Total Hip Arthroplasty: Effect of Head Size, Offset Gap, Offset Angle, Trunnion Length and Fixation on Trunnionosis of Hip Implant
Sign Up to like & getrecommendations! Published in 2025 at "International Journal for Numerical Methods in Biomedical Engineering"
DOI: 10.1002/cnm.70106
Abstract: Trunnionosis can be defined as the wear of the femoral head–neck contact. This phenomenon is increasingly recognized as a major factor in hip arthroplasty failure. The selection of a highly compatible head has become crucial… read more here.

The role of femoral head size in metal-on-metal hip arthroplasty: analysis of a cohort of 3813 patients with long term follow-up

DOI: 10.1007/s00402-024-05567-0
Abstract: Metal-on-metal (MoM) large headed arthroplasties were suggested to decrease failure rates by means of reduced volumetric wear and enhanced implant stability. However, they caused high rates of revisions due to adverse reaction to metal debris,… read more here.

Sexual dimorphism in size and shape of the head in the sea snake Emydocephalus annulatus (Hydrophiinae, Elapidae)

DOI: 10.1038/s41598-021-99113-2
Abstract: In snakes, divergence in head size between the sexes has been interpreted as an adaptation to intersexual niche divergence. By overcoming gape-limitation, a larger head enables snakes of one sex to ingest larger prey items.… read more here.

Understanding the role of head size and neck length in micromotion generation at the taper junction in total hip arthroplasty

DOI: 10.1038/s41598-024-57017-x
Abstract: Modular hip implants allow intra-operative adjustments for patient-specific customization and targeted replacement of damaged elements without full implant extraction. However, challenges arise from relative micromotions between components, potentially leading to implant failure due to cytotoxic… read more here.

DOI: 10.1111/jzo.12520
Abstract: Sexual dimorphism in head size and shape has been documented in many animals and is often thought to be related to the consumption of different prey in males and females thus reducing competition between the… read more here.

Dark ventral colouration indicates head size in a semi‐colonial gecko
Sign Up to like & getrecommendations! Published in 2024 at "Journal of Zoology"
DOI: 10.1111/jzo.13237
Abstract: Several animals present ornamental colouration which acts as signals in sexual or other social contexts by indicating some trait of the bearer. This colouration is often present only in one sex and may be produced… read more here.

DOI: 10.1177/2309499016684298
Abstract: Purpose: To evaluate intraoperatively the effects of femoral offset and head size on stability of the hip joints in total hip arthroplasty (THA) via posterior approach. Methods: Thirty cementless THAs were included in this study.… read more here.

DOI: 10.17222/mit.2020.113
Abstract: Contemporary craniofacial surgery includes the preand post-operative optical 3D scanning of faces as a method for diagnosing and verifying the achieved results. The influence of head size in 3D scans must be excluded in order… read more here.

Ontogenetic progression of individual head size in the larvae of the beetle Trypoxylus dichotomus (Coleoptera: Scarabaeidae): catch-up growth within stages and per-stage growth rate changes across stages
Sign Up to like & getrecommendations! Published in 2023 at "PeerJ"
DOI: 10.7717/peerj.15451
Abstract: The ontogenetic progression of insect larval head size has received much attention due to its fundamental and practical importance. However, although previous studies have analyzed the population mean head size, such an approach may not… read more here.
