Abstract:

Minimally invasive surgical techniques is an important component of modernday hip replacements. The most significant progressin the evolution of total hipreplacement is that the procedure can be done with much less invasive techniques whichallow the patientto recover and therefore mobilise early. These techniques requireminimum handling to prevent damage to periarticular soft tissuesand preservation ofbone substance to the maximum extent possible,which helps conserve bone mass andavoid damage to soft tissues, which allows faster restoration of hip function.


Introduction:

I had devised an Approach to the Hip Joint `Modified Posterior Approach to the Hip Joint’https://www.amazon.com/Modified-Posterior-Approach-HipJoint/dp/3330336870/ref=sr_1_1?s=books&ie=UTF8&qid=1503829887&sr=1-1&keywords=lambert+academic+publishingmodified+posterior+approach+to+the+hip+joint,in 1981, along with the mentorship of aBiomedical Engineer Dr. Martin Elloy,PhD attached, to the University of Liverpool,UK,at a timewhen there were considerable reports of dislocation of the hip joint using the conventionalposterior Approach as described by Austin Moore in 1957(Ref.no.1).

With interactions with Dr.John O’Donnell of Australia,who is extremelycomfortable sayingthat I continue to use DAA for my hip replacements, and I have been very happy with it that Icannot imagine changing to any other approach now.I developed an interest in the DirectAnterior Approach to the Hip Joint and have used in initially in Hemiarthroplasty in a fewcases with a radical change in my thinking of this Approach,which is helpful to the patienttremendously,in that there is no need to osteotomise the greater trochanter and henceavoids any complications related to the union of the greater trochanter,such as non-union orfibrous union,but most importantly prevents dislocation of the Hip Joint which was the mainpurpose of me devising the Modified Posterior Approach to the Hip Joint,which I had beenusing till today. Due to these multiple simple advantages offered by this Approach,I wouldnot hesitate to recommend this Direct Anterior Approach to the Hip Joint to the newergeneration of Orthopaedic Surgeons wherever feasible. The most effective surgical approach for the Hip Joint remains controversial,as the Hip jointis likened to a motorwayroundabout with plenty of different approaches and exits. Thereare more than100 different approaches to the Hip Joint de scribed in literature (Fig.no.1)

Direct anterior approach (DAA) has become popular in thUnitedstates of America for pastone decade as “minimally invasive muscle sparing approach” The first description(Ref.no.3) of the direct anterior approach to the hip joint(Fig.no.2)

Figure 2: Hueter’s original publicationwhich provides an excellent exposure to the acetabulum, in primary or a revision total hiparthroplasty,whichIn contrast with conventional techniques, and hence direct anteriorapproaches (DAA) has gained popularity among theorthopaedic hip surgeons and patientsfor earlier recovery and mobilization.

This has progressed to such a point that some patients are ableto have their surgery doneas an outpatient procedure without any hospital admission,as mentioned in my book “HipJoint inAdults:Advances and Developments” https://www.crcpress. com/Hip-Joint-inAdults-Advances-and-Developments/Iyer/p/ book/9789814774727 in chapter 18 as ``Total hip in a day, setup and early experiencesin outpatient hip surgery”,by Dr. med. Manfred Krieger and and Dr.med. Ilan Elias,Wiesbaden,FrankfurtGermany(Ref.no.4).This is achapter written wherein the Total Hip canbe done as an outpatientprocedure without any in-patient addmission(Fig.no.3) on selectedpatients as a day case,without any fear of dislocation.

Figure 3: Intra-op single incision anterior approach(Courtesy:Figure reproduced with kindpermission of Dr. ILAN ELIAS and Dr. MANFRED KRIEGER,Frankfurt, Germany) The Direct Anterior Approach can be helpful in

  1. Outpatient procedure as in certain advanced centres in Frankfurt,Germany.
  2. The Direct Anterior Approach in Hemiarthroplasty.
  3. Direct Anterior Approach in Primary Total Hip Arthroplasty.
  4. Direct Anterior Approach in Revision Hip Arthroplasty In fact,I am particularly happy by its use immensely so much sothat I am coming out with asmall book on the `The Direct AnteriorAproach to the Hip Joint’ by Lambert AcademicPublishing,Germany in early 2018

Dr.John O’Donnell of Australia who uses a fracture table(Fig.no.4) for DAA(Ref.no.5)

Figure 4: Patient positioned for right Total Hip Replacement(“Courtesy:With the kindpermission of Dr.John O D’onnell,Associate Professor,Hip Arthroscopy Australia)Direct anterior hip replacement is considered as a minimally invasive surgical technique. Theanteriorapproach for hip replacement is a tissue-sparing technique designed to followboth an intermuscular and an internervous path(Fig.no.5)

Figure 5:The approach is both intermuscular and interneural((With kind permissionMedacta,through Dr.John O’Donnell.Associate Professor, Hip ArthroscopyAustralia).The blue line is the line of the approach, passing between the Rectusfemoris and Sartorius, innervated by the Femoral nerve, and the TFL and Glutealemuscles, innervated by the Gluteal nerves.

This approach provides a direct visualization of the acetabulum and the anterioriliac spine landmarks to allow reference for appropriatecup positioning as Itutilizes anterior internervous and intermuscularplane.I have tried to get accustomed to this DAA by initially as I was accustommedtothe Modified Posterior Aproach to the Hip Joint andby doing a few cases of Hemiarthroplasty by the DAA as shown in figure 3,and am fully convinced ofthe usefulness of this Approach tothe Hip Joint for the younger generation ofOrthopaedic Surgeonsin the world,because of multiple advantages.Dr.John O D’onnell,Associate Professor, Hip Arthroscopy Australiais also theConvener and Host, Melbourne ISHA ASM 2018,andwould encourage allOrthopaedic Surgeons worldwide to attend thesame.
