Abstract
BACKGROUND The aim of this study was to investigate the epidemiology of Midfoot Arthritis (MA) and Lesser toe deformity (LTD) using Weight-Bearing Computed Tomography (WBCT). METHODS 606 cases (247 male, 359 female) among 1316 consecutive cases with WBCT data from September 2014 to April 2022 were retrospectively reviewed at a single referral institution. The Cochran-Armitage test was performed to evaluate the trend of prevalence with respect to age group and obesity classification. RESULTS 139 male (56.3%) and 210 female cases (58.5%) showed MA. 157 male (63.6%) and 222 female cases (61.6%) showed LTD. 115 male (19.0%) and 157 female cases (25.9%) showed both MA and LTD. The prevalence of MA and LTD increased with age in both genders. The incidence of MA in males showed an increasing tendency until obesity class II and then was slightly decreased in obesity class III. This is contrary to females whose prevalence increased with increasing obesity groups. LTD had a similar pattern in both genders to obesity classification. CONCLUSIONS The prevalence of MA and LTD increased with age and increasing obesity groups for both genders. LEVEL OF EVIDENCE Level III, Retrospective Comparative Study.

Abstract
BACKGROUND This study examines the correction of lesser toe valgus deviation following proximal chevron metatarsal osteotomy (PCMO) and Akin osteotomy in moderate to severe hallux valgus patients, while identifying influencing factors. METHOD Among 89 patients (116 feet), those with moderate to severe hallux valgus underwent PCMO and Akin osteotomy. Radiologic assessments included preoperative metatarsus adductus angle (MAA), hallux valgus angle (HVA), intermetatarsal angle (IMA), valgus angles of the second to fourth metatarsophalangeal joints, and hallux valgus recurrence. Assessments included visual analog scale (VAS) pain scores, American Orthopaedic Foot & Ankle Society (AOFAS) scores, and patient satisfaction over an average follow-up of 30.6 ± 21.2 (range, 12-99) months. RESULTS The mean preoperative HVA of 34.4 degrees decreased to 8.7 degrees at final follow-up. The valgus angles of the second, third, and fourth toes improved by 37.1%, 27%, and 44.5%, respectively. In metatarsus adductus patients, lesser toe valgus angles were significantly higher both preoperatively and at final follow-up. Hallux valgus recurrence patients had higher preoperative and final follow-up IMA and valgus angles in the second and third toes. Nonrecurrence patients showed greater decreases in these angles. A larger HVA correction corresponded to a greater decrease in lesser toe valgus deviation. VAS and AOFAS scores improved significantly at the last follow-up. CONCLUSION The study found a significant reduction in the valgus angle of the second, third, and fourth toes after PCMO and Akin osteotomy in moderate to severe hallux valgus cases, without additional surgeries on lesser toes. The lesser toe angular reductions were less pronounced in patients with metatarsus adductus or with hallux valgus recurrence. LEVEL OF EVIDENCE Level IV, case series.

Abstract
OBJECTIVES Hallux valgus is associated with tarsometatarsal arthritis; its pathophysiology remains unknown. Therefore, we aimed to elucidate the relationship between arthritis of the second and third tarsometatarsal joints and incongruity of the first tarsometatarsal joint in the sagittal plane. METHODS Forty-three patients (64 feet) with hallux valgus who underwent surgery at University Hospital Kyoto Prefectural University of Medicine were included and divided into two groups: control (without second and third tarsometatarsal joint degeneration) and osteoarthritis (with second and third tarsometatarsal joint degeneration). Intergroup comparisons of the incongruity of the first tarsometatarsal joint in the sagittal plane, age, body mass index, hallux valgus angle, first-second intermetatarsal angle, metatarsus adductus angle, Meary's angle, and calcaneal pitch angle were performed. RESULTS The proportion of patients with incongruity of the first tarsometatarsal joint was significantly higher in the osteoarthritis group than in the control group. Logistic regression analysis identified incongruity of the first tarsometatarsal joint and metatarsus adductus angle as significant related factors for arthritis of the second and third tarsometatarsal joints. CONCLUSIONS Incongruity of the first tarsometatarsal joint in the sagittal plane was involved in the development of arthritis of the second and third tarsometatarsal joints in patients with hallux valgus.

A cross-sectional study. J Foot Ankle Res 2023; 16:90. [PMID: 38087348 PMCID: PMC10717254 DOI: 10.1186/s13047-023-00685-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2023] [Accepted: 11/14/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Floating toes are a condition and deformity in which some of the toes are afloat. Many functional impairments in floating toes have been previously studied lately and several factors related to floating toes have also been reported. However, no reports have considered the relationship between lifestyle and floating toes among children. The purpose of this study was to reveal the prevalence of floating toes among school children and reveal its relationship with lifestyle. METHODS In total, 138 young male baseball players were recruited. Lifestyle was evaluated by using a questionnaire and chosen whether the main lifestyle was Japanese or Western, if the bedding was futons or beds, and if the toilet was Japanese style (a squat toilet) or Western style. Floating toes were defined as toes that were not in contact with the mat. Ankle dorsiflexion in the knee-flexed and knee-extended positions was measured in a weight-bearing position. The relationship between the floating toes and lifestyles, and the comparison of ankle dorsiflexion range of motion between the lifestyles were statistically analyzed. RESULTS Players living in a Western style showed a significantly higher prevalence of floating toes on both feet compared with the players living in a Japanese style (throwing side; 39% vs. 19%, p = 0.04, and non-throwing side; 43% vs. 19%, p = 0.01). Players living in a Western style with beds showed a significantly smaller range of motion on both sides of ankle dorsiflexion in the knee-flexed position compared with those who were not (throwing side; 37.2 ± 5.7° vs. 39.0 ± 6.6°, p = 0.04, and non-throwing side; 36.8 ± 5.8° vs. 38.6 ± 6.1°, p = 0.04). CONCLUSION Children mainly living in a Western lifestyle showed a significantly higher prevalence of floating toes on both feet compared to those mainly living in a Japanese lifestyle. The prevalence of floating toes may be related to lifestyles among children. TRIAL REGISTRATION The study was approved by the institutional review board of the Waseda University Graduate School of Sport Sciences (IRB number 2021-185).

Abstract
Although hammertoe (HT) is a common complaint among foot patients, there is little consensus on the best surgical approach for correction. These authors hypothesized that the use of a headless intramedullary screw across both the proximal interphalangeal joint (PIPJ) and distal interphalangeal joint (DIPJ) would decrease many post-surgical complications, such as infection, pain, and mallet toe deformity, found in traditional HT corrective surgical techniques. In this retrospective cohort study, N = 163 adult patients who had undergone DIPJ/PIPJ arthrodesis for HT correction at least 1 year prior to the study were identified. One hundred fifty-nine patients were contacted through REDCap to complete Patient-Reported Outcome Measurement Information System (PROMIS) physical function (PF) and pain interference (PI). Demographic, radiographic, and follow-up data were taken from the electronic medical record (EMR). Analysis was completed with Microsoft Excel; PROMIS PF and PI measures for the 32-person cohort were 45.65 ± 8.26 and 51.65 ± 9.01, respectively. The PF and PI measures had a statistically significant correlation (R2 = 0.71). The 163-person cohort had an overall revision rate of 6.75%, or 11 patients, and an infection rate of 1.23%. This procedure had lower rates of residual pain, infection, mallet toe deformity, and reoperation when compared with current techniques. This study supports the safety and viability of PIPJ/DIPJ arthrodesis using a headless screw for HT correction.Levels of Evidence: Level III Retrospective Cohort Study.

Abstract
BACKGROUND Surgical correction of hammertoe deformities with arthrodesis of the proximal interphalangeal joint (PIP) is one of the most frequent forefoot procedures. Recently, new intramedullary fixation devices for PIP arthrodesis have been introduced. The aim of this study was to compare a newly developed absorbable intramedullary implant made of magnesium (mm.PIP), an already available intramedullary implant made of titanium (PipTree), and the classical Kirschner-wire (K-wire). METHODS The three intramedullary devices (mm.PIP, PipTree, and K-wire) for PIP arthrodesis were compared. A classical arthrodesis of the PIP joint was performed on fifty-four composite synthetic bone pairs. After arthrodesis, torsional load, weight-bearing and cyclic load tests were performed, and stability of the synthetic bone pairs was analyzed. RESULTS The mm.PIP was the most torsion resistant (mm.PIP vs. PipTree and K-wire, p < 0.001). The PipTree showed the best overall stability during cyclic weight-bearing simulation (PipTree vs. mm.PIP and K-wire, p < 0.001). K-wire demonstrated the highest breaking loads during bending tests (K-wire vs. mm-PIP and PipTree, p < 0.001). CONCLUSION Biomechanical properties of two new intramedullar implants, the bioresorbable mm.PIP made of magnesium and the PipTree made of titanium, were found to be comparable to the biomechanical properties of a K-wire which is commonly used for this procedure. Future work should be directed towards a clinical assessment of the bioabsorbable fixation devices for hammertoe procedures.

Abstract
BACKGROUND The aim of this study was to present and evaluate methods of measuring toe joint angels using joint-surface based and inertial axes approaches. METHODS Nine scans of one frozen human cadaveric foot were obtained using weight-bearing CT. Two observers independently segmented bones in the forefoot and measured metatarsalphalangeal joint (MTPJ) angles, proximal and distal interphalangeal joint (PIPJ and DIPJ) angles and interphalangeal angles of the hallux (IPJ) using 1) inertial axes, representing the long anatomical axes, of the bones and 2) axes determined using centroids of articular joint surfaces. RESULTS The standard deviations (SD) of the IPJ/PIPJ and DIPJ angles were lower using joint-surface based axes (between 1.5˚ and 4.1˚) than when the inertial axes method was used (between 3.3˚ and 16.4˚), for MTPJ the SD's were similar for both methods (between 0.5˚ and 2.6˚). For the IPJ/PIPJ and DIPJ angles, the width of the 95% CI and the range were also lower using the joint-surface axes method (95% CI: 2.0˚-4.1˚ vs 3.2˚-16.3˚; range: 3.1˚-7.4˚ vs 3.8˚-35.8˚). Intra-class correlation coefficients (ICC) representing inter- and intra-rater reliability were good to excellent regarding the MTPJ and IPJ/PIPJ angles in both techniques (between 0.85 and 0.99). For DIPJ angles, ICC's were good for the inertial axes method (0.78 and 0.79) and moderate for the joint-surface axes method (0.60 and 0.70). CONCLUSION The joint-surface axes method enables reliable and reproducible measurements of MTPJ, IPJ/PIPJ and DIPJ angles. For PIPJ and DIPJ angles this method is preferable over the use of inertial axes.

Abstract
Background First described by Soule in 1910, arthrodesis of the proximal interphalangeal joint is a common operative method of treatment of hammer toe, or fixed-flexion deformity of the proximal interphalangeal joint of the lesser toes1. The deformity is often caused by imbalance in intrinsic and extrinsic muscle function across the interphalangeal joint and metatarsophalangeal joint2,3, which can be effectively addressed through proximal interphalangeal joint straightening and arthrodesis in conjunction with soft-tissue balancing of the metatarsophalangeal joint. Description Following longitudinal skin incision over the joint, a transverse extensor tenotomy and capsulotomy reveal the proximal interphalangeal joint and provide appropriate exposure of the head of the proximal phalanx. With the soft tissues protected, the proximal and middle phalanges undergo resection of the articular surfaces to allow osseous apposition. This step can be performed with a rongeur sagittal saw or with osteotomes4,5. The head of the proximal phalanx is resected proximal to the head-neck junction, and the proximal portion of the middle phalanx is removed to expose the subchondral bone. Often, there is a dorsal contracture of the metatarsophalangeal joint that is elevating the toe, which is addressed with use of a longitudinal incision over the metatarsophalangeal joint, a Z-lengthening of the long extensor tendon to the toe, and a subsequent capsulectomy. If there is an angular component to the deformity, the collateral ligaments are released from the metatarsal neck, and the toe can be balanced. If there is residual subluxation of the joint that is incompletely corrected by soft-tissue procedures, a metatarsal osteotomy should be considered. Fixation is then performed with use of a smooth Kirschner wire. The wire is inserted from the middle phalanx out the tip of the toe and subsequently inserted retrograde across the proximal interphalangeal joint, often into the metatarsal head and neck, holding the metatarsophalangeal joint in appropriate position. This step can also be completed with use of novel methods including screws, bioabsorbable pins, or intramedullary implants6-8. Alternatives Nonoperative treatments for hammer toe deformity are generally pursued prior to surgery and include shoe modifications such as a wide toe-box, soft uppers, and padding of osseous prominences3,9,10. Alternative surgical treatments include proximal interphalangeal arthroplasty, soft-tissue capsulotomy, extensor tendon lengthening, and amputation11. Rationale Although nonoperative treatment can alleviate symptoms temporarily, surgical treatment is often necessary for definitive treatment of hammer toe. Soft-tissue procedures such as tendon lengthening can provide a stabilizing benefit, but the degenerative bone changes associated with hammer toe are better addressed with use of resection of the proximal interphalangeal joint3. Arthroplasty allows for some retained motion; however, this motion may lead to deformity and pain over time2. Arthrodesis provides less painful and more reliable fixation as well as equal outcomes compared with other operative techniques. Patient satisfaction rates after this procedure are high, with pain relief in up to 92% of patients and rare complications7-12. Expected Outcomes Outcomes of this procedure are favorable, with rates of osseous fusion ranging from 83% to 98%2,4,11,13. Patient satisfaction rates range from 83% to 100%4,11. Historically, patients have expressed dissatisfaction with pain and the appearance of exposed hardware, but novel internal fixative devices provide a more natural appearance to the toe without the need for secondary surgical procedures for pin removal8,14. Patients are often able to return to regular activity at 6 weeks postoperatively; however, there may be persistent pain or swelling in the toe. Wide shoes and activity modifications are frequently continued for several more weeks postoperatively, and some patients may benefit from formal physical therapy and at-home rehabilitation. Important Tips Avoid vascular compromise by ensuring adequate resection of bone at the proximal interphalangeal joint.A longitudinal incision across the joint provides greater exposure but can lead to scar contracture that elevates the toe. One alternative is the use of an elliptically shaped incision over the proximal interphalangeal joint, which can improve cosmesis but does restrict exposure.Excessive osseous resection can lead to a cosmetically undesirable short toe.If using an implant for the arthrodesis, ensure the implant is not too big for the toe. Most implants are too big for fifth-toe arthrodesis.In toes with severe deformity, fixation with a Kirschner wire is often preferred because excessive stretching of the neurovascular bundle can lead to toe compromise and if Kirschner wire is used the pin can easily be removed at bedside.For flexible deformities, a nonoperative approach is recommended, such as stretching exercises, shoe-wear modifications, and metatarsal pads. A tenotomy of the flexor digitorum brevis is a soft-tissue procedure that can be considered if nonoperative treatment is insufficient to correct the deformity. If flexor digitorum brevis tenotomy does not adequately treat proximal interphalangeal joint deformity, a proximal interphalangeal joint arthrodesis should be the next step.

Abstract
BACKGROUND The plantar plate is a major stabilizing structure of the metatarsophalangeal (MTP) joint with instability frequently occurring after a tear or attenuation of this structure. Commonly, a McGlamry elevator is used to strip the plantar plate from the plantar surface of the metatarsal to improve exposure of the MTP joint. The anatomy of the proximal plantar plate and vascular consequence of stripping the plantar plate from the metatarsal is not yet well understood. The purpose of this study is to describe the proximal attachment of the plantar plate anatomically and quantify the relative contribution of blood supply to the proximal plantar plate from both the metatarsal and the plantar fascia. METHODS For anatomic evaluation, 6 lower extremity cadaver specimens without any gross evidence of foot and ankle deformity were utilized. For imaging analysis, 16 fresh frozen human adult cadaveric lower extremity specimens were used for this study, resulting in 35 MTP joints without deformity and 11 lesser MTP joints with cockup and/or crossover deformities. The specimens were prepared as described previously by Finney et al.5. RESULTS From gross anatomic dissection, the plantar plate origin consists of a stout fibrous pedicle distinct from the surrounding synovial-type tissue that firmly anchors the plantar plate to the metatarsal. Based on nano-computed tomographic imaging, an average of 63.5% of the vascular supply to the proximal portion of the plantar plate entered from the metatarsal pedicle. The remaining 36.5% of the vascular supply entered from the plantar fascia. CONCLUSION The proximal attachment of the plantar plate includes a stout fibrous pedicle anchoring the proximal portion of the plantar plate to the notch between the medial and lateral plantar condyles of the metatarsal head. The vascular supply of the proximal plantar plate is supplied from both the metatarsal pedicle and plantar fascia. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Objective To compare bone healing time in osteotomies performed in claw toes correction through minimal invasive surgery in diabetic vs. non-diabetic patients. The relation between the patient's ages and the American Orthopedic Foot and Ankle Surgery Society (AOFAS) functional scores before and after surgery was also analyze in the two types of patients. Method A series of 45 women, 23 of them suffering from Diabetes Mellitus, were operated to correct claw toes. The surgery was always performed through minimal invasive digital osteotomies. After the intervention, bone healing was controlled by a fluoroscopic weekly follow-up until a complete bone consolidation was reached. Bone healing time was compared in in two groups of patients, diabetic and non-diabetic. All patients were evaluated with AOFAS scale 48 h before and 90 days after the intervention. Results The time of bone healing ranged from 24 to 40 days after the surgery and took shorter time of consolidation in non-diabetic patients although the Mann Withney U test did not show statistically significant differences (p = 0,409, effect size (ES) = 0,14 [-0.20 to 0.45]) between both groups. A statistically significant association (r = 0.71, R 2 = 50%, p < 0.001) was found between the healing days and the day of medical discharge, also between the ages of the patients and the medial discharge (r = 0.36, R 2 = 13%, p < 0.001). However, no statistically significant associations were found between pre-intervention glycemia and days of bone consolidation, neither in medical discharge (r = 0.07, p = 0.646 y r = 0.07, p = 0.648, respectively). AOFAS test scores and the diabetes status showed statistically significant differences, both in the main effect of Diabetes (F[1,41] = 9.41, p = 0.004) as in the interaction between diabetes and age (F[1,41] = 9.17, p = 0.004). Conclusions The bone healing time in claw toes operated through minimal invasive osteotomy surgery is not influenced by the presence of diabetes. The consolidation speed and the improvement in AOFAS functional scale score post-surgery in diabetic and elder patients was related to duration of the medical discharge.

Abstract
CASE A 7-year-old girl presented with a recurrent hammertoe deformity causing pain with shoe wearing after a prior corrective surgery. Surgical revision required a unique approach that included a staged corrective osteotomy of the proximal phalanx because of hypoperfusion management and the application of a rotational skin flap previously described for camptodactyly correction in the hand to avoid harvesting a skin graft. CONCLUSION Revision surgery for recurrent pediatric hammertoe deformity requires a heightened awareness of the risk for toe hypoperfusion and subsequent wound closure challenges.

Abstract
Background and aims Digital deformity in flexion, varismus (external rotation), and adduction with the toe in both supraduction and infraduction are called clinocampodactyly or curly toe. All adult patients with symptoms and a diagnosis of semirigid/rigid curly toes underwent radiological examination to verify the presence of a trapezoidal phalanx. The purpose of this study was to quantitatively determine the degrees of improvement of a dysmetric phalanx after incomplete phalangeal osteotomy using minimally invasive surgery. The points of improvement were determined using the American Orthopedic Foot and Ankle Society (AOFAS) scale score. Methods Between May 2021 and June 2022, 30 patients diagnosed with curly toes underwent unicortical osteotomy of the affected phalanx. The convergence angle was measured and the AOFAS scale scores were compared. Results A total of 33 toes underwent surgery. The average reduction of the convergence angle was 9°. The average improvement in the AOFAS scale score was 53 points at 6 months and reached almost 90 points (89.9 ± 6.1 points). Conclusions Incomplete phalangeal osteotomy performed with minimally invasive surgery of the trapezoidal phalanges of curly toes of adults can improve alignment and AOFAS scale scores.

Abstract
In this technical report study, we describe the use of a flexor tenodesis procedure in the treatment of lesser toe deformities (LTD). Using a specific implant, both the flexor digitorum longus and brevis tendons are attached to the plantar aspect of the proximal phalanx, allowing dynamic correction of flexible deformities of metatarsophalangeal and interphalangeal joints. Good clinical results and absence of complications were observed in a series of 3 patients, with considerable correction of the LTD, and absence of substantial residual floating toe or metatarsophalangeal joint stiffness.

Abstract
Background. Patients’ dissatisfaction with the results of surgical correction of lesser toes deformities, the shortcomings of methods aimed at eliminating the lateral deviation of the toe in the metatarsophalangeal joint necessitated the development of a new surgical method.The aim. To evaluate short-term results of the new surgical method for the treatment of patients with lesser toes deformity, accompanied with deviation of the toe.Materials and methods. A method of surgical treatment of deviated deformity of the small toes is proposed. The method includes precise marking of the metatarsal osteotomy line according to the previously calculated parameters of optimal shortening and displacement of the metatarsal bone, performing oblique diaphyseal osteotomy of the metatarsal bone, displacing its distal part along the osteotomy plane. According to the proposed method, nine patients were operated on who had a syndrome of nonrigid hammer-like deformity of the second toe with lateral deviation of the toe in the metatarsophalangeal joint. In all patients, the deformity of the second toe was associated with hallux valgus.Results. As a result of the application of the proposed method, it was possible to achieve deformity correction, eliminate the lateral deviation of the second toe in the metatarsophalangeal joint, restore congruence in the joint, achieve consolidation of bone fragments without loss of correction, and improve the appearance and function of the foot. Three months after the operation, a statistically significant improvement was determined, according to the AOFAS LMIS scale, having reached 94.5 ± 4.64 points, which made it possible to speak about the achievement of a good functional result of treatment. Patients noted the opportunity to wear standard footwear, to carry out their labor activity, to engage in physical culture, were satisfied with the result.Conclusion. The use of the proposed new surgical method for deflected deformity of the lesser toes makes it possible to correct the deformity, eliminate lateral deviation of the toe, relieve pain syndrome, achieve a good cosmetic and functional result, restoring the patients’ ability to wear standard shoes.

Abstract
ZusammenfassungDie Therapie des rheumatischen Fußes ist komplex und erstreckt sich
über ein breites Spektrum von konservativen und operativen
Behandlungsmethoden. Das Ziel ist, bei guter Stabilität,
möglichst viel Beweglichkeit zu erhalten. Nebenerkrankungen wie die
Polyneuropathie mit und ohne Diabetes mellitus beeinflussen die
Behandlungsoptionen entscheidend. Aufgrund dessen, dass beim Rheumatiker
multiple Gelenke befallen sind, unterliegen die orthopädische
Schuhversorgung und die operative Therapie des rheumatischen Fußes
speziellen Anforderungen im Hinblick auf das Gewicht, die Stabilität des
Schuhs und Bettung des Fußes bzw. die Zugangswege und die
Primärstabilität der Osteosynthesen. Der aufrechte Gang kann
durch einen stadiengerechten zielgerichteten Einsatz aller Therapieoption sehr
lange erhalten bleiben. Hierfür müssen die therapeutischen
Fenster erkannt und genutzt sowie eine Übertherapie vermieden

Abstract
Toe hypoperfusion is a commonly encountered concern following forefoot surgery, yet there is limited clinical guidance available to surgeons to aid in management of this scenario. This work aims to review the etiology, pathophysiology and current strategies to address a perioperative ischemic toe. The authors review various interventions to approach this problem based on available evidence and clinical experience. Interventions to restore perfusion can be loosely based on the ischemic causality they intend to address. Described maneuvers to restore perfusion have, in turn, been designed to either chemically (through topical/local medication) or mechanically (bending/removing K-wires, adjusting repair tension) aid in mitigation of the offending cause. Depending upon the type of surgery performed, which may or may not include instrumentation, a surgeon can implement a series of steps to maximize restoration of toe perfusion. LEVEL OF EVIDENCE: V.

Abstract
Hammertoe deformity correction surgery is one of the most common procedures performed by foot and ankle surgeons. Recent foot and ankle medical literature presents conflicting opinions regarding the optimal intramedullary fixation device and techniques for use in digital deformity correction. There are a number of varying fixation constructs of intramedullary Kirschner wire fixation reported for proximal interphalangeal joint arthrodesis; however, there are no reports of relative loading strength of the fixations. In this study, 90 sawbone models were divided equally into 3 groups of different intramedullary Kirschner wire fixation techniques: Group A- single straight, Group B- single bent, Group C- double bent. Each fixation construct underwent controlled axial loading and failure points were observed. Results showed no significant difference in load failure from all 3 groups with mean maximum force of Group A = 20N, Group B = 19.1N, and Group C =17.5N. We conclude that all Kirschner wire fixation options for digital deformity correction, will provide similar resistance to sagittal plane axial loads.

Abstract
Background and Objectives: Hammertoe, one of the most common toe deformities, causes pain due to overloading of the periarticular tissues and skin lesions. Additionally, it results in problems with footwear choice, an unattractive foot appearance and a deterioration in quality of life. The most common treatment for rigid and advanced deformities is surgery, and these procedures are widely described in literature. If the changes in the interphalangeal and metatarsophalangeal joints are flexible (that mean they undergo correction without causing pain) or surgery is not possible, conservative treatment should be considered. No research, however, has been found detailing this treatment method. Conservative treatment includes the Kinesiology Taping (KT) method, which involves applying taping to correct deformities. This report describes the effect of KT treatment in a female patient with hammertoes. Materials and Methods: Anthropometric foot measurements (3D scanner) and foot loadings (baropodometric platform) are presented before KT applying, immediately after tapes application and after tapes removal following one month of use. Results: After using KT application parameters such as: foot length, maximum foot load, load under the area of the metatarsals II-III changed. Conclusion: Kinesiology Taping seems to be a symptomatic form of treatment of the effects of lesser toes deformity, therefore it is a good alternative for patients who do not want or cannot undergo surgery.

Abstract
BACKGROUND Recent surgical techniques have focused on anatomic repair of lesser toe metatarsophalangeal (MTP) plantar plate tears, yet it remains unknown whether the plantar plate has the biological capacity to heal these repairs. Therefore, a better understanding of the plantar plate vasculature in response to injury may provide further insight into the potential for healing after anatomic plantar plate repair. Recently, a study demonstrated that the microvasculature of the normal plantar plate is densest at the proximal and distal attachments. The purpose of this study was to compare the intact plantar plate microvasculature network to the microvasculature network of plantar plates in the presence of toe deformity using similar perfusion and nano-computed tomographic (CT) imaging methods. METHODS Seven fresh-frozen human cadaveric lower extremities with lesser toe deformities including hammertoe or crossover toe were perfused using a barium solution. The soft tissues of each foot were counterstained with phosphomolybdic acid (PMA). Then using nano-CT imaging, the second through fourth toe metatarsophalangeal joints of 7 feet were imaged. These images were then reconstructed, plantar plate tears were identified, and 11 toes remained. The plantar plate microvasculature for these 11 toes was analyzed, and calculation of vascular density along the plantar plate was performed. Using analysis of variance (ANOVA), this experimental group was compared to a control group of 35 toes from cadaveric feet without deformity and the vascular density compared between quartiles of plantar plate length proximal to distal. A power analysis was performed, determining that 11 experimental toes and 35 control toes would be adequate to provide 80% power with an alpha of 0.05. RESULTS Significantly greater vascular density (vascular volume/tissue volume) was found along the entire length of the plantar plate for the torn plantar plates compared to intact plantar plates (ANOVA, P < .001). For the first quartile of length (proximal to distal), the vascular density for the torn plantar plates was 0.365 (SD 0.058) compared to 0.281 (SD 0.036) for intact plantar plates; in the second quartile it was 0.300 (SD 0.044) vs 0.175 (SD 0.025); third quartile it was 0.326 (SD 0.051) vs 0.117 (SD 0.015); and fourth (most distal) quartile was 0.600 (SD 0.183) vs 0.319 (SD 0.082). CONCLUSION Torn plantar plates showed increased vascular density throughout the length of the plantar plate with an increase in density most notable in the region at or just proximal to the attachment to the proximal phalanx. Our analysis revealed that torn plantar plates exhibit neovascularization around the site of a plantar plate tear that does not exist in normal plantar plates. CLINICAL RELEVANCE The clinical significance of the increased vascularity of torn plantar plates is unknown at this time. However, the increase in vasculature may suggest that the plantar plate is a structure that is attempting to heal.

Abstract
PURPOSE Selective percutaneous tenotomy of the flexor digitorum longus (FDL) is a treatment for claw toes that gives astonishingly good functional results despite tendon sacrifice. However, the involution of the FDL tendon stump after tenotomy is unknown. The aim of our study was to assess the involution of the tendon stump after selective percutaneous tenotomy of the FDL. METHODS The study included two parts. In the clinical part, an ultrasound analysis of 15 FDL tenotomies in 7 patients was carried out 3 months post-surgery. In the anatomic part, the feet of 10 bodies donated to science were dissected and examined anatomically. RESULTS The proximal stump of the FDL was located near the base of the proximal phalanx and moved synchronously with the flexor digitorum brevis (FDB).Separating the FDB and FDL revealed a large tissue connection between the plantar surface of the tendinous chiasm of the FDB and the dorsal part of the FDL. These connections had significant resistance ranging from 2 to 9 Newtons depending on the toe. Tenotomy of the FDL followed by proximal traction of it led to retraction of the stump up to the base of the proximal phalanx and transfer of its action to the FDB by tensioning the intertendinous structure. Histologically, these structures were mostly comprised of tendon connective tissue. Their vascular component was small. CONCLUSION The presence of this intertendinous connection leads, in the case of isolated tenotomy of the FDL, to equivalent transfer of the latter to the FDB.

[PMID: 32173282 DOI: 10.1016/j.fas.2020.02.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2019] [Revised: 10/16/2019] [Accepted: 02/06/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND Curly toe deformity is a relatively common deformity that generally occurs at the 4th and 5th proximal and/or middle phalanges but rarely presents with symptoms. Although numerous open operative techniques have been introduced, there is no established treatment yet. We report the results of minimally invasive correction for symptomatic, fixed curly toe deformity. METHODS Between 2016 and 2018, 25 consecutive percutaneous dorsolateral closing wedge-shaped osteotomies with Shannon burrs at the proximal and/or middle phalanx were performed. We assessed the postoperative clinical and radiological changes at a mean of 22.51 months of follow-up. RESULTS The locations of osteotomy were at the middle phalanx in 10 cases, proximal phalanx in 13 cases, and both in one case. The mean amount of corrections of varus inclination and shortening were 16.54° and 2.24 mm, respectively. The Foot and Ankle Ability Measure Activities of Daily Living scores significantly improved from 59.09 preoperatively to 74.55 at the last follow-up. There was one case of pin site infection and one case of incision site numbness due to digital nerve injury. CONCLUSIONS Minimally invasive dorsolateral closing wedge-shape osteotomy is a simple, safe, and effective correction for symptomatic, fixed curly toe deformity.

Abstract
Intramedullary devices have been developed to reduce the problems associated with Kirschner (K)-wire fixation in proximal interphalangeal joint (PIPJ) arthrodesis. The purpose of this systematic review is to compare the surgical outcomes of K-wires versus novel internal fixation devices in PIPJ arthrodesis in claw/hammer toe surgery. The databases searched were PubMed, Scopus, Cochrane, and Embase with keywords "claw toe OR hammer toe" AND "proximal interphalangeal OR PIP" AND "fusion OR arthrodesis." Clinical trials published in English with evidence levels I, II, and III were included. Five studies, including one randomized controlled trial and four case-controlled studies, were identified to meet the inclusion criteria. Overall, the studies showed promising results in union rates using the novel internal devices compared to K-wires. However, the novel internal devices seem not to present advantages in clinical parameters such as pain levels, patient satisfaction, foot-related function, or surgical complication rates.

Abstract
BACKGROUND Crossover second toe is often presented in moderate to severe hallux valgus. However, its clinical impact on the postoperative outcome of hallux valgus is still unknown. METHODS Thirty-five patients who had moderate to severe hallux valgus with crossover second toe were matched with 35 controls who did not have crossover second toe, according to preoperative hallux valgus angle and first-second intermetatarsal angle. Radiological parameters, Foot Function Index (FFI), and Visual Analog Scale (VAS) were assessed as postoperative outcomes at 3, 6, and 12 months after surgery. RESULTS At 3 months, the FFI in the crossover second toe group was lower than in the control group (p=0.001), while other outcomes were similar. On the other hand, there were no significant differences between the groups at 6 and 12 months, in terms of radiological parameters, FFI, and VAS. CONCLUSIONS Patients who had moderate to severe hallux valgus with crossover second toe were at risk for slow functional recovery after surgical treatment in the short term, but, in the long-term, there was no difference in overall postoperative outcomes in patients with and without crossover second toe. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Background: A novel biointegrative implant was developed for proximal interphalangeal joint (PIPJ) arthrodesis to treat hammertoe deformity. Composed of continuous reinforcing mineral fibers bound by bioabsorbable polymer matrix, the implant demonstrated quiescent, gradual degradation with complete elimination at 104 weeks in animal models. This prospective trial assessed the implant’s safety, clinical performance, and fusion rate of PIPJ arthrodesis for hammertoe correction. Methods: Twenty-five patients (mean age 63.9±7.5 years) who required PIPJ arthrodesis were enrolled at 3 centers. Outcomes included radiographic joint fusion, adverse events, pain visual analog scale (VAS) score, Foot and Ankle Ability Measure (FAAM) Activities of Daily Living (ADL) score, and patient satisfaction. Patients were evaluated 2, 4, 6, 12, and 26 weeks postoperatively. Results: Twenty-two patients (88%) achieved radiographic fusion at 26 weeks. All joints (100%) were considered clinically stable, with no complications or serious adverse events. Pain VAS improved from 5.3±2.5 preoperatively to 0.5±1.4 at 26 weeks postoperatively. FAAM-ADL total scores and level of functioning improved by mean 19.5±19.0 points and 24.4±15.7 percentage points, respectively, from preoperation to 26 weeks postoperation. Improvements in pain VAS and FAAM scores surpassed established minimal clinically important differences. All patients were very satisfied (84%) or satisfied (16%) with the surgery. Patient-reported postoperative results greatly exceeded (72%), exceeded (20%), or matched (8%) expectations. Conclusion: This prospective, multicenter, first-in-human clinical trial of a novel biointegrative fiber-reinforced implant in PIPJ arthrodesis of hammertoe deformity demonstrated a favorable rate of radiographic fusion at 12 and 26 weeks, with no complications and good patient-reported clinical outcomes. Level of Evidence: Level IV, prospective case series.

Abstract
"Splay toe" is a rare deformity of the forefoot and often causes the occurrence of metatarsalgia and dysfunction while walking or weight bearing. Since it involves a deviation in the sagittal and transversal planes, often combined with a malrotation, surgical correction can be challenging. We describe a case of splay toe deformity in the forefoot causing metatarsalgia in a 62-year-old female patient with a former avascular osteonecrosis of the 2 metatarsal head Smillie stage V of Freiberg-Köhler's disease causing a splay toe between the 2nd and the 3rd rays. There are only few reports in the literature, and a clear treatment strategy has not been defined, yet, although, it has been described that most of these patients are operated more than once. In the presented case, we performed a successful treatment by a combined surgical technique consisting in modified Weil's osteotomy and the transfer of the extensor brevis tendon. We sustain that for correction of a multiplanar deformity of lesser toe deformities osseous correction as well as tendon transfer lead to successful therapy.

Abstract
Minimally invasive procedures to treat lesser toes deformities are among the main surgeries of percutaneous techniques and considered mature techniques due to technical versatility and high correction potential, with low rates of complications. Although they seem technically simple procedures, there are important technical details for each of them to obtain a reliable correction. To achieve success in lesser toes percutaneous treatment, it is imperative to follow minimally invasive basic principles, especially postoperative care with specific bandages for unfixed osteotomies. Practical training is mandatory before starting the experience; the foot surgeon must learn theoretic and practical aspects to master this surgery.

Abstract
BACKGROUND The French Association of Foot Surgery (AFCP) recently proposed a morphological classification of lesser toe deformities, describing the position of each joint (metatarsophalangeal or MTP, proximal interphalangeal or PIP and distal interphalangeal or DIP) in relation to their anatomic position in the sagittal plane. A study was designed to test its reliability for assessment of sagittal plane deformities of the second toe. METHODS In this retrospective study 55 toes (55 feet, 50 patients) were evaluated. Eleven foot and ankle surgeons assessed independently standardized photographs of each case acquired in a blinded fashion. Assessment was repeated three times, each 15 days apart. Intra- (Intraclass Correlation Coefficient or ICC) and inter-observer reliability (Fleiss' Kappa coefficient) were calculated for each joint. RESULTS Intra- and inter-observer reliability were moderate for the MTP joint (ICC range, 0.54-0.61) (Kappa range, 0.53-0.61) and substantial for the PIP (ICC range, 0.60-0.71) (Kappa range, 0.68-0.75) and DIP joints (ICC range, 0.69-0.78) (Kappa range, 0.74-0.78). Mean assessment time±standard deviation was 35±10s per case. CONCLUSIONS The AFCP classification proved itself reliable in the assessment of sagittal plane defomities of the second toe among eleven foot and ankle surgeons. It is based only on a visual description of the deformity, and does not provide informations on either the clinical reducibility of the deformity and the radiographic joint status.

Abstract
BACKGROUND Although Kirschner wire implantation is popular for treating toe deformities, complications frequently occur. To prevent pin-tract infection and difficult Kirschner wire extraction, several implants have been developed to improve treatment outcomes. METHODS Patients who had undergone an interphalangeal fusion by two-component implant for the treatment of toe deformities were included. Thirty-one toes of 21 patients were evaluated retrospectively. American Orthopaedic Foot and Ankle Society (AOFAS) forefoot scores were used in clinical evaluation. RESULTS The mean operation duration per toe was 16.4 min (range, 13-26 min). The average AOFAS forefoot score was 42.76 (range, 23-57) preoperatively and 88.76 (range, 70-95) at 34.4 months (range, 26-46 months) after surgery. Mean follow-up was 14.8 months (range, 12-19 months). Compared with before surgery, the AOFAS score was increased significantly after surgery (P = .03 by t test). Three minor complications were encountered. In one patient an infection was observed. After the implants were removed (first month) she was treated successfully by debridement and antibiotic agents and, finally, Kirschner wire placement. The second patient had a fissure fracture at the proximal phalanx, but routine follow-up did not change. In the third patient, the locking mechanism had become loose (detected on day 1 radiography); it was remounted under fluoroscopy without opening the wound. No patients had a cutout, loss of alignment, recurrence, or persistent swelling. CONCLUSIONS Outcomes of arthrodesis using the two-component implant were found to be safe and reliable, especially for hammer toe and fifth toe deformities.

Abstract
BACKGROUND Hallux valgus and lesser toe deformities are common foot disorders with substantial functional consequences. While the exact etiologies are multi-factorial, it is unknown if certain endocrine abnormalities, such as thyroid dysfunction, may be associated with these pathologies. The current study sought to investigate the prevalence of thyroid disease in patients with hallux valgus or lesser toe deformities. METHODS Every new patient who presented to our institution's foot and ankle clinic during a three-month time period was given a survey to determine the presence of a known thyroid disorder. The diagnosis for each visit was then recorded. Additionally, a national, publicly available database was queried for patients diagnosed with thyroid disease and concomitant hallux valgus or specific forefoot pathology. Odds ratios for the presence of thyroid dysfunction were then calculated for each patient group. RESULTS Three-hundred and fifty initial visit patient surveys were collected, and 74 (21.1%) patients had a known diagnosis of thyroid disease. The most common diagnoses were primary hypothyroidism (n = 61, 17.4%), secondary hypothyroidism (n = 6, 1.7%), thyroiditis (n = 4, 1.1%), and hyperthyroidism (n = 3, 0.9%). Thyroid disease was present in 16 of 26 patients (61.5%) with a diagnosis of hallux valgus (OR 7.3, CI[3.16-16.99], p < 0.0001). Lesser toe deformities, including hammertoes, mallet toes, bunionettes and crossover toes, were also significantly associated with thyroid disease (OR 5.45, CI[1.83-16.26], p < 0.002). The national database revealed 905,924 patients with a diagnosis of a specific forefoot deformity, and 321,656 of these patients (35.5%) had a concomitant diagnosis of a thyroid condition (OR 2.11, CI[2.10-2.12], p < 0.0001). CONCLUSIONS The current study suggests a significant association between forefoot pathology and thyroid dysfunction, especially hallux valgus and lesser toe deformities. Increased understanding of these correlations may offer an important opportunity in population health management, both in diagnosis and treatment. While further studies with long-term outcomes are necessary, the early diagnosis of thyroid disease may provide an opportunity to predict and potentially alter the course of forefoot pathology.

Abstract
BACKGROUND Hammertoe correction is perhaps the most common elective surgery performed in the foot, yet rates of symptomatic recurrence and revision surgery can be high. In this study, we aimed to identify patient and provider risk factors associated with failure after hammertoe surgery. METHODS Consecutive patients with a minimum of 6 months' follow-up undergoing hammertoe surgery within a single, urban foot and ankle practice between January 1, 2011, and December 31, 2013, served as the basis of this retrospective cohort study. Cox regression analysis was used to identify important predictor variables obtained through chart and radiographic review. One hundred fifty-two patients (311 toes) with a mean age of 60.8 ± 11.2 years and mean follow-up of 29.5 ± 21.2 months were included. RESULTS Statistically significant predictors of failure were having a larger preoperative transverse plane deviation of the digit (hazard ratio [HR], 1.03 for each degree; P < .001; 95% CI, 1.02, 1.04), operating on the second toe (vs third or fourth) (HR, 2.23; P = .003; 95% CI, 1.31, 3.81), use of a phalangeal osteotomy to reduce the proximal interphalangeal (PIP) joint (HR, 2.77; P = .005; 95% CI, 1.36, 5.64), and using less common/conventional operative techniques to reduce the PIP joint (HR, 2.62; P = .03; 95% CI, 1.09, 6.26). Concomitant performance of first ray surgery reduced hammertoe recurrence by 50% (HR, 0.51; P = .01; 95% CI, 0.30, 0.87). CONCLUSION We identified risk factors that may provide guidance for surgeons during preoperative hammertoe surgery consultations. This information may better equip patients with appropriate postoperative expectations when contemplating surgery. LEVEL OF EVIDENCE Level III, retrospective case series.

Abstract
BACKGROUND The foot of a newborn is a structure that is under formation and is susceptible to presenting pathologic disorders from the moment of birth. Evidence of the prevalence of clinodactyly in newborns is scarce. Therefore, the objective of this study was to determine that prevalence and its interrelationship with gestational and neonatal factors. METHODS In a sample of 305 newborns (147 boys and 158 girls), the commonest podiatric medical alterations with either a genetic or a postural component present at the moment of birth were explored physically. The prevalence found in the sample was then related to different anthropometric, gestational, and racial/ethnic parameters of the newborn. RESULTS The sex of the newborn was unrelated to any podiatric medical pathology found. Clinodactyly was present in approximately 90% of the fifth toes studied. Breech or transverse fetal presentation and the width of the forefoot affected the appearance of clinodactyly of the fourth and fifth toes. The anthropometric differences between the feet of boys and girls were verified. CONCLUSIONS The presence of clinodactyly of the fourth and fifth toes in newborns is a frequent clinical finding and should, therefore, be considered in the podopediatric examination. In the neonatal population studied, the pathologic disorders explored did not depend on sex. The prevalence of fourth and fifth toe clinodactyly was significantly influenced by breech or transverse presentation and by forefoot width, but not by the mother's race/ethnicity.

Abstract
GENERAL PURPOSE To provide information on a 60-second General Foot Screen to assist in the prevention and/or identification and management of common foot problems. TARGET AUDIENCE This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES After participating in this educational activity, the participant should be better able to:1. Use the 60-second General Foot Screen to assist healthcare professionals in the recognition of common foot problems.2. Identify risk factors, causes, and treatment of selected foot problems. ABSTRACT Foot health is important to overall patient health. Early diagnosis and treatment of diabetes, neuropathy, fungal foot infections, foot deformity, and vascular disease/lower leg edema can improve patient quality of life. One way to achieve this is effective screening. To this end, researchers piloted a validated 10-item screening tool to assess foot health on 120 patients; 74.17% had at least one positive abnormality, demonstrating the critical importance of these early findings. Only 25.83% of individuals had completely low-risk feet. This easy-to-use tool can assist healthcare professionals in the recognition and treatment of common foot problems. The article also outlines the early signs of disease by screening item and provides a guide to treatment to enable effective prevention and quality care.

Abstract
BACKGROUND Lesser toe metatarsal head degeneration and collapse can cause significant pain and disability. In the setting of global metatarsal head collapse, there are limited operative options. The purpose of our study was to evaluate clinical and radiographic outcomes after lesser toe metatarsophalangeal (MTP) joint interpositional arthroplasty with a tendon allograft and to describe the operative technique. METHODS We retrospectively reviewed a consecutive series of patients treated by 3 fellowship-trained foot and ankle surgeons at one institution. We created a phone survey to evaluate satisfaction, pain, and likelihood to repeat the surgery. Foot and Ankle Ability Measure (FAAM) scores were reviewed before and after surgery. Preoperative and postoperative radiographs were evaluated for preservation of metatarsal length. The procedure was performed through a dorsal midline approach. The metatarsal head was reamed to a concave shape. A tendon allograft was fashioned into a ball and secured to the metatarsal with an anchor. Fifteen feet in 14 patients underwent lesser MTP joint interposition arthroplasty, with the average age of 49 years (range, 24-69), and an average follow-up of 4.2 years. RESULTS Eighty percent (12/15) reported they would have the procedure again. Visual analog scale pain scores showed a decrease in pain from 7 to 1. FAAM sports subscale improved from 56% to 85%. Radiographically, the ratio of the affected metatarsal length to the adjacent metatarsal remained constant before and after surgery, suggesting preservation of the metatarsal cascade. CONCLUSION Interpositional arthroplasty of the lesser MTP joints with a rolled tendon allograft provided a unique solution, as it allows the surgeon to fill a large void without harvesting an autograft. This study showed improved patient-reported outcomes, high patient satisfaction, and good radiographic outcomes. Lesser metatarsophalangeal joint allograft interposition arthroplasty was a viable solution as a salvage procedure in the setting of global metatarsal head collapse.

Abstract
Background: The transfer of flexor-to-extensor is widely used to correct lesser toe deformity and joint instability. The flexor digitorum longus tendon (FDLT) is percutaneously transected at the distal end and then routed dorsally to the proximal phalanx. The transected tendon must have enough mobility and length for the transfer. The purpose of this study was to dissect the distal end of FDLT and identify the optimal technique to percutaneously release FDLT. Methods: Eight fresh adult forefoot specimens were dissected to describe the relationship between the tendon and the neurovascular bundle and measure the width and length of the distal end of FDLT. Another 7 specimens were used to create the percutaneous release model and test the strength required to pull out FDLT proximally. The tendons were randomly released at the base of the distal phalanx (BDP), the space of the distal interphalangeal joint (SDIP), and the neck of the middle phalanx (NMP). Results: At the distal interphalangeal (DIP) joint, the neurovascular bundle begins to migrate toward the center of the toe and branches off toward the center of the toe belly. The distal end of FDLT can be divided into 3 parts: the distal phalanx part (DPP), the capsule part (CP), and the middle phalanx part (MPP). There was a significant difference in width and length among the 3 parts. The strength required to pull out FDLT proximally was about 168, 96, and 20 N, respectively, for BDP, SDIP, and NMP. Conclusion: The distal end of FDLT can be anatomically described at 3 locations: DPP, CP, and MPP. The tight vinculum brevis and the distal capsule are strong enough to resist proximal retraction. Percutaneous release at NMP can be performed safely and effectively. Clinical Relevance: Percutaneous release at NMP can be performed safely and effectively during flexor-to-extensor transfer.

Abstract
Lesser digit deformities that require surgical intervention may be corrected by interphalangeal arthrodesis. The traditional fixation device used to stabilize an interphalangeal arthrodesis is a smooth Kirschner wire (K-wire). Its use, however, has been associated with risks. The K-wires are known to migrate and break, and there are increased risks of pin tract infection. Choices for digital implants include nonresorbable, resorbable, and allograft. There are more than 60 newer intramedullary fixation devices available for use in digital surgery. Intramedullary implants also have their own inherent risks. Further research into patient outcomes and cost-effectiveness of these new devices is still needed.

Abstract
Forefoot disorders are often seen in clinical practice. Forefoot deformity and pain can deteriorate gait function and decrease quality of life. This review presents common forefoot disorders and conservative treatment using an insole or orthosis. Metatarsalgia is a painful foot condition affecting the metatarsal (MT) region of the foot. A MT pad, MT bar, or forefoot cushion can be used to alleviate MT pain. Hallux valgus is a deformity characterized by medial deviation of the first MT and lateral deviation of the hallux. A toe spreader, valgus splint, and bunion shield are commonly applied to patients with hallux valgus. Hallux limitus and hallux rigidus refer to painful limitations of dorsiflexion of the first metatarsophalangeal joint. A kinetic wedge foot orthosis or rocker sole can help relieve symptoms from hallux limitus or rigidus. Hammer, claw, and mallet toes are sagittal plane deformities of the lesser toes. Toe sleeve or padding can be applied over high-pressure areas in the proximal or distal interphalangeal joints or under the MT heads. An MT off-loading insole can also be used to alleviate symptoms following lesser toe deformities. Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve that leads to a painful condition affecting the MT area. The MT bar, the plantar pad, or a more cushioned insole would be useful. In addition, patients with any of the above various forefoot disorders should avoid tight-fitting or high-heeled shoes. Applying an insole or orthosis and wearing proper shoes can be beneficial for managing forefoot disorders.

Abstract
BACKGROUND: Lesser toe plantar plate attenuation or disruption is being increasingly implicated in a variety of common clinical conditions. A multitude of surgical techniques and devices have been recently developed to facilitate surgical repair of the plantar plate. However, the microvascular anatomy, and therefore the healing potential in large part, has not been defined. We investigated the microvasculature of the plantar plate by employing a novel technique involving microvascular perfusion and nano-computed tomography (nano-CT) imaging. METHODS: Twelve human adult cadaveric lower extremities were amputated distal to the knee. The anterior and posterior tibial arteries were perfused with a barium solution. The soft tissues of each foot were then counterstained with phosphomolybdic acid (PMA). The second through fourth toe metatarsophalangeal (MTP) joints of 12 feet were imaged with nano-CT at 14-micron resolution. Images were then reconstructed for analysis of the plantar plate microvasculature and calculation of the vascular density along the length of the plantar plate. RESULTS: A microvascular network extends from the surrounding soft tissues at the attachments of the plantar plate on both the metatarsal and proximal phalanx. The midsubstance of the plantar plate appears to be relatively hypovascular. Analysis of the vascular density along the length of the plantar plate demonstrated a consistent trend with increased vascular density at approximately the proximal 29% and distal 22% of the plantar plate. CONCLUSION: There is a vascular network extending from the surrounding soft tissues into the proximal and distal attachments of the plantar plate. CLINICAL RELEVANCE: The hypovascular midportion of the plantar plate may play an important role in the underlying pathoanatomy and pathophysiology of this area. These findings may have significant clinical implications for the reparative potential of this region and the surgical procedures currently described to accomplish anatomic plantar plate repair.

Abstract
The treatment of hammer toe has been advocated for years, and many procedures have been proposed with skeletal and soft tissue intervention. The purpose of the present study was to compare arthrodesis of the proximal interphalangeal joint with shortening osteotomy of the proximal phalanx neck. In most cases, both procedures have been associated with elongation of the extensor apparatus, capsulotomy of the metatarsophalangeal joint, and stabilization with a Kirschner wire. To experiment with a technique that respects the anatomy and joint function, we used a distal subtraction osteotomy of the proximal phalanx neck. We compared a series of 78 patients, divided in to 2 groups: 38 (48.7%) treated with arthrodesis and 40 (51.3%) with shortening osteotomy. Patients were aged 22 to 78 years, with a mean final follow-up period of 56.6 (range 24 to 96) months. For clinical evaluation, we used the American Orthopaedic Foot and Ankle Society score, Foot and Ankle Outcome Score, and a subjective rating scale. The results were comparable between the 2 techniques; however, we report faster functional recovery in the group treated with shortening osteotomy (p < .0001), with an adjunctive advantage of preserving the integrity of the proximal interphalangeal joint. Thus, according to our results, this technique is comparable to arthrodesis.

Abstract
Hammertoe deformities are one of the most common foot deformities, affecting up to one third of the general population. Fusion of the joint can be achieved with various devices, with the current focus on percutaneous Kirschner (K)-wire fixation or commercial intramedullary implant devices. The purpose of the present study was to determine whether surgical intervention with percutaneous K-wire fixation versus commercial intramedullary implant is more cost effective for proximal interphalangeal joint arthrodesis in hammertoe surgery. A formal cost-effectiveness analysis using a decision analytic tree model was conducted to investigate the healthcare costs and outcomes associated with either K-wire or commercial intramedullary implant fixation. The outcomes assessed included long-term costs, quality-adjusted life-years (QALYs), and incremental cost per QALY gained. Costs were evaluated from the healthcare system perspective and are expressed in U.S. dollars at a 2017 price base. Our results found that commercial implants were minimally more effective than K-wires but carried significantly higher costs. The total cost for treatment with percutaneous K-wire fixation was $5041 with an effectiveness of 0.82 QALY compared with a commercial implant cost of $6059 with an effectiveness of 0.83 QALY. The incremental cost-effectiveness ratio of commercial implants was $146,667. With an incremental cost-effectiveness ratio of >$50,000, commercial implants failed to justify their proposed benefits to outweigh their cost compared to percutaneous K-wire fixation. In conclusion, percutaneous K-wire fixation would be preferred for arthrodesis of the proximal interphalangeal joint for hammertoes from a healthcare system perspective.

Abstract
BACKGROUND Weakness of the toe flexor muscles has been attributed to the development of toe pathologies, and it responds well in the clinic to toe grip exercises. However, it is unknown whether exercising the toe flexor muscles improves the ability to grip and alter function. The aim of this study was to assess the effect of toe flexor exercises on apical plantar pressure, as a measure of grip, while seated and during gait. METHODS Twenty-three individuals with no known toe pathologies were recruited. Static peak pressure, time spent at peak pressure, and pressure-time integral while seated, as well as dynamic forefoot maximal force, contact area, and percentage contact time, were recorded before and after exercise. Toe grip exercises with a therapy ball were completed daily for 6 weeks. RESULTS Static peak pressure significantly increased after exercise on the apex of the second and third digits, as did the pressure-time integral. Dynamic peak force and contact area did not alter after exercise around the metatarsals and toes, yet percentage contact time significantly increased for each metatarsal after completing daily toe grip exercises. CONCLUSIONS Exercises to improve the grip ability of the toes increased the static peak pressure on the apex of the second and third digits as well as the percentage contact time of the metatarsals during gait. The ability to increase apical peak pressure and contact time after exercises could assist in improving forefoot stability and gait efficiency and in reducing toe pathology progression.

Abstract
BACKGROUND Lesser toe metatarsal-phalangeal (MTP) joint instability can be a major source of pain and dysfunction. Instability occurs when there is incompetence of the plantar plate and/or collateral ligaments. Newer operative treatments focus on performing anatomic repairs of the plantar plate. The goal of this study was to compare the biomechanical properties of 3 suture configurations that may be used for plantar plate repairs. METHODS Biomechanical analysis of 27 lesser toe plantar plates from fresh frozen human cadavers was completed. The plantar plate was detached from the proximal phalanx, and suture was placed in the distal plantar plate in a horizontal mattress, luggage-tag, or Mason-Allen suture configuration. Cyclic loading followed by load-to-failure testing was performed. RESULTS There was a significant difference in peak load-to-failure force between constructs (mattress: 115.53 ± 15.95 N; luggage-tag 102.42 ± 19.33 N; Mason-Allen: 89.96 ± 15.78 N; P = .015). Post hoc analysis demonstrated that the mattress configuration had significantly higher load-to-failure force compared with the Mason-Allen configuration ( P = .004). There were no significant differences between the mattress and the luggage-tag configurations or the luggage-tag and the Mason-Allen configurations. There were no differences in construct stiffness, axial displacement at the time of failure, or number of cycles required to produce 2 mm of displacement. CONCLUSION The mattress configuration demonstrated better peak load-to-failure force compared with the Mason-Allen configuration but was not statistically different from the luggage-tag configuration. Although not significant, the mattress configuration trended toward higher load-to-failure force compared with the luggage-tag. CLINICAL RELEVANCE The horizontal mattress stitch may be the biomechanically superior configuration in plantar plate repairs.

Abstract
BACKGROUND Hammertoe deformities are the most common lesser toe deformity. To date, no studies have looked at outcomes of operative management in the geriatric population, which may be at greater risk for complications or functional compromise because of comorbidities. METHODS Data on 58 patients undergoing operative correction of hammertoe deformities were prospectively collected. Clinical outcomes were assessed using preoperative and postoperative visual analogue scale (VAS) and Short Form Health Survey (SF-36) scores with a minimum of 6-month follow-up. Patients were divided into 2 groups on the basis of age at the time of surgery: younger than 65 and 65 and older. Complication rates and mean VAS and SF-36 improvement were compared. Forty-seven patients met inclusion criteria (7 men, 40 women), with 26 patients (37 toes) in the younger cohort and 21 patients (39 toes) in the older cohort. RESULTS Overall, patients demonstrated significant improvement from baseline to 6 and 12 months postoperatively in VAS ( P < .001 and P < .001) and SF-36 ( P < .001 and P < .001) scores. Mean improvement in VAS and SF-36 scores was not significantly different between the groups at 6 and 12 months postoperatively. Complications occurred in 13.5% and 10.3% of patients in the younger and older cohorts, respectively. CONCLUSIONS Outcomes of operative correction of hammertoe deformities in older patients were similar to outcomes in younger patients after greater than 6 months of follow-up. Overall improvement in VAS and SF-36 was statistically significant for both cohorts. There was no associated increase in complications for older patients.

Abstract
Hammer-toe deformities that fail nonoperative treatment can be successfully addressed with proximal interphalangeal joint resection arthroplasty or fusion. The goal of surgery is to eliminate the deformity and rigidly fix the toe in a well-aligned position. Hammer-toe correction procedures can be performed with temporary Kirschner wire (K-wire) fixation for 3 to 6 weeks with high success rates. Pain relief with successful hammer-toe correction approaches 90%; patient satisfaction rates approximate 84%. Although complication rates are rare in most series, there remains a concern regarding exposed temporary K-wire fixation, which has led to the development of multiple permanent internal fixation options.

Abstract
There are several forefoot conditions that can result in metatarsal head pain. Various points of the gait cycle can predispose the metatarsal heads to pain based on intrinsic and extrinsic imbalances. Metatarsalgia can further be classified according to primary, secondary, or iatrogenic etiologies. Within these groups, conservative management is the first line of treatment and can often obviate surgical intervention. Depending on the cause of pain, proper shoewear, orthoses, and inserts coupled with targeted physical therapy can alleviate most symptoms of metatarsalgia and lesser toe deformities.

Abstract
Background Diabetic foot ulcers are frequently related to elevated pressure under a bony prominence. Conservative treatment includes offloading with orthopaedic shoes and custom made orthotics or plaster casts. While casting in plaster is usually effective in achieving primary closure of foot ulcers, recurrence rates are high. Minimally invasive surgical offloading that includes correction of foot deformities has good short and long term results. The surgery alleviates the pressure under the bony prominence, thus enabling prompt ulcer healing, negating the patient's dependence on expensive shoes and orthotics, with a lower chance of recurrence. The purpose of this protocol is to compare offloading surgery (percutaneous flexor tenotomy, mini-invasive floating metatarsal osteotomy or Keller arthroplasty) to non-surgical treatment for patients with diabetic foot ulcers in a semi-crossover designed RCT. Methods One hundred patients with diabetic neuropathy related foot ulcers (tip of toe ulcers, ulcers under metatarsal heads and ulcers under the hallux interphalangeal joint) will be randomized (2:3) to a surgical offloading procedure or best available non-surgical treatment. Group 1 (surgery) will have surgery within 1 week. Group 2 (controls) will be prescribed an offloading cast applied for up to 12 weeks (based on clinical considerations). Following successful offloading treatment (ulcer closure with complete epithelization) patients will be prescribed orthopaedic shoes and custom made orthotics. If offloading by cast for at least 6 weeks fails, or the ulcer recurs, patients will be offered surgical offloading. Follow-up will take place till 2 years following randomization. Outcome criteria will be time to healing of the primary ulcer (complete epithelization), time to healing of surgical wound, recurrence of ulcer, time to recurrence and complications. Discussion The high recurrence rate of foot ulcers and their dire consequences justify attempts to find better solutions than the non-surgical options available at present.

Abstract
UNLABELLED Forefoot and lesser digital pathology continues to be a challenging area of surgical correction for foot and ankle surgeons. Many techniques for the correction of digital deformities secondary to plantar plate rupture, regardless of planal dominance, have been described including direct repair and metatarsal shortening osteotomies for repair. The authors present a new technique for multiplanar correction of deformed lesser digits without direct repair of the plantar plate rupture utilizing a specialty suture. The technique utilizes a braided synthetic polyethylene Nylon suture, which has been traditionally used for open or arthroscopic shoulder labrum repair, for the stabilization of the lesser metatarsophalangeal joint. This novel technique guide for the correction of transverse and sagittal plane deformities of the digit at the metatarsophalangeal joint negates the need for a plantar incisional approach for plantar plate repair or metatarsal head osteotomy from a dorsal approach with augmented stabilization. LEVELS OF EVIDENCE Level V: Expert opinion.

Comparison of the effects of forefoot joint-preserving arthroplasty and resection-replacement arthroplasty on walking plantar pressure distribution and patient-based outcomes in patients with rheumatoid arthritis. PLoS One 2017; 12:e0183805. [PMID: 28850582 PMCID: PMC5574579 DOI: 10.1371/journal.pone.0183805] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2017] [Accepted: 08/13/2017] [Indexed: 11/24/2022] Open
Abstract
Purpose The purpose of this retrospective study is to clarify the difference in plantar pressure distribution during walking and related patient-based outcomes between forefoot joint-preserving arthroplasty and resection-replacement arthroplasty in patients with rheumatoid arthritis (RA). Methods Four groups of patients were recruited. Group1 included 22 feet of 11 healthy controls (age 48.6 years), Group2 included 36 feet of 28 RA patients with deformed non-operated feet (age 64.8 years, Disease activity score assessing 28 joints with CRP [DAS28-CRP] 2.3), Group3 included 27 feet of 20 RA patients with metatarsal head resection-replacement arthroplasty (age 60.7 years, post-operative duration 5.6 years, DAS28-CRP 2.4), and Group4 included 34 feet of 29 RA patients with metatarsophalangeal (MTP) joint-preserving arthroplasty (age 64.6 years, post-operative duration 3.2 years, DAS28-CRP 2.3). Patients were cross-sectionally examined by F-SCAN II to evaluate walking plantar pressure, and the self-administered foot evaluation questionnaire (SAFE-Q). Twenty joint-preserving arthroplasty feet were longitudinally examined at both pre- and post-operation. Results In the 1st MTP joint, Group4 showed higher pressure distribution (13.7%) than Group2 (8.0%) and Group3 (6.7%) (P<0.001). In the 2nd-3rd MTP joint, Group4 showed lower pressure distribution (9.0%) than Group2 (14.5%) (P<0.001) and Group3 (11.5%) (P<0.05). On longitudinal analysis, Group4 showed increased 1st MTP joint pressure (8.5% vs. 14.7%; P<0.001) and decreased 2nd-3rd MTP joint pressure (15.2% vs. 10.7%; P<0.01) distribution. In the SAFE-Q subscale scores, Group4 showed higher scores than Group3 in pain and pain-related scores (84.1 vs. 71.7; P<0.01) and in shoe-related scores (62.5 vs. 43.1; P<0.01). Conclusions Joint-preserving arthroplasty resulted in higher 1st MTP joint and lower 2nd-3rd MTP joint pressures than resection-replacement arthroplasty, which were associated with better patient-based outcomes.
