Objectives. Overlap between the distal tibia and fibula has always been quoted to be positive. If the value is not positive then an injury to the syndesmosis is thought to exist. Our null hypothesis is that it is a normal variant in the adult population. Methods. We looked at axial CT scans of the ankle in 325 patients for the presence of overlap between the distal tibia and fibula. Where we thought this was possible we reconstructed the images to represent a plain film radiograph which we were able to rotate and view in multiple planes to confirm the assessment. . Results. The scans were taken for reasons other than pathology of the ankle. We found there was no overlap in four patients. These patients were then questioned about previous injury, trauma, surgery or pain, in order to exclude underlying pathology. Conclusion. We concluded that no overlap between the tibia and fibula may exist in the population, albeit in a very small proportion

In this retrospective study, we assessed the outcome in 99 patients who underwent reconstruction of the lateral ligaments of the ankle for chronic anterolateral instability with a minimum follow-up of 15 years. Two techniques were compared: 54 patients had an anatomical reconstruction (AR group) and 45 had an Evans tenodesis (ET group). They were followed up for 19.9 ± 3.6 years and 21.8 ± 4.6 years, respectively. During follow-up, seven patients in the AR group and 17 in the ET group required a further operation (p = 0.004). At follow-up, significantly more patients (n = 15) in the ET group had limited dorsiflexion than in the AR group (n = 6, p = 0.007) and 18 in the ET group had a positive anterior drawer test compared with seven in the AR group (p = 0002). In the ET group 27 had tenderness on palpation of the ankle compared with 15 in the AR group (p = 0.001). Stress radiographs showed ligamentous laxity significantly more often in the ET group (n = 30) than in the AR group (n = 13, p < 0.001). The mean values for talar tilt and anterior talar translation were significantly higher in the ET group than in the AR group (p < 0.001, p = 0.007, respectively). There were degenerative changes on standard radiographs in 32 patients in the AR group and 35 in the ET group (p = 0.05). Four patients in the ET group had developed severe osteoarthritis compared with none in the AR group (p = 0.025). Assessment of functional stability revealed a mean Karlsson score of 83.7 ± 10.4 points in the AR group and 67.0 ± 15.8 points in the ET group (p < 0.001). According to the Good rating system, 43 patients in the AR group had good or excellent results compared with 15 in the ET group (p < 0.001). Compared with anatomical reconstruction, the Evans tenodesis does not prevent laxity in a large number of patients. Long-standing ligamentous laxity leads to degenerative change in the ankle, resulting in chronic pain, limited dorsiflexion and further operations. The functional result deteriorates more rapidly after the Evans tenodesis than after anatomical reconstruction

Tibiotalar fusion is considered to be the standard treatment for end-stage post-traumatic arthritis of the ankle. We report a retrospective, objective long-term study of the quality of life of 17 patients with 18 arthrodeses of the ankle, over a period of more than 20 years. We looked particularly for correlation between clinical and radiological signs of osteoarthritis in adjoining joints. At serial physical examinations, clinical grades were awarded according to the Olerud Molander Ankle (OMA) score. Any degree of degenerative change in the adjoining joints was recorded on standing radiographs. Patients filled out a SF-36 Health Survey form. Subjectively, 50% of patients were not handicapped in the performance of daily activities and 44% were in the same job as at the time of injury. At follow-up the mean OMA score was 59.4 points, the visual analogue scale was 1.99 and the radiological score was 2.7. The SF-36 for physical function, emotional disturbance and bodily pain revealed significant deficits. There was a significant correlation between the OMA and the radiological score (p = 0.05), and between the clinical and the SF-36 score (p = 0.01), but no significant correlation between the radiological score and the SF-36 score. Arthrodesis of the ankle leads to deficits in the functional outcome, to limitations in the activities of daily living and to radiological changes in the adjoining joints. The clinical outcome score correlates closely with the SF-36 score
