Palmar dislocation of the radiocarpal joint.

Radiocarpal dislocation, with or without damage to the radial styloid process or to the distal radial rim, is extremely rare. Review of the literature reveals much confusion on the proper classification of radiocarpal dislocations or fracture-dislocations. A case of radiocarpal dislocation is reported, the classification is discussed, and a critical review of earlier reports is presented.

The influence of epidermal thickness on transcutaneous oxygen pressure measurements in normal persons.

Transcutaneous oxygen pressure measurements (TcPO2) were performed in ten healthy men (age 30.6 years, range 28-35) in six regions: anterolaterally 10 cm below and above the knee on both legs, 5 cm laterally to umbilicus and on the inside of the left humerus, which was subsequently biopsied for measurements of epidermal thickness from the basal lamina to the uppermost layer of stratum granulosum. Transcutaneous oxygen pressure was on average 70 mmHg (range 42-88 mmHg), and that of epidermal thickness 70 microns (range 43-120 microns).

Rupture of the flexor pollicis longus tendon associated with an ununited fracture of the scaphoid.

A 66-year-old man was admitted to the Department of Orthopaedic Surgery, Aarhus County Hospital a few hours after spontaneous rupture of the left flexor pollicis longus tendon. At operation the tendon was found to be ruptured at the radiocarpal level, where an opening to the radiocarpal joint was found. Radiographs showed a long-standing ununited fracture of the scaphoid.

Scintimetry of hip joint tamponade in dogs.

A unilateral, continuous hip joint pressure of 50 mm Hg was established for 6 h in five puppies under general anesthesia. 99mTc-DPD scintimetry 2 and 4 weeks after tamponade showed the mean ratio between the investigated and control hip to be 1.00 and 1.

The contaminated skin-knife--fact or fiction.

Three hundred and fifty-eight patients undergoing clean orthopaedic surgery were included in this prospective study. The knives used during surgery, i.e.

Incarceration of the meniscus in fractures of the intercondylar eminence of the tibia in children.

Four cases of trapping of the meniscus in type II or III fractures of the intercondylar eminence of the tibia in children are reported. At operation the fragments could not be apposed until the meniscus had been lifted out of the fracture. In our opinion, if they had not been operated on these patients would have had persistent trouble in the knee, including non-union, loss of extension and laxity of the anterior cruciate ligament.
