Restoration of elbow flexion by latissimus dorsi myocutaneous or muscle flap.
Six patients with flail elbow as a consequence of brachial plexus injury or traumatic loss of arm muscles underwent bipolar transposition of latissimus dorsi myocutaneous or muscle flaps to the biceps brachii to restore elbow flexion. The muscle strength achieved was 1.5-2.5 kg and the total range of active excursion is about 95 degrees. ⋯ Elbow flexion of more than 120 degrees is necessary for the affected hand to reach the mouth and should be one of the goals of the operation. Versatile use of the myocutaneous flap facilitates skin closure and improves the contour of the arm.

Case ReportsTransient palsy of hip abductors after a fall on the buttocks.
A fall on the buttocks caused monolateral transient palsy of the hip abductors in two patients. Palsy could be ascribed to acute entrapment of the superior gluteal nerve between the piriformis muscle and the incisura ischiadica major.

The growing propagation of hip-joint sonography and its increasing use as a screening method make it important to point out some potential mistakes. Good image quality, three-dimensional evaluation with real-time technique, consideration of form variants, correct estimation of angle parameters, consideration of medical history, and clinical evaluation as well as the necessity of follow-up examinations are inevitable requirements for reliable diagnostic sonography of the hip joint.

Kienböck's disease with onset after 50 years of age was studied. Of 127 patients with Kineböck's disease seen over the past 30 years, the cases of 15 (12 female, 3 male) were analyzed. The average age of onset was 58.3 years. ⋯ Moreover, it was noteworthy that the variance among aged controls (group C) was higher than among the young controls (group D). The metacarpal index of the patients with aged-onset Kienböck's disease was markedly lower than that of the young. Considering the increase of ulnar variance with age, the persistence of minus variance and the presence of osteoporosis might make the lunate bone susceptible to injury.

Case ReportsTreatment of an old infection in a total hip replacement with an interim spacer prosthesis.
When treating a septic hip-joint prosthesis with bone loss of the proximal femur secondary to osteomyelitis, we implanted a specially designed prosthesis to act as a local antibiotic and spacer between the acetabulum and femur until the infection abated. Arthroplasty could then be carried out with no trouble and there was no recurrence of infection.
