Bone marrow pressure is neither arterial pressure nor venous pressure of extremity, that is thought the precapillary pressure of bone. It is different between long bone and flat bone, and is also different in various site of the bone. Author measured bone marrow pressure of 84 normal femoral heads of Korean adults for basic data of early diagnosis of avascular necrosis of femoral head. The results are followings : 1. The baseline bone marrow pressure of Korean healthy adults is average 22.5 ±7.2mmHg. 2. The most significant change of bone marrow pressure in stress test is observed at 5 min. after injection of 5cc normal saline. 3. The increase of bone marrow pressure at 5 min. after stress test was average 7.4 ±4.4 mmHg. 4. Sex and age factors do not influence bone marrow pressure.

The absence of palmaris longus musle is common, about 10% in general population, but absence of another muscle(S) in forearm and/or hand is very rare. We experienced a case of conenital absence of flexor digitorum profundus in both hands. It was confirmed by surgical exploration. This anomaly seems to be extremely rare case in the English literature.

Authors measured the bone marrow pressure(B.M.P.) of 59 femoral heads in cases of either suspicious or diagnosed osteonecrosis and obtained the significant relationship between increased B.M.P. and the osteonecrosis. Increased bone marrow pressure provided both predictive and early diagnostic importance in even the preclinical stage of evolution of the disease, which subsequently had core biopsy proved osteonecrosis of femoral head. The results obstained were as follows; 1. Roentgenographically apperent osteonecrosis showed abnormal B.M.P. pattern, which were proved by the core biopsy. 2. In 21 cases of preclinical osteonecrosis, which did not show roentgenographic changes of osteonecrosis, measured B.M.P. parterns indicated as early stage of osteonecrosis in core biopsy at all. 3. The incidence of abnormal pressure pattern I was 51% and that of pattern II was 30%. 4. Enneking radiological staging did not correlate with the results of B.M.P. 5. The measurement of B.M.P. is relatively easy and simple method without any remarkable risk. The results of this study had great meaning in emphasizing the contribution of the bone marrow pressure measurement dianosing the preclinical stage of osteonecrosis, which had no roentgenographical changes and diagnostic symptoms.

Authors analylsed 384 hips of 269 patients with osteonecrosis of the femoral head in adult, who were diagnosed and treated between August 1976 and March 1986 at the Department of ()rthopaedic Surgery, Kyung Hee University Hospital. These are investigated in terms of history, clinical data and reontgenogram, retrospectively. In 269 patients, nontraumatic femoral head necrosis (NTFHN) were 199 patients (74.0%) and traumatic femoral head necrosis (TFHN) were 70 patients (26.0%). The male was more affected in ratioof 3.1: 1, especially higher in NTFHN about 4: l. In alcohol-induced necrosis all were male patients, but in polyvinyl pyrrolidone(PVP)-storaged cases 63% were female patients. The peak incidence of age distribution was at 6th decade(average 53.9 years) in the TFHN ahd 5th decade(average 44.2 years) in NTFHN). The most frequent probable etiologic frctor in NTFHN was idiopathic (71 patients, 35.8%), followed by alcohol-induced (68 patients, 34.2%), steroid-induced (27 patients, 13.6%) and PVP-storaged (19 patients, 9.5%). The bilateral involvement in NTFHN was 112 patients (53.6%). The idiopathic cases (42.0%) were lower than steriod-induced (81.9%), alcohol-induced (76.5%) or PVP-storaged (63.2%) in the bilaterality. The associated diseases in NTFHN were hepatopathy (12 patients), diabetes (7 patients), pulmonary tuberculosis (6 patients) and dermatopathy (5 patients). And the underlying diseases in steroid-induced were nephrotic syndrome (4 patients), arthralgia (4 patiehts), rhematiod arthritis (3 patients), dermatopathy (4 patients) and systemic lupus erythematosus (1 patient). 61.4% of TFHN was diagnosed within 2 years after trauma, 56.7% of NTFHN had the duration of symptom over one year. The initial reontgenogram stage according to Ennekings classification was average stage 1V. In NTFHN cases, there were no significant relationship between etiologic factors and initial reotgenographic stage or duration of symptom. But there were significant corelation between Enneking's reontgengraphic stage and clinical findings (range of movement of joint, Harris hip score, duration of symptom). In more severe cases than Enneking's radiologic stage IV, Harris hip score not provide any information to select a proper treatment.

Proximal tibial osteotomy is a procedure usually employed for osteoarthritis of the knee with a predominant single compartment involvement accompanied by pain and angular deformity. It has as its objective the shift of the gravitational line of weight from an involved to a relatively uninvolved side of the knee. We studied the preoperative clinical status and postoperative results in twenty-two patients (twenty-four knees) who had had a proximal osteotomy for osteoarthritic varus deformity. The mean length of follow-up was 2.6years(Range, 6months to 4.8years). In the preoperative evaluation of the lesion, we used bone scintigraphy to estimate the range and extent of the osteoarthritic change. The scintigraphic results were more sensitive to simple x-ray finding in a disease process. The range of motion of the knee were improved after osteotomy, from 7.7degree-128 degree to 2.6 degree-135degree(5.1degree in flexion contracture and 7 degree in further flexion). Correction of the tibiofemoral angle was performed to the level that we had decided correction angle to 7 degree and 3 degree of overcorrection. The correltion of good clinical results and tibiofemoral angle was dependent on whether the postoperative tibiofemoral angle is more than 5 degree valgus or not.

Buoy flap was useful method for soft tissue defect, bone defect or bone and soft tissue defect. Also the buoy flap could use monitoring for blood flow. The advantages of the buoy flap were long length of perforating cutaneous branch, large diameter of Peroneal vessel, transposition in same leg and the another advantage was that the fibula is the long, straight and mainly cortical bone. To obtain successful result of buoy flap, one must have the anatomic concept for vascular pattern (straight branch, proximal oblique branch, branch from muscular branch, distal oblique branch), relationships with surrounding muscles (between Peroneus m. and Soleus m., Through Peroneus m., through Soleus m.) and length of perforating branch. So, we studied total 19 person, 22 cases of buoy flap, who were admitted and took the operation at Kyung Hee University College hospital, from October 1985 to March 1987.

Acute unilateral vestibulopathy (AUV) is the recommended term [rather than the more widely used ‘vestibular neuritis (VN)’] for all pathologies involving sudden impairment of the unilateral peripheral vestibular function regardless of the exact location of the lesion. Acute vestibular syndrome (AVS) is an upper-level entity of AUV, which is the most common cause of AVS, and includes acute central vertigo. AVS typically presents with the symptoms of new onset continuous vertigo, gait instability, and nausea/vomiting lasting several days to weeks. The video head impulse test (vHIT) was recently developed and has been widely adopted at clinics and emergency centers. In this study, we will review the differential diagnosis of AVS using vHIT. In addition, we will describe the subtypes of VN and the use of vHIT for follow-up testing in AVS.

BACKGROUND: To provide some fundamental physiological basis for the physical training of pilots to improve orthostatic intolerance, cardiorespiratory responses to the symptom-limited maximal exercise loading were studied in pilots and non-pilots, and the results were compared. METHOD: Cardiorespiratory reponses to the symptom-limited maximal exercise loading by Bruce protocol was studied in 11 pilots and 11 matched controls (non-pilots). RESULTS: Comparisons of various data at maximal exercise in the pilots with those in the controls revealed that RR, VE/M2, VE/VO2, VE/VCO2, VT/VC and VE/MVV as well as HR, VO2, O2 pulse and AT showed no significant difference. CONCLUSION: The fact that the aerobic power in the pilots is not superior to that in the controls seems to emphasisze the necessity of aerobic endurance training along with muscular strength training to improve orthostatic tolerance of pilots flying modern high-performance aircrafts.
