Int Orthop 27(suppl 1):2–6 Twenty Years of Experience with the Bernese Periacetabular Osteotomy for Residual Acetabular Dysplasia 1 2 Reinhold Ganz and Michael Leunig Summary. Residual acetabular dysplasia is known as the most frequent cause of early osteoarthritis of the hip. The degeneration starts with overload of the rim, leading to a variety of pathologies. This change may cause the femoral head to migrate further out of the socket, resulting in a loss of congruity and generating even higher pressure point loading, which ﬁnally leads to rapid destruction of the joint. It is well accepted today that the surgical increase of the load transmission area can slow down this process of destruction and postpone total hip replacement (THR) substantially. Among the different techniques available, reorientation procedures allow for the most physiological correction of the joint mechanics. Our proposition is a reorientation procedure, which was ﬁrst executed in 1984. Under the name of the Bernese periacetabular osteotomy, the technique has gained popularity, especially in North America. Our 20 years’ expe- rience performing this osteotomy through a modiﬁed Smith-Peterson approach without dissection of the abductors has clearly shown that confound appreciation of joint mechanics is the key to a successful result. Addressing acetabular retroversion and an insufﬁcient femoral head/neck offset has helped to avoid postosteotomy impingement and signiﬁcantly improved our results. Today, in our armentarium of surgical techniques to preserve the natural hip joint, the periacetabular osteotomy leads to the most predictable results.

It is well accepted today that surgical increase of the local transmission area and a more even load transmission can slow the process of destruction and postpone total hip replacement substantially. Among the different techniques available, reori- entation procedures allow for the most physiological correction of the joint mechan- ics. Based on limitations with several of the former techniques (Table 1), we deﬁned in 1983 the aspects to be achieved with a new technique as follows: optimal correction including version and medialization of the acetabular fragment; a single approach to avoid repositioning of the patient during the procedure; easy ﬁxation of the fragment allowing for early ambulation; and unlimited access to the joint to treat intracapsular pathologies without the potential risk of avascular necrosis of the acetabular fragment. Finally, the new technique should allow major bilateral correction without narrowing of the birth canal because most of the patients are females of reproductive age.
Unless people themselves choose to use an ambulation aid—or at least give it a solid try—they often won’t use it properly and get little beneﬁt purchase zudena 100 mg otc erectile dysfunction venous leak treatment, conﬁrming their original objections buy 100mg zudena with visa erectile dysfunction 42. Some people agree to carry the ambu- lation aid but won’t let it touch the ﬂoor, defeating the purpose. The phys- ical therapist Gary McNamara ﬁnds, Until they’ve taken a ﬁrst step and realize that it’s going to take change to create change, you can’t do anything. You go to some- one’s home and they say, “Yeah, I’ve fallen and my doctor told you to come. They’re convinced that they’re stuck in this rut and there’s nothing they can do. There’s a lot of preconceived notions in their head about assistive devices and what they mean. The psychologist Rhonda Olkin (1999, 285) argues that acceptance of assistive technologies, such as mobility aids, requires that they “be per- ceived as enablers of activities and functions that would otherwise be diffi- cult or impossible. Since mobility aids are visible, family members often hold strong opin- ions, and long-established familial dynamics come into play. Sometimes “a family might resist the implications of an AT and insist that the family member rely on his or her own limited facilities, despite the drain on per- sonal energy and emotional resources” (Olkin 1999, 291). I heard this from younger women whose husbands became deeply disturbed when their wives used mobility aids. The husbands do not outright forbid it, recogniz- ing their wives’ needs. Nevertheless, the husbands are terriﬁed by the im- plications—presumed permanent debility and inevitable downward spiral. Other times, family members are persistent advocates, and physicians en- list their help to persuade patients. They try to get patients to use the device, but they don’t always succeed. Johnny Baker navigates delicate terrain between his patients and their family members. Although family members want his professional opinion to validate their positions, Dr. Baker simply doesn’t know exactly what is right: after all, little scientiﬁc evidence exists to guide decisions about ambulation aids. Frequently there’s a family member who says, “Mom does ﬁne here in your examining room, but she totters around at home and I’m concerned about her. Then I try to redirect things to the patient: “How do you respond to what your daughter’s saying? The family member usually wants more assistance than the patient has accepted—like moving from a cane to a walker—and wants to go home and quote the doc- tor: “The doctor said you have to do this. But whether this person who’s using a cane would be better off with a walker, I don’t know. If I can get the patient and family mem- ber to agree with each other, I’ll assume that’s what’s right. Baker and other clinicians noted, the symbolism of speciﬁc am- bulation aids is off-putting. Clinician interviewees suggest that carved or painted canes and colorful walkers are more palatable, ornamental as well as practical. Each person needs to ﬁnd a way to make equipment less of a barrier with other people. The Halperns’ house was an obstacle course, jumbled boxes and stacked papers strewn among sheet-draped furniture. Esther Halpern doesn’t like that walker, rejecting it immediately after the physical therapist delivered it. Halpern loves her “carriage”—an aluminum walker with four wide gray rubber Ambulation Aids / 191 wheels, brakes on each handlebar, and a stretched cloth seat.
