“…Sixth, our study met the often-used criterion of a minimum 2-year followup, however, it does not provide long-term followup data to assure the absence of delayed glenoid erosion or bony glenoid failure. However, Mercer et al [28] reported that medial migration of the humeral head after a ream and run procedure was less than 0.4 mm per year. We found that the ream and run procedure can improve centering of the humeral head on the glenoid in shoulders with the arthritic triad without altering glenoid version and with preservation of glenoid bone stock.…”

Background The arthritic triad of glenoid biconcavity, glenoid retroversion, and posterior displacement of the humeral head on the glenoid is associated with an increased risk of failure of total shoulder joint replacement. Although a number of glenohumeral arthroplasty techniques are being used to manage this complex pathology, problems with glenoid component failure remain. In that the ream and run procedure manages arthritic pathoanatomy without a glenoid component, we sought evidence that this procedure can be effective in improving the centering of the humeral head contact on the glenoid and in improving the comfort and function of shoulders with the arthritic triad without the risk of glenoid component failure.Questions/purposes We asked, for shoulders with the arthritic triad, whether the ream and run procedure could improve glenohumeral relationships as measured on standardized axillary radiographs and patient-reported shoulder comfort and function as recorded by the Simple Shoulder Test. Methods Between January 1, 2006 and December 14, 2011, we performed 531 primary anatomic glenohumeral arthroplasties for arthritis, of which 221 (42%) were ream and run procedures. Of these, 30 shoulders in 30 patients had the ream and run procedure for the arthritic triad and had two years of clinical and radiographic follow-up. These 30 shoulders formed the basis for this case series. The average age of the patients was 56 ± 8 years; all but one were male. Two of the 30 patients requested revision to total shoulder arthroplasty within the first year after their ream and run procedure because of their dissatisfaction with their rehabilitation progress. For the 28 shoulders not having had a revision, we determined on the standardized axillary views before and after surgery the glenoid type, glenoid version (90°minus the angle between the plane of the glenoid face and the plane of the body of the scapula), and location of the humeral contact point with respect to the anteroposterio dimension of the glenoid (the ratio of the distance from the anterior glenoid lip to the contact point divided by the distance between the anterior and posterior glenoid lips). We also recorded the patient's self-assessed shoulder comfort and function before and after surgery using the 12 questions of the Simple Shoulder Test. Results For the 28 unrevised shoulders the mean followup was 3.0 years (range, 2-9.2 years). In these patients, the ream and run procedure resulted in improved centering of the humeral head on the face of the glenoid (preoperative: 75% ± 7% posterior; postoperative: 59% ± 10% posterior; mean difference 16% [95% CI, 13%-19%]; p \ 0.001), notably this improved centering was achieved

“…This avoids excessive glenoid bone loss and also gives the humeral head a surface with a single concavity for joint contact. 16 Recent studies have shown that this technique is capable of improving pain and function in the short term for primary glenohumeral arthritis 17 , 18 and has also shown promising results in the management of the B2 glenoid. 19 The arthroplasty should be anatomic and not oversize the joint to prevent asymmetric loading.…”

Background: The biconcave (B2) glenoid is characterized by preservation of the anterior portion of the native glenoid with asymmetric wear of the posterior glenoid. Surgical options for glenoid correction have evolved. The goal of shoulder arthroplasty is to place the implants in such a manner to return the humeral head to a centered position and restore the joint line to a neutral position. There is no current consensus on method of treatment and correction. Methods: The current and historical literature on total shoulder arthroplasty was used to examine technique viability. Results: Asymmetric remaining can be used to address up to 15 of version correction without compromise of cortical bone. It is important to have the proper presurgical planning, to understand the limitations of correction, and to have other options available to treat the biconcave glenoid.

“…Replacement of the proximal humerus with a humeral component and conservative concentric glenoid reaming, without implantation of a glenoid component, removes the risk of glenoid component failure due to loosening [13,51]. This procedure has also been found to be effective in the treatment of GHOA and may be an effective option in younger patients in order to retain bone for future revision surgeries [13,[51][52][53]. In type B2 biconcave cases, conservative reaming to restore the glenoid to a single concavity, with the use of a humeral hemi-arthroplasty, may be an effective treatment for the arthritic triad [13].…”

The number of shoulder arthroplasty procedures has increased dramatically in recent years, with the primary indication being osteoarthritis (OA). Thus, morphology and subchondral bone changes associated with OA may be important factors to consider when choosing a replacement component. For surgical treatment, many implant options exist and survivability is often dependent on patient age, activity level, and progression of OA. In the placement of these replacement components, patient-specific guides now exist to improve component positioning, with the goal to improve long-term survivability by ensuring that intra-operative placement meets component design.
