DR AMJAD ALI
PGR ORTHOPEDIC UNIT 2
DEVELOPMENTAL
DYSPLASIA OF THE HIP
ETIOLOGY AND EPIDEMIOLOGY
• INCIDENCE OF DDH IS 1 IN 1000 LIVE BIRTHS.
• FEMALE TO MALE RATIO IS 4 : 1
• POSITIVE FAMILY HISTORY
• FIRSTBORN CHILD
• MORE COMMON IN LEFT HIP
• BREECH DELIEVERY
• LIGAMENTOUS LAXITY DUE TO MATERNAL HORMONE
RELAXIN
CLINICAL PRESENTATION AND DIAGNOSIS
IN NEWBORNS ( < 6 MONTHS OLD):
• CLINICAL EXAMINATION IN NEWBORN IS DONE WITH
POSITIVE HISTORY OF RISK FACTORS.
• DYNAMIC ULTRASOUND IS USEFUL IN DIAGNOSIS OF DDH
IN NEONATES THAN XRAY AS FEMORAL HEAD
OOSIFICATION OCCURS AT AGE 4-6 MONTHS.
IN NEONATES ON PHYSICAL EXAMINATION
ORTOLANI TEST IS +ve (elevation and abduction of
femur relocates a dislocated hip)
BARLOW TEST IS +Ve (adduction and depression of
femur dislocates hip)
CLINICAL MANIFESTATION
RADIOGRAPHY IS USED IN INFANTS AND
WALKING AGE GROUPS FOR DIAGNOSIS
OF DDH AS OSSIFICATION OF FEMORAL
HEAD HAS COMPLETED.
TREATMENT:
• THE EARLIER THE BETTER.
• SPECIFIC TREATMENT DEPENDS ON CHILD AGE.
• BEST TIME FOR TREATMENT IS NEWBORN PERIOD.
• THE GOALS IN THE MANAGEMENT OF DDH ARE TO
OBTAIN A CONCENTRIC REDUCTION OF THE FEMORAL
HEAD WITHIN THE ACETABULUM TO PROVIDE THE
OPTIMAL ENVIRONMENT FOR THE NORMAL DEVELOPMNT
OF BOTH THE FEMRAL HEAD AND ACETABULUM.
• THE LATER THE DIAGNOSIS OF DDH IS MADE,MORE
DIFFICULT IS TO ACHIEVE THESE GOALS AND THE IS
LESS POTENTIAL FOR ACTETABULAR AND PROXIMAL
FEMORAL REMODELING.
TREATMENT 1-6 MONTHS :
• FIRST CHOICE IS PAVLIK HARNESS
BRACE.
• IT PREVENTS HIP EXTENSION AND
ADDUCTION BUT ALLOWS FLEXION
AND ABDUCTION WHICH LEAD TO
REDUCTION AND STABILIZATION.
• PAVLIK HARNESS IS WORN 23 HOURS A
DAY FOR 6 WEEKS AFTER REDUCTION,
AND FOR NIGHT ONLY FOR NEXT 6-8
WEEEKS.
• PATIENT IS FOLLOWED UP FOR EVERY
TWO WEEK INTERVAL AND STRAPS ARE
ADJUSTED TO ACCOMMODATE GROWTH.
• USG IS USED FOR FOLLOW UP TO VERIFY
POSITION OF HIP.
• COMPLICATIONS OF PEVLIK HARNESS INCLUDE AVN,
FEMORAL NERVE NEUROPATHY.FAILURE OF
REDUCTION.
• IF ANY COMPLICATION OCCURS DISCONTINUE
BRACE.
• CLOSE REDUCTION AND SPICA CASTING SHOULD BE
CONSIDERED
TREATMENT 6-18 MONTHS:
• CLOSE REDUCTION AND SPICA CAST IMMOBILIZATION
IS RECOMMENDED IN THIS AGE GROUP.
• SKIN TRACTION IS APPLIED 1 -2 WEEKS BEFORE
REDUCTION.
• PERCUTANEOUS OR OPEN ADDUCTOR TENOTOMY
CAN BE DONE FOR ADDUCTOR CONTRACTURE.
• SPICA CAST IS APPLIED WITH HIP JOINT IN 95 DEGREE
OF FLEXION AND 40-45 DEGREE OF ABDUCTION.
• SPICA CAST IS CONTINUED FOR 3-4 MONTHS.
• RADIOGRAPH IS USED TO ENSURE FEMORAL
HEAD IS REDUCED ANATMOMICALY IN TO
ACETABULUM.
• IF CLOSE REDUCTION FAILS OPEN REDUCTION
IS CONSIDERED.
TREATMENT 18 MONTHS ---3YEARS
• OPEN REDUCTION IS RECOMMENDED IN
THIS GROUP,
• ANTERIOR APPROACH (SOMERVILLE)
• MEDIAL (LUDLOFF)
• SPICA CAST IS APPLIED AFTER REDUCTION
FOR 3-4 MONTHS.
SOMERVILLE APPROACH
TREATMENT IN 3 YEARS AND ABOVE
IN THIS AGE GROUP STRUCTURAL ALTERATIONS IN
FEMORAL HEAD AND ACETABULUM HAVE OCCURRED.SO
IN ADDITION TO OPEN REDUCTION THEY NEED
• FEMORAL OSTEOTOMY(VARUS DERORATIONAL
OSTEOTOMY OF FEMUR)
• FEMORAL SHORTENING
• PEVLIC OSTEOTOMIES (SALTER ,PAMBERTON).
THANK YOU
