Primary epiphyseal osteomyelitis in children. Report of three cases and review of the literature.

In the literature 21 children have been reported with haematogenous osteomyelitis involving only the epiphyses of long bones; in 20 the epiphyses of the knee were involved and the radiographs showed a lytic lesion. Most patients gave a history of pain, limp or refusal to walk for weeks or months without general illness. The erythrocyte sedimentation rate and white cell count were of little diagnostic value, but a bone scan was usually positive. All the patients were cured by antibiotics alone or in combination with curettage.

Alcohol involvement in violence. A study from a Danish community.

All cases of assaults with violence (n = 1639) from a well defined area were registered for 1 year. A positive alcolmeter test (% greater than 0.2) was registered in 488 cases (29%). A further 216 patients (13%) were found under the influence of alcohol according to a simple clinical judgement. In nine of ten manslaughter and murder cases alcohol was involved. Young men, 19-29 years of age, comprised the majority of victims. Of the episodes of violence 66% took place during the weekend. In 250 cases the alcohol concentration surpassed 1.5%. Almost 50% of the violence episoded took place in or around restaurants. Blunt violence was concerned in 73% of the episodes. Gunshot was registered in five cases, stabbings in two cases.

Interpersonal violence: patterns in a Danish community.

We studied all cases of assault with violence (1,639) in a Danish population of 275,000 over a one-year period. Most victims were young men. The incidence rose during evenings, nights and weekends, and assaults were often seen in or around bars and restaurants. Women accounted for 64 per cent of all victims of assault in the home. Influence of alcohol was identified in 43 per cent of all cases. The fist was the most frequent agent of assault; use of firearms was a very rare act of violence but was associated with death in three out of five cases. There were 10 deaths in all.

Mechanical loosening after hip replacement. Incidence after 10 years in 125 patients.

From our first 186 Charnley hip replacements 125, retained for more than 10 years, were examined clinically and radiographically. There were radiographic signs of definite or probable loosening of one or both prosthetic components in 29 per cent of the hips. However, there was a poor correlation between the clinical and the radiographic results, as 86 per cent of the hips were free from significant pain. The loosening rate for males under 60 years of age at the time of the operation was four times higher than for females in the same age group. We suggest that this high-risk group should be followed radiographically, so that a revision, if necessary, can be considered while the bone stock is still sufficient.

Posttraumatic scapholunate dissociation detected by wrist cineradiography.

Thirty-two consecutive patients who had routine x-ray films were examined 12 days after wrist injury because of persistent signs and symptoms of wrist derangement. All patients had the injured and contralateral uninjured wrist examined by fluoroscopy and a scapholunate dissociation was observed in three patients. This study shows that the diagnosis of scapholunate dissociation cannot always be established by routine x-ray examination. The diagnosis should not be based solely on the size of the scapholunate gap in the injured wrist, but on the difference in the size of the gaps between the injured and contralateral uninjured wrist. The three patients with scapholunate dissociation had the defect repaired by open reduction, fixation of the scaphoid by Kirschner wires to surrounding bones, and suture of the dorsal scapholunate ligament. Two of the three patients had a satisfactory result.

An analysis of the function of the posterior talofibular ligament.

The function of the posterior talofibular ligament was studied using an apparatus which subjected the ankle joint to a measured torque and allowed the simultaneous recording of rotatory movements in two planes. Thirty osteoligamentous preparations of ankle joints were examined, half in the sagittal and horizontal planes and the remainder in the sagittal and frontal planes. Successive section of the lateral collateral ligaments was performed, including, in particular, selective division of the short and long fibres of the posterior talofibular ligament. The function of this ligament was investigated in combination with the other two collateral lateral ligaments, with the calcaneofibular ligament alone, and finally as the only remaining intact ligament. The posterior talofibular ligament plays only a supplementary role in ankle stability when the lateral ligament complex is intact. After rupture of the anterior talofibular and the calcaneofibular ligaments, however, the short fibres of the posterior ligament restrict internal and external rotation, talar tilt, and dorsiflexion, while its long fibres inhibit only external rotation, talar tilt, and dorsiflexion. As the posterior talofibular ligament has no independent stabilizing function in the intact ankle joint, an isolated rupture of this ligament is unlikely.

Bone scintigraphy in the evaluation of fracture of the carpal scaphoid bone.

The purpose of the present prospective study was to assess the value of 99m-Tc-MDP wrist scintigraphy performed as a routine examination in excluding or detecting carpal scaphoid bone fracture. The following conclusions are drawn: 99m-Tc-MDP wrist scintigraphy is of high sensitivity, but low specificity in the detection of scaphoid bone fractures. The scintigraphy is expedient to exclude scaphoid bone fracture, if performed after secondary clinical and radiographic assessment, and guided by negative scintigrams a reduction of clinical examinations, radiographies and superfluous casting days is achieved.

Heat generation in plaster-of-Paris and resulting hand burns.

Four female pupils at a technical school received hand burns while trying to make moulds of their hands using a dental plaster instead of ordinary plaster-of-Paris. In three cases the burns were so severe that several fingers had to be amputated due to irreversible tissue damage. The severity of the burns is explained on the basis of an experimental study where it was demonstrated that the temperature of hardening dental plaster rose to 70 degrees C and had a hardness that was 10-times greater than ordinary plaster-of-Paris. This should serve as a warning against the use of dental plaster in direct casting of living tissue. However, the technique used here is also considered dangerous, as ordinary plaster-of-Paris under certain circumstances could also cause severe burns.

Effects of using dexamethasone and placebo in the treatment of prolapsed lumbar disc.

Previous reports concerning the treatment of symptoms deriving from prolapsed lumbar disc with systemic administration of the potent steroid dexamethasone, have shown favourable results. The present clinical study includes 39 patients with symptoms of prolapsed lumbar disc, treated in a controlled double-blind investigation with dexamethasone or placebo. Twenty patients had provable effect of the treatment, 19 had no effect. Nineteen patients received dexamethasone (13 + effect), 20 received placebo (7 + effect). The groups were fully comparable, and the difference is not statistically significant. During a period of 3 months 50% of the patients who improved by the treatment of either group had recurrences leading to operation. It is concluded that the effect of dexamethasone given intramuscularly does not seem to exceed that of placebo in the treatment of prolapsed lumbar disc.

Individually fashioned prostheses in the treatment of Kienböcks disease.

Four patients with Kienböcks disease were treated with replacement of the lunate bone by individually fashioned silicone-rubber prostheses. Follow-up one to eight years after operation showed good results. It is considered a great advantage to be able to make an exact fit of the implant. It prevents luxation and implies that the operation can be performed in all stages of the disease. This simple operation is a valuable supplement to the different procedures for the treatment of Kienböcks disease.
