The opposite of a simple fracture is a comminuted fracture, where the bone has been shattered into fragments, or there are secondary fractures along the main fracture lines. High velocity injuries (e.g. those caused by bullets, improvised explosive devices, etc...) will frequently cause comminuted fractures.

Heterotopic ossification of the elbow, after comminuted fracture and arthroplasty. Heteropic ossification of the elbow, after comminuted fracture and arthroplasty. During the early stage, an x-ray will not be helpful because there is no calcium in the matrix. (In an acute episode which is not treated, it will be 3– 4 weeks after onset before the x-ray is positive.) Early laboratory tests are not very helpful.

Patellectomy (in cases of comminuted fracture) is removal of the entire patella, whereas a partial patellectomy is removal of only a portion of the patella, while any ligaments or tendons that had been connected to the removed portion are connected to the remaining portion. The fracture may require tension band wiring (in case of two part fracture) to unite the fractured bones. With advancement of fixation technique comminuted fracture of the patella are being reconstructed (patella saving operations).

Tension band fixation is the most common form of internal fixation used for non-comminuted olecranon fractures. It is typically reserved for noncomminuted fractures that are proximal to the coronoid. This procedure is performed using Kirschner wire (K-wires) which converts tensile forces into compressive force.

Fractures of the sternum are rather uncommon. They may result from trauma, such as when a driver's chest is forced into the steering column of a car in a car accident. A fracture of the sternum is usually a comminuted fracture. The most common site of sternal fractures is at the sternal angle.
|
|
In high velocity injuries, the soft tissue can be severely damaged far from the bullet wound itself due to hydrostatic shock. Because of this the airway must be carefully managed and vessels well examined. Because the jaw can be highly comminuted, MMF and rigid internal fixation can be difficult. Instead, external fixation is often used,.

Direct trauma: This can happen in a fall with landing on the elbow or by being hit by a solid object. Trauma to the elbow often results in comminuted fractures of the olecranon. Indirect trauma: by falling and landing with an outstretched arm. Powerful pull of the triceps muscle can also cause avulsion fractures.

The Rolando fracture is a comminuted intra-articular fracture through the base of the first metacarpal bone (the first bone forming the thumb). It was first described in 1910 by Silvio Rolando.Rolando S. Fracture de la base du premier metacarpien et principalement sur une variete` non encore e`crite. Presse Med 1910;33:303–4 [in French].

Avascular nonunions are subdivided as: # Torsion wedge nonunions have an intermediate fragment with decreased or absent blood supply. This fragment has healed to one main fragment but not to the other. # Comminuted nonunions have one or more intermediate fragments that are necrotic. # Defect nonunions has a gap in diaphysis of bone due to a loss of fragment.

The ore is comminuted using grinding machinery. Depending on the ore, it is sometimes further concentrated by froth flotation or by centrifugal (gravity) concentration. Water is added to produce a slurry or pulp. The basic ore slurry can be combined with a solution of sodium cyanide or potassium cyanide; many operations use calcium cyanide, which is more cost effective.

Non-displaced or minimally displaced fractures may be treated conservatively. Open reduction and internal fixation is reserved for cases that are severely angulated or comminuted. The purpose of fixation is to restore the normal appearance of the face. Specific attention is given to the position of the malar eminence and reduction of orbital volume by realigning the zygoma and sphenoid.

At the time, the plaintiff was suffering from a comminuted spiral fracture of the right tibia and fibula, which gave the appearance of having been caused by a twisting force. Plaintiff's mother had no explanation for this injury. Plaintiff had bruises over her entire body. In addition, she had a non-depressed linear skull fracture which was then in the process of healing.

A gas pycnometer is a laboratory device used for measuring the density—or, more accurately, the volume—of solids, be they regularly shaped, porous or non-porous, monolithic, powdered, granular or in some way comminuted, employing some method of gas displacement and the volume:pressure relationship known as Boyle's Law. A gas pycnometer is also sometimes referred to as a helium pycnometer.

External fixation via TSFs tends to be less invasive than internal fixation and therefore has lower risks of infection associated with it. This is particularly relevant for open fractures. For open comminuted fractures of the tibial plateau the use of circular frames (like TSF) has markedly reduced infection rates. The time taken for bones to heal (time to union) varies depending on a number of factors.

Comminuted midshaft humerus fracture with callus formation. A fibrocartilage callus is a temporary formation of fibroblasts and chondroblasts which forms at the area of a bone fracture as the bone attempts to heal itself. The cells eventually dissipate and become dormant, lying in the resulting extracellular matrix that is the new bone. The callus is the first sign of union visible on x-rays, usually 3 weeks after the fracture.

Meanwhile, SpeXial entered the Chinese market by taking part in web series and web films such as Ultimate Ranger, Men with Sword and Realm of the Immortals, etc. On October 25, Wes injured his right leg with a comminuted fracture while shooting High 5 Basketball. He then announced that he will take a three-month break from his activities to rest on November 7. It is expected that Wes will come back in February 2017.

The comparatively thin bone of the floor of the orbit and roof of the maxillary sinus has no support and therefore it is the inferior wall that collapses mostly. So the medial wall blowout fractures are second most common, whereas superior wall i.e. the roof and lateral wall blowout fractures are uncommon & rare respectively. There are two broad categories of blowout fractures: open door, which are large, displaced and comminuted, and trapdoor, which are linear, hinged, and minimally displaced.

It was a five-hour procedure and was one of the most difficult surgeries Richardson had performed. The surgical team successfully implanted a Synthes stainless steel Locking Compression Plate (LCP) and 27 screws into the colt's injured leg to span the comminuted fracture and joints. They used the LCP because its screws thread into the plate to provide maximum strength. Richardson was one of the first equine surgeons to implement this new technology, originally designed for humans.

There is some evidence that immobilization with the wrist in dorsiflexion as opposed to palmarflexion results in less redisplacement and better functional status. Significant angulation and deformity may require an open reduction and internal fixation or external fixation. The volar forearm splint is best for temporary immobilization of forearm, wrist and hand fractures, including Colles fracture. There are several established instability criteria: dorsal tilt >20°, comminuted fracture, abruption of the ulnar styloid process, intraarticular displacement >1mm, loss of radial height >2mm.

Easter Island and its surrounding islets, including Motu Nui and Motu Iti, form the comminuted apex of a large volcanic mountain rising over from the seabed. It is part of the Sala y Gómez Ridge, a mostly-submarine mountain range with dozens of seamounts. Pukao and Moai are two seamounts west of Easter Island, extending east to the Nazca Seamount. Pukao, Moai and Easter Island were formed during the last 750,000 years, with the last eruption a little over 100,000 years ago.

The Okete Volcanics erupted over short periods, between 1.8 and 3 Ma ago, from at least 27 tuff rings, or scoria mounds, surrounded by lava flows. At Maungatawhiri the initial eruption was of fine-grained volcanic tuffs, thought to be comminuted by water interacting with magma, followed by strombolian activity and lava flows. North of Papanui Point violent phreatomagmatic eruptions have formed tuff rings of airfall and pyroclastic surge deposits. The Okete Volcanics include basanites, alkali olivine basalts, hawaiites, and lavas with ultramafic xenoliths.

The finer regolith, the lunar soil of silicon dioxide glass, has a texture resembling snow and a scent resembling spent gunpowder. The regolith of older surfaces is generally thicker than for younger surfaces: it varies in thickness from in the highlands and in the maria. Beneath the finely comminuted regolith layer is the megaregolith, a layer of highly fractured bedrock many kilometers thick. Comparison of high-resolution images obtained by the Lunar Reconnaissance Orbiter has shown a contemporary crater- production rate significantly higher than previously estimated.

However, he suffered a dead leg midweek during training, and as a result missed both tests, in which England were resoundingly beaten. Once more, he was beset by bad luck and suffered a comminuted fracture of his collarbone in a pre-season match for Gloucester Rugby, which greatly reduced his chances of playing in the autumn tests. He was recalled to the England squad for the 2007 Summer Tour of South Africa, alongside club colleagues Andy Hazell, Nick Wood, Iain Balshaw, Anthony Allen and Alex Brown.

Compare healthy bone with different types of fractures: (a) closed fracture (b) open fracture (c) transverse fracture (d) spiral fracture (e) comminuted fracture (f) impacted fracture (g) greenstick fracture (h) oblique fracture Open ankle fracture with luxation Periprosthetic fracture of left femur In orthopedic medicine, fractures are classified in various ways. Historically they are named after the physician who first described the fracture conditions, however, there are more systematic classifications as well. They may be divided into stable versus unstable depending on the likelihood that they may shift further.

The ore is comminuted and the cobalt rich oxides are separated by froth flotation. The cobalt-bearing concentrate is then mixed with lime and coal, and then melted in a reducing atmosphere. Iron and lighter impurities float to the surface as solid dross or are expelled from the melt as gas. The remaining liquid is composed of a heavier copper smelt containing approximately 5% cobalt that is processed for its copper and a lighter slag that is approximately 40% cobalt that is further refined by hydrometallurgical and electrolytic processing.

These interpretations were based on Viking orbiter imagery, MOC imagery, THEMIS thermal mapping, and MOLA elevation mapping. However, Spirit did not find any lacustrine deposits, instead Spirit found alkaline volcanic rocks, including olivine basalt, comminuted basaltic debris, lavas, and pyroclastic rocks, but no eruption centers. Panoramic photo taken by Spirit Rover on January 1, 2006 from the crater Gusev, looking up a slope and across rippled sand deposits in a dark field dubbed "El Dorado". More recently, satellite images showed the trails of dust devils on Gusev's floor.

After pasteurization, they are immediately transferred to filling vessels and sealed before being cooled down. They are then packed into bottles, cans, or pouches and blast frozen for storage and transport. Manufacturers of canned coconut milk typically combine diluted and comminuted milk with the addition of water as a filler. Depending on the brand and age of the milk itself, a thicker, more paste-like consistency floats to the top of the can (a gravity separation, similar to traditional methods), and is sometimes separated and used in recipes that require coconut cream rather than coconut milk.

The radial head fracture is usually managed by open reduction internal fixation; if the fracture is too comminuted, a radial head implant can be used. Excision of the radial head should be avoided, as the radius will migrate proximally leading to wrist pain and loss of pronation and supination of the wrist. Delayed treatment of the radial head fracture will also lead to proximal migration of the radius. The distal radio-ulnar joint dislocation can be reduced by supination of the forearm, and may be pinned in place for 6 weeks to allow healing of the interosseous membrane.

Philip II of Macedon, the father of Alexander the Great, captured the gold mines of Mount Pangeo in 357 BC to fund his military campaigns. He also captured gold mines in Thrace for minting coinage, eventually producing 26 tons per year. However, it was the Romans who developed large scale mining methods, especially the use of large volumes of water brought to the minehead by numerous aqueducts. The water was used for a variety of purposes, including removing overburden and rock debris, called hydraulic mining, as well as washing comminuted, or crushed, ores and driving simple machinery.

Although only a few multi-ring basins have been definitively dated, they are useful for assigning relative ages. Because impact craters accumulate at a nearly constant rate, counting the number of craters per unit area can be used to estimate the age of the surface. The radiometric ages of impact-melted rocks collected during the Apollo missions cluster between 3.8 and 4.1 billion years old: this has been used to propose a Late Heavy Bombardment of impacts. Blanketed on top of the Moon's crust is a highly comminuted (broken into ever smaller particles) and impact gardened surface layer called regolith, formed by impact processes.

In a game against the Washington Redskins, Joe Theismann's career ended on November 18, 1985, when he suffered a gruesome comminuted compound fracture of his leg while being sacked by New York Giants linebackers Lawrence Taylor and Harry Carson during a Monday Night Football game telecast. The injury was voted the NFL's "Most Shocking Moment in History" by viewers in an ESPN poll, and the tackle was dubbed "The Hit That No One Who Saw It Can Ever Forget" by The Washington Post. At the time, the Redskins had been attempting to run a "flea-flicker" play. The Giants' defense, however, was not fooled, and they tried to blitz Theismann.

The Buildwas Formation comprises olive-green and grey calcareous mudstones and nodular to lenticular calcareous mudstones and argillaceous limestones with shell fragments present throughout. The basal part of the formation consists of grey-green rubbly mudstones, containing comminuted shell debris and overlies the mottled green, grey and purple mudstones of the Rubery Formation with a thick transition in colour and upward decrease in number of hard siltstone beds. The top of the Buildwas Formation shows a gradational increase in thickness of beds and a number of limestone beds, where it grades into the overlying Barr Limestone Formation. The thickness of the formation ranges from , with the thinnest outcrops occurring near Walsall thickening towards Wenlock Edge.

While postmortem glycogen levels are often depleted through the onset of rigor mortis, marine mammals have a much delayed onset of rigor mortis, even in warm conditions, presumably due to the high content of oxymyoglobin in the muscle that may permit aerobic metabolism to continue slowly for some time after the death of the animal. Additionally, in cold conditions, glycogen's depletion is halted at -18 °C (-0.4 °F) and lower temperatures in comminuted meat.Lawrie 2014, p. 298. Traditional Inuit diets derive approximately 50% of their calories from fat, 30–35% from protein and 15–20% of their calories from carbohydrates, largely in the form of glycogen from the raw meat they consumed.

Magnetite is magnetic, and hence easily separated from the gangue minerals and capable of producing a high-grade concentrate with very low levels of impurities. The grain size of the magnetite and its degree of commingling with the silica groundmass determine the grind size to which the rock must be comminuted to enable efficient magnetic separation to provide a high purity magnetite concentrate. This determines the energy inputs required to run a milling operation. Mining of banded iron formations involves coarse crushing and screening, followed by rough crushing and fine grinding to comminute the ore to the point where the crystallized magnetite and quartz are fine enough that the quartz is left behind when the resultant powder is passed under a magnetic separator.

Born in Admont, Styria, Schild initially preferred the downhill event. However, by the age of 19 she had already undergone five knee surgeries, prompting her to concentrate on the less dangerous slalom and giant slalom competitions.T W Flørenes, T Bere, L Nordsletten, S Heir, R Bahr (13 October 2009), "Injuries among male and female World Cup alpine skiers", British Journal of Sports Medicine 2009;43:973–978. Since 2004, she has finished every season (except 2009 when out with injury) among the top 3 in the World Cup slalom standings, and won the slalom trophy in 2007, 2008 and 2011. Her best result in the overall competition was a second place in 2007, when she lost the overall trophy only in the last two races (slalom and giant slalom) against compatriot Nicole Hosp, after having taken the lead with a second place in downhill and a third place in super-G on the first two days of the World Cup final 2007 in Lenzerheide. While training for the giant slalom in October 2008, Schild fell and sustained a comminuted fracture in her left tibia and fibula, as well as a fractured tibial head.

In an 1823 article "On the deluge", John Stevens Henslow, professor of mineralogy at the University of Cambridge, affirmed the concept and proposed that the Flood had originated from a comet, but this was his only comment on the topic. Adam Sedgwick, Woodwardian Professor of Geology at Cambridge, presented two supportive papers in 1825, "On the origin of alluvial and diluvial deposits", and "On diluvial formations". At this time, most of what Sedgwick called "The English school of geologists" distinguished superficial deposits which were "diluvial", showing "great irregular masses of sand, loam, and coarse gravel, containing through its mass rounded blocks sometimes of enormous magnitude" and supposedly caused by "some great irregular inundation", from "alluvial" deposits of "comminuted gravel, silt, loam, and other materials" attributed to lesser events, the "propelling force" of rivers, or "successive partial inundations". In America, Benjamin Silliman at Yale College spread the concept, and in an 1833 essay dismissed the earlier idea that most stratified rocks had been formed in the Flood, while arguing that surface features showed "wreck and ruin" attributable to "mighty floods and rushing torrents of water".
