KW - Reverse shoulder prosthesis
AB - Studies have analyzed three-dimensional complex motion of the shoulder in healthy subjects or patients undergoing total shoulder arthroplasty (TSA) or reverse shoulder arthroplasty (RSA). No study to date has assessed the reaching movements in patients with TSA or RSA. Twelve patients with TSA (Group A) and 12 with RSA (Group B) underwent kinematic analysis of reaching movements directed at four targets. The results were compared to those of 12 healthy subjects (Group C). The assessed parameters were hand-to-target distance, target-approaching velocity, humeral-elevation angular velocity, normalized jerk (indicating motion fluidity), elbow extension and humeral elevation angles. Mean Constant score increased by 38 points in Group A and 47 in Group B after surgery. In three of the tasks, there were no significant differences between healthy subjects and patients in the study groups. Mean target-approaching velocity and humeral-elevation angular velocity were significantly greater in the control group than in study groups and, overall, greater in Group A than Group B. Movement fluidity was significantly greater in the controls, with patients in Group B showing greater fluidity than those in Group A. Reaching movements in the study groups were comparable, in three of the tasks, to those in the control group. However, the latter performed significantly better with regard to target-approaching velocity, humeral-elevation angular velocity and movement fluidity, which are the most representative characteristics of reaching motion. These differences, that may be related to deterioration of shoulder proprioception after prosthetic implant, might possibly be decreased with appropriate rehabilitation.

Like the Reverse Shoulder Prosthesis, the RSP® Monoblock addresses severe shoulder arthritis and irreparable rotator cuff damage. However, the RSP® Monoblock also addresses complex upper arm fractures resulting from trauma.

DJO Surgical is the first company to offer blended vitamin e polyethylene in both the anatomic and reverse shoulder implant systems. Vitamin e is a naturally occurring anti-oxidant that has been shown to reduce the oxidative properties of the plastic component used in surgery. Along with reducing oxidation, the DJO Surgical e-plus has been tested to reduce long term wear by up to 92%.

Recovery of comfort and function after shoulder replacement continues for the first year after surgery. Adequate pain control is an important part of the postoperative management because it facilitates rehabilitation and allows recovery of motion. Immediately after surgery, strong medications (such as morphine) are often given by injection. Within a day or so, oral pain medications (such as as Percocet or Vicodin) are usually sufficient. These oral narcotic medications are generally only needed for a few weeks and patients are encouraged to wean off of them to regular Tylenol when sufficiently comfortable.
