title: [Scaphoidectomy (instead of trapezectomy) in the treatment of rhizoarthrosis. Report of a case].
abstract: BACKGROUND
  Surgery site errors and technical errors in hand surgery are rare and not often published.
  
  
  METHODS
  A 46-year-old patient with rhizoarthrosis of the left hand was initially treated by mistake in another center by a scaphoidectomy instead of a trapezectomy. She was seen in consultation 6months later, still suffering from her rhizoarthrosis and with carpal instability, clinically symptomatic and radiologically confirmed. The instability of the wrist was treated by a hamatocapito-lunar arthrodesis and a trapeziometacarpal arthrodesis was performed to treat the rhizoarthrosis. The clinical and radiological results were acceptable.
  
  
  CONCLUSIONS
  Besides the paradigmatic error, this observation confirms that the excision of the scaphoid quickly leads to a destabilization of the wrist, the capitatum no longer maintaining its alignment under the lunatum, and leads to a limitation of the wrist mobility and a loss of strength. The hamato-capito-lunate arthrodesis described in 1997 can treat wrist instability and only the trapeziometacarpal arthrodesis can, in the absence of scaphoid, treat the problem of rhizoarthrosis.
  
  
  CONCLUSIONS
  The authors recommend to always carry out a radiography of the wrist during trapezectomy surgery when there is doubt about the identification of the trapezium.
