Emergency Treatment of Cervical Vertebromedullary Trauma: 10 Years of Experience and Outcome Evaluation

OBJECTIVE

The aim of the study is to identify and validate, through the recording of clinical and radiological data, the different surgical approaches and treatments valid for most subaxial cervical dislocation fractures and whether there is an advantage from using an anterior approach rather than a posterior approach and conversely..

MATERIAL AND METHODS

A retrospective study was carried out analyzing the case history of the last 10 years of vertebromedullary traumas treated at the spine surgery unit of the Policlinico Gemelli in Rome. Data on surgical timing, American Spinal Injury Association (ASIA) scores for neurological damage, and subsequent assessments on recovery, survival, and mortality were also examined.

RESULTS

A total of 80 patients were treated: 50 by the posterior approach, 24 by the anterior approach, and six by the double approach. Our average follow-up time was 4.2 years. A prevalence of surgery with the posterior approach was noted. We observed the worsening of cervical kyphosis about 15 months after the trauma in two cases treated with the posterior approach alone. A second surgical treatment was performed in these patients. One of these patients underwent an anterior fusion; the other case underwent a posterior revision because the patient had ankylosing spondylitis. Although we found no statistically significant difference in outcomes between the various surgical treatments, in this retrospective study, we analyzed the characteristics and outcomes of cervical spine injuries that required surgical treatment.

CONCLUSION

The aim of surgery in unstable cervical spine injuries should be to reduce and stabilize the damaged segment, maintain lordosis, and decompress when indicated. The optimal choice of surgical approach and treatment, or its superiority in terms of outcomes, remains a debated issue.

The use of custom-made antibiotic-loaded spacer in periprosthetic knee infection caused by XDR organism: case report and review of literature

Periprosthetic knee infection (PKI) remains one of the most challenging complications after total knee replacement, especially if caused by multidrug-resistant (MDR) or extensively drug-resistant (XDR) organisms. Multiple treatment options are available, such as long-term antibiotic suppression, surgical debridement with retention of the prosthesis, definitive resection arthroplasty, arthrodesis, one-stage or two-stage revision procedures, amputation. We present a rare case of a PKI caused by a XDR Klebsiella pneumoniae in a young patient who underwent a prosthetic reconstruction due to an osteosarcoma of the tibia. In this patient, the PKI has been treated using intravenous administration of Amikacin and an Amikacin-impregnated PMMA custom-made spacer. To our knowledge, only two cases that successfully used hand-mixed antibiotic-loaded spacer based on antibiotic sensitivity for the treatment of PKI caused by MDR and XDR microorganisms have been reported in the literature.

The use of knee mega-prosthesis for the management of distal femoral fractures: A systematic review

INTRODUCTION

Distal femur fractures (DFFs) are unusual and difficult to deal, especially in elderly patients. A consensus about a gold-standard treatment has not been reached yet. Available options include both conservative and surgical management. In elderly patients a prosthetic replacement could be a valid treatment option. Literature is lacking about the use of mega-prosthesis in this type of fractures. The purpose of the present systematic review is to examine which fracture, both acute and chronic, involving distal femur should be treated by using a mega-prosthesis.

MATERIALS AND METHODS

Studies were identified by searching electronic databases. All studies that enrolled people of any age affected by a DFFs treated by using a megaprosthesis were included. Primary outcomes of the present reviews were: ROM, functional assessment and complications. Two review authors independently selected eligible trials. Disagreements at any stage were resolved by consensus or a third party adjudication. Descriptive statics was used to summarize the data.

RESULTS

Thirteen article were finally included in the review. One hundred-four patients were treated with knee megaprosthesis. Three categories of patients were identified: 29 patients were affected by supracondylar femur fracture; 51 patients occurred with a periprosthetic fracture; 24 patients suffered a non-union of a previous supracondylar fracture. The follow-up varied between 6 months to 58 months. All studies showed good results in terms of improving quality of life, resuming activities of daily living (ADLs), early mobilization, ROM, shorter hospital stay. Although not frequent, the only reported complications were infection and aseptic loosening.

DISCUSSION

The present review showed that the use of knee megaprosthetic implants could represent a valid treatment option aiming to reduce patients' immobilitazion and hospital stay. Good clinical outcomes with low rate of complications were reported by all included studies. Literature is lacking about long-term outcomes and complications. Moreover studies comparing knee prostheses and other types of surgical treatment (intramedullary nails, plate fixation system) are needed.

CONCLUSIONS

Megaprosthesis represent a viable treatment option in patients affected by DFFs (either acute, periprostethic or non-union) because they allow immediate weight-bearing, shorter hospital stay, a fast recovery of knee function and ADLs.

A thoracic pain of difficult diagnosis. Unusual localization of osteoid osteoma

Osteoid Osteoma (OO) is a benign tumor that can affect any age, but it occurs mostly in adolescents. Only few cases are reported in early infancy but very rare in advanced age. From our series of OO of the spine, we selected a rare case that combines many unusual features that makes diagnosis very difficult. A case of a painful thoracic syndrome in an old female patient due to an OO localized in the inferior edge of the left pedicle of T11 with engagement of the foramen was reported. The age of the patient, the absence of any typical clinical and diagnostic signs, such as nocturnal pain or side effects to NSAIDs administration, are unusual at presentation of OO. She presented instead, a type of pain to the chest that was stabbing, fulminating and radiating. The interest of the case is due to the association of a variety of clinical aspects that stimulate discussion as well as to the role of the modern investigative diagnostic process.

Percutaneous short fixation vs conservative treatment: comparative analysis of clinical and radiological outcome for A.3 burst fractures of thoraco-lumbar junction and lumbar spine

PURPOSE

The aim of the study is to use an algorithm previously published to decide whether to perform open surgery or percutaneous surgery with short fixation in patients with thoraco-lumbar junction and lumbar spine fractures, and to compare retrospectively surgical and conservative options of treatment.

METHODS

Between 2005 and 2009, two groups of 25 patients were analyzed to compare retrospectively surgical and conservative option of treatment to assess perception of pain and to evaluate quality of life during treatment, to evaluate how quickly patients return to work and to their daily activities, to evaluate patients' satisfaction. X-ray controls were performed to evaluate the fusion rate at 3 and 6 months and CT scans at 6 months.

RESULTS

The surgical group had a better functional recovery, a better quality of life and returned to work earlier in comparison to the conservative group.

CONCLUSIONS

We can conclude that the percutaneous procedure seems to give better results in terms of satisfaction and return to normal activities, although both procedures guarantee excellent fusion rates.
