AI-Assisted Sentiment Analysis of ACFAS Fellowship-Trained Foot and Ankle Surgeon Online Reviews.

Online physician ratings and reviews prove useful among patients when selecting a provider. Analyzing such reviews across medical and surgical specialties to determine their emotional tone through sentiment analysis yielded varying levels of positivity, negativity, and neutrality. To provide insight into what patients are saying, this study similarly analyzes the sentiment of physician ratings and reviews among foot and ankle surgeons. Healthgrades ratings and reviews, entered as of February 2024, were collected among the American College of Foot and Ankle Surgeons (ACFAS) fellows along with each surgeon's demographic information. ChatGPT was used to perform a sentiment analysis to describe the positivity, negativity, and neutrality of online physician reviews. Ratings and review sentiment were described among the sample and between sexes. Among 268 fellows, men received higher average rating scores than women (p = 0.02), From the 2,339 reviews, women received a greater proportion of negative reviews compared to men (p<0.001). The overall sentiment scores among men were higher than women (p < 0.001). There existed a very weak inverse relationship between ratings and years in practice (R = -0.16; p = 0.01). Fellowship-trained foot and ankle surgeons received predominantly positive reviews. When comparing sexes, males received higher ratings with higher sentiment scores. As patients place high credence in online reviews when selecting their provider, surgeons should remain mindful of and monitor or manage their online reputation. LEVEL OF EVIDENCE: IV.

Retrospective Comparison of Preoperative and Postoperative Foot Width in Minimally Invasive Hallux Valgus Surgery.

Minimally invasive surgery (MIS) has gained popularity for hallux valgus correction in the adult population. The advantage of reproducibility of this procedure can aid in lower operating room costs, quicker recovery, and fewer complications. The purpose of this retrospective study was to compare preoperative versus postoperative foot widths in patients that underwent MIS hallux valgus correction. The average preoperative foot width was 101.1 ± 5.67 mm and postoperatively the foot width measured at 12-month follow-up was 95.9 ± 4.92 mm, which was statistically significant (p < .001). Overall, there was a 5.03 ± 3.71% reduction in foot width, with a statistically significant linear relationship between preoperative foot width and percent change in width following the procedure (R = -0.46; p = .003). Based on our results, we can conclude that MIS bunion surgery can effectively narrow the foot postoperatively, particularly in patients with a wider forefoot, adding cosmetic benefit to the procedure.

Comparing Outcomes of Acute Versus Gradual Surgical Correction in Brachymetatarsia.

Brachymetatarsia consists of a shortened metatarsal resulting in a shorter toe. Pain with shoe wear and cosmetic concerns are the main reasons for surgical intervention. Surgical techniques to increase metatarsal length include acute lengthening with interpositional bone grafting or gradual lengthening with callus distraction. We performed a retrospective cohort study for 1 surgeon's patients at 1 institution over 10 years. Twenty-nine feet in 22 patients met inclusion criteria for acute correction; 16 feet in 11 patients were included for gradual correction. Mean ages were 26.3 ± 12.1 and 27 ± 10.8 in the acute and gradual groups, respectively (p = .79). Most patients were female: 95.4% of acute cases and 90.1% of gradual cases. Most involved lengthening the fourth metatarsal: 86.7% and 100% of acute and gradual groups, respectively (p = .54). Correction obtained amounted to 14.4 ± 2.97 mm (range, 10-22 mm) in acute cases and 14.8 ± 2.39 mm (range, 10-20 mm) in gradual cases (p = .81). The mean percent increase in metatarsal length was 21.1 ± 14% for acute and 22.6 ± 12.4% for gradual (p = .72). Mean consolidation was 8.9 ± 2.51 weeks for acute and 21.4 ± 10.8 weeks for gradual (p = <.001). Nonunions were most common in the gradual group (37.5%) with need for more revisional surgery (43.5%) compared with the acute group; both were statistically significant. We conclude that acute brachymetatarsia correction can obtain correction similar to the gradual technique with fewer postoperative complications and less osseous consolidation time.

"No Care Pin Care" Following Charcot Reconstruction With Static External Fixation.

Charcot reconstruction with static external fixation provides stability in deformity correction. Concern for pin site health remains forefront to prevent premature fixator removal should infection develop. While previous investigations examined a spectrum of pin care protocol with a similar variation in outcomes, this study assesses results following a "no care pin care" routine. A retrospective analysis of patients with Charcot neuroarthropathy treated with static external fixation was performed where all pin sites were dressed using a chlorhexidine-soaked sponge without postoperative maintenance. Demographics, reconstruction-specific, and postoperative variables including pin site irritation, pin site infection, and pin tract infection were collected through frame removal. A comparison between uncomplicated and complicated pin sites was made. Statistical significance was set as p ≤ .05. Among 85 patients and their respective pin holes that posed potential spots of infection, 6 (7%) experienced pin site irritation and 5 (6%) experienced pin site infection. Moreover, 2 (2%) experienced a pin tract infection requiring removal. Out of the 768 wires/half-pins 2 (0.3%) were removed. There existed no statistically significant predictors of pin site irritation/infection other than age (p = .03). "No care pin care" proves an effective means at pin site care following static external fixation in Charcot reconstruction. Limited maintenance reduces the postoperative burden on providers and patients.

Minimally Invasive Versus Open Hammertoe Correction: A Retrospective Comparative Study.

Hammertoe deformity is a common forefoot pathology, characterized by a progressive deformity with dorsiflexion of the proximal phalanx on the metatarsal head at the metatarsal phalangeal joint (MTPJ) and plantarflexion of the intermediate phalanx on the proximal phalanx at the proximal interphalangeal joint (PIPJ). While there is literature available discussing open techniques for hammertoe correction, there is a lack of publications discussing minimally invasive techniques, therefore the objective of this retrospective comparative study is to evaluate minimally invasive versus open hammertoe surgery in terms of time to osseous union, complications, recurrence, and return to full activity. Sixty eight feet among 41 patients met the inclusion criteria and were surveyed. Among the 68 feet, 54 feet (124 toes) underwent minimally invasive hammertoe correction and 14 feet (22 toes) underwent open hammertoe correction. Time to osseous union (weeks) in the MIS group was 8.76 ± 2.31 weeks with similar outcomes to the open group with union at 8.42 ± 2.31 (p = .65). Return to activity (weeks) was 10.47 ± 3.45 in the MIS group and 9.92 ± 3.03 in the open group with no statistical significance (p = .62). There was 4 recurrent hammertoe deformities in the MIS group (3.23%) with no recurrent hammertoes in the open group (0%). In the MIS group 5 hammertoes had unplanned hardware removal (4.03%) compared to 0 in the open group. There was no statistical significance for both recurrence and unplanned hardware removal (p = 1). Overall, we concluded that both techniques are equivocal with no detectable statistical difference.

Landmarks for a Minimally Invasive Approach for Haglund's Deformity: A Cadaveric Study.

INTRODUCTION: Haglund's deformity is a posterosuperior calcaneal prominence often associated with a painful bursa and insertional Achilles tendinopathy. Endoscopic debridement has been previously described; however, the aim of this cadaveric study is to describe landmarks of a minimally invasive surgical (MIS) approach to Haglund's deformity. METHODS: Twelve specimens were dissected to identify medial and lateral portals for minimally invasive burr placement and anchor placement. A standard ruler was used to measure the distance in millimeters from the medial and lateral neurovascular structures in relation to medial and lateral portals. A separate 7-cm longitudinal incision posterior to the lateral malleolus and a separate 7-cm longitudinal incision posterior to the medial malleolus were made to identify at-risk neurovascular structures. RESULTS: The average distance from the sural nerve to the lateral portal was 25.7 mm (23-26). The mean distance from the lateral calcaneal branch of the sural nerve to lateral portal was 11.4 mm (10-12). The mean distance from the tibial nerve to the medial portal was 35.3 mm (35-36). Both the medial and lateral incisions were 9.3 mm from the calcaneal tuberosity. CONCLUSION: The results indicate that the MIS approach to Haglund's deformity resection can be performed reliably without neurovascular compromise. LEVELS OF EVIDENCE: Level IV.

Management of Midfoot Charcot: Minimally Invasive Techniques and Improved Fixation.

The objective of this article is to review the etiology and pathophysiology of Charcot neuroarthropathy as it contributes to the breakdown of the midfoot. The article will also discuss the emerging techniques in minimally invasive surgery and how this is applied to Charcot reconstructive surgery as well as reflect on a newer thought processes to surgical intervention.

The Role of Supramalleolar Osteotomies in Ankle Arthritis.

The supramalleolar osteotomy (SMO) is a joint-preserving surgical procedure that allows realignment of the ankle joint in severe deformity secondary to arthritis. This osteotomy realigns the mechanical axis to provide better weight distribution through the ankle joint. With an aligned mechanical axis, the overloaded asymmetric ankle joint will shift toward the preserved joint area in a valgus or varus ankle joint. The SMO also can be used via a staged approach to correct severe deformity in an end-stage arthritic ankle before total ankle arthroplasty to optimize the implant's longevity and improve overall functional outcomes.

Bilateral Digital Ischemia Secondary to Heparin-Induced Thrombocytopenia with Subsequent Limb Salvage: A Case Study.

Heparin-induced thrombocytopenia (HIT) is a prothrombotic state caused by the buildup of platelet factor 4 antibodies with decreased platelet count caused by heparin therapeutic or prophylactic therapy. It is important to detect this complication, especially in critically ill patients and cardiac patients. Detection of HIT can be demonstrated by positive antibodies in a HIT panel. Based on clinical and laboratory findings, heparin use should be discontinued with immediate transition to alternative anticoagulation therapies. Thromboembolic events can be an adverse effect of HIT and can cause local tissue necrosis, especially in the lower extremity. This case is a retrospective medical record review of a 52-year-old man who was initially admitted as an outpatient for coronary artery bypass grafting and mitral valve replacement who developed digital gangrene from HIT. This case emphasizes the rare adverse effects of HIT and the need for timely consultation for surgical treatment of limb ischemia/gangrene.

Comparison of Minimally Invasive and Open Approaches for Midfoot Charcot Neuroarthropathy Reconstruction.

Charcot neuroarthropathy (CNA) is a progressive disease affecting the bones and joints of the foot that can lead to instability, breakdown, and collapse. Minimally invasive surgery (MIS) techniques are becoming a popular option within musculoskeletal surgery of the foot and ankle and may be an alternative to aggressive dissection seen during corrective surgery. An MIS approach minimizes vascular disruption, provides structural stability at an osteotomy or arthrodesis site, and encourages early mobilization if indicated. This retrospective study compares 17 patients who underwent an open approach for midfoot CNA reconstruction with 17 patients who underwent an MIS approach for midfoot CNA reconstruction. Preoperative and postoperative radiographic parameters were measured: lateral talus-first metatarsal, anteroposterior (AP) talus-first metatarsal, calcaneal pitch, and cuboid height. Difficulties that occurred during treatment were gathered and sorted into postoperative problems (stage I), obstacles (stage II), and complications (stage III). Changes from preoperative to postoperative radiographic lateral talus-first metatarsal and AP talus-first metatarsal angles were statistically significant (p < .001) for both the MIS and open approach. No true postoperative complications (stage III) were observed at last follow-up. The most common difficulty encountered was pin-site infection (stage I; in 23.5% of patients) in the MIS group. In the open group, the most common complications were wound development (stage I; 23.5%) and nonunions (stage II; 23.5%). Our findings suggest that midfoot CNA reconstruction with MIS methods offers similar outcomes to the open approach.

Minor and Major Amputation Rates Following Midfoot Charcot Reconstructive Surgery.

Charcot neuroarthropathy (CNA) is a progressive disease that affects the bones and joints of the foot. To prevent collapse and loss of stability within the pedal architecture, CNA should be diagnosed and managed early. The objective of this retrospective study was to review patients who underwent midfoot CNA reconstructive surgery and evaluate subsequent rates of minor and major amputations. Secondary objectives include identifying patients that underwent midfoot CAN with and without a subtalar joint (STJ) arthrodesis. Out of the 72 patients, 4 (5.6%) underwent minor (digital, ray) amputation, 2 (2.8%) underwent proximal amputations (either below or above the knee), and none underwent midfoot amputation (transmetatarsal, Lisfranc, Chopart). A Fisher's exact test was employed to compare the outcomes of minor and major amputation rates in our CNA cohort with those who underwent midfoot CNA reconstruction with STJ arthrodesis and found no statistical significance (p = .15). Overall, a total progression to amputation was 8.4% following midfoot CNA reconstruction, with 2.8% of patients undergoing major amputation (below knee or above knee). Despite no statistical significance, we recommend surgeons to consider including an STJ arthrodesis in addition to midfoot CNA reconstruction to establish a stable and plantigrade foot.

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.

Ligament Insufficiency with Flatfoot: Spring Ligament and Deltoid Ligament.

The objective of this article was to review the deltoid ligament and spring ligament specifically as they pertain to ligament insufficiency and adult-acquired flatfoot deformity. Discussion includes the normal and abnormal biomechanical forces that extend through these ligaments in normal and flatfoot deformity. Current literature related to spring ligament repair as part of the flatfoot deformity reconstruction is also reviewed.

A Critical Biomechanical Evaluation of Foot and Ankle Soft Tissue Repair.

The objective of this article is to review the biomechanical stresses that occur during normal physiologic function of lower extremity soft tissue anatomic structures and to use this as a baseline for a critical analysis of the medical literature because it relates to surgical reconstruction following injury. The Achilles tendon, anterior talofibular ligament, plantar plate, and spring ligament are specifically evaluated.

Surgical Anatomy of the Endoscopic Gastrocnemius Recession.

The objective of this investigation was to analyze the surgical anatomy of the endoscopic gastrocnemius recession procedure with reference to the curved nature of the aponeurosis. A consecutive series of 34 magnetic resonance imaging scans were evaluated under the direction of a musculoskeletal radiologist. An angular calculation of the effective curvature of the aponeurosis was measured 2 cm distal to the musculotendinous junction based on the maximal posterior excursion and terminal medial and lateral edges. A frequency count was additionally performed of the number of deep intramuscular septa extending from the aponeurosis, as well as a description of the location of the neurovascular bundle in this location. The mean effective curvature was 126.5 degrees (standard deviation [SD] = 6.3 degrees, range 115-143 degrees, 95% confidence interval 124.3-128.7 degrees). We observed an average of 1.2 (SD = 0.5, range = 0-2) deep intramuscular septa extending from the aponeurosis, and that 20.6% of neurovascular bundles were located superficial to the aponeurosis in this location. In conclusion, we found that a straight cannula needs to be navigated around an approximate 125-degree angle during performance of the EGR procedure. We think that this information provides evidence of potentially unrecognized complications of this procedure and leads to future investigations demonstrating anatomic and procedural outcomes.

Approximation of the Ankle-Brachial Index in the Setting of Medial Arterial Calcific Sclerosis.

The presence of medial arterial calcific sclerosis is known to cause inaccuracy in the interpretation of noninvasive vascular testing. This substantially limits the utility of an important baseline diagnostic test for peripheral arterial disease. Therefore, the objective of this investigation was to derive a method to effectively factor out calcification in the interpretation of the ankle and digital brachial indices. The noninvasive vascular testing results of 160 subjects were stratified into the absence of calcification, mild calcification, moderate calcification, and severe calcification based on plain film radiographic findings of the infrageniculate vessels. Measurements were then performed of the pulse volume recording (PVR) waveforms at brachial, ankle and digital anatomic levels to include PVR wavelength and PVR upstroke length, with a calculation of the ratio of PVR upstroke length to PVR wavelength. These measurements were compared between groups and then correlated to the ankle and digital brachial indices. A significant difference was observed in the PVR upstroke ratio between the 3 anatomic levels (0.1818 vs 0.2622 vs 0.3191; p < .001), but not between the 4 calcification groups (0.2457 vs 0.2363 vs 0.2694 vs 0.2631; p = .242). A significant negative correlation was observed between the PVR upstroke ratio and the ankle brachial index (ABI) (Pearson -0.454; p = .002) with linear regression indicating the relationship is defined by the formula: Effective ankle brachial index = 1.17 - (1.33 × PVR upstroke ratio at ankle level). A significant negative correlation was also observed between the PVR upstroke ratio and the digital brachial index (Pearson -0.553; p < .001) with linear regression indicating the relationship is defined by the formula: Effective toe brachial index = 1.04 - (1.61 × PVR upstroke ratio at digital level). The results of this investigation demonstrate the feasibility of, and provide equations to approximate, the effective ankle brachial and toe brachial indices in the setting of medial arterial calcification.

Diagnosis, imaging, and potential morbidities of the hallux interphalangeal joint os interphalangeus.

Hallux pain is a common entity with a differential diagnoses including hallux valgus, hallux limitus/rigidus, and gout and specifically at the interphalangeal joint (IPJ), flexor hallucis longus (FHL) tenosynovitis, and joint arthrosis. An under-recognized source of pain is the os interphalangeus, an ossicle typically located at the plantar aspect of the hallucal interphalangeal joint. This ossicle is radiographically visible in its ossified form in 2-13% of individuals, but can also be present as an ossified or non-ossified nodule in patients. The os interphalangeus may be centrally or eccentrically located, and although originally believed to be a sesamoid bone in the FHL tendon, it is an ossicle located in the joint capsule of the IPJ and separated from the tendon by a bursa. When the ossicle is absent, the bursa is also absent and the tendon is attached to the joint capsule. Infrequently, the os may be located eccentrically under the first IPJ and reflect persistence of one of the distal phalanx. Rarely, the os interphalangeus may be dorsal to the IPJ. The os interphalangeus is best evaluated on radiographs, ultrasound, and MRI. Pain is a result of altered mechanics with arthrosis or frictional effects with bursitis, tenosynovitis, or intractable plantar keratosis (IPK). The ossicle may also displace into a dislocated IPJ, preventing reduction. The os interphalangeus may be centrally or eccentrically located, and although originally believed to be a sesamoid bone. This has been found within the plantar joint capsule of the distal hallucal interphalangeal joint and separated from the tendon by a bursa. Uncommonly, the location may be plantar eccentric and reflect persistence of one of the ossification centers of the distal phalanx. Although the ossicle can be imaged with standard AP and lateral radiographs in many cases, in those cases of unexplained pain with no radiographically visible ossicle, and the presence of friction blisters, intractable plantar keratosis (IPK), hyper-extension of the IPJ, hallux limitus/rigidus, or metatarsophalangeal joint (MTPJ) arthrodesis, an MRI or CT should be considered to identify a non-ossified fibrocartilaginous node. This is of particular concern in a patient with a history of underling diabetes mellitus or other metabolic disorders associated with diminished pedal sensation where neurotrophic changes place them most at risk for complications associated with excessive plantar pressure. Pain is a result of altered biomechanics with arthrosis, or frictional effects causing bursitis, tenosynovitis, or IPK. The ossicle may also displace into a dislocated IPJ, preventing reduction. In this article, we will describe the anatomy and imaging appearance of the common os interphalangeus variants and associated complications including frictional effects, arthrosis, and IPK and discuss conservative and surgical management of a symptomatic ossicle.

A Comparison of Adverse Short-Term Outcomes Following Forefoot Amputation Performed on an Inpatient Versus Outpatient Basis.

The objective of this investigation was to evaluate short-term adverse outcomes following forefoot amputation with a specific comparison between those procedures performed on an inpatient versus outpatient basis. The 2018 American College of Surgeons National Surgical Quality Improvement Program database was interrogated to select those subjects with a 28805 current procedural terminology code (amputation, foot; transmetatarsal) that underwent the procedure with "all layers of incision (deep and superficial) fully closed." This resulted in 326 subjects who underwent the procedure on an inpatient basis and 72 subjects who underwent the procedure on an outpatient basis. Results of the primary outcome measures found no significant differences between groups with respect to the development of a superficial surgical site infection (5.8% vs 5.6%; p = .950), deep incisional infection (3.4% vs 5.6%; p = .380), or wound disruption (3.4% vs 6.9%; p = .163). Additionally, no significant differences were observed between groups with respect to unplanned reoperations (15.6% vs 12.5%; p = .500) or unplanned hospital readmissions (21.8% vs 23.6%; p = .957). The results of this investigation demonstrate no difference in short-term adverse outcomes following the performance of forefoot amputation with primary closure when the procedure is performed on an inpatient or outpatient basis. We hope that this information is utilized in future investigations specifically examining this clinical scenario as it relates to hospital admission criteria related to lower extremity tissue loss, length of hospital stay considerations, the timing of partial foot amputation following revascularization, and the economics of limb preservation.

Responsiveness and Inter-Rater Reliability of the Pulse Volume Recording Upstroke Ratio (PVRr).

The objective of this study was to evaluate a measure of the responsiveness and reliability of the pulse volume recording upstroke ratio (PVRr). A database of 389 subjects undergoing lower extremity revascularization was analyzed. Subjects were included in the analysis if they had undergone pedal radiographs, had PVRs performed pre- and postlower extremity revascularization, and had regular pulsatile digital waveforms with a pressure recording on both PVRs. The responsiveness of the PVRr was assessed by means of the postoperative percent change in comparison to the digital pressures. A statistically significant negative correlation was observed (Pearson -0.421; p = .007) indicating that as digital pressures increased, the PVRr decreased. Further, measurement of the reliability of the PVRr was performed on a selection of 10 recordings by 2 residents and 3 board-certified surgeons. The observed intraclass correlation coefficient of measurements was 0.960. Results of this investigation provide evidence in support of the responsiveness and inter-rater reliability in the calculation of the pulse volume recording upstroke ratio.

Normal Distal Excursion of the Peroneus Brevis Myotendinous Junction.

A low-lying peroneus brevis muscle belly has been described as a risk factor for the development of peroneal tendon pathology, but this finding has primarily been described based on cohorts with pre-existing clinical findings. Therefore, the objective of this investigation was to evaluate the frequency of apparently abnormal low-lying muscle bellies from a series of subjects without clinical or imaging findings of peroneal tendon pathology. One hundred consecutive MRIs were reviewed with measurement of the distance from the distal peroneal myotendinous junction to the tip of the fibula. This distance was observed to be 23.9 ± 8.8 mm (10.8-55.4 mm; 95% confidence interval 22.2-26.7 mm). If one assumed that a myotendinous junction within 2 cm of the distal tip of fibula represented an abnormal low-lying muscle, then we observed 37% of extremities without clinical or radiographic evidence of peroneal tendon pathology that would be considered anatomically "abnormal." When a low-lying muscle belly was defined as occurring within 2 cm of the distal tip of the fibula, then a probability analysis of our data distribution found a 32.6% probability for individuals to have an "abnormally" low-lying muscle belly. These results indicate that what has traditionally been defined intraoperatively as an abnormally low-lying peroneus brevis muscle belly might simply represent intraoperative confirmation bias of relatively normal structural anatomy.
