INTRODUCTION: The deltopectoral and the deltoid splitting approach are commonly used for the treatment of proximal humeral fractures. While the deltopectoral approach requires massive soft tissue devascularization, the deltoid splitting approach needs an additional skipped incision to avoid axillary nerve injury. The purpose of this study was to describe a modified anterolateral deltoid splitting approach with axillary nerve bundle mobilization in the treatment of proximal humeral fractures and to assess its radiologic and clinical outcomes...

Functional limb length discrepancy (LLD) in adolescents can result from soft tissue contracture following long-standing hip disease. We present a case of a 13-year-old girl with difficulty in ambulation due to right hip pain and LLD. Radiographs revealed severe arthritis of right hip with signs of avascular necrosis of the femoral head. The patient had developed reactive scoliosis of lumbar spine along with pelvic obliquity. After failing conservative management, total hip arthroplasty (THA) without attempting to equalize LLD was performed...

PURPOSE: Treatment of slipped capital femoral epiphysis (SCFE), including the modified Dunn procedure, restores anatomy with significant risk for avascular necrosis (AVN), if performed in the setting of moderate to severe, stable SCFE. The Imhauser osteotomy has been shown to be an effective way to correct residual deformity without the risk of AVN. We sought to evaluate the effectiveness and safety of a combined Imhauser osteotomy and osteochondroplasty, performed via a surgical hip dislocation approach for the acute and delayed treatment of stable SCFE...

BACKGROUND: Avascular necrosis of bone (AVN) leads to sclerosis and collapse of bone and joints. The standard of care, vascularized bone grafts, is limited by donor site morbidity and restricted availability. The aim of this study was to generate and test engineered, axially vascularized SVF cells-based bone substitutes in a rat model of AVN. METHODS: SVF cells were isolated from lipoaspirates and cultured onto porous hydroxyapatite scaffolds within a perfusion-based bioreactor system for 5 days...

We present the surgical outcomes of non-vascularized bone grafting taken from the iliac crest in 24 patients with scaphoid nonunion and avascular necrosis. The Fisk-Fernandez technique was used in 11 patients, and cancellous bone grafting was used in 13 patients. Bony union was achieved in 22 of the 24 patients. Non-vascularized iliac bone grafting can be used for the surgical management of scaphoid nonunion with avascular necrosis. Although revascularization of the proximal fragment after surgery was not evaluated, bony union was confirmed in nearly all patients...

BACKGROUND: Post traumatic arthritis and avascular necrosis of the femoral head are common complications after operatively treated acetabular fractures. This may cause severe disabilities for the patient, necessitating a total hip arthroplasty. Even though an arthroplasty may provide good symptomatic relief, the long-term results are more uncertain and no consensus exists according to preferred prosthetic designs. With this cohort study, we aimed to investigate the medium to long term arthroplasty survival and clinical results of total hip arthroplasty after operatively treated acetabular fractures...

Avascular necrosis of the femur head (AVNFH) is a debilitating disease caused due to the use of alcohol, steroids, following trauma or unclear (idiopathic) etiology, affecting mostly the middle aged population. Clinically AVNFH is associated with impaired blood supply to the femoral head resulting in bone necrosis and collapse. Although Homocysteine (HC) has been implicated in AVNFH, levels of homocysteine and its associated pathway metabolites have not been characterized. We demonstrate elevated levels of homocysteine and concomitantly reduced levels of vitamins B6 and B12, in plasma of AVNFH patients...

Mesenchymal stem cells (MSCs)-derived exosomes exhibit protective effects on damaged or diseased tissues. Hypoxia-inducible factor 1α (HIF-1α) plays a critical role in bone development. However, HIF-1α is easily biodegradable under normoxic conditions. The bone-marrow-derived mesenchymal stem cells (BMSCs) were transfected with adenovirus carrying triple point-mutations (amino acids 402, 564, and 803) in the HIF-1α coding sequence (CDS). The mutant HIF-1α can efficiently express functional proteins under normoxic conditions...

AIM: There is no evidence on the effect of universal ultrasound screening on developmental dysplasia of the hip. We examined the impact of adding an ultrasound examination to a one examiner clinical screening strategy on treatment, follow-up rates and the number of cases detected late in a low-prevalence population. METHODS: All eligible babies born at Kongsberg Hospital, Norway, from 1998-2006 (n=4,245) underwent both clinical and ultrasound hip examinations within three days of life...

Total ankle arthroplasty is a viable surgical technique for the treatment of end-stage degenerative joint disease. With continued advancement in prosthetic design, refined surgical techniques, and improved outcomes, the indications for total ankle replacement have expanded to include cases of increasing complexity. With meticulous preoperative planning and exacting execution, many frontal plane deformities and cases of avascular necrosis can now be successfully addressed at the time of prosthesis implantation or in a staged procedure...

Trans-scaphoid transcapitate (TSTC) perilunate fracture-dislocation (PLFD) is a rare type of perilunate injury. Because of the rarity and complexity of this entity, initial diagnosis may be delayed and the extent of osseous and ligamentous lesions underestimated. Early surgical treatment by open reduction and fracture stabilization is recommended to avoid complications such as avascular necrosis, nonunion, posttraumatic arthritis, and functional impairment. In this article, we report the case of a 32-year-old man who sustained a TSTC-PLFD...

BACKGROUND: Proximal humerus fractures account for approximately 4-6% of all fractures. While the majority of these fractures are treated non-operatively, the amount of fracture displacement, concomitant injuries, and patient factors often result in the need for surgical stabilization. Although concomitant neurovascular injury in the setting of low-energy trauma is rare, injury to the surrounding neurovascular structures have previously been reported. METHODS: We report a case of a 79-year-old male who sustained a low energy fall resulting in a two-part fracture dislocation of the proximal humerus with an associated brachial plexopathy and axillary artery laceration...
