– Traumatic: Fractures of the carpal bones (such as the scaphoid or radius) or ligament tears (such as scapholunate or lunotriquetral ligament tears) that can lead to accelerated wrist wear.
– Osteoarthritis: Wear and tear associated with aging is the most common form of wrist stiffness.
– Rheumatoid and inflammatory arthritis.
– Gouty arthritis.
– Septic arthritis.
Clinical examination will show:
– Tenderness around the joint
– Deformity or angulation
– Limited range of motion
Tests:
– X-ray of the involved joint will show various degrees of joint destruction
– Blood tests
Joint fusion or replacement can be considered depending on the affected joint and lifestyle. Several selective joint fusions can alleviate pain while preserving motion. Different types of partial wrist fusions include:
– Four corner fusion with resection of the scaphoid.
– STT fusion (between scaphoid, trapezium and trapezoid)
– Capito-lunate fusion (between capitate and lunate)
– Scaph-capitate fusion (between scaphoid and capitate)
– Radio-scapho-lunate fusion (between radius, scaphoid and lunate)
We will always favour motion-preserving procedures but in very advanced stages, only a formal wrist fusion will treat the pain.
Wrist arthroplasties include proximal row carpectomy, partial joint resections (such as distal scaphoid resection to treat STT arthritis). Arthroscopic procedures are evolving significantly and new implants are being developed to improve the possibilities of minimally invasive wrist surgery. Theses sophisticated surgical procedures require period of postoperative immobilization, to allow bones and joints to heal.
Possible complications include pain, bone non-union, stiffness, nerve or tendon injuries and the need for additional procedures, such as:
– Capitolunate fusion
– Four corner fusion
– Partial wrist fusion
– Total wrist fusion
