Osteochondral Lesions of the Talus: Evaluation of Risk Factors and Their Impact on Postoperative Outcomes.

Osteochondral lesions of the talus (OLT), also known as talar osteochondritis dissecans, is minor fracture to the articular cartilage of the talas subchondral bone it is associated with. The literature regarding its impact on patient demographics on post-operative associations of OLT-related repairs is lacking. The American College of Surgeons National Surgical Improvement Program (NSQIP) database was retrospectively reviewed, collecting data on patients with an OLT procedure between the 2008 through 2016.

Comparison of Risk Factors and Postoperative Outcomes in Syndesmosis Injuries with Various Ankle Fracture Types.

There is a lack of understanding of risk factors and postoperative outcomes of syndesmotic injuries with singular versus multipart fractures. A retrospective analysis was done between 2008 and 2016, utilizing the American College of Surgeons National Surgical Improvement Program database. Patients with open reduction and internal fixation of isolated lateral malleolus fractures, bimalleolar fractures, or trimalleolar fractures were identified.

Evaluating success rate and comparing complications of operative techniques used to treat chronic syndesmosis injuries.

Purpose: To assess the success rate and complications of the surgical interventions used to manage chronic syndesmosis injuries.

Methods: Multiple online databases were queried to identify studies reporting operative intervention for chronic syndesmosis injuries.

Results: Modalities of operative fixation include suture-button fixation, arthroscopy and debridement, as well as arthrodesis.

Ankle Fracture Epidemiology in the United States: Patient-Related Trends and Mechanisms of Injury.

Current nationwide epidemiological data regarding ankle fractures are scarce. Such information is important towards better quantifying the mortality associated with such injuries, financial impact, as well as the implementation of preventative measures. This study evaluated the epidemiology of ankle fractures that occurred during a 5-year period.

Rotational Deformity of the First Ray Precludes Accurate Distal Metatarsal Articular Angle Measurement in Hallux Valgus.

The routine workup of hallux valgus includes measurements of the distal metatarsal articular angle (DMAA). However, this angle may not be a reliable measurement when rotational deformities occur. Eight matched cadaveric feet were evaluated radiographically using fluoroscopy.

A Biomechanical Comparison of Different Tendon Repair Techniques.

Previous studies have examined multiple suture techniques for the repair of ruptured tendons. In this study, we investigated how the two- and four-stranded Krackow suture weave techniques compared with a novel Krackow/Bunnell suture technique. Our hypothesis was that the Krackow/Bunnell suture would have greater strength compared with the two- and four-stranded Krackow suture in terms of resistance to pullout from the muscle tendon.

Strength of Syndesmosis Fixation: Two TightRope versus One TightRope with Plate-and-Screw Construct.

Injuries involving the distal tibiofibular syndesmosis can lead to critical destabilization of the ankle mortise. Although specific indications for operative fixation remain unclear, accurate reduction of the syndesmosis has been correlated with the best functional outcomes. The purpose of this study was to evaluate the maximum torque and rotation to failure after fixation with a novel construct.

Biomechanical evaluation of varying the number of loops in a repair of a physiological model of Achilles tendon rupture.

Background: Numerous suturing techniques have been described to treat Achilles tendon ruptures. No prior studies have evaluated frayed tendon ends on construct strength and whether this allows for less extensile exposure.

Methods: Forty bovine Achilles tendons were divided into groups: 1 control and 4 experimental.
