Pheochromocytoma is one of surgically curable hypertensive syndromes. The tumor is bilateral or extra-adrenal in 5% of cases in adults and in an even greater percentage in children and is most often familial. Herein we report two cases of pheochromocytoma, of which one is bilateral pheochromocytoma in a 20-year-old female and the other is left sided in a 27-year-old female.

With the increasing use of pedicular system to fix the spine, many complications are being reported. Recently many systems are available to fix the spine. However, each system has own advantages and disadvantages. The causes of metallic failure of Modular Segmental Spinal (MOSS) instrumentation on 42 consecutive patients undergone in Kang-Nam St. Mary's hospital since 1989 were reviewed. The specific aim of this investigation was to assess causes of metallic failure and loosening of this system on various spinal disorders. Of these, 8 cases had metallic failure and loosening. Breakage of screw and rod developed in 6 cases and dislodgement of rod from screw in 2 cases. In case of degenerative spondylolisthesis (unstable phase) with stenosis, however, the complications were closely correlated to expansile decompressive laminectomy to widen the narrowed spinal canal and the instrumental distraction to gain normal intervertebral disc space at the operation. Bony union and back pain were not correlated to metallic failure and loosening. Therefore, the main causes of metallic failure and loosening were (1) preoperative instability undergone expansile decompressive laminectomy including total bilateral facetectomy that aggravated preoperative instability, and (2) forceful instrumental dis traction. In cases needed these requirements, combined anterior interbody fusion or posterior interbody fusion should be added, heavier rods and screws larger than 3.5mm, 4.0mm in diameter, respectively, should be used. In addition to postoperatively sufficient bed rest and immobilization using rigid braces should be recommended to reduce these complications.

Since 1985, 7 symmetrical thumb polydactylies were treated with Bilhaut-Cloquet operation (V-shaped wedge out). As for Wassel's classification, two cases were type I (duplicated distal phalanx but not epiphysis) and two type IV (duplicated proximal and distal phalanx), and three type II (duplicated distal phalanx and epiphysis). Preoperatively, thumb polydactylies must be symetric and cut articular surfaces be accurately approximated. As for Wassel's type IV polydactyly, preoperative angiogram was done for detection of any vascular anomalies and tried not to damage the anomalous digital arteries of thumb. There was no postoperative complications. All patients and their parents were much satisfied with the postoperative results, but somewhat limited thumb motions were remained. In type I (2 cases) the average IP joint range of motion was 39°, in type II (3 cases) the average IP joint range of motion was 22°, and in type IV (2 cases) the average range of motion of IP joint was 21° and MP joint was 26°.

Fracture of the vertebral end plate in the lumbar and sacral spine has been reported as a rare lesion. Especially it is very rare that fractures are found at two levels simultaneously. To our knowledge, there has been only one reported case of this type of fracture in Korea3). We report a case of fractures of the vertebral end plates at two levels in adolescent patient.

Congenital vertical talus is dufficult to correct and tends to recur. Reduction of the deformed talon-avicular joint is rarely possible by conservative means alone and consequently surgical reduction is usually necessary. The technique of Kumar, Cowell and Ramsey(TAL, capsular release, open reduction of navicular, and K-wire fixation) was combined with or without tendon transfer using Tibialis anterior(Grice operation) in 11 feet of seven children(bilateral in four) under the age of four(2 girls and 5 boys), and followed them for average 41 months. Three of them were combined with cerebral palsy, syringomyelia, and multiple joint stiffness with camptodactyly. In preoperative radiograms, all of their tali are so distorted plantarward and medially as to be almost vertical. The talus was in an equinus position also but to a lesser degrees. The forefoot was dorsiflexed at the midtarsal joint and the navicular lay on the dorsal aspect of the talar head. Seven feet are corrected normally after operation, but four feet were recurred and soft tissue releasing techniques combined with extraarticular subtalar arthrodesis or triple arthrodesis were planned after their skeletal maturity.
