A mistaken case of peroneal dislocation.
ABSTRACT This article is centred around the similarities and highlights some differences between a sports injury compared with any other injury profile. The authors use a musculoskeletal assessment, diagnosis and management of an injury based on a particular case study. The intention is to highlight how problems may be masqueraded in the history and perception of the injured athlete and how this perception may have complicated the injury and the rehabilitation process. This issue generates a renewed awareness for all primary care nurses and health practitioners who may be involved in treatment pathways for associated injuries related to sports medicine problems. The article gives an insight into peroneal dislocation/subluxation, but primarily focuses on peroneal tendonitis/tendonosis. The management of the injury briefly touches on the associated benefits (and risks) of barefoot running and its role in the prevention of sporting injuries. This article illustrates how the frustration of a chronic injury can lead to the athlete making ill-informed decisions and highlights the need for a thorough assessment and an evidence-based management plan that is negotiated with the athlete.

ABSTRACT: The objective of the study was to investigate the adjustment of running mechanics by wearing five different types of running shoes on tartan compared to barefoot running on grass focusing on the gearing at the ankle and knee joints. The gear ratio, defined as the ratio of the moment arm of the ground reaction force (GRF) to the moment arm of the counteracting muscle tendon unit, is considered to be an indicator of joint loading and mechanical efficiency. Lower extremity kinematics and kinetics of 14 healthy volunteers were quantified three dimensionally and compared between running in shoes on tartan and barefoot on grass. Results showed no differences for the gear ratios and resultant joint moments for the ankle and knee joints across the five different shoes, but showed that wearing running shoes affects the gearing at the ankle and knee joints due to changes in the moment arm of the GRF. During barefoot running the ankle joint showed a higher gear ratio in early stance and a lower ratio in the late stance, while the gear ratio at the knee joint was lower during midstance compared to shod running. Because the moment arms of the counteracting muscle tendon units did not change, the determinants of the gear ratios were the moment arms of the GRF's. The results imply higher mechanical stress in shod running for the knee joint structures during midstance but also indicate an improved mechanical advantage in force generation for the ankle extensors during the push-off phase.Journal of Biomechanics 05/2010; 43(11):2120-5. · 2.50 Impact Factor
