[Low back pain in 2006: back to the root].

Low back pain is a major burden for health care. According to the International Classification of Function, it is a disability of complex origin. Risk factors for chronification are of psychosocial and not physical nature. Primary targets of treatment should be physical fitness and the self-management of problem by the patient. Awareness of the psychosocial factors (yellow, blue and black flags) which can disturb occupational reintegration should be developed. Rehabilitation is based on measures to modify patient's beliefs and fitness. The prescribed treatment should aim to relieve pain, correct disability, prevent relapses, inform and educate the patient. Every low back pain sufferer which does not improve in 1 month should be sent to a team skilled in handling this kind of problem.

[Surgical indications in spinal trauma].

Surgical indications in spinal trauma remain a controversial topic. In general, unstable cervical injuries such as displaced odontoid fractures, burst fractures or tear drop fractures require surgical intervention. Thoracolumbar compression injuries without posterior wall involvement or significant kyphosis can be treated conservatively. Surgery is indicated in fractures-dislocations and burst fractures with significant canal narrowing and/or major kyphosis. The role of emergency decompression as well as that of steroids remain uncertain since no study to date has convincingly proven their efficacy.

[Percutaneous vertebroplasty].

Although vertebroplasty was initially a treatment of vertebral haemangioma or metastases, this procedure is now frequent option to the treatment of osteoporotic vertebral fractures. In this review article, we will discuss the indication, the techniques and the follow-up of the vertebroplasty. This is a risky procedure, which should be performed by experimented physicians working with high-resolution fluoroscopic equipments, by biplane fluoroscopy, to reduce the risk and irradiation to the patient. According to the available follow-up studies, there is clear evidence of a strong improvement of quality of life after vertebroplasty by rapid decreasing of back pain at least during the first six months. Other new studies will analyze the long-term follow-up after vertebroplasty.

Modified triangular posterior osteosynthesis of unstable sacrum fracture.

We report preliminary results for unstable sacral fractures treated with a modified posterior triangular osteosynthesis. Seven patients were admitted to our trauma center with an unstable sacral fracture. The average age was 31 years (22-41). There were four vertical shear lesions of the pelvis and three transverse fracture of the upper sacrum. The vertical shear injuries were initially treated with an anterior external fixator inserted at the time of admission. Definitive surgery was performed at a mean time of 9 days after trauma. The operation consisted in a posterior fixation combining a vertebropelvic distraction osteosynthesis with pedicle screws and a rod system, whereby the transverse fixation was obtained using a 6 mm rod as a cross-link between the two main rods. Late displacement of the posterior pelvis or fracture was measured on X-ray films according to the criteria of Henderson. The patients were followed-up for a minimum time of 12 months. Four patients who presented with a pre-operative perineal neurological impairment made a complete recovery. No iatrogenic nerve injury was reported. One case of deep infection was managed successfully with surgical debridement and local antibiotics. All patients complained of symptoms related to the prominence of the iliac screws. The metalwork was removed in all cases after healing of the fracture, at a mean time of 4.3 months after surgery. No loss of reduction of fracture was seen at final radiological follow-up. The preliminary results are promising. The fixation is sufficiently stable to allow an immediate progressive weight-bearing, and safe nursing care in polytrauma cases. The only problem seems to be related to prominent heads of the distal screws.

Multi-purpose HealthCare Telemedicine Systems with mobile communication link support.

The provision of effective emergency telemedicine and home monitoring solutions are the major fields of interest discussed in this study. Ambulances, Rural Health Centers (RHC) or other remote health location such as Ships navigating in wide seas are common examples of possible emergency sites, while critical care telemetry and telemedicine home follow-ups are important issues of telemonitoring. In order to support the above different growing application fields we created a combined real-time and store and forward facility that consists of a base unit and a telemedicine (mobile) unit. This integrated system: can be used when handling emergency cases in ambulances, RHC or ships by using a mobile telemedicine unit at the emergency site and a base unit at the hospital-expert's site, enhances intensive health care provision by giving a mobile base unit to the ICU doctor while the telemedicine unit remains at the ICU patient site and enables home telemonitoring, by installing the telemedicine unit at the patient's home while the base unit remains at the physician's office or hospital. The system allows the transmission of vital biosignals (3-12 lead ECG, SPO2, NIBP, IBP, Temp) and still images of the patient. The transmission is performed through GSM mobile telecommunication network, through satellite links (where GSM is not available) or through Plain Old Telephony Systems (POTS) where available. Using this device a specialist doctor can telematically "move" to the patient's site and instruct unspecialized personnel when handling an emergency or telemonitoring case. Due to the need of storing and archiving of all data interchanged during the telemedicine sessions, we have equipped the consultation site with a multimedia database able to store and manage the data collected by the system. The performance of the system has been technically tested over several telecommunication means; in addition the system has been clinically validated in three different countries using a standardized medical protocol.
