CT guided diagnostic foot injections.

AIM: To describe a CT technique for guiding diagnostic and therapeutic injections in the hind- and mid-foot. MATERIALS AND METHODS: Over a period of 50 months, 28 individuals were referred for diagnostic and therapeutic hind- and mid-foot injections before possible arthrodesis. A CT technique was developed that allowed entry into the various joints using a vertical approach. Numbers of joints injected were as follows: posterior subtalar, 21; talonavicular, 4; calcaneonavicular, calcaneocuboid, navicular-cuneiform and 5th metatarsocuboid joints, 1 each. RESULTS: All injections but one were technically successful. Significant relief of symptoms was noted by 16 participants, whereas for 9 there was no improvement and for 3 a partial response was achieved. CONCLUSION: CT is a simple and safe alternative to fluoroscopy for guiding diagnostic and therapeutic foot injections, and may be the technique of choice in cases of disordered anatomy.

Tibialis posterior insufficiency occurring in a patient without peronei: a mechanical etiology.

A patient presented with a painful flatfoot deformity, which developed after the onset of a drop-foot secondary to a herniated lumbar disk. On examination, the only functioning muscles were her gastrocnemius-soleus complex and her intrinsic toe flexors. Her affected foot had taken the classic deformity seen with tibialis posterior dysfunction--a valgus heel, midfoot collapse and an abducted forefoot. Peroneus brevis was not functioning and therefore could not be implicated as part of the etiology of this patient's acquired flatfoot deformity. The mechanism in which the ground reaction force produces the foot deformity in a tibialis posterior insufficient foot will be presented.

Open reduction of the severely slipped upper femoral epiphysis.

The results of open reduction of the severely slipped upper femoral epiphysis are reported for 115 hips with an average follow-up of 12 years 11 months (range 2 to 33 years). In 70 hips with a chronic slip and an open growth plate the incidence of complications was low: two developed avascular necrosis, five chondrolysis, and one had both. There were more complications in the 38 hips with an acute-on-chronic slip: six developed avascular necrosis, one chondrolysis, and three had both. Of the seven hips operated upon with a partially fused plate, only one did well. All these complications were obvious within the first year but there were also three hips in the series in which osteoarthritis developed between 10 and 20 years after operation.

Mobility after amputation for failed knee replacement.

Management of the failed total knee replacement is a formidable problem. In a 13-year period, 24 patients with above knee amputation following unsuccessful knee replacement were referred for prosthetic limb fitting. Adequate data was available for 23 patients. At review (or at the time of death), an average of 48.6 months after amputation, only seven of the 23 patients were regular daily walkers, although 10 patients had managed to walk for more than two years; 20 of the 23 used a wheelchair for some part of the day and 12 were confined to a wheelchair.

Controlled pressure casting of tibial fractures: a preliminary report.

A new method for the application of a Sarmiento below-knee plaster brace is described together with the results of its use in 22 fractures of the shaft of the tibia. Adequate control of the fractures was obtained and the rate of union appeared satisfactory. The range of movement of the knee and ankle at the time of removal of the cast were more than two-thirds the normal range in respectively 90 per cent and 80 per cent of fractures of the tibia so treated. Consequently, the need for physiotherapy was reduced.

Replacement of the femoral head by open operation in severe adolescent slipping of the upper femoral epiphysis.

The stages in adolescent slipping of the upper femoral epiphysis are classified in relation to treatment. The operation of open replacement of the displaced femoral head is described, and the results of a personal series of seventy-three such operations are presented. Open replacement is excellent treatment for severe chronic slipping so long as the growth plate is still open. The greater incidence of avascular necrosis in acute-on-chronic cases is probably due to damage to the blood supply of the head at the time of the acute slip or kinking of the vessels before replacement. Prolonged traction before operation may increase the risk of chondrolysis. Late onset of osteoarthritis when neither avascular necrosis nor chondrolysis has occurred may be due to misfitting of the articular cartilage because of inaccurate reduction.
