Objective: The aim of this study was to evaluate the safe zone for performing blind sternal procedures based on computed tomography (CT) evaluation of congenital midline sternal foramina using multidetector computed tomography (MDCT).
Materials And Methods: This retrospective study was carried out on 1,180 patients who underwent MDCT of the thorax from March 2015 to February 2016. The MDCT images were evaluated in axial and reformatted planes. Morphometry and prevalence of midline congenital sternal foramina (SF) and manubrio-foraminal distance (MFD) were evaluated. The safe zone was defined for a blinded intervention, based on palpable anatomical landmarks. Data were presented in terms of percentage, mean ± standard deviation and calculations were carried out using Microsoft Excel.
Results: The prevalence of SF in our study sample was 11.6 %. The majority of SF were located in a typical position in the lower sternal body at the level of fifth costo-chondral junction (CCJ) in 108 patients (78.8 %). The structure directly beneath the SF was mediastinal fat in 73 patients (53.3 %), followed by anterior pericardium in 44 patients (32.1 %) and lung parenchyma in 20 patients (14.6 %). The mean MFD in our study population was 11.90 ± 1.31 cm.
Conclusions: Sternal interventions should be avoided at the level of fourth to sixth CCJ, which is considered the danger zone. An intervention at the fourth to sixth CCJ may lead to disastrous consequences in patients who have SF.

Objective: A simple and minimally invasive combined procedure, including transconjunctival orbital fat removal and transcutaneous resected orbital fat injection, was performed based on the anatomical characteristics of the lower eyelids in our young Chinese patients. Our study aimed to investigate the efficacy and safety of this procedure in our study population.
Methods: In our retrospective study, a total of 183 consecutive patients underwent a combination of traditional transconjunctival blepharoplasty and nanofat grafting between February 2020 and June 2024.

Background: The ideal anteversion at which the acetabular and femoral components for a total hip arthroplasty (THA) should be implanted is still a subject of debate. One alignment philosophy being explored is restoration of individual constitutional femoral and acetabular anteversion. This study aimed to measure combined anteversion in a healthy hip population and understand the expected phenotypes and ranges for constitutional hip alignment.

Pillar stability has garnered significant attention owing to the effects of pillars on coal resource recovery rate, coal pillar stability, and coal bump risk. This study examined the roadway stability control principles of conventional and yield coal pillars. The conventional coal pillars were designed as load-bearing structures with a high load-bearing capacity to carry most of the abutment load, while yield coal pillars were designed as buffer structures for transferring rapidly increasing abutment loads to adjacent solid coal ribs by progressive deformation.

Background: Use of jumbo femoral heads (≥ 40 mm) in total hip arthroplasty (THA) decreases postoperative dislocation, however, may leave patients more susceptible to groin pain. Limited data exist for the effect of jumbo femoral heads and acetabular cup position on modern patient-reported outcome measures (PROMs). This study evaluated the effect of jumbo femoral heads and acetabular cup position on PROMs after primary THA.

Background: Endoscopic thoracic sympathectomy is a well-known and effective treatment for palmar and axillary primary hyperhidrosis (PHH). Its most frequent drawback and the main complaint among patients who underwent surgery is the appearance of compensatory sweating (CS). To date, no long-term studies using internationally standardized tools have assessed the efficacy and impact of this surgery on patients.
