EXT.มานิดา โรจนเสถียร
EXTERN CONFERENCE
• PP : หญิงไทย อายุ 59 ปี
• CC : ล้มมือขวายันพื้นมา 2 วัน
• PI : 2วันก่อน ลื่นล้ม ข้อมือขวากระแทกพื้น มีปวด บวม ข้อมือขวาผิดรูป จึงไปรพช.
ได้ใส่เฝือกที่มือขวา หลังจากนั้นยังมีปวดที่ข้อมือขวาอยู่
• Past illness : U/D – HT
: no food/drug allergy
PHYSICAL EXAMINATION
• ABCD - pass
• Vital signs : T36.6 PR 68 bpm BP 185/94 mmHg RR 20
• GA : A middle-age Thai woman, alert, good
consciousness, not pale
• MSK : Rt. Wrist – no wound,
mild swelling, marked
tenderness, limited ROM,
can extend thumb, can do
good, OK, byebye signs,
intact PPS, cap refill< 2sec
INVESTIGATION
• Film Rt. Wrist AP, Lateral
DIAGNOSIS
•Closed fracture Rt.distal radius
(colles’s fracture)
DISTAL END RADIUS
FRACTURE(DER)
• Most common orthopedic injury
• Most common mechanism : Falling On an Outstretched
Hand(FOOSH)
• Bimodal distribution
• younger patients - high energy
• older patients - low energy / falls
• 50% intra-articular
• Associated injuries : DRUJ, radial styloid fx (higher energy), soft tissue
injuries in (TFCC , scapholunate ligament, lunotriquetral ligament)
• Osteoporosis
• high incidence of distal radius fractures in women >50
• distal radius fractures are a predictor of subsequent fractures
• DEXA scan is recommended in woman with a distal radius fracture
Distal End Radius Fracture(DER)
FERNANDEZ CLASSIFICATION
• Type I,III - most are stable
• Type II,IV,V-unstable
TYPE I
BENDING
Colles’
s
Barton’s Chauffer’s
Fx dislocation of
radiocarpal joint with intra-
articular fx involving the
volar or dorsal lip.
Smith’
s
TYPE II
SHEARING
INDICATION FOR SURGERY
1.Unstable
-type II,IV,V and some of type
I, III
-Lafontaine criteria >=3/5
-displacement after casting
3.Unacceptable
alignment
Radial inclination <15
Shortening>5mm
Dorsal tilt > 10
Articular step off /gap
>2mm
4. Open fx
2.Irreducible Fx
-Double die punch
-Displaced comminute
posteromedial fragment
-Articular step off > 2 mm
-Severe comminution
-Shortening > 5mm
DIE PUNCH
Lafontaine criteria
• Age> 60
• Ulnar styloid Fx
• Dorsal comminution
• Intraarticular Fx
• Dorsal angulation >20
RADIOGRAPHS
CONSERVATIVE TX
-> CLOSED REDUCTION
WITH SHORT ARM SLAB
• 1.Hematoma block
2.CLOSED REDUCTION
+ คลาหาstepping
Volar flexion 15-20
Ulnar deviation
Pronation
Traction
• 3. short arm AP slab with 3 point molding
• 4.film wrist AP, lateral
• 5.F/U: 1-2 wk. ประเมินอาการบวม ,complication ,เปลี่ยนเป็น short arm
cast
: 6 wk. ถอดcast if no complication
POST REDUCTION
RADIAL HEIGHT
Post reduction
RADIAL INCLINATION
Post reduction
Post reduction
VOLAR TILT
ADVICE
• ให้ระดับมืออยู่เหนือหัวใจ เวลานอนควรวางมือบนหมอนหรือวางบนหน้าอก
• ให้ขยับข้ออื่นๆที่ไม่ได้immobilize
COMPLICATIONS
• Median nerve neuropathy (CTS)
• Ulnar nerve neuropathy (in DRUJ injuries)
• EPL rupture
• Radiocarpal arthrosis (in articular stepoff > 1-2 mm)
• Malunion and Nonunion
• ECU or EDM entrapment (in DRUJ injury)
• Compartment syndrome
• RSD/CRPS (vitamin C supplementation is
reccommended in postop)
