A minimally invasive surgical approach for the treatment of piriformis syndrome: a case series.

BACKGROUND: Piriformis syndrome accounts for approximately 6% of patients who present with sciatic pain. There are many treatment options ranging from physical therapy, to trigger point injections, to surgical intervention. We discuss a surgical method that represents a minimally invasive technique for the treatment of piriformis syndrome. METHODS: We describe a novel operative approach and technique for release of the piriformis muscle in the treatment of piriformis syndrome. Described are the preoperative planning, incision and approach, and technique for identifying and releasing the piriformis muscle. RESULTS: Three patients were treated for piriformis syndrome using the described technique. Each patient displayed successful relief of their symptoms immediately following the surgical procedure and at delayed follow-up. CONCLUSION: Early experience with our method of piriformis release suggests that it is well suited for the treatment of piriformis syndrome. The novel integration of pre-operative trigger point localization coupled with intraoperative neuromonitoring allows effective pain relief with minimal morbidity.

Impact of Clavicle Fractures on Return to Play and Performance Ratings in NFL Athletes.

OBJECTIVE: Clavicle fractures in the National Football League (NFL) have gained significant attention because of their impact on high profile athletes; however, little has been published on the overall impact of these injuries. This study sought to determine the time to return to play and quantitative impact on athletic performance after clavicle fractures in NFL athletes. DESIGN: Retrospective Cohort Study; Level of evidence, 3. SETTING: Retrospective cohort study of NFL athletes based on published injury reports and player statistics. PARTICIPANTS: This study consisted of 17 NFL athletes who sustained a clavicle fracture from 1998 to 2015 and returned to the field after the injury during the study period. Three athletes were excluded from performance analysis because of not playing for the entire season after injury. Control groups consisted of position-matched NFL athletes who competed in the 2013 NFL season without an identified clavicle injury. MAIN OUTCOME MEASURES: Median time to return to play after a clavicle fracture and the impact on player performance rating. RESULTS: Athletes returned to the competition after a median of 3.47 months after injury and missed a median of 8 games. There was no statistically significant impact on athletic performance after returning to play. CONCLUSION: Although clavicle fractures did have a significant impact on athletes because of lost playing time, there was no statistically significant difference in player performance after the injury when compared with a control group.

Surgical management of a complex case of Charcot arthropathy of the spine: a case report.

Introduction: The authors present a case of a 55-year-old male with T10 complete paraplegia diagnosed with Charcot arthropathy of the spine (CAS). Case presentation: He presented to an outside institution with vomiting and productive cough with subsequent computed tomography (CT) and MRI imaging revealing L5 osteomyelitis and a paraspinal abscess. Given the patient's inability to remain in good posture in his wheelchair he underwent a multilevel vertebrectomy and thoracolumbar fusion. Due to multiple co-morbidities, surgical recovery was complex, ultimately requiring revision circumferential fixation. Discussion: CAS is an uncommon, long-term complication of traumatic spinal cord injury (SCI). Surgical management is often complex and associated with significant complications. Currently, a consensus on CAS prevention, specific surgical fixation techniques and post-surgical nursing care management is lacking. In this case report we provide our experience in the management of a complex case of CAS to aid in decision making for future neurosurgeons who encounter this sequela of traumatic SCI.

Communication interventions to promote the public's awareness of antibiotics: a systematic review.

BACKGROUND: Inappropriate antibiotic use is implicated in antibiotic resistance and resultant morbidity and mortality. Overuse is particularly prevalent for outpatient respiratory infections, and perceived patient expectations likely contribute. Thus, various educational programs have been implemented to educate the public. METHODS: We systematically identified public-directed interventions to promote antibiotic awareness in the United States. PubMed, Google Scholar, Embase, CINAHL, and Scopus were queried for articles published from January 1996 through January 2016. Two investigators independently assessed titles and abstracts of retrieved articles for subsequent full-text review. References of selected articles and three review articles were likewise screened for inclusion. Identified educational interventions were coded for target audience, content, distribution site, communication method, and major outcomes. RESULTS: Our search yielded 1,106 articles; 34 met inclusion criteria. Due to overlap in interventions studied, 29 distinct educational interventions were identified. Messages were primarily delivered in outpatient clinics (N = 24, 83%) and community sites (N = 12, 41%). The majority included clinician education. Antibiotic prescription rates were assessed for 22 interventions (76%). Patient knowledge, attitudes, and beliefs (KAB) were assessed for 10 interventions (34%). Similar rates of success between antibiotic prescription rates and patient KAB were reported (73 and 70%, respectively). Patient interventions that did not include clinician education were successful to increase KAB but were not shown to decrease antibiotic prescribing. Three interventions targeted reductions in Streptococcus pneumoniae resistance; none were successful. CONCLUSIONS: Messaging programs varied in their designs, and many were multifaceted in their approach. These interventions can change patient perspectives regarding antibiotic use, though it is unclear if clinician education is also necessary to reduce antibiotic prescribing. Further investigations are needed to determine the relative influence of interventions focusing on patients and physicians and to determine whether these changes can influence rates of antibiotic resistance long-term.

The risk factors associated with delirium after lumbar spine surgery in elderly patients.

BACKGROUND: To prospectively explore the incidence and risk factors for postoperative delirium in elderly patients following lumbar spine surgery. METHODS: This prospective study enrolled 148 consecutive patients over the age of 65 who were scheduled to undergo spine surgery. Patients were screened for delirium using the short Confusion Assessment Method (CAM) postoperatively. Patient demographics and relevant medical information were collected. Logistic regression analysis was used to identify the risk factors associated with postoperative delirium. RESULTS: Eighty-three patients (56.1%) who underwent lumbar spine surgery (not coexisting with cervical or thoracic spine surgery) were enrolled in our study. Post-operative delirium was noted in 14.5% of patients over 65 years old. The presence of preoperative Parkinsonism was significantly higher in the delirium group (41.7% vs. 8.5%, P=0.002), as was a higher preoperative C-reactive protein (CRP) (7.0±15.2 vs. 1.3±2.3 mg/L, P=0.017) when compared with the non-delirium group. Of the risk factors, male sex [odds ratio (OR) =0.10, 95% confidence interval (CI): 0.01-0.66, P=0.017], Parkinsonism (OR =5.83, 95% CI: 1.03-32.89, P=0.046), and lower baseline MMSE score (OR =0.71, 95% CI: 0.52-0.97, P=0.032) were independently associated with postoperative delirium in elderly patients undergoing lumbar spine surgery. CONCLUSIONS: Post-operative delirium occurred in 14.5% of elderly patients who underwent lumbar spine surgery. Male sex, Parkinsonism, and lower baseline MMSE score were identified as independent risk factors for postoperative delirium in elderly patients following lumbar surgery.

A comparison of narcotic usage and length of post-operative hospital stay in open versus minimally invasive lumbar interbody fusion with percutaneous pedicle screws.

BACKGROUND: Instrumented lumbar fusion can be accomplished through open or minimally invasive techniques. The focus of this study was to compare perioperative narcotic usage and length of hospital stay between patients undergoing open versus minimally invasive spinal surgery (MISS). METHODS: A retrospective chart review was performed on 110 patients who underwent instrumented lumbar fusion over 2 years at our institution. These patients were divided into two groups: those that received open transforaminal interbody fusion (n=69), and those whose surgeries were performed minimally invasively with lateral lumbar transpsoas interbody fusion (LLIF) and percutaneous pedicle screws (n=41). Narcotic usage was recorded for both groups intra-operatively and post-operatively throughout their hospital stay. These values were standardized using an equianalgesia chart. RESULTS: Average narcotic usage post-operatively was significantly lower for the LLIF group relative to those who underwent open lumbar fusion (278.48 vs. 442.06 mg, P=0.03). The average length of post-operative hospital stay was significantly shorter for patients who underwent LLIF compared to those who had an open procedure (4.10 vs. 6.19 days, P=0.02). CONCLUSIONS: Patients who underwent minimally invasive surgery (MIS) LLIF had decreased overall use of opioids in the perioperative period and shorter hospital stays when compared to patients who underwent the open transforaminal interbody fusion approach. These findings support pre-existing literature in favor of LLIF MISS with regards to the above stated outcome measures. The long-term benefits of MISS with regards to narcotic usage in spine patients are not yet known.
