Background: The purpose of this study was to evaluate the usefulness and safety of the anterosuperior deltoid splitting approach for fixation of displaced proximal humeral fractures by analyzing the surgical outcomes. Methods: Twenty-three patients who could be followed-up for at least 8 months after the treatment of displaced proximal humeral fractures through the anterosuperior deltoid splitting approach were enrolled. We evaluated the reduction of the fractures and surgery-related complications at the last follow-up using X-ray results and clinical outcomes comprising the University of California at Los Angeles (UCLA) scoring system and the Korean Shoulder Society (KSS) score. Results: At the last follow-up of patients treated using the anterosuperior deltoid splitting approach for internal fixation of proximal humeral fractures, we found 22 cases (95.6%) of bone union, a mean UCLA score of 28.3 (range, 15 to 34) and a mean KSS score of 82.1 (range, 67 to 95). Various surgery-related complications were noted; a case of varus malunion after fracture displacement, a case of nonunion, a case of delayed union, two cases of impingement, and a case of partial axillary nerve injury, which recovered completely through the follow-up. Conclusions: Plate fixation using the anterosuperior deltoid splitting approach could be another reliable option for treating displaced proximal humeral fractures.

목적: 삼각근 분할 도달법 또는 삼각 대흉간 도달법을 이용하여 잠김 압박 금속판 고정 술을 실시한 근위 상완골 골절의 환자에서 방사선학적, 임상적 결과를 비교 분석하였다. 대상 및 방법: 근위 상완골 불안정성 골절로 잠김 압박 금속판을 이용한 골절의 정복 및 고정술을 실시한 75명의 환자를 대상으로, 평균 38.2주의 추시를 하였으며 각 군에서 수술 후 상완골의 경간각의 변화를 방사선학적 결과로 측정하고, 기능적 결과로 KSS 및 Constant score 차이를 측정하여 비교 분석하였다. 결과: 수술 도달법에 따른 방사선학적 결과에서 상완골 경간각의 차이는 삼각근 분할 도달법에서 평균 12.04도와 삼각 대흉간 도달법에서 평균 10.20도로 통계학적으로 유의한 차이는 없었다. 기능적 결과에서 KSS의 차이와 Constant score의 차이는 삼각근 분할 도달법이 22.74점 및 13.78점으로 삼각 대흉간 도달법의 31.13점과 19.41점보다 우수한 결과를 보였다. 결론: 불안정한 근위 상완골 골절의 치료에서 삼각근 분할 도달법을 통한 골절의 정복과 잠김 압박 금속판을 사용한 고정술이 기능적인 결과의 회복에 더 효과적일 것으로 사료된다.

Background: This study introduces a surgical technique with good clinical outcome useful in the treatment of osteoporotic displaced 3- or 4-part proximal humeral fractures. Methods: From May 2014 to February 2016, 16 patients with displaced 3- or 4-part proximal humeral fractures were treated by application of a locking plate with an endosteal strut allograft via a deltoid splitting approach with a minimum follow-up of 12 months. The allograft was inserted through a fractured gap of the greater tuberosity to support the humeral head and then fixed by a locking plate with meticulous soft tissue dissection to protect the axillary nerve. Surgical outcomes were evaluated by the American Shoulder and Elbow Surgeons (ASES) and visual analogue scale (VAS) scores, radiological imaging, and clinical examination. Fixation failure on radiographs was defined as a >$5^{\circ}$ loss of neck shaft angle (NSA) compared to that on an immediate postoperative radiograph. Avascular necrosis (AVN) of the humeral head was also evaluated. Results: In all cases, complete union was achieved. The ASES and VAS scores were improved to $85.4{\pm}2.1$ and $3.2{\pm}1.3$, respectively. Twelve patients (75.0%) had greater than a $5^{\circ}$ change in NSA; the average NSA change was $3.8^{\circ}$. Five patients (31.3%) had unsatisfactory ranges of motion exhibiting a <$100^{\circ}$ active forward flexion. No axillary nerve injuries or AVN were observed at the last follow-up. One patient was converted to reverse total arthroplasty due to severe pain and functional deficit. Conclusions: Minimally invasive fixation via a locking compression plate and an endosteal fibula strut allograft in Neer classification 3-or 4-part fractures with severe osteoporosis in elderly patients can achieve good clinical results.
