skeleton

abnormal phalanx morphology ( J:125122 )

• the proximal and middle phalanges are short and fused and obviously shortened in digits 2 and 5

abnormal long bone epiphyseal plate morphology ( J:125122 )

• the growth plate of the distal femur and proximal tibia are abnormal

abnormal long bone epiphysis morphology ( J:125122 )

• the trabecular bone is poorly formed at the epiphysis of the knee joint

decreased length of long bones ( J:125122 )

• long bones in the hinblimb (tibia, fibula and femur) are shortened

decreased chondrocyte number ( J:125122 )

• chondrocyte number in degenerating elbow joints is reduced

abnormal articular cartilage morphology ( J:125122 )

• elbow joints exhibit early degenerative changes in the articular cartilage

• articular cartilage surface is fribrillated, cracking, and loses the superficial zone

fused joints ( J:125122 )

• the carpal/tarsal, proximal interpharlangeal, metacarpo-/metatarso-phalanges,and knee joints are fused

• however, the phalanx, distal interphalangeal, wrist and elbow joints are normal

limbs/digits/tail

abnormal phalanx morphology ( J:125122 )

• the proximal and middle phalanges are short and fused and obviously shortened in digits 2 and 5
