BACKGROUND: Fixation of proximal humeral fractures (PHF) with locking plates has gained popularity over conservative treatment, but surgery may be complicated with infection, non-union, avascular necrosis (AVN) of the humeral head and fixation failure. Failure to achieve structural support of the medial column has been suggested to be an important risk factor for fixation failure. The aims of this study were to examine the effect of calcar screws and fracture reduction on the risk of fixation failure and to assess long-term shoulder pain and function...

Proximal humerus fractures involving an articular head split are rare and complex injuries. In the elderly population, arthroplasty is the optimal treatment, while in younger patients, the utility of arthroplasty procedures are limited by concerns of long-term implant survival. As a result, open reduction and internal fixation (ORIF) is still often the first-line treatment option for head splitting injuries. The traditionally described deltopectoral or anterolateral surgical approaches to the proximal humerus rely on indirect reduction and limited visualization of the articular fragments...

BACKGROUND: Our purpose was to evaluate the clinical and radiologic outcomes of reverse shoulder arthroplasty for proximal humeral fractures in a large cohort of elderly patients and compare the results in the case of tuberosity excision, failed fixation, or anatomic healing. METHODS: In this retrospective multicenter study, 420 patients underwent review and radiography with a minimum follow-up period of 12 months. The patients were divided into 3 groups according to the status of the greater tuberosity (GT) on the last anteroposterior radiographs: anatomic GT healing (group A, n = 169); GT resorption, malunion, or nonunion (group B, n = 131); and GT excision (group C, n = 120)...

PURPOSE: We aimed to biomechanically evaluate the effect of the supraspinatus tendon on tuberosity stability using two different reverse shoulder arthroplasty (RSA) models for complex proximal humeral fractures (PHFs). METHODS: Four-part proximal humeral fractures were simulated in 20 cadaveric shoulders. Two different RSA designs were implemented: a glenosphere-medialized model and a glenosphere-lateralized model. Tuberosities were reconstructed, and displacement of bony fragments was measured (mm) by placing three sensors: in the humeral diaphysis (D), in the greater tuberosity (GT), and in the lesser tuberosity (LT)...

INTRODUCTION: Reverse shoulder arthroplasty (RSA) is a key tool in the orthopedic trauma surgeon's arsenal, especially when faced with a proximal humerus fracture in older patients. However, few studies have focused on the glenoid side of RSA in this indication as the implant is placed in a generally healthy scapula. HYPOTHESIS: Glenoid implants for RSA after trauma are well positioned and do not often cause complications. MATERIAL AND METHODS: Retrospective multicenter study of 513 patients who underwent RSA because of a proximal humerus fracture...

There is still no gold standard for the treatment of humeral shaft fractures. This might be attributed to the fact that several commonly used treatment methods have shown good clinical results. A bimodal age distribution of humeral shaft fractures with frequency peaks between 20 and 30 years old and above 60 years old is reported. Decision making for conservative or operative treatment depends not only on the injury pattern but is also dependent on individual patient needs. Currently available operative techniques include antegrade and retrograde interlocking medullary nailing as well as the use of longer proximal humeral nails...

BACKGROUND: Treatment of proximal humerus fractures with locking plates is associated with complications. We aimed to compare the biomechanical effects of removing screws and blade of a fixed angle locking plate and hybrid blade plate, on a two-part fracture model. METHODS: Forty-five synthetic humeri were divided into nine groups where four were implanted with a hybrid blade plate and the remaining with locking plate, to treat a two-part surgical neck fracture...

INTRODUCTION: Diaphyseal fractures with proximal humeral extension can be treated using a helical model, so it is lateral on the proximal aspect and on the diaphyseal segment in the anterior surface. OBJECTIVE: Our objective was to evaluate possible rotational deviations using minimally invasive plate osteosynthesis (MIPO) and to determine how it affects upper limb function. METHODS: We followed 11 patients for a period of two years. The proximal approach was anterior-lateral, and the distal approach was anterior, dividing the brachial muscle...

Reverse shoulder arthroplasty is now the standard treatment for displaced, three- or four-part, proximal humeral fractures in patients older than 70 years. Inadequate tuberosity repair or inappropriate humeral stem position are associated with poorer outcomes, notably regarding rotation and stability. Strict operative technique during prosthesis implantation is therefore crucial to obtain reliable and reproducible outcomes. The objective of this article is to describe the surgical technique for reverse shoulder arthroplasty used to treat recent proximal humerus fractures...

Aims: Plating displaced proximal humeral fractures is associated with a high rate of screw perforation. Dynamization of the proximal screws might prevent these complications. The aim of this study was to develop and evaluate a new gliding screw concept for plating proximal humeral fractures biomechanically. Methods: Eight pairs of three-part humeral fractures were randomly assigned for pairwise instrumentation using either a prototype gliding plate or a standard PHILOS plate, and four pairs were fixed using the gliding plate with bone cement augmentation of its proximal screws...

BACKGROUND: Locking plate fixation appears to be a standard treatment for proximal humeral fracture. Different locking plate designs might result in different radiographic and functional outcomes. The original version of the Proximal Humeral Internal Locking System (PHILOS; DePuy Synthes, Warsaw, IN, USA) occupied the largest volume of the humeral head by screw distribution, whereas the Zimmer Periarticular Locking Plate (ZPLP) system (Zimmer Biomet, Warsaw, IN, USA) occupied the smallest...

PURPOSE: Hemiarthroplasty (HA) for proximal humerus fracture (PHF) is associated with tuberosity complications like migration, non-union, and resorption. In order to improve the rate of consolidation of the greater tuberosity (GT), we have developed a hollow humeral head prosthesis in which the whole humeral head is inserted and used as autograft. This study is designed to evaluate the consolidation rate of the GT with this device. METHOD: Twenty-two patients at mean age of 68 were treated between 2015 and 2017 for four-part fractures, fracture-dislocations, and head-split fractures with HA including the bony humeral head...

INTRODUCTION: Although most humeral shaft fractures can be treated nonoperatively, many patients do benefit significantly from surgical treatment. The anterolateral approach to the humerus provides excellent exposure to the humeral shaft, especially to more proximal aspects. In addition, the approach can be extended both proximally and distally, providing the surgeon a dynamic exposure to the humerus for the treatment of fractures and other pathologies. METHODS: This video highlights a clinical case where a mid-shaft humerus fracture was diagnosed and treated with open reduction internal fixation using an 8-hole 4...

BACKGROUND: Conversion to full-thickness tear in partial-thickness rotator cuff tears (PTRCTs) is based on the quality and thickness of the normal-looking untorn rotator cuff layer. However, whether the untorn tendon is a healthy tissue remains to be elucidated. PURPOSE: To compare the apoptotic gene expression of the untorn articular layer with the torn bursal layer in PTRCTs. STUDY DESIGN: Controlled laboratory study. METHODS: Tendon tissues were harvested from 20 patients undergoing arthroscopic surgery for partial-thickness rotator cuff repair...

Background: The aim of this study was to evaluate the clinical and radiographic results after minimally invasive plate osteosynthesis (MIPO) for proximal humerus fractures. Potential advantages of this approach include the easier exposure of the greater tuberosity and the limited surgical dissection around the fracture site. Materials and Methods: From October 2011 to March 2016, thirty-nine patients (32 women, 7 men) with a mean age of 64.9 years (range: 48-80) were surgically treated with the MIPO technique for proximal humeral fractures...

The aim of this study was to survey the incidence of osteoporotic fragility fractures, which include vertebral, hip, distal radius, and proximal humerus fractures, in patients ≥ 50 years of age, from 2004 to 2015, in Sado City, Japan. We examined temporal changes in the incidence of these fractures from 2010 through 2015. The incidence of vertebral (p < 0.001) and radius fractures (p = 0.001) was lower in 2015 than in 2010, with only the incidence of hip fracture (p = 0.013) being lower in 2015 than in 2004...

Interfragmental ischaemia is a prerequisite for the initiation of the inflammatory and immunological response to fracturing of bone.Intrafragmental ischaemia is inevitable: the extent of the initial ischaemic insult does not, however, directly relate to the outcome for healing of the fracture zones and avascular necrosis of the humeral head. The survival of distal regions of fragments with critical perfusion may be the result of a type of inosculation (blood vessel contact), which establishes reperfusion before either revascularization or neo-angiogenesis has occurred...
