 Fracture and dislocations of the carpometacarpal (CMC) joints except the thumb are relatively rare. Herein, we report the case of a delayed fracture-dislocation of fourth and fifth carpometacarpal joints.  The patient is a 41-year-old, right-handed male. To improve the complaints, such as decreased motion, reduced grip strength, and cosmetic appearance, surgical treatment surgically performed with resection of scar tissues and fixation using suture button at 11 weeks after injury. Movement began at 2 weeks after the surgery, which resulted in satisfactory appearance and good function of 92 and 101% of the motion of the unaffected side of the fifth CMC joint and grip strength, respectively.  Missed diagnosis can cause impairment of function including grip strength and range of motion. Nevertheless, a few previous studies reported that patients with delayed diagnosis did not need further treatment because of less functional loss and less improvement.  The surgical treatment using the implant allowed early motion from 2 weeks after surgery which resulted in good motion of the ulnar CMC joints as well as increased hand grip.
