Foot Problems in Older Adults Presenting to a Falls and Balance Clinic.

INTRODUCTION: Foot problems, including musculoskeletal problems, peripheral neuropathy, peripheral arterial disease and dermatologic pathology are common in older adults and are associated with an increased risk of falling. Multicomponent podiatry interventions have been shown to reduce the incidence of falls. This paper aimed to identify older adults requiring podiatry input in a Falls and Balance clinic; to describe the model of foot health care they receive; to explore cross-sectional associations between foot problems and function and ultimately demonstrate the role of podiatry input in the multidisciplinary management of falls risk. METHODS: Cohort study of patients attending a Falls and Balance Clinic for Comprehensive Geriatric Assessment. Demographic information was collected and functional independence, mobility, foot problems, and footwear were assessed in the clinic. RESULTS: One-hundred and two patients were included; median age 79.3 (73-84.3) years, 68.6% female, 93.1% residing independently, 62.7% used a gait aid. Podiatry referrals were made in 80.4% of cases, with muscle weakness being the most common problem identified (90.2%); 74.8% were found to be wearing inappropriate footwear. Most patients received footwear education and half were prescribed foot and ankle strengthening exercises. Hallux and lesser toe weakness were associated with lower Short Physical Performance Battery scores (p < 0.001). CONCLUSION: The majority of older adults in the Falls and Balance Clinic required podiatry input, with foot weakness and inappropriate footwear being common reasons for referral. Those with weakness of the hallux and lesser toes had poorer balance and mobility, which is known to be associated with greater falls risk. This highlights the need for podiatry assessment and interventions as part of the multidisciplinary approach to the management of falls risk in older adults.

Verrucous Carcinoma of the Foot: A Single Canadian Center Experience on Diagnosis, Management, and Outcomes.

INTRODUCTION: Verrucous carcinoma (VC) was first described in 1948 by Dr. Ackerman. It is a low-grade cutaneous squamous carcinoma that usually develops in the oral cavity, the anogenital region, and the plantar surface of the foot. Clinically, there is low suspicion for malignancy given the slow growth of VC lesions and their wart-like appearance. Diagnosis can be difficult because of the benign histological appearance with well-differentiated cells and absence of dysplasia. Surgical excision is the only satisfactory form of treatment for plantar VC; however, this becomes difficult given its benign clinical appearance and the pathologic misinterpretation of the lesion as a benign hyperplasia. While there are case reports and retrospective studies of patients with plantar VC in the literature, we present the largest case series of plantar VC within North America, with recurrence despite negative margins. METHODS: We report on all the plantar VC excised between 2014-2023. We report six cases of VC, their treatment, and their outcomes. RESULTS: Six patients obtained a diagnosis of plantar VC by incisional biopsy. All patients underwent excision of their lesions and had negative margins reported on the final pathology. All patients developed nonhealing wounds at the site of their lesion excision; therefore, biopsies were performed to confirm a recurrence. All patients had a recurrence of VC at the initial site. All patients underwent re-excision of the lesions. Despite negative margins again on final pathology, all patients had a subsequent second recurrence. Ultimately, all patients underwent an amputation as definitive management. Each patient had an average of 3 operations. There were 4 different surgeons and different pathologists reporting their findings. CONCLUSIONS: Our experience with plantar VC suggests that an aggressive approach to surgical management is needed. Furthermore, management is optimized with the combined expertise of an experienced dermatopathologist and surgeon. Despite negative margins and repeated excisions, VC lesions recur and invade local tissues to the extent that only amputation of the involved foot has resulted in cure.

Implementing an integrated diabetic foot care programme in Ireland: podiatrists' experience.

BACKGROUND: International evidence suggests that an integrated multidisciplinary approach to diabetic foot management is necessary to prevent ulceration and progression to amputation. Many health systems have introduced policies or models of care supporting the introduction of this evidence into practice, but little is known about the experiences of those involved in implementation. This study addresses this gap by examining the experiences of podiatrists providing integrated diabetic foot care. METHODS: Between October 2017 and April 2018, an online survey comprising closed and open-ended questions on podiatrists' demographics, clinical activity, links with other services, continuous professional development activities and experiences of implementing the Model of Care was administered to podiatrists (n = 73) working for Ireland's Health Service Executive in the community and hospital setting. Data were analysed using descriptive statistics and qualitative content analysis. RESULTS: The response rate was 68% (n = 50), with 46% (n = 23), 38% (n = 19) and 16% (n = 8) working across hospital, community and both settings, respectively. Most reported treating high-risk patients (66%), those with active foot disease (61%) and educating people about the risk of diabetes to the lower limb (80%). Reported challenges towards integrated diabetic foot care include a perceived lack of awareness of the role of podiatry amongst other healthcare professionals, poor integration between hospital and community podiatry services, especially where new services had been developed, and insufficient number of podiatrists to meet service demands. CONCLUSION: Previous evidence has shown that there is often a gap between what is set out by a policy and what it looks like when delivered to service users. Results from the current study support this, highlighting that while most podiatrists work in line with national recommendations, there are specific gaps and challenges that need to be addressed to ensure successful policy implementation.

Persistence of orthopaedic hoof blocks for the treatment of lame cattle kept permanently at pasture.

AIMS: To compare the retention by New Zealand dairy cows kept at pasture in a lame cow group, of three hoof block products commonly used in the remediation of lameness. METHODS: Sixty-seven farmer-presented Friesian and Friesian x Jersey dairy cows from a single herd in the Manawatu region (New Zealand) suffering from unilateral hind limb lameness attributable to a claw horn lesion (CHL) were randomly allocated to one of three treatments: foam block (FB), plastic shoe (PS) and a standard wooden block (WB). Blocks were applied to the contralateral healthy claw and checked daily by the farm staff (present/not present) and date of loss was recorded. Blocks were reassessed on Day 14 and Day 28 and then removed unless further elevation was indicated. Daily walking distances were calculated using a farm map and measurement software. Statistical analyses included a linear marginal model for distance walked until block loss and a Cox regression model for the relative hazard of a block being lost. RESULTS: Random allocation meant that differences between products in proportion used on left or right hind foot or lateral or medial claw were small. Mean distance walked/cow/day on farm tracks whilst the block was present was 0.32 (min 0.12, max 0.45) km/day; no biologically important difference between products in the mean distance walked was identified. Compared to PS, cows in the WB group were five times more likely to lose the block (HR = 4.8 (95% CI = 1.8-12.4)), while cows in the FB group were 9.5 times more likely to lose the block (HR = 9.5 (95% CI = 3.6-24.4)). CONCLUSIONS: In this study, PS were retained for much longer than either FB or WB. As cows were managed in a lame cow group for the study duration, walking distances were low and did not impact on the risk of block loss. More data are needed to define ideal block retention time. CLINICAL RELEVANCE: In cows with CHL the choice of block could be based on the type of lesion present and the expected re-epithelisation times.

Patient-reported functional outcomes in a cohort of hand and foot sarcoma survivors treated with limb sparing surgery and radiation therapy.

BACKGROUND AND OBJECTIVES: Describe patient-reported functional outcomes for hand and foot sarcoma survivors treated with limb-sparing surgery and radiation therapy (LSS + RT). METHODS: Fifty-four patients with hand/wrist and foot/ankle sarcomas treated with LSS + RT from 1991 to 2015 were identified. Survivors ≥18 years old without subsequent amputation completed self-assessed functional surveys: Toronto upper extremity salvage score (TESS-UE) and Michigan hand outcomes (MHQ) surveys for hand; TESS lower extremity (TESS-LE) and Foot and Ankle Outcomes (FAOS) surveys for foot. Scoring scales: 0-100, MHQ and TESS; -26 to 56 and 25-59, FAOS core and shoe comfort, respectively. Higher scores denote superior function. RESULTS: Five-year local tumor control was 88%. Fourteen of 24 hand (58%) and 14/18 foot (78%) survivors completed surveys. Mean TESS-UE and MHQ scores were 89.4 and 72.8, respectively. Mean TESS-LE, core FAOS, and shoe comfort scores were 92.4, 46.19, and 53.1, respectively. No factors correlated with outcomes. TESS-UE and MHQ scores strongly correlated (r = .87). TESS-LE and FAOS scores were associated with a poor correlation (r = .02 and r = .69). CONCLUSIONS: The largest patient-reported functional outcomes analysis for hand and foot sarcoma survivors treated with LSS + RT demonstrates excellent local tumor control and acceptable functional outcomes. Further exploration of optimal functional assessment tools is needed given the potential scope differences.

The Equine Hoof: Laminitis, Progenitor (Stem) Cells, and Therapy Development.

The equine hoof capsule, composed of modified epidermis and dermis, is vital for protecting the third phalanx from forces of locomotion. There are descriptions of laminitis, defined as inflammation of sensitive hoof tissues but recognized as pathologic changes with or without inflammatory mediators, in the earliest records of domesticated horses. Laminitis can range from mild to serious, and signs can be acute, chronic, or transition from acute, severe inflammation to permanently abnormal tissue. Damage within the intricate dermal and epidermal connections of the primary and secondary lamellae is often associated with lifelong changes in hoof growth, repair, and conformation. Decades of research contribute to contemporary standards of care that include systemic and local therapies as well as mechanical hoof support. Despite this, consistent mechanisms to restore healthy tissue formation following a laminitic insult are lacking. Endogenous and exogenous progenitor cell contributions to healthy tissue formation is established for most tissues. There is comparably little information about equine hoof progenitor cells. Equine hoof anatomy, laminitis, and progenitor cells are covered in this review. The potential of progenitor cells to advance in vitro equine hoof tissue models and translate to clinical therapies may significantly improve prevention and treatment of a devastating condition that has afflicted equine companions throughout history.

Short communication: Claw block application improves locomotion and weight-bearing characteristics in cattle with foot diseases.

In cattle with foot diseases, application of a block on the healthy partner claw is a common method of pain relief. The aim of this study was to evaluate the effect of wooden claw blocks on locomotion characteristics and weight distribution in healthy (group C; n = 17) versus lame (group L; n = 17) cattle. Group L was further subdivided into group L1 (lameness score ≤3; n = 7) and group L2 (lameness score >3; n = 10). We performed lameness scoring using a numeric rating system and measured locomotion characteristics using 2 accelerometers (400 Hz; kinematic outcome = stance phase duration; kinetic outcomes = foot load and toe-off) and a 4-scale weighing platform (difference of mean weight distribution across the limbs; ∆weight) before and after application of a claw block. We applied claw blocks to a randomly assigned lateral or medial claw of the fore or hindlimb in group C cows, and on the healthy partner claw in group L cows. Variables were expressed as differences across limbs. We used 1-way ANOVA to determine the differences between groups C and L and between groups L1 and L2 for ∆weight after application of the claw block. We performed paired t tests to compare variables before and after application of the claw block in groups C and L. Group L scored higher on the numeric rating system than group C (mean ± SD, 3.40 ± 0.62 vs. 1.87 ± 0.28) and showed greater differences in relative stance phase duration (16.34 ± 10.78% vs. 2.13 ± 1.94%), foot load (9.68 ± 8.06 g vs. 3.26 ± 3.69 g), toe-off (3.91 ± 3.14 g vs. 0.78 ± 0.66 g), and ∆weight (53.62 ± 28.85% vs. 8.52 ± 6.19%). In group C, we observed an increase of 12.17 percentage points in ∆weight after block application, from 8.52 ± 6.19% to 20.69 ± 17.01%. Compared with the baseline, group L showed a decrease in numeric rating system score (2.88 ± 0.49 vs. 3.40 ± 0.62) and a decrease in differences between the limbs in relative stance phase duration (7.66 ± 9.96% vs. 16.34 ± 10.78%) and foot load (4.26 ± 4.14 g vs. 9.68 ± 8.06 g) after application of a claw block. Group L2 showed smaller ∆weight after application of a claw block than group L1 (-7.8 ± 8.7% vs. 10.4 ± 7.6%). After block application in group L, we observed smaller differences across the limbs in variables measured to describe gait-cycle characteristics while walking, but no significant improvement while standing. We concluded that application of a claw block must be combined with other methods of pain relief, such as analgesic medication.

The equine navicular apparatus as a premier enthesis organ: Functional implications.

Navicular syndrome has been traditionally characterized by progressive lameness with chronic degeneration of the navicular bone. Advances in imaging techniques have revealed that its associated soft tissue structures are also affected. This distribution of lesions is explained by conceptualizing the equine navicular apparatus as an enthesis organ that facilitates the dissemination of mechanical stress throughout the tissues of the foot. The navicular apparatus has the same structural adaptations to mechanical stress as the human Achilles tendon complex. These adaptations efficiently dissipate mechanical force away from the tendon's bony attachment site, thereby protecting it from failure. The comparison of these two anatomically distinct structural systems demonstrates their similar adaptations to mechanical forces, and illustrates that important functional insights can be gained from studying anatomic convergences and cross-species comparisons of function. Such a functional conceptualization of the equine navicular apparatus resolves confusion about the diagnosis of navicular syndrome and offers insights for the development of mechanically based therapies. Through comparison with the human Achilles complex, this review (1) re-conceptualizes the equine navicular apparatus as an enthesis organ in which mechanical forces are distributed throughout the structures of the organ; (2) describes the relationship between failure of the navicular enthesis organ and lesions of navicular syndrome; (3) considers the therapeutic implications of navicular enthesis organ degeneration as a form of chronic osteoarthritis; and based upon these implications (4) proposes a focus on whole body posture/motion for the development of prehabilitative and rehabilitative therapies similar to those that have already proven effective in humans.

Cryotherapy Techniques: Best Protocols to Support the Foot in Health and Disease.

Treatment of equine laminitis continues to be a challenge despite recent advancements in knowledge of the pathophysiology of laminitis. With more evidence supporting its use, distal limb hypothermia or cryotherapy has become a standard of care for both prevention of laminitis and treatment of the early stages of acute laminitis. Recent studies have demonstrated that cryotherapy reduces the severity of sepsis-related laminitis and hyperinsulinemic laminitis in experimental models and reduces the incidence of laminitis in clinical colitis cases. This article reviews the recent literature supporting the use of distal limb cryotherapy in horses.

Mechanical Principles of the Equine Foot.

A healthy foot requires a well-balanced foot capable of shock absorption, traction, and normal proprioception. Radiographs and venograms are helpful in assessing health of the external and internal structures of the foot and in early diagnosis. Other techniques to assess foot mechanics include force plate and inertial sensors. When foot pathology ensues, early recognition and emergency mechanical treatment can improve prognosis and overall outcome. Sheared heels, under-run heels, and clubfeet are common problems that need to be corrected early. Successful management and results require he veterinarians and farriers establishing a professional, collaborative, and respectful relationship.

Orthopedic Infections-Clinical Applications of Intravenous Regional Limb Perfusion in the Field.

For the equine veterinarian, orthopedic emergencies are a common occurrence in clinical practice, with traumatic wounds of the distal limb and penetrating injuries of the hoof being some of the most common medical conditions to affect horses. Intravenous regional limb perfusion is a technique widely used for the treatment of orthopedic infections in horses. The objectives of this review are to discuss some of the clinical applications for this treatment modality in the field and to review the technique for the practitioner.

Laminitis Updates: Sepsis/Systemic Inflammatory Response Syndrome-Associated Laminitis.

Sepsis or systemic inflammatory response syndrome (SIRS) -associated laminitis is a sequela to primary inflammatory conditions (eg, colitis, ischemic intestinal injury, pneumonia, metritis) and results from a dysregulated systemic inflammatory response that ultimately affects the digital lamellae. Local chemokine production, leukocyte migration, and proinflammatory mediator production occur within the lamellae that can lead to catastrophic lamellar failure. Controlling the primary disease, providing supportive care and anti-inflammatory therapy, applying digital cryotherapy, and providing mechanical support are cornerstones to the prevention of sepsis/SIRS-associated laminitis. Novel therapies targeting specific signaling pathways may provide additional therapeutic options in the future.

Effect of heel elevation on breakover phase in horses with laminitis.

BACKGROUND: In a laminitic horse, the maximal loading of the toe region occurs during the breakover phase. To date, no kinetic data demonstrates the effect of supportive orthopaedic therapy in horses with laminitis on breakover phase. Thus, the purpose of this study was to examine the effect of heel elevation on the breakover phase. Eight horses with acute laminitis treated medically as well as with application of a hoof cast with heel wedge (HCHW) were included in this study. Immediately following cessation of clinical signs of acute laminitis, two measurements using the Hoof™ System were taken: the first with HCHW and the second immediately following removal of the HCHW, i.e. in barefoot condition (BFC). The hoof print was divided into three regions: toe, middle hoof, and heel. Kinetic parameters included vertical force (VF), stance duration, contact area (CA) for all hoof regions during stance phase, duration of breakover, VF in the toe region at onset of breakover and location of centre of force. RESULTS: The VF and CA were higher in the heel region (63 and 61%, respectively) and decreased significantly after removal of the HCHW (43 and 28% after removal, respectively). The breakover phase in horses with HCHW lasted 2% of stance phase and was significantly shorter than that in BFC, which lasted 6% of stance phase. The VF at onset of breakover for the toe region in horses with HCHW was significantly lower than that in BFC. The centre of the force was located at the heel region in all horses with the HCHW, and at the middle the hoof region in BFC. CONCLUSIONS: Heel elevation in horses with laminitis as examined on a concrete surface significantly shortens breakover phase and decreases the vertical force in the toe region during breakover. HCHW provides adequate support to the palmar hoof structures by increasing the contact area in the heel region and incorporating the palmar part of frog and sole into weight bearing, thus decreasing the stress on the lamellae. Hoof cast with heel elevation could be a beneficial orthopaedic supportive therapy for horses suffering from acute laminitis.

Intraosseous epidermoid cysts of adjacent digits in a dog.

BACKGROUND: Intraosseous epidermoid cyst (IEC) is a rare, non-neoplastic, pathology in animals and humans that most commonly affects the distal phalanx. In dogs, it is important to differentiate this lesion from malignant digital tumours causing bone lysis. In previous reports, IEC has been described to affect only a single digit at the time of diagnosis which is usually based on histopathology. This is the first case report to describe immunohistochemically confirmed IECs affecting simultaneously multiple digits. CASE PRESENTATION: A 4-and-a-half-year-old female spayed Great Dane was presented with a 2-month history of progressive swelling of the distal phalanx (PIII) of digits IV and V of the right pelvic limb. Eleven weeks prior to presentation, the dog had a low-grade cutaneous mast cell tumour completely excised from the craniolateral base of its left pinna. A history of trauma to 1 of the nails of the same pes 4 years prior to referral was also reported. Examination of the right pelvic limb identified firm non-painful swelling of PIII of digits IV and V, with concurrent deformation of the nails. Radiographs of the right pes obtained by the primary veterinarian identified an expansile lesion of PIII of digits IV and V. Computed tomography identified large expansile lesions of PIII of digits IV and V, with associated cortical thinning and soft tissue swelling. Neoplasia was considered the most likely radiographic diagnosis. Histopathology of Jamshidi bone biopsies was consistent with intraosseous epidermoid cyst, which was confirmed with immunohistochemistry. Amputation of PIII of digits IV and V at the level of mid-PII was performed as definitive treatment. No recurrence of the lesion occurred during the 10-month follow-up period. CONCLUSIONS: Intraosseous epidermoid cysts should be included in the differential diagnosis for expansile lesions affecting the canine digit. It is important to differentiate them from other digital lesions, with bone involvement, such as malignant digital tumours, which often require more extensive surgery for definitive treatment. The case herein highlights that this lesion can affect simultaneously multiple digits. Definitive diagnosis can be achieved by identification of keratin-producing epithelial cells on histopathology and confirmed by pancytokeratin labelling.

Madurella mycetomatis infection of the foot: a case report of a neglected tropical disease in a non-endemic region.

BACKGROUND: Mycetoma is an uncommon chronic granulomatous infection of cutaneous and subcutaneous tissues that can be caused by filamentous bacteria (actinomycetoma) or fungi (eumycetoma). It is the prerogative of young men between the third and fourth decade and is transmitted through any trauma causing an inoculating point. The classic clinical triad associates a painless hard and swelling subcutaneous mass, multiple fistulas, and the pathognomonic discharge of grains. Although endemic in many tropical and subtropical countries, mycetoma can also be found in non-endemic areas as in Morocco, and causes then diagnosis problems leading to long lasting complications. Therefore, we should raise awareness of this neglected disease for an earlier management. Under medical treatment however, mycetoma has a slow healing and surgery is often needed, and relapses are possible. CASE PRESENTATION: Herein we report a case of a 64 years old patient, with a history of eumycetoma occurring ten years ago treated with oral terbinafine coupled with surgery. A complete remission was seen after 2 years. He presented a relapse on the previous scar 6 months ago. There wasn't any bone involvement in the magnetic resonance imaging (MRI). The patient was put under oral terbinafine with a slow but positive outcome. CONCLUSION: Through this case report, we perform a literature review and highlight the importance of increase awareness of mycetoma in clinical practice especially in non-endemic regions.

Short communication: Anesthetic residues in milk after topical application during treatment of hoof lesions in dairy cows.

Hoof lesions in dairy cows are usually treated by trimming the hoof. However, trimming by itself can cause severe pain or exacerbate already existing pain. Hoof trimming is usually not carried out by trained veterinarians, and pain management is not provided. Pain control during trimming is not only an ethical obligation but also allows for better manipulation and more meticulous treatment. Tri-Solfen (Bayer Animal Health, Pymble, Australia) is a spray gel containing lidocaine, bupivacaine, and cetrimide that is easily applied topically and has demonstrated pain-mitigation effects during and after hoof trimming. In the European Union, these local anesthetics are not approved for use in food-producing animals because of a lack of residue data and concerns about genotoxic effects in cattle and humans. The aim of this study was to assess lidocaine, bupivacaine, and 2,6-xylidine residues in milk after Tri-Solfen application in dairy cows. Five dairy cattle in the dry-off period were enrolled in the study based on clinical evidence of lameness (score ≥3 on a 5-point scale). After cleaning and superficial trimming, we applied 3 to 14 mL of Tri-Solfen to the lesions before continuing treatment. Two milk samples were collected per animal in the following 4 milkings and analyzed in a reference laboratory. Residues of lidocaine above the limits of quantification (0.2 µg/L) were found in milk samples in the first milking 6 h after treatment in only 2 cows. This study shows that excretion of local anesthetics and their metabolites in milk after topical application of Tri-Solfen is negligible and even undetectable after the first milking 6 h post-treatment.

Management of Knuckling in an Ostrich (Struthio camelus) Using a Custom-Made Orthotic Shoe.

A 4-year-old female ostrich (Struthio camelus) developed knuckling on its left foot after a traumatic event. Conservative treatment, rest, and traditional splinting methods failed to resolve the gait abnormality or improve mobility. A dynamic multicomponent orthotic shoe was then custom designed and fabricated with an ultra-high-molecular weight, low-pressure polyethylene polymer (St 1000 DIN16972 TG2) to correct the foot malposition. The affected foot and leg were wrapped with soft padding and the orthosis was attached and secured by nylon belts (Nylon PA [polyamide] 6, a semicrystalline polyamide polymer) with self-locking modified wrench straps. The orthosis immediately prevented knuckling and improved ambulation. After 2 weeks, this shoe was replaced with a modified orthotic shoe of lighter weight to improve kinetics and ease of use by the bird. The modified orthosis dramatically improved ambulation and was left attached to the affected leg for 7 more weeks. Thereafter, the bird was able to ambulate comfortably without the aid of the shoe, even though permanent anatomical changes to the affected leg seemed to restrict its speed of locomotion. The ostrich had another unfortunate traumatic event 10 weeks later, the result of which was knuckling on the contralateral (right) foot. After routine medical and supportive care, the orthosis was then applied to the right foot for a period of 9 weeks. During this period the bird was able to ambulate well, despite having to support the bulk of its weight on the previously affected left limb. At the end of 9 weeks, the orthosis was removed, and the bird was able to ambulate without aid, although the bird's speed of locomotion was considerably reduced. After recovery of its leg problems, the ostrich was confined to a relatively small paddock for the rest of its life.

Podiatry interventions to prevent falls in older people: a systematic review and meta-analysis.

BACKGROUND: foot problems are independent risk factors for falls in older people. Podiatrists diagnose and treat a wide range of problems affecting the feet, ankles and lower limbs. However, the effectiveness of podiatry interventions to prevent falls in older people is unknown. This systematic review examined podiatry interventions for falls prevention delivered in the community and in care homes. METHODS: systematic review and meta-analysis. We searched multiple electronic databases with no language restrictions. Randomised or quasi-randomised-controlled trials documenting podiatry interventions in older people (aged 60+) were included. Two reviewers independently applied selection criteria and assessed methodological quality using the Cochrane Risk of Bias tool. TiDieR guidelines guided data extraction and where suitable statistical summary data were available, we combined the selected outcome data in pooled meta-analyses. RESULTS: from 35,857 titles and 5,201 screened abstracts, nine studies involving 6,502 participants (range 40-3,727) met the inclusion criteria. Interventions were single component podiatry (two studies), multifaceted podiatry (three studies), or multifactorial involving other components and referral to podiatry component (four studies). Seven studies were conducted in the community and two in care homes. Quality assessment showed overall low risk for selection bias, but unclear or high risk of detection bias in 4/9 studies. Combining falls rate data showed significant effects for multifaceted podiatry interventions compared to usual care (falls rate ratio 0.77 [95% CI 0.61, 0.99]); and multifactorial interventions including podiatry (falls rate ratio: 0.73 [95% CI 0.54, 0.98]). Single component podiatry interventions demonstrated no significant effects on falls rate. CONCLUSIONS: multifaceted podiatry interventions and multifactorial interventions involving referral to podiatry produce significant reductions in falls rate. The effect of multi-component podiatry interventions and of podiatry within multifactorial interventions in care homes is unknown and requires further trial data.

A Systematic Review of Radiofrequency Treatment of the Ankle for the Management of Chronic Foot and Ankle Pain.

BACKGROUND: Chronic pain of the lower extremity remains challenging to manage. Radiofrequency treatment applies heat to nerve fibers with the goal of mitigating chronic pain conditions. The clinical efficacy has not yet been adequately established for pathologies of the ankle and foot. In this review paper, we report the use and efficacy of radiofrequency treatment applied to foot and ankle pain. RECENT FINDINGS: PubMed and the Cochrane Controlled Trials Register were searched (final search 30 March 2018) using the MeSH terms "radiofrequency ablation," "neurolysis," "radiofrequency therapy," "pain syndrome," "analgesia," "plantar heel pain," "plantar fascitis," and "chronic pain" in the English literature. Of the 23 papers screened, 18 were further investigated for relevance. Our final search methodology yielded 15 studies that investigated the use of radiofrequency treatment at the ankle. Of these 15 studies, there were three randomized control trials, four prospective studies, three retrospective studies, and five case reports. The quality of selected publications was assessed using the Cochrane risk of bias instrument. The evidence from our studies suggests that radiofrequency treatment can be used safely for the management foot and ankle pain. The technique (continuous vs pulsatile), temperature, location of treatment, and duration of administration need more thorough evaluation. Randomized control trials are needed to establish the efficacy and safety profile of radiofrequency ablation and its long-term benefits in patients with chronic pain of the foot and ankle. CONCLUSION: The evidence from our studies suggests that radiofrequency treatment can be used safely for the management foot and ankle pain. The technique (continuous vs pulsatile), temperature, location of treatment, and duration of administration need more thorough evaluation. Randomized control trials are needed to establish the efficacy and safety profile of radiofrequency ablation and its long-term benefits in patients with chronic pain of the foot and ankle.

Health professional views on the assessment and management of foot problems in people with psoriatic arthritis in Australia and New Zealand: a qualitative investigation.

BACKGROUND: Active foot disease persists in a high proportion of people with psoriatic arthritis despite the availability of pharmacological and non-pharmacological interventions to modify the course of the disease. Limited information exists on the provision of health care for foot disease in psoriatic arthritis. The objective of this study was to explore the views of health professionals on the assessment and management of people with psoriatic arthritis-related foot involvement. METHODS: Convenience sampling was used to recruit health professionals working in rheumatology outpatient clinics in Sydney, Australia and Auckland, New Zealand. Three focus groups were undertaken to explore the views and experiences of health professionals on the assessment and management of foot problems in people with psoriatic arthritis. All interviews were audio-recorded and transcribed verbatim. Qualitative data was analysed using a constant comparative analytic approach to identify themes. RESULTS: A total of seventeen health professionals participated including rheumatologists, podiatrists and a physiotherapist. Key themes derived from the focus groups suggest that health professionals perceived that people with psoriatic arthritis-related foot problems experience suboptimal management from symptom onset, to diagnosis and treatment. Frustration was expressed throughout discussions relating to lack of appropriate training and expertise required for the specialised management of foot problems typically encountered with psoriatic arthritis and poor access for patients to specialist podiatry services. CONCLUSIONS: This study provides new insight into the perspectives of health professionals on the management of foot problems related to psoriatic arthritis. Deficiencies in the diagnosis, assessment and treatment of foot problems were revealed. To meet the foot health needs of people with psoriatic arthritis, reducing diagnostic delay, improving knowledge and awareness about the disease among people with psoriatic arthritis and health professionals, and increasing specialist podiatry service provision may be required.
