Importance of the Hand
The hand is extremely complex and requires fine balance of all structures to function properly.We are able to manipulate our environment through the use of our handsFinger and hand injuries can be among the most devastating if not well cared for because we use our hands for hundreds of daily activities.
Bones of the Wrist and Hand
Bones of the wrist include: Distal radius, scaphoid, lunate, triquetrum,
pisiform, trapezium, trapezoid, capitate, and hamate
How do you remember the carpal bones? 5 metacarpals14 phalanges
Wrist JointsMade up of two compound joints
Radiocarpal and MidcarpalStability is provided by numerous ligamentsAllows for the following motions:
Flexion Extension Abduction: Radial deviation Adduction: Ulnar deviation
Hand JointsIntercarpal joints:
Stability provided by ligamentsCarpometacarpal joints:
Permit flexion, extension, abduction, adduction of metacarpals (MC)
Metacarpophalangeal joints (MCP)Interphalangeal joints, Proximal and Distal (PIP, DIP)
Convex proximal segment, concave distal segment
Allows flexion and extension
Convex-Concave Arrangement of Carpal Bones
Fascia of the HandPalmar fascia
Superficial - extension of transverse carpal ligament and palmaris longus tendon; goes to fingers
Deep - floor from thenar to hypothenar; serves to cushion and protect hand and maintain hand’s concavity
Dorsal fascia Two layers but less dense
Common tissue injuries, conditions
and surgical interventions
Referred PainC6, C7, C8 nerve roots terminate in the hand
Injury or entrapment of these nerves may occur anywhere along their course
Median Nerve- compression at the carpal tunnel
Ulnar nerve- compression in the ulnar tunnel
Where will the patient experience symptoms?
Carpal Tunnel Syndrome
Irritation of the synovial membranes around the tendons in the carpal tunnel This inflammation results in in pressure on the median nerveThe median nerve travels from the forearm into the hand through a 'tunnel' in your wristThe bottom and sides of this tunnel are formed by wrist bones and the top of the tunnel is covered by a strong band of connective tissue or ligament
Carpal Tunnel Syndrome
This tunnel also contains nine tendons that connect muscles to bones and bend your fingers and thumbThese tendons are covered with a lubricating membrane called synovium which may enlarge and swell under some circumstancesIf the swelling is sufficient it may cause the median nerve to be pressed up against this strong ligament which may result in numbness, tingling in your hand, clumsiness or pain, all classic signs of carpal tunnel syndrome Treatment:
Splinting, ROM/Stretches, modalities, isometrics exercises
Carpal Tunnel Syndrome
Carpal Tunnel Syndrome
Joint HypomobilityCommon causes:
Rheumatoid arthritis Degenerative joint disease Swan-neck deformity Boutonniere deformity
Joint HypomobilityProtection Phase
Control Pain and Protect Joints Patient Education Pain Management Splinting Activity modification
Maintain Joint and Tendon Mobility and Muscle Integrity PROM, AAROM or active AROM Tendon-gliding exercises Multi-angle muscle setting exercises
(isometrics)
Joint HypomobilityControlled Motion and Return to Function Phases
Increase Joint Play and Accessory Motions Joint mobilization techniques Improve joint tracking and pain-free motion Improve mobility, strength, and function Return to functional activities Conditioning exercises
Tendon-GlidingDesigned to maintain or develop free gliding between tendons and bones in the wrist, hand, and fingersAdhesions between various structures can become restrictive or incapacitatingThe most common tendon-gliding exercises are:
Flexor Tendon-Gliding Exercises Extensor Tendon-Gliding Exercises
Rheumatoid Arthritis (RA)
The joint’s synovium becomes inflamed and swollenSwollen tissues stretch supporting structures of the joints such as ligaments and tendons. As the support structures stretch out, the joints become deformed and unstable.
Treatment: Splinting, ROM, stabilization and modalities
Swan-Neck DeformityLaxity of the PIP joint
Hyperextension of the PIP and flexion of the DIP joints
Treatment: Splinting/ ROM/Stretch, strengthening and
modalities
Boutonnière DeformityAn injury to the tendons in the fingers that usually prevents the finger from fully extendingThe result is that the PIP of the injured finger is in a flexed position, while the DIP remains in a hyperextended positionThis is the characteristic shape of a boutonnière deformity
Treatment: Splinting/ ROM/Stretch, strengthening and
modalities
Joint Surgery and Postoperative Management
Goals of surgery: Relief of pain Restoration of normal or sufficient function of
the wrist and hand Correction of instability or deformity Restoration of ROM Improved strength of the wrist and fingers
Necessary for grasping and pinching
Joint Surgery and Postoperative Management
Common surgical interventions: Wrist arthroplasty Metacarpophalangeal implant arthroplasty Proximal interphalangeal implant
arthroplasty Carpometacarpal arthroplasty of the thumb Tendon rupture associated with RA:
Surgical and postoperative management
Trigger FingerCan occur in one or more fingers, and can occur at different times in different locations.
Trigger finger results from a discrepancy between the size of the tendon and the entrance to the tendon sheath. This discrepancy can be the result of localized inflammation or a nodular swelling on the tendon itself.
When the size discrepancy between the tendon and the tendon sheath reaches a critical point, the tendon will experience resistance from the tendon sheath. This is experienced as a snapping of the trigger finger when relaxing a fist.
Treatment: ROM/Stretches, Isometrics and modalities.
Trigger Finger
Dupuytren's Contracture
An abnormal thickening of tough tissue (fibrous layer) underneath the skin of the palm and fingersMay cause the fingers to flex Dupuytren's contracture is more common in men than in women
Treatment: Splinting/ ROM/Stretch, strengthening and
modalities.
Dupuytren's Contracture
FracturesImmobilized so ligaments of the joints are placed on stretch to reduce risk of contracture.Open reduction and internal fixation (ORIF) may be used with unstable fractures.Immobilization is used for only as many joints as necessary to stabilize fracture.Wrist fractures most commonly affect the hamate or pisiform.
Scaphoid FractureA fall on an outstretched arm often results in a fracture of the scaphoid bone in the wrist.This small bone is one of 8 carpal bones in the wrist.The scaphoid sits below the thumb, and is shaped like a kidney bean.This complex bone has a unique and limited blood supply that can be easily disrupted by a fracture.
Scaphoid FractureDue to poor blood supply, a fracture in the center of the bone can actually sever blood flow to the proximal portion of the bone. For this reason, scaphoid fractures need immediate diagnosis and treatment. Scaphoid fractures may heal very slowly or may not heal at all.
Treatment: Splinting, Isometrics and modalities
Scaphoid Fracture
Scaphoid Fracture
Colles' FractureA break at the distal aspect of the radiusThe radius is the most commonly broken bone in the armA Colles' fracture typically occurs when the individual lands on an outstretched hand
Treatment: Pain management, immobilization,
stretching, ROM activities, isometrics and modalities
Colles' Fracture
Repetitive Trauma Syndromes/Overuse Syndromes
TenosynovitisTendinitisTraumatic Lesions in the wrist and handSprainsLacerated flexor tendonsLacerated extensor tendons
Common Interventions for the Wrist and Hand
Techniques for Musculotendinous Mobility Tendon-gliding and tendon-blocking exercises Scar tissue mobilization for tendon adhesions Palmar fascia release
Flexibility and Stretching Guidelines
Apply joint mobilization before stretchingApply force precisely and in sequence from most distal to most proximal joint.When only one joint is stretched, others must be stabilized.Stretch one finger at a time.Wrist stretches begin with fingers and move to wrist.

Tendon-Gliding Exercises
Uses active muscle contraction and specific motions of the digits and wrist to maintain or develop mobility between connective tissue structures in the wrist and handThese are particularly important following immobilization when scar adhesions may have developedTendon-gliding exercises may also help develop coordinated movement
Flexor Tendon-Glide Exercises
Designed to maintain or develop free gliding between tendons and bones in the wrist, hand, and fingersFive positions:
Straight hand Hook fist Full fist Table top Straight fist
Hook Fist Position
Full Fist Position
Straight Fist Position
Extensor Tendon-Glide Exercises
Extensor tendons are more susceptible to adhesions than flexor tendonsSimilar movement patterns when compared with flexor tendon-gliding exercises
Extensor Tendon Gliding
Exercises to Develop and Improve Muscle Performance
Techniques used during the controlled motion phase and return to function phaseUsed to strengthen muscles of the wrist and hand
Examples of isometric exercises? Examples of isotonic exercises?
Safe return to functional activities
Plyometric & Activity-Specific Ex.
Plyometric exercises for the wrist and hand are similar to those used for shoulder and elbowActivity-specific exercises are determined by the demands of the patient’s sport and position or occupationProgress to specific patterns needed for ADL, job activities, hobbies, or recreational functionExercises should be adapted to meet the goals
