Ulnar wrist pain is very common and refers to pain on the pinkie side of the wrist. It can results from Fractures, athritis and other causes
Some causes of ulnar wrist pain include:
Wrist fractures
Arthritis of the joint(s) between bones
Ulnar impaction syndrome (when the ulna is longer than the radius, which can cause it to “bump into” the smaller wrist bones (Figure 2)
Inflammation or irritation of the tendons that bend and extend the wrist
Triangular Fibrocartilage Complex Injury (TFCC) (when the connection between the ulna bone and other structures in the wrist is torn by an injury or frayed over time)
Nerve injury or compression
Masses (tumors), most commonly ganglion cysts, which are benign
