REVIEW
David A Muzykewicz, Reid A Abrams
Anterior transhumeral radial nerve transposition has been described in the treatment of humeral shaft fracture to protect the nerve from implant irritation or callus entrapment. Transposing the radial nerve through a facilitating humeral defect also simplifies revision surgery should nonunion result. Here we describe a surgical technique for anterior transhumeral radial nerve transposition for complex humeral reconstruction when subsequent revision surgery is anticipated. Three cases are used for illustration: (1) revision of a total elbow arthroplasty with periprosthetic fracture; (2) revision of a total elbow arthroplasty after aseptic loosening from an allograft/prosthesis composite; and (3) septic humeral nonunion with substantial bone loss...

BACKGROUND: Fracture-dislocation is the extreme variant of injury to the proximal humerus that occurs more commonly in young adults as a result of high-velocity trauma. We evaluated the functional and radiologic outcome of fixation of proximal humeral fracture-dislocations with locked plates. METHODS: This was a retrospective review of 33 proximal humeral fracture-dislocations in 29 patients with a mean age of 35 years (range, 19-60 years) treated by open reduction and internal fixation with locked plates between January 2009 and December 2013...

INTRODUCTION: Supracondylar fractures are the most common elbow injuries in skeletally immature children between 5-10 years of age and cubitus varus deformity is the most common late complication. Cubitus varus or bow elbow or gunstock deformity is the result of malunion occurring as a complication of supracondylar fracture of the humerus. Various type of corrective osteotomies are used of which lateral closed wedge French osteotomy is commomly used which has its own complications like lateral condylar prominence, unsightful scar and limitation of movement...

Obstetric traumatic separation of the distal humeral epiphysis is a very uncommon injury, which presents a diagnostic challenge. These case serials reviewed the functional outcomes of 5 patients who had sustained a fracture-separation of the distal humeral epiphysis at birth. The diagnosis was made at a mean time of 40.8 h after delivery. All the patients were treated with gentle close manipulation, reduction under fluoroscopy and above-elbow cast application. After discharge, the patients were followed up for a mean of 30 months...

INTRODUCTION: Isolated greater tuberosity (GT) fractures (AO 11-A1) tend to occur in the younger patient population and are poorly managed by most precontoured proximal humerus locking plates. The goal of this study was to identify and assess an alternative treatment strategy for greater tuberosity fractures. MATERIALS AND METHODS: A retrospective review of all cases of isolated greater tuberosity fractures treated with a 2.4/2.7 mesh plate (Synthes) between 2010 and 2015 was conducted...

BACKGROUND: Comminuted fractures of the proximal humerus are generally treated with the locking plate system, and clinical results are satisfactory. However, unstable support of the medial column results in varus malunion and screw perforation. We designed a novel medial anatomical locking plate (MLP) to directly support the medial column. Theoretically, the combined application of locking plate and MLP (LPMP) would directly provide strong dual-column stability. We hypothesized that the LPMP could provide greater construct stability than the locking plate alone (LP), locking plate combined with a fibular graft (LPSG), and locking plate combined with a distal radius plate (LPDP)...

PURPOSE: Varus failure is one of the most common failure modes following surgical treatment of proximal humeral fractures. Straight antegrade nails (SAN) theoretically provide increased stability by anchoring to the densest zone of the proximal humerus (subchondral zone) with the end of the nail. The aim of this study was to biomechanically investigate the characteristics of this "proximal anchoring point" (PAP). We hypothesized that the PAP would improve stability compared to the same construct without the PAP...

Compression techniques seem to be the primary factor in determining the success of both plating and nailing techniques for the management of acute fractures and for delayed and nonunion management of these fractures. An intramedullary nail that can provide continual compression (like a plate) and mechanical manipulation of the callous throughout the course of treatment is an ideal device that provides all the advantages of plating and nailing and avoids the noted limitations of both. The UNYTE compression humeral nail is based on the PRECICE intramedullary limb lengthening system...

A healthy 71-day-old female Japanese Black calf was evaluated for fracture of the left humerus. The left humeral fracture was treated by closed repair and unilateral external skeletal fixation (ESF) with an epoxy putty fixator. The calf was active, and eight days after surgery slipped and fell, resulting in breakage of the ESF. The calf underwent repair by transfixation pinning and casting (TPC), which is an alternative to the ESF method. The TPC was removed 37 days after the first surgery, and the calf could bear weight on the left forelimb while walking...

BACKGROUND: Pink pulseless hand syndrome is a rare condition of vascular injury due to distal humerus fracture. It is characterized by radial and ulnar pulselessness in a complex of good hand perfusion which can remain pink and warm. The management and treatment of this condition is still very debated. METHODS: We report four cases of arm traumas which occurred in pediatric patients. In all cases, after the fixation of the fracture by the orthopedic surgeon, the clinical evaluation and duplex ultrasound demonstrated the so called "pink pulseless hand syndrome"...

Background: Low-trauma fractures of elderly women are a major public health concern. Methods: We determined the current trend in the absolute number and incidence (per 100,000 persons) of fresh low-trauma fractures of the proximal humerus among 80-year-old or older Finnish women by taking into account all women who were admitted to Finnish hospitals for primary treatment of such a fracture between 1970 and 2015. Results: The number of low-trauma fractures of the proximal humerus among 80-year-old or older Finnish women rose continuously between 1970 (32 fractures) and 2015 (568 fractures), whereas the age-adjusted fracture rate (showing a clear rise from 87 fractures per 100,000 persons in 1970 to 304 fractures in 1995) became stabilized between 1995 and 2015 (297 fractures per 100,000 persons in 2015)...

Humeral hemiarthroplasty, anatomic total shoulder arthroplasty, and reverse total shoulder arthroplasty all rely on a prosthetic articular surface fixed to the proximal humerus. Humeral implant designs have changed considerably as a result of improved understanding of proximal humeral anatomy and prosthetic biomechanics. Fixed, monoblock implants have been superseded by modular implants with variable inclination, offset, version, and stem length. Press-fit designs now commonly have surface coatings that allow bony ingrowth...

BACKGROUND: The FRAX algorithm estimates the 10-year probability of hip and major osteoporotic (clinical spine, forearm, hip, or humerus) fracture for adults aged 40 and over. An expert panel developed criteria to define elevated FRAX probabilities for U.S. adults aged 50 and over. This report uses FRAX estimates from the National Health and Nutrition Examination Survey 2013-2014 to describe the hip and major osteoporotic fracture probability distribution (for adults aged 40 and over) and prevalence of elevated probabilities (for adults aged 50 and over) in the United States...
