Metal-on-metal total hip arthroplasty (THA) is characterized by low wear and a wide range of motion. We performed metal-on-metal THA with limitations in young males with alcoholic avascular necrosis of the femoral head, and studied the short-term outcome of the procedure. Five patients were treated during the period from September 2007 to July 2008. All of the patients were males engaged in manual labor. The average age at the time of surgery was 39 years, and the average postoperative follow-up period was 5.2 months. The average period until return to work was 57 days, and no particular postoperative complications were observed. With regard to postoperative range of motion, more than 100 degrees of flexion was obtained. The average Japanese Orthopaedic Association hip score, which was 42 points before surgery, improved significantly to 93 points after surgery. In particular, pain was disappeared completely, and it was possible for the patients to return to heavy manual labor. As metal-on-metal THA might be involved with some problems, such as the metal ion concentration, its application to patients with renal dysfunction or gravida should be limited.

X-ray dark field imaging of human articular cartilage: Possible clinical application to orthopedic surgery

Toshiyuki Kunisada, Daisuke Shimao, Hiroshi Sugiyama, Ken Takeda, Toshifumi Ozaki, Masami Ando

EUROPEAN JOURNAL OF RADIOLOGY 68 ( 3 ) S18 - S21 2008年12月

記述言語：英語出版者・発行元：ELSEVIER IRELAND LTD

Despite its convenience and non-invasiveness on daily clinical use, standard X-ray radiography cannot show articular cartilage. We developed a novel type of X-ray dark field imaging (DFI), which forms images only by a refracted beam with very low background illumination. We examined a disarticulated distal femur and a shoulder joint with surrounding soft tissue and skin, both excised from a human cadaver at the BL20B2 synchrotron beamline at SPring-8. The field was 90 mm wide and 90 mm high. Articular cartilage of the disarticulated distal femur was obvious on DFI, but not on standard X-ray images. Furthermore, DFI allowed visualization in situ of articular cartilage of the shoulder while covered with soft tissue and skin. The gross appearance of the articular cartilage on the dissected section of the proximal humerus was identical to the cartilage shown on the DFI image. These results suggested that DFI could provide a clinically accurate method of assessing articular cartilage. Hence, DFI would be a useful imaging tool for diagnosing joint disease such as osteoarthritis. (C) 2008 Elsevier Ireland Ltd. All rights reserved.

The Minimally Invasive Plate Osteosynthesis (MIPO) Technique with a Locking Compression Plate for Femoral Lengthening

Hirosuke Endo, Koji Asaumi, Shigeru Mitani, Tomoyuki Noda, Hiroshi Minagawa, Tomonori Tetsunaga, Toshifumi Ozaki

ACTA MEDICA OKAYAMA 62 ( 5 ) 333 - 339 2008年10月

記述言語：英語出版者・発行元：OKAYAMA UNIV MED SCHOOL

A minimally invasive plate osteosynthesis technique using a locking compression plate (LCP) has been used widely in trauma cases. Its advantages are that the MIPO technique does not interfere with the fracture site and thus provides improved biological healing, and that the UP has excellent angular stability. Its use in bone lengthening, however, has not been established. In such cases, it is desirable to shorten the external skeletal fixation period as much as possible. Here, the MIPO technique using an UP was applied to femoral distraction osteogenesis in an attempt to shorten the external skeletal fixation period. For femoral lengthening, the MIPO technique was performed in 2 stages. Orthofix external fixators (Ortholix, England) were used to insert screws from the anterolateral side rather than from the lateral side of the femur for bone lengthening. When sufficient callus formation was detected postoperatively at the site of bone lengthening, and the absence of infection was ensured, limb draping was performed, including a whole external fixator, and then the MIPO technique was applied with an LCP.
In 3 cases (5 limbs), the average duration of external skeletal fixation was 134 days, the average external-fixation index was 24 days/cm, and the average consolidation index was 22 days/cm. The MIPO technique using an LCP made it possible to shorten the external skeletal fixation-wearing period in femoral lengthening.

Spinal cord herniation into pseudomeningocele after traumatic nerve root avulsion: case report and review of the literature

EUROPEAN SPINE JOURNAL 17 ( Suppl 2 ) S263 - S266 2008年9月

記述言語：英語掲載種別：書評論文，書評，文献紹介等出版者・発行元：SPRINGER

We present an extremely rare case of traumatic spinal cord herniation due to a brachial plexus avulsion injury and provide a review of the literature of spinal cord herniation. Spinal cord herniation is an uncommon condition that can occur spontaneously or as a result of surgery or trauma. This condition often presents with symptoms and signs as Brown-Sequard syndrome. Traumatic pseudomeningoceles after a brachial plexus avulsion injury have been reported. But transdural herniation of the spinal cord into this pseudomeningocele is an extremely rare and poorly documented condition. There is only two reports of this condition in a thoracic case. The authors report the case of a 22-year-old man presented with a 2-year history of quadriplegia. He was involved in a motorcycle accident, 3 years prior to his presentation. Four years after the initial right brachial plexus injury, he was not able to walk independently. Magnetic resonance imaging (MRI) and computerized tomography (CT) myelography revealed a lateral pseudomeningocele arising from the right C6-7 and C7-T1 intervetebral foramen and cervical spinal cord herniation into this pseudomeningocele. The patient underwent primary closure of pseudomeningocele to prevent spinal cord reherniation. He can walk with cane and use left arm unrestrictedly at the 2-year follow-up examination. Spinal cord herniation following traumatic nerve root avulsion is extremely rare but it should be considered in the differential diagnosis of patients presenting with delayed myelopathy or Brown-Sequard syndrome.

Disease-specific screening for deep venous thrombosis and pulmonary thromboembolism using plasma D-dimer values after total knee arthroplasty

Teruhito Yoshitaka, Nobuhiro Abe, Hiroshi Minagawa, Hirokazu Date, Yoshimasa Sakoma, Keiichiro Nishida, Toshifumi Ozaki

We prospectively evaluated the disease-specific features of the early postoperative plasma D-dimer value and the relationship with deep venous thrombosis and/or pulmonary thromboembolism (DVT/PE) in 95 patients following total knee arthroplasty. Patients in whom DVT/PE was highly suspected were diagnosed by high-resolution multi-detector row computed tomography scanning (MDCT). Forty-nine knees in 46 patients with rheumatoid arthritis (RA, 24 knees) or osteoarthritis (OA, 25 knees) were finally recruited. DVT/PE was detected in 28 (57.1%) of the 49 cases examined by diagnostic MDCT: 12 (50.0%) of the 24 cases of RA, and 16 (64.0%) of the 25 cases of OA. Of these, PE was found in 11 cases (39.2%), but none of them showed clinical symptomatic signs of dyspnea or chest pain. In both RA and OA cases, there were statistically significant differences in the D-dimer value on postoperative day 3 (P = 0.027) and after day 28 (P = 0.037) between the groups with and without DVT/PE. In OA cases, there were significant differences between the two groups on postoperative days 1 (P = 0.034), 3 (P = 0.020), 5 (P = 0.005), and 7 (P = 0.045), respectively. At the baseline, perioperative D-dimer levels in the RA group without DVT/PE were higher than in the OA group. However, multivariate logistic regression analysis showed that RA was not a significant risk factor of DVT/PE in comparison with OA. In conclusion, individual evaluation of the D-dimer level between RA and OA should provide a more precise predictive indicator of early postoperative DVT/PE.
