Synthetic Cartilage Implantation (SCI; Cartiva) is a treatment of hallux rigidus associated with mixed clinical outcomes in the United States. Patients persistent pain typically undergo diagnostic imaging for evaluation. We aimed to characterize radiologic findings SCI and surrounding tissues.This retrospective review patients treated using who underwent magnetic resonance (MRI) pain. Metatarsophalangeal (MTP) joint spaces were compared on plain radiographs foot immediately postoperatively...
Background: The aim of this study was to determine the outcome delayed presentation (at least 6 weeks from time injury) low-energy Lisfranc injuries limited first and second tarsometatarsal joints treated with open reduction internal fixation. Methods: 8 patients an average age at surgery 39.8 years were retrospectively reviewed a mean injury 15.1 (range 6.3 31.1) weeks. We used radiographic measurements, physical examination, SF-12 scores, Foot Ankle Ability Measure (FAAM) VAS scores return...
Category: Midfoot/Forefoot Introduction/Purpose: The aim of this study was to determine the outcomes and early complications following implantation a novel hydrogel synthetic cartilage implant (SCI) for treatment hallux rigidus by single surgeon. This FDA approved in United States July 2016. Methods: A retrospective chart review consecutive patients who underwent with an SCI between August 2016 June 2018 surgeon performed. Demographic information, radiographic assessment, concomitant...
Hallux valgus is the most common disorder of hallux and often results in pain, functional disability, impaired gait patterns. The goals surgical management are to correct deformity while improving patients’ pain function. Traditional treatment moderate severe deformities consist proximal osteotomy and/or arthrodesis given their powerful corrective ability. Despite power, osteotomies more technically demanding, have a higher rate complications, require restricted post-operative recovery. We...
Background. The aim of this study was to determine the accuracy ankle arthroscopy as a means for diagnosing syndesmotic reduction or malreduction and anatomical landmarks diagnosis. Methods. Six matched-pair cadavers (n = 12) with through-knee amputations were studied. Component parts syndesmosis distal 10 cm interosseous membrane (IOM) sectioned in each. 12 specimens divided into 2 groups: 6 in-situ group fixed suture button technique malreduced rigidly held 3.5-mm screw. Specimens...
Category: Ankle Arthritis; Introduction/Purpose: The INVISION Total Arthroplasty System (Wright Medical Technology/Stryker) is a modular ankle arthroplasty used for patients with limited bone stock. There early survivorship and clinical outcomes data this device. aim of study to report on implant complications specifically regards the talar component performed in complex revision total replacements. Methods: This single-institution retrospective review who underwent TAA using talus between...
Background: The aim of this study was to determine the early outcomes and complications following implantation a hydrogel synthetic cartilage implant (SCI, Cartiva) for treatment hallux rigidus by single surgeon. Methods: A retrospective chart review performed consecutive patients who underwent with an SCI between August 2016 April 2018 Demographic information, radiographic assessment, concomitant operative procedures were evaluated all patients. Postoperatively, PROMIS physical function...
Category: Midfoot/Forefoot, Trauma Introduction/Purpose: The objective of this study was to compare the stability fixation ligamentous Lisfranc injuries stabilized using two devices: a novel plate and conventional transarticular screws. Methods: A biomechanical cadaver model developed that traditional fixation, Thirteen pairs cadaveric specimens were tested intact, after simulated injury, implant fixation. Optical motion tracking used measure three dimensional (3D) between each following...
Category: Hindfoot; Ankle; Diabetes Introduction/Purpose: Achieving adequate fixation is a critical component for successful fusion. Internal can be compromised in the setting of poor bone quality due to open trauma, infection, osteoporosis, neuropathic arthropathy resulting published ankle non-union rates 38% high risk patients. These failures may magnified by weightbearing non-compliance. While use multiplanar external (MEF) alone utilized - it often require an extended period time within...
