Isolated dislocation of all five carpometacarpal joints is extremely rare, only eleven cases had been reported since 1873. In Korea, we have not seen it probably. We experienced one case of isolated dislocation of all five carpometacarpal joints with a good result in I year after closed reduction and internal fixation.

PURPOSE: To evaluate the classification and treatment results about the injury of carpometacarpal (CMC) joint with the fracture of hamate. MATERIALS AND METHODS: The authors categorized into 3 types (I, II, III) according to the location of injured CMC joint and type II was subdivided into 2 type (a, b) according to the size of coronal fragment of hamate fracture-type I: fracture-dislocation of 5th CMC joint with small-sized fragment or avulsion fracture of hamate, type IIa: fracture-dislocation of 4th and 5th CMC joint with small-sized fragment or avulsion fracture of hamate, type IIb: fracture-dislocation of 4th and 5th CMC joint with coronal fracture of hamate body presenting an oblique or coronal splitting fracture, and type III: type II injury associated with injury of 3rd CMC joint or coronal plane fracture of capitate. All cases were carried out the operative treatment. And radiologic results and clinical results were evaluated. RESULTS: Type I were 2 cases, type IIa 4, type IIb 5, and type III 3. Twelve of 14 cases were excellent or good results, 1 case (type III) was fair, and 1 case (type IIa) was poor. All cases obtained anatomic reduction of CMC joint. But, the posttraumatic arthritis was observed in 1 case (poor) and the displacement of non-fixed hamate fragment was observed in 1 case (fair). CONCLUSION: We think that it may get more favorable outcomes by the fixation of the relative large fragment of hamate with anatomical reduction of CMC joint.

Eaton and Littler's ligament reconstruction is used to treat carpometacarpal instability of the thumb using the flexor carpi radialis tendon. This procedure involves a reconstruction of the deep anterior oblique ligament in patients with post-traumatic prearthritic unstable joints. According to a recent paper, the dorsoradial ligament as well as the deep anterior oblique ligament plays an important role in stabilizing the trapeziometacarpal joint. We report three cases of post-traumatic instability in a prearthritic thumb that was treated with Eaton and Littler's reconstruction using the flexor carpi radialis tendon.

PURPOSE: There is little information about the treatment of carpometacarpal (CMC) fracture-dislocations. The purpose of this study was to investigate treatment methods and times between diagnosis and surgery in CMC fracture-dislocations. MATERIALS AND METHODS: In 18 cases treated by surgery, the 4, 5th CMC joints were found to be the most frequently involved in 13 cases. Comminution of the carpal or metacarpal bone was present in 8 cases. The time to surgery was within 3 days in 10 patients, within 5 days in 6, within 9 days in one patient and more than 4 weeks in one. All the injuries were managed by closed reduction and K-wire fixation except for one which was detected after 4 weeks since initial trauma. RESULTS: A painless full hand function was restored in 13 cases. Intermittent pain was present in 5 cases in which there was comminution in 4. However, clinically full hand function was restored in 4 cases except for one in whom the treatment was delayed. CONCLUSION: If the treatment of CMC fracture-dislocation is not delayed a successful result can be gained using the closed method even though comminution occurs.

Posttraumatic instability of the carpometacarpal joint of the thumb are rarely reported. Consequently little is known about clinical and radiologic diagnosis, natural progress or treatment method. We report three cases of chronic instability of the carpometacarpal joint of the thumb treated with Eaton and Littler's ligament reconstruction. Satisfactory thumb functions were restored without arthritic change or recurrent subluxation.

Pure dislocation of 1st carpometacarpal (CMC) joint is uncommon and may be missed initially. The neglected dislocation of 1st CMC joint can be reduced by open method and required capsular repair or ligament reconstruction for stability of 1st CMC joint. We experienced the patient with an old dislocation of 1st CMC joint which was recognized 9 months after the injury. Open reduction was impossible, therefore we treated by the trapezial excision and ligament reconstruction tendon interposition arthroplasty, resulting in painless functional joint.

The trapezoid metacarpal dislocation is a rare event. In the literature, it is found in case reports. This injury is caused by direct or indirect high energy trauma. In most cases, the dislocation is dorsal and is difficult to reproduce because the joint is not very mobile. Given the low incidence and little evidence supported in the literature regarding the management, this injury can be treated by open or closed reduction; however, it has been published that most authors use Kirschner wire fixation with good results. Here we present our experience in the management of a male patient with acute trapezoid metacarpal dislocation handled with a splint with good functional results at 6 weeks.

Ganglion cysts that arise from the palm and compress the median nerve are rarely reported. Previous studies have described ganglion cysts compressing the motor branch of the median nerve, but no reports have described sensory neuropathy of the common palmar digital nerve as a result of ganglion cysts. We present a case of sensory neuropathy similar to carpal tunnel syndrome caused by a ganglion cyst that originated from the second carpometacarpal joint.

Simultaneoulsy carpometacarpal fracture and dislocation is known to be uncommon past days. But Fisher1 reported that it is quite common injury of hand in 1984. Also high energy injury causes carpometacarpal joint fracture and dislocation, the result of treatment has wide spectrum of prognosis, so early diagnosis and treatment is essential. We reported 2 patients who had the fourth and fifth carpometacarpal fracture and dislocation.
