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.

OBJECTIVE: To describe normal postoperative MR findings and MR findings of postoperative discitis in patients who underwent operation due to herniated intervertebral disc. MATERIALS AND METHODS: We retrospectively reviewed normal postoperative MR findings and MR findings of discitis in 30 patients(21-61yrs.) (13 cases dignosed as discitis and 17 cases as normal) who previonsly underwent laminectomy and discectomy, or bony fusion. We analyzed signal intensity of end plate and disc, end plate destruction, and enhancement of end plate and disc on T1- and T2-weighted images(WI) of 1.5T MRI. RESULTS: Among 14 out of 17 patients with no evidence of discitis, 7 patients showed high signal of the posterior portion of disc on T1- and T2-WI and 11 patients revealed enhancement at the same sites. In all 13 patients suspected of having discitis, end plate and disc showed low signal on T1-WI, high signal on T2-WI, heterogeneous enhancement, and irregular destruction of end plate. Meanwhile, 3 cases with no evidence of postoperative discitis clinically who underwent bony fusion showed similiar findings to those of the above 13 patients, except for homogeneous enhancement of end plate and vertebral body. CONCLUSION: The MR findings of postoperative discitis were low signal on T1-WI, high signal on T2-WI, and heterogeneous enhancement of and plate and disc, and destruction of end plate.

OBJECTIVE: The purpose of this study was to describe the MR imaging appearance of the dural ligaments which is connected between the anterior dura mater and the posterior longitudinal ligament. MATERIALS AND METHODS: In 10 cadavers with formalin fixation, the dural ligaments were evaluated and photographed after removal of the posterior element of the spinal canal. MR studies of 12 patients who had distinct dural ligaments were evaluated. Spin-echo MR images were obtained on a 1. 5T unit. RESULTS: In seven of the ten cadavers, the midline dural ligament was observed; the lateral dural ligament was observed in 3 cadavers. On MR, the dural ligaments were imaged as thin lines of low signal intensity between the anterior dural margin and the posterior longitudinal ligament. Dural ligaments were well-visualized at the level of the lower lumbar spine which had a more prominent anterior epidural space than that of the upper level of the spine. Eight of 12 cases had well developed midline dural ligaments. Two cases showed distinct lateral dural ligaments and the remaining 2 cases had distinct midline and lateral dural ligaments. CONCLUSION: MR images of the dural ligament demonstrate a thin low signal line at the anterior epidural space.

Reiter's syndrome is described as an inflammation of the joints and tendon attachments at the joints, and is often accompanied by an inflammation of the eye;s conjunctiva and the mucous membranes, such as those of the mouth, urinary tract, vagina, and penis, and by a distinctive rash. Ossification of the yellow ligament associated with Reiter's syndrome has never been reported A 41-year old male patient with Reiter's syndrome was admitted to our hospital due to cervical myelopathy caused by ossification of yellow ligament. He was treated with laminectomy and fusion, from C3 to C7, by using a lateral mass screw and plate fixation. Laminectomy and fusion seems to be an appropriate treatment option for cervical myelopathy due to ossification of yellow ligament.

Surgical correction of adult spinal deformity is a challenge, and is physically and mentally demanding for spinal surgeons. For satisfactory surgical outcomes, proper patient selection is fundamental and preoperative detailed physical examination, intra-operative neuromonitoring, and collaboration with anesthesiology or internal medicine department are critical for prevention of peri-operative complications associated with surgical treatments. A posterior-only or anterior-posterior combined approach can be used. Considering the patients' hemodynamic status or long-time anesthesia, surgeons can decide whether to operate by stage or one stage. Deformity correction can be performed using spinal osteotomy or anterior interbody fusion. Decision regarding correction method depends on the patient's condition and correction degree or level. In this review, the authors try to help in decision making with regard to deformity correction methods for ideal surgical technique, correction angle, fusion length etc. in reference to previous literature.

Odontoid process fracture, nonunion or atlantoaxial instability are generally treated with posterior fusion using sublaminar wiring techinique. And occiput to C2 fusion is performed in cases with posterior arch defect of atlas. However, occiput to C2 fusion can not stabilize unstable C1-2 segment before accomplishment of fusion. Therefore, postoperative external support is necessary. A 48-year old male patient visited our hospital due to weakness and spasticity of four extremities. 6 months ago, he got C1-2 fusion in other university hospital due to odontoid process fracture. 6 months after surgery, sublaminar cable was pulled out and grafted bone was absorbed. The neurological deficits were worsened(spasticity of four extremities with severe myelopathy, bed ridden state). JOA score was 4. Diagnosis of the patient was C1-2 instability with cervical myelopathy due to odontoid process fracture nonunion and posterior arch defect of atlas. C1-2 transarticular screw fixation and occiput to C2 fusion were performed.
