Morphology of the dorsal and lateral calcaneocuboid ligaments.

2008

Background: The dorsolateral calcaneocuboid ligaments have different configurations. In the literature they are only described as either the dorsal or lateral calcaneocuboid ligament. However, recent reconstructive surgical techniques may benefit from a better understanding of the anatomy. The aims of this study were to classify the morphology and attachments of the dorso-lateral calcaneocuboid ligaments and to determine their dimensions. Materials and Methods: The dorso-lateral aspects of the calcaneocuboid joint of 30 cadaver feet were dissected to expose the associated ligaments. Further, we evaluated possible bony landmarks of the calcaneus that could imply which shape or course the li…

Detecting Ankle Instability With an Instrumented Ankle Arthrometer: An Experimental Study.

2019

A new instrumented device was developed to quantify ankle joint stability during an anterior talar drawer test. The aim of the present study was to validate this device comparing bone kinematics with arthrometer measurement outcomes. An anterior talar drawer test was performed with 14 cadaver legs using a custom instrumented ankle arthrometer. Using clusters of bone-pin markers, the relative three-dimensional movement of calcaneus, talus, and fibula was simultaneously measured. Anterior drawer test was applied on the intact foot and after sequentially sectioning the anterior talofibular ligament, the calcaneofibular ligament, and the posterior talofibular ligament. Cutting the anterior talo…

Periosteal repair of the dorsal calcaneocuboid ligament: a comparative biomechanical study.

2007

Background: Isolated lateral calcaneocuboid joint instability rarely is described. Missed or delayed diagnosis resulting in inadequate treatment may lead to chronic instability, followed by sports inability and handicap in daily life. Besides arthrodesis, anatomic repair augmenting the elongated dorsal calcaneocuboid ligament with a local periosteal flap has recently been described for treatment. Methods: In a controlled laboratory study, eight isolated fresh-frozen human cadaver calcaneocuboid specimens were strained in a varus direction until failure of the dorsal calcaneocuboid ligaments. Then the dorsal calcaneocuboid ligaments were reconstructed with free periosteal flaps and tensile …

Comparison of endoscopic and open resection for Haglund tuberosity in a cadaver study.

2006

Background: About half of patients who have Haglund disease may require treatment by surgical resection of the superior portion of the calcaneal tuberosity. Endoscopic techniques have been described as alternatives to open surgery, but only results of uncontrolled retrospective clinical investigations have been reported. Up to now no research is available which compares these different procedures. Methods: A controlled laboratory study was done to evaluate the morphologic appearance of the superior portion of the calcaneal tuberosity after endoscopic or open resection. The tuberosity was resected in 15 isolated fresh-frozen human cadaver lower limb specimens with either open (nine) or endos…

Stabilizing lateral ankle instability by suture tape - a cadaver study.

2019

Abstract Background Suture tape is a recent development to augment a Brostrom repair at least during the healing phase of the native tissues used for stabilization of the lateral ankle ligaments. The purpose of this study was to evaluate whether suture tape is an effective mechanical stabilizer against anterior talar drawer in a cadaver experiment when tested with a validated arthrometer. Methods Different stability conditions were created in 14 cadaveric foot and leg specimens. Following anterior talofibular ligament (ATFL) dissection, isolated suture tape ATFL reconstruction was compared to the unaltered specimens, to the condition with ATFL cut, to the ATFL plus calcaneofibular ligament …
