The transcutaneous electrospinal treatment adds another approach to the conservative treatment of small and moderate idiopathic scoliotic curves. The method presented here is readily accepted by both the adolescent and the parents. It is inexpensive, and allows flexibility as to the location and number of electrodes to be used and the curve treated. The data presented here, collected over a five-year period of clinical monitoring and recording, indicate that results are favorable, therefore, the method is acceptable.
An experimental double-blind study to evaluate the effectiveness of a constant current stimulator was performed on 30 young pigs that underwent a spinal fusion at the level of L5-L6. The group of animals with an active bone-growth stimulator showed a statistically significant increase of osteoblastic activity with bone formation.
Three patients underwent hip arthroplasty--one total hip replacement and two, Thompson's hemiarthroplasty. The diagnosis was degenerative joint disease and subcapital fracture of the femur, respectively. Histologic and bacteriologic examination revealed mycobacterial infection. None of the patients had a past history of mycobacterial infection. In one instance, there was a reactivation of the infection eight months following surgery, which was treated successfully by antituberculosis drugs.
More than half the patients with permanent cardiac pacemakers (PCPMs) are over the age of 70 years. Patients in this age group are also more susceptible to fractures of the femoral neck requiring surgical intervention. The authors studied five patients with PCPMs who underwent surgery for femoral neck fracture. They discuss the special precautions necessary during surgery to prevent electromagnetic interference with the cardiac pacemaker as well as the special management of these patients.
An adult patient with isolated septic arthritis of the sternoclavicular joint (SCJ) caused by Staphylococcus aureus is described. The patient had no underlying diseases other than paronychia, which might have served as the portal of entry. Antibiotic therapy resulted in clinical cure but x-ray revealed progression of the destructive process.
Two patients suffering from Paget's disease, involving the hip joint, with pain and limitation of movement, were treated by total hip replacement. The operative course was normal and without excessive bleeding. At follow-up five years later, the patients are free of pain, and have almost complete range of motion; there is no sign of prosthetic loosening.
Fifteen patients with patellofemoral pain resulting from patellar malalignment had coronal plane osteotomy of the patella. Patients were followed for an average of three years, and all results except one were favorable. The relief of pain was attributed to both the reduction of intraosseous pressure including associated biological adaptations and the mechanical realignment of the patella.
Five patients with spondylolisthesis which caused symptoms were treated by spinal fusion and direct current bone-growth stimulation. After ten weeks bony fusion was observed and the patients returned to their normal activities. The implanted stimulator appears to promote early fusion.
A bilateral distal femoral epiphysiolysis was observed in a 28-month-old child suffering from scurvy. We explain the mechanisms of the separation of the epiphysis due to loss of strength in the calcification zone of the cartilage columns.

In an experimental study of 60 rabbits (120 preparations) in which a bilateral fibular osteotomy was performed, a group of 40 rabbits had ligation of the vena cava, and a group of 20 rabbits were used as controls. The results were evaluated by microscopic study by H&E, PAS abd Alcian Blue staining and showed that venous stasis accelerates the process of fracture healing by increasing fibroblastic and osteoblastic proliferation and bone production. The effects of changes in pH, and concentrations of oxygen and carbon dioxide are suggested as the factors that modify the mechanism of osteogenesis, and greater quantities of mucopolysaccharide substances were observed at the fracture site in the group with venous stasis.
Five patients with sarcoma of the distal end of the femur were treated by a total resection of the femur and its replacement by an endoprosthesis. This was to preserve the body image, prevent mutilation and permit independent ambulation. A chemotherapy program was established with administration of a high dose of methotrexate plus citovorum factor, adriamycin and vincristine. surgical removal of pulmonary metastases and other local recurrences was performed where and when possible. The functional results were excellent in four and poor in the remaining patient. All of the patients rapidly achieved physical rehabilitation and developed a stable and painless gait. This approach to the treatment of osteogenic sarcoma attempts to eliminate the primary tumor, the micrometastases and the overt metastatic disease, leaving the patient to follow as normal a life a possible, which is not the case when a high thigh amputation or a hip disarticulation is performed.
