DAMASCUS HOSPITAL
Dr.MHD BASHAR ALBOSHI
Definition:
Developemental?!! DDH is a disorder that evolves over time.
The left hip> right hip.
bilateral hips> right hip alone.
Etiology:
تداخل عدة عوامل مشتركة
الرخاوة الرباطية (1)
الرحم ) (2) داخل المقعدية .(الوضعية
Generalized familial
hyperlaxity
Etiology:
(3).وضعية البسط التام للوركين بعد الوالدة(4):العرق
أعلى لدى القوقاز واألمريكان المحليين. أقل عند السود واألسيويين
Associated Conditions
Torticollis (15% have DDH) Metatarsus Adductus(1.5-10%have DDH)
PATHOPHYSIOLOGY( NORMAL HIP DEVELOPMENT):
The hyaline cartilage
( triradiate cartilages)
Pathophysiology (secondary obstacles):
الشحمية (.pulvinar thickens)النسج
) ومتطاول ) متسمك المدور الرباط) ( متضخم المعترض الرباط
) الرملية) الساعة شكل المحفظة
Iliopsoas
Fatty tissue(pulvinar thickens).
Teres ligament (elongated and thickened)
Docking the head
•Labrum: Cartilaginous acetabular lip.
•Neolimbus:a ridge of thickened articular cartilage
dislocatedsubluxated
Transverse ligament )hypertrophic(
Hourglass shape of the capsule by the iliopsoas
tendon
Pathophysiology (secondary obstacles):
Shortened of pelvifemoral muscles
progressive

teardrop body:
Losees its convexity
Wider.
The presence of a teardrop at 6 months after reduction predicted a satisfactory outcome in 93% of hips.

Screening Criteria
all babies with the risk factors
ultrasound + clinical examination
Neonate: Pavlic harness ))6 weeks((.
1 to 6 months: Pavlic harness)) 6 weeks(( after hip reduces.
6 to18 months: traction?
)1( Closed reduction) cast 3 months(
)2(Open reduction) unsuccessful closed reduction(
< 12 months )Medial approach(
> 12 months )anterolateral approach(
18 to 24 months: Trial of closed reduction?
Or primary open reduction )anterolateral approach(
)+/-A salter osteotomy (
24 months to 6 years: primary open reduction )anterolateral approach( + femoral shortening . ))+/-A salter osteotomy ((
TREATMENT
TREATMENT( NEONATE-6 MONTHS)
PAVLIK harness for 6 weeks after hip reduction
•Hip flexion)120degrees(.
TREATMENT( NEONATE-6 MONTHS)
----- + بعد إيكو اإليكو على شذوذ وليد عند طبيعي سريري فحص6--- --- عالج شذوذ أسابيع
بعد خلع حدث .4-3إذا ------- مفتوح أو مغلق رد أسابيع
TREATMENT( 6-18 MONTHS)
Skin traction for 2 – 3 weeks
90D
TREATMENT( 6-18 MONTHS)
open reduction if closed reduction is unsuccessful !
Closed reduction
(spica cast for 3 mo). >90D flextion
abduction30-40D
Internal rotation 10-15D
TREATMENT(AFTER 18 MONTHS)
Primary open reduction
OPEN REDUCTION
Medial Approach:

•Prefer>1 yrs.
•5-7 cm
•1cm distal and parellel to the inguinal crease.
•Centered over the anterior margin of the adductor longus
•If necessary can ligate and section saphenous vein.
•The adductor longus is sectioned at its origin and reflected distally.
•At the anterior margin of the adductor longus the pectineus are identified.
•)A( the hip is approached anterior to the pectineus, between the muscle and the femoral sheath.
•Expose the iliopsoas tendon at its insertion to the lesser trochanter.
•The femoral circumflex vessels retracted laterally.
•)B(the hip approach posterior and medial to the pectineus .
•Flexion:100 degrees.
•Abduction:30 degrees
•Cast: 3 months.
•Skin incision is oblique)bikini incision).((excellent exposure and cosmesis))
•Begin 2/3 the distance from greater trochanter to the iliac crest,crosses the inferior spine,and extends 1-2 cm beyond the inferior spine.
OPEN REDUCTION(Anterior Approach Smith-Petersen):
Begin the incision at the middle of the iliac crest or, for a larger exposure, as far posteriorly on the crest as desired.
•Must determine:
)1( Depth of acetabulum and inclination of its roof.
)2( Shape of femoral head ,and smoothness ,cartilage.
)3( Degree of antetorsion of femoral neck.
)4( Stability of hip after reduction.
•Suture:
iliac apophsis.
rectus femoris,sartorius to their origins
•Cast: 60-70 flexion
45 D abduction
20-30 medial rotation
