Prognosis of primary anterior shoulder dislocation in young adults.
From 1982 to 1987, 194 patients with 196 primary traumatic anterior shoulder dislocations were treated in our hospital. One hundred and sixty-six patients with 168 shoulder dislocations (87%) were available for study at follow-up an average of 4 years after treatment. The most important prognostic factor in relation to recurrence was the age of the patient at the time of the primary dislocation. ⋯ Athletes in this age group had no worse a prognosis as to recurrence than non-athletes. A fracture of the greater tuberosity improved the prognosis significantly (P less than 0.01). Neither the presence of a Hill-Sachs lesion nor the period of immobilization influenced the recurrence rate in patients aged 30 years and younger.

Case ReportsTreatment of fractures of the humeral capitulum using fibrin sealant.
Three patients with fresh displaced fractures of the capitulum humeri were treated by the fibrin sealant method, without additional internal fixation. At follow-up, between 1 1/2 and 4 1/2 years after surgery, clinical results were very good. Fibrin sealant has many advantages over traditional osteosynthesis techniques and is therefore recommended as an effective method for treating such serious but uncommon fractures of the elbow joint.

Comparative StudyBone formation in porous implants of delrin and commercially pure titanium.
Clinicians have been using implants made by titanium or delrin with varying results. In this study dividable implants, bone growth chambers (BGC), of titanium and delrin were inserted into the rabbit tibia. ⋯ Results showed that bone ingrowth into titanium implants was significantly larger than into delrin implants (P less than 0.005). The possible reasons for this are discussed.

Comparative StudyCurrent evaluation of sonography of the meniscus. Results of a comparative study of sonographic and arthroscopic findings.
Sonography of the knee has gained in significance in the diagnosis of the meniscus; experimental and clinical studies have demonstrated that the normal and pathological anatomy of the meniscus can be visualized on a sonogram. The aim of this comparative investigation is to evaluate sonographic lesion diagnosis in comparison with arthroscopic findings, using a standardized examination method. Two hundred and six knee joints were first scanned sonographically using a 7.5 MHz sector transducer. ⋯ The patients were of varying ages and had varying anamneses. The results show that sonography of the meniscus is a valuable diagnostic help when the knee-joint symptoms are not clear, given that the correct technical equipment and sufficient experience with this form of examination are at hand. The advantage of sonography is that, in contrast to arthroscopy, it is noninvasive and easily available.

Comparative StudyDiagnostic value of serum tumor markers in skeletal metastasis of carcinomas.
Levels of serum tumor markers including tissue polypeptide antigen (TPA), CA 15-3, CA 19-9, squamous cell carcinoma antigen, carcinoembryonic antigen, alpha-fetoprotein, and PAP were measured in 26 patients with bone metastasis and in 9 patients with primary bone tumors. More than one markers was elevated in 19 of the 26 patients with bone metastasis, although there was no elevation of the markers in 3 patients with renal cell carcinoma. TPA was the most sensitive marker in the diagnosis of metastasis. ⋯ On the other hand, there was a slight elevation of the markers observed in two of the nine patients with primary bone lesions. Serum tumor markers are useful in the diagnosis of bone metastasis to differentiate it from primary bone lesions. Especially in solitary bone lesions, serum markers may be the only way to make a differential diagnosis between the two.
