Abstract
Purpose
The aims of this study were: (1) to define the incidence of tendinous injuries in calcaneus and pilon fractures with different fracture severity and (2) to determine the clinical impact of such injuries.
Study design and methods
CT-scans of 121 patients with calcaneus and pilon fractures were retrospectively analyzed over a 4-year period. The tendinous injuries were identified and correlated with the type of fracture (location and classification). Clinical analysis was performed using the American Orthopedic Foot and Ankle Society (AOFAS) and SF-36 (Short Form-36 Health Survey) scores.
Results
Tendinous injuries were observed in 36% of all CT-scans analyzed, with the most common injury being incarceration (n = 20) and dislocation (n = 24).
Calcaneus fractures sanders type 3/4 were 9 times more prone to tendon injury (p < 0.001; OR 8.67; 95% CI 2.49–30.24). Pilon fractures Ruedi–Allgower type 2/3 were 8 times more prone to tendon injury (p = 0.005; OR 7.5; 95% CI 1.72–32.80). No significant differences (p > 0.05) were found in AOFAS and SF-36 scores between patients with/without tendon injuries for fractures with the same severity.
Conclusion
The incidence of tendon injuries in calcaneus/pilon fractures is high and may be underreported. Calcaneus fractures are prone to peroneal tendon injury. In pilon fractures, it is important to look for tibialis posterior tendon injury, especially entrapment.
The presence of tendinous injuries does not affect function and pain for the same type of calcaneus and pilon fractures at the long term.
Level of Evidence
Level 3 retrospective study.
