Background: Lateral condyle fractures of the distal humerus are the second most common pediatric elbow fracture. A difference of 1 or 2 mm in fracture displacement measurement may change the operative or nonoperative management of a minimally displaced fracture. The goal of this study was to determine the interobserver and intraobserver agreement in the measurements of displacement of lateral condyle fractures of the humerus.
Methods: A retrospective radiographic review of 60 patients was performed by 3 reviewers. Fracture displacement was measured in millimeters on all radiographic projections and repeated by a single author 1 month later. Intraclass correlation coefficients (ICC) were calculated for intraobserver and interobserver agreement. We then calculated the percentage of measurements that differed by >1 or 2 mm. Analysis was performed on the entire cohort of displaced fractures and again separately for a cohort of minimally displaced fractures (defined as <5 mm).
Results: The combined ICC for intraobserver reliability across all radiographic projections was 0.96 (range, 0.952 to 0.977), but there was disagreement between a single reviewer's own measurements 17.3% of the time. Within the cohort of fractures displaced <5 mL, this intrarater disagreement (>2 mm) dropped to 4%. Interobserver reliability was also high with an ICC of 0.90 (range, 0.861 to 0.924). Within the minimally displaced cohort (<5 mm), the interrater disagreement was 6.6% when using a 2 mm cutoff and 22.2% when using a 1 mm cutoff.
Conclusions: Intraobserver and interobserver reliability are high when measuring lateral condyle fractures and the percent of clinical disagreement is low when measuring minimally displaced fractures for which treatment depends on measuring to the millimeter. The internal oblique projection is the most reliable view for measuring lateral condyle fracture displacement, whereas the external oblique view offers little in terms of reliability. This study may be used as a platform for further research, verifying that reliable measurements of lateral humeral condyle fracture displacement can be obtained within 1 to 2 mm from adequate plain films.
Level Of Evidence: Level III.

Comparison of costoclavicular and lateral sagittal infraclavicular approaches in ultrasound-guided brachial plexus block.

Objectives: Lateral sagittal infraclavicular approach is frequently used because it has less risk of complications and provides rapid and adequate regional anesthesia. Due to the fact that the brachial plexus is deeper in the infraclavicular region and the approach angle is sharper, it can be technically challenging. In this study, we aimed to compare the costoclavicular approach, which is a newly defined approach, with the lateral sagittal infraclavicular brachial plexus block.

Background: Hemifacial microsomia (HFM) presentation includes gross distorted ramus, malposition temporomandibular joint, small glenoid fossa, distorted condyle and notch, malformed orbit, cupping ear or absent external ear, and facial nerve palsy. HFM is the second most prevalent congenital deformity of the face, with little literature from the South African population. This retrospective study elucidated the demographic characteristics and clinical presentations of HFM patients in a select South African population and compared it to the literature.

Background: Vitamin E-diffused highly cross-linked polyethylene (HXLPE/Vit E) is a relatively advanced material used in total hip arthroplasty (THA) but whether it shows superiority is unclear.
Objective: This meta-analysis was performed to investigate the effect of HXLPE/Vit E liners in THA.
Methods: Medline/PubMed, Embase and Cochrane Library databases were searched to retrieve studies assessing the efficacy of HXLPE/Vit E liners in THA with the design of a randomized, controlled trial.

Background: Tunnel enlargement (TE) might jeopardize knee function and ligament stability after revision surgery of anterior cruciate ligament reconstruction. To date, only few studies concern TE following posterior cruciate ligament reconstruction (PCLR). This study aims to determine TE after isolated PCLR and its relationship with patient-reported outcomes.

Background: In medial mobile-bearing unicompartmental knee arthroplasty (MB-UKA), the position of the bearing does not correspond to the planned position which will increasing the risk of bearing dislocation. This study aimed to explore the relationship between the malposition of the femoral and tibial components and the phenomenon of bearing deviation using postoperative radiological measurements.
Methods: One hundred twenty patients who underwent mobile-bearing uni-compartmental knee arthroplasty (MB-UKA) at our hospital between January and August 2023 were enrolled in this retrospective study.
