Cross-Sectional Analysis of the Distal Fibular Intramedullary Canal: A Cadaveric Evaluation.

Unlabelled: Fractures of the distal fibula secondary to rotational ankle injuries are one of the most common injuries requiring surgical intervention. The aim of this study was to describe the anatomy of the distal fibular medullary canal as a means of aiding in surgical management with an intramedullary device. Twenty fresh cadaveric below-knee specimens (group 1, 10 in 2015, group 2, 10 in 2016) were dissected to expose the distal fibular.

First Metatarsal Head Osteochondral Defect Treatment With Particulated Juvenile Cartilage Allograft Transplantation: A Case Series.

Background: Focal damage to articular cartilage, also called an osteochondral defect (OCD), can be a cause of pain and decreased range of motion. Recent advancements have led to transplantation techniques using particulated juvenile articular cartilage allograft. This technique has been applied to the first metatarsal head to a very limited degree, with no published results to our knowledge.

Accuracy and Reproducibility Using Patient-Specific Instrumentation in Total Ankle Arthroplasty.

Background: Implant survivorship is dependent on accuracy of implantation and successful soft tissue balancing. System instrumentation for total ankle arthroplasty implantation has a key influence on surgeon accuracy and reproducibility. The purpose of this study was to determine the accuracy and reproducibility of implant position with patient-specific guides for total ankle arthroplasty across multiple surgeons at multiple facilities.

Radiographic Assessment of a Medullary Total Ankle Prosthesis: A Test of Agreement and Reliability.

Unlabelled: Total ankle replacement (TAR) is a viable alternative to ankle fusion in certain patients with end-stage ankle arthritis. Despite the importance of understanding alignment and movement of the prosthesis, there is no standardized radiographic method for evaluating the position and movement of the INBONE 2 prosthesis. The aims of this study were to describe a radiographic measurement protocol for INBONE 2 for clinical practice and research while determining the interobserver and intraobserver reliability using standard weightbearing radiographs.

Assessment of Bone Marrow Aspiration Site Pain in Foot and Ankle Surgery.

Unlabelled: Bone marrow aspiration (BMA) is a validated technique to harvest progenitor cells. BMA has many uses in foot and ankle surgery; however, donor site morbidity is a concern. The purpose of this study was to compare the Visual Analog Scale (VAS) pain scores after BMA at 3 different sites (iliac crest, distal tibia, and calcaneus) over a 12-week postoperative recovery period.

Preliminary Results of Primary Gastrocnemius-Soleus Recession for Midfoot Charcot Arthropathy.

Unlabelled: Background Treatment of Charcot arthopathy of the foot can be challenging. The goal of this investigation was to determine whether primary gastrocnemius-soleus recession could decrease rate of new ulcers, progression of deformity, and amputation in patients with Charcot arthropathy of the midfoot.Methods A retrospective chart review revealed 28 feet in 24 diabetic patients with radiographic evidence of Charcot arthropathy of the midfoot.

Effect of Dorsal Plate Positioning on Dorsiflexion Angle in Arthrodesis of the First Metatarsophalangeal Joint: A Cadaveric Study.

Background: The relationship between dorsal plate positioning and final dorsiflexion angle after first metatarsophalangeal (MTP) joint fusion has not been well established. The main purpose of this study was to investigate whether changes in dorsal plate positioning along the longitudinal axis affect fusion dorsiflexion angle, as excessive dorsiflexion angles can lead to poor clinical results.

Methods: Ten cadaver foot specimens were randomly assigned to 2 groups for first MTP joint fusion: 1 group used a straight plate, and the other group used a 10-degree precontoured plate.

Laser targeting with C-arm fluoroscopy: effect on image acquisition and radiation exposure.

Objectives: Reducing unnecessary radiation exposure from medical imaging is paramount. This study assessed whether a laser aiming guide for C-arm fluoroscopy reduced the number of exposures needed to obtain an acceptable image, thereby reducing total fluoroscopy time for hip, knee, and ankle fluoroscopy.

Methods: An obese cadaver was placed supine on a radiolucent surgical table.
