Tendons are fascinating structures, but injuries to this tissue can be debilitating and lead to time off from dance. It has been reported that tendinopathy is one of the more prevalent musculoskeletal issues in ballet dancers 1. So, first off, what does a tendon injury consist of ? The term tendinopathy is now standard terminology used to describe a tendon when it becomes pathological usually with the distinguishing characteristics of pain, possible histological/tissue changes, decreased load tolerance and subsequent loss of participation in dancing activity. Currently, it’s thought that tendinopathy exists along a patho-etiological continuum. The original model proposed by Cook et al. describes stages of pathology based on pain, histological changes, and the functional limitations of the patient 2. The continuum model is a helpful guide to make appropriate decisions regarding rehabilitation strategies and interventions based on the individual and how they present.
Within the dancing population, the long tendons of the foot and ankle and the patellar tendon comprise the most common tendinopathies in females and males respectively. A higher incidence of peroneal and flexor hallucis longus (FHL) tendinopathy in the foot and ankle has been cited in ballet dancers 1, but the focus of this blog will be specifically on the FHL and posterior tibialis (PT) tendon. Both of these tendons run along the medial ankle and often considered in the differential diagnoses in a dancer presenting with medial ankle pain.
How do tendinopathies develop?
An acute spike in the physical activity and subsequent load through the tendon in a given day or over a period of time is a typical mechanisms of injury throughout all tendinopathies. An alteration in training remains consistent in the development of FHL and PT tendinopathy in the dancer population. Specific to the dance population, those who dance en pointe are thought to have a higher incidence of any foot or ankle injury 3. The FHL and PT are working harder to control foot and ankle when rising and lowering from flat to the en pointe position.
Other considerations involved with shoe wear as a contributing factor include switching pointe shoe makers, dancing in “dead shoes”, dancing in flat or character shoes.
Reports of intrinsic risk factors for PT tendinopathy exist. Biomechanical influences associated with anatomical variants, inherited or acquired systemic factors, and trauma are all intrinsic risk factors that can have an influence in the development of tendinopathy 4,5
1. Advice and Education
Guiding the dancer in any modifications they need to make to their dance activity needs to be done to manage their acute phase of pain. Advice on activity restrictions will differ from a dancer with tendinopathy who needs to take time off to those dancers who are still expecting or are expected to perform. The latter situation may be more complex and involve coordinating with other members of the dance company. Specific strategies regarding optimal loading and activity are usually best made on an individual basis as many factors are considered.
A “winged” position (plantar flexion, abduction and eversion) of the foot may predispose the FHL/PT tendon to increased strain as this places the tendon in a lengthened position 4. This position can especially compromise the FHL and PT at the ankl
