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.

Is distal locking screw necessary for intramedullary nailing in the treatment of humeral shaft fractures? A comparative cohort study.

The gold standard for intramedullary nailing (IMN) in humeral shaft fracture treatment is bipolar interlocking. The aim of this study was to compare clinical and radiographic outcomes in two cohorts of patients treated with IMN with or without distal interlocking. We hypothesized that there was no significant difference between isolated proximal interlocking and bipolar interlocking in terms of consolidation and clinical results.

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...

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.

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 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.

Proximal humeral fractures-Where do we stand today? : Comments on the "Proximal fracture of the humerus evaluation by randomization (PROFHER)" study.

The PROFHER study is a multicenter randomized controlled trial of 250 out of 1250 patients assessed for eligibility with dislocated proximal humeral fractures with involvement of the surgical neck. These patients were randomized either for surgery or conservative treatment. Patients with comorbidities that precluded surgery, lack of mental capacity, luxation fractures or clear indications for surgery from the authors' perspective were excluded. To evaluate the outcome, standardized self-assessment methods ...

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.

Atraumatic musculocutaneous neuropathy: A rare case caused by a proximal humeral bone spur.

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-...

Penetration and scattering-Two optical phenomena to consider when applying proximal remote sensing technologies to object classifications.

Proximal remote sensing is being used across a very wide range of research fields and by scientists, who are often without deep theoretical knowledge optical physics; the author of this article falls squarely in that category! This article highlights two optical phenomena, which may greatly influence the quality and robustness of proximal remote sensing: penetration and scattering. Penetration implies that acquired reflectance signals are associated with both physical and chemical properties of target objec...

Evaluation of the Accuracy of Pedicle Screw Insertion without Intraoperative Radiographic Guidance.

Three methods of pedicle screw insertion are in common use. Each has its advantages and disad-vantages and the decision to use a particular method depends on the type of procedure, indications, the patient's age, and the preferences and experience of the operator. The accuracy of screw insertion through the vertebral arch into the vertebral body may be assessed on post-operative CT or MRI and classified according to different systems. The free-hand method was analysed according to the Gertzbein classificati...

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.

Reverse total shoulder arhroplasty for the treatment of failed fixation in proximal humeral fractures.

This study evaluates the clinical outcomes in patients with proximal humerus fractures (PHF) treated with reverse total shoulder arthroplasty (RTSA) as a revision procedure for failed fixation that have more than 5 years of follow-up.

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

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...

Humeral Head Ossification Predicts Peak Height Velocity Timing and Percentage of Growth Remaining in Children.

Understanding skeletal maturity is important in the management of idiopathic scoliosis. Iliac apophysis, triradiate cartilage, hand, and calcaneal ossification patterns have previously been described to assess both peak height velocity (PHV) and percent growth remaining; however, these markers may not be present on standard spine radiographs. The purpose of this study was to describe a novel maturity assessment method based on proximal humeral epiphyseal ossification patterns.

Reverse shoulder arthroplasty in acute fractures of the proximal humerus: Does tuberosity healing improve clinical outcomes?

The study aimed to evaluate the clinical outcomes of reverse shoulder arthroplasty (RSA) in elderly patients with proximal humeral fractures and assess the role of tuberosity healing on the outcome.

Effect of the screw type (S2-alar-iliac and iliac), screw length, and screw head angle on the risk of screw and adjacent bone failures after a spinopelvic fixation technique: A finite element analysis.

Spinopelvic fixations involving the S2-alar-iliac (S2AI) and iliac screws are commonly used in various spinal fusion surgeries. This study aimed to compare the biomechanical characteristics, specifically the risk of screw and adjacent bone failures of S2AI screw fixation with those of iliac screw fixation using a finite element analysis (FEA).

Computational analysis on the feasibility of transverse iliosacral screw fixation for different sacral segments.

To evaluate the feasibility of transverse iliosacral (TIS) screw placement in different segments of the sacrum and measure the parameters of the unilateral iliosacral (IS) screw in the case that cannot be inserted the TIS screw.

Radiographic Study of Humeral Stem in Shoulder Arthroplasty After Lesser Tuberosity Osteotomy or Subscapularis Tenotomy.

Lesser tuberosity osteotomy (LTO) and subscapularis tenotomy (ST) are used for takedown of the subscapularis during shoulder arthroplasty. LTO offers the theoretical but unproven benefit of improved healing and function of the subscapularis. However, humeral stem subsidence and loosening may be greater when osteotomy is performed, which may compromise functional outcomes. Our hypothesis is that no difference in proximal collar press-fit humeral stem subsidence or loosening exists, with no impairment of func...
