Laser-Guided Intraoperative Navigation in Total Ankle Replacement Surgery.

Background: This study aimed to evaluate the effectiveness of laser-guided intraoperative navigation compared with the conventional method in determining the accuracy of coronal alignment setting in total ankle replacement (TAR).

Material And Methods: Sixteen cadaveric ankles were randomly divided into two groups: laser-guided and conventional. Measurements were performed following coronal alignment setting in each ankle.

Total talar prosthesis with and without ankle ligament reconstruction using the three-dimensional computer-aided design and computer numerical control manufacturing techniques.

Severe damage and bone loss of the talus are problematic issues because of its unique shape, function, and characteristics. This present study's objective is to propose the process of customized total talar prosthesis manufacturing, using three-dimensional (3D) Computer-Aided Design (CAD) with Computer Numerical Control (CNC) production along with evaluation of the results of total talar prosthesis replacement with or without ankle ligament reconstruction in patients with severe conditions of talus. The case series included five patients (mean age: 27.

Minimally invasive surgery versus an arthroscopic procedure for the first metatarsophalangeal arthrodesis: A comparative study of the effectiveness and safety profile.

Introduction: First metatarsophalangeal (MTP) arthrodesis is a common procedure for treating degeneration in the MTP joint. Open arthrodesis is a conventional procedure that provides acceptable results but is more invasive than minimally invasive or arthroscopic arthrodesis. However, little is known about the different outcomes between minimally invasive surgery (MIS) and arthroscopic surgery (AS) for MTP arthrodesis.

Morphometric geometric differences between right and left human tali: A cadaveric study of fluctuating asymmetry via systematic measurement and three-dimensional scanning.

Background: Little is known about differences in the size and morphology of the right and left human tali. The present study demonstrates differences between right and left talar morphometric geometric profiles as fluctuating asymmetry in matched pairs of cadaveric specimens.

Methods: In total, 24 tali were collected in this study.

Talar-sided osteochondral lesion of the subtalar joint following the intra-articular calcaneal fracture: study via a modified computed tomography mapping analysis.

Introduction: This study is to report the prevalence of osteochondral lesions in subtalar joint following intra-articular calcaneal fracture, including the relationship between fracture severity and lesion characteristics, using modified computed tomography (CT) mapping analysis.

Methods: Thirty patients with intra-articular calcaneal fracture who were preoperatively imaged with modified CT mapping analysis were recruited. The presence of talar-sided osteochondral lesions (OLTS) of subtalar joint was noted with lesion area defined by Akiyama's mapping classification.

Peroneal Tendoscopic Debridement and Endoscopic Groove Deepening in the Prone Position.

Tendoscopy of the peroneal tendon is a promising procedure for the treatment of peroneal tendon pathology and its disorders. This procedure is minimally invasive with less physical morbidity and early functional rehabilitation. The present report demonstrates the techniques of peroneal tendoscopic debridement and endoscopic groove deepening in the prone position to treat peroneal tenosynovitis and low-lying muscle belly of peroneus brevis with a shallow and flat surface of the retro-malleolar groove.
