Incidence of calcaneal fractures
▪ Calcaneal fractures account for 2% of all fractures
▪ Calcaneal fractures responsible for 60% of major tarsal injuries
▪ The friction between tendon and surrounding structure during the motion of ankle joint will result in tenosynovitis in the sheaths.
The purpose of our study
Measurement of the calcaneal width
▪ The maximum width of each calcaneus at the sustentaculum tali level was measured on the coronal section of CT images
▪ To verify the hypothesis by adapting the imaging technique of peroneal tenography
▪ To explore in depth of the correlation between lateral calcaneal pain, calcaneal width and peroneal tendon sheath impingement
▪ 74 patients with unilateral calcaneal pain were located from the trauma registry from March 2006 to October 2008.
▪ 57 males and 17 females ▪ average age: 39 years (17 to 72 years) ▪ 46 left feet and 28 right feet ▪ 43 cases treated with open reduction and
▪ The lateral calcaneal pain, as one of the most common sequelae, remains a challenge to the orthopaediac surgeons.
Hypothesis
▪ A hypothesis is that the calcaneus becomes wider during fracture healing which will cause compression of the peroneal tendon sheath.

Peroneal Tenography
▪ Bilateral peroneal tenography was performed to examine compression on the peroneal tendon sheaths

▪ Patients who have significant lateral calcaneal pain secondary to calcaneal fracture were included in the study.
Statistical analysis
▪ Performed using SPSS 13.0 for Windows.
▪ The correlation among lateral calcaneal pain, increasing calcaneal width and peroneal tendon sheath impingement was analyzed with bivariate correlation(spearman's rank correlation).
internal fixation ▪ 31 cases managed with closed reduction with
percutanous fixation and casting
▪ The mean duration from operation on the calcaneal fracture to the occurrence of lateral calcaneal pain was 4.7 months (ranged from 2.5 months to 11 months).
▪ 80-90% cases occur in young and adults
Backgroud
▪ Patients who sustain calcaneal fracture especially dislocated intra-articular calcaneal fracture often suffer chronic sequelae at follow-ups.
