RESUMEN
Tumoral calcinosis is a rare disorder defined as the development of periarticular calcified masses, typically surrounding large joints, although they may occur in the foot. We present a case of a patient with systemic tumoral calcinosis with lesions in both shoulders and wrists and a relatively large lesion in the right foot presenting with foot pain.

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.

CASE: Bizarre parosteal osteocartilaginous proliferation (BPOP) is rare, especially in the foot. To the best of our knowledge, multifocal BPOP has yet to be reported. We are reporting a case of a 40-year-old woman who presented with 4 bumps over her midfoot and toes. After staging studies, we excised the lesions, and histopathology confirmed BPOP. No local recurrence was observed at the end of the 2-year follow-up. CONCLUSION: BPOP should be considered in the differential diagnosis of multiple foot bumps, whether synchronous or metachronous, which may present multifocally in the foot.

BACKGROUND: Angioleiomyoma is a benign soft-tissue tumor that arises from the smooth muscle cells in the tunica media of the blood vessels. Although the most common location for these neoplasms is the uterine wall, they can also originate from lower limbs. Altogether, these neoplasms account for 0.2% of all those located in the foot and ankle region. Signs and symptoms of foot angioleiomyoma can be a localized pain, swelling, and functional impairment. To date, only case reports and case series with small populations have been reported in the literature to describe the clinical picture of these neoplasms and the effectiveness of surgical treatment. In this study, we report our results of surgical treatment for angioleiomyomas of the foot. METHODS: Thirteen cases suffering from angioleiomyoma of the foot underwent surgical resection in our institution between January of 2017 and January of 2022. For each case, we recorded preoperative and postoperative symptoms, and their preoperative and postoperative functional status according to both Musculoskeletal Tumor Society Score (MSTS) and American Orthopedic Foot and Ankle Society Score (AOFAS). Eventual complications and local recurrence were reported. RESULTS: Each patient had at least mild pain before surgical treatment. The mean preoperative MSTS and AOFAS were 22.1 and 76.8, respectively. The mean tumor size was 17.7mm. Preoperatively, each patient underwent resection with wide margins. None had local recurrences or major complications at their latest follow-up. After surgery, the mean postoperative MSTS and AOFAS increased to 29.5 and 98.8, respectively. Each case had a marked increment of their functionality and a reduction of their pain after surgery. CONCLUSIONS: Our results suggest that surgical approach with tumor resection should be considered a safe and reliable treatment for foot angioleiomyomas in light of the extremely low risk of local recurrence and because of the good postoperative pain relief and functional restoration that can be obtained after the treatment.

PURPOSE: This study aimed to calculate region and diagnosis-specific minimal important changes (MICs) of the Foot and Ankle Outcome Score (FAOS) and the Foot and Ankle Ability Measure (FAAM) in patients requiring foot and ankle surgery and to assess their variability across different foot and ankle diagnoses. METHODS: The study used routinely collected data from patients undergoing elective foot and ankle surgery. Patients had been invited to complete the FAOS and FAAM preoperatively and at 3-6 months after surgery, along with two anchor questions encompassing change in pain and daily function. Patients were categorised according to region of pathology and subsequent diagnoses. MICs were calculated using predictive modelling (MICPRED) and receiver operating characteristic curve (MICROC) method and evaluated according to strict credibility criteria. RESULTS: Substantial variability of the MICs between forefoot and ankle/hindfoot region was observed, as well as among specific foot and ankle diagnoses, with MICPRED and MICROC values ranging from 7.8 to 25.5 points and 9.4 to 27.8, respectively. Despite differences between MICROC and MICPRED estimates, both calculation methods exhibited largely consistent patterns of variation across subgroups, with forefoot conditions systematically showing smaller MICs than ankle/hindfoot conditions. Most MICs demonstrated high credibility; however, the majority of the MICs for the FAOS symptoms subscale and forefoot conditions exhibited insufficient or low credibility. CONCLUSION: The MICs of the FAOS and FAAM vary across foot and ankle diagnoses in patients undergoing elective foot and ankle surgery and should not be used as a universal fixed value, but recognised as contextual parameters. This can help clinicians and researchers in more accurate interpretation of the FAOS and FAAM change scores. LEVEL OF EVIDENCE: Level IV.

Verrucous carcinoma (VC) is a rare, low-grade variant of well-differentiated squamous cell carcinoma. Plantar verrucous carcinoma presents as a slow-growing, exophytic, verrucous plaque on weight bearing areas of the foot. Verrucous carcinomas have low metastatic potential, but are high risk for local invasion. We describe a patient with a 20-year history of a slowly growing, ulcerated, verrucous plaque on the sole of the left foot that was erroneously treated for years as verruca plantaris and was eventually diagnosed as invasive verrucous carcinoma. Verrucous carcinomas are a diagnostic challenge due to clinical and histopathologic mimicry of benign lesions. Mohs micrographic surgery should be employed to allow the ability to intraoperatively assess tumor margins while excising the minimal amount of necessary tissue. It is important for clinicians to recognize the characteristics and accurately diagnose verrucous carcinomas. Delays in treatment may require more extensive dissection or amputation.

INTRODUCTION: The foot is a complex structure composed of several tissues, each of which can be the origin of the proliferation and development of the tumour. Most lesions about the foot are reactive or inflammatory, but some are true neoplasms. METHOD: This is a retrospective analysis of 4997 patient records treated in the Orthopaedic Oncology Unit of University Malaya Medical Centre, Malaysia, between 1 January 2010 to 31 December 2020. Demographic data of 195 patients with foot tumours were analysed out of 4997 neoplasm patients. RESULTS: There were 195 cases of foot tumours: 148 were benign, and 47 were malignant. 47 were bone tumours, 4 were metastases, and 144 were soft tissue tumours. Six patients succumbed to the disease, two cases of giant cell tumour (GCT) and one patient with synovial sarcoma had a recurrence. Treatment of foot tumours was wide resection in general. However, in metastasis cases, amputation was done. The majority of tumours were in the toes and dorsum of the foot. Soft tissue tumours of the foot occur in the elderly population in contrast to bone tumours, mainly in the second decade of life. The gender distribution was almost equal for foot tumours. Ganglion and Giant Cell Tumour of the bone are the commonest benign soft tissue and bone tumours. The most common malignant soft tissue and bone tumours are malignant melanoma and chondrosarcoma. The amputation rate is 5.64% the recurrence rate is 1.54%. Mortality rate is 3.08%. The MSTS score is 79%, and the TESS score is 76.23%. CONCLUSION: Foot tumours are relatively rare, mostly originating from soft tissue and exhibiting a benign nature. Nonetheless, a noteworthy proportion-approximately a quarter of these tumours-demonstrate malignancy. The surgical interventions undertaken in managing these tumours and associated functional outcomes generally yield acceptable results.

Objective: To compare the effectiveness of talonavicular-cuneiform joint fusion with iliac bone grafting and without bone grafting in the treatment of Müller-Weiss diseases (MWD). Methods: The clinical data of 44 patients (44 feet) with MWD who received talonavicular-cuneiform joint fusion between January 2017 and November 2022 and met the selection criteria was retrospectively analyzed. Among them, 25 patients were treated with structural iliac bone grafting (bone grafting group) and 19 patients without bone grafting (non-bone grafting group). There was no significant difference ( P>0.05) in age, gender composition, body mass index, disease duration, affected side, Maceira stage, and preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) score, anteroposterior/lateral Meary angle, and Pitch angle between the two groups. Operation time, operation cost, and postoperative complications were recorded in the two groups. AOFAS and VAS scores were used to evaluate the function and pain degree of the affected foot. Meary angle and Pitch angle were measured on the X-ray film, and the joint fusion was observed after operation. The difference (change value) of the above indexes before and after operation was calculated for comparison between groups to evaluate the difference in effectiveness. Results: The operation was successfully completed in both groups, and the incisions in the two groups healed by first intention. The operation time and cost in the bone grafting group were significantly more than those in the non-bone grafting group ( P<0.05). All patients were followed up. The median follow-up time was 41.0 months (range, 16-77 months) in the non-bone grafting group and 40.0 months (range, 16-80 months) in the bone grafting group. There was skin numbness of the medial dorsalis of the foot in 1 case, internal fixation stimulation in 2 cases, and pain at the iliac bone harvesting area in 1 case of the bone grafting group. There was skin numbness of the medial dorsalis of the foot in 1 case and muscle atrophy of the lower limb in 1 case of the non-bone grafting group. There was no significant difference in the incidence of complications between the two groups ( P>0.05). At last follow-up, the AOFAS scores of the two groups significantly improved when compared with those before operation, while the VAS scores significantly decreased, the anteroposterior/lateral Meary angle and Pitch angle significantly improved, and the differences were significant ( P<0.05). There was no significant difference in the change values of outcome indicators between the two groups ( P>0.05). There was no delayed bone union or bone nonunion in both groups, and joint fusion was achieved at last follow-up. Conclusion: In the treatment of MWD, there is no significant difference in effectiveness and imaging improvement of talonavicular-cuneiform joint fusion combined with or without bone grafting. However, non-bone grafting can shorten the operation time, reduce the cost, and may avoid the complications of bone donor site.

OBJECTIVE: Chronic foot pain, a common cause of forelimb lameness, can be treated by palmar digital neurectomy (PDN). Complications include neuroma formation and lameness recurrence. In humans, neuroanastomoses are performed to prevent neuroma formation. The aim of the study was to evaluate the outcome of horses undergoing dorsal-to-palmar branch neuroanastomosis following PDN. STUDY DESIGN: Retrospective case series. ANIMALS: Eighty-five horses with PDN and dorsal-to-palmar branch neuroanastomosis. METHODS: Medical records for horses undergoing this procedure at two hospitals between 2015 and 2020 were reviewed. Palmar and dorsal nerve branches of the PDN were transected and end-to-end neuroanastomosis was performed by apposition of the perineurium. Follow-up was obtained from medical records and telephone interviews. Success was defined as resolution of lameness for at least one year. RESULTS: Lameness resolved following surgery in 81/85 (95%) horses with 57/84 (68%) sound at one year. Postoperative complications occurred in 19/85 (22%) cases. The main limitations of the study were an incomplete data set, inaccurate owner recall, and variations in procedure. CONCLUSION: Compared to previous studies, this technique resulted in similar numbers of horses sound immediately after surgery, a comparable rate of postoperative neuroma formation but a higher recurrence of lameness rate at 1 year postoperatively. CLINICAL SIGNIFICANCE: End-to-end neuroanastomosis of the dorsal and palmar branches of the PDN does not reduce the rate of neuroma formation in horses. Long-term outcome was less favorable compared to previously reported PDN techniques.

BACKGROUND: Midfoot arthrodesis is regarded as the main surgical approach for treating Müller-Weiss disease (MWD). This study aimed to investigate the incidence of postoperative pain during MWD treatment through midfoot reduction or malreduction during arthrodesis and to explore the factors influencing postoperative pain in patients with MWD. METHODS: A total of 67 patients with MWD were recruited and divided into two groups according to whether midfoot alignment was reduced: reduction group (n = 38) and malreduction group (n = 29). Demographic characteristics before the operation and at the last follow-up, as well as clinical and radiographic parameters, were compared between the two groups. Clinical parameters included the American Orthopaedic Foot & Ankle Society score and visual analog scale score, whereas radiographic parameters included the calcaneal pitch angle, lateral Meary's angle, talometatarsal-1 angle dorsoplantar (TMT1dp), talocalcaneal angle dorsoplantar (Kite angle), talonavicular coverage angle, and medial navicular pole extrusion. Postoperative complications and incidence of midfoot pain were evaluated at the last follow-up visit. RESULTS: The reduction group exhibited better clinical and radiological parameters, including the TMT1dp and medial navicular pole extrusion, than the malreduction group at the last follow-up (all P < .05). However, the calcaneal pitch angle, lateral Meary's angle, Kite angle, and talonavicular coverage angle did not significantly differ between the two groups (all P > .05). The overall incidence of midfoot pain was 26.4%. The reduction group showed a lower incidence of medial pain than the malreduction group (15.7% vs. 40.0%, P < .05). Regression analysis revealed that midfoot abduction, represented by the TMT1dp, was a critical factor for midfoot arthrodesis failure and that medial navicular pole extrusion was not correlated with postoperative midfoot pain. CONCLUSION: Midfoot reduction arthrodesis yields better clinical outcomes than malreduction arthrodesis. The TMT1dp, representing midfoot abduction, is a key factor for midfoot arthrodesis failure. The extruded medial navicular bone may not affect postoperative medial midfoot pain. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

OBJECTIVE: Müller-Weiss disease (MWD) is a challenging condition involving the perinavicular region in the initial stages and subsequently the entire foot in the later stages. The goal of this article is to describe the pathomechanics, clinical evaluation, and nonoperative and operative treatment, including a treatment algorithm, based on current evidence and the combined authors' experience. DESIGN: We review the related articles and summarize the information about this condition. RESULTS: A number of related articles reveal that the treatments should focus on the management of degenerative regions and deformity correction to restore normal foot alignment and provide pain relief. CONCLUSION: This systematic review proposes a treatment algorithm that is comprehensive and practical to apply for the management of MWD.

No consensus exists regarding operative treatment of Müller-Weiss disease (MWD). Its only classification is based solely on Méary's angle and serves neither as guide to management nor prognosis. We report on 33 feet that underwent surgery following failed conservative management. Treatment was directed towards joint(s) involved, as determined by clinical examination, plain radiography and SPECT-CT. Thus, surgery consisted of isolated talonavicular in 6 feet, triple in 8, subtalar and talonavicular in 7, talonaviculocuneiform in 4, talonaviculocuneiform with interpositional tricortical iliac crest graft in 6 and pantalar arthrodesis in 2. PROMIS scores for pain interference and depression decreased significantly (p < .001) with significant accompanying increase in physical function (p = .003). Union occurred in 31 of 33 feet (94%) with complete resolution of pain at an average follow-up of 84 months. Of the 2 nonunions, 1 had fracture through the lateral navicular, and the other marked sclerosis and avascularity of the lateral navicular. We describe our pathways for selecting arthrodesis based on the joints affected. Isolated talonavicular arthrodesis was performed in early stages of MWD, which begins at the talonavicular articulation. When disease extended to both sides of the navicular, we performed talonaviculocuneiform arthrodesis. When considering isolated talonavicular, double medial or triple arthrodesis, there should be adequate cancellous bone stock remaining in the lateral part of the navicular, as determined on medial oblique radiographs and CT scan. In case of inadequate bone stock or fracture through the lateral navicular, talonaviculocuneiform arthrodesis with interpositional iliac crest bone graft is recommended.

This study investigates whether clinical examination is as sensitive as ultrasound and magnetic resonance imaging (MRI) in the diagnosis and localization of symptomatic interdigital neuroma. A retrospective cohort study was conducted at two tertiary centers on all consecutive patients who underwent excision by a single foot and ankle specialist surgeon for a presumed interdigital neuroma between January 2008 and December 2020. Investigators collected preoperative clinical findings, radiological investigations, and postoperative outcomes. Sensitivity and positive predictive values were calculated and Z-score for 2 populations proportions was performed. One hundred fourteen consecutive patients were operated on for 131 suspected interdigital neuroma. Thirteen patients were excluded due to lack of adequate clinical documentation. Of the remaining 101 patients with 118 suspected interdigital neuroma, 115 were confirmed histologically (97.5%). The sensitivity of clinical assessment to accurately diagnose and place an interdigital neuroma in the correct space was calculated as 96.5%. The most common preoperative clinical feature was pain (99.2%). The calculated sensitivity for ultrasound to accurately diagnose an interdigital neuroma was 83.6%, and to correctly locate neuroma was 79.5% respectively, which were both statistically different compared to clinical assessment (p value: <.001 and p value: <.001). The calculated sensitivity for MRI to accurately diagnose an interdigital neuroma was 93.6%, which was statistically different to clinical assessment (p value: .005). Preoperative clinical assessment has the highest sensitivity to accurately diagnose interdigital neuroma when compared to MRI and ultrasound. Preoperative clinical assessment has higher sensitivity to accurately locate interdigital neuroma when compared to ultrasound.

PURPOSE: Evaluate the functional health status and quality of life of patients diagnosed with Müller-Weiss disease and, secondarily, determine the influence of factors such as gender, social status, race, body mass index, and surgical and non-surgical treatment in patient outcome. METHODS: This study included 30 affected feet (18 patients) with follow-up from 2002 to 2016. Five patients were excluded from reassessment, resulting in 20 feet (13 patients). Questionnaires for functional and quality of life assessments were administered, and statistical analysis was performed. RESULTS: Patients with obesity had poor functional results and low quality of life rates. Regarding quality of life, mainly in the mental health domain, there was a significant difference (p < 0.001) that was not observed in other domains investigated, except for surgical treatment, which was superior to non-surgical treatment in terms of the physical domain (p = 0.024). Bilateral treatment was also superior to unilateral treatment in Coughlin's classification (71.4% versus 66.7%). CONCLUSIONS: Müller-Weiss disease evolved with poor functional results and low quality of life rates in patients with obesity, with no method of treatment influence on patient outcome, except for the SF-12 physical domain, where surgical treatment showed better results than conservative treatment.

BACKGROUND: The single existing classification of Müller-Weiss Disease (MWD), based solely upon Méary's angle, serves neither as guide for prognosis nor treatment. This accounts for lack of gold standard in its management. METHODS: Navicular compression, medial extrusion, metatarsal lengths, Kite's, lateral and dorsoplantar talo-first metatarsal angles were measured in 95 feet with MWD. Joints involved, presence and location of navicular fracture were recorded. RESULTS: Group 1 "early-onset" MWD feet (n = 11) had greatest compression and medial extrusion, and lowest Kite's angles. All except 1 were index minus and had lateral navicular fracture. Only 1 had moderate degeneration at the talonavicular joint (TNJ) with none requiring surgery yet. Group 2 "Müller-Weissoid" feet (n = 23) had radiologically normal navicular in their fifties and developed MWD on average 5 years later. They had the lowest compression and extrusion, and highest Kite's angles. None had complete fracture. All had TNJ arthritis, with early changes at lateral naviculocuneiform joint (NCJ) in 43%. Group 3 "late-onset" MWD presented in the sixth decade. Only TNJ was involved in Group 3 A (n = 16). Group 3B (n = 20) affected TNJ more than NCJ and had the greatest number of Maceira stage V disease. Group 3 C "reverse Müller-Weiss disease", which affected NCJ more than TNJ (n = 25), had greatest midfoot abduction and overlength of the second metatarsal. No fracture occurred in group 3 A compared to 65% and 32% in groups 3B and 3 C, respectively. CONCLUSIONS: With need to compare like-for-like pathology, the proposed classification provides a common platform for reporting outcomes of different treatments. We theorize pathogenetic pathways in the various groups.

Epithelioma cuniculatum (EC) is a subtype of verrucous carcinoma (VC) that affects the feet. Treatment involves complete tumor removal by wide local excision (WLE) or Mohs micrographic surgery (MMS). Extensive local destruction may require amputation. We sought to compare reported treatment methods for EC and determine their efficacy by assessing for tumor recurrence and treatment-associated complications. A systematic review of the literature spanning multiple databases was performed. To date, surgical excision is recommended as the standard of care for treatment of EC, with amputation considered in more advanced cases. Mohs micrographic surgery appears to be a promising treatment modality for EC and may have lower recurrence rates than WLE but requires further investigation.

BACKGROUND: Surgical stabilisation of the distal phalanx (DP) is a potential therapeutic strategy for severe acute laminitis. OBJECTIVE: To evaluate the effects of locking compression plate (LCP) fixation of the DP to the dorsal hoof wall. STUDY DESIGN: Ex vivo and in vivo experiments. METHODS: A T-shaped LCP was applied to one limb per pair in six pairs of cadaver forelimbs subjected to a combination of thermally induced lamellar failure and vertical load to simulate severe acute laminitis. Standard radiographic measurements were used to compare DP displacement. The LCP was then applied to one forefoot in 12 healthy Standardbred horses either standing (n = 6) or under general anaesthesia (n = 6). Lameness was evaluated daily, then horses were euthanised (day 8) and lamellar tissue analysed using light microscopy, histomorphometery and molecular markers of apoptosis. RESULTS: In the cadaver limb model, LCP fixation prevented the significant changes in hoof-distal phalanx distance, coronary extensor process distance and sole depth that characterised DP displacement in untreated limbs (p < 0.05). Application of the construct in vivo was well tolerated with minimal lameness (10/12 horses were sound at the trot on day 8); however, histology revealed dorsal lamellar pathology consistent with laminitis, but with extensive keratinocyte apoptosis. Adjacent to the LCP, caspase-3 positive cell counts were approximately 20-fold higher than control (p < 0.001). MAIN LIMITATIONS: Pathology was evaluated at a single time point. Microvascular perfusion was not evaluated. CONCLUSIONS: Rigid fixation of the DP to the hoof capsule was achieved with the LCP construct in a cadaver limb laminitis model. In live horses, LCP fixation caused regional lamellar pathology with extensive apoptosis, likely due to disturbed lamellar microvascular perfusion and/or mechanostasis. Understanding these mechanisms is critical for refinement of the technique in order to avoid iatrogenic lamellar damage.

The contents of the plantar intermetatarsal tunnel (PIMT) and the relationship between the common plantar interdigital nerve (CPIN) and the PIMT were recorded. The width of the PIMT was measured at the metatarsal neck (MTN), metatarsophalangeal (MTP) joint and the base of the proximal phalanx (BPP). The length of the deep transverse metatarsal ligament (DTML), the PIMT and the intracapsular ligament (ICL) were also measured. The PIMT was revealed to be a narrow osseofibrous tunnel divided into 3 segments by the DTML: the distal section, the area under the DTML (middle) and the proximal section. The length of the middle section was 12.77 mm in the second intermetatarsal (IM) space and 10.18 mm in the third IM space. The lengths of the distal sections were 15.52 and 14.95 mm in the second and third IM spaces, respectively. There was some soft tissue between the CPIN and PIMT, and the CPIN was observed not to glide freely within the tunnel. The widths of the PIMT at the MTN, MTP joint and BPP were respectively 2.87, 2.56, and 3.42 mm in the second IM space and 3.10, 2.68 and 3.61 mm in the third IM space. The ICL lies between the capsules of the MTP joint, and the length of the ICL was 2.76 and 3.03 mm in the second and third IM spaces, respectively. The PIMT was found to be a complex spatial structure, and the ICL might prevent the CPIN from being squeezed into the IM space.
