Combined Dexamethasone and Dexmedetomidine as Adjuncts to Popliteal and Saphenous Nerve Blocks in Patients Undergoing Surgery of the Foot or Ankle: A Randomized, Blinded, Placebo-controlled Clinical Trial.

BACKGROUND: Both dexamethasone and dexmedetomidine increase the duration of analgesia of peripheral nerve blocks. The authors hypothesized that combined intravenous dexamethasone and intravenous dexmedetomidine would result in a greater duration of analgesia when compared with intravenous dexamethasone alone and placebo. METHODS: The authors randomly allocated participants undergoing surgery of the foot or ankle under general anesthesia and with a combined popliteal (sciatic) and saphenous nerve block to a combination of 12 mg dexamethasone and 1 µg/kg dexmedetomidine, 12 mg dexamethasone, or placebo (saline). The primary outcome was the duration of analgesia measured as the time from block performance until the first sensation of pain in the surgical area as reported by the participant. The authors predefined a 33% difference in the duration of analgesia as clinically relevant. RESULTS: A total of 120 participants from two centers were randomized and 119 analyzed for the primary outcome. The median [interquartile range] duration of analgesia was 1,572 min [1,259 to 1,715] with combined dexamethasone and dexmedetomidine, 1,400 min [1,133 to 1,750] with dexamethasone alone, and 870 min [748 to 1,138] with placebo. Compared with placebo, the duration was greater with combined dexamethasone and dexmedetomidine (difference, 564 min; 98.33% CI, 301 to 794; P < 0.001) and with dexamethasone (difference, 489 min; 98.33% CI, 265 to 706; P < 0.001). The prolongations exceeded the authors' predefined clinically relevant difference. The duration was similar when combined dexamethasone and dexmedetomidine was compared with dexamethasone alone (difference, 61 min; 98.33% CI, -222 to 331; P = 0.614). CONCLUSIONS: Dexamethasone with or without dexmedetomidine increased the duration of analgesia in patients undergoing surgery of the foot or ankle with a popliteal (sciatic) and saphenous nerve block. Combined dexamethasone and dexmedetomidine did not increase the duration of analgesia when compared with dexamethasone.

The investigation of effect on foot plantar massage on functional recovery in older adults with general surgery, randomized clinical trial.

OBJECTIVE: Foot massage is known to be effective on the emotional state (anxiety, depression, etc.) in the postoperative period. However, studies on its effect on functional level are insufficient. AIM: The study aimed to investigate the impact of foot plantar massage on functional recovery in older adults undergoing general surgery, employing a randomized clinical trial design. METHODS: A total of 70 older adults aged 65 years and above who underwent abdominal surgery were included. Various assessments were conducted, including pain levels (Visual Analogue Scale), fear of mobility (Tampa Scale for Kinesiophobia), functional independence (Functional Independence Measure), balance (Berg Balance Scale), basic mobility (Rivermead Mobility Index), mental function status (Standardized Mini-Mental State Examination), and delirium (Nu-DESC). RESULTS: Statistically significant differences were observed in some assessment parameters within the groups during the 2nd and 3rd measurement times, with the intervention group demonstrating significant mean differences. DISCUSSIONS: The literature underscores the increase in kinesiophobia scores post-general/abdominal surgery in older adults, emphasizing the importance of evaluating functional level and kinesiophobia to expedite discharge processes and potentially plan early post-discharge rehabilitation to mitigate readmissions for functional reasons. CONCLUSIONS: Ultimately, foot massage was found to be effective in reducing kinesiophobia, improving balance, mobility, daily living skills, and mental status in older adults post-abdominal surgery, thereby advocating for the facilitation of post-discharge rehabilitation programs or the reduction of readmission rates. THE CLINICAL TRIALS NUMBER: NCT05534490.

An Approach to Recurrent Clubfoot Deformity in Adolescents.

Even under ideal circumstances, recurrence of infantile clubfoot deformity following the Ponseti method of treatment is to be expected to occur in as many as 20% of patients. When encountered early in childhood, these recurrences are usually amenable to further casting and limited surgery. Creation of a plantigrade foot, however, becomes much more challenging when recurrences present during adolescence and early adulthood. Because of the stiffer nature of these deformities in older patients, the fact that they are often more severe because of varying lengths of neglect, and the often deleterious effects of prior intra-articular surgeries on joint health, a principled approach is recommended for both the assessment of these feet and development of an appropriate treatment plan. In doing so, the surgeon can select the combination of nonsurgical and surgical interventions that allows for as little surgery as possible to create a plantigrade foot while maintaining any motion that is present before treatment. Although no single algorithmic approach can be applied to the variety of deformities and potentially complicating factors that are encountered in treating such patients, an understanding of the utility of preoperative casting, gradual and acute corrective techniques, and the importance of identifying and mitigating deforming forces and tendon imbalance can greatly optimize outcomes.

Improving the Accuracy of Metatarsal Osteotomies in Minimally Invasive Foot Surgery Using a Digital Inclinometer: Preliminary Study.

Minimally invasive foot surgery (MIS) has become a common procedure to treat various pathologies, and accuracy in the angle of metatarsal osteotomies is crucial to ensure optimal results. This randomized controlled trial with 37 patients investigates whether the implementation of a digital inclinometer can improve the accuracy of osteotomies compared to traditional freehand techniques. Patients were randomly allocated to group A (n = 15) receiving inclinometer-assisted surgery or group B (n = 22) receiving conventional surgery. Osteotomies were performed and outcomes were evaluated using an inclinometer. The inclinometer group showed a significant decrease in plantar pressure from 684.1 g/cm2 pretreatment to 449.5 g/cm2 post-treatment (p < 0.001, Cohen's d = 5.477). The control group decreased from 584.5 g/cm2 to 521.5 g/cm2 (p = 0.001, Cohen's d = 0.801). The effect size between groups was large (Cohen's d = -2.572, p < 0.001). The findings indicate a significant improvement in accuracy and reduction in outliers when using an inclinometer, suggesting that this technology has the potential to improve surgical practice and patient outcomes in minimally invasive metatarsal osteotomies.

Impact of the medial displacement calcaneal osteotomy on foot biomechanics: a systematic literature review.

INTRODUCTION: Progressive collapsing foot deformity (PCFD), formally known as "adult-acquired flatfoot deformity" (AAFFD), is a complex foot deformity consisting of multiple components. If surgery is required, joint-preserving procedures, such as a medial displacement calcaneal osteotomy (MDCO), are frequently performed. The aim of this systematic review is to provide a summary of the evidence on the impact of MDCO on foot biomechanics. MATERIALS AND METHODS: A systematic literature search across two major sources (PubMed and Scopus) without time limitation was performed according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) criteria. Only original research studies reporting on biomechanical changes following a MDCO were included. Exclusion criteria consisted of review articles, case studies, and studies not written in English. 27 studies were included and the methodologic quality graded according to the QUACS scale and the modified Coleman score. RESULTS: The 27 included studies consisted of 18 cadaveric, 7 studies based on biomechanical models, and 2 clinical studies. The impact of MDCO on the following five major parameters were assessed: plantar fascia (n = 6), medial longitudinal arch (n = 9), hind- and midfoot joint pressures (n = 10), Achilles tendon (n = 5), and gait pattern parameters (n = 3). The quality of the studies was moderate to good with a pooled mean QUACS score of 65% (range 46-92%) for in-vitro and a pooled mean Coleman score of 58 (range 56-65) points for clinical studies. CONCLUSION: A thorough knowledge of how MDCO impacts foot function is key in properly understanding the postoperative effects of this commonly performed procedure. According to the evidence, MDCO impacts the function of the plantar fascia and Achilles tendon, the integrity of the medial longitudinal arch, hind- and midfoot joint pressures, and consequently specific gait pattern parameters.

Success of transmetatarsal amputation for limb salvage in patients with peripheral artery disease.

Limb salvage is a difficult path for patients to travel as there is no guarantee of the outcome, often the major factor is perfusion. For patients who underwent transmetatarsal amputation (TMA), success rate is crucial as the next option is most likely a major amputation. We performed a 10 years (2010-2020) retrospective review of patients that underwent a TMA and had an angiogram or computed tomography angiography (CTA) perioperatively at the Dallas VA Medical Center. Failure after TMA was defined as a patient requiring a proximal amputation within 1 year. There were 125 TMAs performed between 2010 and 2020 at the institution. Forty-four (35.2%) patients had an angiogram/CTA peri-operative and met the inclusion criteria. Seventeen subjects (38.6%) had a higher level of amputation. Of the 17 failures, 2 (11.8%) patients had no patent vessel runoff to the foot, 9 (52.9%) had one vessel, 4 (23.5%) had two vessels, and 2 (11.8%) had three vessels runoff. One vessel runoff to the foot yielded a high rate of poor outcomes (56.3%) defined as a higher level of amputation. Two or more vessels runoff to the foot had over 75% success of limb salvage with a TMA.

[Long-term results of plantar skin grafts versus skin grafts of hairy areas for covering loss of skin substances on the palmar surface of the fingers, palm of the hand and sole of the foot in patients with black skin. Prospective cohort study of 123 total skin grafts]. / Résultats à long terme des greffes de peau plantaire versus greffes de peau des zones velues pour la couverture des pertes de substances cutanées de la face palmaire des doigts, de la paume de main et de la plante du pied chez les patients à peau noire. Étude de cohorte prospective de 123 greffes de peau totale.

CONTEXT: Despite the use of total skin grafting in the treatment of loss of skin substances on the palmar surface of the fingers, the palm of the hand and the sole of the foot, the data published in the literature on long-term results in black-skinned patients are non-existent. METHODS: The present study, filling this gap, used data from a prospective cohort of 123 total skin grafts performed on 93 black African patients who benefited from plantar skin grafts versus skin grafts from hairy areas to cover loss of skin substances. of the palmar surface of the fingers, the palm of the hand and the sole of the foot. This study covers a period of 163 months. RESULTS: Sixty-four grafts of hairy areas were carried out in 52 patients, 29 of whom were male and 23 female, for a M/F sex ratio of 1.3; and 59 plantar skin grafts in 41 patients including 21 males and 20 females, M/F sex ratio of 1. The digital palmar surface was the most recipient of the plantar graft, i.e. 35.5% of cases. After a post-operative follow-up of at least 12 months, patients or their entourage judged the functional and aesthetic results of plantar skin grafts to be better and acceptable, unlike the results of hairy area grafts. The texture and color are even better if the total skin graft is taken from an identical histological area. CONCLUSION: In view of these results, we recommend a plantar skin graft for black-skinned patients to cover losses of skin substances on the palmar surface of the fingers, the palm of the hand and the sole of the foot, if indicated.

[Minimally invasive intelligent innovative technologies in foot and ankle surgery: development status and prospects].

The rapid development of technology has ushered in a new era of minimally invasive and intelligent surgery.Minimally invasive surgeries, such as small incision, percutaneous surgery, arthroscopic surgery, and endoscopic surgery, have contributed to less invasive surgical trauma, better cosmesis, and faster recovery. Furthermore, the recent adoption of artificial intelligence (AI) has introduced new assistances and tools for minimally invasive foot and ankle surgery. By the help of advanced AI algorithms, surgeons can accurately make diagnose and personalized treatment strategies. Applications of computer-assisted navigation systems and robotics have facilitated precise surgical procedures and real-time confirmation of surgical outcomes. Foot and ankle surgery has lagged behind other surgical specialties in adopting these advancements. Currently, the integration of various forms of minimally invasive surgery and AI technology stand as the main trend in the development of foot and ankle surgery. It is believed that in the near future, intelligent minimally invasive surgery will become the mainstream in the domain of foot and ankle.

EFAS Score - Validation of Danish Version by the Score Committee of the European Foot and Ankle Society (EFAS).

BACKGROUND: The Score Committee of the European Foot and Ankle Society (EFAS) developed, validated, and published the EFAS Score in 13 languages. Currently, the Danish version completed data acquisition and underwent further validation. METHODS: The data were collected pre-operatively and post-operatively at a minimum follow-up of 3 months and mean follow-up of 6 months. Item reduction, scale exploration, confirmatory analyses and responsiveness were executed using classical test theory and item response theory. RESULTS: The internal consistency was confirmed in the Danish version (Cronbach's Alpha 0.88). The Standard Error of Measurement (SEM) was 0.31 and is similar to other language versions. Between baseline and follow-up, 77.2% of patients showed an improvement on their EFAS score, with adequate responsiveness (effect size 1.05). CONCLUSIONS: The Danish EFAS Score version was successfully validated in patients with a wide variety of foot and ankle pathologies. All score versions are freely available at www.efas.net.

The efficacy and safety of ankle blocks for foot and ankle surgery: A systematic review with meta-analysis and trial sequential analysis.

BACKGROUND: Peripheral nerve blocks may be essential elements in a multimodal pain management regime following foot and ankle surgery. We assessed the effects of ankle blocks compared with no intervention/sham block or a sciatic nerve block in patients undergoing surgery of the foot or ankle. METHODS: We searched CENTRAL, Medline, and Embase for randomised clinical trials comparing ankle block with no intervention/sham block or a sciatic nerve block for patients undergoing surgery of the foot or ankle. Our primary outcomes were duration of analgesia and cumulative 24-hour opioid consumption. We followed the recommendations of the Cochrane Handbook, and performed meta-analysis, Trial Sequential Analysis (TSA), and assessed the risk of bias and certainty of the evidence using the GRADE approach. RESULTS: We included five trials (362 participants) comparing ankle block with no intervention/sham block and three trials (247 participants) comparing ankle block with a sciatic nerve block. Ankle block may increase the duration of analgesia when compared with no intervention/sham block (MD 431 min; 96.7% CI 208 to 654), but the evidence was very uncertain. Duration was decreased when compared with a sciatic nerve block (MD -410 min; 96.7% CI -462 to -358). The ankle block duration was probably important in both comparisons. The effects on cumulative 24-hour opioid consumption were very uncertain in both comparisons. CONCLUSIONS: Ankle block may increase the duration of analgesia when compared with no intervention/sham block, but the evidence was very uncertain, and decrease the duration of analgesia when compared with a sciatic nerve block. The ankle block duration was probably clinically important in both comparisons. The effects on cumulative 24-hour opioid consumption were very uncertain.

Proximity of percutaneous tibial nerve stimulation needle insertion to surrounding anatomic structures: a cadaveric study.

BACKGROUND: Percutaneous tibial nerve stimulation is a third-line treatment for overactive bladder and urgency urinary incontinence. During the procedure, a needle is inserted cephalad to the medial malleolus and posterior to the tibia. In recent years, permanent implants and leads have been developed for insertion into the medial ankle via a small incision. There are many important structures present in the medial compartment of the ankle, including the great saphenous vein, saphenous nerve, tibial nerve, posterior tibial vessels, and tendons of the posterior compartment leg muscles. OBJECTIVE: The primary objective of this study was to identify the proximity of the percutaneous tibial nerve stimulation needle placed per Food and Drug Administration-approved device instructions to nearby important anatomic structures. The secondary objectives were to identify the proximity of the tibial nerve to the needle site, identify clinically relevant ankle anatomic structures, and confirm the tibial nerve and posterior tibial vasculature by histologic analysis. STUDY DESIGN: Detailed medial ankle dissections were performed bilaterally on 10 female lightly embalmed anatomic donors (cadavers) obtained from the Willed Body Program at the University of Louisville. A pin was inserted at the percutaneous tibial nerve stimulation needle site, and the medial ankle was minimally dissected so the surrounding anatomic structures were visible but not disrupted. The shortest distance from the pin to the selected structures of the medial ankle region was measured. On completion of each dissection and set of measurements, tissue was harvested for histologic examination. The distances between the pin and each structure were assessed using means and standard deviations. A paired t test was used to assess the difference in the locations between the left and right ankles. Statistical analysis was performed on left-sided, right-sided, and combined measurements. An 80% prediction interval was found to represent the expected range of values for the measurement of a new cadaver or patient, and the 95% confidence interval of the mean was computed to characterize the average distance across all cadavers or patients. RESULTS: The medial ankle of 10 adult female lightly embalmed cadavers were examined bilaterally. Dissections were completed from October 2021 to July 2022. Of note, 80% prediction intervals for the tibial nerve, the posterior tibial artery or vein, and the flexor digitorum longus tendon had a lower range of 0.0 mm from the pin and extending to 12.1, 9.5, and 13.9 mm, respectively. Moreover, 2 of the structures were found to be asymmetrical between the right and left ankles. The great saphenous vein was further from the pin on the left (20.5 mm [standard deviation of 6.4 mm] on the left vs 18.1 mm [standard deviation of 5.3 mm] on the right; P=.04). The calcaneal (Achilles) tendon was further from the pin on the right side (13.2 mm [standard deviation of 6.8 mm] vs 7.9 mm [standard deviation of 6.7 mm]; P=.04). Tibial neurovascular structures were confirmed with microscopic analysis. CONCLUSION: The anatomic structures within the medial ankle lie unexpectedly close to the percutaneous tibial nerve stimulation needle site as noted per Food and Drug Administration-approved device instructions. There is a possibility that some medial ankle structures are not symmetrical. It is crucial that practitioners understand medial ankle anatomy when performing percutaneous tibial nerve stimulation or permanent device insertion.

Donor Foot Morbidity Following Nonvascularized Toe Phalanx Transfer Utilizing a New Reconstruction Technique.

BACKGROUNDS: Nonvascularized toe phalanx transfer is an accepted surgical option for short and hypoplastic digits in congenital hand abnormalities. However, one of the criticisms of this technique is the donor site morbidity. The purpose of this study was to evaluate donor foot morbidity after nonvascularized toe phalanx transfer using a new donor site reconstruction technique. METHODS: We retrospectively reviewed 116 nonvascularized toe phalanx transfers in 69 children between 2001 and 2020 in whom the donor foot was reconstructed with a new technique using iliac osteochondral bone graft with periosteum. Feet treated with an isolated donor proximal phalanx of the fourth toe were selected and morbidity was assessed both subjectively and objectively at a minimum of 2 years after surgery. Motion, stability, and alignment of the metatarsophalangeal joint were clinically evaluated. The relative length of the fourth toe to the third toe was measured on a roentgenogram. The satisfaction of the parents for overall function and appearance was evaluated using a visual analog scale. RESULTS: Ninety-four operated feet in 65 patients, including 43 boys and 22 girls, were included. The right foot was evaluated in 52 patients and the left foot in 42 patients. The mean age at operation was 2 years and the mean follow-up period was 7.6 years. Motion at the metatarsophalangeal joint was good at 69% with an average extension of 45 degrees and flexion of 25 degrees. Stability and alignment were good at 95% and 84%, respectively. Only 4 toes had gross instability and 4 toes with poor alignment required revision surgery. Sixty-two toes (66%) maintained proportional length and 9 toes were graded as short. Parental satisfaction was high for appearance as well as function. CONCLUSIONS: This newly described technique of using iliac osteochondral bone graft with periosteum to reconstruct toe phalanx donors provided satisfactory results. The function and appearance of the donor foot after a nonvascularized toe phalanx transfer was well preserved. LEVEL OF EVIDENCE: Level IV; therapeutic.

What exactly is "foot abduction" during management of idiopathic clubfoot in clinical practice?

PURPOSE: There is however gross ambiguity regarding the use of term "foot abduction" in clubfoot treatment. We measured below defined angles at different stages of clubfoot treatment to decipher their precise interpretation. METHODS: In a prospective evaluation of 25 unilateral clubfeet in infants' age less than six months treated with Ponseti technique, clinical leg foot and thigh foot angle were measured at talar head reduction (LHT0), pre-tenotomy, and post-tenotomy stage. A "normal" reference was available in the form of measurements of contralateral limb. RESULTS: Talar head (LHT0) was reduced at mean leg foot angle of 26 degrees. The corresponding pre- and post-tenotomy angles were 42.6 and 50.0 degrees, respectively. The reference leg foot angles for contralateral limb were 49.8 degrees. The thigh foot angle for LHT0, pre-tenotomy, post-tenotomy, and contralateral side were, respectively, 39.2, 56, 68, and 65.6 degrees. There was an additional tibial external rotation component of mean 13.4 degrees (SD 4.5) in the thigh foot angle when compared to the leg foot angle at tenotomy. This increased to 18 degrees (SD 3.4) post-tenotomy. CONCLUSIONS: The study suggested that the foot abduction described in the "Ponseti Manual" probably intends thigh foot rather than leg foot angles. There was a significant difference in the angles when talar head reduced and tenotomy was decided. The foot abduction is an ambiguous term which should be replaced by the more specific leg or thigh foot abduction angle.

Histopathological assessment of a two-stage reconstructive procedure of the infected Charcot foot.

INTRODUCTION: Charcot neuropathic osteoarthropathy (CN) can be complicated by osteomyelitis (OM). Surgery is a standard procedure to treat OM including debridement and interposition of antibiotic-loaded cement (ABLC) spacer. The course of CN and OM was investigated on a histopathological level. MATERIALS AND METHODS: Diabetic patients (n = 15) suffering from CN and midfoot OM underwent surgical debridement and interposition of ABLC was interposed. 6 weeks later, ABLC was removed and bone samples were taken again. Histopathological Charcot Score (HCS), Histopathological Osteomyelitis Evaluation Score (HOES) and microbiological assessment were used to evaluate osteomyelitic and neuroosteoarthropathic activity at both time points. RESULTS: Interposition of ABLC leads to microbiological/histopathological eradication of OM in 73%/87% of patients. CN activity-measured by HCS-could be reduced from moderate to low activity by ABLC spacer and correlated with HOES. CONCLUSIONS: CN activity could be reduced by surgery. It can be suggested that neuroosteoarthropathic activity measured by HCS is triggered by OM.

Osteoscopic versus open surgery for the treatment of enchondroma in the foot.

INTRODUCTION: The conventional treatment of enchondromas is the open surgery with curettage of lesions. Osteoscopic surgery is a minimally invasive endoscopic approach for lesions inside bone. The aim of this study was to evaluate the feasibility of the osteoscopic surgery in comparison with the conventional open surgery for patients with foot enchondromas. MATERIALS AND METHODS: A retrospective cohort study comparing patients with foot enchondromas treated with osteoscopic or open surgery from 2000 to 2019. Functional evaluations were based on both the AOFAS score and the Musculoskeletal Tumor Society (MSTS) functional rate. Complication and local recurrence were evaluated. RESULTS: Seventeen patients underwent endoscopic surgery, and eight patients underwent open surgery. The AOFAS score was higher in the osteoscopic group than the open group at 1 and 2 weeks after surgery (mean, 89.18 vs 67.25 [p = 0.001], 93.88 vs 79.38 [p = 0.004]). The MSTS functional rate was also higher in the osteoscopic group than the open group at 1 and 2 weeks after surgery (mean, 81.96 vs 59.58% [p = 0.00], 90.98 vs 75.00% [p = 0.02]). No statistical differences were found after 1-month of surgery. The osteoscopic group had lower complication rate than the open group (12 vs 50%; p = 0.04). No local recurrence was found in any groups. CONCLUSION: The osteoscopic surgery is feasible to provide earlier functional recovery and fewer complications than the open surgery.

Reulceration and Reoperation Rates After Central Ray Amputations: A Retrospective Study.

Reulceration is a common complication following ray amputations of the foot. The primary aim of this study was to evaluate the incidence of re-ulceration following isolated and combined central ray amputations. This was a retrospective review of 55 consecutive limbs that underwent central ray amputations at Wake Forest Baptist Medical Centers. Procedures were performed at the 3 central rays or a combination of central rays. Incidence of postoperative ulceration was evaluated on the ipsilateral foot. We hypothesized there would not be an association between which ray was resected and development of reulceration. 24 patients (43%) experienced repeat ulceration following a central ray amputation. Median follow up time was 17.4 months (range 4 days to 99 months). The estimated ulcer recurrence rate at 1 year was 41.8%. There was no statistical difference based on location of amputation (second, third, 4 rays) with regards to reulceration, further amputation, transmetatarsal amputation, or below knee amputations. However, reulceration seemed to be much quicker in those patients undergoing a third ray amputation. Like the medial and lateral rays, central ray amputations can be a good initial salvage procedure to clear devitalized tissue and prevent the spreading of infection. The results of the present study suggest that there is no detectable difference between location of central ray amputations and development of re-ulceration, more proximal amputations, or death among this cohort.

Progression to Hindfoot Charcot Neuroarthropathy After Midfoot Charcot Correction in Patients With and Without Subtalar Joint Arthrodesis.

Charcot neuroarthropathy (CNA) is a disabling and progressive disease that affects the bones and joints of the foot. Successful Charcot reconstruction focuses on restoring anatomic alignment, obtaining multiple joint arthrodesis, selecting stable fixation, preserving foot length, and creating a foot suitable for community ambulation in supportive shoegear. Intramedullary fixation arthrodesis of the medial and lateral columns has been previously reported to produce improvement in midfoot Charcot reconstruction. More recently, a growing trend of stabilization of the subtalar joint (STJ) has been incorporated alongside the medial and lateral column fusion. Our objectives were to retrospectively review patients who underwent midfoot Charcot reconstructive surgery, whether with or without accompanying STJ arthrodesis, and establish which patients progressed to ankle CNA. Of the 72 patients who underwent midfoot Charcot reconstruction, 28 (38.9%) underwent STJ arthrodesis, and 22 converted to ankle CNA (30.6%). Fourteen (63.6%) of 22 ankle CNA cases had not undergone STJ arthrodesis; 8 patients (36.4%) had it. A Fisher exact test was performed to identify the relationship between those without STJ arthrodesis and those progressing to ankle CNA; it revealed statistical significance (p = .001). Performing an STJ arthrodesis with midfoot Charcot reconstructive surgery may be beneficial to aiding in hindfoot stability, establishing a plantigrade foot, and providing further insight into the management of midfoot Charcot.

Clinical, Radiographic and Gait Parameters Associated with Medial Arch Pain in the Flexible Pediatric Flatfoot.

Pain in the flexible flatfoot is a common complaint, if present it is important to find its exact location and causes Therefore, the study aimed to find differences between children with and without medial arch pain and relate them to the reduction of pain following surgical treatment. Children with idiopathic flexible flatfeet were retrospectively included in the study. All children underwent a clinical, radiographic, and gait examination. The feet were subdivided into 2 groups: asymptomatic and those with medial arch pain. Factors associated with medial arch pain were identified via t test. Significant radiological and gait parameters were correlated to the change in medial arch pain score following surgery. Included were 322 feet belonging to 177 children, with the mean age of 11.8 (SD = 2.2) years. The pain was perceived in 52% of the feet, of these, 74% in the medial arch. In the group with pain, 31 feet received a gait analysis following surgery. The radiological parameters, talus-1 and -2 metatarsal angles and the gait parameter, calcaneal lateral shift during walking showed a significant difference (p ≤ .004) between the no pain and pain groups and were associated (R2 ≥0.14, p ≤ .04) with the reduction in pain following surgery. The increased talus-1 and -2 metatarsal angles and the calcaneal lateral shift may cause increased tension on the soft-tissues along the medial side of the foot and may produce pain. Therapies aiming at improving the medial arch pain should be directed to normalize the talus-1 or -2 metatarsal angles and the calcaneal lateral shift.

Intravascular Endothelial Hyperplasia of the Foot.

Intravascular endothelial hyperplasia is a benign soft tissue mass rarely reported in the foot. Advanced imaging and confirming a benign diagnosis are critical for any soft tissue mass. This paper identifies 2 patients that developed intravascular endothelial hyperplasia tumors which required surgical excision. A 17-year-old male patient presented to clinic complaining of a painful bump to the arch of his right foot which he related to an injury 9 months prior. Magnetic resonance imaging of the right foot revealed a mass within the plantar subcutaneous fat that was serpiginous in nature similar to adjacent branching vessels favoring a low-flow vascular malformation. A 38-year-old female with Multiple Sclerosis presented with complaints of persistent symptoms of pain to the 1st interspace, difficult ambulation and neuritis. Ultrasound and MRI observed solid, multilobulated mass, with internal vascular malformation, MRI describing intrinsic involvement along the abductor musculature and flexor tendons. Both lesions were surgically excised and sent for pathology. Pathology report indicated a diagnosis of intravascular papillary endothelial hyperplasia or Masson's tumor in both cases. Pathology diagnosis of intravascular papillary endothelial hyperplasia is generally good with wide resection leading to low recurrence rates. Both patients in the current study have progressed postoperatively with resolution of symptoms and without recurrence.

Clinical Outcomes Following Treatment of Recurrent Talotarsal Joint Dislocation Using a Type II Extraosseous Talotarsal Stabilization Implant-A Long-Term Follow-Up Study.

Collapsing foot deformity (CFD) and its resulting sequelae caused by recurring talotarsal joint dislocation (RTTJD) affects pediatric and adult patients. An extraosseous talotarsal stabilization (EOTTS) procedure, a subset of subtalar arthroereisis (SA) procedures, is recommended as a minimally invasive, first in-line surgical treatment option for CFD. The aim of this multicenter, retrospective study was to evaluate patient-reported outcomes measures in patients who were treated for RTTJD with Type II EOTTS implants. Sixty-seven cases having a median age of 38 years (range: 10-74) with more than 5 years of follow-up were included in this study. The mean postoperative visual analog scale and Maryland Foot Score was 1.0 ± 1.9 and 92.3 ± 11.3, respectively, indicating excellent clinical outcomes. Subjectively, 88% cases reported as being satisfied with the outcome, 94% cases said they would recommend EOTTS, and 93% said that, if necessary, they would repeat it on their contralateral foot. A subgroup analysis revealed that while not statistically significant, clinical outcomes were slightly better in pediatric patients compared to adults. Implant removal rate was 4.5% (3 cases), and these were in the adult group only. Rate of minor issues such as pain, stiffness, discomfort, etc. was 15%; however, no serious adverse effects or complications were observed in any patient. This study suggests that EOTTS is an effective surgical treatment option wherein successful long-term clinical outcomes with low failure rates can be achieved in a select patient population.
