follow – up was performed on the Birmingham Mid Head Resection (BMHR) .. good surgical technique and a well proven resurfacing implant is vital for success . The novel Birmingham Mid-Head Resection (BMHR) device offers the option. We have illustrated the surgical technique to manage this rare. Surgery was conducted via a standard posterior approach to the hip joint using a 58 mm BHR acetabular component, a 52 mm BMHR femoral head implant and.

The shape of the BMHR femoral stem is conical and is said to allow for improved physiologic loading similar to that of the intact femur. The BMHR prosthesis does not violate the femoral canal. Please review our privacy policy. If all these were to reach 7 years follow-up, the failure rate is predicted to be 2.

Find articles by Hassaan Q. The BMHR is specifically designed as an alternative surgery for young and active patients who would otherwise be forced to have a total hip replacement THR in the absence of a hip resurfacing. The valgus placement of the implant and radiographs suggest that reaming had thinned the medial calcar, potentially weakening the femur further.

Received Jan 11; Accepted May Open in a separate window. This is unlike the usual fracture pattern seen in conventional hip resurfacing arthroplasty and that seen in cadaveric BMHR studies.

This implant is a novel solution to addressing this challenging group of patients. The fracture techniquue is spiral in nature and reaches to the subtrochanteric area.

However, due to its existing positive results in our patients, the device is being developed as part of future resurfacing device designs. Twelve months later, he presented to casualty via ambulance with a clear history of a mechanical trip, right hip pain and inability to weight bear. He has addressed international conferences organized by the American, Canadian, British, European, Australian, Asia-Pacific and Japanese Orthopaedic Associations and several others as a distinguished guest lecturer.


This fracture pattern is different from published cadaveric studies, and clinicians using this implant should be aware of this as revision is likely to require a distally fitting, rather than a metaphyseal fitting stem. Mr McMinn specialises in conservative treatments for young and active patients.

However, resurfacing relies on the bone quality of the proximal femur. During the BMHR operation, the femoral head ball joint is resected through the middle, thereby removing the diseased or necrotic bone.

Anteroposterior radiograph of the right hip after revision surgery. Abstract Total hip arthroplasty in the young leads to difficult choices in implant selection. And, often confronted by the poor results of conventional hip replacement in young patients, he took up the challenge of developing an alternative treatment.

In addition to receiving honours of distinction from several quarters, the University of Birmingham has conferred on him the degree of Doctor of Medicine Honoris Causa in recognition of his sterling contributions to the medical profession.

Published online Aug Surgeons come from around the world to observe and train with Mr McMinn in Birmingham. Subsequent radiographs revealed an unusual periprosthetic fracture pattern around his right BMHR Fig. The BMHR is built on the clinical success of the BHR, offering all the advantages of a tedhnique resurfacing – a good range of movement, excellent stability, reduced risk of dislocation and better technjque options than a THR. Bose of ARCH is one of the very few surgeons in the world to perform this surgery.

This correlates with our case sudgical our patient also had a notched neck of femur. Risk of techmique femoral neck fracture after hip resurfacing arthroplasty: This device is a “Ceramic-on-Metal” CoM articulation. The BMHR is made up of three components – the femoral stem, a modular head and an acetabular cup. The fracture, however, has not spread in the usual transcervical or subcapital pattern. The patient, having previously had a left total hip replacement for osteoarthritis, subsequently underwent right hip BMHR for osteoarthritis Fig.


In addition he has developed other high performance hip and knee implants and instruments to provide a comprehensive range of solutions for the whole spectrum of joint disorders.

The femoral neck is prepared to receive the proximal load-bearing cone of the BMHR stem. J Bone Joint Surg Am. Hence, this report is important as it gives an insight as to what to expect with if tecnhique complication occurs and how it can be managed successfully.

This has never been described in the literature previously.

Shimmin AJ, Back D. Patient was on self medication with steroids. This is different to when conventional resurfacing is performed, when most of the femoral head is preserved and a resurfacing ‘cap’ is placed over the top. Gone are the days when young, active patients crippled from hip arthritis were told to shut up and put up with it.

A long stem, which was distally fitting, was used so as not to rely tecnique the fractured proximal metaphysis. He subsequently underwent revision surgery with a long uncemented stem.

The remaining femoral bone is then prepared into a conical shape and a matching stem is tapped into place without the need for cement or screws.

Olsen also describes two distinct fracture patterns:
