Objective:Cervical myelopathy caused by ossification of the posterior longitudinal ligament (OPLL) is not uncommon among Asian ethnic groups. Despite reports comparing the pros and cons of anterior- and posterior-only approaches, the optimal management remains debatable. This study aimed to evaluate the outcomes of patients who underwent a combined anterior and posterior approach, simultaneous circumferential decompression and fixation, for cervical OPLL.Method:The study retrospectively reviewed patients with OPLL and who underwent circumferential decompression and fixation, combined anterior corpectomy and posterior laminectomy. The clinical outcomes were evaluated by the Visual Analog Scale of neck and arm pain, the Japanese Orthopedic Association scores, Neck Disability Index, and Nurick scores at each time-point of evaluation. Radiological evaluations included plain and dynamic radiographs and computed tomography for every patient within 2 years post-operation. Subgroup analyses were further performed between the groups, with and without intra-operative cerebrospinal fluid (CSF) leakage.Results:A total of 41 patients completed the follow-up for more than 2 years (mean = 39.8 months) and were analyzed. Continuous-type OPLL was the most common (44%), followed by segmental (27%), mixed (22%), and localized types (7%) in the cohort. Myelopathy and all other functional outcomes improved significantly at 2 years post-operation (all p < 0.05). There were 13 (32%) patients who had intra-operative CSF leakage. At 2 years post-operation, there were no differences in the demographics, functional outcomes, and complication rates between the CSF-leakage and no-leakage groups. The CSF-leakage group had more patients with continuous-type OPLL than the no-leakage group (77 vs. 29%, p = 0.004 < 0.05). During the follow-up, there was no secondary or revision surgery for pseudomeningocele, pseudarthrosis, or other surgery-related complications.Conclusions:Simultaneous circumferential decompression and fixation combine the surgical benefits of sufficient decompression by the posterior approach and direct decompression of OPLL by the anterior approach. It is an effective surgical option for patients with cervical myelopathy caused by OPLL, given that myelopathy unanimously improved without neurological complications in this study. The fusion rates were high, and reoperation rates were low. Despite higher rates of CSF leakage, there were no related long-term sequelae, and minimal wound complications.

Introduction. We performed a systematic review of the published literature to characterize patient demographic, surgical techniques, and functional outcomes to elucidate the complication and revision rates following isolated tibiotalar arthrodesis with anatomically contoured anterior plating. Methods. A comprehensive literature search was performed. Inclusion criteria were peer-reviewed studies in English, after 1990, at least 10 patients, and reporting clinical outcomes following contoured anterior plating and with follow-up of at least 80% and 1 year. Primary outcomes were fusion rate, time to fusion, return to activities, satisfaction, and functional outcome scores. Complication rates, reoperation, and revision were also extracted. Results. Eight primary studies with 164 patients met the inclusion criteria. The average sample size was 21 ± 10.0 patients and average age was 49.2 years with 61.6% male. Posttraumatic arthritis (49.4%) was the most common operative indication, followed by primary osteoarthrosis (18.9%). The average follow-up was 21.1 months. At this time, 97.6% of patients went on to uneventful union at a weighted average time of 18.7 weeks postoperatively. AOFAS scores improved significantly ( P < .05). 25% complication rate was reported with wound complication (7.9%) and hardware irritation (6.7%) most common. Overall, 21.3% of patients underwent reoperation; 4 for revision arthrodesis following nonunion. Conclusion. Isolated tibiotalar arthrodesis utilizing anatomically contoured anterior plating demonstrates excellent clinical and functional outcomes at short-term follow-up. Overall, 97.6% of patients went on to fusion and functional outcomes consistently improved following surgery. Furthermore, while one-quarter of patients experienced complications, wound complications were relatively uncommon and less than one-quarter of these required surgical intervention.

Cervical Stenotic Myelopathy

Object Two common causes of cervical myelopathy include degenerative stenosis and ossification of the posterior longitudinal ligament (OPLL). It has been postulated that patients with OPLL have more complications and worse outcomes than those with degenerative stenosis. The authors sought to compare the surgical results of laminoplasty in the treatment of cervical stenosis with myelopathy due to either degenerative changes or segmental OPLL. Methods The authors conducted a retrospective review of 40 instrumented laminoplasty cases performed at a single institution over a 4-year period to treat cervical myelopathy without kyphosis. Twelve of these patients had degenerative cervical stenotic myelopathy ([CSM]; degenerative group), and the remaining 28 had segmental OPLL (OPLL group). The 2 groups had statistically similar demographic characteristics and number of treated levels (mean 3.9 surgically treated levels; p > 0.05). The authors collected perioperative and follow-up data, including radiographic results. Results The overall clinical follow-up rate was 88%, and the mean clinical follow-up duration was 16.4 months. The mean radiographic follow-up rate was 83%, and the mean length of radiographic follow-up was 9.3 months. There were no significant differences in the estimated blood loss (EBL) or length of hospital stay (LOS) between the groups (p > 0.05). The mean EBL and LOS for the degenerative group were 206 ml and 3.7 days, respectively. The mean EBL and LOS for the OPLL group were 155 ml and 4 days, respectively. There was a statistically significant improvement of more than one grade in the Nurick score for both groups following surgery (p < 0.05). The Nurick score improvement was not statistically different between the groups (p > 0.05). The visual analog scale (VAS) neck pain scores were similar between groups pre- and postoperatively (p > 0.05). The complication rates were not statistically different between groups either (p > 0.05). Radiographically, both groups lost extension range of motion (ROM) following laminoplasty, but this change was not statistically significant (p > 0.05). Conclusions Patients with CSM due to either degenerative disease or segmental OPLL have similar perioperative results and neurological outcomes with laminoplasty. The VAS neck pain scores did not improve significantly with laminoplasty for either group. Laminoplasty may limit extension ROM.

Background. Fracture dislocation of the ankle represents a substantial injury to the bony and soft tissue structures of the ankle. There has been only limited reporting of functional outcome of ankle fracture-dislocations. This study aimed to compare functional outcome after open reduction internal fixation in ankle fractures with and without dislocation. Methods. A retrospective chart review of surgically treated ankle fractures over a 3- year period was performed. Demographic data, type of fracture, operative time and complications were recorded. Of 118 patients eligible for analysis, 33 (28%) sustained a fracture-dislocation. Mean patient age was 46.6 years; 62 patients, who had follow-up of at least 12 months, were analyzed for functional outcome assessed by the Foot and Ankle Outcome Score (FAOS). The median follow-up time was 37 months. Demographic variables and FAOS were compared between ankle fractures with and without dislocation. Results. The average age of patients sustaining fracture-dislocation was greater (53 vs 44 years, P = .017); a greater percentage were female (72.7% vs 51.8%, P = .039) and diabetic (24.2% vs 7.1%, P = .010). Wound complications were similar between both groups. FAOS was generally poorer in the fracture-dislocation group, although only the pain subscale demonstrated statistical significance (76 vs 92, P = .012). Conclusion. Ankle fracture-dislocation occurred more frequently in patients who were older, female, and diabetic. At a median of just > 3-year follow-up, functional outcomes in fracture-dislocations were generally poorer; the pain subscale of FAOS was worse in a statistically significant fashion.

Objective To review clinical outcomes of varicose vein patients treated with cyanoacrylate embolization and radiofrequency ablation at our institution. Methods A retrospective review of patients who underwent cyanoacrylate embolization and radiofrequency ablation during a three-year period. Patient records were reviewed to assess demographics, location and severity of disease, treatment details and outcome at short- and mid-term follow-ups. Outcome parameters included treatment success and complications. Results Between January 2014 and December 2016, 335 patients with 476 veins were treated with either cyanoacrylate embolization (n = 148) or radiofrequency ablation (n = 328) at the Vancouver General Hospital Vascular Surgery Vein Clinic. The average age of patients were 57 ± 1 years with the majority being female (78%) and an average BMI of 24.8 ± 0.5. CEAP classes were 2 (49%), 3 (26%), 4a (22%) and >4b (3%). Of the veins treated with cyanoacrylate embolization, the vein types were as follows: 76% were great saphenous vein, 16% were small saphenous vein, 5% were anterior accessory great saphenous vein and 1.4% were perforator veins. The vein types for radiofrequency ablation were 88%, 9%, 3% and 0%, respectively. The average amount of cyanoacrylate embolization delivered for great saphenous vein treatment was 1.8 ± 0.1 ml with a treatment length of 43 ± 1 cm. Subgroup comparison was done for great saphenous vein segments. Treatment success was 100% in cyanoacrylate embolization and 99% in radiofrequency ablation. Superficial phlebitis was the most common complication noted at mid-term follow-up in 5% of cyanoacrylate embolization and 16% of radiofrequency ablation treatments (P < 0.05). One patient in each group had asymptomatic proximal thrombus extension treated with anticoagulation for 2–3 weeks. Three superficial infections from glue clumps were noted in the cyanoacrylate embolization group requiring excision and drainage. Five patients in the radiofrequency ablation group had persistent numbness and one wound complications at the access site. Conclusion Cyanoacrylate embolization offers equivalent success rates with lower mid-term complication rates as radiofrequency ablation.

Category: Trauma Introduction/Purpose: Prompt reduction and stabilization of displaced ankle fractures is important to protect soft tissues, restore potential neurovascular deficits and prevent cartilage injury. Many of these injuries do eventually require surgical fixation. The purpose of this study is to determine whether the initial quality of ankle closed reduction based on radiographic criteria would affect outcomes such as ankle osteoarthritis and complications after surgery. Furthermore, we sought to develop a classification system for the quality of closed reduction that would be easy to use and provide interrater reliability. Methods: A retrospective analysis of patients who sustained isolated, closed ankle fractures with at least 3 months follow up postoperatively at two level 1 trauma centers was performed. Patient demographics and history, ankle fracture characteristics and reduction information as well as surgical outcomes and complications were collected. A grading classification for the quality of the initial closed reduction before surgery was developed based on standard AP or mortise and lateral ankle x-rays. The factors considered for rating the reduction included the degree of talar shift on the AP/mortise view, malleoli displacement, as well the relationship of a central plumb line to the center of the talar dome on the lateral x-ray. For ankle osteoarthritis, the Takakura classification was utilized. Three reviewers (1 resident, 2 attendings) independently reviewed and rated all imaging. Results: 161 patients were analyzed. 65% female, average age 50, average 4 days between injury and surgery, mean follow up of 12 months (3-58 months), and 17% wound complications. Psychiatric history was the single comorbidity significantly associated with complications (p=0.009). There was no difference in wound or infection complication rates based on initial closed reduction quality (p=0.17). Neither number nor quality of reductions correlated with increased osteoarthritis (p=0.19, 0.39 respectively). Worst graded reductions had shorter time to surgery, mean 1.4 vs 4.7 days for best reductions (p=0.03), suggesting a protective factor that may account for no association between reduction quality and wound complications. Interclass correlation coefficients for multiple observers showed very high consistency for grading of reduction quality based on the classification system (ICC >0.85, p<0.001). Conclusion: It is often emphasized that a displaced ankle fracture should be as perfectly reduced as possible, understandably for grossly dislocated ankle fracture dislocations potentially compromising skin and neurovascular structures. At the same time, this original study demonstrated contrary to common assumption that the initial quality of ankle closed reduction does not appear to affect the severity of ankle osteoarthritis or the rate of surgical complications. This study also developed a highly reproducible ankle reduction classification system. It opens the opportunity for future prospective application and analysis of this classification’s ultimate clinical utility.

Category: Ankle; Sports Introduction/Purpose: The surgical techniques for primary repair of acute Achilles tendon ruptures have evolved from large open incisions to mini-open and percutaneous techniques. Studies have demonstrated that lesser invasive surgical techniques may reduce the risk of post-operative wound complications. Knotless surgical repair of acute Achilles tendon ruptures can be performed through a mini-incision, but still permits a robust re-approximation of the tendon stumps and decreases suture burden through distal anchor fixation in the calcaneus. However, stress shielding and subsequent tendinosis of the distal tendon stump is a theoretical concern with this surgical technique. We hypothesize that our surgical technique allows for a durable repair through a minimally invasive approach, permitting a safe and accelerated rehabilitation protocol, excellent functional outcomes, and absence of distal stump tendinosis. Methods: A multicenter retrospective chart review was performed to identify all patients that underwent primary Achilles tendon repair using a knotless surgical technique with a minimum of one-year follow-up from three orthopedic foot and ankle surgeons’ practices. Exclusion criteria included: age <18, chronic Achilles tendon ruptures (>4 weeks), insertional Achilles tendon ruptures, revision Achilles surgery, peripheral neuropathy, and systemic inflammatory disease. All patients were contacted by phone and asked to return to the office for an MRI, clinical examination, and completion of functional outcome questionnaires. The primary outcome measure was the validated Achilles Tendon Total Rupture Score (ATRS). Secondary outcomes included the Visual Analog Score (VAS), postoperative complications, ankle range of motion, calf circumference, and single-heel rise. MRI was used to assess tendon continuity and healing, tendinosis, muscle atrophy, and bone marrow edema/stress fracture associated with anchor fixation in the calcaneus. MRI interpretation was performed by a single, blinded musculoskeletal radiologist. Results: Forty-three patients were identified with acute Achilles tendon ruptures. There were 36 patients (36/43, 84%) who underwent knotless Achilles tendon repair and agreed to participate in the study. The average time to clinical follow-up was 23.5 months (SD±16.3). The mean postoperative ATRS was 84.6 (SD±19.7). There was no significant difference in calf circumference (p=0.22), dorsiflexion (p=0.07), and plantarflexion (p=0.11) between the unaffected and surgical extremity at latest follow-up. One patient (1/36, 2.8%) experienced a re-rupture. There were no wound complications or neuritis. MRI was obtained in 26 patients (26/36, 72.2%) at an average of 17.5 months (SD±10.1). There were no MRI findings of distal stump tendinosis or calcaneal stress fractures. Thirty-two patients (32/36, 88.8%) returned to the same athletic activities one-year after surgery. Conclusion: There is paucity in the literature on functional outcomes following knotless Achilles tendon repair. In this multicenter study, we found that validated functional outcome scores and return to activity were similar to historical controls, with a low rate of surgical complications. MRI obtained in twenty-six patients (72.2%) at 17.5 months demonstrated an intact tendon without distal tendon stump stress shielding or calcaneal stress fracture. The knotless Achilles tendon repair is a unique surgical technique, minimizing suture burden and postoperative complications, while offering excellent functional outcomes and return to activity at two-year follow-up. The excellent clinical outcomes are corroborated by MRI.

OBJECTIVE Although posterior decompressive surgery is widely used to treat patients with cervical myelopathy and multilevel ossification of the posterior longitudinal ligament (OPLL), a poor outcome is anticipated if the sagittal alignment is kyphotic (or K-line negative). Accordingly, it is mandatory to perform anterior decompression and fusion in patients with cervical kyphosis. However, it can be difficult to perform anterior surgery because of the high risk of complications. This present report proposes a novel “greenstick fracture technique” to change the K-line from negative to positive in patients with cervical myelopathy, OPLL, and kyphotic deformity. METHODS Four patients with cervical myelopathy, continuous-type OPLL, and kyphotic sagittal alignment (who were K-line negative) were indicated for surgery. Posterior laminectomy and lateral mass screw insertions using a posterior approach were performed, followed by anterior surgery. Multilevel discectomy and thinning of the OPLL mass by bur drilling was performed, then an intentional greenstick fracture at each disc level was made to convert the cervical K-line from negative to positive. Finally, posterior instrumentation using a rod was carried out to maintain cervical lordosis. RESULTS MRI showed complete decompression of the cord by posterior migration in all cases, which had been caused by cervical lordosis. Restoration of neurological defects was confirmed at the 1-year follow-up assessment. No specific complications were identified that were associated with this technique. CONCLUSIONS A greenstick fracture technique may be effective and safe when applied to patients with cervical myelopathy, continuous-type OPLL, and kyphotic deformity (K-line negative). However, further studies with more cases will be required to reveal its generalizability and safety.

Object Adult degenerative scoliosis can be a cause of intractable pain, decreased mobility, and reduced quality of life. Surgical correction of this problem frequently leads to substantial clinical improvement, but advanced age, medical comorbidities, osteoporosis, and the rigidity of the spine result in high surgical complication rates. Minimally invasive surgery is being applied to this patient population in an effort to reduce the high complication rates associated with adult deformity surgery. Methods A retrospective study of 23 patients was undertaken to assess the clinical and radiographic results with minimally invasive surgery for adult thoracolumbar deformity surgery. All patients underwent a lateral interbody fusion followed by posterior percutaneous screw fixation and possible minimally invasive surgical transforaminal lumbar interbody fusion if fusion near the lumbosacral junction was necessary. A mean of 3.7 intersegmental levels were treated (range 2–7 levels). The mean follow-up was 13.4 months. Results The mean preoperative Cobb angle was 31.4°, and it was corrected to 11.5° at follow-up. The mean blood loss was 477 ml, and the operative time was 401 minutes. The mean visual analog scale score improvement for axial pain was 3.96. Clear evidence of fusion was seen on radiographs at 84 of 86 treated levels, with no interbody pseudarthroses. Complications included 2 returns to the operating room, one for CSF leakage and the other for hardware pullout. There were no wound infections, pneumonia, deep venous thrombosis, or new neurological deficits. However, of all patients, 30.4% experienced new thigh numbness, dysesthesias, pain, or weakness, and in one patient these new symptoms were persistent. Conclusions The minimally invasive surgical treatment of adult deformities is a promising method for reducing surgical morbidity. Numerous challenges exist, as the surgical technique does not yet allow for all correction maneuvers used in open surgery. However, as the techniques are advanced, the applicability of minimally invasive surgery for this population will likely be expanded and will afford the opportunity for reduced complications.

Study Design Retrospective cohort study. Objectives Laminoplasty (LAMP) is one of the effective methods to successfully achieve surgical decompression in patients with degenerative cervical myelopathy (DCM). However, little evidence exists regarding the perioperative complications in LAMP for patients with ossification of the longitudinal ligament (OPLL) compared with cervical spondylotic myelopathy (CSM). We aimed to investigate the perioperative complication rates and medical costs of DCM, including OPLL and CSM patients who underwent LAMP using a large national inpatient database. Methods This study identified patients who underwent LAMP for OPLL and CSM from 2010 to 2016 using the Japanese Diagnosis Procedure Combination database. We compared the incidence of perioperative complications (systemic and local), reoperation rates, medical costs during hospitalization, and mortality were between the OPLL and CSM groups after propensity score matching. Results This study included 22,714 patients (OPLL: 7485 patients, CSM: 15,229 patients). Consequently, 7169 pairs were matched. More perioperative systemic complications were detected in the OPLL group (one complication: 9.1% vs 7.7%; P = .002), especially for pneumonia (.5% vs .2%; P = .001) and dysphagia (.5% vs .2%; P = .004). The local complication rate was also higher in the OPLL group (paralysis: 1.1% vs .6%, P = .006; spinal fluid leakage: .4% vs .1%, P = .002). The hospitalization costs were approximately $2300 higher ($19,024 vs $16,770; P < .001) in the OPLL group. Conclusions More perioperative complications and higher medical costs were noted in patients with OPLL than in patients with CSM who underwent LAMP.

Background: Ossification of the posterior longitudinal ligament (OPLL) is a complex multi-factorial disease process having both metabolic and biomechanical factors. The objective of this study was to assess the surgical out come and post operative functional improvement in patients with cervical OPLL at a tertiary care centre.Methods: This prospective observational study included 35 patients undergoing surgery for cervical OPLL in the department of neurosurgery, Care hospitals Hyderabad from October 2015 to October 2016 with follow up at 3months and 6 months.Results: Total 35 patients who underwent surgery, majority (77.15%) were males and (22.85%) were female. The age of the patients was between 30 to 70 years. The most common type of OPLL was found to be segmental and mixed type. Nurick grade improved by 1.12 in anterior approach vs 0.66 in posterior approach. Recovery rates observed in anterior approach is 57.72% while in posterior surgical approach it is 48.87%. No complication was observed in this study.Conclusions: OPLL is more common in males as compared to females. The average age of presentation is sixth decade. Younger patients have better outcomes. The most common variant of OPLL is segmental.  The recovery rate achieved from anterior approach are better than those from the posterior approach. Improvement in NURICKS score is more in anterior surgical group than in posterior surgical group. No complications seen in this study. No mortality seen in this study.
