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. GERD symptoms based on GerdQ questionnaire, and proton pomp inhibitors (PPI) consumption were also evaluated., Results: Among a consecutive cohort of 422 patients treated by POEM, 254 patients were included. Endoscopic results were available after a mean follow-up of 1.9 ± 1.5 years. 71/254 patients (28 %) had erosive esophagitis (86 % Los Angeles Grade A or B). At the last follow-up (mean 4.5 ± 2.2 years), clinical success of POEM (Eckardt score ≤ 3) was achieved in 79.5 % of patients. 44.5 % of patients were on PPI. Mean GerdQ score was 2.2 ± 2.7, with only 13 patients (6.5 %) with a score ≥ 8., Conclusion: In this cohort of achalasia patients with an endoscopic follow-up at least 1 year after POEM, GERD did not appear a major threat concern: clinical symptoms were mild in most cases, as was the degree of erosive esophagitis. Furthermore, at the time of last follow up, less than half of patients required treatment with PPI., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

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. In total, 32 patients demonstrated clinical abnormality. Soong 2 position was noted in 13 patients. Ultrasound revealed tenosynovitis in nine patients, tendon fibrillation or thickening in four patients and a single case of partial discontinuity. Intraoperative assessment revealed tenosynovitis in 28 patients and tendon fibre discontinuity in eight patients. Ultrasound findings were not predictive of intraoperative tenosynovitis and discontinuity. A relationship was noted between higher Soong grade, especially grade 2, and intraoperative presence of tenosynovitis, as well as Soong grade and amount of soft-tissue coverage. This study negates our hypothesis that ultrasound is useful for identifying tendinopathy after distal radial anterior plate fixation.

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. Between 2012 and 2020 we treated 14 wrists in 11 patients with symptomatic ulnar-minus variance with a mean follow-up of 44 months (range 8 to 98) and a mean age of 28 years (range 19 to 38). Postoperatively, patients showed a decrease in pain at rest and during effort (numeric rating scale from 4.4 to 0 and 7.5 to 4.5, respectively). The range of motion postoperatively was similar to the contralateral side. Grip strength increased from 24 kg to 30 kg. The Disability of the Arm, Shoulder, and Hand and the Patient-Rated Wrist Evaluation scores were 28 and 35 postoperatively, respectively. Our technique of 3-D computer-assisted distal radioulnar joint reconstruction led to a pain reduction and improvement of the hand function in patients with symptomatic ulnar-minus variance. Level of evidence: IV.

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. At the final follow-up, patients had a low level of pain at rest and during effort, a median Disabilities of the Arm, Shoulder, and Hand (DASH) score of 12 and Patient-Rated Wrist Evaluation score of 12 with partial ulnar head implants, and scores of 20 and 22 in total ulnar head implants, respectively. While the range of motion in patients with partial ulnar head implants was slightly reduced in comparison with the preoperative condition and to the patients with total ulnar head implants, there was a tendency to a higher grip strength and rotational torque. Both types of prosthesis showed sigmoid notch resorptions and resorptions around the neck. We conclude that the results after partial ulnar head replacement do not significantly differ from the total ulnar head implants in many aspects. Level of evidence: III.

The Sauvé-Kapandji procedure is an established treatment option for distal radioulnar joint dysfunction. We retrospectively analysed 36 patients following Sauvé-Kapandji procedure between 1997 and 2013. Fifteen patients were available for a follow-up after a mean of 13 years (range 6 to 23). Six patients needed revision surgery because of ulnar stump instability. Radiographs and sonography were performed to quantify the instability of the proximal ulnar stump. These showed a radioulnar convergence of 8 mm without weight and 2 mm while lifting 1 kg. Sonographically, the proximal ulnar stump dislocated by 8 mm to the volar side while applying pressure to the palm, compared with 4 mm on the contralateral side. Sonographically measured ulnar stump instability showed a positive strong correlation with the Disabilities of the Arm, Shoulder and Hand questionnaire and Patient-Reported Wrist Evaluations and a negative strong correlation with grip strength and supination torque. Because of the high incidence of revision surgery due to instability of the proximal ulnar stump, we restrict the use of the Sauvé-Kapandji procedure only to very selected cases. Level of evidence: IV.

We report a rare yet typical presentation of a severe infection with Mycobacterium marinum that affected the deep structure of the hand and wrist of a 43-old fish breeder. A combination therapy of surgical debridement and antibiotic treatment with clarithromycin and ethambutol for 6 months led to a total resolution of the symptoms. Intensive rehabilitation completely restored the function of the hand., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019. No commercial re-use.

Background: Literature provides little and controversial evidence regarding the influence of ulnar variance (UV) on the incidence of scaphoid fractures. The aim of this retrospective study was to assess UV in a large number of patients with acute scaphoid fracture in comparison to a control group of the same population., Methods: During a two year period, 182 patients with acute scaphoid fractures (fracture group) and 182 ethnicity-, gender- and age-matched patients with wrist contusions (control group) were treated in three non-university hospitals. Using standardized digital wrist radiographs, UV values were measured by means of the method of perpendiculars by two independent examiners. The UV values of the fracture group were then compared to the UV values of the control group., Results: Analyses of the agreement between the two raters resulted in a good to excellent inter-item correlation of 0.89, with a high intra-class coefficient of 0.93 (95% confidence interval: 0.87-0.95). Mean (SD) UV value was -0.82 mm (1.77) in the fracture group and 0.27 mm (1.44) in the control group. Paired sample t-test showed a significant difference between the two groups (p < 0.0001)., Conclusions: According to this study, patients with scaphoid fractures are significantly more likely to show a negative UV than matched patients with wrist contusions.

The hypothenar hammer syndrome (HHS) is a rare entity of secondary Raynaud's phenomenon. The blunt hypothenar trauma causes a lesion of the vessel wall with a consecutive thrombosis or aneurysm of the ulnar artery at the Guyon's canal. Different risk factors are discussed such as nicotine abuse, or a muscle anomaly in the Guyon's canal. To date, there are five case reports published about muscle anomalies and HHS. We present a case of a 51-year-old shipbuilder with a unilateral HHS on his right dominant hand with a bilateral muscle anomaly. We successfully treated the patient by resection of the aneurysm without a resection of the atypical muscle.

Focal onset epilepsies most often occur in the temporal lobes. To improve diagnosis and therapy of patients suffering from pharmacoresistant temporal lobe epilepsy it is highly important to better understand the underlying functional and structural networks. In mesial temporal lobe epilepsy (MTLE) widespread functional networks are involved in seizure generation and propagation. In this study we have analyzed the spatial distribution of hemodynamic correlates (HC) to interictal epileptiform discharges on simultaneous EEG/fMRI recordings and relative grey matter volume (rGMV) reductions in 10 patients with MTLE. HC occurred beyond the seizure onset zone in the hippocampus, in the ipsilateral insular/operculum, temporo-polar and lateral neocortex, cerebellum, along the central sulcus and bilaterally in the cingulate gyrus. rGMV reductions were detected in the middle temporal gyrus, inferior temporal gyrus and uncus to the hippocampus, the insula, the posterior cingulate and the anterior lobe of the cerebellum. Overlaps between HC and decreased rGMV were detected along the mesolimbic network ipsilateral to the seizure onset zone. We conclude that interictal epileptic activity in MTLE induces widespread metabolic changes in functional networks involved in MTLE seizure activity. These functional networks are spatially overlapping with areas that show a reduction in relative grey matter volumes.
