Rupture of the inner lilgament in the metacarpophalangeal joint of the thumb (skier’s thumb)

RUPTURE OF THE INNER LIGAMENT IN THE METACARPOPHALANGEAL JOINT OF THE THUMB

Diagnosis: RUPTURE OF THE INNER LIGAMENT IN THE METACARPOPHALANGEAL JOINT OF THE THUMB
(Ruptura traumatica ligamentum collaterale ulnare, Skier’s thumb)


Anatomy:
The five fingers on a hand consists of 14 small tubular finger bones (phalanges). The finger bones are held together by various ligaments. The joint capsule around the metacarpophalangeal joint (MCP, knuckle joint) is strengthened by three ligaments (two side ligaments and one ligament under the joint (volar)). The ligament on the thumb’s inner side (lig collaterale ulnare) is particularly powerful (Photo)

Cause: A blow, twisting or overstretching can result in a ligament rupture occurring. In some cases a piece of bone can become detached where the ligaments fasten on the side of the bone. The rupture often occurs when skiers fall and their thumb is forced back and outwards (e.g. if it is caught in the ski stick). The injury is also called “Skier’s thumb”.

Symptoms: With a ruptured ligament there will often be a swelling of the joint and tenderness on the inner side. The joint feels loose and it is difficult to turn a key in the door or hold a piece of paper between the thumb and index finger.

Acute treatment: Click here.

Examination: It is advisable for everyone with sudden powerful pains in the thumb to have the joint examined to ensure the correct diagnosis and treatment. The results are best if the diagnosis is made and treatment is commenced immediately after the injury (article).
In X-rays you can occasionally see the tears in the ligament fastenings on the side of the finger.

Treatment: Most ligament ruptures internally in the thumb, with clear looseness, require surgery. It may be necessary with an X-ray examination, ultrasound (article) or an MR scan (article).

Rehabilitation: Fitness training in the form of cycling and running, along with rehabilitation according to the guidelines under rehabilitation, general, can usually be commenced immediately. Once the pain is completely gone you can participate in sports activity, although handball, volleyball, basketball and similar activities should be avoided for a few additional weeks.

Bandage: You will often be able to stabilize the joint with tape (tape-instruction) .

Complications: In the vast majority of cases the ligaments heal without complications. In case of lasting pain and lack of progress you should consult your doctor again.

Drop finger

DROP FINGER

Diagnosis: DROP FINGER
(Ruptura traumatica tendinis musculi extensoris digitorum)


Anatomy:
The five fingers on a hand consist of a total of 14 small, tubular finger bones (phalanges). Above the fingers (dorsal) runs the stretching tendons and below (volar) runs the flexor tendons.

  1. M. extensor indicis
  2. M. extensor digitorum

EXTENSOR TENDON OF THE HAND

Cause: With a blow to the finger tip (soccer goalkeepers, handball and volleyball players) a rupture of the stretching tendon can occur at the fastening on the finger’s outer joint. A severing of the piece of bone where the tendon fastens often occurs at the same time.

Symptoms: Pain on top of the finger’s outer joint, which cannot be stretched completely.

Acute treatment: Click here.

Examination: Everyone with sudden powerful pains in a finger and stretching defect should be medically examined. The diagnosis is usually straight forward, but in cases with a stretching defect an x-ray examination should be performed to evaluate whether surgery is indicated.

Treatment: Bandaging of the finger with the outer part completely stretched. Usually a small fingerstall of plastic (Oakley-splint) is used. The plastic bandage must be used for at least 6 weeks. Surgery may be indicated if a larger bone severing has occurred.

Rehabilitation: Fitness training in the form of cycling and running, along with rehabilitation according to the guidelines under rehabilitation, general, can usually be commenced immediately. Once the pain is completely gone you can participate in sports activity, although handball, volleyball, basketball and similar activities should be avoided for a few additional weeks after removal of the splint.

Bandage: It will often relieve the injury if, after the bandage has been removed, the injured finger is taped to its neighbour (tape-instruction)

Complications: In the vast majority of cases the tendon rupture heals without complications. In a number of cases a small stretching defect will remain, which increases the chance of renewed injuries from handball, volleyball etc., which is why tape treatment can be indicated.

Degenerative arthritis in the hand

DEGENERATIVE ARTHRITIS IN THE HAND

Diagnosis: DEGENERATIVE ARTHRITIS IN THE HAND
(Osteoarthritis)


Anatomy:
The bones in the wrist consist of 8 carpal bones (ossa carpi), that along with the two forearm bones, ulna and the radius, form the wrist. Furthermore there are 5 metacarpus bones (ossa metacarpi) and a total of 14 finger bones (phalanges).

Cause: In case of repeated loads the cartilage, primarily, and subsequently the bone beneath the cartilage, can be damaged (degenerative arthritis). The degenerative changes can in some cases cause an inflammation of the synovial membrane (synovitis), which implies fluid formation, swelling, movement constriction and pain in the joint. Degenerative changes in the hand often occur after earlier injuries (bone fractures, sprains). Degenerative changes are most frequently seen in the wrist itself (articulatio radiocarpale) or corresponding to the thumbs root joint (articulatio carpometacarpale pollicis) and in the outer joint of the finger (DIP-joint)

Symptoms: Pain in the joint upon movement. Occasional swelling in the joint (synovitis).

Examination: Often an ordinary clinical examination is sufficient, although it may be necessary to supplement with an x-ray examination. Ultrasound is well suited to detect fluid in the joints (Ultrasonic image) (article).

Treatment: Relief from pain inducing activities until the swelling has decreased. Rehabilitation can subsequently be commenced with the primary goal to strengthen the muscles around the joint and maintain joint-mobility. There is no treatment that can regenerate the destroyed cartilage (and bone). Cartilage transplants are not yet suitable for general degenerative changes. In cases of swelling in the joint, you can attempt to dampen the inflammation (synovitis) with rheumatic medicine (NSAID) or by draining the joint fluid and injecting corticosteroid, which can advantageously be done with ultrasound guidance. Pain with no swelling is best treated with paracetamol.

Rehabilitation: The rehabilitation is dependant on which joint has suffered degenerative changes. Exercise is generally advised to maintain joint mobility and non-strenuous strength training for the muscles around the joint, which, however, does not have as large an effect as around joints with large muscles (e.g. the knee).
Also read rehabilitation, general.

Bandage: With degenerative changes in the wrist and thumb a bandage that supports (and relieves) the joint, can be manufactured. With degenerative changes in the thumbs base joint (MCP joint), a tape can be applied (tape-instruction) .

Complications: With severe degenerative changes with pain when resting (at night) it may become necessary to fix the joint by an operation. It should be considered whether the swelling in the joint is not part of a general rheumatic disorder.

Inflammation of the tendon sheath

INFLAMMATION OF THE TENDON SHEATH

Diagnosis: INFLAMMATION OF THE TENDON SHEATH
(Tenosynovitis)


Anatomy:
The five fingers on a hand consist of a total of 14 small, tubular finger bones (phalanges). Above the fingers (dorsal) runs the stretching tendons and below (volar) runs the flexor tendons. In most places the tendons are surrounded by a tendon sheath.

TENDON SHEATHS ON THE PALM OF THE HAND

Cause: Tenosynovitis occurs due to mechanical irritation of the tendon sheath following repeated uniform movements of the tendon, causing the tendon to become inflamed, swollen and sometimes crepitate upon movement (article 1). In some cases long-term inflammation of the tendon sheath can cause a weakening and in the worst cases a rupture of the tendon (article 2).

Symptoms: Pain along the tendon sheath, which can sometimes feel swollen and crepitating upon movement.

Acute treatment: Click here.

Examination: Slight cases do not necessarily require medical examination. The doctor should be consulted if there is lack of progress despite relief. The diagnosis is usually made from a normal medical examination, however, in the event of doubt in connection with the diagnosis an ultrasound scan can be performed which will easily and quickly detect the inflammation (article), (Ultrasonic image).

Treatment: Relief from the triggering load factor. In case of lack of progress with relief, a medical treatment in the form of rheumatic medicine (NSAID) or the injection of corticosteroidi in the tendon sheath can be considered. Since the effect and the risk is dependant on the injection being done correctly, it can advantageously be performed with ultrasound guidance.

Rehabilitation: Usually fitness training in the form of cycling, running and rehabilitation according to the guidelines under rehabilitation, general can be started immediately.

Bandage: With many tenosynovitis cases a support splint can be used to advantage as needs require.

Complications: Lengthy periods of tenosynovitis can cause damage to the tendon resulting in a rupture of the tendon, following which the functions of the fingers (stretching, bending) can suddenly be lost.

Inflammation of the tendon sheath on the outer wrist

INFLAMMATION OF THE TENDON SHEATH ON THE OUTER WRIST

Diagnosis: INFLAMMATION OF THE TENDON SHEATH ON
THE OUTER WRIST

(Tenosynovitis styloideae radii, De Quervain)


Anatomy:
The tendons around the wrist are surrounded by tendon sheaths, as are the tendons located externally (radial) on the wrist which contribute to the movement of the thumb (M abductor pollicis longus and M extensor pollicis brevis).

TENDON SHEATHS ON THE BACK OF THE HAND

Cause: Inflammation of the tendon sheath (tenosynovitis) occurs as a result of mechanical irritation of the tendon sheath due to repeated uniform movements of the tendon, causing the tendon to become inflamed and swell (article).

Symptoms: Slowly commencing pain along the wrist on the side of the thumb. The area can occasionally feel swollen, and crackling sensation felt upon movement of the thumb. The pain deteriorates when twisting a rag, and when the thumb is moved away from the index finger against resistance.

Acute treatment: Click here.

Examination: Slight cases do not necessarily require medical examination. The doctor should be consulted if there is lack of progress despite relief. The diagnosis is usually made from a normal medical examination, however, in the event of doubt in connection with the diagnosis an ultrasound scan can be performed which will easily and quickly detect the inflammation (Ultrasonic image) (article).

Treatment: The treatment primarily involves relief, stretching and strength training of the muscles around the wrist. It is imperative for the treatment that the triggering load factor is reduced (article). In cases with a lack of progress following relief, a medical treatment can be considered in the form of rheumatic medicine (NSAID) or the injection of corticosteroid in the tendon sheath. Since the effect and the risk is dependant on the injection being performed correctly, the injection can advantageously be executed under ultrasound guidance. Surgery is rarely indicated.

Bandage: It will often relieve the injury if a wrist splint is used.

Complications: If there is a lack of progress it should be considered if the diagnosis is correct or whether complications have arisen:

Sprained finger joint

SPRAINED FINGER JOINT

Diagnosis: SPRAINED FINGER JOINT
(distorsio articuli digiti)


Anatomy:
The five fingers on a hand consist of a total of 14 small tubular finger bones (phalanges). The finger bones are held together by various ligaments. The joint capsule around the finger joints are reinforced by three ligaments (two side ligaments and a ligament under (volar) the joint). The ligaments under the finger joints are reinforced by a small cartilage plate (fibrocartilago), that stabilizes the intermediate joint of the fingers (PIP-joints).

RIGHT PALM

Cause: In case of a blow, twist or over-stretching, a rupture can occur on the ligaments and cartilage discs (fibrocartilago), that surround the finger joints. In some a piece of bone can be torn off where the ligaments fasten on the side of the bone.

Symptoms: Ligament damage will typically cause a swelling of the joint and tenderness on the side of the joint which is aggravated if the joint is twisted from side to side. With damage to the cartilage disc (laesio fibrocartilaginis volaris) under the joint, the pain will be localized to the underside of the joint (volar) which is aggravated with passive over-stretching and maximal flexing of the joint.

Acute treatment: Click here.

Examination: With sudden powerful pain in a finger it is advisable to have the joint examined to ensure a correct diagnosis and treatment. The results are best if the diagnosis is made and the treatment is commenced immediately following the injury (article). A tearing of the ligament anchor on the side of the finger is occasionally visible on x-rays.

Treatment: The vast majority of ligament ruptures can be treated without surgery, while other ligament ruptures with clear laxity require surgery. It may be necessary to perform an x-ray, ultrasound scan (article 1) or an MR-scan (article 2). Damage to the cartilage disc is often treated with a splint on the finger for about 3 weeks, although not all physicians agree with this (article 3).

Rehabilitation: Fitness training in the form cycling and running along with rehabilitation according to the guidelines under rehabilitation, general can usually be commenced immediately. Once the pain is completely gone you can participate in sports, although handball, volleyball, basketball and similar activities should be avoided for a few additional weeks.

Bandage: It will often stabilise the joint if the damaged finger is taped to its neighbour (tape-instruction).

Complications: In the vast majority of cases the ligaments heal without complications. In some cases, particularly after a lesion of the cartilage disc under the joints, long-term discomfort can continue for as long as a year after the injury (article). In cases of persistent pain and lack of progress you should consult your doctor again.

RIGHT HAND’S BONES – PALM

Cause: With a blow, twist or fall on the hand a fracture can occur in the finger bones.

Symptoms: Sudden pain in the finger after a fall, twist or blow. Pain is aggravated upon maximal movement of the finger and upon applying direct pressure on the fracture. A visible angling of the finger can occasionally be seen.

Acute treatment: Click here.

Examination: Everyone with sudden powerful pains in a finger after a fall or blow should be examined by a doctor if the pain does not quickly abate. In case of visible angling of the finger, the medical examination should be acute. The fracture is usually visible on x-rays allowing the best treatment to be chosen accordingly.

Treatment: If there is dislocation of the finger bone, the fracture can be reset under local anaesthetic. Most fractures can be managed with relief and light bandaging, while others require a cast or surgery (article).

Rehabilitation: Fitness training in the form of cycling, running and rehabilitation according to the guidelines under rehabilitation, general can usually be started immediately. When the cast is removed you can commence training of the hand and arm. Thrusts or jabs with the hand (boxing, handball, volleyball and similar sports) should be avoided for an additional few weeks.

Bandage: The fracture will often be stabilized if the finger is taped to the neighbouring finger (tape-instruction). Individual plastic bandages can be made for use during sports activity after bone fractures.

Complications: In the vast majority of cases the fracture heals without complications although in some cases the healing can complicated. Therefore, in case of persistent pain and lack of progress, you should consult your doctor again.

Fracture of carpal bone in the wrist

FRACTURE OF CARPAL BONE IN THE WRIST

Diagnosis: FRACTURE OF CARPAL BONE IN THE WRIST
(Fractura ossis scaphoidei)


Anatomy:
The wrist bones consist of 8 carpal bones (ossa carpi), which along with the forearm bone (ulna) and the radius form the wrist. There are furthermore 5 metacarpus bones (ossa metacarpi) and a total of 14 finger bones (phalanges).

  14. Carpus

RIGHT HAND’S BONES – PALM

Cause: In case of blow or a fall where you attempt to protect yourself with the hand, a fracture can occur on the carpal bone on the thumb side, also called the navicular bone (os scaphoideum). Due to a poor blood supply to the bone a slow and complicated healing often occurs. For this reason it is crucial that treatment starts immediately after the fracture has occurred.

Symptoms: Sudden pain in the wrist on the thumb side following a fall or blow. The pain is aggravated by maximal movement in the wrist. The symptoms are often so modest that the athlete does not immediately consult a doctor. Many athletes misinterpret the symptoms as a sprained wrist, which can delay treatment and have unfortunate consequences in the long run.

Acute treatment: Click here.

Examination: Everyone with sudden powerful pain in the thumb side of the wrist, after a fall or blow, should always be examined by a doctor. In X-rays the fracture can usually (but not always) be seen. It can therefore be necessary to repeat the X-ray examination 14 days later, before a fracture can be ruled out with certainty.

Treatment: Plaster cast (article).

Rehabilitation: Once pain has decreased, fitness training in the form of cycling and running can be resumed according to the guidelines under rehabilitation, general. When the cast is removed rehabilitation of the hand and the arm can be started. Blows with the hand (boxing and similar activities) should be avoided for an additional couple of months.

Bandage: Individual plastic bandages can be manufactured for use during sports activity after bone fractures.

Complications: In the vast majority of cases the fracture heals without complications. In some a very slow healing may occur, causing a long break from sports activity. In other cases a decomposition of the bone (avascular bone necrosis) occurs, which increases the risk of degenerative arthritis changes in the carpus. It is not rare for a false joint (pseudoarthrosis) to form due to lack of healing (article). The risk of complications is greatest when the treatment is commenced a long time after the fracture occurred.
In case of lasting wrist pain and lack of progress you should therefore consult your physician again, despite earlier normal examination.

Specielt: As there is a risk that the injury can cause permanent disability, all cases should be reported to your insurance company.

Fracture of forearm bones in the wrist

FRACTURE OF FOREARM BONES IN THE WRIST

Diagnosis: FRACTURE OF FOREARM BONES IN THE WRIST

RIGHT WRIST – BACK OF THE HAND

Cause: A fracture can occur in the bones in instances of a blow or a fall on an outstretched arm. In adults the antebrachial bone often fractures close to the wrist, causing a characteristic fork shaped angling of the wrist (fractura Colles). In children fractures on the antebrachial bone is often localised to the growth zone on the radius (epifysiolysis radii).

Symptoms: Sudden pain in the forearm and pain conditioned constriction of movement of the arm after heavy load (fall). An angling of the lower arm is occasionally visible.

Acute treatment: Click here.

Examination: Sudden powerful pains in the arm, with movement constriction after a fall should always lead to medical examination. A fracture is usually visible in an X-ray examination, and the treatment can be determined based on the type of fracture.

Treatment: In cases of significant displacement or angling of the bones, the fracture is reset under anaesthesia, after which it is bandaged for a few weeks. With special types of fracture it may be necessary to stabilise the fracture surgically. It is important to commence rehabilitation of the hand as soon as the bandage is removed (article).

Rehabilitation: Once pain has diminished fitness training can be commenced in the form of cycling and running, together with rehabilitation according to the guidelines under rehabilitation, general. The rehabilitation is completely dependant on the type of fracture and treatment.

Bandage: It is possible to manufacture individual hard plastic bandages for the wrist and fingers for use during sports activity after bone fractures.

Complications: In the vast majority of cases the fracture heals without complications. In some a bad healing can occur, the blood and nerve supply to the arm can be affected, acute compartment syndrome. In case of lack of progress or a conspicuous amount of pain despite the hand being at rest, you should consult your doctor.
