Three-dimensional (3-D) printing offers many potential advantages in designing and manufacturing plating systems for foot and ankle procedures that involve small, geometrically complex bony anatomy. Here, we describe the design and clinical use of a Ti-6Al-4V ELI bone plate (FastForward™ Bone Tether Plate, MedShape, Inc., Atlanta, GA) manufactured through 3-D printing processes. The plate protects the second metatarsal when tethering suture tape between the first and second metatarsals and is a part of a new procedure that corrects hallux valgus (bunion) deformities without relying on doing an osteotomy or fusion procedure...

BACKGROUND: Moderate to severe midfoot-forefoot varus deformities are commonly found in several conditions. However, few techniques are available to correct these deformities. So, we evaluated the clinical and radiological outcomes of patients who underwent midfoot derotational osteotomy to achieve plantigrade foot. METHODS: From 2006 to 2014, 6 patients (7 feet) underwent midfoot derotational osteotomy. A visual analog scale (VAS) pain and the American Orthopedic Foot & Ankle Society (AOFAS) functional score were evaluated...

PURPOSE: To date, there is a paucity of literature on syndesmotic reconstruction techniques that restore both anatomic stability and physiologic syndesmotic biomechanics. In this cadaveric study, (1) a novel syndesmotic reconstruction surgical technique using autogenous peroneus brevis tendon was described and (2) the biomechanical properties of the reconstruction was investigated. METHODS: Ten fresh-frozen lower extremities were used in this study. Reconstruction of the anterior and posterior, as well as the interosseous tibiofibular ligaments was performed with a halved peroneus brevis tendon...

BACKGROUND: OnabotulinumtoxinA is approved for the treatment of upper and lower limb spasticity in adults. Guidance on common postures and onabotulinumtoxinA injection paradigms for upper limb spasticity has been developed using a Delphi Panel. However, similar guidance for lower limb spasticity has not been established. OBJECTIVE: To define a clinically recommended treatment paradigm using onabotulinumtoxinA for each common posture among patients with post-stroke lower-limb spasticity (PSLLS); to identify the most common PSLLS aggregate postures...

Our ability to automatically adapt our walking pattern to the demands of our environment is central to maintaining a steady gait. Accordingly, a large effort is being made to extend and integrate this adaptability to lower-limb prostheses. To date, the main focus of this research has been on short term adaptation, such as in response to a terrain transition or a sudden change in the environment. However, long term adaptation and underlying sensorimotor learning processes are critical to optimizing walking patterns and predictively changing our gait when faced with continued perturbations...

Favorable results have been reported for tibialis posterior tendon transfers, which can effectively restore the dorsiflexion of the ankle and normal heel-to-toe gait. However, the commonly used methods for anchoring the transplanted tendon have some drawbacks. Therefore, we developed a new tendon-anchoring method to improve fixation of the transferred tendon and reduce the related complications. The new method entails tying the anchoring suture to the navicular bone instead of the button on the plantar foot to avoid wound complications...

Whitney Ellis-McConnell, Amanda Taylor, Patrick Kelly, Andrew J Meyr
Although the foot and ankle derives its arterial supply from a combination of the anterior tibial artery (ATA), posterior tibial artery (PTA), and peroneal artery (PA), the focus of clinical examination techniques and noninvasive vascular testing is primarily on the ATA and PTA and not on the PA. The objectives of the present investigation were to evaluate the feasibility of incorporating an assessment of the PA into a noninvasive vascular testing protocol and to collect normative data of pressure measurements of the PA at the ankle...

BACKGROUND: Although the clinical assessment of ankle dorsiflexion has traditionally been measured utilising various goniometric means, the validity of this static examination has never been investigated. Since any impairment in ankle flexibility is likely to result in injuries, it is imperative that the correct examination technique is conducted. HYPOTHESIS/PURPOSE: To determine whether a clinical diagnosis of ankle equinus, or limited ankle dorsiflexion, correlates with a decreased dorsiflexion range of movement of the foot and ankle during gait...

Hallux valgus-the most common forefoot deformity-can cause both pain and decreased mobility. The development and progress of the hallux valgus is a multifactorial process. Different intrinsic and extrinsic causes are responsible. Various conservative and operative treatment options exist and have to been chosen regarding the stage of the disease. Conservative orthopedic measures may prevent a deterioration of hallux valgus only at an early stage of the disease. Concerning operative techniques, more than 150 different surgical procedures are described in the literature, which can be reduced to some common procedures...

First metatarsocuneiform joint arthrodesis has been used in foot and ankle surgery for the treatment of hallux abductovalgus deformity, among other pedal pathologic entities. The goal of the present retrospective study was to compare the fusion rates and complications of an intraplate compression screw fixation, crossing solid core screw fixation, and a single interfragmentary screw with a simple locking plate. All procedures were performed by a single surgeon, and all patients received an identical postoperative protocol...

Ultrasound (US) imaging offers significant potential in diagnosis of plantar fascia (PF) injury and monitoring treatment. In particular US imaging has been shown to be reliable in foot and ankle assessment and offers a real-time effective imaging technique that is able to reliably confirm structural changes, such as thickening, and identify changes in the internal echo structure associated with diseased or damaged tissue. Despite the advantages of US imaging, images are difficult to interpret during medical assessment...

Minimally invasive surgery is increasing in popularity. It is relevant in hallux valgus surgery owing to the potential for reduced disruption of the soft tissues and improved wound healing. We present our results and assess the learning curve of the minimally invasive Chevron Akin operation for hallux valgus. A total of 120 consecutive feet underwent minimally invasive Chevron Akin for symptomatic hallux valgus, of which 14 were excluded. They were followed up for a mean of 25 (range 18 to 38) months. The patients were clinically assessed using the American Orthopaedic Foot and Ankle Society score...

REVIEW
Rachel Shakked, Steven Sheskier
Lateral ankle instability is a common entity that can result in degenerative arthritis if left untreated. Acute ligament injuries should primarily be treated nonoperatively with a course of physical therapy and functional bracing. Chronic ankle instability is defined as mechanical or functional and can be diagnosed using a combination of history, physical examination, stress radiographs, and magnetic resonance imaging. After failure of nonoperative treatment, surgical treatment with anatomic ligament repair and inferior extensor retinaculum augmentation has the best clinical outcomes...

INTRODUCTION: Distal fibula fractures are common orthopaedic injuries that often require open reduction internal fixation (ORIF) to anatomically reduce the fracture and minimize the risk of posttraumatic arthritis. In certain clinical situations, stouter fixation may be advantageous to decrease the risk of fixation failure. In this study, the authors report on 12 patients who underwent distal fibula ORIF with 2 one-third tubular plates. MATERIALS AND METHODS: Twelve consecutive patients who underwent distal fibula ORIF with 2 one-third tubular plates were retrospectively reviewed...
