Comparative StudyThe Tikhoff-Linberg procedure for bone tumors of the proximal humerus: the classical "extensive" technique versus a modified "transglenoid" resection.
The authors report on two groups of patients (each with 12) with primary bone tumors of the humerus who underwent either a classical Tikhoff-Linberg (T-L) procedure or a modified technique by which the body of the scapula was saved. The latter procedure was an "en bloc" resection of the glenohumeral joint after an extra-capsular osteotomy of the neck of the scapula, followed by reconstruction with a modular prosthesis. ⋯ Besides producing better aesthetic and functional results, the modified technique offered the advantages of shorter anesthesia time, less blood loss, and a better anchorage of the prosthesis. The results of this study show that the proposed modification of the T-L procedure is indicated in patients with bone tumors of the proximal humerus in which invasion of the joint capsule is present without macroscopic involvement of the glenoid.

Case ReportsCorrection of clubfoot relapse using Ilizarov's apparatus in children 8-15 years old.
Treatment of relapsed or neglected clubfeet between the age of 8-15 years is at present unsatisfactory. Correction by triple arthrodesis with wedge osteotomies is not possible before the end of skeletal maturation. This caused us to use Ilizarov's external fixator, which made it possible to correct all components of clubfoot simultaneously by continuous guided distraction. ⋯ A plantigrade foot was achieved in all cases. All patients were able to wear ready-made shoes. Complications were some slight and two severe pin track infections, temporary edema, and two relapses successfully treated by means of second procedures.

Case ReportsWhich X-ray views are required in juvenile ankle trauma?
Although ankle sprains are probably the most common injury in adolescent sports people, epiphyseal injuries are missed on the presumption of a ligamentous tear. The risk of damaged ligaments has been overemphasized while the potentially dangerous epiphyseolysis has been understressed. An oblique X-ray of the ankle joint is indicated prior to "stress" pictures.

Comparative StudyAutomated percutaneous lumbar discectomy with and without chymopapain pretreatment versus non-automated discoscopy-monitored percutaneous lumbar discectomy. An experimental study in human cadaver spines.
Percutaneous lumbar discectomy has gained growing interest during recent years as an alternative to open surgery for protrusions and non-sequestrated subligamentous intervertebral disc herniations. As a less invasive method it competes with chemonucleolysis. At least two modifications are known to date: automated percutaneous lumbar discectomy (APLD) with a 2-mm suction probe and non-automated, discoscopy-monitored percutaneous lumbar discectomy with a suction rongeur and a motor-driven shaver (NAPLD). ⋯ By contrast, the rongeur, which first cuts the material to be removed and then carries it away by suction, was much more effective. Further data to support the advantages of non-automated percutaneous nucleotomy are discussed. Pretreatment of the disc with chymopapain did not result in a higher yield of nucleus material when combined with APLD.

Case ReportsBilateral pseudarthrosis of the femur after stress fracture.
Stress fractures of the diaphysis of the femur are very rare, particularly bilateral ones. We describe here a woman patient with bilateral pseudoarthrosis of the femoral diaphysis which was the result of a stress fracture. ⋯ The patient has been closely examined for over 30 years. Our own explanation for the beginnings of stress fracture as well as for the pseudarthrosis development are given.
