Retroperitoneal Extrapleural Approach for Corpectomy of the First Lumbar Vertebra : Technique and Outcome

Systematic Nursing Interventions Combined with Continuity of Care in Patients with a Spinal Fracture Complicated with a Spinal Cord Injury and Its Effect on Recovery and Satisfaction

Objective. The aim of this study is to examine the application value of systematic nursing interventions combined with continuity of care in cases with a spinal fracture complicated with a spinal cord injury and its effect on recovery and satisfaction. Methods. We identified ninety cases with a spinal fracture complicated with a spinal cord injury who were admitted to local hospital from May 2019 to May 2021 as research subjects and assigned them into an experimental group (systematic nursing combined with continuity of care, n = 45) and a control group (conventional nursing, n = 45) according to their admission order. The level of life of all groups between intervention was evaluated with reference to the Generic Quality of Life Inventory-74 (GQOLI-74) Rating Scale. The Hospital Anxiety and Depression (HAD) scale was used to assess the emotional status of patients before and after intervention. The complication rates, nursing outcomes, nursing satisfaction, and rehabilitation outcomes of all cases were calculated. Results. The GQOLI-74 score of the experimental group was higher than that of another group ( $P<0.05$ ). Lower HAD scores of experimental group were observed than that of another group ( $P<0.05$ ). The experimental group obtained remarkably higher nursing effective rates and higher nursing satisfaction than another group ( $P<0.05$ ). Rehabilitation outcome of the experimental group outperformed that another group ( $P<0.05$ ). Conclusion. The use of systematic nursing intervention combined with continuity of care for cases with spinal fracture complicated with a spinal cord injury can enhance the nursing effect, effectively relieve cases’ psychological pressure, improve patients’ level of life and nursing satisfaction, and contribute to the maintenance of a good nurse-patient relationship, which merits clinical promotion.

Technical nuances and approach-related morbidity of anterolateral and posterolateral lumbar corpectomy approaches-a systematic review of the literature

Purpose

Approaches for lumbar corpectomies can be roughly categorized into anterolateral (AL) and posterolateral (PL) approaches. It remains controversial to date whether one approach is superior to the other, and no comparative studies exist for the two approaches for lumbar corpectomies.

Methods

A systematic review of the literature was performed through a MEDLINE/PubMed search. Studies and case reports describing technique plus outcomes and possible complications were included. Thereafter, estimated blood loss (EBL), length of operation (LOO), utilized implants, neurological outcomes, complication rates, and reoperation rates were analyzed.

Results

A total of 64 articles reporting on 702 patients including 513 AL and 189 PL corpectomies were included in this paper. All patients in the PL group were instrumented via the same approach used for corpectomy, while in the AL group the majority (68.3%) of authors described the use of an additional approach for instrumentation. The EBL was higher in the AL group (1393 ± 1341 ml vs. 982 ± 567 ml). The LOO also was higher in the AL group (317 ± 178 min vs. 258 ± 93 min). The complication rate (20.5% vs. 29.1%, p = 0.048) and the revision rate (3.1% vs. 9.5%, p = 0.004) were higher in the PL group. Neurological improvement rates were 43.8% (AL) vs. 39.2% (PL), and deterioration was only noted in the AL group (6.0%), while 50.2% (AL) and 60.8% (PL) showed no change from initial presentation to the last follow-up.

Conclusion

While neurological outcomes of both approaches are comparable, the results of the present review demonstrated lower complication and revision rates in anterolateral corpectomies. Nevertheless, individual patient characteristics must be considered in decision-making.

Minimally Invasive Thoracolumbar Corpectomy and Percutaneous Pedicle Screw Fixation with Computer-Assisted Rod-Bending System in Single Lateral Position: Technical Note

BACKGROUND

Thoracolumbar corpectomy and percutaneous pedicle screw (PPS) fixation is becoming the standard method for correcting and stabilizing malalignment of spine, as is often seen in osteoporotic vertebral fracture. Nowadays, this procedure can be performed in a single lateral position with navigation. For an osteoporotic spine, accurate rod bending is necessary to prevent screw back-out. We describe a new technique using the spinal rod-bending system in a single lateral position.

METHODS

A 71-year-old woman presented with severe back pain and impending paraplegia secondary to L1 osteoporotic vertebral fracture. We performed minimally invasive L1 corpectomy with an expandable vertebral cage and short-segment PPS with computer-assisted rod bending in a single lateral position under navigation guidance.

RESULTS

The patient was successfully treated with surgery, and her low back pain improved. Her clinical outcomes improved; the Oswestry Disability Index went from 54% to 26%, and her low back pain visual analog scale score went from 78 mm to 19 mm at the 2-year final follow-up.

CONCLUSIONS

Minimally invasive surgery thoracolumbar corpectomy using a computer-assisted spinal rod-bending system is a valuable technique to reduce screw back-out for osteoporotic vertebrae. With this new technique, the rod bending becomes easy, even for long PPS fusion with the severe osteoporotic or deformity patient in a single lateral position.

Managing Incomplete and Complete Thoracolumbar Burst Fractures (AO Spine A3 and A4). Results from a Prospective Single-Center Study Comparing Posterior Percutaneous Instrumentation plus Mini-Open Anterolateral Fusion versus Single-Stage Posterior Instrumented Fusion

OBJECTIVE

The treatment strategy for thoracolumbar burst fractures is still debated. The aim of this study is to evaluate clinical and radiologic outcomes of a 2-stage strategy with immediate posterior percutaneous instrumentation and delayed anterolateral fusion (group A) versus a single-stage open posterior instrumented fusion (group B).

METHODS

Demographics and clinical and surgical data of patients operated for AO Spine A3 and A4 fractures were prospectively collected. Vertebral height and deformity were evaluated before and after surgery. Visual analog scale score for back pain, Oswestry Disability Index, and 12-Item Short Form Health Survey results for quality-of-life assessment were collected during follow-up.

RESULTS

Among the 110 patients enrolled, 66 were allocated to group A and 44 to group B; the most common fractured level was T12 (34%). Postoperative complications were higher in group B, especially the wound infection rate (18% vs. 3%), and pseudomeningocele (14% vs. 0%). The 2-stage approach allowed an average long-term gain of 15.8° at the local kyphosis of fractured vertebra and 5.8° at the regional level (Cobb angle), versus 15.4° and 5.5° in group B. At 2 years follow-up, both groups showed significant functional improvements; however, the visual analog scale and Oswestry Disability Index metrics seemed more favorable for group A patients (P < 0.0001 vs. P < 0.003). A complete fusion rate was obtained in 100% of group A vs. 65% of group B.

CONCLUSIONS

Our study indicates that percutaneous instrumentation and anterior fusion or an expandable cage lead to excellent long-term clinical and radiologic outcomes with a lower complication rate and higher fusion rate than those of open posterior approaches.
