Traumatic boutonniere deformity of the thumb is rare in non-rheumatoid patients. Non-rheumatoid patient develops a boutonniere deformity of the thumb following a closed injury to the dorsoradial aspect of the metacarpophalangeal joint. The patient had an extensor lag of the metacarpophalangeal joint and paradoxical hyperextension of the interphalangeal joint. The patient required surgical treatment which included advancement and reattachment of the extensor pollicis brevis insertion and imbrication of the dorsoradial capsule to restore the anatomical alignment of the extensor pollicis longus. Conservative care of the metacarpophalangeal joint may be effective, but once a boutonniere deformity is developed, surgical treatment is necessary.

Traumatic dislocation of the metacarphophalangeal joint is a rare injury. Complex dislocation often require surgical procedure due to its anatomical characteristics. We report one case of surgically treated traumatic dislocation of the 5th metacarpophalangeal joint that was successfully reduced by volar open reduction without splitting the volar plate.

Dislocation of index metacarpophalangeal joint is complex and usually cannot be reduced by closed method. It is a relatively rare injury and there are no widely published studies on its management. We have experienced a case combined with osteochondral fracture of the dorsoulnar aspect of metacarpal head and reduced it using extensor tendon splitting simplified technique with good results. This technique is seemed te be simpler and safer than volar approach described by Kaplan.

PURPOSE: We analyzed the results of treatment of dislocation of the extensor tendons over the metacarpophalangeal joints. MATERIALS AND METHODS: Thirteen patients who had received treatment for dislocation of the extensor tendons over the metacarpophalangeal joint were reviewed. Ten patients had traumatic dislocations, two had spontaneous dislocations, and one had congenital dislocation. The long finger was most frequently affected. The other fingers were affected almost equally. Displacement of the extensor tendon always occurred in the ulnar direction in the long and ring fingers. The index and little fingers exhibited different patterns of dislocation. RESULTS: Nonsurgical treatment was undertaken in two cases. Surgery was performed in 11 cases. No recurrent dislocations were reported in any of the patients. Conculsions: Based on our experience, patients seen within 2 weeks of injury initially should be treated with splinting of the involved metacarpophalangeal joint. Chronic dislocations should be treated with a primary repair of the defect in the sagittal band. When the sagittal band is absent or deficient, the tendon must be stabilized using a loop procedure with a tendon slip.

PURPOSE: To describe the surgical treatment of the complex dorsal metacarpophalangeal dislocations and its results, emphasizing on the modified volar approach with A1 pulley release. MATERIALS AND METHODS: We experienced 6 cases of dorsal dislocation of the metacarpophalangeal joint. We performed open reduction with the modified volar approach described by Eaton and Dray. Postoperatively posteroanterior and lateral radiographs of the index finger metacarpophalangeal joint and metacarpophalangeal joint range of motion was followed. RESULTS: One case with a large osteochondral fracture was operated with volar and doral approach both. Overall end results were good without any significant restriction of motion and stability of the fingers. CONCLUSION: Modified volar approach with A1 pulley release is an excellent method for complex dorsal metacarpophalangeal dislocations without osteochondral fracture.

Acute calcific tendinitis in the hand is a very rare disease. We experienced two cases of acute calcific tendinitis of the abductor pollicis brevis in the hand. Both of the patients experienced pain, edema and erythema on radial side of metacarpophalangeal joint of thumb. We successfully treated the condition with aspiration and steroid injection under the ultrasonographic examination and subsequently, applied the casts. An improvement of the symptoms was observed with good results. In the present work, we report these cases with appropriate review of literatures.

To investigate the relationship of skeletal maturity among the normal occlusion group and each malocclusion groups, the author used hand and wrist X-ray of 133 Korean 13 year old boys (normal occlusion 30, Class I malocclusion 35, Class II malocclusion 35 and Class III malocclusion 33) and assessed their skeletal maturity. In this study, fourteen skeletal maturity stages were selected from; Radius, Hamate, Pisiform, Ulnar sesamoid of the metacarpophalangeal joint of the first thumb, proximal phalanges of the first, second and third finger, middle and distal phalanx of the third finger. The difference of skeletal maturity of each malocclusion groups in relative to normal occlusion group and that of each malocclusion groups were analyzed. The findings of this study can be summerized as follows: 1. Average skeletal maturity stage of each groups were MP3cap stage in normal occlusion group, H-2 stage in Class I malocclusion group, midstage between S and H-2 stage in Class II malocclusion group, MP3cap stage in Class III malocclusion group. 2. There was no significant difference in skeletal maturity of Class J malocclusion and Class III malocclusion groups in relative to normal occlusion group. 3. There was significant retardation of skeletal maturity in Class II malocclusion group in relative to normal occlusion group. 4. There was no significant difference in skeletal maturity between Class I and Class II malocclusion groups. 5. There was no significant difference in skeletal maturity between Class I and Class III malocclusion groups. 6. There was significant retardation of skeletal maturity in Class II malocclusion group in relative to Class III malocclusion group.

The extension type locked metacarpophalangeal joint of the little finger is an extremely rare condition characterized by loss of flexion with little or no loss of extension. The most common cause for locking is entrapment of a strap of the ruptured palmar plate. We treated a locked metacarpophalangeal joint of the little finger due to a hyperextension injury. The mechanism of locking was a torn part of the palmar ligament that forcefully rides across the prominence of the radial condyle of the metacarpal bone together with the accessory collateral ligament. These dislocated parts of the ligament formed a constricting bundle that prevented closed reduction. Locking was released successfully by an open reduction using the dorsal approach of the metacarpophalangeal joint without complication.

Dislocation of the metacarpophalangeal joint of the finger is rare except thumb. We experienced a case of volar dislocation of little finger and 2 cases of dorsal dislocation of index finger. The mechanism of injury seems to be direct trauma to the dorsum of hand with the metacarpophalangeal joint acutely flexed in volar dislocation and the dorsal dislocation is forced the metacarpophalangeal joint into hyperextension. In 1957, Kaplan advocated the triple incision, that is release of the volar fibrocartilageous plate, the natatory ligament, and the superficial transverse metacarpal ligament, exposing the operation field through a palmar approach. The recommended treatment for such very rare injury is open reduction through nalmar approach in dorsal dislocation, and dorsal approach in volar dislocation; the single most important element preventing reduction is interposition of the volar plate within the joint space in dorsal dislocation and the obstacles of volar dislocation are entraped dorsal capsule and partial ruptured extensor tendon. In dorsal dislocation, we advocated only half release of volar fibrocartilage for lessor trauma of soft tissue and reduction was made easily after release of 1/2 volar fibrocartilage. We report this rare and interesting cases with review of literature.
