Posterior cervical spine arthrodesis with laminar screws: A report of two cases

Kazuo Nakanishi, Masato Tanaka, Yoshihisa Sugimoto, Toshifumi Ozaki

We performed fixation using laminar screws in 2 patients in whom lateral mass screws, pedicle screws or transarticular screws could not be inserted. One was a 56-year-old woman who had anterior atlantoaxial subluxation (AAS). When a guide wire was inserted using an imaging guide, the hole bled massively. We thought the re-insertion of a guide wire or screw would thus increase the risk of vascular injury, so we used laminar screws. The other case was an 18-year-old man who had a hangman fracture. Preoperative magnetic resonance angiography showed occlusion of the left vertebral artery. A laminar screw was inserted into the patent side (i.e., the right side of C2). Cervical pedicle screws are the most biomechanically stable screws. However, their use carries a high risk of neurovascular complications during screw insertion, because the cervical pedicle is small and is adjacent laterally to the vertebral artery, medially to the spinal cord, and vertically to the nerve roots. Lateral mass screws are also reported to involve a risk of neurovascular injuries. The laminar screw method was thus thought to be useful, since arterial injuries could thus be avoided and it could also be used as a salvage modality for the previous misinsertion.

BACKGROUND. Ewing sarcoma family of tumors (ESFT) of bone is extremely rare in Japan. The objectives of the Current study were to assess the clinical outcome and prognostic factors of patients with ESFT of bone in Japan and to compare them between Euro-American and Japanese populations.
METHODS. The authors conducted a retrospective analysis of 243 patients who were treated for ESFT of bone in Japan between 1981 and 2003. Local therapy was surgery in 35% of patients, surgery combined with radiotherapy in 40% of patients, radiotherapy alone in 22%, of patients, and no local treatment in 3% of patients. All but 3 patients received various regimens of multidrug chemotherapy.
RESULTS. The median patient age was 16 years. The primary disease sites were the trunk in 53% of patients and the extremities in 47% of patients. Forty-one patients had metastases at presentation. The median follow-up was 66 months. A univariate survival analysis demonstrated that patients who had metastases at presentation, primary site in the trunk, age >= 16 years, tumor size >= 10 cm, tumor that responded poorly to induction chemotherapy, and local treatment with radiotherapy alone had a significantly worse event-free survival (EFS). A multivariate analysis further verified that the former 3 factors were significant adverse prognostic factors. Of 201 patients with localized disease, 45 patients who received current chemotherapy regimens that included ifosfamide and etoposide had a significantly better 5-year EFS rate (67.6%) compared with other patients.
CONCLUSIONS. The clinical outcome of patients with localized ESFT of bone in Japan has improved markedly with the use of current chemotherapy regimens that include ifosfamide and etoposide and has become comparable to the Outcomes observed in other major series of Euro-American patients. The prognostic factors are also almost identical.

In successful knee arthroplasty, the femur and the tibia must be shaped to fit an artificial joint. The recent trend towards MIS (Minimally Invasive Surgery) to decrease the length of the required incision in the skin has increased surgical difficulty, since the open access area is small. The developed system consists of (1) a preplanning system providing a CAD function, (2) a multi-axis CAM system which avoids cutting the skin and the ligament, and keeps the cutting time within acceptable limits, and (3) a 7-axis machine tool that assures the safety of the patient and the surgeon, and enables MIS.

Minimally invasive surgery in orthopedic field is considered to be a challenging problem with a milling robot. One objective of this study is to minimize collision of the cutting tool with soft tissue. The authors have developed a robot with redundant axis to avoid the collision so far. Sorne important components are modeled based on physical requirements, and a geometric optimization approach based on the model has been also proposed to improve performance. In this paper, a protective mechanism to cover the non-working part of the cutting edge is proposed to avoid soft tissue damage. Hardware and software have been developed for this application and the effectiveness of this technique was evaluated with urethane bone.

腰椎変性すべり症に対する MIS-TLIF（Transforminal Lumbar Interbody Fusion）の短期成績

Posterior lumbar interbody fusion (PLIF) is considered to be a suitable operative procedure for degenerative spondylolisthesis. However, PLIF is known as a procedure with many side effects; among them these related to the extensive invasion of paravertebral muscles (PVM) are the most remarkable. In order to overcome this problem with the aim being the prompt recovery of patients, we have recently conducted the MIS-TLIF (minimally invasive surgery-transforaminal lumbar interbody fusion), which is associated with less PVM insult. The procedure enables patients to rise, walk, leave the hospital, and return to their job promptly. MIS-TLIF is the combination of PLIF procedure using a percutaneous pedicle screw and rod system, CD Horizon Sextant, a bilateral decompression and a transforaminal interbody fusion by hemi mini-open approach using microendoscope or microscope. We reported comparative short-term outcomes after MIS-TLIF and conventional PLIF. MIS-TLIF technique was associated with longer surgical procedure. However, bed rest length and admission were shorter when compared with the conventional PLIF procedure. Concerning efficiencies of JOA score about low back pain differences were absent. There was a reduction in the low back pain on day 3 after MIS-TLIF procedure comparing to the preoperative period when evaluated through the VAS score. The MIS-TLIF is a less invasive procedure, which is associated with a reduction of the low back pain in the postoperative period that contributes to shorten the length of bed rest and admission. MIS-TLIF technique is a less insulting procedure for the treatment of degenerative spondylolisthesis.

大腿骨頭回転骨切り術後の THA の検討

黒田崇之, 三谷茂, 遠藤裕介, 鉄永智紀, 尾﨑敏文, 浅海浩二

中・四整会誌 19 ( 1 ) 15 - 19 2007年

The purpose of this study was to examine clinical outcomes and operative pitfalls of six cases of total hip arthroplasty (THA) surgery after failed transtrochanteric rotational osteotomy (TRO) for avascular necrosis of the femoral head. Five were men and two were women. The average age of the patients at the time of conversion to THA was 40 years (range, 21-60 years). Postoperative Japanese Orthopaedic Association (JOA) scores showed very satisfactory improvement compared to preoperative scores (mean score 40.7/78.5 points, respectively). Compared to the primary THA procedure, the mean operation time of THA after the failed TRO was significantly longer and the average of blood loss was also significantly greater. Postoperative complications were observed in only one hip. The broach should be inserted carefully to avoid retroversion. It is important to completely remove the impingement of the osteophyte. Because in THA after TRO many pitfalls are existing, these points should be taken into preoperative and postoperative consideration.
