The Impact of Physical Therapy After Lumbar Fusion Surgery.

STUDY DESIGN: Retrospective Cohort. OBJECTIVE: To determine if outcomes varied between patients based on physical therapy (PT) attendance after lumbar fusion surgery. SUMMARY OF BACKGROUND DATA: The literature has been mixed regarding the efficacy of postoperative PT to improve disability and back pain, as measured by patient-reported outcome measures. Given the prevalence of PT referrals and lack of high-quality evidence, there is a need for additional studies investigating the efficacy of PT after lumbar fusion surgery to aid in developing robust clinical guidelines. METHODS: We retrospectively identified patients receiving lumbar fusion surgery by current procedural terminology codes and separated them into 2 groups based on whether PT was prescribed. Electronic medical records were reviewed for patient and surgical characteristics, PT utilization, and surgical outcomes. Patient-reported outcome measures (PROMs) were identified and compared preoperatively, at 90 days postoperatively and one year postoperatively. RESULTS: The two groups had similar patient characteristics and comorbidities and demonstrated no significant differences between readmission, complication, and revision rates after surgery. Patients that attended PT had significantly more fused levels (1.41 ± 0.64 vs. 1.32 ± 0.54, P =0.027), longer operative durations (234 ± 96.4 vs. 215 ± 86.1 min, P =0.012), and longer postoperative hospital stays (3.35 ± 1.68 vs. 3.00 ± 1.49 days, P =0.004). All groups improved similarly by Oswestry Disability Index, short form-12 physical and mental health subsets, and back and leg pain by Visual Analog Scale at 90-day and 1-year follow-up. CONCLUSION: Our data suggest that physical therapy does not significantly impact PROMs after lumbar fusion surgery. Given the lack of data suggesting clear benefit of PT after lumbar fusion, surgeons should consider more strict criteria when recommending physical therapy to their patients after lumbar fusion surgery.

Comparison of Postoperative Opioid Use After Anterior Cervical Diskectomy and Fusion or Posterior Cervical Fusion.

INTRODUCTION: Posterior cervical fusion (PCF) and anterior cervical diskectomy and fusion (ACDF) are two main surgical management options for the treatment of cervical spondylotic myelopathy. Although ACDF is less invasive than PCF which should theoretically reduce postoperative pain, it is still unknown whether this leads to reduced opioid use. Our objective was to evaluate whether PCF increases postoperative opioid use compared with ACDF. METHODS: We retrospectively identified all patients undergoing 2-level to 4-level ACDF or PCF at a single center from 2017 to 2021. Our state's prescription drug-monitoring program was queried for filled opioid prescriptions using milligrams morphine equivalents (MMEs) up to 1 year postoperatively. In-hospital opioid use was collected from the electronic medical record. Bivariate statistics compared ACDF and PCF cohorts. Multivariate linear regression was done to assess independent predictors of in-hospital opioid use and short-term (0 to 30 days), subacute (30 to 90 days), and long-term (3 to 12 months) opioid prescriptions. RESULTS: We included 211 ACDF patients and 91 PCF patients. Patients undergoing PCF used more opioids during admission (126.7 vs. 51.0 MME, P < 0.001) and refilled more MMEs in the short-term (118.2 vs. 86.1, P = 0.001) but not subacute (33.6 vs. 19.7, P = 0.174) or long-term (85.6 vs. 47.8, P = 0.310) period. A similar percent of patients in both groups refilled at least one prescription after 90 days (39.6% vs. 33.2%, P = 0.287). PCF (ß = 56.7, P = 0.001) and 30-day preoperative MMEs (ß = 0.28, P = 0.041) were associated with greater in-hospital opioid requirements. PCF (ß = 26.7, P = 0.039), C5 nerve root irritation (ß = 51.4, P = 0.019), and a history of depression (ß = 40.9, P < 0.001) were independently associated with 30-day postoperative MMEs. CONCLUSIONS: PCF is initially more painful than ACDF but does not lead to persistent opioid use. Surgeons should optimize multimodal analgesia protocols to reduce long-term narcotic usage rather than change the surgical approach.Level of Evidence:III.

Work-related outcomes of revision rotator cuff repair for patients receiving workers' compensation.

BACKGROUND: Workers' compensation (WC) patients are susceptible to poorer outcomes following primary rotator cuff repair (RCR). Failure of structural healing can explain some poor results, and outcomes of revision RCR in this population are unknown. METHODS: A retrospective review was performed of individuals receiving WC who underwent arthroscopic revision RCR with or without dermal allograft augmentation at a single institution between January 2010 and April 2021. Preoperative magnetic resonance imaging (MRI) scans were assessed for rotator cuff tear characteristics, Sugaya classification, and Goutallier grade. Postoperative imaging was not routinely obtained unless for continued symptoms or reinjury. Primary outcome measures included return-to-work status, reoperation, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), and Single Assessment Numeric Evaluation (SANE) scores. RESULTS: Twenty-seven shoulders (25 patients) were included. The population was 84% male, with a mean age of 54 years; 67% were manual laborers, 11% sedentary workers, and 22% with a mixed profession. Average follow-up was 35.4 months. Fifteen patients (56%) returned to work at full-duty status. Six (22%) returned to work with permanent restrictions. Six (22%) were unable to return to work in any capacity. Thirty percent of all patients and 35% of manual laborers changed occupation following revision RCR. Mean time to return to work was 6.7 months. Overall, symptomatic rotator cuff retear was found in 13 patients (48%). Reoperation rate after revision RCR was 37% (10 cases). Among patients who did not undergo reoperation, mean ASES scores improved from 37.8 to 69.4 at final follow-up (P < .001). Mean SANE scores only improved marginally from 51.6 to 57.0 (P = .61). No statistically significant correlation was found between preoperative MRI findings and outcome measures. CONCLUSION: Workers' compensation patients demonstrated fair improvements in outcome scores after revision RCR. Although some patients are able to return to full duty, nearly half were either unable to return or returned with permanent restrictions. These data are helpful for surgeons when counseling patients about expectations and return to work after revision RCR in this challenging population.

Evaluating Outcomes of Spinopelvic Fixation for Patients Undergoing Long Segment Thoracolumbar Fusion with a Prior Total Hip Arthroplasty.

INTRODUCTION: Understanding the relationship between spinal fusion and its effects on relative spinopelvic alignment in patients with prior total hip arthroplasty (THA) is critical. However, limited data exist on the effects of long spinal fusions on hip alignment in patients with a prior THA. Our objective was to compare clinical outcomes and changes in hip alignment between patients undergoing long fusion to the sacrum versus to the pelvis in the setting of prior THA. METHODS: Patients with a prior THA who underwent elective thoracolumbar spinal fusion starting at L2 or above were retrospectively identified. Patients were placed into one of two groups: fusion to the sacrum or pelvis. Preoperative, six-month postoperative, one-year postoperative, and delta spinopelvic and acetabular measurements were measured from standing lumbar radiographs. RESULTS: A total of 112 patients (55 sacral fusions, 57 pelvic fusions) were included. Patients who underwent fusion to the pelvis experienced longer length of stay (LOS) (8.31 vs. 4.21, P < 0.001) and less frequent home discharges (30.8% vs. 61.9%, P = 0.010), but fewer spinal revisions (12.3% vs. 30.9%, P = 0.030). No difference was observed in hip dislocation rates (3.51% vs. 1.82%, P = 1.000) or hip revisions (5.26% vs. 3.64%, P = 1.000) based on fusion construct. Fusion to the sacrum alone was an independent predictor of an increased spine revision rate (odds ratio: 3.56, P = 0.023). Patients in the pelvic fusion group had lower baseline lumbar lordosis (LL) (29.2 vs. 42.9, P < 0.001), six-month postoperative LL (38.7 vs. 47.3, P = 0.038), and greater 1-year ∆ pelvic incidence-lumbar lordosis (-7.98 vs. 0.21, P = 0.032). CONCLUSION: Patients with prior THA undergoing long fusion to the pelvis experienced longer LOS, more surgical complications, and lower rate of spinal revisions. Patients with instrumentation to the pelvis had lower LL preoperatively with greater changes in LL and pelvic incidence-lumbar lordosis postoperatively. No differences were observed in acetabular positioning, hip dislocations, or THA revision rates between groups.

The Effect of Tranexamic Acid on Operative and Postoperative Blood Loss in Transforaminal Lumbar Interbody Fusions.

OBJECTIVE: The purpose of this retrospective cohort study was to evaluate the effect of tranexamic acid (TXA) on reducing perioperative blood loss and length of stay after transforaminal lumbar interbody fusion (TLIF). Spine surgery is associated with the potential for significant blood loss, and adequate hemostasis is essential to visualizing crucial structures during the approach and procedure. Although TXA use has been extensively studied in the pediatric and adult spinal deformity literature, there is a dearth of literature on its efficacy in reducing blood loss for patients who undergo 1- to 3-level TLIF. METHODS: All patients requiring 1- to 3-level TLIF who received a preoperative loading dose of TXA were grouped and compared with patients who didn't receive TXA. Demographic, surgical, and laboratory values were collected and analyzed. Continuous and categorical variables were analyzed with χ2, Kruskal-Wallis, or analysis of variance tests, depending on normality and data type. Multiple linear regressions were developed to determine independent predictors of the estimated blood loss (EBL), total blood loss, drain output, and length of stay. Statistical significance was set at P < 0.05. RESULTS: Patients who received preoperative TXA had more comorbidities (P = 0.006), longer surgery length (P < 0.001), and longer length of stay (P = 0.004). TXA was independently associated with a decreased day 0, 1, 2, and total drain output (P < 0.001, P = 0.001, P = 0.007, P < 0.001, respectively), but was not associated with a change in EBL, total blood loss, or length of stay. CONCLUSIONS: The application of preoperative TXA for patients undergoing 1- to 3-level TLIF reduced drain output in the first 2 postoperative days, but it did not affect hospital length of stay, total blood loss, or EBL.

The role of familial predisposition in imaging-confirmed atraumatic rotator cuff tears.

BACKGROUND: The etiology of atraumatic rotator cuff tears is not completely understood. Limited data suggest the role of genetic and familial predisposition in the etiology of rotator cuff tears. The purpose of this study was to assess whether there is an increased likelihood of rotator cuff tears in family members of patients with rotator cuff tears vs. those without tears. This would provide evidence for whether there is an association between familial predisposition and rotator cuff tearing. METHODS: Patients presenting to a shoulder clinic were recruited in this study. They provided information on personal medical history, shoulder symptoms, and family history of rotator cuff tears. The diagnosis of rotator cuff tears was based on imaging (magnetic resonance imaging or computed tomography arthrogram) confirmation of a structural defect in the rotator cuff. The association between family history of rotator cuff problems and the likelihood of an imaging-confirmed rotator cuff tear diagnosis was evaluated using multivariate logistic regression, adjusting for age, sex, race/ethnicity, cigarette smoking, hypertension, diabetes, and depression. RESULTS: In our cohort of 2335 patients, 52.6% (n = 1229) of patients had a rotator cuff tear. Among patients with tears, 17.9% (n = 220) of patients reported a family history of rotator cuff issues vs. 11.1% (n = 123) in patients without tears. A family history of rotator cuff problems was significantly associated with the diagnosis of an imaging-confirmed rotator cuff tear (odds ratio [OR] 2.24, 95% confidence interval [CI] 1.71, 2.95). Other confounding variables such as increasing age (OR 1.06, 95% CI 1.05, 1.07) and Hispanic race/ethnicity as compared to non-Hispanic white race/ethnicity (OR 1.48, 95% CI 1.07, 2.05) were significantly associated with rotator cuff tears. Sex, smoking, hypertension, diabetes, and depression were not significantly associated with rotator cuff tearing. CONCLUSION: Our study shows that individuals with rotator cuff tears were more than 2 times as likely to have a family member with a tear as compared to patients without tears. Increasing age and patients who identified as being of Hispanic ancestry were also significantly associated with higher odds of rotator cuff tears.
