National Football League Head, Neck and Spine Committee's Concussion Diagnosis and Management Protocol: 2017-18 season.

One of the National Football League's (NFL) Head, Neck and Spine Committee's principal goals is to create a 'best practice' protocol for concussion diagnosis and management for its players. The science related to concussion diagnosis and management continues to evolve, thus the protocol has evolved contemporaneously. The Fifth International Conference on Concussion in Sport was held in Berlin in 2016, and guidelines for sports concussion diagnosis and management were revised and refined. The NFL Head, Neck and Spine Committee has synthesised the most recent empirical evidence for sports concussion diagnosis and management including the Berlin consensus statement and tailored it to the game played in the NFL. One of the goals of the Committee is to provide a standardised, reliable, efficient and evidence-based protocol for concussion diagnosis and management that can be applied in this professional sport during practice and game day. In this article, the end-of-season version of the 2017-18 NFL Concussion Diagnosis and Management Protocol is described along with its clinical rationale. Immediate actions for concussion programme enhancement and research are reviewed. It is the Committee's expectation that the protocol will undergo refinement and revision over time as the science and clinical practice related to concussion in sports crystallise.

Recent advances in the prevention and management of complications associated with routine lumbar spine surgery.

Lumbar spine surgery is often associated with complications in the perioperative and postoperative periods. Evidence-based literature in the prevention and management of adverse events, including surgical site infection, venous thromboembolism, and positioning-related complications, has advanced the understanding of the etiology of these complications and preventive measures. Cost-effective measures to reduce intraoperative bleeding can lead to a lower incidence of infection, disease transmission, and morbidity in the postoperative period. As the healthcare system receives additional scrutiny with value-based assessments, surgeons, hospitals, and administrators will need to make critical decisions to prevent and manage the complications of lumbar spine surgery.

Bone void fillers.

For this technology overview, the tools of evidence-based medicine were used to summarize information on the effectiveness and clinical outcomes related to the usage of bone void fillers- specifically, synthetic graft materials. Comprehensive literature searches were conducted to address five key questions, which the task force that prepared the report posed as follows. Question 1 addressed the use of synthetic bone void fillers alone. Question 2 was designed to determine whether synthetic bone void fillers could successfully serve as graft extenders and eliminate the need for iliac crest bone graft. Questions 3, 4, and 5 addressed the use of allografts as a comparison with synthetic fillers because clinical results with allografts are perceived as being much closer to autografts in these areas of the spine.

No S.C.A.R.E. Protocol: A Streamlined Safety Protocol.

INTRODUCTION: Despite the proven success of anterior cervical surgery (ACS) postoperative issues can arise, with retropharyngeal hematoma (RH) being one of the most feared. A recent USA Today article highlighted the failed management and subsequent death of patients developing RH after ACS. The article calls into question the safety of performing ACS in an outpatient setting. METHODS: We tested the knowledge of 20 healthcare professionals (4 surgeons, 16 ancillary providers) regarding ways to minimize the post-ACS complications. We used a multiple-choice and fill-in-the-blank test. We then developed a No S.C.A.R.E. safety protocol and after teaching the same professionals, re-administered the examination to assess improvement. RESULTS: We identified large gaps in knowledge between spine surgeons and other providers (92.3% versus 31.2%) on preintervention testing. Postintervention testing showed significant improvement in nonsurgeon scores (31.2% to 86.1%, P < 0.01). Improvement was also seen in provider confidence after completion of the education module. CONCLUSION: Previous studies demonstrate that the incidence of RH necessitating evacuation after ACS is extremely small (<1%). For rare complications, healthcare teams may benefit from educational modules and standardized protocols. After implementation of our No S.C.A.R.E. protocol, provider knowledge and confidence markedly improved. We recommend similar education modules and protocols be used at other institutions performing ACS.

The Variability of Lumbar Facet Joint Synovial Cyst Recurrence Requiring Revision Surgery After Decompression-only and Decompression/Fusion.

STUDY DESIGN: This is a retrospective study. OBJECTIVE: The objective of this study was to evaluate lumbar spine synovial cyst recurrence rates of decompression-alone versus decompression/fusion procedures. BACKGROUND: Improvements in imaging modalities allow for increased diagnosis and surgical treatment of symptomatic spinal juxtafacet synovial cysts. Conservative management may be used as a first-line management strategy, however rarely provides durable, effective relief of symptoms. Surgical treatment of spinal synovial cysts ranges from decompression and cyst excision to decompression with fusion procedures. Decompression procedures alone have a higher risk of recurrence of spinal synovial cysts. METHODS: We retrospectively reviewed 87 patients undergoing surgical treatment of lumbar spinal juxtafacet synovial cysts as a single institution over 20 years. Surgical treatment consisted of either decompression versus decompression/fusion procedures. Preoperative symptoms included back pain, radiculopathy, motor deficits, or sensory deficits. The incidence of recurrence of spinal synovial cysts at the same-site or differing sites was compared between 2 categories of surgical treatment. Revision surgical procedure rates were also evaluated. RESULTS: A total of 55 (63%) patients were treated with an index decompression-only procedure for the lumbar spinal synovial cyst compared with 32 (37%) patients treated with an index decompression and fusion procedure. Fifty-eight (68%) of the lumbar spinal cysts occurred at the L4-L5 level. There were 10 (11.5%) spinal synovial cyst recurrences in the decompression-only group, and 0 recurrences in the decompression/fusion group. Revision decompression procedures were performed in 4 of the 10 (4.6%) recurrences, and 6 of 10 (6.9%) recurrences had subsequent decompression and fusion surgery. The mean time to recurrence was 23.9±17.3 months. The mean length of follow-up was 65.1±48.6 months. Both recurrence and nonrecurrence cohorts had significant symptomatic improvement using Odom criteria. CONCLUSIONS: Decompression and cyst excision was the more common surgical treatment of lumbar spinal synovial cysts compared with decompression/fusion procedure in our study. The rate of synovial cyst recurrence and revision surgery in patients undergoing index decompression was relatively low and comparable to current literature. Symptomatic improvement of patients undergoing decompression versus decompression/fusion was similar in our study. Although the fusion may be required for the extent of pathology or coexisting instability, decompression and excision of spinal synovial cysts provide durable, effective treatment with a known, appropriate risk of recurrence and subsequent revision surgery.

Posterior Cervical Foraminotomy: Indications, Technique, and Outcomes.

Cervical radiculopathy presents with upper extremity pain, decreased sensation, and decreased strength caused by irritation of specific nerve root(s). After failure of conservative management, surgical options include anterior cervical decompression and fusion, disk arthroplasty, and posterior cervical foraminotomy. In this review, we discuss indications, techniques, and outcomes of posterior cervical laminoforaminotomy.

Return-to-play rates in National Football League linemen after treatment for lumbar disk herniation.

BACKGROUND: There is a paucity of evidence demonstrating clinical outcomes of high-end athletes sustaining a treatment for lumbar disk herniation. PURPOSE: To evaluate the ability of a National Football League lineman to return to play after lumbar diskectomy. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: National Football League offensive and defensive linemen diagnosed with a lumbar disk herniation were identified by previously published protocols using multiple sources of the public record. Demographic and statistical performance data were compiled for each player both before and after treatment. RESULTS: A total of 66 linemen (36 offensive and 30 defensive) met the inclusion criteria. Fifty-two were treated surgically, and 14 were treated nonsurgically. On average, this group had a body mass index of 35.4 and was 27.6 years old. Of those players treated surgically, 80.8% (42/52) successfully returned to play an average of 33 games over 3.0 years, with 63.5% (33/52) becoming starters after treatment. Conversely, only 28.6% (4/14) of linemen successfully returned to play after nonoperative intervention, which was significantly lower than those treated with a diskectomy (P < .05). Of the linemen in the surgical cohort, 13.5% (7/52) required revision decompression, and 85.7% (6/7) of these players successfully returned to play. CONCLUSION: National Football League linemen have high return-to-play rates after lumbar diskectomy. Furthermore, because those linemen requiring revision decompression successfully returned to play 85.7% of the time, this cohort should not be denied surgical treatment after recurrent problems. Although the data in our study suggest that National Football League linemen who are treated surgically have superior outcomes to those treated nonoperatively, because of the limitations with the methodology used in this study, further prospective studies are necessary to accurately compare treatment effects and to determine the long-term prognosis for these athletes after retirement.
