During the years 1973-5 we performed 190 meniscectomies. We report 4 cases of tears of the anterior cruciate ligament after meniscectomy. Although this complication is mentioned in the literature, very few orthopaedic surgeons are familiar with it.

Fracture healing was studied in 28 rabbits after their femurs had been osteomized using the carbon dioxide laser. Twenty rabbits whose femurs were osteotomized by means of a Gigli saw served as the control group. Fracture healing was initially delayed in the laser cut femurs, yet after 60 days no significant difference between the groups could be detected. The initial delay was caused by thermal damage to the laser cut bone edges. Further fragmentation of the damaged bone occurred during the immediate postoperative period.
Bilateral simultaneous elongation of the lower limbs was performed in 3 achondroplastic children. A total of 10 bones were elongated with Wagner's distraction apparatus, mainly by a modified Wagner technique. Maximal elongation of 34 to 44% of the original bone length resulted in relatively minor complications. Elongation of the lower limbs in achondroplastic children improves trunk-to-lower-limb proportions.

During armed combat serious hand injuries are often neglected only to receive the attention they deserve far too late. The authors have employed a vigorous approach to the primary care of severe war injuries to dorsum of the hand introducing silicone rods where extensor tendons have been destroyed and where skin closure is obtained using inguinal skin flaps.

The laser beam can be adapted for use as a surgical cutting instrument. It was chosen for this purpose in the extirpation of an osteoma of the skull. Its removal by conventional means was believed to be too dangerous, because of surrounding vascularity. The nature and properties of the beam and its surgical applications are discussed briefly.
