“…However, with focal OPLL this technique can be very effective. The anterior approach to OPLL decompression involves standard exposure as described by Smith-Robinson and others [20,23]. The OPLL itself can be resected completely, or otherwise thinned and released in what Yamaura et al [24] first described as the anterior decompression with floating (ADF).…”

Ossification of the Posterior Longitudinal Ligament: Surgical Approaches and Associated Complications

et al. 2019

Ossification of the posterior longitudinal ligament (OPLL) is a rare but potentially devastating cause of degenerative cervical myelopathy (DCM). Decompressive surgery is the standard of care for OPLL and can be achieved through anterior, posterior, or combined approaches to the cervical spine. Surgical correction of OPLL via any approach is associated with higher rates of complications and the presence of OPLL is considered a significant risk factor for perioperative complications in DCM surgeries. Potential complications include dural tear (DT) and subsequent cerebrospinal fluid leak, C5 palsy, hematoma, hardware failure, surgical site infections, and other neurological deficits. Anterior approaches are technically more demanding and associated with higher rates of DT but offer greater access to ventral OPLL pathology. Posterior approaches are associated with lower rates of complications but may allow for continued disease progression. Therefore, the decision to pursue either an anterior or posterior approach to surgical decompression may be critically influenced by complications associated with each procedure. The authors critically review anterior and posterior approaches to surgical decompression of OPLL with particular focus on the complications associated with each approach. We also review the recent work in developing new surgical treatments for OPLL that aim to reduce complication incidence.

Background:Aim of this study was to evaluate the effectiveness of various surgical interventions for the management of cervical spondylosis due to the ossification of posterior longitudinal ligament (OPLL).Methods:After a comprehensive literature search in electronic databases, studies were selected by following pre-determined eligibility criteria. Random effects meta-analyses were performed to estimate the effect sizes of various surgical approaches in improving Japanese Orthopedic Association (JOA) scores at latest follow-up and meta-regression analyses were carried out to examine the factors affecting the change in JOA score.Results:Twenty-three studies [1576 patients; 57.83 (95% confidence interval, 95% CI: 55.98–59.68] years of age; and 73 (70–76) % males; follow-up 55.4 ± 25.7 (range 12–170) months] were included in the meta-analysis. All surgical interventions significantly (P < .00001) improved JOA score. Anterior surgical approaches had an effect size of 4.80 [4.10–5.50] and posterior approaches with laminectomy and laminoplasty improved JOA score by 3.57 [2.39–4.75] and 3.99 [3.65–4.32], respectively. Improvement in JOA score was significantly inversely related to the preoperative JOA score (P < .00001). Surgical interventions did not significantly affect cervical lordosis at the latest follow-up.Conclusion:Surgical interventions for cervical spondylosis due to OPLL significantly improve JOA score as observed at the latest follow-up and this is found to be significantly inversely associated with preoperative JOA score.

Titanium Fiber Plates for Bone Tissue Repair

et al. 2017

Titanium plates are widely used in clinical settings because of their high bone affinity. However, owing to their high elastic modulus, these plates are not suitable for bone repair since their proximity to the bone surface for prolonged periods can cause stress shielding, leading to bone embrittlement. In contrast, titanium fiber plates prepared by molding titanium fibers into plates by simultaneously applying compression and shear stress at normal room temperature can have an elastic modulus similar to that of bone cortex, and stress shielding will not occur even when the plate lies flush against the bone's surface. Titanium fibers can form a porous structure suitable for cell adhesion and as a bone repair scaffold. A titanium fiber plate is combined with osteoblasts and shown that the titanium fiber plate is better able to facilitate bone tissue repair than the conventional titanium plate when implanted in rat bone defects. Capable of being used in close contact with bone for a long time, and even capable of promoting bone repair, titanium fiber plates have a wide range of applications, and are expected to make great contributions to clinical management of increasing bone diseases, including bone fracture repair and bone regenerative medicine.
