title: [Trapeziometacarpal denervation. Description of surgical technique and preliminary results from a prospective series of 14 cases].
abstract: BACKGROUND
  The main goal of first carpometacarpal arthritis surgical treatment is to relieve pain. The main disadvantages of the usual techniques (trapeziectomy, implant arthroplasty) are loss of strength or presence of a prosthetic device. It is difficult to propose such extensive surgery at an early stage of the disease. Selective denervation of the first carpometacarpal joint seems to be an interesting choice. We propose a new technique of denervation based on our previous anatomical investigations.
  
  
  METHODS
  Two incisions are needed to cut all the articular branches derive from the superficial branch of the radial nerve, the palmar cutaneous branch of the median nerve, the thenar branch of the median nerve and the lateral ante brachial cutaneous nerve.
  
  
  METHODS
  Fourteen patients were prospectively included in our study with a mean follow-up of 5 months.
  
  
  RESULTS
  Pain relief was very satisfying in 12 cases (mean decrease 84%). An increase in grip and key pinch strength was noted. Complications were uncommon, excepted temporary paresthésia in the radial nerve area.
  
  
  CONCLUSIONS
  This technique seems to be promising and a good indication for patients with no disabling deformity, but only long-term results will confirm the place of denervation in the treatment of first carpometacarpal arthritis.
