La Frailty as a predictor index in spine surgery

Rev Fac Cien Med Univ Nac Cordoba 2021 03 12;78(1):9-16. Epub 2021 Mar 12.

Hospita Italiano de Buenos Aires.

Introduction: Frailty is a term used to quantify the physiological age of patients. Higher levels of frailty correlate with higher complications and mortality rates after different surgical procedures. The objective of this work is to evaluate the relationship between frailty and the complications and mortality rates after elective spinal surgeries within 90 days.

Material And Methods: A retrospective observational analytical study of patients older than 18 years with elective spine surgery was performed. The following variables were analyzed differentially according to their Modified Frailty Index (mFI) with a cut-off point of 0,18: age, sex, body mass index, ASA score, details of the procedures, length of stay, complications, unscheduled rehospitalizations, reoperations, and mortality within 90 postoperative days.

Results: 257 patients were included. Within the 30 complications, 16 occurred in the non-frail group (8%) and 14 in frail patients (24.5%), (p = 0.02). Six complications were infectious in the group of frail patients (10.5%) and 4 in the non-frail patients (2%), (p = 0.009). No significant differences were detected regarding the duration of surgeries, the length of stay or the reoperations, re-hospitalizations or mortality rates.

Conclusion: Patients with a modified Frailty Index ≥0,18 who underwent elective spine surgery were 3 times more likely to present complications, particularly, infectious ones.

Chylothorax, a rare complication after anterior lumbar interbody fusion. Case report

Rev Fac Cien Med Univ Nac Cordoba 2020 12 21;77(4):381-384. Epub 2020 Dec 21.

Hospital Italiano de Buenos Aires.

Introduction: Chylous leakage into the retroperitoneum is a rare complication after spinal surgery using an anterior retroperitoneal approach. Chylothorax is the presence of lymphatic fluid in the pleural cavity and it is even less frequent during these surgeries. The aim of this work is to report the first case of isolated left chylothorax after a retroperitoneal Left Oblique Lumbar Interbody Fusion in supine position in an adult female patient.

Case: A female 30-years-old patient underwent L4-L5 anterior interbody fusion. Four days after the intervention she was diagnosed with isolated left chylothorax that was drained and treated conservatively with good outcomes.

Conclusion: Chylothorax is an extremely rare complication after anterior lumbar spine procedures, and it is usually secondary to a chyloretroperitoneum. We present a unique case of isolated chylothorax after anterior retroperitoneal lumbar approach successfully treated in a conservative manner. Key Words chylothorax; spine; lumbosacral region; arthrodesis.

Development of a New Therapy-Oriented Classification of Intervertebral Vacuum Phenomenon With Evaluation of Intra- and Interobserver Reliabilities.

Global Spine J 2021 May 13;11(4):480-487. Epub 2020 Mar 13.

Institute of Orthopedics "Carlos E. Ottolenghi" 37533Hospital Italiano de Buenos Aires, Buenos Aires, Argentina.

Study Design: Diagnostic study, level of evidence III.

Objectives: Low back pain is a common cause of disability among elderly patients. Percutaneous discoplasty has been developed as a tool to treat degenerative disease when conservative management is not successful. Indications for this procedure include low back pain and the presence of vacuum phenomenon. The objective of this study was to describe a new classification of vacuum phenomenon based on computed tomography scan in order to improve the indications for percutaneous discoplasty.

Methods: We developed a classification of vacuum phenomenon based on computed tomography scan images. We describe 3 types of vacuum based on the relationship between vacuum and the superior/inferior endplates and 2 subtypes based on the presence of significant subchondral sclerosis. A validation study was conducted selecting 10 orthopedic residents with spine surgery training to analyze 25 vacuum scenarios. Inter- and intraobserver reliabilities were assessed through the Fleiss's and Cohen's kappa statistics, respectively.

Results: The overall Fleiss's κ value for interobserver reliability was 0.85 (95% CI 0.82-0.86) in the first reading and 0.93 (95% CI 0.92-0.95) in the second reading. Cohen's κ for intraobserver reliability was 0.88 (95% CI 0.77-0.99).

Conclusion: The new classification has shown almost perfect inter- and intraobserver reliabilities for grading the vacuum phenomenon and could be an important tool to improve the indications for percutaneous cement discoplasty.

Percutaneous Cement Discoplasty for the Treatment of Advanced Degenerative Disc Conditions: A Case Series Analysis.

Global Spine J 2020 Sep 6;10(6):729-734. Epub 2019 Sep 6.

Hospital Italiano de Buenos Aires, Buenos Aires, Argentina.

Study Design: Retrospective analysis. Level of evidence III.

Objectives: To describe the results after a minimum 1-year follow-up in patients treated with percutaneous discoplasty (PD), a minimally invasive technique to treat low back pain in elderly patients with advanced degenerative disc disease. The procedure consists in improving stability by injecting bone cement in a severely degenerated pneumodisc. There are few reports in the literature about this technique.

Methods: Fifty-four patients with advanced disc disease with/without degenerative scoliosis treated with PD with at least 1 year follow-up were studied, variables included clinical (visual analogue scale [VAS] and Owestry Disability Index [ODI]) and radiological parameters (lumbar lordosis and Cobb angle), as well as hospital length of stay and complications.

Results: At 1-year postoperation, significant pain reduction (VAS: preoperative 7.8 ± 0.90; postoperative 4.4 ± 2.18) and improvement in the ODI (preoperative 62 ± 7.12; postoperative 36.2 ± 15.47) were observed with partial correction of radiological parameters (5° mean increase in lumbar lordosis and decrease in Cobb angle). Mean surgical time was 38 minutes, and the mean length of hospital stay was 1.2 days.

Conclusion: PD, currently not a very well-known technique, appears to be-at least in the short-term follow-up-an effective treatment option in selected cases with low back pain due to advanced degenerative disc disease.

[Vertebral cryptococosis. Case report and literature review].

Rev Chilena Infectol 2019 Oct;36(5):656-662

Hospital Italiano de Buenos Aires, Buenos Aires, Argentina.

Cryptococcosis is an infectious disease caused by a ubiquitous encapsulated yeast called Cryptococcus neoformans, it is usually associated with immunosuppressed patients. Osteomyelitis occurs in 5-10%, the spine involvement is one of the most reported. The purpose of this work is to present a case of isolated vertebral cryptococcosis and detail the results of a literature review. The treatment protocol is not yet established but it is recommended to start with aggressive intravenous therapy and continue with a suppressive treatment orally during a variable time. Surgical indication is considered in lesions that affect the spinal stability, deformity or neurological compromise and for local infectious control.

Traumatic Dislodgement of Tibial Polyethylene Insert after a High-Flex Posterior-Stabilized Total Knee Replacement.

Case Rep Orthop 2015 20;2015:810716. Epub 2015 Sep 20.

The Knee Surgery Unit, Institute of Orthopaedics "Carlos E. Ottolenghi", Italian Hospital of Buenos Aires, Potosí 4247, C1199ACK Buenos Aires, Argentina.

Many pathologic entities can produce a painful total knee replacement (TKR) that may lead to potential prosthetic failure. Polyethylene insert dissociation from the tibial baseplate has been described most frequently after mobile-bearing and cruciate-retaining TKRs. However, only 3 tibial insert dislocations in primary fixed-bearing High-Flex posterior-stabilized TKRs have been reported. We present a new case of tibial insert dislocation in a High-Flex model that shares similarities and differences with the cases reported, facilitating the analysis of the potential causes, which still remain undefined.
