The true efficacy of laminoplasty for maintaining spinal alignment, stability, and flexibility, however, remains to be proven. The authors have developed a new method, myoarchitectonic spinolaminoplasty (MSLP), which preserves all of the nuchal muscles and reconstitutes all of the musculoskeletal couplings to the posterior elements of the vertebrae. The details of this technique are described, and the efficacy of the technique in conserving muscle volume, alignment, and motion, as well as in preventing postoperative musculoskeletal discomfort, is assessed.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>The authors' previous midline-splitting laminoplasty procedure, which utilized a hydroxyapatite (HA) implant as a substitute for the spinous process, was improved. Detachment of the muscles is avoided with this new technique by cutting inside the spinous process. The bone\u2013muscle flaps are affixed to the HA spinous process. Radiographs, computed tomography scans, and neurological evaluations obtained at the 1-year follow-up in the groups of consecutive patients assessed immediately prior to and after the modification of the previous technique (the control and the MSLP groups, respectively) were analyzed and compared.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>The HA bone constructs became integrated due to osteoconduction. The cross-sectional area of the semispinalis capitis, semispinalis cervicis, and multifidus muscles remained significantly larger in the MSLP group. Slight attenuation in lordosis was observed in the control group, but was prevented in the MSLP group. Range of motion was somewhat restricted in the MSLP group, but the incidence of neck pain and shoulder strain was significantly reduced.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>The new MSLP method was effective in preserving the volume and functions of the nuchal musculature and helping to minimize postoperative musculoskeletal complaints.<\/jats:p><\/jats:sec>","DOI":"10.3171\/spi-07\/09\/293","type":"journal-article","created":{"date-parts":[[2008,1,24]],"date-time":"2008-01-24T12:23:52Z","timestamp":1201177432000},"page":"293-304","source":"Crossref","is-referenced-by-count":79,"title":["Myoarchitectonic spinolaminoplasty: efficacy in reconstituting the cervical musculature and preserving biomechanical function"],"prefix":"10.3171","volume":"7","author":[{"given":"Phyo","family":"Kim","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidetoshi","family":"Murata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryu","family":"Kurokawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiyuki","family":"Takaishi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keizo","family":"Asakuno","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiki","family":"Kawamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-0070293","series-title":"Arch Orthop Trauma Surg","doi-asserted-by":"publisher","first-page":"203","DOI":"10.1007\/BF00434554","article-title":"Atrophy of the nuchal muscle and change in cervical curvature after expansive open-door laminoplasty","volume":"115","author":"Fujimura","year":"1996"},{"key":"b2-0070293","series-title":"Spine","doi-asserted-by":"publisher","first-page":"870","DOI":"10.1097\/00007632-198807000-00032","article-title":"Operative procedure and results of expansive open-door laminoplasty","volume":"13","author":"Hirabayashi","year":"1988"},{"key":"b3-0070293","series-title":"Spine","doi-asserted-by":"publisher","first-page":"693","DOI":"10.1097\/00007632-198310000-00003","article-title":"Expansive open-door laminoplasty for cervical spinal stenotic myelopathy","volume":"8","author":"Hirabayashi","year":"1983"},{"key":"b4-0070293","series-title":"J Neurosurg Spine","doi-asserted-by":"publisher","first-page":"29","DOI":"10.3171\/spi.2005.3.1.0029","article-title":"En bloc laminoplasty without dissection of paraspinal muscles","volume":"3","author":"Hosono","year":"2005"},{"key":"b5-0070293","series-title":"Spine","doi-asserted-by":"publisher","first-page":"1969","DOI":"10.1097\/00007632-199609010-00005","article-title":"Neck and shoulder pain after laminoplasty.
