Stature is an essential component of biological profile analysis since it determines an individual's physical identity. Long bone dimensions are generally used to estimate the stature of skeletal remains; however, non-long bones such as the sternum, cranium, and sacrum may be necessary for some forensic situations. This study aimed to generate a regression equation for stature estimation of the skeletal remains in the Thai population. Ten measurements of the sacrum were measured from 200 dry sacra. The results revealed that the maximum anterior breadth (MAB) provided the most accurate stature prediction model among males (correlation coefficient [r]=0.53), standard error of estimation (SEE=5.94 cm), and females (r=0.48, SEE=6.34 cm). For the multiple regression model, the best multiple regression models were stature equals 41.2+0.374 (right auricular surface height [RASH])+1.072 (anterior-posterior outer diameter of S₁ vertebra corpus [APOD])+0.256 (dorsal height [DH])+0.417 (transverse inner diameter of S₁ vertebra corpus [TranID])+0.2 (MAB) with a SEE of 6.42 cm for combined sex. For males, stature equals 63.639+0.478 (MAB)+0.299 (DH)+0.508 (APOD) with a SEE of 5.35, and stature equals 75.181+0.362 (MAB)+0.441 (RASH)+0.132 (maximum anterior height [MAH]) with a SEE of 5.88 cm for females. This study suggests that regression equations derived from the sacrum can be used to estimate the stature of the Thai population, especially when a long bone is unavailable.

This study was performed to assess the efficacy of manipulation for the sacroiliac joint subluxation patients. The subjects of this study ware 8 patients with sacroiliac joint subluxation who visited the out patient department of the physical therapy wooridul clinic, from January 1, 2005 through July 3, 2005. To find out the effect of manipulation, we sampled 8 patient treated with manipulation(Thompson technique), using by radiographic. All patients were treated 2days a week for 12 weeks. The results after 12 week treatment, compared with before treatment, were as follows : 1. The improved in sacrum lateral subluxation in the manipulation after 12 week treatment was very significant(p<.01) 2. The improved in sacrum rotation subluxation in the manipulation after 12 week treatment was significant(p<.05) 3. The improved in lumbo-sacral anger subluxation in the manipulation after 12 week treatment was very significant(p<.01).

Caudal regression syndrome (CRS) is a rare neural tube defect that affects the terminal spinal segment, manifesting as neurological deficits and structural anomalies in the lower body. We report a case of a 31-month-old boy presenting with constipation who had long been considered to have functional constipation but was finally confirmed to have CRS. Small, flat buttocks with bilateral buttock dimples and a short intergluteal cleft were identified on close examination. Plain radiographs of the abdomen, retrospectively reviewed, revealed the absence of the distal sacrum and the coccyx. During the 5-year follow-up period, we could find his long-term clinical course showing bowel and bladder dysfunction without progressive neurologic deficits. We present this case to highlight the fact that a precise physical examination, along with a close evaluation of plain radiographs encompassing the sacrum, is necessary with a strong suspicion of spinal dysraphism when confronting a child with chronic constipation despite the absence of neurologic deficits or gross structural anomalies.

Purpose: This study was done to examine the prophylactic effect of transparent film dressing on the sacrum and coccyx sites to reduce pressure ulcers. Methods: The participants were 317 patients admitted to an SICU in Seoul, Korea. Of the patients, 175 were assigned to the experimental group and 142 to the control group. For participants in the experimental group, a prophylactic transparent film dressing was applied on the sacrum and coccyx. The control group received the usual care. The nurses checked for pressure ulcers on the sacrum and coccyx at least once every duty. When pressure ulcer occurred, it reported on the record form. The results were analyzed using Poisson and Hierarchical logistic regression. Results: The prevalence and risk of pressure ulcer was lower in the experimental group compared to the control group but the difference was not significant. The ICU length of stay was significantly associated with pressure ulcer risk. Conclusion: Findings indicate that prophylactic transparent film dressing helps to reduce pressure ulcer in SICU patients.

The purpose of this study was to characterize the impact shock wave and its attenuation, and the kinematic response of the lower extremity's joints to the impact shock during downhill running in which the lower extremity's extensor acts dominantly. For this study, fifteen subjects(mean age:$27.08{\pm}4.39$; mass:$76.30{\pm}6.60$; height:$177.25{\pm}4.11$) were required to run on the 0% grade treadmill and downhill grades of 7%, and 15% in random at speed of their preference. When the participant run, acceleration at the tibia and the sacrum and kinematic data of the lower extremity were collected for 20s so as to provide at least 5 strides for analysis at each grade. Peak impact accelerations were used to calculate shock attenuation between the tibia and sacrum in time domain at each grade. Fast Fourier transformation(FFT) and power spectral density(PSD) techniques were used to analyze impact shock factors and its attenuation in the frequency domain. Joint coordinate system technique was used to compute angular displacement of the ankle and knee joint in three dimension. The conclusions were drawn as fellows: 1. Peak impact accelerations of the tibia and sacrum in downhill run were greater than that of 0% grade run, but no significant between conditions. Peak shock of PSD resembled also in pattern of peak impact acceleration. The wave of impact shock attenuation between the tibia and sacrum decreased with increasing grade, but didn't find a significant difference between grade conditions. 2. Adduction/abduction, flexion/extention, and internal/external rotation of the ankle and knee joints at support phase between grade conditions didn't make much difference. 3. At grade of 7% and 15%, there were relationship between the knee of the flexion/extension movement and peak impact acceleration during heel strike and found also it in the ankle of plantar/dorsiflexion at grade of 15%.

Purpose: This study was performed to identify skin hydration status and skin surface pH according to the body parts of the aged with immobilization. Methods: The subjects were 101 aged patients in a hospital and a institution for the elderly in Seoul. Data for skin hydration and skin surface pH were collected using corneo-meter and skin pH-meter. The body parts of measurement were 10 parts; face, forearm, back of the hand, flank, upper abdomen, leg, back of the foot, heel, scapular, and sacrum. The data were analyzed by SPSS/WIN 12.0 program. Results: Skin hydration status were relatively low especially on lower extremity and back of body, and skin surface pH of scapular and sacrum were high. There was significant negative correlation between skin hydration status and skin surface pH on the 6 body parts. Conclusion: Skin hydration status and skin surface pH, especially on scapular, sacrum, and lower extremity need to be considered as important control factors for increasing skin health status of the aged with immobilization.

Sacral schwannoma is a rare lesion with a tendency to reach large proportions. The benign schwannoma rarely involves the vertebral bodies extensively. The authors report a case of giant intrasacral schwannoma in 30-year-old woman who had intermittent lower back pain during 3 years period. CT and MRI showed a destructive mass lesion within the upper part of sacrum with a large mass extending into the presacral space. The patient underwent combined surgery consisted of anterior transabdominal approach and posterior sacral laminectomy and total removal of tumor. The characteristics of the lesion were discussed with a review of literatures.

We present a rare case of fracture-dislocation at the level of the first sacral (S1) and second sacral (S2) vertebrae. The S1 was displaced forward into the pelvic cavity and was located just in front of the S2. Because the patient also had extensive neurological injury to the lumbar plexus and instability of the pelvic ring, surgery to stabilize the pelvis and to decompress the lumbar plexus was performed. The surgery was successful and the patient experienced marked improvement in neurological function.

Bone metastasis of hepatocellular carcinoma appears to be peculiar when clinical manifestation of liver disease is not apparent, and initial diagnosis of metastatic hepatocellular carcinoma by fine needle aspiration cytology is rarely obtained. We experienced a case of 45-year-old man with metastatic hepatocellular carcinoma in the sacrum, which was diagnosed by fine needle aspiration cytology. The intrahepatic mass, measuring 1.2 cm in diameter and kept unchanged in size for two years, was never proved to be hepatocellular carcinoma histopathologically. The aspirated neoplastic cells were mostly in sheets, showing abundant acidophilic cytoplasm and large, round, centrally located nuclei with single, prominent acidophilic mucleoli. In the cell block section, diagnosis of metastatic well-differentiated hepatocellular carcinoma was made without difficulty, and definite trabecular fashion with sinusoidal endothelial cell lining was found.

The perineum is comprised of diverse anatomic structures with mixed sympathetic and somatic innervation. The coccyx is innervated by the coccygeal nerves and branches of the fifth sacral root. Recently, ganglion impar block has been introduced as an alternative means of managing intractable pain of sympathetic origin, coccygodynia by trauma, tenesmus and perineal hyperhydrosis. We managed a 59-year-old female patient who had suffered from perineal pain by metastasis of cervical cancer. Approach to impar ganglion through the anococcygeal ligament was impossible because her coccyx was hyperflexed anteriorly by old fracture. But we could perform ganglion impar block successfully by approach through the separation of sacrum and coccyx.
