Controversies in the Management of Cervical Spine Conditions in Elite Athletes

Return to sport and active military duty after cervical disc arthroplasty: A systematic review

Introduction

Cervical disc arthroplasty (CDA) has been established as an effective treatment for cervical disc degeneration or herniation in the general population. Return to sport (RTS) outcomes in athletes remain unclear.

Objective

The purpose of this review was to evaluate RTS following single-level, multi-level, or hybrid CDA, with additional return to activity context provided by return to duty (RTD) outcomes in active-duty military.

Methods

Medline, Embase, and Cochrane were searched through August 2022 for studies that reported RTS/RTD after CDA in athletic or active-duty populations. Data was extracted on the following topics: surgical failures/reoperations, surgical complications, RTS/RTD, and postoperative time to RTS/RTD.

Results

Thirteen papers covering 56 athletes and 323 active-duty members were included. Athletes were 59% male with a mean age of 39.8 years and active-duty members were 84% male with a mean age of 40.9 years. Only 1 of 151 cases required reoperation and only 6 instances of surgical complications were reported. Classified as return to general sporting activity, RTS was observed in 100% of patients (n = 51/51) after an average of 10.1 weeks to training and 30.5 weeks to competition. RTD was observed in 88% of patients (n = 268/304) after an average of 11.1 weeks. Average follow-up was 53.1 months for athletes and 13.4 months for the active-duty population.

Conclusion

CDA displays excellent RTS and RTD rates in physically demanding populations at rates superior or equivalent to alternative treatments. Surgeons should consider these findings when determining the optimal cervical disc treatment approach in active patients.

Management of Acute Subaxial Trauma and Spinal Cord Injury in Professional Collision Athletes

Sports-related acute cervical trauma and spinal cord injury (SCI) represent a rare but devastating potential complication of collision sport injuries. Currently, there is debate on appropriate management protocols and return-to-play guidelines in professional collision athletes following cervical trauma. While cervical muscle strains and sprains are among the most common injuries sustained by collision athletes, the life-changing effects of severe neurological sequelae (ie, quadriplegia and paraplegia) from fractures and SCIs require increased attention and care. Appropriate on-field management and subsequent transfer/workup at an experienced trauma/SCI center is necessary for optimal patient care, prevention of injury exacerbation, and improvement in outcomes. This review discusses the epidemiology, pathophysiology, clinical presentation, immediate/long-term management, and current return-to-play recommendations of athletes who suffer cervical trauma and SCI.

Off-label usage of RhBMP-2 in posterior cervical fusion is not associated with early increased complication rate and has similar clinical outcomes

BACKGROUND CONTEXT

Arthrodesis is important for the success of posterior cervical fusion (PCF), however, there exists limited data regarding the safety and efficacy of bone morphogenic protein (BMP) in PCF.

PURPOSE

The primary objective was to evaluate early postoperative complications associated with BMP in PCF and determine whether BMP leads to adverse early clinical outcomes. A secondary objective was to determine the optimal location for BMP sponge placement, within the facet joint (IF) or elsewhere, and the optimal dosage/level.

DESIGN

Retrospective, consecutive case-control study.

PATIENT SAMPLE

Seven hundred sixty-five patients who underwent PCF OUTCOME MEASURES: Patient-reported outcomes (PROs), complications, arthrodesis, optimum dose/level of BMP METHODS: Surgical data, including preoperative diagnosis, levels fused, type of bone graft, BMP dose (when used), and fusion technique were recorded. Complications were assessed by reviewing the medical record encompassing the first 6-weeks postoperative. These included medical, neurological, and wound-related complications and reoperation. Neurological complications were defined as any new weakness, radicular pain, or numbness. PROs were collected, including SF36, VAS, EQ-5D, and NDI scores. To determine the optimal dosage and location for BMP placement, a sub-analysis was performed.

RESULTS

There were no significant differences between the BMP and no BMP group with regards to wound complications, neurological complications, or reoperation. There were no differences in PROs between BMP and no BMP. Placement of BMP for IF and at a dose of 0.87 mg/level minimized wound-related complications. The BMP group had a higher fusion rate compared to the no BMP group (96% vs. 91%, p=.02) when assessed 1 year post-operatively.

CONCLUSION

BMP was not associated with a higher rate of early complications after PCF when the dose was minimized. Complications thought to be associated with BMP, such as compressive seroma, radiculitis, and wound-related complications were not seen at a higher rate. PROs at early follow-up were similar. Placement of BMP for IF and at lower doses than previously reported may minimize complications.
