Review Case Reports
Salter-Harris type IV epiphyseal fracture of the proximal phalanx of the great toe: a case report.
Epiphyseal fractures account for about one fifth of pediatric fractures. Approximately 10% cause major growth disturbances, depending on the location and type of the fracture and the skeletal maturity of the child. Intraarticular Salter-Harris type IV fractures are rare, carry a poor prognosis, and almost always need surgical reduction to prevent deformity. We present a case report of a pediatric patient who returned to normal function after the successful surgical reduction of a Salter-Harris type IV fracture in the proximal phalanx of the great toe.

Eighteen patients with ankle injuries presenting as short oblique fractures of the distal fibula with no clinical or radiographic evidence of injury to the medial ankle were studied for fracture displacement. Plain radiographs and computed tomography were used for analysis. All fractures were clinically diagnosed as supination-external rotation stage 2 (SE-II) injuries under the Lauge-Hansen scheme. ⋯ In the majority of patients, the relationship between the talus and distal fibula also appeared undisturbed, with fracture displacement being confined to a change in position of the proximal fibular fragment relative to the tibia as compared with the contralateral ankle. In a minority of cases, in addition to the above-described displacement of the proximal fibular fragment, the distal fibular fragment was noted to shift slightly laterally relative to the talus, with mild widening of the lateral joint space. Occult-associated avulsion fractures off the distal tibia were present in 39% of the cases.

To determine the normal anatomic radiographic land-marks of the ankle syndesmosis, standardized anterior-posterior radiographs of the right ankle were performed on 40 male and 40 female volunteers. The average tibiofibular clear space was 3.8 mm in females, 4.6 mm in males, and 4.2 mm overall. The tibiofibular overlap measured 6.0 mm in females, 9.6 mm in males, and 7.8 mm overall. ⋯ Our data show that for 90% prediction intervals, the values are: (1) tibiofibular clear space less than 5.2 mm in women and 6.5 mm in men; (2) tibiofibular overlap of greater than 2.1 mm in females and 5.7 mm in males; (3) tibiofibular overlap:fibular width ratio greater than 24%; (4) tibiofibular clear space:fibular width ratio less than 44%. Additionally, using a linear regression model, a prediction of the tibiofibular overlap can be made when using the distance (in millimeters) from the incisura fibularis to the lateral tibial (LT) border: tibiofibular overlap = 0.862 x lateral tibia - 2.62 (P = .0001). Utilization of these values will help in the determination of posttraumatic disruption of the syndesmosis and postoperative assessment of mortise reduction.

Randomized Controlled Trial Clinical Trial
Ankle performance after ankle fracture: a randomized study of early mobilization.
In a prospective, randomized study, 30 patients were evaluated after ankle fracture treated by means of open reduction and internal fixation. The patients were randomized to either postoperative immobilization in a plaster cast for 6 weeks or early mobilization (1-2 weeks after surgery) in an ankle brace. Both regimens allowed weightbearing. ⋯ This impairment was significantly less in the brace group. At 12 months, range of motion of the ankle and subtalar joints was restored, but dorsiflexion was still better in the brace group. Score values from a functional score did not correlate with muscle strength.

Randomized Controlled Trial Clinical Trial
Local anesthesia for postoperative pain relief after foot surgery: a prospective clinical trial.
A prospective, randomized, controlled clinical trial was set up to test whether the addition of ankle block to general anesthesia was useful in providing postoperative pain relief following forefoot surgery. Forty feet (20 treatment, 20 control) were entered into the trial and all underwent bony operations on the first ray. ⋯ A significant difference was found between the pain scores in the two groups at the 6-hr stage, but there was no difference in any of the other assessments. It is concluded that ankle block is a useful addition to general anesthesia for this type of surgery.
