Three treated groups totaling 60 patients with solitary bone cysts were evaluated. Curettage and bone graft, methylprednisolone acetate (MPA) injection, and curettagehydroxyapatite (HA) filling were performed in 20, 32, and 12 patients, respectively. Four patients were treated with two different interventions. The healing rates (complete healing plus incomplete healing evaluated by Campanacci's criteria) in the three groups was 85%, 83%, and 100%, respectively. Although the healing rate of HA filling appeared to be best in this series, the average duration of follow-up was less than two years. Therefore, MPA injection should be the preferred method for its greater simplicity and the absence of complications.

Many authors have reported that disc herniation can be resorbed by monocytic phagocytosis. However, how the recruitment of monocytes is triggered is still unknown.We investigated monocyte chemoattractant protein-1 (MCP-1) by using the experimental rat model in vivo and rabbit model in vitro to ascertain the precise mechanism of macrophage recruitment in the early phase of disc resorption.The autologous intervertebral discs from tails of Wister rat were subcutaneously implanted into the abdomen. These discs were used for immunohistochemical study. Additionally, we employed tissue culture models of rabbit's discs, and the quantification of MCP-1 in these media was performed.MCP-1 positive disc chondrocytes were observed in the nucleus pulposus and the inner annulus fibrosis on the third day. Monocyte derived macrophages were considerably observed around the intervertebral disc by the seventh day. The MCP-1 induced by rrlL-1β or rrTNFα indicated its peak volume at 12 hours and at 18 hours after incubation.Our study suggests that intervertebral disc chondrocytes have chemotactic properties and play an active role in the recruitment of monocytes involved in disc resorption. Moreover, inflammatory cytokines induce and regulate the production of MCP-1 in the intervertebral disc cells.

Neurovascular compression in the thoracic outlet produces great variation of signs and symptoms. The clinical picture is often complex, being made up of the derangement of blood vessels, somatic nerves and autonomic nervous networks in varying degrees. Thirty-eight of the 150 patients (25%) treated in our clinic because of possible thoracic outlet syndrome (TOS), complained of general malaise such as headache, dizziness, sleeplessness, nausea, anorexia or general fatigue, in addition to their peculiar signs and symptoms due to brachial plexus involvement.In order to find out whether or not autonomic nerve dysfunction can be demonstrated in patients with TOS, a non-invasive and quantitative technique was developed for assessing the mean (M) and coefficient of variations (CV) of R-R intervals in ECG at resting position. Thirty patients (13-39; mean 29.5 y/o) were put into two groups of 15 patient s each. In the first group patients with autonomic nerve disorder had complaints of general discomfort, M was 803.72 ± 106.9 msec and CV was 3.214±0.717%. In the second group, those without general discomfort, M was 972.21 ± 120.64 msec and CV was 5.926±0.720%. The first group had a significantly shorter M (P < 0.001) and smaller CV (P < 0.001) compared to the second group. Furthermore, in two cases in the first group diagnosed by psychologists as having schizophrenia and anxiety neurosis, it was found that their M and CV were the nearly same as those in the second group.Decompressive ope r a tions were performed on five patients in the first group. Their complaints decreased or vanished after the operation and the M and CV progressed to near the normal rate.From these results, we belive that this method in useful in differentiating between autonomic nervous disorders and psychological disorders; and that in patients with TOS, a decompressive operation can help eliminate complaints of general discomfort due to autonomic nervous disorders.

We report the diagnostic utility of diffusion-weighted MR images in primary soft tissue tumors. Diffusion-weighted echo-planar imaging was performed in seventy-seven patients with primary soft tissue tumors (benign: 37 cases, malignant: 40 cases). The apparent diffusion coefficient (ADC) was determined from each image. The average ADC of benign cases was 1.53±0.26, and that of malignant soft tissue tumors was 1.31±0.63. In addition, except for three giant cell tumors of soft parts and 11 myxoid type sarcoma cases, ADC of benign soft tissue tumors was 1.58±0.19, and that of malignant soft tissue tumors was 0.94±0.19. This malignant soft tissue tumor ADC valve was significantly lower than that of the benign tumor group (p<0.0001). This indicates that diffusion-weighted imaging is useful in the differential diagnosis of primary soft tissue tumors.

The purpose of this research was to clarify the causes of numbness and pain by traction of the upper limbs. We stretched the nerves in the upper limbs of rats by utilizing the flail of the shoulder girdle, and measured the blood flow of the brachial plexus and the median nerve. The model animals,32 wistar rats, were inserted with steel lines to the radius and ulna. These steel lines were drawn in the direction of a shoulder abduction of 80 degrees. A decrease and recovery of the blood flow were measured using the hydrogen gas clearance method.The blood flow of the subepineural space in the brachial plexus decreases sharply in conditions with looseness of the plexus.The blood flow of the intrafuniculuse in the brachial plexus decreases like a straight line in those states without looseness of the plexus. The blood flow of the subepineural space in the median nerve decrease like a straight line, too. The decrease rate of the subepineural space was sharper than that of the intrafuniculuse. As for the recovery rate, there was no significant difference in either site.One of the factor that causes nervous and functional imbalance with a slight traction is a sharp reduction of the blood flow in the subepineural space of the brachial plexus.

We recently had two rare cases of a stress fracture in the lower extremity. The first case was a 14-year-old sprinter who suffered a stress fracture of the medial malleolus. The second case was a 15-year-old baseball player who had an initial stress fracture in the femur and later stress fracture in the ipsilateral tibia. We shortly discussed about these cases.

We review the clinical results of 19 cases with intramuscular hemangioma. Subjects included 6 males and 13 females ranging in age from 5 to 58 years (median, 23 years). The tumor was located in the upper extremities in 3 patients, the trunk in 3, and the lower extremities in 13. Pain on motion was found in 17 patients (89.5%) and limitation in motion range was reported in 60%. Surgical planning was done using MRI and a wide surgical margin was used in regard to the affected muscle and a marginal margin for surrounding tissues. The excision was performed in all patients and no recurrence was found in the duration of follow-up ranging from 7 to 101 months (median, 57 months). Furthermore, the limitation of motion was completely improved and the postoperative disability such as gait disturbance was not noted. Thus, the wide surgical excision of intramuscular hemangioma achieved satisfactory results.

(Purpose)We Studied the diagnosis and surgical management of suprascapular nerve entrapment neuropathy in athletes.(Materials and methods)Eighteen patients with infraspinatus muscle atrophy were studied. Fourteen were men and 4 women. Their mean age was 27 (range 14 to 40) years. The diagnosis was confirmed by physical and electromyographic examinations. As an ancillary test, MRIs of the shoulder joint were obtained. Those patients with rotator cuff tear were excluded from this study.(Results)Electromyographic examinations showed an abnormality in 8 patients. Two of them had isolated paralysis of the infraspinatus muscle. We operated on 4 patients with suprascapular nerve entrapment. We performed a release of the superior scapular transverse ligament on 2 patients with paralysis of the supraspinatus and infraspinatus muscles, a shaving of the spinoglenoid notch on a patient with isolated paralysis of the infraspinatus muscle and removed the ganglion cyst in 1. All the patients had good results, however, they needed 1 or 2 years to recover from paralysis.(Conclusion)Early diagnosis and treatment are important for the management of suprascapular nerve entrapment neuropathy in athletes.
