Hosted by the ORS Scientific Communications Committee, the goal of the ORS Scientific Photo Competition is to use images to highlight musculoskeletal research. Winning images will be featured on the ORS website and on ORS Social Media outlets.

Select your favorite photos from the gallery below and submit your vote.  One vote per person, please!

The deadline to vote for your favorite is Monday, February 10!

ORS Photo #1

Canine tibia: trabecular and subchondral bone, calcified cartilage, tidemark, articular cartilage, and ACL (CrCL) insertion. 100micron plastic section, Toluidine blue surface stain, plane polarized light

ORS Photo #2

In situ hybridization for Fgf18 and Wnt7b within and around the deltoid tuberosity

ORS Photo #3

A micro computed tomography scan of a human radius

ORS Photo #4

Knee articular cartilage expressing type II collagen (red) and periostin (green). blue = nuclei

ORS Photo #5

Supraspinatus tendon entheses at different developmental stages (from left to right: Postnatal day 1 (P1), P7, P14, P28, P91), highlighted by Safranin O staining

ORS Photo #6

Giant cell reaction to polyurethane-urea elastomer

ORS Photo #7

Pentachrome staining reveals robust cellular response and ECM remodeling at the repair center of mouse Achilles tendon 14 days after transection and suture repair

ORS Photo #8

Image of intact murine spine showing vascularization of spinal chord

ORS Photo #9

Hydroxyapatite particle in bone matrix

ORS Photo #10

From left to right, this image shows HRpQCT data of the distal radius, which was subjected to compressive loading; strain distribution within the cortical shell during loading (from FE), 5th and 95th percentile elements; and locations of bone formation/resorption after 12 months of loading

ORS Photo #11

The picture shows Julius Wolff, who postulated Wolff’s law in 1892: The law of transformation of the bone, which describes the relationship between bone geometry and mechanical influences on bone

ORS Photo #12

A lady aged 44 presented with a dinner fork imbedded in her left wrist. During a “domestic” she hit the kitchen table with the fork with such a force that it bent back on itself and imbedded into her left wrist. Yet another dinner fork deformity usually seen with Colles’s fractures

ORS Photo #13

Skeletal muscle regeneration from human dermal fibroblast-derived fibromodulin reprogrammed cells in cardiotoxin injured gastrocnemius muscle of SCID mice, abundant skeletal muscle regeneration was confirmed by cells that stained positively for human MHC Class I (green) and human myosin (red), cell nuclei were stained with DAPI (blue)

ORS Photo #14

This photo presents a smiling chondrocyte

ORS Photo #15

CT 3d reconstruction of bony sequestrum arising from the base of the 2nd metacarpel

ORS Photo #16

Microstructure of decellularized cancellous bone extracellular matrix via scanning electron micrioscope and micro-CT imaging

ORS Photo #17

Histone-H2B super-resolution stochastic optical reconstruction microscope (STORM) image (left) and H2B density map (right) in a human tendon cell nucleus

ORS Photo #18

Severe simultaneous articular cartilage erosion (left) and subchondral bone plate sclerosis (right) in a human tibial plateau with advanced osteoarthritis illustrated by 3D reconstructed micro-CT images

ORS Photo #19

Growth of the mouse knee joint from E17.5 to P28 is seen here in the Col1/Col2/COl10 reporter mouse, in which expression of Col1, 2, and10 corresponds to YFP, CFP, and RFP expression, respectively

ORS Photo #20

Different presets of 3D reconstructed image of CT angiogram showing complex intra-articular proximal tibia fracture

ORS Photo #21

Mouse knee joint fluorescent image, showing Prg4Cre driving GFP reporter labeled articular cartilage in green, nuclei in blue

ORS Photo #22

3D reconstruction of mouse cartilage after DMM surgery. Red: type 2 collagen; Green: active-beta catenin; Blue: Dapi

ORS Photo #23

We found that loss of a G protein-coupled receptor in cartilaginous tissues leads to osteoarthritis-like cartilage degeneration in mouse knee joint

ORS Photo #24

At embryonic day 13, the notochord (green) spans 5 nascent intervertebral discs, highlighted by Actin (red)

ORS Photo #25

Contrast Enhanced micro CT images of Tendon-to-Bone attachment revealed that, hidden within the well-known larger apparent attachment footprint area, is a smaller, much denser primary insertion site where tendon fibers insert directly into the bone surface
