    I included 24 cases (22 patients) with mental disorder in orthopedic surgery from April 2015 to Febrary 2017 in Kohnodai Hospital.

    I conducted the feature of surgical procedure, mental disorders, operatiosns, complications, the length of stay. Patients were male 9 and female 13. Mean age was 67.0±19.0 years old (17-93 years old).

    The rate of hospitalized deep venous thrombosis in patients with mental disorder has been reported from 10.0 % to 14.7%. In our hospital, the rate of it is 0.8% and it is relatively low compared to other reports.

    Clinical feartures of patients with mental disorder in orthopedic surgery in our hospital might be low complication.

    A 37-year-old man presented with a 4-year history of left hip joint and buttock pain. Radiographs, computed tomography, and bone scintigraphy revealed an osteochondroma on the postero-inferior aspect of the left femoral neck. It was thought that this lesion caused sciatic nerve pain such as the above hip and buttock pain.

    Surgical resection was performed. Postoperatively, the patient reported improvement in buttock pain. Pathologic findings revealed a definitive diagnosis of osteochondroma. Only five literatures reports about osteochondroma around the hip joint causing sciatic nerve pain previously. Therefore, our case of osteochondroma on the femoral neck with sciatic nerve pain was considered to be rare.

    Double endplates penetrating screw (DEPS) technique, which is a novel percutaneous pedicle screw (PPS) insertion technique for osteoporotic vertebral body fracture (OVF) in patients with diffuse idiopathic skeletal hyperostosis (DISH), was devised. The technique was applied to five cases, all of which were vertebral body fracture of thoracolumbar junction in patients with DISH. The DEPS technique is a modification of the penetrating S1 endplate screw (PES) technique by Matsukawa et al., and the insertion method is almost the same as the conventional PPS insertion technique. The screw is inserted upwards from outer caudal side of the pedicle toward the inner cranial side, penetrating the upper endplate of the target vertebral body and the lower endplate of the cranial vertebral body. Since this technique may reduce the number of fixation levels and implant failure in selected cases, we will start our study focusing on the biomechanical aspect of the technique.

    Case report: 14 years old, female. Dorsiflexion injury of left wrist jumping over the vaulting box in the class of physical education. Volar dislocation of distal radioulnar joint (DRUJ) and ulnar styloid process fracture was found in the X-ray photograph and computer tomography imaging. Tension band wiring for ulnar styloid process fracture and arthrodesis of DRUJ with Kirschner wire (K-wire) were performed. K-wire was removed and upper extremity was fixed with A-E cast in postoperative 2 weeks. The cast was removed 6 weeks after the operation and ROM exercise of the wrist was started. Implant removal was done 8 weeks after the surgery.
