BACKGROUND: The aim of this paper is to present the results of hip joint arthroplasty with the use of the Taperloc stem. MATERIAL AND METHODS: The study group consisted of 117 patients (75 women and 42 men) who underwent 121 hip joint arthroplasties with Taperloc stems. Mean age of the patients at surgery was 53.8 years (range: 2475 years). Mean follow-up period was 159.5 months. RESULTS: Pre-operative Merle d'Aubigne-Postel scores (modified by Charnley) of the study group were poor in all patients...

BACKGROUND: Appropriate treatment of radial head fractures remains an area of disputes and controversy. The present paper aims to assess the outcomes of surgical fixation of these injuries and identify the most common complications. MATERIAL AND METHODS: The medical records of 63 patients (25 women and 38 men) treated in 2011 -2014 were analysed retrospectively. The treatment outcomes were assessed according to the Broberg and Morrey rating system and the QuickDASH score...

REVIEW
Kai Yang, Alexander Graf, James Sanger
Heterotopic ossification (HO) is widely recognized as a common occurrence among patients suffering from traumatic spinal cord injuries (SCI). The exact etiology of HO formation remains unknown. Published medical and surgical management strategies are often plagued with questionable effectiveness and frequent complications. There are minimal publications regarding the management strategies of HO in SCI patients as it pertains to plastic surgery. We present a case series of patients treated at our institution who underwent treatment for pressure ulcers with underlying HO to highlight the vast spectrum of clinical phenotypes present in this population...

Heterotopic ossification (HO) is a common complication of the surgical treatment of acetabular fractures. HO is the formation of trabecular bone in soft tissues where bone does not usually occur. Over the last decade, many risk factors have been identified for HO after surgical fixation of acetabular fractures; however, prophylaxis and treatment of this condition are controversial. Potential preventive measures range from NSAIDs to external beam irradiation, but recent studies have questioned the utility of these measures...

PURPOSE: The purpose of this study is to compare INFIX to plating in the treatment of unstable pelvic ring injuries with disruption of the symphysis. METHODS: Twenty-four patients treated with INFIX were compared to 28 patients fixed by plating. All patients had anterior and posterior fixation. Injuries were classified using the Young and Burgess and AO/OTA classification systems. Reductions of the pelvic ring were assessed using the pelvic deformity index (PDI) and symphyseal widening...

Suture button devices such as the TightRope (Arthrex, Naples, Florida) have been increasingly used for syndesmotic fixation of ankle fractures. Despite proposed advantages, prior studies have shown equivalent outcomes, with a theoretical decreased need for removal of hardware. Complications of suture button fixation of syndesmotic instability may be underreported and include lateral suture knot inflammation with or without granuloma formation, infection, aseptic osteolysis with widening of the tibial drill tunnels, heterotopic ossification, and osteomyelitis...

PURPOSE: To demonstrate the feasibility of using CBCT in a real-time image guided radiation therapy (IGRT) for single fraction heterotopic ossification (HO) in patients after hip replacement. In this real-time procedure, all steps, from simulation, imaging, planning to treatment delivery, are performed at the treatment unit in one appointment time slot. This work promotes real-time treatment to create a paradigm shift in the single fraction radiation therapy. METHODS: An integrated real-time IGRT for HO was developed and tested for radiation treatment of heterotopic ossification for patient after hip replacement...

BACKGROUND: Angiogenesis, the formation of blood vessels, is a critical aspect of wound healing. Disorders of wound healing are often characterized by lack of angiogenesis, a condition frequently observed in aging and diabetic patients. Current techniques for assessing blood at injury sites are limited to contrast-imaging, including angiography. However, these techniques do not directly observe oxygenation of blood and are not amenable to serial evaluation. A multimodal noninvasive reflectance and Raman spectrometer have been proposed to help clinicians as a point-of-care tool to interrogate local angiogenesis and tissue architecture, respectively...

PURPOSE: Deformities of the cervical spine are uncommon in the coronal plane. In this report, a unique case of a 31-year-old male with a fixed, 30° left coronal deformity due to heterotopic ossification 3 years status post poly-trauma was treated with an asymmetric C7 pedicle subtraction osteotomy (PSO). METHODS: Case report. RESULTS: Pre-operatively, the patient had a fixed 45-degree left tilt of his neck and radiographs demonstrated a rigid 30° scoliosis, 7 cm coronal imbalance, and 4 cm negative sagittal balance, diffuse bridging bone between the spinous processes and the facet joints of C5 to T1 bilaterally...

PURPOSE: To review the outcome of total hip arthroplasty (THA) using a short femoral stem in 33 hips. METHODS: Records of 33 hips in 20 men and 10 women aged 25 to 40 (mean, 30) years who underwent cementless THA using a short femoral stem by a single senior surgeon were reviewed. The diagnosis included avascular necrosis (n=9), ankylosing spondylitis (n=12), rheumatoid arthritis (n=7), posttraumatic arthritis (n=4), and Hurler syndrome (n=1). Clinical outcome was assessed using the Harris Hip Score...

BACKGROUND: The formation and severity of heterotopic ossification (HO) may be influenced by type of surgical approach. Our hypothesis was that because of differences in soft tissue dissection, differences exist in HO formation in primary total hip arthroplasty using direct anterior (DA) vs direct lateral (DL) approach. METHODS: A total of 1482 consecutive patients with DL (736) or DA (746) approach and similar perioperative care protocol during 2009-2011 were retrospectively studied...

The human TGF-β/SMAD7 signaling has been recognized as an attractive target of heterotopic ossification (HO). Here, we report a successful rational design of cyclic peptides to disrupt the signaling pathway by targeting TGF-β-receptor complex. The intermolecular interaction between TGF-β and its cognate receptor is characterized in detail using molecular dynamics simulation, binding energetic analysis, and alanine scanning. With the computational analysis a binding loop of receptor protein is identified that plays an essential role in the peptide-mediated TGF-β-receptor interaction...

RATIONALE AND OBJECTIVES: Severe progressive multifocal heterotopic ossification (HO) is a rare occurrence seen predominantly in patients who have fibrodysplasia ossificans progressiva (FOP) and is difficult to quantitate owing to patient-, disease-, logistical-, and radiation-related issues. The purpose of this study was to develop and validate a scoring system based on plain radiographs for quantitative assessment of HO lesions in patients with FOP. MATERIALS AND METHODS: Institutional review board approval was obtained from the University of Pennsylvania, and all data comply with Health Insurance Portability and Accountability Act regulations...

Muscle trauma is highly morbid due to intramuscular scarring, or fibrosis, and muscle atrophy. Studies have shown that bone morphogenetic proteins (BMPs) reduce muscle atrophy. However, increased BMP signaling at muscle injury sites causes heterotopic ossification, as seen in patients with fibrodysplasia ossificans progressiva (FOP), or patients with surgically placed BMP implants for bone healing. We use a genetic mouse model of hyperactive BMP signaling to show the development of intramuscular fibrosis surrounding areas of ectopic bone following muscle injury...
