The purpose is to identify risk factors of functional outcome following proximal humerus open reduction and internal fixation. Patients treated for proximal humerus fractures with open reduction and internal fixation were enrolled in a prospective data registry. Patients were evaluated for function using the Disability of the Arm, Shoulder and Hand score for 12 months and as available beyond 12 months. Univariate analyses were conducted to identify variables associated with functional outcome. Significant variables were included in a multivariate regression predicting functional outcome...

Fractures are common traumatic injuries that mainly occur in the metaphyses of long bones such as the proximal humerus, distal radius, and proximal femur. However, most studies of fracture repair processes have focused on the diaphyseal region. In this study, we compared the bone repair processes of the metaphysis and the diaphysis of the mouse tibia. Bone apertures were formed in the tibial metaphysis and diaphysis. At indicated times after surgery, samples were collected, and the healing process was investigated using micro-computed tomography, as well as histological, immunohistochemical, and mRNA expression analyses...

Percutaneous osseointegrated (OI) implants for direct skeletal attachment of upper extremity prosthetics represent an alternative to traditional socket suspension that may yield improved patient function and satisfaction. This is especially true in high-level, transhumeral amputees where prosthetic fitting is challenging and abandonment rates remain high. However, maintaining mechanical integrity of the bone-implant interface is crucial for safe clinical introduction of this technology. The collection of population data on the transhumeral loading environment will aid in the design of compliance and overload protection devices that mitigate the risk of periprosthetic fracture...

OBJECTIVES: While osteoporosis has been shown to be a contributing factor in low energy fractures in the elderly, limited data exists regarding the correlation of bone mineral density (BMD) and T-Scores to mortality and failure of fracture fixation. This study seeks to determine the relationship between femoral neck BMD in elderly patients with typical geriatric fractures and mortality and fracture fixation failure using Quantitative Computed Tomography (QCT). MATERIALS AND METHODS: Patients over the age of 65 who sustained fractures of the proximal humerus, distal radius, pelvic ring, acetabulum, hip, proximal tibia, and ankle who also underwent a CT scan that included an uninjured femoral neck were retrospectively reviewed...

Valgus-impacted proximal humerus fracture is a classic but rare entity in shoulder traumatology. Surgical treatment is controversial, with increasing use of minimally invasive techniques. Our technique uses a minimally invasive approach under fluoroscopic control. Raising the humeral head to reduce the valgus enables spontaneous and well-positioned reduction of the tuberosities and screw fixation between the greater tuberosity and the humeral shaft. Indications comprise valgus-impacted fracture without comminution of the medial epiphyseal-metaphyseal hinge or greater tuberosity; the rotator cuff contributes to reduction and must be intact...

Introduction: Bilateral shoulder dislocations are rare and a diagnostic as well as a therapeutic challenge. Case Report: We report the case of a 67-year-old male who fell while skiing and suffered a bilateral anterior shoulder dislocation associated with a four-part proximal humerus fracture on the left side and an osseous avulsion of the rotator cuff, a Pulley lesion, and a Hill-Sachs lesion on the right side. In addition, we searched the PubMed database using the terms "bilateral shoulder dislocation" and also "bilateral glenohumeral dislocation"...

BACKGROUND: Several studies have reported that diabetic persons have an increased risk for fractures than non-diabetes patients. The association between proximal humerus fractures and type 2 diabetes (T2DM) is unclear and some studies point to insulin treatment, hypoglycaemic episodes consequently to inadequate control of diabetes or, more recently, to an alteration of trabecular bone. We examined trends in the incidence of proximal humerus fractures, surgical procedures and outcomes among hospitalized patients aged ≥65 years, with and without T2DM in Spain, 2001-2013...

Combination therapy using a BRAF and MEK inhibitor significantly improves both progression-free and overall survival in patients with BRAF V600-mutated stage IV melanoma. Dual MAPK inhibition achieves an objective response in the majority of patients. We present a case of a woman with BRAF V600E-mutated malignant melanoma and rapidly progressing liver, bone, and lymph node metastases. The patient commenced dabrafenib and trametinib with clinical and biochemical signs of response after 2 days. On day 3 she developed grade 3 liver hemorrhage, which was successfully embolized...

A proximal humerus fracture typically occurs when an elderly woman falls directly onto her shoulder or on her outstretched arm. Local pain in the shoulder and immobility of the upper arm raise a suspicion of a significant injury. Other bone and tendon injuries in the shoulder region as well as dislocation of the shoulder should be considered on differential diagnosis. Diagnosis is achieved by plain X-ray. Most fractures can be treated conservatively. Consultation with an orthopedist is needed, if there are several fracture fragments with extensive dislocation...

INTRODUCTION: Some patients with a hip fracture also present a concomitant upper limb fracture. We want to know whether these patients have a worse functional level and whether they have any differences in various clinical parameters compared with patients with an isolated hip fracture. MATERIAL AND METHODS: We retrospectively reviewed 1061 discharge reports from the Orthogeriatrics Unit. We collected information on several clinical parameters of the fractures. Subsequently, we performed a statistical analysis of the data by comparing the associated fracture group with the isolated fracture group...

BACKGROUND: The deltoid splitting approach has recently been widely adopted to facilitate less invasive procedures for proximal humerus fractures. However, there are still concerns regarding its effectiveness in aging people and in cases involving complex fractures. This study was conducted to evaluate the efficacy of a proximal humeral locking plate using the anterolateral deltoid splitting approach and to specifically examine the effect of patient age, gender, and fracture pattern on surgical outcomes...

Introduction: Treating peri-prosthetic fractures of the humerus can be very challenging, especially when there is poor bone stock and in the presence of adjacent joint prostheses. We discuss the option of a partial humeral replacement as a salvage procedure for such cases with some technical comments. Methods: This paper presents a technique which utilises a custom- made cemented connector to incorporate the existing well functioning elbow or shoulder replacement with a commercially available partial humeral replacement (PHR) or to an existing prosthetic humeral stem...

REVIEW
Aaron Andrew Frombach, Kendra Brett, Peter Lapner
Acute proximal humeral fractures in the elderly are generally treated non-operatively if alignment is acceptable and in stable fracture patterns. When operative treatment is indicated, surgical fixation is often difficult or impossible to obtain. Hemiarthroplasty has long been the standard of care. However, with its reliance on tuberosity healing, functional outcomes and patient satisfaction are often poor. Reverse shoulder arthroplasty has emerged as a new technology for treating proximal humeral fractures but the indications for its use remain uncertain...
