1/150. Traumatic L1-L2 dislocation without fracture in a 6-year-old girl. Incomplete neurologic deficit and total recovery.STUDY DESIGN: A report of a rare complete dislocation of the first lumbar vertebra without fracture in a 6-year-old girl. OBJECTIVES: To describe a rare traumatic lesion in children. SUMMARY OF BACKGROUND DATA: Although there has been a report of posterior dislocations of vertebra without fracture accompanied by anterior apophyseal splitting in young cadavers, all in the cervical region, to date, there has not been a reported clinical case of vertebral dislocation in the thoracolumbar region in a child. methods: A 6-year-old girl, while playing on a farm, had her hair caught in the wheel of a sugar beet harvesting machine. She was referred with incomplete paraplegia. Radiologic examination showed an L1-L2 dislocation with no fracture. She was treated surgically using a modified Luque frame with sublaminar wires. RESULTS: Six months after injury, the patient had no neurologic deficit and was living an entirely normal life. Radiographs showed a perfect alignment of the thoracolumbar spine. At the 26-month follow-up, no radiologic abnormalities were observed, other than minimal end-plate sclerosis. Magnetic resonance images obtained after the removal of the implants showed no structural abnormalities in the vertebral column except disc narrowing at all instrumented levels, secondary to posterior fusion. CONCLUSION: To date, this is the first case of dislocation of the thoracolumbar spine in children. It is further notable because the neurologic deficit was incomplete, although there were striking radiologic abnormalities.- - - - - - - - - - ranking = 1keywords = plate (Clic here for more details about this article) |
2/150. Correction of knee deformity in patients with ellis-van creveld syndrome.Six knees in three patients with ellis-van creveld syndrome were treated with lateral soft tissue release and corrective osteotomy of the tibia at 10 years of age on average. The main feature was valgus deformity with lateral dislocation of the patella. All patellae were reduced. The valgus deformity improved from 35 degrees (range, 48 degrees-20 degrees) to 17 degrees (range, 35 degrees-5 degrees) of the femorotibial angle (FTA) on average, although the FTA in five of six knees was < 5 degrees after surgery. There was one recurrent case and one transient peroneal nerve palsy. The reason for undercorrection was a depression of the lateral tibial plateau. The deformity of the articular surface is the most important problem in correcting the valgus deformity of the knee in this syndrome.- - - - - - - - - - ranking = 1keywords = plate (Clic here for more details about this article) |
3/150. Atraumatic palmar midcarpal dislocation in a skeletally immature adolescent with hemiatrophy.We report a late presentation of a palmar midcarpal dislocation in an adolescent female with open growth plates who had no history of antecedent wrist injury. Midcarpal arthrodesis improved function and eliminated progressive pain.- - - - - - - - - - ranking = 1keywords = plate (Clic here for more details about this article) |
4/150. Irreducible palmar metacarpophalangeal joint dislocation due to junctura tendinum interposition: a case report and review of the literature.Three different anatomic structures have been reported to prevent reduction of a palmar dislocation of metacarpophalangeal joint: dorsal capsule, palmar plate, and a ruptured collateral ligament. In our case, extensor digitorum communis of the fifth finger and extensor digiti minimi subluxated on the ulnar side of the fifth metacarpal neck. Extensor digitorum communis of the fourth finger remained in its anatomic location. The junctura tendinum connecting the fourth and fifth extensor digitorum communis tendons slipped distal and then palmar to the metacarpal head, where it was trapped between the metacarpal neck and the base of the proximal phalanx. It was easily pulled out and the joint promptly reduced. Residual subluxation persisted due to rupture of the radial collateral ligament and the dorsal capsule. Repair restored joint reduction and stability. (J hand Surg 2000; 25A:166-172.- - - - - - - - - - ranking = 1keywords = plate (Clic here for more details about this article) |
5/150. Atlantoaxial dislocation associated with stenosis of canal at atlas.Three rare cases of stenosis of spinal canal at the level of atlas associated with atlantoaxial dislocation are presented. An atlantoaxial lateral mass fixation with plate and screws after posterior midline bony decompression was successfully performed in these cases.- - - - - - - - - - ranking = 1keywords = plate (Clic here for more details about this article) |
6/150. Failed closed reduction of a bifocal mandibular fracture because of dislocation of the mandibular ramus behind the styloid: case report.We present an unusual dislocation of the mandibular ramus after a low condylar fracture associated with a fracture of the opposite body of mandible. As closed reduction failed, both fracture sites were exposed. The mandibular ramus was dislocated behind the styloid process, which was not shown on the preoperative radiographs. The intermediate fragment was freed and the fractures treated by miniplate osteosynthesis. The patient made an uneventful recovery with no residual deformity.- - - - - - - - - - ranking = 1keywords = plate (Clic here for more details about this article) |
7/150. volar plate arthroplasty of the thumb interphalangeal joint.The fibrocartilaginous volar plate of the thumb interphalangeal joint is anatomically quite similar to the volar plate of the digital proximal interphalangeal joint. Due to this similarity, Eaton's technique of volar plate arthroplasty may also be utilized in fracture-dislocations of the thumb interphalangeal joint.- - - - - - - - - - ranking = 7keywords = plate (Clic here for more details about this article) |
8/150. Irreducible dorsal dislocation of the interphalangeal joint of the thumb due to the palmar plate. A case report.Dorsal dislocation of the thumb interphalangeal joint is rare. Only very few cases of irreducible dislocation has been reported at this joint. The authors report a case of compound irreducible dislocation due to the palmar plate interposition. The sesamoid, the flexor pollicis longus have been reported to block reduction of the dorsal dislocation of the thumb interphalangeal joint doctors on casualities should not insist if reduction is not easily obtained, the patient should then be guide towards a surgical team for surgical treatment.- - - - - - - - - - ranking = 5keywords = plate (Clic here for more details about this article) |
9/150. Isolated dislocation of the second metacarpal at both ends.A dislocation of the second metacarpal at both ends is reported herein for the first time. Six weeks after injuring her right hand in a fall while climbing stairs, a 34-year-old woman visited our clinic with pain, swelling, and deformity of her hand. The radiographs showed a volar dislocation of the head and a dorsal dislocation of the base of the second metacarpal. The probable mechanism of injury was the hyperextension at the metacarpophalangeal joint; this force dislocated the metacarpal head toward the volar plate. Force then further continued along the second metacarpal shaft in the hyperflexed wrist, thus dislocating the base dorsally. We performed an open reduction and K-wire fixation of the second metacarpophalangeal joint and an arthrodesis of the second carpometacarpal joint. At the six-month follow-up, the patient had restricted flexion (0 to 50 degrees) at the second metacarpophalangeal joint, but full range of motion at the interphalangeal joints. The grip strength on the right side was 70% of that measured in the uninvolved hand.

10/150. Dislocation of the incus into the external auditory canal after mountain-biking accident.We report a rare case of incus dislocation to the external auditory canal after a mountain-biking accident. otoscopy showed ossicular protrusion in the upper part of the left external auditory canal. CT indicated the disappearance of the incus, and an incus-like bone was found in the left external auditory canal. There was another bony and board-like structure in the attic. During the surgery, a square-shaped bony plate (1 x 1 cm) was found in the attic. It was determined that the bony plate had fallen from the tegmen of the attic. The fracture line in the posterosuperior auditory canal extending to the fossa incudis was identified. According to these findings, it was considered that the incus was pushed into the external auditory canal by the impact of skull injury through the fractured posterosuperior auditory canal, which opened widely enough for incus dislocation.- - - - - - - - - - ranking = 2keywords = plate (Clic here for more details about this article) |
