Accreditation Check:

The growing need for a more efficient health delivery model is driving a greater number of direct referrals from primary care physicians to certified hand therapists. For that reason, hand therapists must be prepared to perform in-depth evaluations of the wrist and determine if conservative management is warranted prior to seeking surgical consult. The second part of the wrist instability series introduces an analysis of wrist instability based on six main features gathered from different classification systems. The course will discuss the movement of the radiocarpal and midcarpal joints and how it relates to the intricacy of wrist stability and its different components.

This is Part II of a three-part series.

1. Chronicity and Constancy

This chapter introduces the first two features assisting in the description of carpal instability. Chronicity refers to the temporal nature of injury and its effect on healing potential. Constancy elaborates on the severity of the ligamentous injury. Common ligamentous injuries are depicted and classified by gravity.

2. Etiology and Location

This chapter extends the description of carpal instability with the addition of features including etiology, considering the underlying disease or pathomechanics of injury and their particular location, allowing for an accurate identification of carpal partners and ligaments involved.

3. Direction and Pattern

This chapter concludes the carpal instability analysis features with the concepts of direction and pattern. The concept of direction will explain how the proximal row can be displaced and describe how dorsal and volar intercalated segmental instability (DISI and VISI) can spawn from midcarpal instability. The concept of pattern will identify the 4 different patterns of carpal instability and recall their defining characteristics.
