Radiocarpal (RSL) fusion can treat isolated radiocarpal arthritis but may cause limited wrist motion and complications. It remains an option for specific patients if the midcarpal joint is healthy.

Area of Science:

  • Orthopedic Surgery
  • Hand and Wrist Surgery
  • Arthritis Treatment

Background:

  • Radiocarpal (RSL) fusion is a surgical option for isolated radiocarpal arthritis.
  • Wrist joint kinematics present challenges for independent midcarpal motion post-RSL fusion.

Purpose of the Study:

  • To evaluate the outcomes and limitations of RSL fusion for radiocarpal arthritis.
  • To discuss the suitability of RSL fusion in specific patient populations.

Main Methods:

  • Review of existing literature on RSL fusion outcomes.
  • Analysis of biomechanical considerations of wrist joint kinematics post-fusion.

Main Results:

  • Successful RSL arthrodesis is expected to result in limited wrist flexion and extension.

  • Complications include high rates of RSL nonunions, scaphoid fractures, and midcarpal joint deterioration.
  • RSL arthrodesis is a viable alternative to complete wrist fusion for select young patients with isolated radiocarpal arthritis and a healthy midcarpal joint.

    • Conclusions:

    • RSL fusion is a viable option for isolated radiocarpal arthritis, but its limitations must be considered.
    • Careful patient selection is crucial, particularly regarding the condition of the midcarpal joint.
    • Technical considerations like internal fixation and scaphoid excision may be employed during RSL arthrodesis.
