*: measurements of XROMM study animals retrieved from x-ray images.
Scapula length is measured as distance from angulus inferior to acromio-clavicular joint; spina scapulae length is measured along spina scapulae from vertebral border to glenoid cavity. Hand length is measured from wrist joint to distal interphalangeal joint. All values are reported in cm.
