Austin Moore Hip Prosthesis Surgical Technique

Confirm that a hemi-arthroplasty is indicated.

The patient is positioned and prepared on the operating table in the usual manner. Expose the hip joint using your preferred surgical approach for hemi-arthroplasty.

Following exposure of the hip, cut the femoral neck. In most individuals an appropriate level of neck resection lies along a line drawn from a point medially mid-way between the upper margin of the lesser trochanter and inferior aspect of the head, to a point laterally at the base of the neck.

If the neck is cut too long, the leg will be lengthened, and the hip will be tight and difficult to reduce. The converse will be the case if the cut is too low, and the hip may be unstable. The neck cut may need to be modified a little higher or lower in valgus or varus hips, respectively.

Remove and measure the femoral head or alternatively use an appropriate instrument to measure the size of the acetabulum. Select an Austin Moore Hip Prosthesis with a femoral head of the same size.

Ensuring the gluteus maximus tendon is retracted and protected, a box chisel is used to open the proximal femur. This should be positioned laterally and posteriorly to gain exposure in line with the femoral canal.

Proximal femur preparation is made with the femoral rasp. This should be done by hand unless the bone is unusually hard, as using a hammer risks fracturing a fragile osteopenic femur.

The rasp should be inserted with the required amount of anteversion: typically this is between 0° and 20° depending on the preferred approach. The rasp should be inserted to a depth where the top cutting teeth line up with the neck resection line.

Following rasping, insert the definitive stem to ensure correct fit, seating and alignment can be achieved. Trim the neck if required to allow the collar of the prosthesis to sit flush. Confirm version is correct (see step 5). A trial reduction can be performed if required.

NB If performing a trial reduction, take great care when re-dislocating the hip. A swab around the neck of the prosthesis or a bone hook should be used to help dislocate and deliver the femoral head out of the acetabulum. Undue torsional force applied through the leg can fracture an osteoporotic femur.

The stem (corresponding to the measured size in Step 3) is inserted with the Femoral Head Driver until the collar of the prosthesis reaches the neck resection line on the medial calcar.

Ensure that the acetabulum is clear of any bone fragments or soft tissue before reducing the hip. Confirm stability and a concentric reduction before layered wound closure.

The general post-operative management of the patient should follow the normal protocols of the operating surgeon and the institution in which the surgery was performed.

Austin Moore Hip Prosthesis Contraindications

Contraindications may be qualified or total, and need to be taken into consideration when evaluating the prognosis in each case. Alternative management techniques may need to be considered under the following conditions:

  • Acute or chronic infections, either local or systemic.
  • Local or systemic accurate or chronic inflammation.
  • Serve muscular, nervous or vascular disease endangering the affected area.
  • Defective bone structures, which would impede adequate anchoring of the implant.
  • All associated diseases which could endanger the function and success of the implant.

Warnings and Precautionary for Austin Moore Hip Prosthesis

Before using Austin Moore Hip Prosthesis, the surgeon and ancillary staff should study the safety information in these instructions, as well as any product-specific information in the product description, surgical procedures and/or brochures.

Austin Moore is made from medical grade materials and are designed, constructed and produced with utmost care. These quality Austin Moore Hip assure best working results provided they are used in the proper manner. Therefore, the following instructions for use and safety recommendations must be observed.

Improper use of  Austin Moore can lead to damage to the tissue, premature wear, destruction of the instruments and injury to the operator, patients or other persons.

It is vital for the operating surgeon to take an active role in the medical management of their patients. The surgeon should thoroughly understand all aspects of the surgical procedure and instruments including their limitations. Care in appropriate selection and proper use of surgical instruments is the responsibility of the surgeon and the surgical team. Adequate surgical training should be completed before use of implants.

Factors which could impair the success of the operation:

  • Allergies to implanted materials.
  • Localized bone tumours.
  • Osteoporosis or osteomalacia.
  • System disease and metabolic disturbances.
  • Alcohol and drug abuse.
  • Physical activities involving excessive shocks, whereby the implant is exposed to blows and/or excessive loading.
  • Patients who are mentally unable to understand and comply with the doctor’s instructions.
  • Poor general health.

Possible Adverse Effects

The following adverse effects are the most common resulting from implantation:

  • Loosening of the Austin Moore Hip, which may result from cyclic loading of the fixation site and/or tissue reaction of the implant.
  • Early and late infection.
  • Further bone fracture resulting from unusual stress or weakened bone substance.
  • Temporary or chronic neural damage resulting from pressure or hematomata.
  • Wound hematomas and delayed wound healing.
  • Vascular disease including venal thrombosis, pulmonary embolism and cardiac arrest.
  • Heterotopic ossification.
  • Pain and discomfort due to presence of the Austin Moore Hip Prosthesis.
  • Mechanical failure of the implant, including bending, loosening or breakage.
  • Migration of implant resulting in injury.

Preoperative Planning for Austin Moore Hip Prosthesis

The operating planning is carried out following a thorough clinical evaluation of the patient, Also, x-rays must be taken to allow a clear indication of the bony anatomy and associated deformities. At the time of the operation, the corresponding implantation instruments in addition to a complete size of Austin Moore Hip Prosthesis must be available.

The clinician should discuss with the patient the possible risks and complications associated with the use of implants. It is important to determine pre-operatively whether the patient is allergic to any of the implant materials. Also, the patient needs to be informed that the performance of the device cannot be guaranteed as complications can affect the life expectancy of the device.

Austin Moore Hip Prosthesis Precautions

  • Confirm functionality of instruments and check for wear during reprocessing. Replace worn or damaged instruments prior to use.
  • It is recommended to use the instruments identified for this Austin Moore Hip Prosthesis.
  • Handle devices with care and dispose worn bone cutting instruments in a sharps container.
  • Always irrigate and apply suction for removal of debris potentially generated during implantation or removal.

Austin Moore Hip Prosthesis Warnings

  • Austin Moore Hip Prosthesis can break during use (when subjected to excessive forces). While the surgeon must make the final decision on removal of the broken part based on associated risk in doing so, we recommend that whenever possible and practical for the individual patient, the broken part should be removed. Be aware that implants are not as strong as native bone. Implants subjected to substantial loads may fail.
  • Instruments, screws and cut plates may have sharp edges or moving joints that may pinch or tear user’s glove or skin.
  • Take care to remove all fragments that are not fixated during the surgery.
  • While the surgeon must make the final decision on implant removal, we recommend that whenever possible and practical for the individual patient, fixation devices should be removed once their service as an aid to healing is accomplished. Austin Moore Hip Prosthesis removal should be followed by adequate post-operative management to avoid refracture.

Austin Moore Hip Prosthesis General Adverse Events

As with all major surgical procedures, risks, side effects and adverse events can occur. While many possible reactions may occur, some of the most common include: Problems resulting from anesthesia and patient positioning (e.g. nausea, vomiting, dental injuries, neurological impairments, etc.), thrombosis, embolism, infection, nerve and/or tooth root damage or injury of other critical structures including blood vessels, excessive bleeding, damage to soft tissues incl. swelling, abnormal scar formation, functional impairment of the musculoskeletal system, pain, discomfort or abnormal sensation due to the presence of the device, allergy or hypersensitivity reactions, side effects associated with hardware prominence, loosening, bending, or breakage of the device, mal-union, non-union or delayed union which may lead to breakage of the Austin Moore Hip Prosthesis, reoperation.
