Computed-tomography-based three-dimensional analysis of bilateral differences in phalanges.

Three-dimensional analysis of bones, especially for preoperative planning of corrective osteotomy in fracture malunion, assumes that the bilateral extremities exhibit a symmetrical mirror image when projected onto each other. No studies are available for phalanges. Three-dimensional bone models of all phalanges of 20 healthy participants (40 hands) were created from computed tomography data.

The use of ultrasound to predict flexor tendinopathy after anterior locking plating of the distal radius.

This study compares ultrasound to clinical and radiographic measurements for assessing tendon pathology associated with distal radial anterior locking plates. A total of 46 patients undergoing removal of a distal radial plate had a preoperative clinical examination, radiographs and ultrasound evaluation to detect evidence of tendon irritation. Gross changes to the tendon were assessed during plate removal.

Gastroesophageal reflux after per oral endoscopic myotomy for achalasia: Results of a monocentric cohort.

Background And Study Aims: Peroral endoscopic myotomy (POEM) has become the first line treatment for achalasia, but controversies remain about the prevalence of gastro-esophageal reflux disease (GERD) after the procedure. The aim of this study was to evaluate post-POEM GERD by a retrospective analysis of a single center cohort.

Patients And Methods: Achalasia patients aged 18 or above, who underwent POEM between 2012 and 2021, were included, provided they had an endoscopic control of reflux at least one year after POEM.

Computer-assisted correction of incongruent distal radioulnar joints in patients with symptomatic ulnar-minus variance.

Our study described a computer-assisted, three-dimensional (3-D), planned surgical technique of a radial shortening osteotomy. The osteotomy of the distal radius was planned with computer assistance on 3-D bone models based on computed tomography data. The objective was to maximize the contact zone of the sigmoid notch with the ulnar head.

Clinical, radiological and patient-rated outcome comparison between total and partial ulnar head implants.

This study aimed to analyse the clinical and radiological outcomes after ulnar head replacement and to compare partial and total ulnar head implants. Twenty-two patients with 23 implants were available with a mean follow-up time of 7 years (range 1.3 to 17) after distal radioulnar joint arthroplasty.
