Being a rare disease entity, there have been few references about the cleft hand in Korea. We evaluated the postoperative cosmetic results of 17 cleft hands in 14 patients, who were treated surgically at the Department of Orthopedic Surgery of Seoul National University Hospital, from 1982 to 1993. Among 14 patients, 8 were males. Bilateral cleft hands were in five patients and unilateral in 9. Three of five patients who had bilateral cleft hands, were treated surgically on both hands. Remaining two patients had an operation on one hand which affected more severely. Average age at the time of operation was 2 years and 5 months(5 months-10years). Average duration of follow-up was 34 months(1 year 1 month-7years 5 months). By Lange's classification, typical patterns were 16 hands and atypical pattern one. By Flatt's classification, there were 8 hands of I b, 7 I c, 1 I a, 1 II. One patient had family history whose father had both cleft hands and feet. Congenital anomalies other than cleft hand were associated in 10 of 14 patients. Two patients had 3 associated anomalies, 4 patients 2, and 4 patients one. Syndactyly was the most common associated anomaly of affected cleft hand. Central cleft was closed by Snow-Littler technique in 4 hands(24%), Barsky method in 12(71%) and others in 1(6%). Metacarpal bone was treated by intermetacarpal ligament reconstruction in 1 hand(6%), excision only 7(41%), transfer of 2(rd) metacarpal to 3(rd) metacarpal base after excision 5(29%), and 2(rd) metacarpal corrective osteotomy 3(18%). Complications were in 2 hands; one wound dehiesence of cleft, and one partial necrosis of skin. The cosmetic results of surgical treatment were graded into good, fair or poor by the parents-Good ; when parents were satisfied with the result, Fair; improved cosmesis but not satisfied, and Poor; no improvement after surgery. Good was in 16 hands and fair in one.

Neurilemoma is benign never-sheath tumor which has been described as painless mass and is usually discovered incidentally. It is the most common tumor of peripheral nerve origin and may arise in any nerve where Schwann cells occur. There are few domestic reports which were clinically evaluated in tens of cases of neurilemoma so far. We evaluated on the 56 cases of neurilemoma confined to the trunk and extremities, in the aspect of clinical characteristics, radiology, pathology, EMG, surgical treatment and postoperative results, who were surgically treated at the Department of Orthopedic Surgery of Seoul National University from 1984 to 1994. Among 56 patients, male were 29 and female were 27, and there was no sexual difference. The average age at surgical intervention was 46.4 years (16–83yrs) and 46.4% of patients were in the age of fourties and fifties. The anatomical locations of the tumors were as followed: upper extremities in 22(39%) cases, neck and supraclavicular area in 15(27%) cases, sacrum and lower extremities in 14(25%) cases and trunk in 5(9%) cases. Symptoms were palpable mass in 55 cases, local tenderness in 14, radiating pain in 11, pain in 10, paresthesia in 11, motor weakness in 2 cases. The average follow up period was 19.1 months(13–56 month). Median nerve was involved most frequently(14%), then ulnar nerve(11%). There was no cases which occurred in multiplicity or associated with neurofibromatosis. Marginal excision was done in 51 cases(91%), incisional biopsy only in 4 cases(7%), wide excision in 1 case. The size of the tumors in the longest axis was smaller than 2cm in 9 cases, between 2 and 4cm in 31 cases, between 4 and 6cm in 13 cases and more than 6cm in 3 cases. Malignant change or recurrence was not found in all cases.

It is known that the toe-flexors exert some power generation in ankle plantar flexion. However, there has been no paper published in which the power generation was quantified. The purpose of this paper, therefore, is to quantify the amount of contribution of the toe-flexors to the ankle plantar-flexion in normal and rapid walking using the kinetic data of three dimensional gait analysis system. In order to restrict the action of the toe-flexors, we designed special braces which can be applied to the forefeet of the examinee during walking. We performed the gait analysis in ten normal adult volunteers with and without braces, and evaluated the moment and power of toe-flexors during terminal stance and pre-swing phase of gait cycle. Gait analysis was done with the VICON 3-dimensional motion analysis system (VICON, Oxford Metrics, Oxford, England) and 2 force plates (AMTI, Advanced Mechanical Technoiogy, Newton, MA, U.S.A,). The kinetic results are as follows: l. Average speeds of normal and rapid walking were 1.12m/sec and 1.41m/sec respectiveIy. 2. In normal walking, peak ankle plantar-tlexion moment decreased 5.5% with braces, and sum of ankle plantar-flexion moment decreased 12.3% with braces. Both of the results were not significant statistically (p>0.05). Peak ankle power generation decreased 11.0% with braces, and sum of ankle power generation decreased 10.4% with braces. These decreases were also insignificant statistically (p>0.05). 3. In rapid walking, peak ankle plantarflexion moment decreased 26.7% with braces. The decrease was horderline significant statistically (p=0.062). The sum of ankle plantar-tlexion moment decreased 26.6% with braces, but the decrease was not significant statistically (p>0.05). Peak ankle power generation decreased 40.2% with braces, and sum of ankle power generation decreased 37.9% with braces. These decreases showed borderline significance statistically (p=0.062). In conclusion, toe-flexors may contribute about 10% of the total ankle plantar-flexion power generation, and the contribution will be increased with increase of walking velocity. We must be very careful to sacrifice the toe-flexors in cases with weak triceps power.

OBJECTIVE: Peripartum emergency cesarean hysterectomy of 28 cases at our hospital for 10years were reviewed that the clinical indication, history, and annual incidence change. METHODS: A retrospective descriptive analysis from January, 1988 to December, 1997 was carried out. RESULTS: There were 28 cases of emergency cesarean hysterectomy identified during this period among total 24, 689 deliveries. The annual incidence of emergency cesarean hysterectomy was significantly declined statistically(p<0.005). Cesarean hysterectomy was performed in 20 of 6, 671 cesarean section(0.30%) and in 8 of 18, 018 vaginal deliveries(0.04%), so more frequently after cesarean section than vaginal delivery. The cesarean hysterectomy rate was more frequent in multiparous women(0, 22%) than in nulliparous women(0, 02%). The most common indication of cesarean hysterectomy was 13 cases of uterine atony(46%), followed by 5 cases uterine rupture(18%), 5 cases of placenta previa with placenta accreta(18%), 3 cases of placenta previa(11%), 2 cases of uterine myoma(7%). No significant difference in length of operating time, amount of blood loss and operative complications were found between total abdominal hysterectomy and subtotal hysterectomy. The all patient who had cesarean hysterectomy recieved from 1200ml to 15840ml of blood transfusion with a mean of 3673ml. In aspect of fetal outcome, 3 cases of FDIU(Fetal death in utero) in uterine rupture and 1 case of stillbirth in preterm were found. The maternal complications were wound disruption, DIC, wound hematoma, ureter injury, vaginal stump bleeding, UTI(Urinary tract infection) and retroperitoneal bleeding, CONCLUSION: We conclude that the incidence of emergency cesarean hysterectomy declined with prediction of antenatal risk factor, preparing of sufficient fresh blood, prophylactic antibiotics, vigorous uterotonics and close observation after delivery.

Limb-body wall malformation complex(LBWC), also know as the amniotic band syndrome, is a poorly defined, sporadic group of congenital anomaly characterized by a collection of protean fetal malformation, deformation and disruption. Accurate diagnosis is often difficult because of its variable presentation pattern and the absence of exactly same case. We report two autopsy cases. One revealed body wall, cardiac, and craniofacial anomalies with anencephaly, and amniotic adhesive band attached to craniofacial defect of the fetal part without evidence of amniotic rupture. The other exibited abdominal wall defect with omphalocele, visceral, postural, and limb anomalies together with neural tube defect in the lumbosacral region. The pathogenesis of this syndrome was discussed in detail.

BACKGROUND: It is well known that systemic blood pressure oscillates with low(0.04~0.1Hz), mid(0.1~0.15Hz), and high(respiratory) frequency range. But there has been no study about oscillation of pulmonary artery pressure(PAP). METHOD: We measured PAP for 5 minutes in 32 patients of ventricular septal defect and stored them to computer files. Power spectral density curve was obtained. Low, mid, respiratory frequency power were measured by integrating the area within each frequency range below the power density curve. RESULT: The incidence of significant low frequency power(more than 5% of total power) were higher in patients of high PAP and hign Rp/Rs than those of low PAP and Rp/Rs(p<0.01 and p<0.005 respectively). The low frequency power positively correlates with PAP and Rp/Rs(r=0.62, p<0.0005 and r=0.61, p=0.0005 respectively). CONCLUSION: It can be said conclusively that as PAP and pulmonary vascular resistance elevates, the PAP tends to definitively oscillate in low frequency range.

PURPOSE: Headache is a frequent symptom in pediatric practice, but the prevalence of chronic recurrent headache was estimated in several studies with wide variations, because of inadequate expression and differences in case definition in children. Headache classification of International Headache Society is usually used in adults, but the application of it to children is uncommon, so we tried to diagnosis children with headache by using International Headache Society Classification. METHODS: We analyzed the clinical pictures, physical examinations including neurologic examination, PNS series, EEG and CT or MRI in 53 children with nonprogressing recurrent headache over than one month, who visited to pediatric department of Dong-A University hospital from January, 1995 to Feburary, 1996 and diagnosed them by using International Headache Society Classification. RESULTS: 1) The sex ratio between male and female was 1:1.2. 2) Diagnosed groups consisted of children with migraines in 22 cases(41.5%), tension-type headache in 19 cases(35.9%), coexisting migraine and tension-type headaches in 5 cases(9.4%), miscellaneous headaches not associated with structual lesion in 1 case(1.9%), headache associated with vascular disorders in 2 cases(3.8%), headache associated with nonvascular intracranial disorder in 1 case(1.9%), headache due to facial pain in 3 cases(5.6%). 3) Of 22 migraine cases, 13 cases(59.1%) had migraine with aura, 8 cases(40.9%) have migraine without aura and of 19 tension-type headache cases, 8 cases(42.1%) have episodic type, 11(57.9%) cases have chronic type. 4) Of 53 cases with recurrent headache, 3 cases(6%) had abnormal findings in CT or MRI. 5) Of 53 cases with recurrent headache, 9 cases(17%) had abnormal findings in EEG. CONCLUSIONS: International Headache Society Classifications are useful, but the diagnostic criteria are too strict for children, especially in migraine and tension type headache.

Ankle sprain is one of the most common musculoskeletal injuries. Although most ankle sprains respond well to conservative measures, chronic instability following an acute sprain has been reported to occur in 20% to 40% of patients. Some individuals are eventually indicated for a lateral ankle ligament reconstruction due to persistent ankle instability. More than 80 surgical procedures have been described to address lateral ankle stability. These range from direct repair of the anterior talofibular ligament (ATFL) and of the calcaneofibular ligament (CFL) to reconstructions based on the use of autograft or allograft tissues. However, the best surgical option remains debatable. The modified Broström procedure is most widely used for direct ligament repair, but not always possible because of the poor ATFL or CFL quality or deficiency of these ligaments, which prevents effective shortening imbrication. Furthermore, the importance of a CFL reconstruction has been emphasized recently. On the other hand, it is difficult to achieve an efficient CFL reconstruction during the Broström procedure. Others have reported that an anatomic reconstruction of injured ligaments restores the normal resistance to anterior translation and inversion without restricting subtalar or ankle motion, and as a result, anatomic reconstructions for lateral ankle instability utilizing an autograft or allograft tendon have gained popularity.

To analyze the improvement of shouder function after arthroscpic subacrominal decompression and open repair for complete rotator cuff tear, we performed a prospective study in 14 patients using self evaluation form from the American Shouder and Elbow Society(ASES). All patients were treated with arthrscopic biplanar subacromial decompression and open repair by use of bony trough and followed for more than 1 year from November 1994 to June 1996 in Dankook university hospital. All patients were assessed preoperatively and at final follow-up using the standardised method of research committee of American shoulder & elbow surgeons. Tears of the rotator cuff were divided into medium(8 shoulders), large(3 shoulders) and massive(3 shoulders). Most of the patients were heavy laborers. Average age was 56.2 years (51-73 years). There were 9 male and 5 female patients. The dominant arm was affected in 8 shoulders. Postoperative abduction brace was used in all cases and passive range of mortion exercise was started from postoperative third day. At average follow-up of 17 months, average pain scores decreased to 0.8+/-1.1 from 6.9+/-2.3. Scores of ASES evaluation form increased to 87.3+/-12.2 from 35.8+/-16.3(p<0.05). As to the range of mortion, only internal rotation improved from T12 to T8(p<0.05). Thirteen patients achieved excellent or good result. Twelve patients returned to initial occupations. Arthroscopy is helpful to define the tear size which may affect the surgical approach and open repair by use of bony trough and tunnel is useful to recovery of shoulder function.

Discoid meniscus is a congenital morphological variable anomaly of meniscus which is often asymptomatic. Arthroscopic surgeries on 91 symptomatic lateral discoid menisci of 84 patients were performed at the Department of Orthopedic Surgery, Seoul National University Hospital during the period of Jan. 1987 to Jan. 1994, which equals 19.2% of arthroscopic meniscectomies performed. Follow up was done from minimum of 1 year to maximum of 8 years, with an average period of 3 years and 10 months. Retrospective study was done with the review of clinical records, roentgenograms, MRI, and arthroscopic findings on recorded videotapes to evaluate the clinical and radiological features, results of arthroscopic treatment and possible prognostic factors. The followings are the results: 1. The lateral discoid meniscus encompassed 19.2% of arthroscopic meniscectomies performed at the same period, which was relatively high incidence. Arthroscopic partial and subtotal menis- cectomy resulted in satisfactory results. 2. Since 8 (11%) knees were not diagnosed preoperatively as discoid meniscus due to type being incomplete or torn meniscus displacement, these points should be considered with clinical findings at diagnosis of discoid meniscus. 3. 34.9% of 83 menisci with tear had previous trauma history which showed high vulnerability to tear. Discoid menisci without tears but with grade II intrasubstance increased signal and symptoms were treated with arthroscopic meniscectomy and showed good results. Therefore discoid menisci without tears should be considered of arthroscopic meniscectomy in the presence of clinical symptoms and MRI findings. 4. Lysholm total and pain scores were significantly improved at postop. 1 year and at the final follow up with p<0.05. Factors such as degenerative changes, sex, age, duration of preoperative symptoms, presence of tears and types of meniscectomy gave no significant influence on the results and the prognosis.
