ABSTRACT
Foot-drop is one of the most diagnosed and physically limiting symptoms persons with multiple sclerosis (pwMS) experience. Clinicians prescribe ankle-foot orthosis (AFO) and functional electrical stimulation (FES) devices to help alleviate the effects of foot drop, but it is unclear how their clinical and functional gait improvements compare given the user's level of disability, type of multiple sclerosis, walking environment, or desired physical activity. The research questions explored were what is the current state of AFO and FES research for pwMS? What are the prevailing research trends? What definitive clinical and functional device comparisons exist for pwMS? eight databases were systematically searched for relevant literature published between 2009 and 2021. The American Association of Orthotists and Prosthetists and Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines for systematic literature reviews were followed. A team of 3 researchers critically evaluated 17 articles that passed eligibility criteria. This review discusses the current state and trends of research, provides evidence statements on device effects, and recommends improvements for future studies. A meta-analysis would be informative, but study variability across the literature makes directly comparing AFO and FES device effects unreliable. This review contributes new and useful information to multiple sclerosis literature that can be used by both clinicians and researchers. Clinicians can use the provided insights to prescribe more effective, customized treatments, and other researchers can use them to evaluate and design future studies.

BACKGROUND: Foot drop is a common complication in post-stroke. Patients with foot drop are at high risk for falls and fall-related injuries. Accordingly, it can reduce independence and quality of life in patients. Clinical studies have confirmed that acupuncture is effective in treating foot drop in post-stroke. However, there is a lack of systematic review exploring the efficacy and safety of acupuncture treatment. This study aims to assess the efficacy and safety of acupuncture in the treatment of foot drop in poststroke from the results of randomized controlled trials. METHODS: We will search articles in 8 electronic databases including the Cochrane Central Register of Controlled Trials, the Web of Science, PubMed, Embase, the China National Knowledge Infrastructure, the Chinese Biomedical Literature Database, Wanfang Data Database, and the Chinese Scientific Journal Database for RCTs of acupuncture treated foot drop in post-stroke from their inception to 10 August 2022. We will analyze the data meeting the inclusion criteria with the RevMan V.5.4 software. Two authors will assess the quality of the study with the Cochrane collaborative risk bias tool. We will evaluate the certainty of the estimated evidence with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method. Data analysis will be performed using STATA 16.0. RESULTS: This study will review and evaluate the available evidence for the treatment of foot drop in post-stroke using acupuncture. CONCLUSION SUBSECTIONS: This study will determine the efficacy and safety of acupuncture applied to post-stroke individuals with foot drop.

Peripheral neuropathy secondary to entrapment of the nerves is not an uncommon etiology. Nerve entrapment is a common occurrence following trauma or surgery and poses significant diagnostic challenge. Entrapment neuropathy (EN) may not respond to standard neuropathic medication and may need invasive treatment. Pulsed radiofrequency (PRF) application is a recent modality and is gaining popularity for many EN as it does not cause neural ablation unlike conventional radiofrequency ablation. In this report, we present a case of young patient who presented with severe lower lateral leg pain in whom superficial peroneal nerve (SPN) EN was suspected and diagnostic SPN injection under ultrasound guidance confirmed the diagnosis. He subsequently underwent PRF neuromodulation and experienced long-lasting pain relief.

BACKGROUND AND PURPOSE: Daily management of patients with foot drop due to peroneal nerve entrapment varies between a purely conservative treatment and early surgery, with no high-quality evidence to guide current practice. Electrodiagnostic (EDX) prognostic features and the value of imaging in establishing and supplementing the diagnosis have not been clearly established. METHODS: We performed a literature search in the online databases MEDLINE, Embase, and the Cochrane Library. Of the 42 unique articles meeting the eligibility criteria, 10 discussed diagnostic performance of imaging, 11 reported EDX limits for abnormal values and/or the value of EDX in prognostication, and 26 focused on treatment outcome. RESULTS: Studies report high sensitivity and specificity of both ultrasound (varying respectively from 47.1% to 91% and from 53% to 100%) and magnetic resonance imaging (MRI; varying respectively from 31% to 100% and from 73% to 100%). One comparative trial favoured ultrasound over MRI. Variable criteria for a conduction block (>20%-≥50) were reported. A motor conduction block and any baseline compound motor action potential response were identified as predictors of good outcome. Based predominantly on case series, the percentage of patients with good outcome ranged 0%-100% after conservative treatment and 40%-100% after neurolysis. No study compared both treatments. CONCLUSIONS: Ultrasound and MRI have good accuracy, and introducing imaging in the standard diagnostic workup should be considered. Further research should focus on the role of EDX in prognostication. No recommendation on the optimal treatment strategy of peroneal nerve entrapment can be made, warranting future randomized controlled trials.

Purpose: Various postoperative protocols have been proposed to improve outcomes and accelerate nerve regeneration. Recently, the use of physical exercise in a post-surgical neurorraphy procedure has shown good results when started early. We experimentally investigated the hypothesis that post-operative exercise speeds up results and improves clinical and morphologic parameters. Methods: Isogenic rats were randomly divided into four groups: 1 SHAM; 2 SHAM submitted to the exercise protocol (EP); 3 Grafting of the sciatic nerve; and 4 Grafting of the sciatic nerve associated with the EP. The EP was based on aerobic activities with a treadmill, with a progressive increase in time and intensity during 6 weeks. The results were evaluated by the sciatic functional index (SFI), morphometric and morphologic analysis of nerve distal to the lesion, and the number of spinal cord motor neurons, positive to the marker Fluoro-Gold (FG), captured retrogradely through neurorraphy. Results: Functional analysis (SFI) did not show a statistical difference between the group grafted with (50.94) and without exercise (-65.79) after 90 days. The motoneurons count (Spinal cord histology) also showed no diference between these groups (834.5 × 833 respectively). Although functionally there is no difference between these groups, morphometric study showed a greater density (53.62) and larger fibers (7.762) in GRAFT group. When comparing both operated groups with both SHAM groups, all values were much lower. Conclusions: The experimental model that this aerobic treadmill exercises protocol did not modify nerve regeneration after sciatic nerve injury and repair with nerve graft.

OBJECTIVE: To investigate the clinical effect of mouse nerve growth factor (mNGF) and methylcobalamin (MeCbl) for the treatment of lumbar disk herniation (LDH) with foot drop. METHODS: A total of 46 patients suffering from LDH with foot drop who underwent transforaminal lumbar interbody fusion (TLIF) surgery in our department from January 2015 to December 2017 were retrospectively analyzed. We divided these patients into two groups according to the different postoperative treatment which independently selected by patients after signing informed consent form: one group of 25 patients was treated with MeCbl alone (Group MeCbl), the other group of 21 patients was treated with a combination of mNGF and MeCbl (Group MeCbl+mNGF). Patient demographics, the visual analogue scale (VAS) scores, sensory and muscular strength improvement statistics at 1 week, 4 weeks, 12 weeks, and 12 months postoperatively were recorded. Motor/sensory deficits, sciatica and overall neurological outcome after treatment of MeCbl alone and combination of mNGF and MeCbl were retrospectively analyzed. RESULTS: The follow-up ranged between 12 and 42 months (mean 20.8 months). There were no significant differences between these two groups of patients with respect to sex ratio, age, smoking, diabetes, disease course, section of protruding disc(s), muscular strength of foot dorsiflexion or preoperative visual analogue scale (VAS) score (P > 0.05). The VAS scores of Group MeCbl+mNGF were significantly lower than Group MeCbl at 1 week, 4 weeks, 12 weeks, and 12 months postoperatively (4.32 ± 0.75 vs 5.25 ± 0.79,2.65 ± 0.48 vs 3.42 ± 0.52, 1.72 ± 0.36 vs 2.45 ± 0.39, 1.12 ± 0.22 vs 1.52 ± 0.24, P < 0.05). The effective rates of sensory improvement were significantly higher in Group MeCbl+mNGF compared with Group MeCbl at 12-week/12-month follow-up time point (90.48% vs 52.00%,95.24% vs 68.00%, P < 0.05). The effective rate of muscular strength improvement of the two groups did not differ significantly at 1 week after surgery but exhibited statistically significant differences at subsequent time points (61.90% vs 32.00%, 76.19% vs 44.00%, 80.95% vs 48.00%, P < 0.05). CONCLUSIONS: Application of mNGF had clinical effects on promoting the recovery of neurological function in patients suffering from LDH with foot drop.

The main purpose of the present study was to assess the effects of foot drop stimulators (FDS) in individuals with stroke by means of spatio-temporal and step-to-step symmetry, harmonic ratio (HR), parameters obtained from trunk accelerations acquired using a wearable inertial sensor. Thirty-two patients (age: 56.84 ± 9.10 years; 68.8% male) underwent an instrumental gait analysis, performed using a wearable inertial sensor before and a day after the 10-session treatment (PRE and POST sessions). The treatment consisted of 10 sessions of 20 min of walking on a treadmill while using the FDS device. The spatio-temporal parameters and the HR in the anteroposterior (AP), vertical (V), and mediolateral (ML) directions were computed from trunk acceleration data. The results showed that time had a significant effect on the spatio-temporal parameters; in particular, a significant increase in gait speed was detected. Regarding the HRs, the HR in the ML direction was found to have significantly increased (+20%), while those in the AP and V directions decreased (approximately 13%). Even if further studies are necessary, from these results, the HR seems to provide additional information on gait patterns with respect to the traditional spatio-temporal parameters, advancing the assessment of the effects of FDS devices in stroke patients.

Impaired mobility is common in people with multiple sclerosis (MS). Changes in gait have different causes and require individualised gait rehabilitation. A common and often early cause of mobility impairment is footdrop, inability to lift the foot during the swing phase of gait, with increased risk of falls, effortful walking and fatigue. Using literature review, we have characterised published data on footdrop treatment in MS, specifically functional electrical stimulation (FES) to better understand the reported outcomes relevant to the user. We discuss the strengths and weaknesses of FES and how far it meets the needs of people with footdrop. Physiotherapy combined with FES may further enhance the benefits of FES. MS studies emphasise the value of maintaining activity levels in early MS but discussion on how to achieve this is lacking. We emphasise the value of qualitative measures to broaden our understanding and improve treatment and adherence and identify areas for further research. Supplementary video material illustrates key features of MS gait and its correction using FES and physiotherapy.

BACKGROUND: Functional electric stimulation (FES) is recommended for foot drop in multiple sclerosis, although little is known about its therapeutic effect. AIM: The aim of this study is to evaluate a therapeutic effect immediately and two months after program termination (persistent and delayed effect) of a new approach using FES in combination with correcting the patients' postural system. More specifically, we evaluate the effects of this approach on the patients' clinical functions and compared it with individual physiotherapy. DESIGN: Parallel randomized blind trial. SETTING: Two-month-long treatments, functional electric stimulation in posturally corrected position (group 1) and neuroproprioceptive facilitation and inhibition physiotherapy called motor program activating therapy (group 2). POPULATION: Forty-four subjects with multiple sclerosis. METHODS: Primary outcomes: gait (the 2-Minute Walk Test; Timed 25-Foot Walk test; Multiple Sclerosis Walking Scale-12) and balance (by e.g. Berg Balance Scale [BBS], the Activities-Specific Balance Confidence Scale [ABC], Timed Up-and-Go Test [TUG]). SECONDARY OUTCOMES: mobility, cognition, fatigue and subjects' perceptions (e.g. Multiple Sclerosis Impact Scale [MSIS], Euroqol-5 dimensions-5 levels [EQ-5D-5L]). RESULTS: Group 1 showed immediate therapeutic effect in BBS (P=0.008), ABC (P=0.04) and EQ-5D-5L (self-care, P=0.019, mobility P=0.005). The improvement in EQ-5D-5L persisted and in TUG-cognitive we documented a delayed effect (P=0.005). Group 2 showed an immediate improvement in BBS (P=0.025), MSIS (P=0.043) and several aspects of daily life (the effect on health today was significantly higher than in group 1, significant difference between groups P=0.038). CONCLUSIONS: FES in the posturally corrected position has an immediate therapeutic effect on balance and patients' perceptions comparable to motor program activating therapy, and higher persistent and even delayed therapeutic effect. CLINICAL REHABILITATION IMPACT: The study results point to the importance of correcting the patients' posture when applying FES, the possibility to treat foot drop by individual physiotherapy and the activation of the patients' auto reparative processes.

Purpose: Functional electrical stimulation (FES) is effective in improving walking in people with multiple sclerosis (MS) with foot drop. There is limited research exploring people's experiences of using this device. This study aims to explore the utility, efficacy, acceptability, and impact on daily life of the device in people with MS.Methods: An interpretative phenomenological approach was employed. Ten participants who had used FES for 12 months were interviewed. Transcripts were analysed, and emergent themes identified.Results: Nine participants continued to use the device. Three relevant super-ordinate themes were identified; impact of functional electrical stimulation, sticking with functional electrical stimulation, and autonomy and control. Participants reported challenges using the device; however, all reported positive physical and psychological benefits. Intrinsic and external influences such as; access to professional help, the influence of others, an individual's ability to adapt, and experiences using the device, influenced their decisions to continue with the device. A thematic model of these factors was developed.Conclusions: This study has contributed to our understanding of people with MS experiences of using the device and will help inform prescribing decisions and support the continued, appropriate use of FES over the longer term.Implications for RehabilitationPeople with multiple sclerosis using functional electrical stimulation report benefits in many aspects of walking, improved psychological well-being and increased engagement in valued activities.A number of challenges impact on functional electrical stimulation use. Factors such as; a positive experience using the device, access to professional help, the influence of others, a strong sense of personal autonomy and an individual's ability to adapt, influence an individual's decision to continue using functional electrical stimulation.Clinicians prescribing functional electrical stimulation should be aware of these factors so that the right support and guidance can be provided to people with multiple sclerosis, thus improving outcomes and compliance over the long term.

RATIONALE: Most cases of foot drop are known to result from lower motor neuron pathologies, particularly lumbar radiculopathy and peripheral neuropathy, including common peroneal neuropathy. To improve the prognosis of foot drop, it is important to quickly and accurately diagnose the etiology and provide appropriate treatment. PATIENT CONCERNS: A 65-year-old female patient with a history of L4-5 intervertebral disc herniation presented with right foot drop that had developed 1 month previously. DIAGNOSIS: Electrodiagnostic examination revealed common peroneal neuropathy combined with L5 radiculopathy, with the former being the main cause of the foot drop. MRI of the right knee was performed to identify the cause of the peroneal nerve lesion, which revealed an intraneural ganglion cyst in the common peroneal nerve. INTERVENTIONS: The patient was treated by ultrasound-guided percutaneous cyst aspiration and corticosteroid injection into the decompressed ganglion, followed by strengthening exercise, electrical stimulation therapy, and prescription of an ankle foot orthosis. OUTCOMES: We confirmed regeneration of the injured peroneal nerve at the follow-up electrodiagnostic examination 12 weeks after the intervention. In addition, the manual motor power test demonstrated an increase in the ankle dorsiflexor function score by one grade. LESSONS: Diagnosing the cause of foot drop can be difficult with multiple co-existing pathologies, and consideration of various possible etiologies is the key for appropriate diagnosis and treatment. In addition to imaging modalities such as MRI, electrodiagnostic examination can help to improve diagnostic accuracy. Intraneural ganglion cyst of the common peroneal nerve is rare, but should be considered as a possible cause of foot drop.

OBJECTIVES: The purpose of this study is to assess the immediate effects of applying ankle eversion taping using kinesiology tape in patients with foot drop after stroke. DESIGN: Randomized cross-over trial. METHOD: In this study, fifteen subjects with stroke underwent three interventions in a random order. Subjects were randomly initially assigned to an ankle balance taping, placebo taping, and no taping each group. The ankle eversion taping was used for mechanical correction. Ankle eversion taping is involved in ankle dorsiflexion and eversion. The placebo taping began from both malleolus and was applied up to the middle point of the lower limb. Gait ability was assessed by the GAITRite System. The measured gait variables are gait velocity, step length, stride length, H-H base support, and cadence. All of the measurements were performed immediately after intervention. RESULTS: Our results showed gait function in chronic stroke patients was improved after ankle eversion taping. Velocity, step length, stride length and cadence under the ankle eversion taping conditions significantly increased (pâ¯<â¯0.05) compared to the placebo and no taping conditions. Ankle eversion taping significantly reduced (pâ¯<â¯0.05) H-H base support compared to the no taping condition. CONCLUSIONS: We conclude that the application of ankle eversion taping that uses kinesiology tape instantly increased the gait ability of chronic stroke patients with foot drop. However, more research is necessary to identify the long-term effects of the ankle eversion taping.

BACKGROUND: Foot drop can be caused by a variety of diseases and injuries. Although it is a common condition, its overall incidence has not been reported to date. Foot drop markedly restricts the everyday activities of persons suffering from it. There is, therefore, a need for an optimized strategy for its diagnosis and treatment that would be standardized across the medical specialties encountering patients with this problem. METHODS: This article consists of a review on the basis of pertinent publications re- trieved by a search in the Pubmed/MEDLINE and Cochrane databases, as well as a description of the authors' proposed strategy for the diagnosis and treatment of foot drop. RESULTS: Foot drop can be due to a disturbance at any central or peripheral location along the motor neural pathway that terminates in the dorsiflexor muscles of the foot, or at multiple locations in series. Optimal localization of the lesion(s) is a pre- requisite for appropriate treatment and a successful outcome. The most common causes are L5 radiculopathy and peroneal nerve injury. An operation by a neuro- surgeon or spinal surgeon is a reasonable option whenever there is a realistic chance that the nerve will recover. In our opinion, any patient with a subjectively disturbing foot drop and a clinically suspected compressive neuropathy of the peroneal nerve should be informed about the option of surgical decompression of the nerve at the fibular head, which can be performed with little risk. In case of a permanent foot drop, some patients can benefit from muscle-transfer surgery. For spastic foot drop, the option of botulinum toxin injections should be evaluated. CONCLUSION: The care of patients with foot drop could be optimized by interdisciplin- ary foot-drop clinics involving all of the relevant specialists. The goals of treatment should always be improved mobility in everyday life and the prevention of falls, pain, and abnormal postures.

OBJECTIVE: To compare the therapeutic effect of fire-needling plus stuck-needle-stretching and conventional acupuncture for post-stroke foot drop, so as to provide a reference foundation for optimizing clinical treatment regimen. METHODS: A total of 60 patients with post-stroke foot drop were equally randomized into a treatment group and a control group. In the treatment group, fire-needling plus stuck-needle-stretching was applied to acupoint pairs Jiexi (ST41)-Taichong (LR3), Xiajuxu (ST39)-ST41, Fenglong (ST40)-ST39, shangjuxu (ST37)-ST40, Zusanli (ST36)-ST37, Dubi (ST35)-ST36, Xuanzhong (GB39)-Qiuxu (GB40) on the affected side, and Chengshan (BL57) and Ashi points were swiftly pricked with red-hot filiform needle without needle retaining. In the conventional acupuncture group, the same acupoints were needled with filiform needles, and the treatment for both groups was given once a day, 6 times a week, for consecutive 4 weeks. The spasm severity of posterior triceps of the lower leg was evaluated using modified Ashworth scale, the tibial anterior muscle strength was measured using Lovett' and Martin's methods, the activities of daily living were assessed using modified Barthel's index, the walking ability was evaluated using Holden walking rating scale and the lower limb motor function assessed using Fugl-Meyer assessment scale, and the severity of foot drop was assessed in reference to Garceau criteria. RESULTS: After the treatment, the score of the modified Ashworth scale was significantly reduced (P<0.01), and those of Lovett muscle strength scale, Barthel index, Holden walking rating scale and Fugl-Meyer lower limb motor function scale were considerably increased in both groups versus their own pre-treatment (P<0.01). The therapeutic effect of the treatment group was significantly superior to that of the control group in reducing Ashworth scale score and in increasing the scores of Lovett muscle strength test, Barthel index, Holden walking function scale and Fugl-Meyer lower limb motor function scale (P<0.01). Of the two 30 cases in the control and treatment groups, 10(33.33%)and 14(46.67%) experienced a remarkable improvement, 10(33.33%)and 12(40.00%)were improved, 7(23.33%)and 3(10.00%)had a mild progress, 3(10.00%) and 1(3.33%) failed, with the excellent plus good effective rates being 66.67% and 86.67%, respectively, but without significant difference between the two groups (P>0.05). CONCLUSION: Both fire-needling plus stuck-needle-stretching and conventional acupuncture are effective in the treatment of post-stroke foot drop, but the former is relatively better.

BACKGROUND: Implanted peroneal functional electrical stimulation (FES) is an effective alternative treatment to ankle-foot orthosis (AFO) in people with drop foot after stroke. With FES no constraints on ankle mobility are imposed which might particularly be exploited in challenging walking environments that require adaptations of the gait pattern to environmental disturbances. RESEARCH QUESTION: Is gait adaptability, by means of the capacity to avoid sudden obstacles while walking on a treadmill, superior with implanted FES compared to AFO in people with drop foot after stroke? METHODS: A 4-channel peroneal nerve stimulator (ActiGait®) was implanted in 22 persons with stroke (>6 months) who regularly used an AFO. Gait adaptability was tested with an obstacle avoidance task on an instrumented treadmill up to 26 weeks (n = 10) or 52 weeks (n = 12) after FES-system activation. At assessments, 30 trials, in which obstacles were suddenly dropped onto the treadmill in front of the paretic leg, were recorded with each device (FES / AFO). Trials were grouped by available response times (ART) and success rates were calculated. The effect of device, ART and follow up time on success rates was tested using generalized estimated equations. Nonparametric correlations were calculated to associate changes in success rates with clinimetrics. RESULTS: Success rates of obstacle avoidance were higher when participants used their FES system compared to AFO (Δ4.7%, p = 0.03), which effect was largest for longest ARTs (Δ15%, p = 0.03). Participants with greater motor impairment of the paretic leg showed greater benefit from FES (rs=-0.49, p = 0.04). SIGNIFICANCE: FES has been found equally effective as AFO in improving walking speed of people with drop foot after stroke. We now present superior walking performance in a complex walking environment for implanted peroneal FES compared to AFO. These findings underline the importance of using gait assessments that require interplay with the environment, besides assessment of stationary walking, in community ambulators.

OBJECTIVE: Neurogenic drop foot is a common result of acquired damage of the central nervous system and can cause severe restriction of mobility. ActiGait, an implantable functional electrical stimulation device, restores ankle dorsiflexion by active peroneal nerve stimulation. The aim of our study was to evaluate its effect on foot contact pattern during normal walk. METHODS: Eight patients with drop foot who used ActiGait in everyday life performed a 20-meter comfortable walk test. Gait parameters were evaluated with an insole system (Medilogic). Percentage of biped stance in a double-step, effective foot length, width of gait, and overall plantar load were measured in comparison with and without activated drop foot stimulation. RESULTS: Effective foot length increased in all patients on average from 46.0% to 60.2% (P = 0.038). However, percentage of biped stance in a double-step showed no significant difference (31.2% vs. 27.8% on average, P = 0.063), nor did width of gait (2.6% vs. 2.4% on average, P = 0.73) and overall plantar load (3.51 N/cm2 vs. 3.39 N/cm2, P = 0.25). CONCLUSION: The ActiGait implantable drop foot stimulator significantly improves effective foot length during normal walk of patients with neurogenic drop foot. Further investigation is needed to confirm whether ActiGait has no effect on the other parameters or whether it facilitates permanent gait adaptations that persist without the activated device.

BACKGROUND: Multi-drug-resistant bacteria (e.g. Carbapenem-resistant Acinetobacter baumannii, extended-spectrum betalactamase or carbapenemase-producing enterobacteriaceae) are emerging in early-onset infections. So far, there is no report describing the eradication of these bacteria in a osseous infection of an open proximal tibial fracture in combination with the hexapod technology to address both osseous consolidation and closed drop foot correction. CASE PRESENTATION: After sustaining a proximal tibial fracture (Gustilo 3B), a 41-year-old man was primarily treated with open reduction and internal fixation by a locking plate and split-thickness skin graft in the home country. At the time of admission to our hospital there was a significant anterolateral soft tissue defect covered with an already-necrotic split-thickness graft and suspicious secretion. CAT and MRI scans revealed no signs of osseous healing, intramedullary distinctive osteomyelitis, as well as a large abscess zone in the dorsal compartment. Multiple wound smears showed multi-drug-resistant bacteria: Acinetobacter baumannii (Carbapenem resistant) as well as Enterobacter cloacae complex (AmpC overexpression). After implant removal, excessive osseous and intramedullary debridements using the Reamer Irrigator Aspirator (RIA®) as well as initial negative pressure wound therapy were performed. Colistin hand-modelled chains and sticks were applied topically as well as an adjusted systemic antibiotic scheme was applied. After repetitive surgical interventions, the smears showed bacterial eradication and the patient underwent soft tissue reconstruction with a free vascularized latissimus dorsi muscle flap. External fixation was converted to a hexapod fixator (TSF®) to correct primary varus displacement, axial assignment and secure osseous healing. A second ring was mounted to address the fixed drop foot in a closed fashion without further intervention. At final follow-up, 12 months after trauma, the patient showed good functional recovery with osseous healing, intact soft tissue with satisfactory cosmetics and no signs of reinfection. CONCLUSIONS: A multidisciplinary approach with orthopaedic surgeons for debridement, planning and establishing osseous and joint correction and consolidation, plastic surgeons for microvascular muscle flaps for soft tissue defect coverage as well as clinical microbiologists for the optimized anti-infective treatment is essential in these challenging rare cases. LEVEL OF EVIDENCE: Level IV.
