Background: Femur intertrochanteric fractures are performed commonly in a supine position with a traction table. There is a challenge in obtaining traction tables, especially in low- and middle-income countries. However, there is still a debate on which position should be preferred if the traction table cannot be obtained.

Article Synopsis
  • - This study investigates the distribution of three types of nerve endings in human thumb interphalangeal (IP) joint capsules, focusing on their roles in sensing pressure, kinesthetic sense, and proprioception.
  • - Researchers examined five cadaveric thumbs and found that Type I nerve endings are more prevalent in the distal parts of the IP joint, while no significant differences were noted for Type II and Type III endings across different regions.
  • - The findings suggest that the distribution of nerve endings in the thumb's IP joint differs from those in the proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints, highlighting the need for more research on thumb physiology.

Purpose: This study aimed to analyze the correlation between ganglion cell complex thickness (GCCT) and vision compared with the choroidal thickness (CT) and central retinal thickness (CRT) in relation to the outcomes of intravitreal aflibercept treatment for choroidal neovascular membranes secondary to age-related macular degeneration (AMD).

Methods: This was a prospective, observational study. Forty-three eyes of 38 patients with wet AMD received a monthly loading dose of 2 mg aflibercept by intravitreal injection (IVI) during the first 3 months and were then followed at regular monthly intervals for an average of 10 months by a pro re nata regimen.

Objectives: This study aimed to examine the alterations in magnetic resonance imaging (MRI) characteristics of bioabsorbable magnesium (Mg) screws over time in a single center study in humans.

Methods: Seventeen patients who underwent medial malleolar (MM) fracture or osteotomy fixation using bioabsorbable Mg screws and had at least one postoperative MRI were included in this retrospective study. Six of them had more than one MRI in the postoperative period and were subject of the artifact reduction measurements.

Article Synopsis
  • This study investigates the safety and effectiveness of bioabsorbable magnesium screws for fixing tibial tubercle osteotomies (TTO), aiming to reduce the need for secondary surgeries related to hardware removal.
  • The research involved 10 patients with patellar instability, who underwent TTO with the magnesium screws, and showed successful osteotomy union without complications over an average follow-up of 11.5 months.
  • Results indicated a significant improvement in knee function scores, suggesting that bioabsorbable screws are a viable and beneficial option for TTO fixation compared to traditional metallic screws.

Purpose: This study aimed to investigate the morphological variations in the cross-sectional anatomy of the meniscus between similar-sized matched menisci.

Materials And Methods: Knee MRI of 329 patients with intact menisci were retrospectively reviewed, and the meniscal length (ML), meniscal width (MW), and cross-sectional dimensions (meniscal height and width) of the anterior, posterior horns, and the corpus were measured. Patients with similar-sized menisci who had less than 1 mm difference in ML and MW were matched.

Background: The purpose of this prospective case-control study is to investigate the relationship between quadriceps fat pad syndrome (QFPS) and patellofemoral morphology.

Materials And Methods: Twenty-two patients with QFPS and 22 age- and gender-matched healthy volunteers were included. The diagnosis of QFPS was supported both clinically and radiologically.

The anterior tibial artery (ATA) is the most critical anatomical structure at risk at the distal border of the posterolateral approach to the tibial plateau. This study aimed to use available lower extremity digital subtraction angiography (DSA) images to determine the distal safe limit of this approach by measuring the distance from the tibial joint line to the ATA where it pierces the interosseous membrane. Tibial plateau mediolateral width (TP-ML-W) and the perpendicular distances from the ATA to the tibial joint line and fibular head were measured on DSA images in 219 lower extremities.

Article Synopsis
  • The study aimed to identify the anatomical factors and meniscal shapes that contribute to noncontact anterior cruciate ligament (ACL) ruptures by comparing 63 patients with ACL injuries to 63 matched healthy individuals.
  • Data collected through knee MRI included various measurements like meniscal heights and widths, tibial slope, and notch width, analyzed for associations with ACL ruptures.
  • Findings revealed that certain anatomical risk factors, like decreased medial meniscus posterior horn height and increased lateral tibial slope, significantly correlate with increased risk of ACL rupture, highlighting the importance of meniscal morphology in such injuries.

Background: It is still unknown whether bioabsorbable magnesium (Mg) screws provide an advantage over titanium screws in the treatment of medial malleolar (MM) fractures. The purpose of this retrospective study is to compare the clinical and radiological outcomes of MM fractures fixed with either bioabsorbable Mg screws or conventional titanium screws.

Materials And Methods: A cohort of 48 patients with MM fractures who underwent compression screw fixation was retrospectively reviewed.

Purpose: This retrospective study aimed to compare the clinical and radiological outcomes of patients who underwent biplane chevron medial malleolar osteotomy (MMO) for osteochondral lesions of the talus (OLT), fixed with either magnesium (Mg) or titanium (Ti) screws.

Methods: A total of 22 patients (12 male and 10 female) with a mean age of 40.6 ± 12.

Objective: The purpose of this retrospective study was to compare the clinical and radiological results of magnesium versus titanium screw fixation for modified distal chevron osteotomy in hallux valgus (HV).

Materials And Methods: A total of 31 patients who underwent modified distal chevron osteotomy for HV deformity between 2014 and 2017 were reviewed retrospectively. Headless magnesium (Mg) compression screw fixation was applied in 16 patients (17 feet) and headless titanium (Ti) compression screw in 15 patients (17 feet).

Anterior talofibular ligament (ATFL) injuries can occur in three different distinct patterns; rupture of the ligament as a pure soft tissue injury, an avulsion fracture at the ATFL's attachment to either the fibula or the talus. Although fibular avulsion fractures are common, avulsion fracture of ATFL from talus is extremely rare with a single previously reported case in the current literature. A 34-year-old female with ATFL talar avulsion fracture associated with medial malleolar fracture was presented to the emergency department.

Aim: The purpose of this study was to investigate the role of anatomic variations in distal radius radiographic indices in patients with or without scaphoid fractures.

Materials And Methods: Radial inclination (RI), volar tilt (VT), radial height (RH) and ulnar variance (UV) were measured on wrist radiographs of 320 patients with (Group I, n = 167) or without (Group II, n = 153) scaphoid fracture, fall on outstretched hand (FOOSH). Receiver operating characteristics (ROC) curve analysis was used to assess the diagnostic performance for each variable.

Magnesium (Mg) bioabsorbable screws are new biomaterials used in fracture fixation. In the current literature, there is only one case report on the use of magnesium bio-absorbable screws in ankle fractures. Within the present study, a 19-year-old female who sustained an isolated lateral malleolar fracture was treated with open reduction and intramedullary Mg screw fixation and then followed up for two years.

Lipomas are benign tumors that rarely settle in the hand. They usually present with mass, pain, and nerve compression symptoms. Although isolated median or ulnar nerve compression neuropathy secondary to a lipoma of the hand has been widely reported, simultaneous median and ulnar nerve compression neuropathy are exceedingly rare and there are only three reported cases in the current literature to date.
