Three generations of treatments for osteoporotic vertebral fractures: what is the evidence?

The management of vertebral compression fractures (VCFs) is based on conservative treatment and minimally invasive vertebral augmentation procedures. However, the role of vertebral augmentation is now being questioned by clinical trials and extensive studies. The aim of this review is to report the most relevant evidences on effectiveness, safety, and indications of the currently available vertebral augmentation techniques. Conservative treatment with bracing is effective in reducing acute but it has no effect on segmental kyphosis progression and pseudoarthrosis can occur. Percutaneous vertebroplasty (PV) was the first vertebral augmentation technique to be proposed for the treatment of VCFs. Two blinded and randomized clinical trials compared PV to a sham procedure and no significant differences in terms of efficacy were reported. More recent studies have suggested that PV can still benefit patients with acute VCFs and severe pain at onset. Balloon kyphoplasty (BK) was developed to improve the segmental alignment restoring the height of collapsed vertebrae. BK allows similar pain relief and disability improvement, as well as greater kyphosis correction compared to PV, moreover BKP seems to reduce cement leakage. Vertebral body stenting (VBS) and the KIVA system are third generation techniques of vertebral augmentation. VBS aims to increase the effectiveness in restoring the segmental alignment, while the KIVA system can prevent cement leakage. These techniques are effective and safe, even if their superiority to BK has yet to be proven by studies with a high level of evidence.

[Approach to the athlete with low back pain]. / Prise en charge de la lombalgie chez l'athlète.

Low back pain is a common symptom in athletes, hindering their activity. The etiology is tightly linked to the type of sport, often a consequence of repetitive movements, high pressures and strain being applied to the spine and adjacent muscular and ligamentous structures and a high degree of activity. The diagnosis is the key and causes are usually not severe. However, some red flags may indicate a more serious origin. Treatment is mostly conservative and based on functional therapies with the goal of a rapid and secure return to sports. As such, sedentary lifestyle should be avoided.

La lombalgie est un symptôme courant chez les athlètes pouvant entraver leur pratique sportive. L'étiologie est intimement liée au type d'activité pratiquée, souvent secondaire aux mouvements répétitifs, aux forces appliquées sur les structures musculosquelettiques et au degré d'activité. Le diagnostic clinique reste essentiel pour la prise en charge et les causes sont le plus souvent peu sévères. Des drapeaux rouges peuvent néanmoins alerter la présence d'une atteinte grave nécessitant une prise en charge urgente. L'imagerie immédiate étant indiquée uniquement en leur présence. Le traitement est dans la majeure partie des cas conservateur et basé sur les thérapies fonctionnelles dans l'objectif d'un retour sécuritaire au sport de prédilection dès que possible. La sédentarité, quant à elle, est à proscrire.

Distal femur complex fractures in elderly patients treated with megaprosthesis: Results in a case series of 11 patients.

BACKGROUND: Surgical treatment of complex fractures of the distal femur in the elderly is controversial. Osteoporosis and pre-existent osteoarthritis are common comorbidities in the elderly which add to the need for early walking and rapid restoration of function and also pose significant obstacles to achievement of satisfactory results with standard fixation techniques. Recently, several authors have suggested that primary arthroplasty could be a viable alternative option to standard fixation techniques in selected patients with complex distal femur fractures. AIM: To present our experience with 11 cases of distal femur fractures treated with knee arthroplasty and large femoral resection in a population of patients over the age of 85. METHODS: Data from 11 consecutive patients (10 females, 1 male) presenting with acute intra-articular supracondylar or intercondylar distal femur fractures and with pre-existent primary osteoarthritis who were treated with primary knee arthroplasty were recorded. We collected standard demographic data, comorbidities and patient reported outcomes including Visual Analogical Scale (VAS), Oxford Knee Score (OKS) and Barthel's Index. Post-operative joint range of motion (ROM) and standard radiographic data were also collected. RESULTS: At a mean follow-up of 23.2 mo, all of the implants were well-positioned and osteointegrated. Furthermore, all the patients were alive and walking either independently or with walking aids. There was a marked improvement in pain (VAS 4.5 postop vs 1.9 at the last follow-up), OKS score (29.5 postop vs 36.81 at the last follow-up), ROM (96.2° postop vs 102° at the last follow-up) and restoration of pre-injury ambulatory status (average Barthel Index 77.3). The radiographic evaluations showed good restoration of the articular geometry. No deaths and no complications were recorded. CONCLUSION: In conclusion, we believe that knee megaprosthesis in the case of complex fractures of the distal femur is a valid surgical choice. This is particularly true in elderly patients with severe osteoporosis and pre-existing osteoarthritis. It is important to note that this surgery should be performed by surgeons with proven experience in prosthetic hip and knee surgery and that a scrupulous selection of the cases is completed.

Hand's aneurysmal bone cyst: A rare localization. Case report and systematic literature review.

Aneurysmal bone cysts are benign, rare bony tumours frequently observed among children and young adults principally located in the long bones, pelvis, and spine and rarely in other anatomical district such as the hand. We report the case of a 12-year-old girl with an aneurysmal bone cyst, in active stage, involving the still-open epiphysis of the fourth metacarpal of the right hand, which was in a first time treated by curettage, and 3 months later, occurring a recurrence, by a radically excision of the bone and reconstruction with a graft from the iliac crest. At 10-year follow-up the patient had good cosmetic results and a functioning hand. We also performed a systematic Literature review in order to retrieve the key information regarding: the diagnosis, the clinical features and the treatment.
