PURPOSE: Management of proximal humeral tumours remains a surgical challenge. No study to date has assessed the quality of life scores following the composite reverse shoulder arthroplasty for this indication. We, therefore, evaluated function and quality of life following reconstruction with allograft for malignant tumour of the humerus. METHODS: A series of six cases of humeral tumour treated by a single surgeon in a single centre was reviewed after a mean follow-up of 5...

BACKGROUND CONTEXT: The process of linear growth is driven by axial elongation of both long bones and vertebral bodies and accomplished by enchondral ossification. Differences in regulation between the two skeletal sites are mirrored clinically by the age course in body proportions. Whereas growth plates in long bones can easily be discriminated, vertebral growth plates are part of the cartilaginous endplate, which typically shows important species differences. PURPOSE: To describe and compare histological, histomorphometric and regulatory characteristics in the growth plates of the spine and long bones in a porcine model...

BACKGROUND: Adequate exposure of the proximal humerus is necessary to address atypical or complex proximal humerus fractures and orthopedic tumors. Surgical management may be difficult through existing approaches due to their limited nature and the delicate neurovascular anatomy of the shoulder. The deltoid lift, a previously described extensile approach, can be incorporated into the surgeon's armamentarium as an alternative exposure to the proximal humerus. The objective of this study was to quantify and compare the humeral exposure achieved through the deltoid lift with the standard direct lateral deltoid-splitting, anterolateral acromial, and deltopectoral approaches in terms of surface area and exposure of key anatomic landmarks...

Complex proximal humerus fractures in elderly patients represent a difficult problem for orthopaedic surgeons. Classically, treatment methods have included nonoperative management, open reduction and internal fixation, and hemiarthroplasty. Outcomes of nonoperative management for these complex fractures have been poor, and results of traditional operative techniques are variable at best. Over the past several years, reverse total shoulder arthroplasty (RTSA) has been increasingly employed in these injuries with encouraging results...

To clarify the cause of posterolateral rotatory instability after damage to the lateral ulnar collateral ligament (LUCL), the morphological characteristics of the LUCL were reinvestigated and three-dimensional (3D) image of the ligament was reconstructed using 35 human elbows. The results were as follows: 1) the insertion point of the LUCL on the humerus was almost at the center of the capitellum, and its width was 2.61 ± 1.02 mm. The insertion point of the LUCL on the ulna was located from the lesser sigmoid notch to the supinator crest and had a width of 9...

OBJECTIVES: Minimally invasive plate osteosynthesis (MIPO) is one of the most recent fixation techniques that embody the concept of biological osteosynthesis. Several studies evaluating MIPO in dogs have been published in the recent years. However, there are few clinical reports of MIPO in cats and no description of the surgical approaches. The purpose of our study was to describe the safe corridors for plate insertion in cats using the MIPO technique. METHODS: The surgical approaches for the humerus, radius-ulna, femur and tibia were developed after reviewing the described techniques and surgical approaches for MIPO in dogs, while considering any relevant anatomical difference between dogs and cats...

INTRODUCTION: Tuberculosis is a major health problem worldwide. Extrapulmonary tuberculosis is often secondary to some primary foci in lungs. There are reports of tuberculous osteomyelitis involving maxilla, ulna, femur, and shoulder joint but none have reported pathological fracture in humeral diaphysis due to tuberculosis osteomyelitis without shoulder joint involvement. We report a case of pathological fracture of humerus diaphysis due to tuberculous osteomyelitis with normal articular space...

Deepak N Bhatia
Proximal humerus fracture fixation may be complicated by persistent postsurgical stiffness or implant-related problems. Arthroscopic plate removal is a cosmetic and functionally beneficial procedure; however, the procedure is technically difficult in the presence of severe subdeltoid scarring. The technique described here shows an arthroscopic subdeltoid adhesiolysis and proximal humerus plate removal using systematic access to 5 regions of screw positions on the plate. After initial glenohumeral adhesiolysis, a thorough subacromial and subdeltoid bursectomy is performed...

Awad Abdelmonem Rafalla, El Sayed Abdelhalim Abdullah
BACKGROUND: Proximal end of the humerus is a common site for both primary and metastatic bone tumors. Limb salvage with endoprosthetic replacement is the most common means of reconstruction, but it has been proved that cement spacer are more beneficial for inferior shoulder function. Thus, limb salvage can be replaced by cheaper spacers especially in poor societies. PATIENTS AND METHODS: This study included 20 patients, of whom 14 were female, with a mean age of 40...

BACKGROUND: The ability to correctly classify fractures is of importance for choosing the appropriate treatment and for providing appropriate data for research and quality registers. In the Swedish Fracture Register (SFR) fractures of all types are registered by the attending physician, often a junior doctor. For the majority of fractures, a modified AO/OTA classification is used. This study aimed to validate the accuracy of classification of humerus fractures in the SFR and also at providing insight into inherent classification uncertainties...

BACKGROUND: Two recent experimental studies evaluated the influence of shoulder rotation on neck-shaft angle, with conflicting results. However, there have been no clinical studies of whether this angle varies in different shoulder positions. The present study aimed to determine whether shoulder rotation affects neck-shaft angle on standard radiographs in patients with complaints of shoulder pain. HYPOTHESIS: Shoulder rotation does not affect neck-shaft angle. MATERIALS AND METHODS: A prospective study was conducted in selected patients with shoulder pain...

Reverse shoulder arthroplasty (RSA) in its modern design was first introduced over 25 years ago and approved by the American FDA over ten years ago. This type of prosthesis allows treatment of glenohumeral joint disease among patients with severe rotator cuff deficiency once thought to be inoperable. Modifications to the prosthesis design, along with improved surgical technique, led to better clinical outcomes and lower complication rates, which subsequently led to an increase in the usage of this implant device...

Septic arthritis of the shoulder can destroy the glenohumeral joint resulting in significant pain, instability and poor function. Surgical treatment is notoriously difficult with significant risk of complications. Shoulder arthrodesis has been performed using both internal and external fixation but has high complication rates in the presence of infection. We present our experience of managing a patient with significant pain and loss of function as a result of septic arthritis of the shoulder following infected proximal humeral fracture fixation with associated proximal humeral osteomyelitis...

We report the treatment process of a pediatric patient with deformity and shortening in the arm after a recurrent aggressive aneurysmal bone cyst (ABC) in the proximal humerus. The patient was treated with curettage of the lesion and lengthening on an intramedullary nail following an osteotomy just distal to the ABC. The period of lengthening was approximately 50 days. At the end of the treatment the lengthening goal was achieved without any neurovascular complication. There was a minimal loss in shoulder hyperabduction due to the deformity of the humeral head...
