Orthopaedic treatment in tibial diaphyseal fractures. Risk factors affecting union.
A retrospective of 216 tibial fractures treated orthopedically was carried out. The aim was to analyze a set of clinicobiological parameters that owing to their assumed action on the physiological model of consolidation can be considered as risk factors to be taken into account in all kinds of orthopedic treatment, because they may lead to a lengthening of the normal consolidation time of the fracture. The variables analyzed were the following: type of immobilization, causative agent of the fracture, location of the focus of the fibular fracture, initial displacement, degree of conminution, type of wound, type of fracture, appearance of radiologically observable callus, commencement of weight-bearing, post-fracture hematoma, secondary displacement, and infection of soft tissues. In the particular case of immobilization by an ischiopedic plaster cast, the following parameters showed a greater degree of prognostic significance: initial displacement, secondary displacement, and age.

Case ReportsPseudoarthrosis of the ulna in neurofibromatosis. A report of four cases.
Four children suffering from neurofibromatosis with ulnar pseudarthrosis and progressive reabsorption of the middle and distal thirds of the ulna are reported. None had any pain or sensory loss, but all had progressive deformity of the forearm. ⋯ Non-operative management was decided on in the patient with slow ulna reabsorption. The creation of a one-bone forearm is more likely to produce sound union, thus avoiding the need for further operations, while conservative management should be reserved for patients with a slowly progressive condition.

Ultrasound diagnosis of pathology of the anterior and posterior cruciate ligaments of the knee joint.
We established a method of diagnosing pathologic conditions of both the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) by using ultrasound. Normal ACL and PCL were delineated as hyperechoic images on the screen in sagittal and transverse sections. ⋯ We examined nine ACL and five PCL injuries by our method. This is a safe and an effective method of determining the rupture of ACL and PCL.

Case ReportsBilateral stress fracture of the scaphoid. A case report.
Bilateral stress fractures of the scaphoid bones in a gymnast are reported and discussed with special consideration of the possible differential diagnoses; bipartite scaphoid and pseudarthrosis of the scaphoid bone. The relevance of the mechanical factors involved and the abduction and dorsiflexion of the wrist in gymnastics are suggested as likely pathomechanisms.

Operative procedure using the improved osteosynthesis technique for intertrochanteric osteotomies. Preliminary report.
Employing a simple sawing gauge system in intertrochanteric osteotomies, it is possible to effect "functional pre-bending" of the angled blade plate osteosynthesis in order to achieve better interfragmentary compression and further improve the precision of the standardized AO technique. This new technique may lead to a further reduction of intraoperative and post-operative failures.
