In the modern era of hip arthroplasty, surgical techniques have evolved to prioritise both functional and aesthetic outcomes. One such innovation is the Bikini Incision Direct Anterior Approach (DAA) for hip replacements, which promises a blend of reduced invasiveness, quicker recovery, and superior aesthetic results. This article delves into the specifics of the Bikini Incision DAA, highlighting its advantages.

The Bikini Incision DAA Technique:

The Bikini Incision DAA employs a front-facing, or anterior, approach to access the hip joint, making a precise incision along the bikini line, which is parallel to the skin creases. This is a departure from traditional longitudinal incisions and is designed to cause less disruption to the surrounding musculature, blood vessels, and nerves.

In the ever-evolving realm of orthopaedic surgery, innovation is the cornerstone that propels the field into new dimensions of patient care and surgical excellence. Among the vanguards of this transformative movement is Prof. Paul Lee, an esteemed Orthopaedic Surgeon and Sports Medicine expert based in 108 Harley Street and Weymouth Street Hospital, London. With a robust academic and clinical portfolio, Prof. Lee is not just on the frontline of orthopaedic surgical practice, but also on the cutting edge of using novel surgical techniques. One of such remarkable contributions is the SPAIRE (Spare Piriformis And Internus, Repair Externus) Hip Replacement technique, a novel method meticulously designed to ameliorate the drawbacks commonly associated with traditional hip replacement surgeries.

Using the United Orthopaedic Conformity stem and UDM cup, Prof. Lee is a champion of performing total hip arthroplasty (THA) using the SPAIRE technique.

The SPAIRE Technique: A Glimpse into the Future

The SPAIRE Hip Replacement technique stands out with its muscle-sparing mini-posterior approach to the hip. This unique approach is tailored to cause minimal damage to the surrounding tendons and muscles, significantly enhancing the post-operative recovery process. Unlike traditional hip replacements which may involve cutting through crucial posterior tendons, the SPAIRE technique only necessitates the division and subsequent repair of the obturator externus tendon, leaving other key tendons and muscles intact. This meticulous approach aids in significantly reducing post-operative pain and accelerating the rehabilitation process, marking a substantial stride towards improving patient outcomes.

The SPAIRE Hip Replacement technique is a novel method that has been developed to mitigate the drawbacks associated with traditional hip replacement surgeries. Below are the intricate details of the SPAIRE Hip Replacement technique:

1. Surgical Approach:

• The SPAIRE technique employs a muscle-sparing mini-posterior approach to the hip, which is designed to cause minimal damage to the surrounding tendons and muscles, significantly enhancing the post-operative recovery process.

2. Tendon Management:

• Unlike traditional hip replacements which approach through the posterior tendons known to be of great importance when rising from a seated position or during walking or climbing stairs, the SPAIRE technique only involves the division and subsequent repair of the obturator externus tendon, leaving other key tendons and muscles intact.

3. Functional Outcomes:

• The SPAIRE technique has been shown to have no disadvantage in terms of functional outcomes when compared to traditional methods. Patients undergoing this procedure are encouraged to exercise the hip through a full range of motion immediately post-surgery, as the on-table stability provided by the SPAIRE technique is impressive. This technique enhances the level of function and mobility in patients, according to ongoing randomised prospective studies.

4. Preservation of Muscles and Tendons:

• The preservation of the “short external rotator” muscle group, which serves primarily as an abductor and extensor of the flexed hip, is a hallmark of the SPAIRE technique. This preservation has a profound influence on weight-bearing, rising, and propulsive motions, significantly enhancing the patient’s mobility post-surgery.

5. Reduced Tendon Damage:

• Fewer tendons are damaged using the SPAIRE technique compared to any other approach to the hip, including Direct Anterior and Direct Superior approaches. This is primarily due to the muscle-sparing posterior approach that the SPAIRE technique employs.

6. Post-operative Restrictions:
• One of the significant advantages of the SPAIRE technique is the absence of post-operative restrictions on the patient, who is immediately encouraged to exercise the hip through a full range of motion. This lack of restriction speeds up the rehabilitation process and returns the patient to normal functionality quicker.

7. Prospective Studies and Adoption:
• The SPAIRE technique is undergoing randomised prospective studies to evaluate its benefits using objective measurements of gait and muscle power as well as functional and patient-reported outcomes. It is believed that this technique may become the default technique for hemi- and total- hip arthroplasty through a posterior approach and for all hip fracture arthroplasty cases.

8. Professional Adoption:
• Some surgeons have already adopted the SPAIRE technique for all routine hip arthroplasties and are comparing the outcomes with traditional methods to gather comprehensive data on its advantages.

9. SPAIRE Hip Instruments:
• SPAIRE Hip Instruments are exclusively crafted to accommodate the unique approach of the SPAIRE technique, emphasising the specialised nature of this procedure.

The SPAIRE Hip Replacement technique is a significant stride toward minimising the adverse effects associated with traditional hip replacement surgeries. Its muscle-sparing approach, minimal tendon damage, and enhanced post-operative functionality make it a promising alternative in the realm of orthopaedic surgery.

Setting the Pace in Orthopaedic Excellence

As Prof. Lee continues to trailblaze the path of orthopaedic innovation with the SPAIRE Hip Replacement technique, he embodies the epitome of medical excellence and patient-centric care. His notable contributions are not only a boon to the medical community but a beacon of hope for individuals seeking a life free from the shackles of hip joint ailments. Prof. Lee’s work resonates with the ethos of advancing surgical techniques to foster better patient outcomes, underscoring the profound impact of the SPAIRE technique in the sphere of hip arthroplasty.

In a world where medical advancements transmute the impossible into possible, Prof. Lee, with his SPAIRE Hip Replacement technique, stands as a colossal figure leading the charge towards a future where hip replacement surgeries are synonymous with rapid recovery, minimal pain, and enhanced mobility.

The United Orthopedic UK team frequently assist orthopaedic surgeons within surgery with a variety of our hip and knee implants. One of the surgeons that we work closely with is @Dr. Karuppiah Mahalingam, a Consultant Orthopedic Surgeon based at the @Mater Private Network hospital in Cork, Ireland.

Using the United Orthopedic Conformity stem and U-Motion II, Dr. Mahalingam is a champion of performing total hip arthroplasty (THA) using the bikini incision direct anterior approach (DAA) surgical technique.

After undergoing Bikini DAA, many patients leave hospital just one day after surgery and return to better quality of life at a quicker rate compared to standard hip replacement surgery.

What is Bikini Incision Direct Anterior Approach (DAA)?

The primary goal of minimal access hip replacement is to preserve muscles, blood vessels, and nerves surrounding the joint with minimal harm. The Bikini DAA approach is a new type of minimally invasive anterior approach in total hip replacement. It significantly reduces the potential risks associated with surgery such as blood loss. In addition, this type of procedure compared to conventional hip replacements speeds up post-operative recovery and rehabilitation times.

What are the benefits of the Bikini DAA?

1. Decreased recovery time and rehabilitation time

Compared to standard hip replacement surgery, the Bikini DAA surgical technique dramatically reduces the post-operative recovery time as no muscles are cut during the procedure. Typically, patients can stand up and practice walking with crutches almost immediately after surgery and can return to driving within one month of surgery. As a large part of recovery is due to the healing of internal soft tissues and surgical wounds, this minimally invasive technique greatly reduces the amount of time it takes to rehabilitate after surgery.

2. Shorter hospital stay

In many cases, patient’s length of stay at the hospital is dramatically reduced. As many patients can start walking with crutches soon after the procedure, patients are allowed to return home much sooner, generally the day after surgery. Although post-operative check-ups will be required, patients often find their recovery more pleasant and enjoyable in the comfort of their own home.

3. Small skin scar

Many patients will cosmetically benefit from a much smaller scar after their hip surgery. The incision is much shorter and smaller reducing the amount of scar tissue post-surgery. Because the wound is largely hidden in females by a bikini, it is also often referred to as a bikini incision hip replacement.

4. Faster return to daily activities

Patients who undergo minimally invasive hip replacement surgery recover much quicker than patients undergoing conventional hip replacement surgery, enabling them to return to their daily activities much quicker.

5. Less blood loss

As a minimal access hip replacement technique, it preserves both muscles and vessels meaning blood loss is significantly reduced. With blood transfusions seldomly needed, the risk of blood clots in the patient’s legs is also significantly reduced.

6. Reduced risk of dislocation

Dislocation is mainly related to posterior hip structure damage. However, as Bikini DAA is performed from the front of the body this technique significantly reduces the likelihood of hip dislocation. Also due to the preservation of muscles that work to improve the stability of the hip, movement post-surgery is not as limited in comparison to standard hip replacement.

7. Prevention of limping

Characterised by the surgical procedure that preserves muscles, blood vessels, and nerves during the exposure of the hip joint, minimal access hip replacement significantly reduces the chances of post-operative limping. With excellent control of their legs and no requirement for pain management medication as part of their rehabilitation, patients are able to drive very soon after surgery.
