Age estimation is a crucial parameter involved in investigations pertaining to civil and criminal procedures. It also aids in various examinations in forensic medicine, pediatrics, endocrinology and radiology. One of the important methods for skeletal age estimation is the age of fusion of the epiphyses. But there occur variations in the skeletal ages due to environmental, hormonal, ethnic and other factors. Hence, there arises the need for separate standards of ossification for different regions. The present study was conducted to ascertain the age of fusion of the distal radial and ulnar epiphyses in Kashmiri population...

AIMS: We report the use of the distal radius and ulna (DRU) classification for the prediction of peak growth (PG) and growth cessation (GC) in 777 patients with idiopathic scoliosis. We compare this classification with other commonly used parameters of maturity. PATIENTS AND METHODS: The following data were extracted from the patients' records and radiographs: chronological age, body height (BH), arm span (AS), date of menarche, Risser sign, DRU grade and status of the phalangeal and metacarpal physes...

BACKGROUND: In the recent years, considerable improvements have come in biomechanical knowledge about the role of elbow stabilizers. In particular, the complex interactions among the different stabilizers when injured at the same time have been better understood. Anyway, uncertainties about both nomenclature and classification still exist in the definition of the different patterns of instability. MATERIAL AND METHODS: The authors examine the literature of the last 130 years about elbow instability classification, analyzing the intuitions and the value of each of them...

The aim of the present study was to assess the curative effects of three surgical approaches for a giant cell tumor (GCT) of the distal radius and ulna. A total of 27 patients with GCT on distal radius and ulnas (7 and 20, respectively), confirmed by biopsy, were treated with individualized treatment regimens, according to the Campanacci's grade system: i) Curettage plus inactivated tumor bed and allogeneic bone graft/bone cement augmentation for Campanacci's grade I GCT of the distal radius and ulna (Group A); ii) simple en bloc resection for Campanacci's grade II and III GCT of the distal ulna (Group B); iii) en bloc resection and reconstruction with non-vascularized fibular autograft/allogeneic bone graft for Campanacci's II and III GCT of the distal radius (Group C)...

Fractures of the neck and/or head of the ulna or distal ulna fracture (DUF) other than ulnar styloid fractures can occur in combination with distal radius fractures (DRF). This combination can have a significant influence on the treatment and prognosis since it causes the entire distal forearm to be unstable. In a series of 1279 consecutive unilateral DRFs, we found an associated ulnar neck fracture in 5.9% of cases, ulnar head and neck fracture in 1.6%, and isolated ulnar head fracture in 1.4%. Overall, 9% of cases in this study had a DUF with a DRF...

Distal radius fractures (DRF) are often complex injuries that can impact the radial metaphysis (M), the radial epiphysis (E) and the distal ulna (U). Each of these parameters can influence the outcome. In a given injury, these three DRF components are involved to a varying degree and are variably associated. The MEU classification independently analyzes the three main bone components of the fracture; thus, all possible combinations and each specific injury can be described. It accurately depicts the type and severity of the DRF...

None of the classification systems for distal radius fractures is ideal. However a validated system to analyze these fractures is available that is based on the "metaphysis, epiphysis, ulna" (MEU) classification and the "patient, accident, fracture" (PAF) system. It makes it possible to understand the injury and select the best treatment.

Radiological analysis of acute distal radius fractures (DRF) begins with the initial AP and lateral X-ray views. A CT scan is very often indicated. In addition to the three standard planes, 3D reconstructions are mandatory. We recommend not only AP views of the distal facets of the radius but also a complete 3D view in the surgical position. The distal ulna and carpus should also be analyzed. We describe the radiological sequence and the criteria used. These criteria are recorded in the one-page PAF chart, since they all impact the treatment choice...

In a Sidonian sarcophagus, from the Late Antique/early Christian period, skeletal remains of two persons were found. One of them, male, 30-50 years old, was found almost completely ankylosed, with highly osteoporotic bones and prominent erosion of joint surfaces. We diagnosed rheumatoid arthritis based on the eroded odontoid process, mandibular condyles, distal humerus, proximal and distal ulna, as well ankylosed hand and foot bones. Despite the fact that ankyloses of vertebrae and sacroiliac joint could point towards ankylosing spondylitis, the lack of typical vertebral ankyloses and new bone formation led to exclusion...

The olecranon process, coronoid process, and greater sigmoid notch are important components of the complex proximal ulna. Along with providing bony stability to the ulnohumeral joint, the proximal ulna serves as the attachment site of many important muscles and ligaments that impart soft tissue stability to the elbow joint. Management of proximal ulnar fractures continues to evolve as advances in imaging and anatomic and biomechanical studies have led to improvements in available implants; however, controversies remain, as shown in the current relevant literature...

PURPOSE: Full or selective wrist denervation is an effective treatment for chronic wrist pain. In this cadaveric study, a volar approach for prophylactic denervation of the posterior interosseous nerve (PIN) and the anterior interosseous nerve (AIN) was assessed, which can simultaneously be performed during volar approaches for distal radius fracture fixation or in combination with metalwork removal. MATERIALS AND METHODS: In total 40 adult upper limbs, embalmed using Thiel's method, were investigated...

Background and purpose - The AO Pediatric Comprehensive Classification of Long Bone Fractures (PCCF) describes the localization and morphology of fractures, and considers severity in 2 categories: (1) simple, and (2) multifragmentary. We evaluated simple and multifragmentary fractures in a large consecutive cohort of children diagnosed with long bone fractures in Switzerland. Patients and methods - Children and adolescents treated for fractures between 2009 and 2011 at 2 tertiary pediatric surgery hospitals were retrospectively included...

BACKGROUND: Fractures of the coronoid process or the supinator crest, as well as arthroscopic resection of osteophytes around the coronoid process, can endanger the attachment of the annular ligament (AL) to the proximal ulna. The purpose of this study was to investigate the corresponding insertional areas of the AL within this context. METHODS: In 30 embalmed human cadaveric elbow specimens, the insertional area of the AL at the anterior and posterior margin of the sigmoid notch was characterized...

OBJECTIVES: Several studies focusing diagnosis of forearm fracture using Point-of-Care-Ultrasonography (POCUS) had been carried out in children. There is a lack of evidence for the utility of sonographic (US) examination for detecting of distal forearm fracture in adults. We aim to determine the diagnostic sensitivity and specificity of POCUS examination for the fracture of the distal radius and ulna in adult patients presenting with blunt forearm trauma. MATERIAL AND METHODS: Adult patients presenting with acute distal forearm trauma and suspicion of fracture were enrolled into study...

: We present the results of short- to medium-term follow-up of 10 patients following ulna head replacement. The mean age of patients was 63.2 years (range 48-81 years), with the mean duration of follow-up being 48 months (12-88 months). The indications for the procedure were primary osteoarthritis (n = 3), post-traumatic osteoarthritis (n = 4), failed Darrach's procedure (n = 2) and rheumatoid arthritis (n = 1). Two patients required revision (20%), one for gross aseptic loosening of the stem and another for an initially oversized head...

Identification and interpretation of pathologies in the fossil record allows for unique insights into the life histories of extinct organisms. However, the rarity of such finds limits not only the sample size for palaeopathologic studies, but also the types of analyses that may be performed. In this study, we present the first occurrence of a palaeopathology in a vertebrate from the Mesozoic of the East Coast of North America (Appalachia), a pathologic ulna and radius of an indeterminate hadrosaur from the Navesink Formation (New Jersey)...

By following the common definition of forward-dynamics simulations, i.e. predicting movement based on (neural) muscle activity, this work describes, for the first time, a forward-dynamics simulation framework of a musculoskeletal system, in which all components are represented as continuous, three-dimensional, volumetric objects. Within this framework, the mechanical behaviour of the entire muscle-tendon complex is modelled as a nonlinear hyperelastic material undergoing finite deformations. The feasibility and the full potential of the proposed forward-dynamics simulation framework is demonstrated on a two-muscle, three-dimensional, continuum-mechanical model of the upper limb...

Franck Launay, Sébastien Pesenti
The risk and consequences of an elbow or a wrist contracture are lower during a forearm lengthening than during a lower limb lengthening. This kind of complication can mostly be avoided by an active and intensive regimen of physiotherapy. However, there are some challenges to deal with in treating the disorder multiple exostoses and the radial club hand, including the lack of consensus on the best treatment for multiple exostoses. However, it is important to realize that the evolution of multiple exostoses can lead to a radial head dislocation which will damage the pronation and the supination range of motion...

Multiple non-ossifying fibromas (MNOFs) occur either isolated or in association with other anomalies, are usually localized in the long bones of the lower limbs, may be radiographically confused with other skeletal lesions, and tend to heal spontaneously with the completion of the skeletal growth. Segmental distribution, either monomelic or polymelic and ipsilateral, is rare and commonly observed in the context of developmental diseases known as "RASopathies", which are caused by mutations in genes that encode components or regulators within the Ras/mitogen-activated protein kinase signaling pathway...
