    Assessment of Disability Related to Hip Dysplasia Using Objective Measures of Physical Performance.
    (Orthopaedic journal of sports medicine, 2020-02) Scott, Elizabeth J; Willey, Michael C; Mercado, Arthur; Davison, John; Wilken, Jason M

    Background

    Lower extremity physical performance measures (PPMs), which can objectively quantify functional ability, are an attractive adjuvant to patient-reported outcome (PRO) instruments. However, few tests have been validated for use in hip instability.

    Purpose

    To evaluate 4 different PPMs for their ability to differentiate between young adults with hip dysplasia indicated for treatment with periacetabular osteotomy (PAO) and asymptomatic controls and to test inter- and intratest reliability and relationship with popular hip PRO instruments.

    Study design

    Cohort study (diagnosis); Level of evidence, 2.

    Methods

    A total of 24 symptomatic patients aged 15 to 39 years (100% female) with hip dysplasia (lateral center-edge angle <25°) indicated for treatment with PAO completed the visual analog scale (VAS) for pain, Hip disability and Osteoarthritis Outcome (HOOS) Pain subscale, HOOS Short Version (HOOS PS), International Hip Outcome Tool Short Version (iHOT-12), modified Harris Hip Score (mHHS), Patient Reported Outcome Measurement Information System (PROMIS) physical function (PF) and pain interference (PI), and 4 physical function tests: (1) self-selected walking speed (SSWS), sit-to-stand 5 times (STS5), (3) 4-square step test (FSST), and (4) timed stair ascent (TSA). A further 21 young, asymptomatic adults aged 18 to 39 years (91% female) also underwent testing. Between-group comparisons were made with unpaired t test with Bonferroni-Holm correction. Inter- and intrarater reliability was assessed in 38 participants by repeating PPMs at a second visit and using 2 raters. Spearman rank correlation coefficients were used to determine associations between PPMs and PRO instruments.

    Results

    Significant differences between patients with hip dysplasia and controls were observed for all PRO instruments (HOOS Pain, 47.8 vs 99.2; HOOS PS, 61.9 vs 99.2; iHOT-12, 32.2 vs 99.2; mHHS, 54.5 vs 90.6; PROMIS PF, 41.4 vs 65.6; and PROMIS PI, 62.0 vs 39.1 [all P < .001]), and all PPMs (SSWS, 1.21 vs 1.53 m/s; STS5, 10.85 vs 5.95 s; FSST, 6.59 vs 4.03 s [all P < .001]; and TSA, 4.58 vs 3.29 s [P = .002]). All 4 PPMs demonstrated excellent intra- and intertest reliability (intraclass correlation coefficient, 0.83-0.99). STS5, FSST, and TSA were correlated highly (r > 0.5) with physical function PRO instruments, including PROMIS PF, mHHS, and iHOT-12.

    Conclusion

    Patients with symptomatic hip dysplasia demonstrated significant impairment on functional testing compared with asymptomatic controls, and performance measure testing demonstrated excellent test-retest reliability. Timed stair ascent and sit-to-stand testing in particular were correlated strongly with physical function PRO instruments. PPMs may be a viable and well-received adjuvant to PRO instrument administration for patients with nonarthritic hip conditions, and investigation of the ability of PPMs to assess surgical outcomes for hip dysplasia is warranted.

    Clinical Outcomes, Utilization, and Charges in Persons With Neck Pain Receiving Guideline Adherent Physical Therapy.
    (Eval Health Prof, 2016-12) Horn, Maggie E; Brennan, Gerard P; George, Steven Z; Harman, Jeffrey S; Bishop, Mark D
    In efforts to decrease practice variation, clinical practice guidelines for neck pain have been published. The purpose of this study was to determine the effect of receiving guideline adherent physical therapy (PT) on clinical outcomes, health care utilization, and charges for health care services in patients with neck pain. A retrospective review of 298 patients with neck pain receiving PT from 2008 to 2011 was performed. Clinical outcomes, utilization, and charges were compared between patients who received guideline adherent care and nonadherent care. Patients in the adherent care group experienced a lower percentage improvement in pain score compared to nonadherent care group (p = .01), but groups did not significantly differ on percentage improvement in disability (p = .32). However, patients receiving adherent care had an average 3.6 fewer PT visits (p < .001) and less charges for PT (p < .001). Additionally, patients receiving adherent care had 7.3 fewer visits to other health care providers (p < .001), one less prescription medication (p = .02) and 43% fewer diagnostic images (p = .02) but did not differ in their charges to other health care providers (p = .68) during the calendar year of undergoing PT. Although receiving guideline adherent care demonstrated positive effects on health care utilization and financial outcomes, there appears to be a trade-off with clinical outcomes.

    Incidence of revision surgery and patient-reported outcomes within 5 years of the index procedure for grade 1 spondylolisthesis: an analysis from the Quality Outcomes Database spondylolisthesis data.
    (Journal of neurosurgery. Spine, 2024-10) Birlingmair, Jacob; Carreon, Leah Y; Djurasovic, Mladen; Mummaneni, Praveen V; Asher, Anthony; Bisson, Erica F; Bydon, Mohamad; Chan, Andrew K; Chou, Dean; Coric, Domagoj; Foley, Kevin T; Fu, Kai-Ming; Haid, Regis; Knightly, John J; Le, Vivian P; Park, Paul; Potts, Eric A; Shaffrey, Christopher I; Shaffrey, Mark E; Slotkin, Jonathan R; Virk, Michael S; Wang, Michael Y; Glassman, Steven D

    Objective

    Some patients treated surgically for grade 1 spondylolisthesis require revision surgery. Outcomes after revision surgery are not well studied. The objective of this study was to determine how revision surgery impacts patient-reported outcomes (PROs) in patients undergoing decompression only or decompression and fusion (D+F) for grade 1 spondylolisthesis within 5 years of the index surgery.

    Methods

    Patients in the 12 highest Quality Outcomes Database (QOD) enrolling sites with a diagnosis of grade 1 spondylolisthesis were identified and the incidence of revision surgery between the decompression-only and D+F patients were compared. PROs were compared between cohorts requiring revision surgery versus a single index procedure.

    Results

    Of 608 patients enrolled, 409 had complete 5-year data available for this study. Eleven (13.3%) of 83 patients underwent revision in the decompression-only group as well as 32 (9.8%) of 326 in the D+F group. For the entire cohort, patients requiring revision had significantly worse PROs at 5 years: Oswestry Disability Index (ODI) 27.4 versus 19.4, p = 0.008; numeric rating scale for back pain (NRS-BP) 4.1 versus 3.0, p = 0.013; and NRS for leg pain (NRS-LP) 3.4 versus 2.1, p = 0.029. In the decompression-only group, the change in 5-year PROs was not impacted by revision status: ODI 31.9 versus 24.2, p = 0.287; NRS-BP 1.9 versus 2.9, p = 0.325; and NRS-LP 6.2 versus 3.7, p = 0.011. In the D+F group, the change in 5-year PROs was diminished if patients required revision: ODI 19.1 versus 29.1, p = 0.001; NRS-BP 3.0 versus 4.0, p = 0.170; and NRS-LP 2.3 versus 4.6, p = 0.001.

    Conclusions

    The most common reasons for reoperation within 5 years in the decompression-only group were repeat decompression and instability, whereas in the D+F group the most common reason was adjacent-segment disease. The need for revision resulted in modestly diminished benefit compared with patients with no revisions. These differences were greater in the fusion cohort compared with the decompression-only cohort. The mean PRO improvement still far exceeded minimal clinically important difference thresholds for all measures for patients who underwent a revision surgery.

    Racial disparities in inpatient clinical presentation, treatment, and outcomes in brain metastasis
    (Neuro-Oncology Practice, 2022) McCray, Edwin; Waguia, Romaric; de la Garza Ramos, Rafael; Price, Meghan J; Williamson, Theresa; Dalton, Tara; Sciubba, Daniel M; Yassari, Reza; Goodwin, Andrea N; Fecci, Peter; Johnson, Margaret O; Chaichana, Kaisorn; Goodwin, C Rory
    Abstract Background Few studies have assessed the impact of race on short-term patient outcomes in the brain metastasis population. The goal of this study is to evaluate the association of race with inpatient clinical presentation, treatment, in-hospital complications, and in-hospital mortality rates for patients with brain metastases (BM). Method Using data collected from the National Inpatient Sample between 2004 and 2014, we retrospectively identified adult patients with a primary diagnosis of BM. Outcomes included nonroutine discharge, prolonged length of stay (pLOS), in-hospital complications, and mortality. Results Minority (Black, Hispanic/other) patients were less likely to receive surgical intervention compared to White patients (odds ratio [OR] 0.70; 95% confidence interval [CI] 0.66–0.74, p &lt; 0.001; OR 0.88; 95% CI 0.84–0.93, p &lt; 0.001). Black patients were more likely to develop an in-hospital complication than White patients (OR 1.35, 95% CI 1.28–1.41, p &lt; 0.001). Additionally, minority patients were more likely to experience pLOS than White patients (OR 1.48; 95% CI 1.41–1.57, p &lt; 0.001; OR 1.34; 95% CI 1.27–1.42, p &lt; 0.001). Black patients were more likely to experience a nonroutine discharge (OR 1.25; 95% CI 1.19–1.31, p &lt; 0.001) and higher in-hospital mortality than White (OR 1.13; 95% CI 1.03–1.23, p = 0.008). Conclusion Our analysis demonstrated that race is associated with disparate short-term outcomes in patients with BM. More efforts are needed to address these disparities, provide equitable care, and allow for similar outcomes regardless of care.

    The impact of baseline cervical malalignment on the development of proximal junctional kyphosis following surgical correction of thoracolumbar adult spinal deformity.
    (Journal of neurosurgery. Spine, 2023-07) Passfall, Lara; Imbo, Bailey; Lafage, Virginie; Lafage, Renaud; Smith, Justin S; Line, Breton; Schoenfeld, Andrew J; Protopsaltis, Themistocles; Daniels, Alan H; Kebaish, Khaled M; Gum, Jeffrey L; Koller, Heiko; Hamilton, D Kojo; Hostin, Richard; Gupta, Munish; Anand, Neel; Ames, Christopher P; Hart, Robert; Burton, Douglas; Schwab, Frank J; Shaffrey, Christopher I; Klineberg, Eric O; Kim, Han Jo; Bess, Shay; Passias, Peter G

    Objective

    The objective of this study was to identify the effect of baseline cervical deformity (CD) on proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) in patients with adult spinal deformity (ASD).

    Methods

    This study was a retrospective analysis of a prospectively collected, multicenter database comprising ASD patients enrolled at 13 participating centers from 2009 to 2018. Included were ASD patients aged > 18 years with concurrent CD (C2-7 kyphosis < -15°, T1S minus cervical lordosis > 35°, C2-7 sagittal vertical axis > 4 cm, chin-brow vertical angle > 25°, McGregor's slope > 20°, or C2-T1 kyphosis > 15° across any three vertebrae) who underwent surgery. Patients were grouped according to four deformity classification schemes: Ames and Passias CD modifiers, sagittal morphotypes as described by Kim et al., and the head versus trunk balance system proposed by Mizutani et al. Mean comparison tests and multivariable binary logistic regression analyses were performed to assess the impact of these deformity classifications on PJK and PJF rates up to 3 years following surgery.

    Results

    A total of 712 patients with concurrent ASD and CD met the inclusion criteria (mean age 61.7 years, 71% female, mean BMI 28.2 kg/m2, and mean Charlson Comorbidity Index 1.90) and underwent surgery (mean number of levels fused 10.1, mean estimated blood loss 1542 mL, and mean operative time 365 minutes; 70% underwent osteotomy). By approach, 59% of the patients underwent a posterior-only approach and 41% underwent a combined approach. Overall, 277 patients (39.1%) had PJK by 1 year postoperatively, and an additional 189 patients (26.7%) developed PJK by 3 years postoperatively. Overall, 65 patients (9.2%) had PJF by 3 years postoperatively. Patients classified as having a cervicothoracic deformity morphotype had higher rates of early PJK than flat neck deformity and cervicothoracic deformity patients (p = 0.020). Compared with the head-balanced patients, trunk-balanced patients had higher rates of PJK and PJF (both p < 0.05). Examining Ames modifier severity showed that patients with moderate and severe deformity by the horizontal gaze modifier had higher rates of PJK (p < 0.001).

    Conclusions

    In patients with concurrent cervical and thoracolumbar deformities undergoing isolated thoracolumbar correction, the use of CD classifications allows for preoperative assessment of the potential for PJK and PJF that may aid in determining the correction of extending fusion levels.
