Factors affecting results of patients with humeral proximal end fractures undergoing primary hemiarthroplasty: A retrospective study in 42 patients

Reverse shoulder arthroplasty versus hemiarthroplasty for acute proximal humeral fractures. A blinded, randomized, controlled, prospective study

“…In the HA group, this rate was similar to that observed by some authors 2,11 but less than the 80% to 96% reported in other studies. 13,27 In the RSA group, our rate was consistent with that of other studies. 7,15 Some authors 4,11 reported healing of tuberosities or integrity of rotator cuff as the main factor influencing the functional outcome after HA for proximal humeral fractures.…”

“…13,18,27 The functional outcome largely depends on the anatomic healing of the tuberosities, 4 but this healing is difficult in most elderly patients with comminuted fractures. 2 RSA has been proposed as an alternative treatment for these acute complex fractures 7,11 on the basis of the potential advantage that the functional results are less dependent on healing of the tuberosities and integrity of the rotator cuff, but this is still under assessment.…”

“…[25,26] Tüm bunlarla birlikte hastanın yaşı, cinsiyeti, ameliyat olana kadar geçen süre, rehabilitasyon zamanı fonksiyonel sonuçları etkileyen diğer önemli etkenlerdir. [27,28,29] Yüzeyel ya da derin enfeksiyon, dislokasyon, gevşeme, refleks sempatik distrofi, subakromial sıkışma, periprostetik kırık, tuberculum majus deplasmanına sekonder rotator cuff disfonksiyonu, heterotopik ossifikasyon ve aksiller sinir yaralanması hemiartroplastinin olası komplikasyonlarıdır. [21,24,26,30] Hemiartroplasti uyguladığımız 23 hastanın dokuzunda (%39.1) fizik muayenede rotator cuff yetmezliği saptadık.…”

Reverse Shoulder Arthroplasty for the Treatment of 3 and 4- Part Fractures of the Humeral Head in the Elderly

“…Other type of complications may include subacromial impingement, intraoperative or periprosthetic fractures, rotator cuff dysfunction secondary to tuberosity displacement and resorption and heterotopic ossification [26]. In combination with older age, implant malpositioning, increasing degree of tuberosity displacement, or even a persistent neurological deficit, these can lead to poor outcomes, creating the need for early re-operation and use of hemiarthroplasty for salvage of previous failed procedures [27, 28]. Failures due to improperly functioning rotator cuff often requiring additional surgery according to some long-term follow-up studies.…”
