Treatment of failed osteosynthesis of the femoral head fracture is rarely reported in the literature. Arthroplasty is the preferred treatment for the elderly; however, it may not be suitable for young and active patients.

Abstract The obstetrical dilemma hypothesis (ODH) proposes an evolutionary trade‐off between obstetric requirements and locomotor performance. However, whether external pelvic breadth measures influence walking energetics during human growth remains poorly understood.

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...

Treatments for femoroacetabular impingement [PDF]
The hip is a ball and socket joint in which the femoral head (the ball) articulates with the acetabulum (the socket). In a condition called femoroacetabular impingement (FAI) the hip has a shape abnormality and is no longer perfectly spherical. The hip

Abstract Composed of various minerals, the eggshell provides ideal conditions for embryonic development, and understanding its composition and structure is essential for clarifying its relationship with bone formation. This study characterized the structure and mineral profile of the Rhinoclemmys punctularia punctularia eggshell in relation to ...

Evaluation of fretting wear on the femoral stem surface [PDF]
Fretting wear on polished femoral stems has been well documented in clinical reports, but in vitro simulation to replicate this wear has seldom been attempted and only limited success has been achieved.

Association Between Hip Translation and Hip Rotation and Anatomy: A Pilot Quasi-static MRI Study
Background: There is little known about translation of the hip and the relationship with hip rotation and morphology in asymptomatic patients. Hypotheses: (1) Femoral head would exhibit significant translations in asymptomatic hips, (2) femoral head ...

Abstract The Australasian crocodylian fossil record is dominated by the extinct endemic clade Mekosuchinae, with known members spanning the Eocene‐to‐Holocene. This diverse clade exhibited high morphological disparity, from early members superficially similar to Crocodylus, to more terrestrial forms later in the clade's evolutionary history.

Purpose To evaluate the comparative effectiveness of intra‐articular platelet‐rich plasma (PRP), stromal vascular fraction (SVF), bone marrow aspirate concentrate (BMAC), umbilical cord‐derived mesenchymal stem cell (UC‐MSC), and hyaluronic acid (HA) for pain relief and functional improvement in patients with knee osteoarthritis through network meta ...
