چکیده
The treatment of simple radial head fractures type Mason-Hotchkiss 1 and 2 is unequivocal. In the case of a displacement of less than 2 mm (MasonHotchkiss 1), functional conservative treatment is indicated. If the displacement is more than 2 mm (Mason-Hotchkiss 2) internal fixation is indicated, combined with treatment of the soft-tissue injuries. The treatment of comminuted radial head fractures Mason-Hotchkiss type 3 is more controversial, as they are usually associated with ligament injuries. Conservative treatment appears to have unsatisfactory results. Opinions differ on surgical treatment, i.e. 1) excision of the radial head ; 2) reconstruction by means of internal fixation ; 3) excision and reconstruction with a prosthesis. Basic experimental research on human cadaver elbows shows the importance of the conservation of the radial head, especially in case of associated soft tissue injuries. In most cases a stable osteosynthesis is impossible, and in case of associated ligament disruptions, resection and reconstruction by means of a rigid radial head prosthesis should be considered. Experimental research demonstrates promising results for rigid radial head prostheses in human cadaver elbows with a resected radial head and failing medial collateral ligament. Short-term clinical studies seem to confirm this, but long-term results are as yet unknown.

Meniscal Roots: Current Concepts Review
Meniscal root tears are defined as radial tears located within 1 cm from the meniscal attachment or a bony rootavulsion. This injury is biomechanically comparable to a total meniscectomy, leading to compromised hoop stressesresulting in decreased tibiofemoral contact area and increased contact pressures in the involved compartment.These changes are detrimental to the articular cartilage and ult...
متن کاملPosterior Cruciate Ligament: Current Concepts Review
The posterior cruciate ligament (PCL) is the largest and strongest ligament in the human knee, and the primary posteriorstabilizer. Recent anatomy and biomechanical studies have provided an improved understanding of PCL function. PCLinjuries are typically combined with other ligamentous, meniscal and chondral injuries. Stress radiography has becomean important and validated objective measure in...
متن کاملPost spinal puncture headache, an old problem and new concepts: review of articles about predisposing factors
Post spinal puncture headache (PSPH) is a well known complication of spinal anesthesia. It occurs after spinal anesthesia induction due to dural and arachnoid puncture and has a significant effect on the patient’s postoperative well being. This manuscript is based on an observational study that runs on Babol University of Medical Sciences and review of literatures about current concepts about t...
