Thus, aiming for anatomic reconstruction can help to avoid negative consequences of component malpositioning (such as \u201coverstuffing\u201d) on soft-tissue tension and impingement-free range of motion.<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>\u27a2 The most common method to assess humeral head reconstruction is comparing the prosthetic humeral articular surface with the \u201cperfect circle\u201d incorporating the lateral cortex of the greater tuberosity, the medial greater tuberosity, and the medial calcar at the anatomic neck. Although this method is quick and helpful in assessing multiple parameters, it is important to also compare the radius of curvature, assess traditional measurements of humeral head anatomy or glenohumeral thickness, and consider that non-anatomic sizing may be used to achieve tension goals.<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>\u27a2 There is no consistent evidence of superior humeral head reconstruction quality with stemless, short-stem, or standard-length humeral components, suggesting that surgical technique and familiarity with an implant system remain most important.<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>\u27a2 Although stemless and short-stem components offer versatility in recreating pre-arthritic anatomy, their use places emphasis on having a reproducible technique for humeral neck osteotomy depth and inclination. Some techniques include careful osteophyte resection to visualize the true anatomic neck, the use of an intramedullary guide, and intraoperative assessment with fluoroscopy.<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>\u27a2 Although small deviations from pre-arthritic anatomy do not appear to affect clinical outcome, center-of-rotation deviations of exceeding 3 to 4 mm from the perfect circle have been associated with an inferior clinical outcome.<\/jats:p>\n                      <\/jats:list-item>\n                    <\/jats:list>\n                  <\/jats:p>","DOI":"10.2106\/jbjs.24.01583","type":"journal-article","created":{"date-parts":[[2026,1,7]],"date-time":"2026-01-07T16:00:27Z","timestamp":1767801627000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Humeral Head Reconstruction in Anatomic Shoulder Arthroplasty"],"prefix":"10.2106","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6262-3305","authenticated-orcid":false,"given":"Mihir M.","family":"Sheth","sequence":"first","affiliation":[{"name":"Anderson Orthopaedic Clinic, Arlington, Virginia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9774-1849","authenticated-orcid":false,"given":"Jason E.","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery and Sports Medicine, University of Washington Medical Center, Seattle, Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,12,1]]},"reference":[{"issue":"1","key":"bib1-20260311","doi-asserted-by":"crossref","first-page":"99S","DOI":"10.1016\/j.jse.2004.09.025","article-title":"Proximal humeral anatomy in shoulder arthroplasty: implications for prosthetic design and surgical technique","volume":"14","author":"Pearl","year":"2005","journal-title":"J Shoulder Elbow Surg."},{"issue":"2","key":"bib2-20260311","doi-asserted-by":"crossref","first-page":"209","DOI":"10.1016\/j.jseint.2021.11.013","article-title":"Extra-short humeral heads reduce glenohumeral joint overstuffing compared with short heads in anatomic total shoulder arthroplasty","volume":"6","author":"Monir","year":"2021","journal-title":"JSES Int."},{"issue":"4","key":"bib3-20260311","doi-asserted-by":"crossref","first-page":"555","DOI":"10.2106\/00004623-199504000-00008","article-title":"The effect of articular conformity and the size of the humeral head component on laxity and motion after glenohumeral arthroplasty.
