Current Foot & Ankle Projects

Identifying the optimal position for minimally invasive 1st metatarsal osteotomy for hallux valgus reconstruction: a cadaveric study.
Objective(s):
- Perform a 4th generation MIS transverse osteotomy on cadavers utilizing the surgical guidelines provided from Chin et al4. We will then perform a dissection to assess the location of the osteotomy, and whether it is intra vs. extra articular.
- An x-ray will be done to better understand the anatomic features that correspond to the intra vs. extra articular location. - The vasculature of the distal metatarsal will be observed with ink.
- The results of our study are intending to provide recommendation to surgeons on where to make the osteotomy when it comes to treatment of hallux valgus, and also validate and extend any findings surrounding current literature.

Normative Data for Lateral Talar Subluxation in the Weight-Bearing Ankle.
Objective(s):
- Define the mean LTS value in a population with normal ankle anatomy
- Define the mean LTS value with subanalyses according to biological sex and ankle side
- Compare mean LTS to mean values for existing radiographic measurement tools of MCS and SCS

3D Printing technology as a method for preoperative reconstructive surgical planning, phase 1.
Objective(s):
- While CN reconstruction and DIEP flap surgery are continuously improving, there is a need from both surgeons and patients for research to optimize surgical interventions. 3D printing is a promising tool, and we hypothesize that it will be effective for surgeons during presurgical planning for CN and DIEP flap surgery.
- This study aims to determine if it is feasible to use the artificial intelligence laboratory to produce 3D printed models from functional magnetic resonance imaging (MRI) for both procedures.

Plantar capsule release combined with tenotomy for the release of a rigid hammertoe – cadaveric study
Objective(s):
- Since isolated tenotomies are effective for flexible hammer toes and current procedures for rigid hammer toes pose significant risks to patients, we hypothesize that extending the tenotomy approach into the PIP joint capsule to release the plantar capsule may correct the rigid PIP joint flexion deformity. This technique could substantially improve alignment while avoiding the use of wires or implants, thereby reducing the risk of nonhealing, ulceration and amputation.
- With the aim of identifying a novel technique to restore range of motion in a rigid hammer toe, we will perform a cadaveric study to optimize access to the plantar aspect of the PIP joint capsule and evaluate safety of adjacent neurovascular structures with this approach.

The Clinical Anatomy of the Extensor Retinaculum of the Ankle
Objective(s):
- This research aims to provide morphofunctional considerations with gross anatomical and histological studies of the superior and inferior retinacula.
- Through morphometric analysis, we will identify the best tissue for repair during TAAs, ultimately improving surgical outcomes and reducing postoperative complications.

Articular Cartilage and CFL Ligament Damage Following Fibular Nail Insertion: A Cadaveric Study
Objective(s):
- Damage to the cartilage or ligaments in the ankle can lead to degenerative changes and arthritis over time, potentially causing long-lasting disability. It is crucial to minimize harm to cartilage and ligaments because they play a vital role in joint function and overall joint health long term.
- Our study aims to address this gap by performing 10 IM nail fixations on cadaveric lower limbs and measuring the distance from and damage inflicted on structures of interest to evaluate the safety and effectiveness of fibular insertion surgery compared to traditional methods.
