Bone SPECT/CT in the Evaluation of Painful Total Ankle Replacement: Validation of Localization Scheme and Preliminary Evaluation of Diagnostic Patterns.

Purpose: Third-generation total ankle replacement (TAR) is an increasingly popular and effective treatment for end-stage osteoarthritis, yet identifying causes of failure remains challenging. We evaluated integrated bone SPECT/CT in recurrent pain after TAR by validating a standardized reporting scheme, identifying uptake patterns, and assessing diagnostic performance and impact on clinical management.

Patients And Methods: A total of 24 TARs in 16 patients with persistent or recurrent pain received integrated bone SPECT/CT using diagnostic CT settings.

Clinical and Radiological Outcomes of Hallux Rigidus Treated With Cheilectomy and a Moberg-Akin Osteotomy.

Background: This study aimed to evaluate the clinical and radiological outcome after cheilectomy and proximal phalangeal biplanar osteotomy for patients with mild and advanced stages of hallux rigidus.

Methods: A total of 105 feet (grades 0-4) were treated with cheilectomy and a Moberg-Akin osteotomy of the proximal phalanx. All patients were clinically assessed preoperatively and followed up for 12 months by range of motion, visual analog scale (VAS) pain score, American Orthopaedic Foot & Ankle Society (AOFAS) score, Short Form 36 (SF-36) score, and weightbearing radiographs.

Lower Extremity Near-infrared Spectroscopy After Popliteal Block For Orthopaedic Foot Surgery.

Background: Noninvasive measurement of cutaneous tissue oxygenation using near-infrared spectroscopy (NIRS) has become common in peri-operative care. Following institution of peripheral nerve blocks, neurovascular alterations in the blocked region have been described.

Objective: The primary aim of this study encompassed the assessment of the influence of a popliteal block on changes in regional oxygen saturation (SrO2), and the location of most prominent changes.

Intratest reliability in determining the subtalar joint axis using the palpation technique described by K. Kirby.

Background: Exact determination and classification of the spatial position of the subtalar joint axis could be a predictive clinical variable in biomechanical analysis and a valuable tool in the design of functional foot orthoses.

Methods: Three clinicians with different levels of experience determined and classified the subtalar joint axis location, three times, on 52 individuals, using the clinical palpation, allocation and interpretation technique, as described by K. Kirby.
