Background: Total ankle replacements (TARs) have rapidly advanced in terms of volume, technique, design, and indications. However, TARs are still at risk for early mechanical failure revision. Prior studies investigated potential factors failure, but been limited to smaller series or older implants. This study sought identify modern TAR. Methods: is a retrospective single-institution registry. Five surgeons contributed cases involving patients who underwent primary TAR with any implant....

Background: Medial gutter impingement may compromise the results of an otherwise well-fixed total ankle arthroplasty (TAA), but no previous study has assessed predisposing factors. This case-control sought to investigate potential risk factors and role talar component downsizing in decreasing medial impingement. Methods: A retrospective with 149 patients was performed. Thirty-four reoperated for were identified matched a control group 115 patients. Radiographic parameters included pre-...

It showed substantial inter- in describing it; however, evaluation has not been performed.Anteroposterior lateral radiographs, computed tomography scans, magnetic resonance imaging 65 patients with acute traumatic injuries were selected classified using morphologic grading by 6...

Ankle arthritis leads to an elevated joint line compared the nonarthritic ankle, as measured by "joint height ratio" (JLHR). Previous work has shown that JLHR may remain after total ankle arthroplasty (TAA). However, clinical impact of this yet be determined. This study assessed correlation between postoperative JLHR, post-TAA range motion (ROM), and 1-year Patient-Reported Outcome Measurement Information System (PROMIS) scores.

Establishing a surgical plan for ankle deformities necessitates comprehensive understanding of the deforming forces involved, and morphology deformity plays an important role as well. Valgus tibiotalar tilt development has mostly been described in patients with low medial longitudinal arch, seen progressive collapsing foot (PCFD). However, some valgus ankles demonstrate no radiographic evidence collapsed arch. This study aims to investigate whether there are differences between without arch...

Background: Although intraoperative ankle motion serves as a foundational reference for anticipated after surgery and guides the addition of procedures to enhance in total arthroplasty (TAA), relationship between postoperative remains unclear. This study aimed investigate discrepancy range (ROM) following TAAs using anterior-approach, fixed-bearing systems. Methods: retrospectively reviewed 67 patients (67 ankles) who underwent primary TAA at single institution. Three different types systems...

Minimally invasive bunionectomy (MISB) has emerged as a popular approach to treat symptomatic hallux valgus deformity. Although previous studies focused on distal foot width changes postsurgery, this research introduces novel midshaft measurement evaluate proximal transverse midfoot width, aiming for comprehensive understanding of post-MISB.

There are limited data regarding risk factors associated with periprosthetic medial malleolar fractures in total ankle arthroplasty (TAA). This case-control study aimed to identify the and analyze effect of prophylactic screw fixation preventing a fracture after TAA.

A new pilon fracture classification system based on CT scan data was recently published, showing almost perfect interobserver and intraobserver agreement among the authors who developed it. However, an independent assessment has not been done.To do evaluation of with physicians different levels expertise in management fractures.Seventy-one cases acute were retrospectively collected. Fractures classified by six evaluators (three foot ankle surgeons three orthopaedic surgery residents) using...

Isolated subtalar and talonavicular joint arthrodeses have been associated with adjacent arthritis altered hindfoot kinematics during simplified loading scenarios. However, the effect on dynamic activity is unknown. This study assessed changes in after isolated (TN

Background: Although an association between intercuneiform (C1-C2) joint instability and the recurrence of hallux valgus (HV) deformity after modified Lapidus procedure has been suggested, there is currently no radiographic evidence to support it. This study aims investigate changes in C1-C2 for HV correction, using weightbearing computed tomography (WBCT). Methods: retrospective cohort included 52 feet (50 patients) with who underwent had preoperative postoperative WBCT. Patients additional...

Posterior malleolus fractures occur in up to 50% of all ankle fractures. Several classification systems exist for their characterization, especially under CT. However, those classifications do not report the level agreement or it incompletely. This study aims independently assess three posterior fracture (Haraguchi, Bartoníček/Rammelt, and Mason).This was designed according Guidelines Reporting Reliability Agreement Studies. Ninety-four CT scans patients with that had were included. assessed...

A new method for measuring the principal residual stresses on surface of a thin metallic specimen is presented. The novelty resides in combination layer removal technique by chemical etching and electronic speckle pattern interferometry to measure ensuing deformation. It shown that loci constant deflection with respect original plane are conic sections. An interferometer sensitive out-of-plane displacements was used, yielding fringe patterns reproduced those curves. Immediate visualization...

Introduction/Purpose: Polyethylene wear is a concern for failure of any joint replacement, including total ankle arthroplasty (TAA). Heterogeneity in bearing surface design among current TAA systems show no clear solution to the competing objectives function (constraint and kinematics) (contact stresses). Literature has begun investigate polyethylene damage; however, comprehensive understanding patterns vivo location remains unknown. This study aims quantify type severity differing damage...

Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Following Minimally Invasive Bunionectomy (MISB), removal of hardware rates are about 5% and commonly due to midfoot pain near the distal metatarsal screw site. This head site corresponds proximal midshaft width measurement location, which has shown increase postoperatively. One explanation for this increased is medial subluxation first at tarsal-metatarsal (TMT) joint. “TMT slippage” occurs as base shifted medially accommodate...

Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Hallux Valgus (HV) is a common foot condition often requiring surgical intervention. Minimally invasive bunionectomy (MISB) has gained popularity for HV correction. While previous research focused on distal width changes following surgery, this study introduces novel midshaft measurement to assess proximal transverse midfoot width. The aims provide comprehensive evaluation of post-MISB. Methods: A retrospective review prospectively...

Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Hallux valgus(HV) is a triplanar deformity that includes the pronation of first ray. Although there little data regarding effect on clinical outcomes, rotational component HV may play an important role. One study suggested modified Lapidus technique effectively decreased However, no evidence for alternative procedures such as minimally invasive(MIS) bunionectomy. This sought to assess if MIS bunionectomy can correct ray's and determine...

Category: Sports; Other Introduction/Purpose: Minimally invasive approaches to Achilles tendon (AT) repair have garnered significant attention due their reported effectiveness. Due the limited visibility of tendon, a crucial factor for success these lies in precise targeting and adequate capture substance. Insufficient can lead re-rupture or elongation, potentially leading poor patient-outcomes. Since many current techniques devices minimally AT rely on needle passage through single axial...

Category: Hindfoot; Basic Sciences/Biologics Introduction/Purpose: Talonavicular and subtalar joint arthrodeses are frequently performed in isolation. While these procedures generally produce good results, patients often experience reduced range of motion (ROM) adjacent hindfoot arthritis. Several studies have shown that the arthrodesis a single considerably limits unfused joints during simplified loading scenarios, but effect on kinematics dynamic activity is unknown. This study sought to...
