Interdigital vs Transarticular Lateral Release With Scarf Osteotomy.

Background: We compare the clinical and radiographic outcomes of the interdigital approach vs the medial transarticular approach for lateral release combined with scarf osteotomy.

Methods: Seventy-seven feet with moderate to severe hallux valgus underwent scarf osteotomy and lateral soft tissue release, using an interdigital approach (n = 36) vs medial transarticular approach (n = 41). The clinical measurements (range of motion, American Orthopaedic Foot & Ankle Society [AOFAS] score) and radiographic data were evaluated preoperatively and at final follow-up (93-124 months postoperatively).

Sources and Toxicity of Mercury in the San Francisco Bay Area, Spanning California and Beyond.

This report synthesizes and evaluates published scientific literature on the environmental occurrence and biomagnification of mercury with emphasis on the San Francisco Bay Area (SFBA), California. Mercury forms various compounds, well known for their toxicity in humans and environmental ecosystems. Elemental mercury is transported and distributed by air, water, and sediments.

Reliability of ultrasonography measurement of the anterior talofibular ligament (ATFL) length in healthy subjects (in vivo), based on examiner experience and patient positioning.

Background: The most common cause of ankle injury is the supination trauma, inflicting a partial or complete rupture of the anterior talofibular ligament (ATFL). Among conventional diagnostic tools and procedures of sports injuries, the method of stress-ultrasonography is reportedly a promising diagnostic tool for examining injuries of the lateral ligaments of the ankle. Preceding studies predominantly examined the comparability of stress-ultrasonography and other established diagnostic tools in terms of efficacy, viability and quality.

The Scarf Osteotomy with Minimally Invasive Lateral Release for Treatment of Hallux Valgus Deformity: Intermediate and Long-Term Results.

Background: Little is known about the long-term results of surgical correction of hallux valgus deformity, in particular, the recurrence rate and factors leading to recurrence.

Methods: Of one hundred and eight patients (115 feet) who underwent a Scarf osteotomy, ninety-three patients (ninety-three feet) were examined at an average duration of follow-up of 124 months. Clinical examination before surgery and at the time of final follow-up included an evaluation of range of motion, pain as measured with a visual analog scale, and American Orthopaedic Foot & Ankle Society (AOFAS) scores.

Imaging of posterior tibial tendon dysfunction--Comparison of high-resolution ultrasound and 3T MRI.

Purpose: Posterior tibial tendon dysfunction is the most common cause of acquired asymmetric flatfoot deformity. The purpose of this study was to determine and compare the diagnostic value of MRI and high-resolution ultrasound (HR-US) in posterior tibial tendon dysfunction (PTTD), and assess their correlation with intraoperative findings.

Materials And Methods: We reviewed 23 posterior tibial tendons in 23 patients with clinical findings of PTTD (13 females, 10 males; mean age, 50 years) with 18MHz HR-US and 3T MRI.
