Weight-bearing X-Ray Needed for Diagnosis of Subtle Lisfranc Injury
Christopher W. DiGiovanni, MD, and colleagues from the Foot and Ankle Research and Innovation Lab at Mass General found that, for patients with surgically confirmed Lisfranc instability, weight-bearing (WB) radiographs revealed significantly larger diastasis in the tarsometatarsal joint than non-WB radiographs.

Weight-bearing CT Detects Subtle Syndesmotic Instability in Presence of Fibular Fracture
Rohan Bhimani, MD, MBA, Daniel Guss, MD, MBA, and colleagues in the Foot and Ankle Research and Innovation Laboratory at Massachusetts General Hospital found that, even in the presence of a Weber B lateral malleolar ankle fracture, weight-bearing CT is still able to distinguish a stable from an unstable syndesmosis.

Sagittal Plane Fibular Motion More Accurate Than Coronal Plane Measurements for Detecting Syndesmotic Instability
Foot and ankle surgeons at Massachusetts General Hospital determined that, during the arthroscopic evaluation of the distal tibiofibular articulation, sagittal plane fibular translation is more accurate for diagnosing syndesmotic instability than coronal plane diastasis.

Review: Surgical Management of Musculotendinous Balance in Progressive Collapsing Foot Deformity
Philip Kaiser, MD, and Daniel Guss, MD, MBA, foot and ankle surgeons in the Foot and Ankle Center, review the management of muscle and tendon balance in patients with progressive collapsing foot deformity, a new diagnostic entity that subsumes adult-acquired flatfoot deformity and posterior tibial tendon dysfunction.

New Measurement Proposed for Detecting Syndesmotic Instability in 3D
Orthopedic surgeons at Massachusetts General Hospital have developed a clinically applicable, three-dimensional method of assessing syndesmotic (high ankle) instability on weight-bearing CT (WBCT) scans that measures "percentage of change," which is easier than using a numeric scale with an absolute value.
-
Updated Threshold Values Needed for Arthroscopic Diagnosis of Syndesmotic Instability
Based on a systematic review, researchers in Massachusetts General Hospital's Foot and Ankle Research and Innovation Lab believe the commonly used threshold of 2.0 mm for distal tibiofibular diastasis may lead to overdiagnosis of syndesmotic instability during arthroscopy, and they suggest more evidence-based cutoffs.

Gastrocnemius Recession or Tendo-Achilles Lengthening Acceptable for Adult Acquired Flatfoot Deformity Surgery
A systematic review performed by members of the Massachusetts General Hospital Foot & Ankle Research and Innovation Laboratory (FARIL) found that either gastrocnemius recession or tendo-Achilles lengthening is reasonable to include in the surgical treatment of adult acquired flatfoot deformity.
-
Ultrasound Has Potential to Diagnose Subtle Syndesmotic Instability
Members of the Massachusetts General Hospital Foot and Ankle Research and Innovation Laboratory have become the first to demonstrate ultrasound's abilities to evaluate the tibiofibular joint under stressed conditions and show in each individual what normal syndesmotic motion should be.

Open Intermetatarsal Ligament Release Advocated as First Surgical Treatment of Morton's Neuroma
Massachusetts General Hospital researchers observed promising short-term results when recalcitrant Morton's neuroma was treated with simple nerve decompression, without neuroma excision.
-
Weight-bearing CT Useful for Diagnosis of Subtle Syndesmotic Instability
Bilateral weight-bearing CT can distinguish between a stable and unstable distal syndesmosis. This study also emphasizes the importance for the use of the patient's contralateral, uninjured side as their own control.
-
Highly Sensitive Test Identified for Arthroscopic Diagnosis of an Unstable High Ankle Sprain
When evaluating the ankle syndesmosis arthroscopically, a stress maneuver performed in the sagittal plane readily identifies an unstable syndesmosis.
-
Qualitative Side-by-Side Comparison Unreliable for Evaluating Syndesmosis Reduction on CT
With CT scans increasingly used to assess the quality of syndesmotic reduction after destabilizing ankle injuries, subjective comparison of the repaired and uninjured sides to assess the quality of the reduction is unreliable. More quantitative approaches, such as syndesmotic area, result in more accurate assessments.

New Model for Foot and Ankle Research and Innovation
Christopher W. DiGiovanni, MD, chief of Foot and Ankle Service, and Daniel Guss, MD, MBA, orthopaedic surgeon in the Foot and Ankle Center, discuss the innovative work of the Mass General Foot and Ankle Research and Innovation Lab.

Research Advances from Mass General Orthopaedics
Researchers from the Department of Orthopaedics discuss the clinical and translational work they are doing at Massachusetts General Hospital.

Thromboembolic Event After Below-Knee Orthopedic Surgery Quadruples the Risk of Death
Among patients who undergo below-knee orthopedic surgery, symptomatic venous thromboembolism is more common than previously reported and markedly raises the short-term risk of death.
-
MRI Grading of Muscle Proposed as Better Way to Assess Peroneal Tendon Tears
Researchers at Massachusetts General Hospital suggest that instead of focusing solely on the peroneal tendons when torn, we should also focus on the muscle attached to those tendons and the degree of fatty atrophy on preoperative MRI.

Minimally Invasive Foot and Ankle Surgery
Daniel Guss, MD, MBA, discusses the unique roles minimally invasive surgery plays in the Foot and Ankle Center and how minimally invasive surgery speeds up recovery and avoids wound complications.

Novel Technique Developed for Surgical Treatment of Peroneal Tendon Dislocation
Orthopedic surgeons have developed a new technique for preserving the integrity of the fibrocartilage gliding surface and avoiding substantial anatomic disturbance during repair of perineal tendon dislocation.

Injury to Deltoid Ligament Appears Capable of Destabilizing the Syndesmosis
Researchers at Massachusetts General Hospital recently became the first to use arthroscopy to study the effects of deltoid ligament (DL) injury on syndesmotic stability.

Venous Thromboembolism Disease Prophylaxis in Foot and Ankle Surgery
There are numerous society guidelines on how to prevent venous thromboembolism disease in the hip and knee population. Is there any consensus yet for foot and ankle surgery? Massachusetts General Hospital surgeons reviewed the literature to find out.
Biography
Dr. Daniel Guss earned his BS in molecular biophysics & biochemistry at Yale University before attaining his MD at Harvard Medical School. After a year-long general surgery internship at Mass General, he completed the Harvard Combined Orthopaedic Residency Program, training at Harvard-affiliated hospitals including Mass General, Brigham & Women's Hospital, Boston Children's Hospital and Beth Israel Deaconess Medical Center.
Dr. Guss' interest in improving the way our healthcare system delivers care to patients led him to spend two years at Harvard Business School pursuing an MBA, after which he completed a year-long fellowship focused on orthopedic foot and ankle disorders at Brigham and Women's Hospital.
Dr. Guss has a clinical interest in minimally-invasive foot and ankle surgery, foot and ankle reconstruction, sports-related injuries, cartilage, ligament and tendon disorders and orthopedic trauma. He also is actively involved in academic research and teaching.
In his free time, Dr. Guss is an avid downhill skier and has participated in big-mountain ski camps out west. He also enjoys exercising, reading and trying to keep up with his young family.
