The broken bone tilts upward and away from the center of the body, making it a type of distal fracture with dorsal angulation. (handandwristinstitute.com)
The scaphoid receives its primary blood supply from the dorsal scaphoid branches of the radial artery, which enter the scaphoid at a point near the distal pole. (orthopaedia.com)
On the dorsal surface of the carpus, a gentle convex arch is formed by the arrangement of the proximal and distal rows. (teachmeorthopedics.info)
Patients with Colles fractures usually have a characteristic dorsal deformity of the distal segment of the radius, whereas patients with scaphoid fractures do not. (radiologykey.com)
Most of the blood supply comes from the dorsal carpal branch of the radial artery. (wikidot.com)
On the dorsal surface is a narrow, rough groove, which runs the entire length of the bone, and serves for the attachment of ligaments. (en-academic.com)

Here at The Hand and Wrist Institute, we're going to discuss two common types of wrist fractures your doctor may diagnose: Colles and scaphoid. (handandwristinstitute.com)
Read on to discover the importance of distinguishing between Colles and scaphoid fractures and the treatment options for each. (handandwristinstitute.com)
What Is a Colles Fracture? (handandwristinstitute.com)
A Colles fracture is a type of broken wrist in which an impact to your hand transfers energy to your radius (arm bone). (handandwristinstitute.com)
Colles and scaphoid fractures may occur if your wrist experiences any type of trauma. (handandwristinstitute.com)
Anyone can sustain either type of fracture, but Colles fractures are most common in women aged 60 and older with osteoporosis. (handandwristinstitute.com)
The symptoms of Colles and scaphoid fractures are similar. (handandwristinstitute.com)
The pain from a scaphoid fracture usually occurs closer to the thumb, while the pain from a Colles fracture might be more persistent near your wrist. (handandwristinstitute.com)
An X-ray can reveal if you have a Colles or scaphoid fracture and provide insight into the severity of the injury. (handandwristinstitute.com)
Colles and scaphoid fractures require medical treatment, as serious complications might arise if you try to let them heal on their own. (handandwristinstitute.com)
The Colles fracture is a particularly common type of fracture of the distal radius bone, caused by a fall onto an outstretched hand. (drnagarkar.com)
Like Colles fractures, scaphoid (navicular) fractures are usually caused by a fall onto an outstretched hand with the wrist in hyperextension, but they can result in other ways. (radiologykey.com)
Note that patients with both Colles fractures and scaphoid fractures may present with pain with limited range of motion. (radiologykey.com)
In addition, another key clinical clue helps differentiate a scaphoid fracture from a Colles fracture. (radiologykey.com)

[ 29 ] An increasing wrist ratio correlates with prolongation of the median nerve sensory latencies and distal motor latencies. (medscape.com)
It should be noted that these fractures may be complicated by a median nerve injury. (aafp.org)
Any process that increases pressure within the carpal tunnel can compress the median nerve leading to sensory and motor dysfunction. (ajops.com)
The carpal tunnel is a narrow passage in the wrist that the median nerve and the flexor tendons run through. (juzo.ch)
The typical pressure in the carpal tunnel, surrounding the median nerve, is between 2 to 10 mm Hg. (intecorept.com)

However, with dorsiflexion (95-100°) and radial deviation (10°), the scaphoid becomes trapped between the volar edge of the radius proximally and the trapezium and trapezoid distally at the level of the radioscaphocapitate ligament, thereby fracturing the scaphoid through impaction. (medscape.com)
A tuberosity on the distal palmar aspect serves as an attachment site for the transverse carpal ligament. (orthopaedia.com)
A broken bone or a torn ligament takes around 6 weeks to heal. (drnagarkar.com)
Often the etiology is post-traumatic, either from fracture or prior ligament injury. (edmondsorthopediccenter.com)
Once the transverse carpal tunnel ligament was released, florid synovitis, turbid fluid and hyperaemia were seen during exploration. (ajops.com)
The volar surface is concave above, and elevated at its lower and lateral part into a rounded projection, the tubercle, which is directed forward and gives attachment to the transverse carpal ligament and sometimes origin to a few fibers of the Abductor pollicis brevis. (en-academic.com)
If dealing with a rotated avulsion fracture without associated ligament injury, this can be approached through a palmar incision on the radial side . (aofoundation.org)

Reverse deformity is seen in volar angulation (Smith's fracture). (wikipedia.org)
Tenderness at an area with no obvious deformity may still point to underlying fractures. (wikipedia.org)
Because scaphoid fractures may occur without bruising or visible deformity, patients may assume a less serious injury and delay seeking evaluation. (orthopaedia.com)

Of scaphoid fractures, 15-20% occur at the proximal pole, while 10-15% occur through the distal pole of the scaphoid. (medscape.com)
The proximal pole is opposite of the distal pole, as it's the end closest to your forearm and points toward your body. (handandwristinstitute.com)
The scaphoid can be morphologically divided into three anatomic regions: proximal third (proximal pole), central third (waist), and distal third (distal pole). (orthopaedia.com)
Nearly 2/3 of all scaphoid fractures occur at the waist, with 15% occurring at the proximal pole, 10% at the distal pole, and 8% at the tuberosity. (orthopaedia.com)
Because of this retrograde blood supply, an injury to the scaphoid waist (i.e. the middle third of the bone) can interrupt blood supply to the proximal pole. (orthopaedia.com)
This is analogous to femoral neck fractures and resulting femoral head ischemia: just as the vessels to the femoral head must traverse the femoral neck, the blood supply to the proximal pole of the scaphoid must traverse the waist). (orthopaedia.com)
3 It consists of four main parts, the proximal pole, the waist, and the distal pole which contains the tubercle. (wikidot.com)
This branch enters the bone at the distal tubercle and accounts for only 20-30% of the total supply, which does not reach the proximal pole. (wikidot.com)

The distal row includes (from radial to ulnar) the trapezium, trapezoid, capitate, and hamate. (teachmeorthopedics.info)
The carpal groove is accentuated by the palmar projection of the pisiform and hook of the hamate ulnarly, and by the projection of the scaphoid tuberosity and trapezial ridge radially. (teachmeorthopedics.info)
The pisiform bone, located on the ulnar and palmar aspect of the base of the hand, provides a visible and palpable landmark that aids in the identification and location of the flexor carpi ulnaris (FCU) tendon, the underlying ulnar neurovascular bundle, and the hook process of the hamate. (teachmeorthopedics.info)
The hook of the hamate, located on the ulnar and palmar aspect of the distal carpus, can be palpated approximately 1 cm radial and distal to the pisiform. (teachmeorthopedics.info)
The hook of the hamate lies between the ulnar tunnel (Guyon's canal) and the carpal tunnel. (teachmeorthopedics.info)

Intra-articular vs extra-articular - These terms indicate whether the fracture extends into the radiocarpal joint (the joint between the radius and the first row of carpal bones in the wrist) or not. (atlphysio.com)
1 , 2 , 3 , 4 The three-compartment (i.e., triple injection) arthrogram, in which contrast is introduced into the radiocarpal, distal radioulnar, and midcarpal joints, was considered the standard technique. (musculoskeletalkey.com)
5 , 6 Subsequently, single-compartment arthrograms of the radiocarpal joint have been shown to have a false-negative rate of only 2% for complete perforations and 10% for complete and partial perforations together, and no additional information was provided by selective second and third injections of the distal radioulnar and midcarpal joints. (musculoskeletalkey.com)

The most common mechanism of injury for radius and ulna fractures is sudden axial loading onto the radius/ulna, often from a fall onto an outstretched hand with wrist extension. (aafp.org)
Metacarpal neck fractures usually result from an axial load (eg, from punching with a clenched fist). (msdmanuals.com)
The combination of snuffbox tenderness, scaphoid tubercle tenderness, and pain with axial compression is 100% sensitive for a scaphoid fracture. (radiologykey.com)

Nocturnal pain and paresthesias may awaken the patient from sleep when prolonged wrist flexion or extension leads to increased pressure in the carpal tunnel. (medscape.com)

At that point, the absence of fracture line or healing response on x-ray, coupled with an absence of tenderness on exam reasonably excludes the diagnosis of fracture. (orthopaedia.com)
When plain radiographs do not show a fracture and there is persistent wrist pain, an MRI-arthrogram of the wrist can be helpful in establishing the diagnosis. (edmondsorthopediccenter.com)

All carpal bones participate in wrist function except for the pisiform, which is a sesamoid bone through which the flexor carpi ulnaris tendon passes. (medscape.com)
The pisiform is located palmar to the plane of the remaining three carpal bones of the proximal row, and the pisotriquetral joint is separated from the adjacent articulations. (teachmeorthopedics.info)

The purpose of this study was to determine if DRUJ congruency and mechanics were altered in patients with malunited distal radius fractures. (netlify.app)
When the arm is in the resting position beside the body, the range of motion for pronation is 61-66°, while for supination it is 70-77° Distal Radioulnar Joint Se hela listan på journals.lww.com Distal radioulnar joint (DRUJ) disorders are uncommon but important causes of ulnar‐sided wrist pain and disability. (netlify.app)
DRUJ + PRUJ = Longitudinal rotations= Special type Bicondylar joint Structural & Functional separation btw DRUJand carpal bones = pronation-supinationwithout affecting grasping 3. (netlify.app)
We have a lot to learn about the distal radio-ulnar joint (DRUJ) which is part of the forearm rotation movement. (readinghandsurgery.com)
It may not be possible to assess DRUJ stability until the fracture has been stabilized (as described below). (aofoundation.org)

Attritional ruptures caused by chronic, degenerative carpal pathology are less common. (thieme-connect.de)
1 , 2 , 3 , 4 , 5 , 6 Routine radiographs or computed radiography (CR) and fluoroscopically positioned spot films are usually adequate for identification of fractures and other osseous pathology. (musculoskeletalkey.com)

Radial head fractures may be difficult to visualize on initial imaging but should be suspected when there are limitations of elbow extension and supination following trauma. (aafp.org)

Damage to adjacent structures such as nerves, muscles or blood vessels, spinal cord, and nerve roots (for spine fractures), or cranial contents (for skull fractures) may cause other specific signs and symptoms. (wikipedia.org)

Over the last few decades, significant advances have occurred in the understanding of wrist anatomy, pathophysiology, and carpal kinematics. (medscape.com)
In this system, the author combines fracture anatomy, stability, and chronicity of scaphoid fractures in an alphanumeric system (below). (medscape.com)
4 Alternately, Gray's Anatomy states that in approximately 10% of the population the blood supply comes exclusively from the radial artery and enters through the distal pole. (wikidot.com)
Imaging of the hand and wrist can be difficult due to the complex bone and soft tissue anatomy. (musculoskeletalkey.com)
[ 1 ] This refers to the shape of the bone, supposedly reminiscent of a boat, and in older literature on human anatomy [ 2 ] the scaphoid is referred to as the navicular bone of the hand, since there is also a bone in a similar position in the foot, called the navicular. (en-academic.com)

MRIs and CT scans are also useful for detecting occult scaphoid fractures that don't show up well or at all on X-rays. (handandwristinstitute.com)
This test can detect an occult scaphoid fracture immediately, as well as any other associated injury. (orthopaedia.com)
Figure 5: MRI showing a radiographically occult scaphoid fracture. (orthopaedia.com)
Although bone scans (scintigraphy) can also be used to detect occult scaphoid fractures, MRI has two advantages (Figure 5). (orthopaedia.com)
Carpal bone fractures, trabecular injury, and occult fractures can be seen on MRI. (edmondsorthopediccenter.com)
It is primarily used to evaluate occult or complex fractures, fracture healing, and lucent defects and to provide improved definition of osseous detail. (musculoskeletalkey.com)

Isolated midshaft ulna (nightstick) fractures are often caused by a direct blow to the forearm. (aafp.org)
The 5th metacarpal neck bone is fractured midshaft. (msdmanuals.com)

Skull fractures are common in the setting of both closed traumatic brain injury and penetrating brain injury . (radiopaedia.org)
This article will focus on the general terminology of fractures and delegate discussion of particular fracture patterns to separate articles (e.g. base of skull fractures ). (radiopaedia.org)
Skull fractures are best imaged with CT of the brain. (radiopaedia.org)
Skull fractures, if closed and undisplaced, rarely need any direct management, with treatment being aimed at any associated injury (e.g. extradural hematoma). (radiopaedia.org)

Bone disorders - Patients who suffer from a bone disorder, such as Osteoporosis, are more likely to break their wrist in even a minor fall. (atlphysio.com)
Other possible causes include bone and joint damage, muscular problems, irritation, nerve damage and circulatory disorders . (juzo.ch)

The scaphoid links the carpal bones closest to the radius and ulna, the so-called the "proximal row," to those articulating with the metacarpals, the "distal row. (orthopaedia.com)
Fractures of the neck of metacarpals 2 through 5 are common. (msdmanuals.com)
These are grouped into carpals, metacarpals, and phalanges. (medscape.com)
The distal row of carpal bones is strongly attached to the base of the second and third metacarpals, forming a fixed unit. (medscape.com)
