Biomechanical comparison of suture-button,bioabsorbable screw,and metal screw for ankle syndesmotic repair: A meta-analysis

BackgroundTo compare biomechanically metal screw fixation to suture-button or bioabsorbable screw fixation for ankle syndesmotic injuries.MethodsA literature search of the comparison studies in Pubmed and Google Scholar was conducted. The biomechanical outcomes of interest were syndesmotic stability in the coronal, sagittal, and axial planes as well as torque and rotation at failure.ResultsA total of 11 cadaveric studies were included. In the suture-button group, coronal displacement (MD 1.72 mm, p = 0.02) and sagittal displacement (MD 2.65 mm, p = 0.0003) were increased relative to the metal screw group. In contrast, no difference was found with axial rotation (MD 0.35 degrees, p = 0.57). Bioabsorbable screws exhibited equivalent failure torque (MD ?3.04 Nm, p = 0.53) and rotation at failure (MD 3.77 degrees, p = 0.48) in comparison to metal screws.ConclusionsSuture-button provide less rigidity when compared to metal screw fixation. They afford flexible syndesmotic micromotion which may more closely resemble a physiological state and be helpful for ligament healing. Bioabsorbable screws demonstrate similar mechanical strength properties to metal screws.     

New technology and techniques in the treatment of foot and ankle injuries

The advancement of new technologies in the treatment of foot and ankle injuries seems exponential over the last several years. As surgeons expand their knowledge of the pathology and improve their treatment techniques, they come upon new and different ways to treat the same pathologic conditions. Foot and ankle injuries are commonplace in competitive sports. This article provides an overview of the diagnosis and treatment, including surgical techniques, of common foot and ankle injuries.     

Management of syndesmotic injuries:What is the evidence?

Ankle fractures are accompanied by a syndesmotic injury in about 10% of operatively treated ankle fractures. Usually, the total rupture of the syndesmotic ligaments with an external rotation force is associated with a Weber type B or C fracture or a Maisonneuve fracture. The clinical assessment should consist of a comprehensive history including mechanism of injury followed by a specific physical examination. Radiographs, and if in doubt magnetic resonance imaging, are needed to ascertain the syndesmotic injury. In the case of operative treatment the method of fixation, the height and number of screws and the need for hardware removal are still under discussion. Furthermore, intraoperative assessment of the accuracy of reduction of the fibula in the incisura using fluoroscopy is difficult. A possible solution might be the assessment with intraoperative three-dimensional imaging. The aim of this article is to provide a current concepts review of the clinical presentation, diagnosis and treatment of syndesmotic injuries.     

Syndesmosis injuries

Traumatic injuries to the distal tibiofibular syndesmosis commonly result from high-energy ankle injuries. They can occur as isolated ligamentous injuries and can be associated with ankle fractures. Syndesmotic injuries can create a diagnostic and therapeutic challenge for musculoskeletal physicians. Recent literature has added considerably to the body of knowledge pertaining to injury mechanics and treatment outcomes, but there remain a number of controversies regarding diagnostic tests, implants, techniques, and postoperative protocols. Use of the novel suture button device has increased in recent years and shows some promise in clinical and cadaveric studies. This article contains a review of syndesmosis injuries, including anatomy and biomechanics, diagnosis, classification, and treatment options.     

TightRope带袢钛板系统治疗肩锁关节脱位的疗效

Index metacarpal fracture after tightrope suspension following trapeziectomy: case report

Trapeziectomy, by itself or combined with ligament reconstruction/interposition arthroplasty, is commonly performed for advanced trapezial-metacarpal arthritis. Several methods and materials, both autogenous and artificial, are commonly used for ligament reconstruction and interposition arthroplasty. Harvesting autologous tendons adds to operative time and could increase potential surgical complications. Using an artificial material would, in theory, avoid some of these problems. However, this approach is not without its problems. We present a case of index metacarpal fracture after using the Arthrex Mini TightRope (Arthrex, Naples, FL) suture button fixation of the thumb and index metacarpals after complete trapeziectomy.
