Composition and morphology of wear debris in failed uncemented total hip replacement Interfacial membranes collected at revision from 11 failed uncemented Ti-alloy total hip replacements were examined. Particles in the membranes were characterised by electron microscopy, microchemical spectroscopy and particle size analysis. Most were polyethylene and had a mean size of 0.53 micron +/- 0.3. They were similar to the particles seen in the base resin used in the manufacture ... ...

Six-year results of hydroxyapatite-coated total hip replacement We present the 5.6- to 7.6-year results of our first 118 hydroxyapatite (HA)-coated total hip replacements in patients under 66 years of age. The titanium femoral component has proximal HA coating and was usually articulated with an HA-coated threaded cup. The HA coating of 50 microns thickness has a porosity of below 3%, 97% HA purity and 65% crystallinity. The survival rate at a mean of... ...

The Oxford medial unicompartmental knee replacement using a minimally-invasive approach This prospective study describes the complications and survival of the first 688 Phase 3 Oxford medial unicompartmental knee replacements implanted using a minimally-invasive technique by two surgeons and followed up independently. None was lost to follow-up. We had carried out 132 of the procedures more than five years ago. The clinical assessment of 101 of these which were available for... ...

Tibiofemoral movement 3: full flexion in the living knee studied by MRI We studied active flexion from 90° to 133° and passive flexion to 162° using MRI in 20 unloaded knees in Japanese subjects. Flexion over this arc is accompanied by backward movement of the medial femoral condyle of 4.0 mm and by backward movement laterally of 15 mm, i.e., by internal rotation of the tibia. At 162° the lateral femoral condyle lies posterior to the tibia.

Oxford medial unicompartmental knee arthroplasty We describe the outcome of a series of 124 Oxford meniscal-bearing unicompartmental arthroplasties carried out for osteoarthritis of the medial compartment. They had been undertaken more than ten years ago in a non-teaching hospital in Sweden by three surgeons. All the knees had an intact anterior cruciate ligament, a correctable varus deformity and full-thickness cartilage in the lateral... ...

The flexion gap in normal knees Varus and valgus joint laxity of the normal living knee in flexion was assessed using MRI. Twenty knees were flexed to 90° and were imaged in neutral and under a varus-valgus stress in an open MRI system. The configuration of the tibiofemoral joint gap was studied in slices which crossed the epicondyles of the femur. When a varus stress was applied, the lateral joint gap... ...

Micromotion of cemented and uncemented femoral components We evaluated the initial stability of cemented and uncemented femoral components within the femoral canals of cadaver femurs during simulated single limb stance and stair climbing. Both types were very stable in simulated single limb stance (maximum micromotion of 42 microns for cemented and 30 microns for uncemented components). However, in simulated stair climbing, the cemented componen... ...

Allograft versus autograft bone in scoliosis surgery The results of a study of the use of autograft versus allograft bone in the surgery of idiopathic adolescent scoliosis are presented. Two groups of patients, matched for age, sex, level and angle of curve, received bone grafts, 20 patients having autogenous bone from the iliac crest and the other 20 having donor bone from a bone bank. Both groups had otherwise identical posterior fusions ... ...

Chondrosarcoma of the bones of the hand Nineteen chondrosarcomas are reported arising in proximal phalanges or metacarpal bones of the hand mainly in elderly patients, predominantly women. The usual clinical presentation was of a progressively painful large tumour, often arising in a dormant lesion near the metacarpo-phalangeal joint. Radiologically most showed some bone expansion with a poorly defined area of destruction and a... ...

DEFORMITY CALCANEO-VALGUS Dịch bởi AI Một cuộc thảo luận về dị dạng thiết yếu ở bàn chân calcaneo-valgus phát triển một chủ đề ban đầu được đưa ra vào năm 1961 về tình trạng chân quặt lại tái phát (Evans 1961). Trong khi ở bàn chân bình thường, các cột giữa và bên đều có chiều dài gần bằng nhau, thì ở talipes equino-varus, cột bên dài hơn và ở calcaneo-valgus thì ngắn hơn cột giữa. Đề xuất là trong điều trị cả hai dị dạng, ch... ...
