Lapidus Arthrodesis for Correction of Hallux Valgus Deformity: A Systematic Review and Meta-Analysis.

Foot and Ankle International

The aim of this study was to evaluate and compare different fixation methods to achieve Tarsometatarsal joint I (TMT-1) arthrodesis in patients with hallux valgus regarding radiographic correction, complication profile, and clinical outcomes.

A systematic review and meta-analysis included primary literature results of evidence level 1 to 3 studies in German and English. Inclusion and exclusion criteria were established and applied, along with parameters suitable for comparison of data.

16 studies with a total of 1176 participants met the inclusion criteria for this analysis. Twelve evaluation criteria were compared among 3 fixation techniques; comprised of a screw-only, dorsomedial plating- and plantar plating cohort. There was no statistical difference in deformity correction (both intermetatarsal- and hallux valgus angle), or AOFAS score between the cohorts. The complication rate was 13% in the plantar-, 19.5% in the dorsomedial-, and 24.5% in the screw cohort. Nonunion was seen in 0.7% of participants in the plantar, 1.4% in the dorsomedial, and 5.3% in the screw group. The time until complete weightbearing correlated positively with the development of nonunion, with a coefficient of 0.376 (P = .009). Hardware removal was performed in 11.8% of patients in the dorsomedial cohort, 7.7% in the screw cohort, and 3.6% in the plantar cohort.

Based on the results of meta-analysis of heterogeneous studies, plantar plating facilitated early weightbearing and patient mobilization compared to the other fixation methods, while carrying the lowest nonunion, hardware removal, and general complication risk. However, owing to the relatively small number of patients in the plantar plating group, more work is necessary to elucidate the benefits of plantar plating for a first tarsometatarsal joint arthrodesis. Development of complications appears to be largely dependent on the fixation model, rather than patient mobilization alone.Level of Evidence: 3.

Correlation between Clinical Outcome and Radiologic Features After Open Reduction and Internal Fixation of Calcaneal Fractures.

Am Podiatry Assoc

We aimed to find probable correlation between postoperative radiologic variables and clinical outcomes of surgically treated calcaneal fractures.

In a retrospective study, 70 unilateral displaced intraarticular calcaneal fractures in adults with follow-up more than 1 year were asked to have a visit. Weightbearing radiographs of both ankles were taken and radiologic parameters, including the differences in values in Böhler and Gissane angles in comparison with the uninjured side, and calcaneocuboid and subtalar joint arthritis based on the Kellgren-Lawrence grading scale, were evaluated. They were considered to find any correlation with clinical outcomes assessed by American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale, visual analogue scale, Foot Function Index, and Tegner Activity Scale.

A total of 61 men (87.1%) and nine women (12.9%) with a mean age of 38.9 ± 12.7 years (range, 18-67 years) were included. Mean follow-up visit for the patients was 25.1 ± 12.7 months. Mean scores of American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale, visual analogue scale, Foot Function Index, and Tegner Activity Scale were 86.7 ± 12.9, 21.3 ± 22.2, 13.1 ± 15.4, and 5.2 ± 1.1, respectively. The mean Gissane angle and Böhler angle differences were -0.2 ± 8.6 and -3.7 ± 7.2, respectively. Regarding the calcaneocuboid arthritis, 50 (71.4%), 14 (20.0%), and six patients (8.6%) were categorized in grades 0, 1, and 2, respectively. Also, subtalar arthritis was seen in 15 (21.4%), 24 (34.3%), 20 (28.6%), and 11 patients (15.7%), categorized as grades 0, 1, 2, and 3, respectively. No statistical correlation was found between any of the radiologic variables and clinical scores.

There was no significant correlation between Böhler and Gissane angles and the clinical outcomes in surgically treated calcaneal fractures. Also, functional outcomes do not change considerably among different grades of arthritis in calcaneocuboid and subtalar joints, at least during short- to mid-term follow-up periods. Radiologic findings after open reduction and internal fixation of calcaneal fractures are not predictors of function of the patients.

Achilles Tendon Stiffness in the Etiology of Sever Disease: A Shear Wave Elastography Study.

Am Podiatry Assoc

Sever disease is one of the most common causes of heel pain in growing children and adolescents. There is no consensus about etiology of Sever disease.

The study comprised 41 participants aged 8 to 13 years who visited the orthopedic outpatient clinic: 17 patients with Sever disease and 24 asymptomatic children. The middle third segment of the body of the Achilles tendon and the calcaneal insertion zone were separately assessed. Five measuring points for the quantitative value of each point were randomly selected. The color scale used in the Young's modulus shows the lowest values in blue and the highest values in red. The mean values were used for the statistical analysis.

Less elasticity was detected at the insertional site for the control group (4.02 kPa versus 3.65 kPa), the situation was reversed in the body of the Achilles tendon and the elasticity of the study group was less than that of the control group (241.0 kPa versus 260.5 kPa). However, no statistically significant difference was found between the groups.

In conclusion, no difference was found in Achilles tendon elasticity between patients with Sever disease and healthy individuals in both the tendon body and the calcaneal insertionof the tendon. Achilles tendon elasticity has not been found to play a role in the etiology of Sever disease.

Assessment of Ingrown Toenails Treated with Nail Fold Cryotherapy in Adolescent Patients: An Observational Pilot Study.

Am Podiatry Assoc

Cryotherapy reduces pain by making some reversible functional changes in peripheral nerves. It has also been reported to have a positive effect on the regression of inflammation and granulation tissue. Few studies have evaluated the efficacy and safety of nail fold cryotherapy in ingrown toenails (IGTN) in adults, and there are no studies in the pediatric population. We aimed to evaluate the clinical efficacy of cryotherapy applied to the nail fold in juvenile IGTN.

This study was conducted in adolescent patients aged 12 to 16 years with unilateral juvenile IGTN. Liquid nitrogen was sprayed into the nail fold for 10 to 15 seconds with a double freeze-thaw cycle. The effectiveness of cryotherapy was interpreted by the clinician's decision, the improvement in visual analogue scale score, Children's Dermatology Life Quality Index score, and granulation tissue.

According to the physician, good efficacy was achieved in 91.7% of patients (n = 22 of 24). We found that 54.5% of them (n = 12 of 22) were still in remission after 6 months. Rates of complete regression in granulation tissue were pronouncedly less in sizes larger than 5 mm (≤5 mm, 55.6%; >5 mm, 16.7%). However, adequate symptomatic relief was observed in 83.3% of stage 3 patients, even if complete granulation tissue response was not achieved yet. Significant improvements in visual analogue scale and the Children's Dermatology Life Quality Index scores were observed after cryotherapy (P < .05).

Nail fold cryotherapy is a useful alternative among conservative methods because of its rapid and high efficiency (91.7%), especially in mild to moderate cases, despite the high recurrence rates (45.5%) in juvenile IGTN.

Association of Demographic Characteristics and Laboratory Values in Diabetic Foot Infections Leading to Lower-Extremity Amputation.

Am Podiatry Assoc

Lower-extremity amputations are a common complication of poorly controlled diabetes and contribute to significant morbidity and mortality in diabetic patients. We sought to determine whether objective data points obtained on presentation or hospital admission, including white blood cell (WBC) count, hemoglobin A1c (HbA1c), C-reactive protein (CRP), and descriptive patient demographics allow for the ability to predict optimal amputation levels and outcomes of lower-extremity amputation in the diabetic population.

A retrospective analysis of 162 patients was performed evaluating laboratory and descriptive values on hospital presentation for lower-extremity infection during a 16-year period. Occurrence of multiple amputations and level of amputation were assessed against laboratory values to determine whether these objective values would provide clinicians with a better understanding of amputations in the diabetic patient.

The mean patient age was 60.6 years. A significantly higher percentage of patients who underwent amputations through the tibia and fibula or of the foot midtarsal were male compared with patients who underwent amputations of the thigh through femur. Patients who had amputations through the tibia and fibula had a significantly higher WBC count compared with patients who had a transmetatarsal amputation (P = .03). There was no significant difference in type or quantity of amputations when analyzing HbA1c and CRP levels.

An admission WBC count may be used as a predictor of lower-extremity amputation level and outcomes in diabetic infections. Although a statistically significant difference was not found for CRP or HbA1c levels between amputation procedures and number of procedures performed, these values remain useful in managing lower-extremity infections in diabetic patients.

Primary Arthrodesis versus Open Reduction and Internal Fixation for Lisfranc Joint Fracture-Dislocations in Adults: A Systematic Review.

Am Podiatry Assoc

The Lisfranc joint is an intricate podiatric medical structure that when injured can prove difficult to treat. No consensus has been established on optimal surgical management for this injury. It is widely debated whether open reduction and internal fixation or primary arthrodesis provides better outcomes for patients. Although literature has been published on this subject, no generalized guidelines have been created. The goal of this study was to analyze high-level meta-analyses to draw conclusions about surgical interventions for Lisfranc joint injuries.

A literature review was conducted to analyze outcomes of meta-analyses from January 1, 2016, to August 31, 2021. Only high-level evidence that reported at least one of the following outcomes was included: American Orthopaedic Foot and Ankle Society scale score, visual analog scale score, total complication rate, hardware removal rate, revision surgery rate, and secondary procedure rate.

Six articles met the inclusion and exclusion criteria and were then analyzed. For all of the outcome measures, primary arthrodesis was equal or superior to open reduction and internal fixation.

We recommend primary arthrodesis over open reduction and internal fixation for adult Lisfranc injuries.

Winograd Wedge Resection Matrixectomy versus Partial Nail Avulsion with Chemical Cautery: A Tertiary Institution's Clinical Outcomes and Proposed Triaging Protocol.

Am Podiatry Assoc

Onychocryptosis, or ingrown toenail, is a common condition affecting patients of varying age groups, although usually, younger patients are affected.

We compared two techniques used in our institution: Winograd wedge resection with matrixectomy (WG-M) versus partial nail avulsion with phenolization of the nail matrix (PNA-P).

Primary outcomes of interest were presence of nail regrowth and patient satisfaction postoperatively. Secondary outcomes were postoperative pain (within the first 2 weeks and after 2 weeks), postoperative inflammation, and healing time. A total of 65 patients were included in this study: 44 patients (19 female and 25 male patients), with a mean age of 45.7 years (range, 16-83 years) underwent WG-M in the orthopedic surgery department, whereas a total of 21 patients (10 female and 11 male patients), with a mean age of 44.5 years (range, 13 to 75 years) underwent PNA-P in the podiatry department. In patients who underwent WG-M, there was one case of regrowth (2.3%) compared with no regrowth cases (0%) in the PNA-P group. There was no significant difference in regrowth rate between the two procedures (P = .494). The satisfaction rate was high for both procedures: 100% patients in the WG-M group rated themselves better than before surgery, compared with 95.7% in the PNA-P group.

From our study, we conclude that both techniques (WG-M and PNA-P) are able to achieve similar clinical outcomes, with the PNA-P procedure being less invasive and less resource intensive, and also achieving a shorter healing time.

The Effect of the Lateral First Metatarsal Head Shape on Hallux Valgus in Forced Turnout in Pre-Pointe Female Ballet Dancers: A Pilot Study.

Am Podiatry Assoc

A rounded lateral first metatarsal head shape is associated with higher rates of hallux abducto valgus recurrence following corrective surgery; however, the effect of the lateral first metatarsal head shape on the hallux abduction angle (HAA) has not yet been explored in a nonpathologic, pre-pointe ballet dancer population. The primary purpose of this study was to investigate the effect of the lateral first metatarsal head shape on the HAA when pre-pointe female dancers force their turnout.

Seventeen female, pre-pointe ballet students (mean age, 10.8 ± 0.95 years) participated in this study. Fluoroscopic images of each dancer's dominant foot were taken, and the lateral first metatarsal head shape was classified visually. Each dancer performed three consecutive stances of natural double-leg upright posture: both functional and forced turnout. HAAs were obtained by marking medial bony landmarks on paper and were compared to photographic measurements.

No significant difference was found between the round and angular lateral first metatarsal head shape for the change in HAA from natural double-leg upright posture to forced turnout. Hallux abduction angle significantly increased by 4.6° (P < .001) in forced turnout compared to the natural double-leg upright posture for the photographic method, whereas the paper method demonstrated an increase of 2.6° (P = .007). No statistical differences were found between the paper and photographic methods in measuring the HAA for all stances.

Our findings suggest no association between the HAA and lateral first metatarsal head shape; however, HAA does increase when a dancer assumes forced turnout. The paper method demonstrated similar reliability to the photographic method and shows the potential for future use as a clinical tool in assessing hallux abducto valgus.

Association Between Altmetrics and Traditional Bibliometrics in the Journal of the American Podiatric Medical Association and The Journal of Foot and Ankle Surgery.

Am Podiatry Assoc

As the dissemination of scientific knowledge pervades social media, appraising impact with traditional bibliometrics led to the creation of alternative metrics, termed altmetrics. Lacking existent foot and ankle surgery literature altmetric analysis, we analyzed the 10 most-cited articles in the Journal of the American Podiatric Medical Association (JAPMA) and The Journal of Foot and Ankle Surgery (JFAS) in 2013 and 2017.

Citation count, Altmetric Attention Score (AAS), Mendeley Reads, and professional society-affiliated Twitter ages were collected and analyzed with descriptive statistics. Pearson correlation coefficient identified relationships between traditional and nontraditional metrics.

The 40 articles showed a high median and large range in total citations for JAPMA (13.5 [range, 5-27]) and JFAS (28 [range, 5-69]). Media AAS Mendeley Reads also showed a high median with wide range for both JAPMA (32.5 [range, 0-135]) and JFAS (25 [range, 0-113)]. No significant correlation between total citations and AAS was seen in 2013 (r = -0.205; P = .388) or 2017 (r = -0.029; P = .903). The correlation between total citation count and Mendeley reads was significant in 2017 (r = 0.646; P = .002) but not in 2013 (r = -0.078; P = .744). Although cumulative AAS increased from 2013 to 2017 by 68.75%, with Twitter contributing most to both periods, there existed no significant correlation with Twitter age and the correlation coefficient between AAS and total citations (r = 0.655; P = .173).

The results of this investigation show the utility and predictivity of alternative metrics in complementing traditional bibliometrics and encourage the promotion of publications through journal-specific social media.

Retrospective Analysis of Radiographic Outcomes After Closing Base Wedge Osteotomy for Correction of Bunion Deformity.

Am Podiatry Assoc

Closing base wedge osteotomy (CBWO) is a common procedure to correct severe bunion deformities with high intermetatarsal angles. There are few data demonstrating the radiographic success of CBWOs.

We evaluated the radiographic outcomes of a CBWO. The primary aim was to assess the change in elevatus after a CBWO. Secondary aims included measuring the change in hallux abductus (HA) and intermetatarsal angles after the osteotomy. The medical records of 24 consecutive patients across 4 years were reviewed. All of the CBWOs were fixated with either one screw and one Kirschner wire or two screws. We hypothesized that the CBWO would reduce the amount of elevatus present.

The mean patient age was 35 years. Average preoperative HA and intermetatarsal angles were 35.2° and 15.7°, respectively. Mean postoperative HA and intermetatarsal angles at last radiographic follow-up were 13.3° and 6.1°, respectively. The change in HA and intermetatarsal angles was 21.9° and 9.6°, respectively. All of the patients achieved clinical union. Mean radiographic follow-up was 6 months; median radiographic follow-up was 5 months. The mean preoperative elevatus measurement was 3.5 mm; the mean postoperative elevatus measurement was 2.0 mm (difference, -1.6 mm; P = .0282), indicating that the osteotomy plantarflexed the first metatarsal. Three patients had radiographic evidence of postoperative elevatus; they were asymptomatic at the last clinical follow-up.

Although clinical concern persists for the development of postoperative elevatus with CBWO, this case series showed plantarflexion of the CBWO. The CBWO is a powerful yet stable procedure for severe bunion deformities and should be viewed as a viable alternative to the Lapidus procedure.
