Mobilization of patients after spinal surgery for acute spinal cord injury

Effects of early mobilization within 48 hours of injury in patients with incomplete cervical spinal cord injury

OBJECTIVE

To investigate the effects of early mobilization within 48 h of injury on motor function and walking ability in patients with incomplete cervical spinal cord injury (SCI).

DESIGN

A retrospective observational study.

SETTING

Intensive care unit or high care unit of a university hospital emergency center.

PARTICIPANTS

Of 224 patients with SCI having American Spinal Injury Association impairment scale grades C and D, 158 consecutive patients hospitalized for at least 3 weeks after injury were included.

INTERVENTIONS

Patients were categorized into two groups: an early mobilization group in which patients were mobilized within 48 h of injury and a delayed mobilization group in which they were mobilized after 48 h of injury.

OUTCOME MEASURES

The upper extremity motor score (UEMS), lower extremity motor score (LEMS), and Walking Index for Spinal Cord Injury II (WISCI II) were compared using propensity score matching analysis.

RESULTS

Of the 158 patients who met the eligibility criteria, 32 were matched between the groups. There was a significant difference in the change in LEMS from the initial assessment to the assessment 2 weeks postoperatively in the early mobilization group (median 9 points vs. 3 points, p < 0.05). There were no significant differences in UEMS or WISCI II.

CONCLUSION

Early mobilization within 48 h may improve lower extremity motor function in patients with acute incomplete cervical SCI.

Factors associated with length of stay after single-level posterior thoracolumbar instrumented fusion primarily for degenerative spondylolisthesis

Background:

The postoperative length of stay (LOS) is an important prognostic indicator for patients undergoing instrumented spinal fusion surgery. Increased LOS can be associated with higher infection rates, higher incidence of venous thromboembolisms, and a greater frequency of hospital-acquired delirium. The day of surgery and early postoperative mobilization following single-level posterior thoracolumbar stabilizations may impact the LOS. In this study, we evaluated the effects of weekday (Monday–Thursday) versus weekend (Friday–Sunday) surgery and postoperative rehabilitation services on LOS following primarily transforaminal lumbar interbody fusion (TLIF) for degenerative spondylolisthesis (DS).

Methods:

In this single-institution retrospective chart review, we identified 198 adults who received a one-level thoracolumbar instrumented fusion through a posterior only approach (2017–2019). The majority of these patients underwent TLIF for DS. A zero truncated negative binomial model was used for predictors of the primary outcome of LOS (weekday of surgery, duration of operation, first or repeat surgery, and physical therapy/ occupational therapy [PT/OT] evaluation). Covariates were sex, age, and body mass index.

Results:

We found that operative duration, repeat surgery, and in-hospital PT/OT all significantly increased the LOS (P < 0.05). Furthermore, those undergoing weekday surgery (Monday–Thursday) had 1.29 times longer LOS than those on the weekend (Friday–Sunday), but this did not reach statistical significance (P = 0.09).

Conclusion:

In our patient sample, duration, repeat surgery, and in-hospital PT/OT increased the LOS following primarily TLIF for DS. The increased LOS in these cases is likely due to higher overall disease burden and case complexity. In addition, those patients with a greater likelihood of extended recovery and ongoing neurologic deficits are more likely to have PT/OT evaluations. Notably, LOS was not significantly impacted by the day of surgery at our institution.

Immediate weight bearing as tolerated (WBAT) correlates with a decreased length of stay post intramedullary fixation for subtrochanteric fractures: a multicenter retrospective cohort study

BACKGROUND

Subtrochanteric femur fractures associate with a relatively high complication rate and are traditionally treated operatively with a period of limited weight bearing. Transitioning from extramedullary to intramedullary implants, there are increasing biomechanical and clinical data to support early weight bearing. This multicenter retrospective study examines the effect of postoperative weight bearing as tolerated (WBAT) for subtrochanteric femur fractures. We hypothesize that WBAT will result in a decreased length of stay (LOS) without increasing the incidence of re-operation.

METHODS

This study assesses total LOS and postoperative LOS after intramedullary fixation for subtrochanteric fractures between postoperative weight bearing protocols across 6 level I trauma centers (n = 441). Analysis techniques consisted of multivariable linear regression and nonparametric comparative tests. Additional subanalyses were performed, targeting mechanism of injury (MOI), Winquist-Hansen fracture comminution, 20-year age strata, and injury severity score (ISS).

RESULTS

Total LOS was shorter in WBAT protocol within the overall sample (7.4 vs 9.7 days; p < 0.01). Rates of re-operation were similar between the two groups (10.6% vs 10.5%; p = 0.99). Stratified analysis identified patients between ages 41-80, WH comminution 2-3, high MOI, and ISS between 6-15 and 21-25 to demonstrate a significant reduction in LOS as a response to WBAT.

CONCLUSION

An immediate postoperative weight bearing as tolerated protocol in patients with subtrochanteric fractures reduced length of hospital stay with no significant difference in reoperation and complication rates. If no contraindication exists, immediate weight bearing as tolerated should be considered for patients with subtrochanteric femur fractures treated with statically locked intramedullary nails.

LEVEL OF EVIDENCE

Therapeutic Level III.

Enhanced recovery care versus traditional care following laminoplasty: A retrospective case-cohort study

Enhanced recovery after surgery (ERAS) has been shown to shorten length of hospital stay and reduce perioperative complications in many types of surgeries. However, there has been a paucity of research examining the application of ERAS to major spinal surgery. The current study was performed to compare complications and hospital stay after laminoplasty between an ERAS group and a traditional care group.The ERAS group included 114 patients who underwent laminoplasty managed with an ERAS protocol between January 2016 and June 2017. The traditional care group included 110 patients, who received traditional perioperative care between November 2014 and December 2015. Postoperative hospital stay (POPH), physiological function, postoperative visual analogue scale (VAS) pain score, and postoperative complications were compared between the 2 groups.The mean POPH was significantly shorter in the ERAS group than traditional care group (5.75 ± 2.46 vs. 7.67 ± 3.45 d, P < .001). ERAS protocol significantly promoted postoperative early food-taking (8.45 ± 2.94 h vs 21.64 ± 2.66 h, P < .001), reduced the first time of assisted walking (30.79 ± 14.45 vs. 65.24 ± 25.34 h, P < .001), postoperative time of indwelling urinary catheters (24.76 ± 12.34 vs. 53.61 ± 18.16 h, P < .001), and wound drainage catheters (43.92 ± 7.14 vs. 48.85 ± 10.10 h, P < .001), as compared with the traditional care group. Pain control was better in the ERAS group than traditional care group in terms of mean VAS score (2.72 ± 0.46 vs. 3.35 ± 0.46, P < .001) and mean maximum VAS score (3.76 ± 1.12 vs. 4.35 ± 1.15, P < .001) in 3 days after surgery. The morbidity rate was 21.05% (24 of 114 patients) in the ERAS group and 20.90% (23 of 110 patients) in the control group (P = .75).The ERAS protocol is both safe and feasible for patients undergoing laminoplasty, and can decrease the length of postoperative hospitalization without increasing the risk of complications.

A review article on the benefits of early mobilization following spinal surgery and other medical/surgical procedures

Background:

The impact of early mobilization on perioperative comorbidities and length of stay (LOS) has shown benefits in other medical/surgical subspecialties. However, few spinal series have specifically focused on the “pros” of early mobilization for spinal surgery, other than in acute spinal cord injury. Here we reviewed how early mobilization and other adjunctive measures reduced morbidity and LOS in both medical and/or surgical series, and focused on how their treatment strategies could be applied to spinal patients.

Methods:

We reviewed studies citing protocols for early mobilization of hospitalized patients (day of surgery, first postoperative day/other) in various subspecialties, and correlated these with patients’ perioperative morbidity and LOS. As anticipated, multiple comorbid factors (e.g. hypertension, high cholesterol, diabetes, hypothyroidism, obesity/elevated body mass index hypothyroidism, osteoporosis, chronic obstructive pulmonary disease, coronary artery disease and other factors) contribute to the risks and complications of immobilization for any medical/surgical patient, including those undergoing spinal procedures. Some studies additionally offered useful suggestions specific for spinal patients, including prehabilitation (e.g. rehabilitation that starts prior to surgery), preoperative and postoperative high protein supplements/drinks, better preoperative pain control, and early tracheostomy, while others cited more generalized recommendations.

Results:

In many studies, early mobilization protocols reduced the rate of complications/morbidity (e.g. respiratory decompensation/pneumonias, deep venous thrombosis/pulmonary embolism, urinary tract infections, sepsis or infection), along with the average LOS.

Conclusions:

A review of multiple medical/surgical protocols promoting early mobilization of hospitalized patients including those undergoing spinal surgery reduced morbidity and LOS.

Physical rehabilitation of the critically ill trauma patient in the ICU

OBJECTIVES

To 1) review the existing evidence for early mobilization of the critically ill patients in the ICU with polytrauma; 2) provide intensivists with an introduction to the biomechanics, physiology, and nomenclature of injuries; 3) summarize the evidence for early mobilization in each anatomic area; and 4) provide recommendations for the mobilization of these patients.

DATA SOURCES

A literature search of the MEDLINE and EMBASE databases for articles published in English between 1980 and 2011.

STUDY SELECTION

Studies pertaining to physical therapy and rehabilitation in trauma patients were selected. Articles were excluded if they dealt with pediatrics, geriatrics, burn injuries, isolated hand injuries, chronic (i.e., not acute) injuries, nontraumatic conditions, and pressure/decubitus ulcers, were in a language other than English, were published only in abstract form, were letters to the editor, were case reports, or were published prior to 1980.

DATA EXTRACTION

Reviewers extracted data and summarized results according to anatomical areas.

DATA SYNTHESIS

Of 1,411 titles and abstracts, 103 met inclusion criteria. We found no articles specifically addressing the rehabilitation of polytrauma patients in the ICU setting or patients with polytrauma in general. We summarized the articles addressing the role of mobilization for specific injuries and treatments. We used this evidence, in combination with biologic rationale and physician and surgeon experience and expertise, to summarize the important considerations when providing physical therapy to these patients in the ICU setting.

CONCLUSIONS

There is a paucity of evidence addressing the role of early mobilization of ICU patients with polytrauma and patients with polytrauma in general. Evidence for the beneficial role of early mobilization of specific injuries exists. Important considerations when applying a strategy of early physical therapy and mobilization to this distinctive patient group are summarized.

Pressure ulcer risk factors in persons with SCI: Part I: Acute and rehabilitation stages

BACKGROUND

Pressure ulcers (PUs) are a common complication following a spinal-cord injury (SCI). Good prevention requires identifying the individuals at risk for developing PUs. Risk assessment scales used nowadays were designed on pathophysiological concepts and are not SCI-specific. Recently, an epidemiological approach to PU risk factors has been proposed to design an SCI-specific assessment tool. The first results seem quite disappointing, probably because of the level of evidence of the risk factors used.

OBJECTIVE

To determine PU risk factors correlated to the patients with SCI, medical care management during the acute as well as in the rehabilitation and chronic stages. This first part focuses on identifying the risk factors during the acute and rehabilitation stages.

MATERIALS AND METHODS

Systematic review of the literature.

RESULTS

Six studies met our inclusion criteria. The risk factors during the acute stage of an SCI are essentially linked to care management and treatment modalities. There is insufficient evidence to make a recommendation on medical risk factors, except for low blood pressure on admission to the Emergency Room, with a moderate level of evidence. Regarding the rehabilitation stage, no study was deemed relevant.

DISCUSSION AND CONCLUSIONS

Additional observational studies are needed, for both the acute and rehabilitation stages, to improve this level of evidence. However, this systematic review unveiled the need for a carefully assessed t care management and the related practices, especially during the acute stage of an SCI.

Spinal fixation surgery for acute traumatic spinal cord injury

BACKGROUND

If the spine is unstable following traumatic spinal cord injury (SCI), surgical fusion and bracing may be necessary to obtain vertical stability and prevent re-injury of the spinal cord from repeated movement of the unstable bony elements. It has been suggested that this spinal fixation surgery may promote early rehabilitation and mobilisation.

OBJECTIVES

To answer the question: is there a difference in functional outcome and other commonly measured outcomes between people who have a spinal cord injury and have had spinal fixation surgery and those who have not?

SEARCH STRATEGY

The following databases were searched: AMED, CCTR, CINAHL, DARE, EMBASE, HEED, HMIC, MEDLINE, NRR, NHS EED. Searches were updated in May 2003 and MEDLINE was searched again in May 2007. The reference lists of retrieved articles were checked.

SELECTION CRITERIA

Randomised controlled trials and controlled trials that compared surgical spinal fixation, with or without decompression, to any other treatment, in patients with a traumatic SCI.

DATA COLLECTION AND ANALYSIS

Two reviewers independently selected studies. One reviewer assessed the quality of the studies and extracted data.

MAIN RESULTS

No randomised controlled trials or controlled trials were identified that compared surgical spinal fixation surgery to other treatments in patients with a traumatic SCI. All of the studies identified were retrospective observational studies and of poor quality.

AUTHORS' CONCLUSIONS

The current evidence does not enable conclusions to be drawn about the benefits or harms of spinal fixation surgery in patients with traumatic SCI. Well-designed, prospective experimental studies with appropriately matched controls are needed.

Spinal injuries centres (SICs) for acute traumatic spinal cord injury

BACKGROUND

The majority of complications in traumatic spinal cord injury (SCI) can occur in the first 24 hours and it has been suggested that spinal injury centres (SICs) may influence the pre-transfer care of people with SCI. The specialist SIC concept has been adopted in a number of high-income countries. However, even in such countries, a potentially significant number of people with SCI do not have the opportunity to access this system and are managed in a non-specialist environment.

OBJECTIVES

To answer the question: does immediate referral to an SIC result in a better outcome than delayed referral?

SEARCH STRATEGY

The following databases were searched: AMED, CCTR, CINAHL, DARE, EMBASE, HEED, HMIC, MEDLINE, NRR, NHS EED, and PsycLIT. Searches were updated in May 2003 and included the Cochrane Injuries Group Specialist Register. The reference lists of retrieved articles were checked.

SELECTION CRITERIA

Randomised controlled trials and controlled trials that compared immediate referral to an SIC with delayed referral in patients with a traumatic SCI.

DATA COLLECTION AND ANALYSIS

Two reviewers independently selected studies. One reviewer was to have assessed the quality of the studies and extracted data.

MAIN RESULTS

No randomised controlled trials or controlled trials were identified that compared immediate referral to an SIC with delayed referral in patients with a traumatic SCI. All of the studies identified were retrospective observational studies and of poor quality.

REVIEWERS' CONCLUSIONS

The current evidence does not enable conclusions to be drawn about the benefits or disadvantages of immediate referral versus late referral to SICs. Well-designed, prospective experimental studies with appropriately matched controls are needed.
