Comparison of the diagnostic value of measurements of transverse syndesmotic interval and 'lambda sign' in distinguishing latent syndesmotic diastasis in chronic lateral ankle instability: a cross-sectional study of 188 cases.

Arch Orthop Trauma Surg 2022 Jun 21. Epub 2022 Jun 21.

Radiology Department, Peking University Third Hospital, No.49 North Garden Road, Haidian, Beijing, 100191, China.

Introduction: Chronic lateral ankle instability (CLAI) could accompany with latent syndesmotic diastasis (LSD), which is difficult to distinguish before surgery. Tibiofibular interval width and extravasation of joint fluid ('lambda sign') on MRI are widely used in the diagnosis of syndesmotic injury, but the reliability of these methods in distinguishing the associated LSD in CLAI was rarely studied. Our objective was to compare the diagnostic value of the measurement of the transverse tibiofibular interval and 'lambda sign' on MRI in distinguishing LSD in CLAI and to investigate the radiological predictor that best matched the intraoperatively measured syndesmotic width.

Surgical Anatomy for Fibular Free Flap Focusing on the Inferior Tibiofibular Syndesmotic System: A Cadaveric Study and Case Series of 3-Dimensional Prefabricate Cutting Guided Fibular Free Flap.

J Craniofac Surg 2022 May 26;33(3):951-955. Epub 2021 Oct 26.

Division of Plastic and Reconstructive Surgery, Department of Surgery.

Abstract: Even though there are many options for mandibular reconstruction, a free fibula osteocutaneous flap is regarded as the most frequently used flap. Despite having some previous anatomical studies pertaining to syndesmotic ligaments, there is no study pointing out that surgical landmarks can be used while free fibula osteocutaneous flaps are performed and used for surgical landmarks in order to avoid syndesmotic ligament injuries. Therefore, this study investigates the characteristics and relationship between inferior syndesmotic ligaments and fibula in cadavers. Read More

Which Functional Tests and Self-Reported Questionnaires Can Help Clinicians Make Valid Return to Sport Decisions in Patients With Chronic Ankle Instability? A Narrative Review and Expert Opinion.

Front Sports Act Living 2022 26;4:902886. Epub 2022 May 26.

French Society of Sports Physical Therapist (SFMKS Lab), Pierrefitte-sur-Seine, France.

Lateral ankle sprain is the most common injury in sports, with up to 40% of patients developing chronic ankle instability (CAI). One possible cause underlying this high rate of recurrence or feeling of giving way may be a premature return to sport (RTS). Indeed, except for time-based parameters, there are no specific criteria to guide clinicians in their RTS decisions in patients with CAI. Read More

Role of the Contra-Lesional Corticoreticular Tract in Motor Recovery of the Paretic Leg in Stroke: A Mini-Narrative Review.

Front Hum Neurosci 2022 26;16:896367. Epub 2022 May 26.

Department of Physical Medicine and Rehabilitation, College of Medicine, Yeungnam University, Taegu, South Korea.

This review discusses the role of the contra-lesional corticoreticular tract (CRT) in motor recovery of the paretic leg in stroke patients by reviewing related diffusion tensor tractography studies. These studies suggest that the contra-lesional CRT can contribute to the motor recovery of the paretic leg in stroke patients, particularly in patients with complete injuries of the ipsilesional corticospinal tract and CRT. Furthermore, a review study reported that the motor recovery of the paretic ankle dorsiflexor, which is mandatory for achieving a good gait pattern without braces in hemiparetic stroke patients, was closely related to the contra-lesional CRT.

Douglas H Richie

Clin Podiatr Med Surg 2022 Jul;39(3):461-476

California School of Podiatric Medicine at Samuel Merritt University, 450 30th Street Suite 2860, Oakland, CA 94609, USA. Electronic address:

The fibrocartilage within the superomedial calcaneonavicular (spring) ligament is part of an interwoven complex of ligaments that span the ankle, subtalar, and talonavicular joints. Acute isolated rupture of the spring ligament has been reported in association with an eversion ankle sprain. Attenuation and failure of the spring ligament causes complex 3D changes called the progressive collapsing foot deformity (PCFD). Read More

Fibrocartilaginous Tissue: Why Does It Fail to Heal?

Clin Podiatr Med Surg 2022 Jul;39(3):437-450

Division of Podiatry, Department of Surgery, Beth Israel Deaconess Medical Center, 185 Pilgrim Road, Span 3, Boston, MA 02215, USA.

Tendons and ligaments are critical components in the function of the musculoskeletal system, as they provide stability and guide motion for the biomechanical transmission of forces into bone. Several common injuries in the foot and ankle require the repair of ruptured or attenuated tendon or ligament to its osseous insertion. Understanding the structure and function of injured ligaments and tendons is complicated by the variability and unpredictable nature of their healing. Read More

Normal and Diseased Imaging: Ultrasound/MRI.

Clin Podiatr Med Surg 2022 Jul;39(3):421-435

Stamford Health Medical Group, 800 Boston Post Road, Suite 302, Darien, CT 06820, USA.

The lesser metatarsophalangeal joint plantar plate and calcaneonavicular (spring) ligament are highly specialized soft tissue structures within the foot, consisting partly of fibrocartilage and capable of withstanding high compressive and tensile loads. Preoperative advanced imaging, in the form of point-of-care ultrasound and MRI, has become indispensable for surgeons hoping to confirm, quantify, and better localize injuries to these structures before surgery. This article describes the technical considerations of ultrasound and MRI and provides examples of the normal and abnormal appearances of these structures. Read More

Respective Contributions of Instrumented 3D Gait Analysis Data and Tibial Motor Nerve Block on Presurgical Spastic Equinus Foot Assessment: A Retrospective Study of 40 Adults.

Front Neurol 2022 27;13:862644. Epub 2022 May 27.

Department of Physiological Explorations, University Hospital of Toulouse, Toulouse, France.

Spastic equinus foot is a common deformity in neurologic patients who compromise walking ability. It is related to the imbalance between weak dorsiflexion and overactive plantar flexor muscles. To achieve the best functional results after surgical management, the challenge is to identify the relevant components involved in the deformity using several methods, namely, examination in the supine position, motor nerve blocks allowing transient anesthesia of suspected overactive muscles, and kinematic and electromyographic data collected during an instrumented 3D gait analysis.
