Background: The complication rate after total elbow arthroplasties is higher than for other arthroplasties.
Purpose: The purpose of this study was to evaluate the complications and revision rate after 100 semi-constrained total elbow arthroplasties from various types of aetiologies performed in our university hospital.
Methods: One hundred linked semiconstrained total elbow arthroplasties were performed and were reviewed with 24-months minimum follow-up. Indications were rheumatoid arthritis (45), trauma (33), revisions (16) and others (6).
Results: At five years average follow-up (range, 2-11), the complication rate was 37 %. Most frequent complications were ulnar nerve involvement (9 %) and triceps insufficiency (7 %). Five implants were aseptically loosed. The infection rate was 4 % with loosening of the implant in two. Four fractures were observed, including three at the ulna and one at the humerus proximal or distal to the stem. The radial nerve was injured in two cases. Failure of the locking system of the prosthesis was noted in one case and a fracture of the ulnar component was found in another patient. A revision surgery was performed in 13 cases (13 %). At follow-up 94 prostheses were still in place and the survival rate was 98 % at five years and 86 % at ten years.
Conclusion: Total elbow arthroplasty remains a difficult procedure with sometimes a high rate of complications necessitating revision procedures. Selection of the patients, a rigorous surgical technique, and a systematic follow-up are prerequisite to limit this incidence.
Type Of Study/level Of Evidence: Therapeutic IV.

To date, there are no uniform guidelines for the treatment of obstetric plexus lesions in German-speaking countries. An end-to-end direct suture after resection of trunk neuroma is recommended for surgical treatment if tension-free coaptation is possible, whereas the use of autologous nerve grafts bridging the gap between the adaptation margins is advised by consensus if tension-free coaptation is impossible. The aim of the study was to investigate which reconstruction strategy may provide a better recovery of motor function for patients after obstetric brachial plexus lesion.

Background And Purpose: Children with myopathies often experience muscle weakness in their lower limbs. However, the upper limbs are also affected and, at the same time, play a key role in daily living activities as well as in transfers and assisted mobility using auxiliary devices. The objective was to assess the performance of the elbow flexor and extensor muscles through static and dynamic contractions in children with myopathies and in their typical peers.

Background: The purpose of this study was to assess the incidence of glenoid and humeral component malposition in failed primary shoulder arthroplasty requiring revision. We hypothesized that glenoid and humeral component malposition would be a prevalent feature in cases requiring revision arthroplasty for primary anatomic TSA, primary RSA, and primary hemiarthroplasty procedures.
Methods: A retrospective cross-sectional study was performed focusing on identifying the incidence of malpositioned components in shoulder arthroplasty in quantitative and qualitative reviews.

Introduction: Pediatric supracondylar humerus fractures are common and the most frequent pediatric fracture to require surgical intervention. After initial management, emergency department (ED) visits subsequent to this injury/surgery are not well characterized, but are of clinical interest.
Methods: Pediatric patients (age >1 y old and <13 y old) with supracondylar humerus fractures were identified from the 2010 to 2021 PearlDiver M157 administrative database.

Objectives: To evaluate the feasibility of recruitment, appointment adherence, intervention compliance, acceptance and comprehensibility, in addition to retention rate and data completeness. An ancillary aim was to describe within-group changes in the secondary outcome measures (patient-reported and performance-based).
Design: A single-centre, three-armed, randomised controlled feasibility trial with a parallel design, with follow-up after 3 and 6 months.
