Brachial plexus birth palsy resolves spontaneously in a majority of patients, however, others may have serious permanent dysfunction. Although nerve transfers or grafts are early options for treatment, many children have residual deficits or present too late for such procedures. In these patients, rotational osteotomy of the humerus may restore improved function and motion. Unfortunately, traditional humeral osteotomies only provide correction in a single plane, therefore appropriate correction of the typical residual deformity is incomplete...

Lindley B Wall, Valeri Calhoun, Summer Roberts, Charles A Goldfarb
PURPOSE: In the amyoplasia type of arthrogryposis, a reverse pronated grasp pattern is often seen. We hypothesized that repositioning the hands, through distal humerus external rotation osteotomies (DHO), would allow for palm-to-palm grasp without arm cross-over and would improve function and parent/patient satisfaction. METHODS: The medical records of all patients treated surgically for arthrogryposis were reviewed at the Shriners Hospital for Children, St. Louis, MO...

BACKGROUND: An ideal animal model has always been the key to research the pathogenesis and treatment of adolescent idiopathic scoliosis (AIS), while available methods have obvious disadvantages. The deficiency of melatonin has been proved relating to AIS. In this research, we intended to apply Luzindole, the melatonin antagonist, in bipedal rat model, for the block of combination of melatonin and its receptor, to inhibit the melatonin effect, and then to understand whether this method can effectively improve the scoliosis rate of bipedal rat model, and investigate the role of melatonin in scoliosis...

PURPOSE: A chevron osteotomy of the ulna is widely used to obtain intra-articular access to the elbow in the treatment of type C distal humerus fractures. The trochlear notch of the proximal ulna is divided into 2 articular parts by the "bare area." Ideally, the olecranon osteotomy should be centered on the bare area to minimize damage to the joint cartilage. The goals of this study were to describe the anatomy of the bare area and design an ideal chevron-shaped osteotomy. METHODS: We dissected 38 cadaver elbows and measured the width of the bare area, the distance between the tip of the triceps insertion and the area on the olecranon cortex corresponding to the bare area...

PURPOSE: The treatment of intraarticular fractures of the distal humerus is challenging and involves the risk of complications and bad functional results. Anatomical and stable internal fixation with early postoperative mobilization is expected to improve the functional outcomes. The objective of this study was to evaluate the functional and radiological results, along with the complications associated, of open reduction and internal fixation using precontoured anatomical locking LCP plate system for intraarticular distal humerus fractures in adult patients...

PURPOSE: To assess the outcomes of the lateral para-olecranon triceps-splitting approach for the treatment of distal humeral fracture. METHODS: Ten patients (3 males, 7 females) with a mean age of 59 years were retrospectively reviewed. There were 2 A2, 3 C1, and 5 C2 fractures according to the AO/ASIF classification. Types B3 and C3 fractures were excluded from this study because the olecranon osteotomy approach was indicated to visualize the anterior fragment...

The implants used in reverse shoulder arthroplasty were originally designed for white patients; thus, they might not be optimal for smaller Asian patients. The selection of reverse shoulder arthroplasty systems is limited in Japan. The purpose of this study was to measure the geometry of the proximal humerus in elderly Japanese patients to inform implant selection according to humerus size. This study included 155 shoulders from 148 patients 50 years or older who underwent computed tomography for shoulder disorders other than arthritis and trauma...

To explore the techniques for mandibular reconstruction with composite free flaps and their outcomes, we systematically reviewed reports published between 1990 and 2015. A total of 9499 mandibular defects were reconstructed with 6178 fibular, 1380 iliac crest, 1127 composite radial, 709 scapular, 63 serratus anterior and rib, 32 metatarsal, and 10 lateral arm flaps including humerus. The failure rate was higher for the iliac crest (6.2%, 66/1059) than for fibular, radial, and scapular flaps combined (3.4%, 202/6018) (p<0...

INTRODUCTION: Cubitus varus is a most common repercussion of malunited supracondylar fracture of humerus in paediatric age group. Initially, valgus osteotomies were in trend, but due to higher rate of complications, these procedures are not in trends today, as they were earlier. Here, we are sharing our experience and results of reverse V osteotomy done for cubitus varus. MATERIAL AND METHOD: Reverse V osteotomy was done on 20 patients of cubitus varus (due to malunited supracondylar fracture of humerus)...

BACKGROUND: The most common sequela of neonatal brachial plexus palsy is an internal rotation contracture of the shoulder that impairs function and leads to skeletal deformation of the glenohumeral joint. Treatment options include release, transfers, and humeral osteotomy, all ultimately striving for better function through increased external rotation. Prior studies have shown that neonatal brachial plexus palsy alters humeral retroversion but with conflicting findings. We studied retroversion in children with internal rotation contractures from neonatal brachial plexus palsy to clarify its effect on version and surgical planning...

The majority of dislocated, intra-articular fractures are treated with an open reduction and internal fixation. In this paper we describe a variety of dorsal approaches to the distal humerus. Beside the dorsal approach through an olecranon osteotomy we also discuss the alternative dorsal approaches without osteotomy and their advantages and drawbacks. Moreover we discuss the preoperative planning and operative procedure. Early functional rehabilitation, without weight bearing, is important to achieve an optimal outcome...

BACKGROUND: Displaced intraarticular distal humerus fracture has been conventionally treated operatively with various triceps disrupting approaches. These approaches are associated with several complications, such as triceps weakness, nonunion or delayed union of osteotomy, implant prominence, and delayed mobilization of the elbow. We present the functional outcome of intraarticular distal humerus fracture fixation using a triceps-sparing paratricipital approach which allows early elbow mobilization and preserving triceps strength...

BACKGROUND: Distal humeral malunions are uncommon injuries, often associated with limited elbow motion, pain, instability, weakness, and sometimes ulnar neuritis. The complex anatomy of the elbow joint makes this condition one of the most complex elbow injuries to treat. MATERIALS AND METHODS: Four patients were treated by the same surgeon between 2011 and 2013 using a double-locking precontoured plating system for malunited intra-articular or extra-articular fractures of the distal end of the humerus...

Although intramedullary fixation is the standard form of surgical fixation of the long bones of children with osteogenesis imperfecta (OI), it remains fraught with complications. Implant breakage, implant cut out, long bone fracture, nonunion, and rod bending have all been described as complications of intramedullary long bone fixation in children with OI. Supplemental fixation techniques represent an attempt to decrease these risks of surgical implant failure of intramedullary devices. A supplemental plate and screw construct at a fracture or an osteotomy site in addition to an intramedullary device in the long bone segment is one such form of supplemental fixation...

AIMS: Cubitus varus is the most common late complication of a supracondylar fracture of the humerus in children. Correction can be performed using one of a number of techniques of osteotomy but each has disadvantages. We describe a new technique for correcting post-traumatic cubitus varus using a lateral closing wedge isosceles triangular osteotomy. PATIENTS AND METHODS: A lateral closing wedge isosceles triangular osteotomy was performed in 25 patients (15 male and ten female with a mean age of 9...

Background and purpose - The quality of pin fixation of displaced supracondylar humerus fractures in children has not been assessed, and the clinical value of radiographic examinations after pin fixation is unclear. We evaluated pin configuration, quality of osteosynthesis, and outcome in 264 supracondylar fractures. The clinical significance of postoperative radiographs was analyzed. Patients and methods - 252 Gartland-III and 12 flexion-type supracondylar humerus fractures were pin-fixed in the periods 2002-2006 and 2012-2014...

Transphyseal distal humerus fractures typically occur in children younger than 3 years secondary to birth trauma, nonaccidental trauma, or a fall from a small height. Prompt and accurate diagnosis of a transphyseal distal humerus fracture is crucial for a successful outcome. Recognizing that the forearm is not aligned with the humerus on plain radiographs may aid in the diagnosis of a transphyseal distal humerus fracture. Surgical management is most commonly performed with the aid of an arthrogram. Closed reduction and percutaneous pinning techniques similar to those used for supracondylar humerus fractures are employed...

This study reviewed the clinical history and management of acquired growth arrest in the upper extremity in pediatric patients. The records of all patients presenting from 1996 to 2012 with radiographically proven acquired growth arrest were reviewed. Records were examined to determine the etiology and site of growth arrest, management, and complications. Patients with tumors or hereditary etiology were excluded. A total of 44 patients (24 boys and 20 girls) with 51 physeal arrests who presented at a mean age of 10...
