Percutaneous discectomy in athletes

Return to sports following discectomy: does a consensus exist?

INTRODUCTION

In the USA, lumbar discectomy is one of the most commonly performed spinal procedures. As certain sports are considered to be major risk factors for disc herniation, the question remains as to when highly active patients should return to their previous level of activity. This study aimed to analyze spine surgeons' opinions on when patients may return to activities following discectomy as well as their underlying rationale for their decision.

METHODS

A questionnaire was designed by five different fellowship-trained spine surgeons for the 168 members of the Spine Society of Australia. Questions on the surgeons experience, decision making, preferred surgical technique, the postoperative rehabilitation and the response to patient expectations were included.

RESULTS

In total, 83.9% of surgeons discuss the postoperative level of activity with their patients. Sport is considered as an important contributor for good functional outcome by 71.0% of surgeons. Surgeons recommend avoiding, often permanently, weightlifting (35.7%) of the time, rugby (21.4%), horseback riding (17.9%) as well as martial arts (14.3%) postoperatively even with previous training. The return to high levels of activity is considered as a major risk factor for disc herniation recurrence by 25.8% of surgeons. Return to high level of activity is typically recommended after 3 months by 48.4% of surgeons.

CONCLUSION

So far no consensus on the rehabilitation protocol and return to level of activity exists. Recommendations depend on personal experience as well as the individuals' training, and typically, a period of avoidance of sport for up to 3 months is recommended.

Return to Play After Symptomatic Lumbar Disc Herniation in Elite Athletes: A Systematic Review and Meta-analysis of Operative Versus Nonoperative Treatment

Context:

The prevalence of symptomatic lumbar disc herniation (LDH) in athletes can be as high as 75%. For elite athletes diagnosed with LDH, return to play (RTP) is a major concern, and thus comparing surgical with nonoperative care is essential to guide practitioners and athletes, not just in terms of recovery rates but also speed of recovery.

Objective:

The purpose of this systematic review is to provide an update on RTP outcomes for elite athletes after lumbar discectomy versus nonoperative treatment of LDHs.

Data Sources:

A search of the literature was conducted using 3 online databases (MEDLINE, EMBASE, and PubMed) to identify pertinent studies.

Study Selection:

Yielded studies were screened according to the inclusion criteria.

Study Design:

Systematic review with meta-analysis.

Level of Evidence:

Level 4.

Data Extraction:

Relevant data were extracted. A meta-analysis was performed comparing RTP rate for all comparative studies.

Results:

Twenty studies met the inclusion criteria and were included in this review. Overall, 663 out of 799 patients (83.0%) returned to play in the surgical group and 251 out of 308 patients (81.5%) returned to play in the nonoperative group. No statistically significant difference for RTP rate was found (odds ratio, 1.39; 95% CI, 0.58-3.34; P = 0.46; I2, 71%). The mean time to RTP for patients undergoing lumbar discectomy was 5.19 months (range 1.00-8.70 months), and 4.11 months (range 3.60-5.70 months) for those treated conservatively.

Conclusion:

There was no significant difference in RTP rate between athletes treated with operative or nonoperative management of LDHs, nor did operative management have a faster time to RTP. Athletes should consider the lack of difference in RTP rate in addition to the potential risks associated with spinal surgery when choosing a treatment option. Future randomized controlled trials are needed on this topic to allow for high-powered conclusions.

Early outcomes of transforaminal percutaneous endoscopic lumbar discectomy for high school athletes with herniated nucleus pulposus of the lumbar spine

There are no reports in the literature on the clinical outcomes of percutaneous endoscopic lumbar discectomy (PELD) for high school athletes suffering from herniated nucleus pulposus (HNP) of the lumbar spine. PELD is a minimally invasive surgical procedure that can be performed under local anesthesia via an 8-mm skin incision. This study examined the outcomes of transforaminal PELD in high school athletes suffering from HNP. Subjects were 18 patients [14 males and four females; mean age 17 (15-18) years] who underwent PELD at our institutions. The events in which the patients competed were baseball (n = 6), softball (n = 2), rugby (n = 2), basketball (n = 2), table tennis (n = 2), American football (n = 1), wrestling (n = 1), track and field (n = 1), and dance (n = 1). All patients underwent PELD under local anesthesia. Back pain was assessed using the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) and a visual analog scale (VAS) before and after surgery. Time to return to competitive sport, complications, and rate of recurrence of herniation were examined. All factors assessed by the JOABPEQ were significantly improved after surgery. VAS score was also improved after surgery. Time to return to competitive sport was 7 weeks on average. The rate of return to play was 94.4%. There were no complications, such as dural tear, exiting nerve root injury, or hematoma. One patient had recurrence of HNP. PELD is a promising minimally invasive and effective procedure for high school athletes with HNP.

Pediatric thoracolumbar spine surgery and return to athletics: a systematic review

OBJECTIVE

Spinal conditions and injuries in the pediatric population can necessitate surgical treatment. For many pediatric patients, a return to athletic activity after spinal surgery is a significant postoperative focus. However, there is a lack of standardized guidelines to determine criteria for safe return to play (RTP). To understand clinical criteria for patients to safely RTP, the authors conducted a systematic review of outcomes and the period of time before physicians recommend an RTP for pediatric patients undergoing spinal surgery.

METHODS

English-language publications were searched systematically in the PubMed electronic database, and a review was conducted in accordance with the PRISMA guidelines. Additional relevant studies found via a supplementary literature search were also included. Studies assessing return to athletic activity in a pediatric population after spinal surgery were included. Studies without an RTP, postsurgical activity outcomes, or surgical intervention were excluded.

RESULTS

A PubMed search identified 295 articles, with 29 included for the systematic review. In addition, 4 studies were included from a supplementary literature search. The majority of these studies were retrospective case series and cohort studies, and the remaining studies included questionnaire-based studies, prospective cohorts, and case-control studies. The most common spinal conditions or injuries included spondylolysis, and this was followed by adolescent idiopathic scoliosis. Overall, the most frequent recommendation for RTP for noncontact and contact sports was 6 months after surgery (range 1-12 months), and for collision sports it was 12 months after surgery. However, some physicians recommended never returning to collision sports after spinal intervention.

CONCLUSIONS

Most pediatric patients are able to return to some level of sports after spinal surgery. However, no standardized criteria have been proposed, and RTP recommendations vary according to the treating surgeon. In addition, limited data are published on the variation in timelines for RTP with regard to classifications of sports (noncontact, contact, and collision). Further analysis of specific spinal conditions and injuries with postoperative athletic recovery is needed.

Return to sport after open and microdiscectomy surgery versus conservative treatment for lumbar disc herniation: a systematic review with meta-analysis

BACKGROUND

Lumbar disc herniation has a prevalence of up to 58% in the athletic population. Lumbar discectomy is a common surgical procedure to alleviate pain and disability in athletes. We systematically reviewed the current clinical evidence regarding athlete return to sport (RTS) following lumbar discectomy compared to conservative treatment.

METHODS

A computer-assisted literature search of MEDLINE, CINAHL, Web of Science, PEDro, OVID and PubMed databases (from inception to August 2015) was utilised using keywords related to lumbar disc herniation and surgery. The design of this systematic review was developed using the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Methodological quality of individual studies was assessed using the Downs and Black scale (0-16 points).

RESULTS

The search strategy revealed 14 articles. Downs and Black quality scores were generally low with no articles in this review earning a high-quality rating, only 5 articles earning a moderate quality rating and 9 of the 14 articles earning a low-quality rating. The pooled RTS for surgical intervention of all included studies was 81% (95% CI 76% to 86%) with significant heterogeneity (I(2)=63.4%, p<0.001) although pooled estimates report only 59% RTS at same level. Pooled analysis showed no difference in RTS rate between surgical (84% (95% CI 77% to 90%)) and conservative intervention (76% (95% CI 56% to 92%); p=0.33).

CONCLUSIONS

Studies comparing surgical versus conservative treatment found no significant difference between groups regarding RTS. Not all athletes that RTS return at the level of participation they performed at prior to surgery. Owing to the heterogeneity and low methodological quality of included studies, rates of RTS cannot be accurately determined.

Microendoscopic discectomy in athletes

BACKGROUND

Management of lumbar disc herniation in athletes is challenging because a prolonged period of postoperative rehabilitation prevents the athlete from participating in sporting activity, resulting in loss of competitive form. No study reporting the clinical results of microendoscopic discectomy (MED) in athletes was identified in a literature search through PubMed, in spite of the relatively long history of this treatment. The objective of this study was to evaluate the efficacy of MED for athletes, focusing on their ability to quickly resume their sports activity.

METHODS

Twenty-five competitive athletes, who underwent MED participated in this study. The level of sporting activity patients were capable of achieving, and the time until complete return to competitive level were assessed. The Japanese Orthopaedic Association (JOA) score and short form 36 (SF-36) were also evaluated.

RESULTS

Two patients did not return to sporting activity for reasons unrelated to the lumbar diseases. Among the remaining 23 cases, 19 (82.6 %) successfully returned to their original levels of sporting activity. One patient (4.4 %) could not return to his pre-injury level of sporting activity because of residual pain. He changed his field from a high school sports team to a low-level sports society. The mean period until complete return to competition was 10.8 weeks (range 5-16 weeks). Three patients (13.0 %) could not resume sporting activity because of residual pain. The mean improvement rate of JOA score at final follow-up was 80.4 %. Significant improvements in SF-36 were observed in all subscales except in general health perceptions.

CONCLUSIONS

MED is a well-balanced technique which offers a high probability of return and an early return to the same level of sporting activity, both of which are optimal aims in treatment of athletes with lumbar disc herniation.

Return to play after conservative treatment in athletes with symptomatic lumbar disc herniation: a practice-based observational study

The purpose of the study was to confirm the short-term outcome of conservative treatment in terms of the ability to return to play and factors influencing return to play in athletes with symptomatic lumbar disc herniation. A total of 100 consecutive athletes (72 male and 28 female) who consulted our sports medicine clinic during the 16-year period between September 1993 and October 2009 because of severe low back pain and/or leg pain/numbness due to lumbar disc herniation were studied. The mean age of the subjects was 23 years. All of them were conservatively treated by being advised to discontinue their sporting activities with/without short-term medication. After the subjective symptoms had reduced by more than 80%, individual training was started in order to allow the athletes to return to play. Seventy-nine athletes (79.0%) returned to play at an average of 4.8 months (range 1–12 months) after the start of treatment and were able to sustain the activities for at least 6 months, the minimum duration of follow-up in the study. The outcome of the conservative treatment was not influenced by the intensity of the sporting activity. Multiple logistic regression analyses showed that the severity of the symptoms prior to the start of treatment was the factor influencing the ability of the athletes to return to play. The present study confirmed the satisfactory short-term outcome of conservative treatment in athletes with symptomatic lumbar disc herniation regarding return to play and revealed that subjective symptoms prior to the start of treatment appeared to be a key factor in return to play after conservative treatment.

Pediatric disk disease

Intervertebral disk herniation in pediatric patients is a rare but potentially disabling entity that is frequently difficult to diagnose. This article reviews the fundamentals of pediatric intervertebral disk herniation with the intention of presenting a rational and simple strategy for the evaluation and treatment of disk herniation in children, with specific emphasis on how it differs from adult disk disease in presentation, pathologic findings, and treatment options.

Short-term outcome of conservative treatment in athletes with symptomatic lumbar disc herniation

OBJECTIVE

The purpose of this study was to clarify the efficacy of conservative treatment in athletes with symptomatic lumbar disc herniation, especially in terms of their ability to return to their original sporting activities.

DESIGN

A total of 71 consecutive athletes (53 men and 18 women), who consulted our sports medicine clinic during the 10-yr period between September 1993 and October 2003 because of severe low back pain or leg pain/numbness due to lumbar disc herniation (confirmed on magnetic resonance images), were studied. The mean age of the subjects was 21 yrs. All of them were conservatively treated by advising them to discontinue their sporting activities, with or without short-term medication. After the subjective symptoms had reduced by >80%, individual training was started to allow the athletes to return to their original sporting activities.

RESULTS

A total of 56 athletes (78.9%) could return to their original sporting activities at an average of 4.7 mos (range, 1-12 mos) after the start of treatment and were able to sustain the activities for > or =6 mos, the minimum duration of follow-up in this study. The outcome of the conservative treatment was not influenced by the intensity of the sporting activity. Multiple logistic regression analyses showed that the only factor influencing the ability of the athletes to return to their original sporting activities was the severity of the symptoms before the start of treatment.

CONCLUSION

The results of this study suggest that the short-term outcome of conservative treatment in athletes with symptomatic lumbar disc herniation may be satisfactory in terms of control of the symptoms and the ability of the athletes to return to their original sporting activities and that the subjective symptoms before treatment may be a key factor influencing the success of the conservative management. Randomized controlled trials, or even comparative follow-up studies, are needed to confirm our results.

Return to play after lumbar spine conditions and surgeries

Low back pain in athletes can result from a wide variety of conditions. A detailed history and physical examination supplemented by appropriate imaging studies can lead to an accurate diagnosis. The majority of cases will be self-limiting and resolve within 6 weeks regardless of treatment, but it is important to be able to identify conditions that require specific treatment. The decision of when an athlete can return to active competition is determined by the specific condition, associated symptoms, and treatment provided. Most athletes can return to full unrestricted play after sufficient resolution of pain and restoration of range of motion. Athletes undergoing spinal fusion are typically restricted from full-contact sports.

Percutaneous nucleotomy in elite athletes

Percutaneous nucleotomy in elite athletes is considered a minimally invasive treatment of lumbar disc herniation. However, long-term effectiveness has not been established by careful follow-up studies. This article evaluates the outcome of percutaneous nucleotomy in elite athletes who have undergone the procedure. Thirty elite athletes with lumbar disc herniation who underwent percutaneous nucleotomy and had been followed for at least 2 years were compared with a matched group of 42 nonathletes. The outcome in athletes was worse than in nonathletes. Early return to vigorous sports activity in less than 3 months correlated with increased symptoms. Similarly, more extensive resection of disc material was associated with an unexpected rapid worsening of the outcome and the lower rate of return to preoperative sports. Patient selection and postoperative management of athletes and nonathletes undergoing percutaneous nucleotomy should be the same, and the procedure in athletes is probably not worthwhile if they do not obey postoperative management such as the timing of return to sports activity.

Treatment of lumbar disc herniation in the second decade of life

Lumbar disc herniation is rare in patients under the age of 20 years. In the department of orthopaedic surgery of the University Hospital of Frankfurt, 33 patients below the age of 20 with lumbar disc herniation were treated over a period of 10 years. Eighteen were managed conservatively and 15 surgically. The purpose of this study is to report on the long-term outcome of these patients and to compare the results of conservative and surgical treatment. We analysed information obtained from the medical records, and for the long-term follow-up we prepared a questionnaire. The questionnaire was composed of general questions about the patients' lifestyle and their ability to return to a normal life and activity after treatment, together with a request for them to score their pain level and remaining symptoms. We found that the longest duration of symptoms before diagnosis was 72 months, with a mean duration of 11.1 months. Low back pain and monoradicular sciatica were the main complaints, but findings of neurological deficits were rare. Lasegue's sign and tight hamstrings seemed to be strong diagnostic signs in this age group. On the day of discharge, 94% of patients reported excellent or good results. The outcomes after a mean follow-up period of 5.4 years were similar in both treatment groups. Almost all patients were able to attain a normal activity level and few reported restrictions on their daily life. Only 14% complained of permanent pain and 7% reported poor results regarding their activity capabilities. In conclusion, we believe that in all cases of lumbar disc herniation in the second decade of life, conservative treatment should be pursued as a mainstay of treatment. Only after a certain time, if conservative treatment is ineffective, should surgical treatment be considered.
