- Lesion of radial artery
- Lesion/Severing of FCR
- Lesion of the branches of the superficial branch of the radial nerve as well as the medial antebrachial cutaneous nerve
- Incomplete removal of the trapezium
- Fracturing of the bone during drilling
Management
- Primary microsurgical nerve or artery suture
- Careful exposure of the bone and its osteophytes. Control of the resection by palpation of the surgical area, if necessary, fluoroscopy control
- If possible, reconstruction of the FCR tendon and change of procedure (trapeziectomy alone, if necessary with fixation of the 1st metacarpal bone using K-wires to the 2nd and 3rd metacarpals)
- In case of fracturing, change of procedure with suspension by partial transfer of the APL (Abductor pollicis longus tendon)
