (range 1.1-11.6). Average time to full union was 16.7 months from Stage 1 (range 6.4-28.6) and 13.5 months from Stage 2 (range 1.8-27). Eight patients (nine limbs) participated in the LEFS survey, the average score was 53.1 (range 30-67), equating to 66% of full functionality (range 38%-84%). Complications included 5 infections, 3 non-unions, and one amputation. There was a moderate positive correlation between infection at any time point and non-union (R=0.65, p=0.03).

DISCUSSION AND CONCLUSIONS

Outcomes in this small patient cohort were good despite risks of complication. There is an association between infection and non-union. Further studies addressing clinical and functional outcomes will help to guide expectations for future surgeons and patients.
