Feasibility of an at Home, Online, Yoga-Based and Standard Exercise Intervention for Rotator Cuff Injuries

Exercise has been shown to benefit RC patients in terms of reducing pain, improving strength, ROM and function.3 However, clinical studies have primarily examined the role of traditional exercise for RC rehabilitation. The effects of yoga as exercise through an online home based setting have been scarcely investigated. This chapter will discuss the feasibility of a 6-week long exercise intervention. The purposes of this feasibility study were to:

Augmented Glenoid Replacement for Total Shoulder Arthroplasty

Degenerative arthritis resulting in asymmetric posterior glenoid wear presents management challenges for the treating surgeon. Factors that must be considered include the structural management of the bone deficiency, addressing posterior humeral head subluxation, and understanding the survivability of the various treatment techniques. Unfortunately, the literature to date is incomplete as it pertains to the long-term success rate of the various arthroplasty options for management of moderate to severe glenoid bone loss.

Two Bone Fragment Manipulation in Computer-Assisted Preoperative Planning: Restoration of the Radial Bow

Distal radius fractures are the most common fracture seen in hospital emergency departments. While most patients have a good outcome, a small percentage of fractures heal in a displaced position (malunion), which may cause pain, stiffness, and weakness of the wrist and forearm. We have developed a computer-assisted technique for correction (osteotomy) of distal radius malunion. Outcome studies have shown that this procedure is accurate, reliable, and safe. It has advantages over a computer-assisted conventional technique, including less fluoroscopic radiation to the patient and surgical team, and a quicker learning curve for non-expert surgeons. Our initial technique corrected only the initial fragment of the radius, leaving the proximal radius unchanged (relative to the ulna which is the fixed uninvolved element in the forearm in these cases). A new development reported here is the incorporation of correction of the proximal radius. This allows for full correction of the radial ulnar convergence, restoring the bow of the radius. We noted improved fixation plate positioning and full forearm rotation post operatively.
