Proximal row carpectomy, scaphoidectomy with midcarpal arthrodesis or midcarpal tenodesis: when and how to use.

Abstract

I report my personal experience over three decades in the treatment of carpal collapse due to scapholunate collapse and scaphoid nonunion. I have used the proximal carpal row resection performed through palmar approach, the scaphoidectomy and double-column midcarpal arthrodesis, and scaphoidectomy with midcarpal tenodesis. Diagnostic arthroscopy is essential for staging and surgical decision making regarding the type of treatment. The details of the surgical techniques, tips, results and possible complications are described for each method. The advantage of the proximal row carpectomy by palmar approach is the early permitted rehabilitation with better recovery of wrist motility in comparison with the traditional technique. The advantage of the double-column midcarpal arthrodesis lies in its ease of execution. The midcarpal tenodesis is an excellent intervention from the conceptual point of view even if over time there is a progressive carpal collapse even in absence of symptoms.
