Abnormalities of the posterior arch, including congenitally absent cervical pedicle and cervical spondylolysis, are rare entities that are usually found incidentally on neck radiographs. It is important to recognize these characteristic radiological features because their radiographic appearance may cause them to be confused with more serious entities such as fractures, locked facets, and tumor-induced bony erosions. Also, it is important to distinguish these abnormalities from similar pathologies to prevent the use of inappropriate treatment. We report the relevant clinical and radiological findings seen in three cases of posterior arch defect after trauma with review of pertinent literature.

There are numerous theories of pathophysiology in intracranial aneurysm, but currently accepted hypothesis was congenital defect of medial layer of vascular wall and the major developing factor was hemodynamics. Almost physicians were belived that treatment of intracranial aneurysm was completely through clipping of aneurysmal neck. But many reports were emphasized newly deloped intracranial(De Novo) aneurysm after clipping of initially identified intracranial aneurysm. The authors have same experienced of 2 cases intracranial "Do Novo" aneurysms. We are stress there were never completed treatment of aneurysm that clipping of initially identified intracranial aneurysm and should be attention to "De Novo" aneurysm.

PURPOSE: Three-dimensional (3D) effects of the single plane osteotomies of the proximal femur are compared and analyzed by the trigonometric method. MATERIALS AND METHODS: The shape of proximal femur was simplified as a bent line. The bent line is the continuation of the three points-the center of the femoral head, the center of femoral neck at the base, and the center of the femoral shaft. Then rotated the proximal femur at the junction of the neck and shaft with the each rotation axis of X, Y, Z, defined the frontal plane as a XY plane, sagittal plane as a YZ plane, and transverse plane as a XZ plane. RESULTS: The varus osteotomy of the proximal femur in the frontal plane with the rotation axis 'Z' that meant the increase of the X coordinate and the decrease of Y coordinate with constant Z coordinate (Deltax>Deltay, Deltaz=0) resulted in decreased anteversion in the transverse plane and increased flexion in the sagittal plane. The derotation osteotomy (Deltax>Deltaz, Deltay=0) resulted in varus in the frontal plane and extension in the sagittal plane. The flexion osteotomy (Deltaz>Deltay, Deltax=0) resulted in increased anteversion in the transverse plane and varus in the frontal plane. CONCLUSION: Single plane osteotomy for the proximal femur results in the angular correction in all three planes and may have the similar 3D effect of the certain double or triple osteotomy. So single plane osteotomy could be enough to correct some complex deformities.

Congenital coxa vara is a rare congenital deformity seen in infancy and childhood and usually not discovered until walking is begun and characterized by a progressive decrease in the angle between the femoral neck and shaft and consequently by a progressive shortening of the limb and also by the presence of a defect in the medial part of the neck We have experienced a case of it treated with valgns osteotomy and the case review is presented.

The femoral neck fracture having concomitant fracture of the femoral shaft occurs predaminantly in young man and have known to associate the serious complications. One of such factures is sometimes overlooked and is possibly due to a more obvious nature of the shaft fracture than that of the ipsilateral neck. Six cases of this type of combined fractures in ipsilateral femur are reported with the review of 1 iteratures. In six cases of the femoral neck fractures, three which were unrecognized at initial examiaation in early phase, resulting in serious residue as much as deformity and avascular necrosis of the femoral head, and other three were recognized in early at initial examination healed in good anatomic position and in due time. Through this observation it is stressed that early discovery and adaquate treatment of the fracture is the only solution to minimize the sequelae.

Osteochondroma, also known as osteocartilaginous exostosis or simply exostosis, comprises about 8.5% of all primary bone tumors and about 36% of those that are benign. Osteochondromas affect mostly the long bones; only 3% of solitary osteochondromas originate in the spine, while a solitary lesion in the cervical spine is distinctly rare. We present a case of osteochondroma of the upper cervical spine, presenting as a posterior neck mass. Although rare, spinal osteochondromas should be considered in the differential diagnosis of neck masses, and surgical treatment should be undertaken to correct secondary pain, disability, neurologic deficits, or cosmetic deformities.

A total of 236 anterior cervical interbody fusion has been performed. In 76 cases mostly Cloward's original method has used. During these operations several technical modifications were made. With these technique 159 cases were operated and showed marked beneficial results. 1. For widening of the interspace, a halter traction was better than the vertebra spreader. 2. Extension of the cervical spine when drilling of the vertebral bodies prevented the post-operative flexion deformity of the neck. 3. The dowel size, 2mm. In diameter larger than the drill hole was used and the cortical end plate of the dowel was fixed st the anterior edges of the vertebral bodies. 4. It was safe to leave the posterior edges of the vertebral bodies when drilling. 5. If the dowel was too thin, 2 pieces of the graft were packed. 6. Post-operative pain on the dornor bone site and walking difficutly wer minimized when the dowel was obtained from the inner aspect of the ileum. when the dowel was obtained from the inner aspect of the ileum. Many technical fitfalls of this type of operation were analyzed and discussed the improved surgery.

Congenital absence of a cervical spine pedicle is a rare clinical entity, and it is usually found incidentally on radiological studies performed after trauma in patients with cervical pain. We report two cases of congenital absence of a cervical spine pedicle and present a review of the literature.

PURPOSE: A lot of surgical techniques were tried to correct extension lag of distal interphalangeal joint. Spiral oblique retinacular ligament reconstruction is the one of correction techniques. METHODS: From January 2004 to January 2005, a total of 13 extension lag of distal interphalangeal joint corrections were performed using spiral oblique retinacular ligament reconstruction for 11 patients. After dorsal incision exposing from base of distal phalanx to proximal phalanx, the new ligament(half of lateral band or graft tendon) lies distally at the dorsum of the distal phalanx and passes volarly and proximally along the side of the middle phalanx and anterior and obliquely across the front of the proximal interphalangeal joint to the opposite side of the digit at the proximal phalanx. RESULTS: 5 of 6 mallet finger deformities and 7 swan neck deformities were corrected, which were both extension lag of distal interphalangeal joint and hyperextension of proximal interphalangeal joint. CONCLUSION: As a result, spiral oblique retinacular ligament reconstruction is an effective and recommendable method for correction of mallet finger deformity and swan neck deformity.
