The Authors discuss the cases treated in the Fatebenefratelli Hospital in Erba in the period 1975-80 and propose strengthening of the quadriceps muscle as first treatment of knee cap instability.

The authors review the results of 100 cases of idiopathic scoliosis treated surgically by the Harrington procedure. The mean remove was 31 months. After a brief introductory section dealing with preparation methods, the paper illustrates the technicalities of the procedure, the usefulness of correction in two stages with a fortnight interval, the various types of mounting and postoperative care. They assess the improvement obtained in terms of vertebral rotation (mean correction achieved: 4.6 degrees, representing 10%) and of lateral flexion (49% improvement over pretreatment values), and they discuss in particular the need for a correct choice of instrument placement and appropriate evaluation of arthrodesis extent in view of avoiding loss of correction. While they acknowledge the value of the Harrington procedure in regard to correction of lateral flexion, the authors propose further refinement of the original method to include correction of vertebral rotation and so improve on current results.
The authors review a number of more or less original technics of posterolateral vertebral arthrodesis, and report published results relative to intersomatic, posterior, and posterolateral arthrodesis. To this they add a presentation of their own cases treated by posterolateral arthrodesis, noting that this method is not unduly difficult to perform and gives good results in a high percentage of cases.
The authors review the cases of Ledderhose's disease come to their observation at the "Gaetano Pini" Orthopedic Clinic of Milan. They explain that this condition, formerly regarded as extremely rare, can no longer be considered such in the light of modern observations. After giving a brief discussion of clinical and anatomopathological features, they state that the condition is essentially benign and often associated with Dupuytren's disease. They also believe that surgical correction should be done only in the more severe instances, and comment on the extreme rarity of relapses in cases treated surgically.

This paper describes the various technics of orthopedic surgery currently used to correct scoliosis and maintain correction. Among corrective methods they illustrate the use of the Cotrel plaster corset (E.D.F.) preceded by passive bipolar traction and autoelongation. Once correction is achieved, it must be maintained to the end skeletal growth; this is done with various types of orthopedic corsets (Lyonnais, La Padula, Milwaukee), which are used according to the patient's age and anatomical type of deformity. The authors discuss in particular the forces that are applied to the occiput and mandible with the Milwaukee corset (Logan, Cochran and Waugh), the values being recorded in diverse situations including the upright stance, ambulation, sitting position, position, supine position, and sleep (Galante, 1970). The authors also made a comparative study of the conventional Milwaukee corset (with broad chin bearing) versus the Milwaukee with hyoid bearing; and finally they illustrate the results obtained by Andriacchi and his associates in selecting the Milwaukee corset for patients with idiopathic scoliosis on the basis of the mathematical model of the rachis.

The authors describe a rare case of bilateral congenital aplasia of the femur, seen by them at a Center for Motor Rehabilitation of the "La Nostra Famiglia" organization. They offer a complete clinical and roentgenographic documentation of the case, which was compounded by the presence of other congenital malformations.

Two continuous series of McKee-Farrar type metal-metal and Charnley type metal-plastic prostheses have been examined. Results are analysed and complications examined ten years after the operation. The McKee-Farrar prostheses showed inferior results in all parameters and a markedly higher incidence of late complications compared to the Charnley prostheses.
