Hip Prosthesis Introduction, Specification, Uses & Sizes

Hip Prosthesis Introduction

Hip Prosthesis

A hip prosthesis, often known as a hip replacement, is a surgical treatment that involves the replacement of a broken or worn-out hip joint with an artificial joint known as a prosthesis. Individuals with severe hip joint disorders, such as arthritis, fractures, or other forms of hip joint degeneration, may benefit from this operation to decrease pain, increase mobility, and improve overall quality of life.

The hip joint is a ball-and-socket joint, with the “ball” being the femoral head (thigh bone) and the “socket” being the acetabulum, which is a component of the pelvis. Hip replacement surgery removes damaged cartilage and bone from the hip joint and replaces the damaged surfaces with prosthetic components consisting of metal and ceramic.

Hip Prosthesis Specification

Ageing, arthritis, fractures, and other degenerative disorders can cause intense pain and limited movement in the hip joint. These difficulties have a substantial influence on the quality of life of those who are impacted. Hip prosthesis offer a remedy by replacing injured or worn-out joint components and restoring function to an otherwise impaired joint.

Hip replacement surgery has become a frequent and effective treatment for those who have severe hip joint disorders, and it can considerably enhance the patient’s quality of life by lowering pain and boosting mobility.

Hip Prosthesis is design for patient with limited femoral neck above the lesser trochanter.
Prosthesis has a more vertical neck angle and is better indicated for the patient with a low or distal neck fracture.
Available in both Sterile and Non-Sterile packing.
Made up from high quality Medical grade stainless steel.

Hip Prosthesis Contraindications

Contraindications may be qualified or total, and need to be taken into consideration when evaluating the prognosis in each case. The physician’s education, training and professional judgement must be relied upon to choose the most appropriate device and treatment. Conditions presenting an increased risk of failure include:

Any active or suspected latent infection or marked local inflammation in or about the affected area.
Compromised vascularity that would inhibit adequate blood supply to the fracture or the operative site.
Bone stock compromised by disease, infection or prior implantation that can not provide adequate support and/or fixation of the devices.
Material sensitivity, documented or suspected.
Obesity. An overweight or obese patient can produce loads on the implant that can lead to failure of the fixation of the device or to
failure of the device itself.
Patients having inadequate tissue coverage over the operative site.
Implant utilization that would interfere with anatomical structures or physiological performance.
Any mental or neuromuscular disorder which would create an unacceptable risk of fixation failure or complications in postoperative care.
Other medical or surgical conditions which would preclude the potential benefit of surgery.
All associated diseases which could endanger the function and success of the Hip Prosthesis.

Warnings and Precautionary for Hip Prosthesis

Before using 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.

Prosthesis is made from medical grade materials and are designed, constructed and produced with utmost care. These quality Prosthesis 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 Hip Prosthesis 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 Prosthesis.

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 Hip Prosthesis, 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 Prosthesis.
Mechanical failure of the implant, including bending, loosening or breakage.
Migration of implant resulting in injury.

Preoperative Planning for 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 set of Prosthesis must be available.

The clinician should discuss with the patient the possible risks and complications associated with the use of Prosthesis. 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.

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 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.

Hip Prosthesis Warnings

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. Implant removal should be followed by adequate post-operative management to avoid refracture.

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 implant, reoperation.
