Cementless surface replacement arthroplasty (Copeland CSRA) for osteoarthritis of the shoulder.
Clinical experience with the Copeland cementless surface replacement arthroplasty (CSRA) of the shoulder now spans 17 years. Between 1986 and 1997, 79 CSRAs (42 total shoulder replacements and 37 hemiarthroplasties) were performed for primary osteoarthritis of the shoulder. Total shoulder replacement was done in 12 men and 30 women with a mean age of 71.5 years (range, 50-87 years). ⋯ With use of the CSRA prosthesis, several severe complications mainly concerning the humeral shaft and periprosthetic fractures can be avoided. Should the need for revision surgery or arthrodesis arise, these procedures are easily performed, as bone stock has been maintained and no loss of length has been encountered. It does seem that the humeral component does not need a stem or cement for fixation.

Entrapment of the long head of the biceps tendon: the hourglass biceps--a cause of pain and locking of the shoulder.
We describe an unrecognized mechanical condition affecting the long head of the biceps (LHB) tendon with entrapment of the tendon within the joint and subsequent pain and locking of the shoulder on elevation of the arm. We identified 21 patients with a hypertrophic intraarticular portion of the LHB tendon during open surgery (14 patients) or arthroscopic surgery (7 patients). All cases but one were associated with a rotator cuff rupture. ⋯ Simple tenotomy cannot resolve this mechanical block. Excision of the intraarticular portion of the LHB tendon, during bipolar biceps tenotomy or tenodesis, must be performed. The hourglass biceps is an addition to the familiar pathologies of the LHB (tenosynovitis, prerupture, rupture, and instability) and should be considered in cases of shoulder pain associated with a loss of elevation.
