“…These studies showed improvements in pain, function, and ROM at followup intervals similar to those of our patients [9,16,19,20,23,24]. These improvements are commensurate with our findings, in which pain score, forward elevation, external rotation, and internal rotation all improved by the final evaluation.…”

“…Early series were small but documented promising results. Weiss et al [24] showed, in a series of nine English-Macnab humeral components, one stem was loose at an average of 5 years' followup. McElwain and English [9] reported a similar rate of loosening at an average of 3 years postoperatively.…”

“…Early series with small numbers of patients had a radiographic loosening rate of approximately 10% at 3 to 5 years [9,24]. A larger series of 62 first-generation ingrowth stems confirmed this finding, with 9.7% of stems judged at risk at an average of 4.6 years' followup [20].…”

“…Several reports suggest reliable pain relief with long-term survivorship of 84% to 96% at 3.3 to 12.2 years [3,22,24]. However, as with all arthroplasties, complications, including infection, aseptic loosening, instability, and mechanical failure, present therapeutic challenges in longterm management of patients.…”

Background Cemented and uncemented stem types are available for TSA. An early uncemented stem designed for bone ingrowth had radiographic loosening of approximately 10% at intermediate followup (mean 4.6 years). Subsequent stem modifications included circumferential metaphyseal porous coating to enhance ingrowth and reduce loosening rates. Questions/purposes We asked whether the radiographic loosening rates would be lower after this design modification and whether the pain score and ROM would be improved. Patients and MethodsWe reviewed the medical records and radiographs of 76 patients undergoing primary TSA with circumferential metaphyseal porous-coated stems for osteoarthritis between 1995 and 2005. All patients had a complete standardized series of radiographs preoperatively, postoperatively, and at final followup. Humeral stems were evaluated for any radiolucent lines by zone, progression of lucencies, and shift in component position.The minimum radiographic followup was 25 months (average, 52 months; range, 25-90 months).

“…Treatments of arthritic glenohumeral joints depend largely on the condition of the rotator cuff (Bell et al, 1986;Torchia et al, 1997;Weiss et al, 1990). For those patients with intact/functional rotator cuffs, unconstrained prostheses remain the gold standard (Iannotti et al, 1992;Stewart and Kelly, 1997) achieving relief of pain, good function and range of motion.…”
