It is well known that intracranial pressure (ICP) and mean arterial pressure (MAP) are increased by laryngoscopy and endotracheal intubation during induction of general anesthesia, and it may be very dangerous in neurosurgical patients who had increased ICP. Therefore, this study was performed to know the range of ICP increase during induction of the conventional general anesthesia with intubation following thiopental and succinylchohne injections. Intracranial pressure and MAP were measured in 13 patients who underwent craniotomy. All the patients were monitored cerebral epidural ICP and intraarterial pressure preoperatively. The results were as follow: 1. Intracranial pressure was increased of 7.1±7.23 mmHg. 2. Arterial pressure was increased of 43.5±25.46 mmHg. 3. Cerebral perfusion pressure was increased of 33.3±27.53 mmHg. It is stressed that certain procedures are necessary to prevent from further increase of ICP due to induction of general anesthesia in patients with increased ICP.

A case of thumb-in-palm deformity due to burn scar contracture. Recently it is felt that the incidence of thumb-in-palm deformity due to old burn scar contracture is far less than that of other causes; for example carebral palsy, trauma, Co. poisning etc; This case is a 23 years old male soldier who had sustained burn on the left palm at his age of 4, and the left thumb has been gradually contracted, resulting to established thumb-in-palm deformity evantually. There is no active or passive motion in the metacarpho-phalangeal phalangeal joint and carpho-metacarpal joint of left thumb. The distal phalanx is moderately atrophied and its nail is deformed. On act 6th, 1975 he was operated on soft-tissue releasing with Z-plasty fasciotomy of palmar aponeurosis and myotomy of adductor pollicis and flexor pollicis brevis with split thickness skin graft. Postoperatively he could have full extension of the left thumb as well as active flexion of metacrpho-phalangeal and interphalangeal joint with slight adducted state. He is able to take opposition of left thumb at the present time postoperative four weeks.

Unstable Colles' fractures have an inherent capacity for loss of reduction or shortening, or both. The istability can be recognized by the presence of much comminution, severe dorsal angulation(20 degrees or more), or extensive intra-articular involvement. It is difficult to align the fracture fragments and to maintain the reduction. In twenty-nine patients with unstable Colles' fracture from Jan. 1982 to Mar. 1984, several invasive methods were used. The results were as follows: 1. Among 147 patients with Colles' fractures 29 patients(19.7%) had unstable fractures. 2. Colles' fracture was occurred more frequently in women(77%) and in 6th and 7th decades(56%). Unstable fractures showed no significant age and sex related propencity. 3. Mechanism of injury caused unstable Colles' fractures were fall on the outstretched hand(25 patients), traffic accident(3 patients) and crushing injury(1 patient). Open fractures were shown in 4 patients among the unstable fractures. 4. Most of the unstable fractures were comprised of type VII and VIII(49%) but type I and II fractures with marked comminution or displacement also showed instability. 5. Complications were such as, redisplacement of the fractures, temporary neuropathy of the median nerve, compartment syndrome, Sudeck's atrophy, and shoulder-hand syndrome. 6. Overall assessments showed excellent in 4 patients, good in 16 patients, fair in 7 patients and poor in 2 patients. 7. Overall results were mainly correlated with initial severity of the injury and anatomical restoration of the fractures.

The head patient with musculoskeletal trauma is a challenge to the orthopedic surgeon and its incidence is increasing markedly with the development of modern culture and a high velocity motor vehicle. So, for the purpose of studying the difference between lower extremity fracture concomitant with head injury and only lower extremity fractured patients, we studied the radiologic bone union time, serologic test and heterotopic ossification. For the control group we analysed each 10 patients of only femur and tibia fractures. The following clinical results were obtained by analysis of 46 patients of lower extremity fracture concomitant with head injury, experienced in the Department of Orthopedic Surgery, Yonsei University College of Medicine in past 5 years from Jan. 1980 to Dec. 1984. 1. The mean age was 24.5 yrs old (2~6 yrs old) and the prevalent age was 1st and 3rd decade, and the sex ratio between males and females was 2.8: l. 2. The most common mode of injury was auto-pedestrian injury (84.8%) and the other was falling down injury(15.2%) . 3. The common brain injuries were cetebral contusion with skull fracture (37.0%) and cerebral contusion only(34.8%) . Among 26 patients whos mental states were not alert, 23 patients recovered mental states completely. 4. Serum Calcium, Phosphate, and Alkaline Phosphatase level were no difference between the head injury with lower extremity fractured patients and only lower extremity fractured patients. 5. There were no evidence of early bony union in the patients with head injury. 6. The formation of callus were abundant in the patients of lower extremity fracture with head injury rather than the only lower extremity fractured patients. 7. The incidence of heterotopic ossification was 10.9% and all patients with heterotopic ossification were treated with physiotherapy and all patients recovered fully. 8. The incidence of complication was 17.3% and there was no fat embolic patients. In conclusion, there was no evidence of early bony union, but the callus formation was abundant in the patients of lower extremity fracture concomitant with head injury.

We performed twenty three cementless total hip arthroplasties(THA) on seventeen patients, all of whom were diagnosed with steroid-induced avascular necrosis of the hip (AVN). The average age of the patients was 41years, mean follow-up period was 41months (24-74months). The final average Harris hip score was 94 and overall results were excellent. On radiographic evaluation, 17 femoral components met the criteria for bone ingrowth(spot weld) but it was somewhat delayed. There was no evidence of loosening of the femoral and acetabular components. The results of this study suggest that long term steriod treatment does not prevent bone ingrowth. Cementless total hip arthroplasty appears to be a reasonable therapeutic option for steroid-induced avascular necrosis of the hip.

Massive hemorrhage into an intracranial neurinoma is a rare event. A 42-year old man noticed hearing loss, nystagmus, diplopia and paresthesia on the left side of the face. A computerized tomography scan demonstrated a large high density mass in the left cerebellopontine angle. The tumor was successfully removed and postoperative course was favorable. Such a case of acoustic neurinoma which revealed itself through intratumoral hemorrhage has not been previously reported in Korea.
