Axillary artery and brachial plexus injury secondary to proximal humeral fractures: A report of 2 cases.

Axillary artery and brachial plexus injuries have been reported to be associated with proximal humeral fractures. In this report, we present two cases of axillary artery and brachial plexus injury secondary to proximal humeral fracture.

Hemiarthroplasty for proximal humerus fractures with conservation of the whole humeral head as autograft: does it improve greater tuberosity healing?

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.

A comparative study of proximal femoral locking compress plate, proximal femoral nail antirotation and dynamic hip screw in intertrochanteric fractures.

We aimed to compare the clinical efficacy of three different internal fixation methods, i.e. proximal femoral locking compress plate (PF-LCP), proximal femoral nail antirotation (PFNA) and dynamic hip screw (DHS) system in intertrochanteric femur fracture.

Reverse Shoulder Arthroplasty in Recent Proximal Humerus Fractures.

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 shou...

Regional variations of cortical bone in the humeral head region: A preliminary study.

Incidence of proximal humeral fractures dramatically increased over the last decade due to demographic changes. The goal of this study was to analyze regional characteristics of cortical bone in the humeral head region using cortical bone mapping (CBM) technique.

Comparative Study of Two Surgical Techniques for Proximal Adjacent Segment Pathology after Posterior Lumbar Interbody Fusion with Pedicle Screw: Fusion Extension using Conventional Pedicle Screw versus Cortical Bone Trajectory-Pedicle Screw (Cortical Screw).

To present a minimally-invasive surgical technique using cortical bone trajectory-pedicle screw (cortical screw, CS) for adjacent segment pathology (ASP) after lumbar fusion surgery, and to thoroughly compare postoperative outcomes of the two surgical techniques with either CS or conventional pedicle screw (PS) for ASP in one year follow-up time.

Decision Making in the Management of Extracapsular Fractures of the Proximal Femur - is the Dynamic Hip Screw the Prevailing Gold Standard?

Currently, approximately half of all hip fractures are extracapsular, with an incidence as high as 50 in 100,000 in some countries. The common classification systems fail to explain the logistics of fracture classification and whether they all behave in the same manner. The Muller AO classification system is a useful platform to delineate stable and unstable fractures. The Dynamic hip screw (DHS) however, has remained the 'gold standard' implant of choice for application in all extracapsular fractures. The ...

Fragility fractures of the proximal femur: review and update for radiologists.

Proximal femoral fragility fractures are common and result in significant morbidity and mortality along with a considerable socioeconomic burden. The goals of this article are to review relevant proximal femoral anatomy together with imaging, classification, and management of proximal femoral fragility fractures, and their most common complications. Imaging plays an integral role in classification, management and follow-up of proximal femoral fragility fractures. Classification of proximal femoral fragility...

Humeral Bone Loss in Revision Shoulder Arthroplasty.

Revision shoulder arthroplasty is becoming more prevalent as the rate of primary shoulder arthroplasty in the US continues to increase. The management of proximal humeral bone loss in the revision setting presents a difficult problem without a clear solution. Different preoperative diagnoses often lead to distinctly different patterns of bone loss. Successful management of these cases requires a clear understanding of the normal anatomy of the proximal humerus, as well as structural limitations imposed by s...

Traditional manipulative reduction and percutaneous elastic intramedullary nail fixation for the treatment of proximal humeral fractures in children.

To study clinical effects and safety of traditional manipulative reduction and percutaneous elastic intramedullary nail fixation for the treatment of proximal humeral fractures in children.

Humeral shaft fractures.

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 tec...

Correlation between femoral offset loss and dynamic hip screw cut-out complications after pertrochanteric fractures: a case-control study.

Screw-plates disassembly incidence after pertrochanteric fracture (PF) amounts to 1 and 16% among the elderly population. The main occurrence is early cervical screw cut-out. The population at highest risk of disassembly remains difficult to identify. The correlation between femoral offset loss and disassembly occurrence has never been surveyed.

Treating Humeral Bone Loss in Shoulder Arthroplasty: Modular Humeral Components or Allografts.

Reconstructing proximal humeral bone loss in the setting of shoulder arthroplasty can be a daunting task. Proposed techniques include long-stemmed humeral components, allograft-prosthesis composites (APCs), and modular endoprosthetic reconstruction. While unsupported long-stemmed components are at high risk for component loosening, APC reconstruction techniques have been reported with success. However, graft resorption and eventual failure are significant concerns. Modular endoprosthetic systems allow bone ...

Humeral Fractures Sustained During Arm Wrestling: A Retrospective Cohort Analysis and Review of the Literature.

Arm wrestling places significant torque on the humeral shaft. A spiral distal humeral shaft fracture is an unusual but significant injury that can result. Of 93 patients who presented between 2009 and 2017 with closed humeral shaft fractures that were managed nonoperatively, 9 sustained the fractures while arm wrestling. Outcomes were compared with those of all other patients with nonoperatively managed humeral shaft fractures sustained through other mechanisms. The Student's t test was used to compare coho...

A Novel Method for the Approximation of Humeral Head Retrotorsion Based on Three-Dimensional Registration of the Bicipital Groove.

The accurate restoration of premorbid anatomy is key for the success of reconstructive surgeries of the proximal part of the humerus. The bicipital groove has been proposed as a landmark for the prediction of humeral head retrotorsion. We hypothesized that a novel method based on bilateral registration of the bicipital groove yields an accurate approximation of the premorbid anatomy of the proximal part of the humerus.

Internal Rotation Traction Radiograph Improves Proximal Femoral Fracture Classification Accuracy and Agreement.

The objective of this study is to assess the clinical utility of internal rotation traction radiography in the classification of proximal femoral fractures.

A Biomechanical Comparison of Three Inferiorly-Directed vs. Three Superiorly-Directed Locking Screws on Stability in a 3-Part Proximal Humerus Fracture Model.

To quantify the stability of 3 points of inferiorly-directed versus 3 points of superiorly-directed locking screw fixation compared to the full contingent of 6 points of locked screw fixation in the treatment of a 3-part proximal humerus fracture.

Titanium mini locking plate with trans-osseous sutures for the treatment of humeral greater tuberosity fracture osteosynthesis versus PHILOS: a retrospective view.

Greater tuberosity fractures (GTFs) account for 17 to 21% of proximal humerus fractures, most of these fractures are treated conservatively, but treatment for displaced fractures is still controversial. The aim of this study is to compare intra-operative clinical conditions and post-operative outcomes when displaced GTFs are treated with either proximal humeral internal locking system (PHILOS) or mini locking plate with trans-osseous sutures.

Proximal Humerus Fracture 3-D Modeling.

The objective of this study is to determine the reproducibility and feasibility of using 3-dimensional (3-D) computer simulation of proximal humerus fracture computed tomography (CT) scans for fracture reduction. We hypothesized that anatomic reconstruction with 3-D models would be anatomically accurate and reproducible. Preoperative CT scans of 28 patients with 3- and 4-part (AO classification 11-B1, 11-B2, 11-C1, 11-C2) proximal humerus fractures who were treated by hemiarthroplasty were converted into 3-...

Total Shoulder Arthroplasty Using a Bone-Sparing, Precision Multiplanar Humeral Prosthesis.

Proper reconstruction of proximal humeral anatomy is of primary importance to maximize patient outcomes after total shoulder arthroplasty. This article describes a new arthroplasty technique, where a fixed multiplanar bone resection is made and a novel implant, which is designed to precisely match the bone resection, is inserted.

Surgical Technique: Anterolateral Approach to the Humerus.

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.

An analysis of proximal humerus morphology with special interest in stemless shoulder arthroplasty.

Shoulder arthroplasty evolution has resulted in the shortening of traditional stemmed humeral components. Newer stemless implants rely on structures that maintain fixation in the metaphyseal region of the proximal humerus. Whereas the overall morphology of the proximal humerus is well understood, the advent of stemless implants requires that additional geometric measures be assessed. This study's purpose was to introduce new anatomic measures to assist with the design of stemless implants.

CORR Insights®: Do Early Results of Proximal Humeral Allograft-Prosthetic Composite Reconstructions Persist at 5-year Followup?

A novel C2 screw trajectory: Preliminary anatomical feasibility and biomechanical comparison.

Pedicle screw and translaminar screw fixation in C2 may not be applicable in many patients with anatomical abnormalities or narrow laminar thickness and spinous process height. The objective of the current study was to assess the morphometric and mechanical feasibilities of a novel alternate C2 screw trajectory.

Reliability of the Anterior Humeral Line Index Compared With the Gartland Classification for Posteriorly Hinged Supracondylar Humerus Fractures.

The Gartland classification of pediatric supracondylar humerus (SCH) fractures is commonly used but inconsistently defined regarding type 1 and type 2 (posteriorly hinged) SCH fractures. This study examined the reliability of the anterior humeral line (AHL) index compared with the Gartland classification. Fifty consecutive SCH fractures on anteroposterior and lateral elbow radiographs in pediatric patients (age range, 18 months to 15 years) were classified by 11 observers (9 attendings and 2 residents) acco...
