Radiotherapy for Ledderhose disease: Results of the LedRad-study, a prospective multicentre randomised double-blind phase 3 trial.

BACKGROUND AND PURPOSE: Radiotherapy is considered a treatment option for Ledderhose disease. However, its benefits have never been confirmed in a randomised controlled trial. Therefore, the LedRad-study was conducted. MATERIALS AND METHODS: The LedRad-study is a prospective multicentre randomised double-blind phase three trial. Patients were randomised to sham-radiotherapy (placebo) or radiotherapy. The primary endpoint was pain reduction at 12 months after treatment, measured with the Numeric Rating Scale (NRS). Secondary endpoints were pain reduction at 6 and 18 months after treatment, quality of life (QoL), walking abilities and toxicity. RESULTS: A total of 84 patients were enrolled. At 12 and 18 months, patients in the radiotherapy group had a lower mean pain score compared to patients in the sham-radiotherapy group (2.5 versus 3.6 (p = 0.03) and 2.1 versus 3.4 (p = 0.008), respectively). Pain relief at 12 months was 74% in the radiotherapy group and 56% in the sham-radiotherapy group (p = 0.002). Multilevel testing for QoL scores showed higher QoL scores in the radiotherapy group compared to the sham-radiotherapy group (p < 0.001). Moreover, patients in the radiotherapy group had a higher mean walking speed and step rate with barefoot speed walking (p = 0.02). Erythema, skin dryness, burning sensations and increased pain were the most frequently reported side effects. These side effects were generally graded as mild (95%) and the majority (87%) were resolved at 18 months follow-up. CONCLUSION: Radiotherapy for symptomatic Ledderhose disease is an effective treatment resulting in a significant pain reduction, improvement of QoL scores and bare feet walking abilities, in comparison to sham-radiotherapy.

Effect of painful Ledderhose disease on dynamic plantar foot pressure distribution during walking: a case-control study.

BACKGROUND: Plantar pressure distribution during walking in patients with painful Ledderhose disease is unknown. RESEARCH QUESTION: Do patients with painful Ledderhose disease have an altered plantar pressure distribution during walking compared to individuals without foot pathologies? It was hypothesized that plantar pressure is shifted away from the painful nodules. METHODS: Pedobarography data of 41 patients with painful Ledderhose disease (cases, mean age: 54.2 ± 10.4 years) was collected and compared to pedobarography data from 41 individuals without foot pathologies (controls, mean age: 21.7 ± 2.0 years). Peak Pressure (PP), Maximum Mean Pressure (MMP) and Force-Time Integral (FTI) were calculated for eight regions (heel, medial midfoot, lateral midfoot, medial forefoot, central forefoot, lateral forefoot, hallux and other toes) under the soles of the feet. Differences between cases and controls were calculated and analysed by means of linear (mixed models) regression. RESULTS: Proportional differences in PP, MMP and FTI showed increased values for the cases compared to the controls, especially in the heel, hallux and other toes regions, and decreased values in the medial- and lateral midfoot regions. In naïve regression analysis, being a patient was a predictor for increased- and decreased values for PP, MMP and FTI for several regions. When dependencies in the data were taken into account with linear mixed-model regression analysis, the increased- and decreased values for the patients were most prevalent for FTI at the heel, medial midfoot, hallux and other toes regions. SIGNIFICANCE: In patients with painful Ledderhose disease, during walking, a shift of pressure was found towards the proximal and distal foot regions, while offloading the midfoot regions.

Radiotherapy for Plantar Fibromas (Ledderhose Disease).

Ledderhose disease (plantar fibromas) is histologically related to Dupuytren disease, which has been successfully treated for years with radiotherapy. Many conservative treatments have been advanced for plantar fibromas, including accommodative orthotic devices, which help but do not cure the disease. Surgery is considered the mainstay of treatment for this malady, but the failure rate has been as high as 100%, depending on the type of fasciectomy. Radiotherapy is a new, exciting modality that has shown promising results for treating plantar fibromas.

Sorafenib in Dupuytren and Ledderhose Disease.

Palmar and plantar fibromatosis are benign proliferative processes which present as a diffuse thickening or nodules of the hands and/or feet and may lead to flexion contractures, pain, and functional impairment known as Dupuytren and Ledderhose diseases, respectively. Current treatments are noncurative and associated with significant morbidity. Here, we report on the outcomes of 5 patients with advanced disease, no longer surgical candidates, treated with sorafenib. Sorafenib exhibited an expected safety profile. All 5 patients demonstrated objective responses as evaluated by a decrease in tumor size and/or tumor cellularity from baseline and all 5 patients reported subjective pain relief and/or functional improvement. Mechanistically, immunohistochemistry revealed patchy positivity for PDGFRß, a known target of sorafenib. The outcomes of these 5 patients suggest the safety and efficacy of a relatively well-tolerated oral agent in the treatment of Dupuytren and Ledderhose diseases and suggest the need for future controlled studies.

Radiotherapy for patients with Ledderhose disease: Long-term effects, side effects and patient-rated outcome.

BACKGROUND: The purpose of this study was to investigate the long-term effects of radiotherapy for patients with Ledderhose disease. METHODS: Questionnaires were sent to all patients with Ledderhose disease who had been treated with radiotherapy at our centre between 2008 and 2017 and who consented to participate. Radiotherapy was performed with orthovolt or electrons in two separate courses of five daily fractions of 3 Gy. The questionnaires addressed items such as pain from Ledderhose disease (Brief Pain Inventory), quality of life (EURO-QOL-5D-5L), long-term side effects, and patients' levels of satisfaction with the effect of treatment. Descriptive statistics and non-parametric tests were used to analyse the results. RESULTS: A total of 102 feet were irradiated in 67 patients (28 men, 39 women). Radiotherapy resulted in significant pain reduction: the mean pain score prior to radiotherapy, collected retrospectively, was 5.7 and 1.7 at time of assessment (p-value < 0.001). The following pain response scores were reported: progressive pain (0%), no change (22%; 22 feet), partial pain response (37%; 38 feet) and complete pain response (absence of pain) (41%; 42 feet). Seventy-eight percent of patients were satisfied with the treatment effect and 57% did not consider radiotherapy burdensome. The scores for societal perspective (0.856) and patients' perspective on quality of life (82.3) were each comparable to the reference values from the Dutch population in the same age category (0.857 and 80.6, respectively). The most commonly reported residual long-term side effect was dryness of the skin (n = 10; 15%). CONCLUSION: Radiotherapy for Ledderhose disease results in long-term pain reduction in the majority of patients and has limited side effects. The treatment is well tolerated, patients feel satisfied, and quality of life is comparable to the reference population.

Plantar fascial fibromatosis and herpes zoster.

PURPOSE: Infection, chronic pain and depression are considered risk factors for herpes zoster (HZ). However, the correlation between plantar fascial fibromatosis (PFF) and HZ remains unknown. This study investigated HZ risk in patients with PFF. METHODS: Data was extracted from the Longitudinal Health Insurance Database 2000, which is a subsample of the Taiwan National Health Insurance (NHI) Research Database and contains 1 million NHI beneficiaries. Between 2000 and 2012, patients diagnosed as having PFF were included in the case cohort. Every case was age and sex-matched with individuals without PFF through 1:4 frequency matching (control cohort). The end of the follow-up was defined as December 31, 2013, the date of HZ diagnosis, death, emigration, or withdrawal from the NHI program. RESULTS: In total, 4,729 patients were diagnosed as having PFF and were matched with 18,916 individuals without PFF. Patients with PFF were 1.23 times more likely to develop HZ than were those without PFF. Among those aged ≥65 years, patients with PFF had a higher HZ risk than did those without PFF (adjusted hazard ratio [aHR] = 1.48). Men with PFF had a significantly higher risk of HZ than did men without PFF (aHR = 1.44). CONCLUSION: Patients with PFF, particularly older and male patients, having a high HZ risk and may thus be vaccinated for HZ.

Patients with Dupuytren's Contracture, Ledderhose Disease, and Peyronie's Disease are at higher risk of arthrofibrosis following total knee arthroplasty.

BACKGROUND: Total knee arthroplasty (TKA) is a successful treatment for patients with late stage osteoarthritis, yet arthrofibrosis remains a consistent cause of TKA failure. Dupuytren's, Ledderhose and Peyronie's Diseases are related conditions of increased fibroblast proliferation. The aim of this study was to identify whether an association exists between these conditions and arthrofibrosis following TKA. METHODS: Patient records were queried from 2010 to 2016 using an administrative claims database to compare the rates of arthrofibrosis, manipulation under anesthesia (MUA), lysis of adhesions (LOA), and revision TKA in patients with independent chart diagnoses of Dupuytren's Contracture, Ledderhose, or Peyronie's Diseases versus those without. Complications were queried and compared using multivariate logistic regression. RESULTS: Patients with Dupuytren's (n = 5,232) and Ledderhose (n = 50,716) had a significantly higher rate of ankylosis following TKA: 30-days (OR, 1.54; OR, 1.23), 90-days (OR, 1.20; OR, 1.24), 6-months (OR, 1.23; OR, 1.23), and 1-year (OR, 1.28; OR, 1.23), while patients with Peyronie's (n = 1,186) had a higher rate of diagnosis at 6-months (OR, 1.37) and 1-year (OR, 1.35). Patients with diagnoses of any of the fibroproliferative diseases had a statistically higher risk of MUA at 90-days, 6-month, and 1-year following primary TKA. These cohorts did not have a significantly higher rate of revision TKA. CONCLUSION: There is an increased odds risk of arthrofibrosis and MUA in patients who have undergone TKA and have a diagnosis of Dupuytren's Contracture, Ledderhose, or Peyronie's Diseases. Improvements to frequency and application of post-operative treatment should be considered in these cohorts to improve outcomes.

Follow-up of clinical and sonographic features after extracorporeal shock wave therapy in painful plantar fibromatosis.

BACKGROUND: Extracorporeal shock wave therapy (ESWT) has been used as a safe alternative treatment for refractory musculoskeletal diseases, such as plantar fasciitis, Achilles tendinopathy and gluteal tendinopathy, and various forms of fibromatosis including palmar or penile fibromatosis. However, there is limited published data for clinical and sonographic features of plantar fibromatosis after ESWT. The purpose of this study was to evaluate the long-term clinical outcome of ESWT in ultrasonography-confirmed plantar fibromatosis and ultrasonographic changes of plantar fibroma after ESWT. METHODS: Medical charts of 26 patients (30 feet) with plantar fibromatosis confirmed by ultrasonography were reviewed. Finally, a total of 10 feet who underwent ESWT for "Poor" or "Fair" grade of Roles-Maudsley Score (RMS) and symptoms persisted for >6 months were included in this study. Short-term follow-up was conducted one week after ESWT and long-term follow-up time averaged 34.0 months. The Numerical Rating Scale (NRS) and RMS were collected for the evaluation of clinical features. Follow-up ultrasonography was conducted at long-term follow-up and changes of plantar fibroma was assessed. A greater than 50% reduction in the NRS and achievement of a "good" or "excellent" grade in the RMS were regarded as treatment success. Additionally, medical charts of 144 patients (168 feet) with plantar fasciitis confirmed by ultrasonography were reviewed and subsequently, 42 feet who underwent ESWT with the same protocol were included for the comparison of clinical features. RESULTS: In plantar fibromatosis, baseline NRS (6.2 ± 1.3) and RMS (3.5 ± 0.5) were significantly improved at short-term follow-up (NRS, 1.8 ± 1.0; RMS, 2.0 ± 0.8, P < .001, respectively) and long-term follow-up (NRS, 0.6 ± 1.1; RMS, 1.4 ± 0.8, P < .001, respectively). Treatment success was recorded in seven feet (70.0%) at short-term follow-up and 8 feet (80%) at long-term follow-up, which is comparable to that of the plantar fasciitis group (28 feet, 66.7%; 35 feet, 83.3%, respectively). In long-term follow-up ultrasonography, mean fibroma thickness was reduced from 4.4±1.0 to 2.6±0.8 mm (P = .003); however, length and width were not significantly changed. There were no serious adverse effects. CONCLUSION: While these are preliminary findings, and must be confirmed in a randomized placebo control study, ESWT can have a beneficial long-term effect on pain relief and functional outcomes in painful plantar fibromatosis. However, ESWT is unlikely to affect the ultrasonographic morphology of plantar fibroma, with the exception of reducing the thickness. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

Prevalence of Peyronie and Ledderhose Diseases in a Series of 730 Patients with Dupuytren Disease.

BACKGROUND: Dupuytren, Peyronie, and Ledderhose diseases are related fibroproliferative disorders characterized by abnormalities in the connective tissue of the palm of the hand, the tunica albuginea of the penis, and the sole of the foot, respectively. Concomitant prevalence rates of these diseases have only been described in a few small populations. This article aims to report on a large population and to raise awareness in surgeons treating Dupuytren disease for concurring related fibroproliferative disorders. METHODS: Patients diagnosed as having Dupuytren disease were recruited from outpatient clinics in the northern part of the Netherlands from 2007 to 2016. Questionnaires concerning demographics, clinical characteristics, the coexistence of Ledderhose and/or Peyronie diseases, and other factors were filled in by the participants and by plastic surgeons. RESULTS: For 730 men with Dupuytren disease, the surgeons' reported prevalence rate of Peyronie disease was 7.8 percent and of Ledderhose disease was 16.1 percent. The participants themselves reported prevalence rates of 8.8 percent for Peyronie disease and of 22.0 percent for Ledderhose disease. CONCLUSIONS: In the Dupuytren patient cohort, the prevalence of Peyronie disease was lower than that described in the literature. The prevalence of Ledderhose disease corresponded with the rates from the literature. However, both were underreported by plastic surgeons, which calls for a rise in awareness, recognition, and referral to a urologist when the conditions are bothersome or symptomatic.

The Effects of Collagenase Clostridium histolyticum on Plantar Fibromatosis: A Case Study.

Plantar fibromatosis, also known as Ledderhose's disease, is a rare disorder of benign fibroblast proliferation involving the plantar aponeurosis (i.e., plantar fascia). Traditionally, surgical intervention has been the most common treatment for plantar fibromatosis. However, numerous studies have reported high recurrence rates of plantar fibromatosis after surgical intervention, as well as wound healing difficulties and nerve injury. Plantar fibromatosis often coexists with other superficial fibrous diseases such as Dupuytren's contracture and Peyronie's disease; immunohistochemical and ultrastructural analyses suggest a relationship between Ledderhose's disease and Dupuytren's contracture. The US Food and Drug Administration approved collagenase Clostridium histolyticum for the treatment of Dupuytren's contracture in 2010 and Peyronie's disease in 2013. This case study presents the successful treatment of Ledderhose's disease almost 4 years (45.5 months) after off-label use of collagenase C. histolyticum injection in a 22-year-old white female who had recurrent plantar fibromatosis after surgical intervention.

Dupuytren, Ledderhose, and Peyronie Diseases After Primidone Use For Essential Tremor.

INTRODUCTION: Dupuytren, Ledderhose, and Peyronie diseases are chronic fibrotic conditions related to progressive fibrosis of the palmar fascia, plantar fascia, and tunica albuginea, respectively. These conditions have been associated with antiepileptic drug use, mainly phenobarbital and primidone. CASE REPORT: A 71-year-old man developed simultaneous Dupuytren, Ledderhose, and Peyronie diseases after primidone use for essential tremor. CONCLUSIONS: There are a few reports associating barbiturate use to connective tissue disorders, and some suggest that drug withdrawal may result in a better prognosis. Therefore, physicians must be aware of such adverse events when caring for patients on long-term barbiturate use.

Bilateral Plantar Fibromatosis

Aim To describe an uncommon clinical finding and raise awareness of its manifestation and associated conditions. Methods This case describes a gentleman with bilateral plantar fibromatosis caused by type 2 Diabetes Mellitus and previous alcohol excess. Results Treatment options include physiotherapy, steroid and collagenase injection therapy. Surgical intervention can be considered for persistently symptomatic or recurrent cases. Discussion In conclusion, plantar fibromatosis is an under-recognised and disabling condition which should prompt intervention and optimisation of co-morbidities.

Clinics in diagnostic imaging (195). Plantar fibromatosis.

A 46-year-old man presented with a six-month history of lumps in the sole of his left foot. Physical examination revealed two nodules, one tender and one firm, at the plantar left foot with no overlying skin changes. Although the initial radiographs were normal, magnetic resonance imaging of the left foot demonstrated two nodules along the medial band of the plantar fascia, characteristic of plantar fibromas. The patient opted for surgical excision. There was no further recurrence of symptoms after surgery. We describe the clinical and radiological features of plantar fibromatosis and briefly discuss other causes of lumps and pain in the sole of the foot.

Clinical features and management of superficial fibromatoses.

Fibromatoses are a group of benign connective tissue tumors characterized by the infiltrative, aggressive proliferation of well-differentiated fibroblasts, leading to frequent local recurrence. Within this heterogeneous disease group, superficial fibromatoses show slower growth and more benign infiltration of surrounding tissues than deep fibromatoses. Superficial fibromatoses relevant to dermatology include palmar, plantar, and penile fibromatosis, knuckle pads, pachydermodactyly and infantile digital fibromatosis. They present clinically with subcutaneous nodules or cords that lead to local infiltration and limited mobility of the affected areas. Treatment options vary from watchful waiting, non-invasive methods such as radiotherapy and intralesional corticosteroid/collagenase injections to radical surgical procedures. Early intervention may disrupt disease progression and may even restore functional ability. These disorders should therefore be recognized and treated early in the course of the disease.

Current concepts about treatment options of plantar fibromatosis: A systematic review of the literature.

BACKGROUND: Plantar fibromatosis, or Ledderhose disease, is a benign and hyperproliferative disease of the plantar aponeurosis. There have been described different therapeutic options regarding plantar fibromatosis, both conservative and surgical. The aim of this review is to systematically analyze conservative and operative treatments of plantar fibromatosis described in literature, evaluating which procedure shows the highest success rate and best functional outcome. METHODS: A systematic review of PubMed, Google Scholar and Cochrane reviews computerized database was performed focusing on the different types of treatments for plantar fibromatosis. Research was performed using the keywords "plantar", "fibromatosis", "Ledderhose", "Dupuytren", "foot" in order to identify all papers regarding the treatment of plantar fibromatosis. In addition, the research was extended to the reference list of the relevant articles. A total of 25 citations were obtained from the research and included. RESULTS: Considering all the studies, 233 patients were included in this systematic review. 5 studies reported conservative treatment of plantar fibromatosis, with a total of 35 patients included. Operative outcomes are reported for 178 patients (92 male, 86 female), with 196 feet treated. CONCLUSIONS: Valid conservative methods are presented in literature, with debated results. Some operative options show high recurrence rate; wide excision is recommended in selected cases. Further clinical trials with well-defined and standardized outcome measurements should be necessary in future to better evaluate success rate and complications of the various procedures.

Clinical, histological and therapeutic modern approach of Ledderhose disease.

Ledderhose disease or plantar fibromatosis is a rare hyperproliferative disorder of the plantar aponeurosis, clinically characterized by nodules situated especially on the medial border of the foot. It is histopathologically associated with Dupuytren's disease. This disease has some risk factors, like old age, alcohol or nicotine abuse, liver dysfunction, trauma or exposure to vibrations and autoimmune disorders, but the exact etiology is still unknown. Even though it is benign, the local manifestations can be aggressive, leading to debilitating deformities and contractures of the toes. Ultrasound and magnetic resonance imaging are used to confirm the diagnosis and to eliminate other disorders. Whenever is possible, the conservative therapies are recommended. Having a high recurrence, Ledderhose disease can be hard to treat, needing multiple surgical interventions. This paper aims to cover all the important aspects of this disease for daily medical practice, from history to clinical manifestations, diagnostic methods and histopathological features, to conservative and surgical treatment modalities.
