This is to report a case of surgical and orthodontic of posterior scissor bite, deep bite and gummy smile by the segmental osteotomies. The surgical thechnics procedures used are Peterson's mandibular posterior segmental osteotomy, modified $K{\ddot{o}}le$ technic for mandibular anterior segment and Wunderer's maxillary anterior segmental osteotomy. The results are as follows : 1) Peterson's mandibular posterior segmental osteotomy could be achieved by the buccal approach with some difficulties in accessbility. 2) Upper and lower anterior segmental osteotomies were followed separately to correct the deep curve of Spee, deep bite and gummy smile in shortened period. 3) All alveolar segments were immobilized in preplanned position by the prefabricated palatal and lingual resin splint, therefore intermaxillary fixation was not necessary.

Purpose : The purpose of this study is to find out the evidence concerning the effectiveness of manual therapy intervention in the treatment of low back pain related to spondylolisthesis Methods : 12men with lumbar pain from L5~S1 spondylolisthesis of 2 or 3 grade were treated during 12-week period. The manual therapy applied twice per week. The results of back and radiating pain were measured by VAS, and abdominal muscle strength was measured by Power track II. The measurement of degree of slip in spondylolisthesis was confirmed by the lateral view of X-ray and took a measurements of the anterior displacement of a vertebral body in relation to the vertebral below. Results : 1. There was significant decrease in the back and radiating pain.(p<0.05) 2. There was significant increase in the abdominal muscle strength.(p<0.05). 3. There was significant decrease in the degree of the anterior displacement. Conclusion: The intervention of manual therapy for lumbar spondylolisthesis is effective in back pain, radiating pain, abdominal muscle strength and degree of the anterior displacement. So, nonsurgical treatment should be attempted before surgical treatment.

A rare case of ruptured aneurysm associated with multiple $A_1$ fenestrations resembling plexiform network was demonstrated by 3D angiography. A 56-year-old female presented with a ruptured aneurysm in the $A_2$ segment of the left distal anterior cerebral artery associated with the right $A_1$ fenestration. The ruptured aneurysm was occluded with surgical neck clipping via interhemispheric approach without neurological deficit. Plexiform fenestrations of the right distal $A_1$. opposite side to the left ruptured $A_2$ aneurysm, were clearly visible on postoperative 3D angiography. Our case may strongly support the theory described by Paget, namely that a remnant of the plexiform anastomosis between the primitive olfactory artery and $A_1$ segment is the source of such fenestration.

Ossification of the posterior longitudinal ligament (OPLL) in the thoracic spine is rare, even in the Far East. A 45-year-old female presented with a 4month history of progressive motor weakness in the lower extremities, numbness below the midthoracic area, and spastic gait disturbance. Neuroradiological examinations revealed massive OPLLs at the T4-T6 levels with severe anterior compression of the spinal cord. Anterior decompressive corpectomies with bone grafts were performed from T4 to T6 using a trans-thoracic approach. After surgery, the patient made an uneventful recovery. However, eleven years after surgery, the patient developed recurrent lower extremity weakness and spastic gait disturbance. De novo OPLLs at the C6-T2 levels were responsible for the severe spinal cord compression on this occasion. After second surgery, paralysis in both legs was resolved. We present a rare case of late cervicothoracic OPLL in a patient surgically treated for thoracic OPLL.

Facial skeletal remodeling was revolutionized more than 30 years ago, by the work of Tessier and other craniofacial surgeons. However, the need to correct the skeleton in the upper third of the face is not frequently diagnosed or treated in aesthetic facial surgery. Here, we report on the aesthetic correction of a protrusive forehead. A patient visited our hospital for aesthetic contouring with a prominent forehead. The anterior wall of the frontal sinus was removed with a craniotome via the bicoronal approach. After the excised bone was repositioned, it was fixed with a titanium mesh plate and screws. An electric burr was used to contour the supraorbital rim and frontal bone. Once the desired shape was achieved, the periosteum was replaced, and the wound was closed in layers. When performed properly, frontal sinus contouring could significantly improve the appearance in patients with a prominent forehead. Plastic surgeons must carefully evaluate patients with a prominent forehead for skeletal remodeling that involves the accurate and safe repositioning of the anterior wall of the frontal sinus.

Purpose : The purpose of this study was to determine the changes in ultrasound imaging of the lower limbs in patients with degenerative osteoarthritis who received a total knee replacement (TKR). Methods : The participants for the study were ten patients who were to receive a total knee replacement. Measurements were taken a total of three times: before receiving a total knee replacement, and one week and two weeks after receiving a total knee replacement. The vastus medialis, rectus femoris muscle, tibialis anterior and gastrocnemius muscle were measured using ultrasound imaging. Results : Muscle thickness of the vastus medialis, rectus femoris muscle, tibialis anterior and gastrocnemius muscle had no significant interaction over time whether surgery was performed or not. White area index (WAI) and density of vastus medialis, rectus femoris muscle, tibialis anterior and gastrocnemius muscle had no significant interaction over time whether surgery was performed or not. Conclusion : In conclusion, lower quality muscles were due to a decrease in muscle fiber and an increase in fat fiber. Therefore, initial physical therapy after total knee replacement should consider this point and be designed appropriately as a therapeutic approach for total knee replacement patients.

It has been known that the ankle arthrodesis is a common surgical procedure for treating the ankle arthrosis and deformity that do not respond to the non-operative treatment. To date, various surgical techniques for the ankle arthrodesis have been reported. Clinical and biomechanical trials have shown that the rigid internal fixation leads the increased rate of the union. The ankle arthrodesis may be complicated with the nonunion, delayed union, malunion, and infection. In cases of the Charcot joint of the ankle in diabetic patients, however, arthrodesis could reduce the disadvantage of the nonoperative treatment, such as the loss of the reduction, progressive collapse, multiple ulcerations and infection. The object of this case report is to report our experience of a successful ankle arthrodesis using an anterior T plate in treating the unstable ankle of a diabetic patient, associated with the ankle fracture and the neuropathy. The surgical approach of this technique is simple so that it would allow less soft tissue injury, and this procedure would be regarded as one alternative to provide the rigid internal fixation in the ankle arthrodesis.

The endoscopic endonasal approach (EEA) to the craniovertebral junction (CVJ) has recently been considered a safer alternative and less invasive approach than the traditional transoral approach because the complications associated with the latter are avoided or minimized. Here, we present two challenging cases of CVJ pathologies. The first case involved os odontoideum associated with anterior displacement of the occipitocervical junction where the EEA was used, followed by C0-C1-C2 fusion using a posterior approach to decompress the CVJ, and was complicated by rhinorrhea and Candida albicans meningitis. The second case involved basilar invagination with syringomyelia previously treated using a posterior approach, where aggravation of neuropathic symptoms required combined treatment with EEA and occipitocervical fusion of C0-C2-C3-C4, with the postoperative course challenged by operative site infection requiring drainage with debridement and antibiotic therapy. The EEA is an alternative approach for accessing the CVJ in well-selected patients. Knowledge of EEA complications is crucial for the optimal care of patients.

Purpose: Since an injured elbow joint can disturb the activity of daily life by limiting motion, especially if the motion is restricted over 40 degree of flexion contracture and under 105 degree of further flexion, it is imperative to select the best method and the timing of treatment of the elbow stiffness. Therefore this review will discuss open surgical techniques for stiff elbows based on the literature. Materials and Methods: It is important to take sufficient clinical examination of the patient, including history taking. And, a surgeon should select appropriate procedure after accurately understanding about the status and cause of the stiff elbow with radiographic methods. Surgical methods include arthroscopic release open release, distraction arthroplasty, total elbow replacement and there are four approachs in the open release - anterior approach, medial "over the top" approach, limited lateral approach: column procedure, posterior extensile approach-. Results and Conclusion: Although at present the arthroscopic technique is emphasized for the treatment of elbow stiffness, a surgeon should know conventional open techniques.

With the increasing number of primary ACL reconstructions, revision surgery has become more frequent. Despite arthroscopic technique and treatment advancements, the current methods of reconstruction are far from perfect that a significant number of patients have an unsatisfactory. This article discusses the multiple mechanisms of failure of primary intra-articular ACL reconstruction and provides the orthopaedic surgeon with a systematic approach to the evaluation and treatment of failed ACL reconstructions.
