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.

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%.

Shoulder arthroplasty & Physiotherapy - SlideShare

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.

Revision surgery due to weakness

The early recovery period focuses on maintaining the range of motion achieved by release of scar tissue during the surgery. Strengthening exercises are not performed for the first 6 weeks to prevent stress on the tendon repair. A sling is worn between exercise sessions for the first month and then may be discontinued. Patients may use the hand for holding objects like a cup of coffee or newspaper but nothing more than 1-2 lb. By 6 weeks, gentle active use of the arm for daily activities may be resumed but no heavy lifting, pushing or pulling is allowed. Therapy focuses on a continued flexibility program with aim of a progressive return to full range of motion. Muscle re-education begins with light resistance exercises for the rotator cuff and the muscles that stabilize the shoulder blade.

Recovery of mobility, strength and function is a graduated process that follows tissue healing. We have developed comprehensive therapy protocols that are designed to prevent recurrent stiffness and re-educate the muscles about the shoulder girdle to function in a smooth and coordinated fashion. These protocols are designed in such a way for the therapist to educate the patients about home exercises throughout the recovery process. The exercises that a patient does on his/her own between therapy sessions are equally as important as the sessions themselves, and patient adherence to this program is critical to preventing early stiffness. A properly performed home exercise program ensures that the exercises are done frequently, effectively and comfortably.

Reverse Shoulder Replacement - Orthosports

Patients generally remain in the hospital for 2-4 days following shoulder replacement surgery. Criteria for discharge either to home or to a rehabilitation hospital include:
1. a clean and dry incision without signs of infection
2. normal bowel and bladder function
3. adequate pain relief with oral pain medications
4. ability to properly perform and comply with home range of motion exercise program
5. adequate support to ensure patients are safe if going back to the home environment
