Term
• Volkman’s Ischemic Contracture
Definition
o Increased pressure within the compartment of forearm
o Caused by direct trauma, tight cast, swelling
o Decreased capillary refill, possible development of contracture, may have nerve entrapment
o Tx: take off cast or fasciotomy (within 6 hours muscle death occurs)
o BEST EXAM FINDINGS:
Hot, overly painful, increased girth
Term
• Mallet Finger
Definition
o Caused by hyperflexion of distal phalanx with extensor tendon under tension; may have avulsion or base of distal phalanx or ruptured tendon just proximal to insertion (DIP drops volarly cause no longer has an extensor attachment)
o Tx: splinting to neutral or slight hyperextension for 6-8 weeks with no flexion of DIP joint; if flexion occurs, 6 weeks starts again; maintain ROM at other joints; when healed, AROM but no attempts to passively flex finger for 4 weeks; Blocking exercises to encourage flexor digitorum profundus to pull through; stabilize PIP when performing exercise
o BEST EXAM FINDINGS:
 No active extension of DIP
 Full passive extension of DIP
Term
• Heberdens and Bouchard’s Nodes
Definition
Herbeden
- dorsal surface of DIP with OA
Bouchard’s
- dorsal surface of PIP with OA
Term
• Swan Neck Deformity
Definition
o Flexion of MCP and DIP and Extension of PIP
o Caused by intrinsic muscle contracture or tear of volar plate; common with RA
Term
• Boutonniere Deformity
Definition
o Extension of MCP and DIP and Flexion of PIP
o Caused by a tear or rupture or central tendon slip of extensor hood; common with RA
o Rupture central slip  extensor force to dip  PIP joint buckles into flexion through hood  two central bands on top and exaggerate position
o Tx: splinting PIP in full extension for 6 weeks; exercises following healing – active assisted PIP extension and maximal active forced flexion of DIP while PIP is held at 0 degrees two stretch lateral bands and oblique retinacular l to physiologic length  continue splinting for 2-4 weeks when not exercising
Term
• Trigger Finger
Definition
lubrication  inflammation of tendon (tendonitis)  inflammation of sheath (tenosynovitis)
o Causes sticking of tendon with flexion; typically 3rd or 4th finger; women more than men; mid age, RA
o May be seen in athletes after holding a racquet, golf club, or bat with resulting inflammation
o Pain and tenderness from volar MCP to PIP with intermittent triggering or snapping of the finger; digit often locks in flexion when pt arises from sleep and requires passive assist to fully extend the finger
o Tx: taping or splinting finger in extension at night; NSAIDs, active IP flexion and tendon gliding exercises on an hourly basis; US, soft tissue mobilization, ice; may need surgical release
o BEST EXAM FINDINGS:
 Digit won’t extend actively or passively (depending upon extent)
Term
• Bennett’s Fracture
Definition
o Fx/dislocation injury @ the 1st CMC joint
o Caused by axial force applied to partially flexed thumb; dislocation of metacarpal base while leaving piece behind with trapezium
o BEST EXAM FINDINGS:
radiograph
o Rx:
1) address hypomobility and muscle tightness/weakness after immob
2) If have capsule laxity after the fracture, strengthen surrounding muscle
Term
• Scaphoid Fracture
Definition
o Caused by falling on open hand; wrist extended with wrist radially deviated
o Complications: AVN, non-union, DJD (no muscle attachments, covered with articular cartilage, blood supply from distal pole); pseudoarthrosis and non-union after 6 months if no medical attention
o BEST EXAM FINDINGS:
 PFT in anatomical snuff box
 PFC – minimal swelling
 AROM – painful with wrist extension and radial deviation (same way injured)
 (healing right on T2 MRI, after dark line on T1 and T2, with fluid on T2 in pseudorthrosis)
o Rx
Med: immob for <6 weeks, circular disc of bone stimulator placement, 3 mos healing
PT: treat impairments found after immob; cast, splint 2-4 weeks after cast, only off for exercises, passive ROM to wrist and thumb with putty squeezes
Term
• Dupuytren’s Contracture
Definition
o Contracture of palmar aponeurosis with insidious onset with fibroblast proliferation producing change from noncontractile to contractile tissue; small node in palm of hand is initial symptom; further contraction of palmar fascia leads to flexion contracture of the fingers, especially ring and little fingers; contracture of MCP and PIP
o More common with combo of alcoholism, liver disorders, DM, epilepsy; may appear as a late sequela to shoulder-hand syndrome after MI; Men after age of 30 and women after 45

o Insidious onset unless resulting from fracture, dislocation, swelling of the wrist
o Pt may c/o waking up at night because of the pain; increase in symptoms during static positioning
o Differential Diagnosis:
 C6 or C7 nerve root involvement; If nerve root involvement, the pt is rarely awakened at night due to parasthesia and use of the hand does not bring on symptoms
 Thoracis Outlet Syndrome: parasthesia may involve the entire hand or pt isn’t sure which fingers are affected; OR, may just be ulnar border b/c of involvement of the lower cord
o Objective tests may reveal thenar weakness, sensory deficit, positive Tinel’s, modified Phalen’s and reverse Phalen’s, ULTT
o Tx: NSAIDs, treat the cause, modify activities (grip, ergonomics, etc), nerve glides, splint
o BEST EXAM FINDINGS:
 Paresthesia in median nerve distribution
 Muscle weakness/motor changes in median nerve
 C/o night pain (pain is irritation, tingling is regeneration with tinels)
