Traditional postero-medial ankle approach for Bartonícek type III in Volkmann Fractures: Is it useful?

Introduction: There is evidence that the presence of a posterior malleolus fracture (PMF) worsens the prognosis of ankle fractures, making conservative treatment a poor choice. PMFs include a heterogeneous group of bone injury patterns that are sometimes associated to medial malleolus extensions, as well as fibula fractures or syndesmotic damage. This requires the surgeon to be well-versed in anatomy to choose the appropriate surgical approach.

Anatomical analysis of the traditional postero-medial approach to the ankle and evaluation of structures at risk.

Introduction: The presence of a fracture of the posterior malleolus gives a poor prognosis for ankle fractures. This study aimed to analyze the anatomical structures at risk in the traditional postero-medial (TPM) approach.

Methods: Of a total of 21 cadaveric pieces, 11 were female and 10 were male; 9 ankles/right foot and 11 ankles/left foot.

Arthrodesis vs arthroplasty for moderate and severe Hallux rigidus: Systematic review.

Unlabelled: Hallux rigidus is the most frequent arthritis of the foot, due to multiple factors. Arthrodesis and interposition arthroplasty are treatments considered in advanced stages of the disease, when conservative treatment has failed. Although arthrodesis may be considered the technique recommended by multiple authors, for patients in whom joint mobility is to be preserved, arthroplasty could represent a reliable alternative.

Hallux Valgus: The Influence of Intersesamoid Crista's Osteoarthritis on Frontal Plane Pronation.

A frontal plane metatarsal rotational (pronation) has been documented in a high percentage of hallux valgus patients. Pathoanatomical concepts leading to pronation are still debated. Nevertheless, there is no consensus on how to measure this component of the deformity.

Methods: Between June 2017 and July 2019, this procedure was performed on 8 feet (8 patients; mean age, 55 [42-70] years; mean BMI, 29.

Anatomy of the Dorsomedial Cutaneous Nerve to Hallux and Surgical Implications According to the Severity of Hallux Valgus Deformity: A Cadaveric Study.

The dorsomedial cutaneous nerve to hallux provides sensation to the dorsomedial aspect of the first metatarsophalangeal joint and hallux. Postoperative damage to the dorsomedial cutaneous nerve to hallux have been reported with the dorsomedial approach and symptoms can be very debilitating. The present study aims to understand how the distance between this nerve and the extensor hallucis longus tendon are affected by the severity of the hallux valgus deformity, at the level of the first metatarsophalangeal joint.

Osteosynthesis or primary arthrodesis for displaced intra-articular calcaneus fractures Sanders type IV - A systematic review.

Background: Displaced intra-articular calcaneus fractures (DIACF) Sanders type IV represent a challenge in its management and questions remain about the best treatment option available. This study aimed to compare the outcomes of primary subtalar arthrodesis (PSTA) and osteosynthesis in these fractures.

Methods: Studies concerning DIACF Sanders type IV, from 2005 to 2020 were systematically reviewed.

Three-dimensional analysis of anterior talofibular ligament strain patterns during cadaveric ankle motion using a miniaturized ligament performance probe.

Background: Measuring the strain patterns of ligaments at various joint positions informs our understanding of their function. However, few studies have examined the biomechanical properties of ankle ligaments; further, the tensile properties of each ligament, during motion, have not been described. This limitation exists because current biomechanical sensors are too big to insert within the ankle.

Complications on Percutaneous Hallux Valgus Surgery: A Systematic Review.

Lately there has been a growing interest in the use of percutaneous surgery for the correction of hallux valgus (HV). The purpose of the present study was to systematically review the published data about this topic and establish the efficacy and safety, stressing the complication rates found on this percutaneous technique. A systematic review of the literature available in PubMed was performed.

Aseptic (avascular) bone necrosis in the foot and ankle.

Aseptic necrosis may be defined as a group of diseases that have bone necrosis as a common denominator. They usually appear in the epiphyses and in the carpal and tarsal bones. They generally appear during a growth period and principally at those skeletal points subjected to particular stress.
