Treatment outcomes for Achilles tendon ruptures depend upon prompt diagnosis and management. A local study in 2018 highlighted inefficiencies in patient management, and a revised protocol was introduced allowing investigation and referral to be initiated by other healthcare professionals. This retrospective audit evaluates the impact of this on the timescale from presentation to treatment. It analyzes all suspected Achilles tendon ruptures within one District General Hospital from April 2021 to March 2022. Data regarding patient timelines was compared to the 2018 study. Over 12 months, 99 patients were referred to Virtual Fracture Clinic, 87.8% (n = 87) of which had a complete or partial tear on ultrasound scan (USS). In comparison to 2018, the average time from presentation to USS request reduced from 2.9 to 1.1 days (p < .01). 95% were scanned within one week of USS request and 31.3% within 48 hours (81% and 18%, previously). The average time from USS request to scan went from 6.8 to 3.2 days (p < .01). The time from presentation to treatment decision reduced from 10.9 to 6.2 days (p < .01) and the percentage of patients with a definitive treatment plan within one week increased from 34.5% to 74.2% (p < .01). Patients required 0.8 fewer appointments (p < .01) giving an estimated total saving of $10,110 ($128 per patient) during the analyzed period. The Achilles Tendon Rupture Pathway has significantly improved the proportion of patients undergoing USS within 48 hours and receiving a treatment decision within one week. This study demonstrates an efficient, cost-saving and replicable pathway for Achilles tendon ruptures.

The medial plantar artery flap (MPAF) presents both unique value as well as significant challenges. As the plantar foot has specific anatomy, the use of the MPAF to recreate this highly specialized area may provide improvements in durability and rates of limb salvage. The purpose of this study is to establish the anatomic course of the branching patterns of the medial plantar artery (MPA) and provide a foundation for MPA flap nomenclature as it is related to design and elevation. Thirty-seven fresh frozen cadaver feet were used for dissection: 20 right and 17 left sided limbs. Anatomic measurements recorded included: branching pattern of the MPA, bifurcation distance of the superficial branch (SB) and deep branch (DB) from the origin of the MPA, distance from the MPA origin to the anterior colliculus of the medial malleolus, and the distance from the SB and the DB to the navicular tuberosity. The MPA was found to bifurcate into SB and DB in 30 (81%) specimens; 6 (16%) specimens had only a SB, whereas 1 (3%) specimen had only a DB, which had not been previously described. The distance from the anterior colliculus to the MPA was 3.0 cm, MPA to the distal bifurcation was 2.9 cm, and navicular tuberosity to the SB and DB was 2.2 cm and 1.3 cm, respectively. Minimizing the complexity of the dissection with the use of more reliable landmarks and a deeper understanding of the anatomy may reduce complications and allow for more reproducible outcomes when utilizing the MPAF.

Tarso-metatarsal joints and naviculocuneiform joints comprising midfoot is the second most commonly involved joints following the first metatarsophalangeal joint in the foot. However, related factors of midfoot arthritis (MA) have been rarely reported. The bony structure and alignment can be more precisely assessed using Weight-Bearing Computed Tomography (WBCT) than conventional radiographs. Therefore, the aim of this study was to investigate risk factors for MA related to medical history and comorbid foot deformities using WBCT. WBCT data from September 2014 to April 2022 were extracted from a single referral hospital. All cases were divided into two groups by the presence of MA. Twenty-five potential related factors including demographics, etiology, and common co-occurring foot deformities were collected for comparison. Six hundred six cases (247 males and 359 females) among consecutive 1316 cases between September 2014 to April 2022 were selected. One hundred thirty-nine male cases (56.3%) and 210 female cases (58.5%) showed MA. In stepwise multiple logistic regression analysis, 5 factors remained statistically significant. The multivariate-adjusted odds ratios for age, laterality, body mass index (BMI), Progressive Collapsing Foot Deformity (PCFD), and lesser toe deformities (LTD) were 1.08, 1.54, 1.05, 6.62, and 3.03 respectively. Risk factors for MA associated with medical history and foot deformities included age, laterality, BMI, PCFD, and LDT.

Surgical site infections (SSIs) are a notable complication following open reduction and internal fixation (ORIF) for ankle fractures. The purpose of this study was to (1) compare baseline demographics of patients who did and did not develop SSIs within 90 days following ORIF for trimalleolar ankle fractures and (2) identify risk factors associated with SSIs in this setting. A retrospective analysis from 2010 to 2020 was completed using a national administrative database. The study group consisted of patients who underwent ORIF for trimalleolar ankle fractures and developed SSIs within 90 days postoperatively. Patients without SSIs served as the comparison cohort. Baseline demographics of the two cohorts were compared utilizing Pearson's Chi-Square Analyses. A multivariate binomial logistic regression model determined the association of various comorbidities on developing SSIs in this setting. Out of a total sample of 22,118 patients, 1000 individuals (4.52%) developed SSIs. The study revealed that the SSI cohort exhibited a greater burden of comorbidities, as evidenced by significant differences in various individual comorbidities and average Elixhauser-Comorbidity Indices scores. The most strongly associated risk factors for the development of SSIs following ORIF for trimalleolar ankle fractures were peripheral vascular disease (OR: 1.53, p < .0001), diabetes mellitus (OR: 1.26, p = .0010), iron deficiency anemia (OR: 1.24, p = .0010), male sex (OR: 1.22, p = .0010), and tobacco use (OR: 1.15, p = .0010). This study identified several patient risk factors that were associated with developing SSIs after ORIF for trimalleolar ankle fractures, recognizing potential patient-directed interventions that may reduce the rate of SSIs in this setting.

The present study was to determine the characteristics of the ankle skeletal structure in patients with talus Hepple V type. We conducted a retrospective study on the skeletal structure of the talus in 110 patients with Hepple V osteochondral lesions of the talus and in control participants. The radiographic measurements taken include the following: in the coronal plane - depth of talus frontal curvature, length of the lateral and medial malleolus; in the sagittal plane - radius and height of talus, angle of tibial lateral surface, tibiotalar sector, and vertical neck angle. The osteochondral lesion of the talus showed a significantly larger mean radius (mean ± SD, 21.4 ± 2.5 mm; p < .001) and height (mean ± SD, 26.0 ± 2.7 mm; p < .005). It also demonstrated a longer mean medial malleolus length (mean ± SD, 15.7 ± 2.4 mm; p < .005), a larger mean vertical neck angle (mean ± SD, 86.2 ± 5.4°; p < .050), and a greater mean tibial lateral surface angle (mean ± SD, 80.0 ± 4.5°; p < .001). And there was a greater mean frontal curvature depth (mean ± SD, 3.9 ± 0.6 mm; p < .005). Overall, this study found that patients with Hepple V osteochondral lesions of the talus had a larger vertical neck angle and tibial lateral surface angle, a longer talus radius and medial malleolus length, a higher talus height, and a deeper frontal curvature depth.
