The neurilemoma (benign schwannoma) is a benign tumor which arises from the Schwann cells of the peripheral nerves. In an intraosseous localization it is a very rare lesion, only forty cases being reported in the literature, and only two of these with the tumor located in the femur. This paper reports on a patient with a large neurilemoma in the lower part of the left femur.

ReviewCircumferential fusion of the lumbar and lumbosacral spine.
Seventy-four patients with circumferential fusion of the lumbosacral spine have been assessed after a mean follow up of 49.8 months. For the ventral procedure, an anterior interbody fusion with tricortical iliac bone graft was performed. The additional dorsal fusion was according to various techniques with mainly transpedicular internal fixation. ⋯ The results favour the technique of a combined anterior/posterior approach for fusion of the lumbosacral spine in patients with instability and deformity of all three columns, such as fractures and spondylolisthesis of more than 50%. Optimal stability with satisfactory reduction of the deformity may be achieved. The one-stage operation proved to be superior, with less complications and a shorter hospital stay.

Lateral band release for post-traumatic extension contracture of the proximal interphalangeal joint.
In the patient with scarring of just the central band and lateral bands, there is a loss of active and passive flexion of the proximal interphalangeal (PIP) joint because the lateral bands have lost their normal volar shift. Surgical freeing of the lateral bands from the central band using parallel incisions may be required to allow full flexion of the PIP joint. ⋯ All operations were successful, with an average gain in range of motion of 47.5 degrees. This technique is simple, quick, and can be performed effectively on an out-patient basis.

Dynamic sonography in the diagnosis of ligament and meniscal injuries of the knee.
A total of 84 patients with ligament or meniscal injuries of the knee was prospectively examined clinically and under anaesthesia, by arthroscopy and sonography. The sensitivity, specificity, positive and negative predictive values were compared. For sonography a high resolution scanner (Picker LSC 7000 with a 5-MHz transducer) was used. ⋯ Repetitions are possible at will 7. Documentation is included 8. Sensitivity and specificity are very good.
