Midterm Results of Primary Exeter Cemented Stem in a Select Patient Population.

J Bone Joint Surg Am 2021 May 11. Epub 2021 May 11.

Department of Orthopedic Surgery, Mayo Clinic, Rochester, Minnesota.

Background: Most North American surgeons predominantly use uncemented stems in primary total hip arthroplasties (THAs) and reserve cemented stems for selected older patients and those with poor bone quality. However, data on this "selective use" strategy for cemented stems in the population at risk for periprosthetic fracture and implant loosening are limited. The purpose of this study was to describe implant survivorship, complications, and radiographic results of a specific collarless, polished, tapered cemented stem (Exeter; Stryker) used selectively in a predominantly elderly population undergoing primary THA.

Klinik für Orthopädie, Unfallchirurgie und Sporttraumatologie, Marienhaus Klinikum Hetzelstift, Stiftstraße 10, 67435, Neustadt an der Weinstraße, Deutschland.

Joint dislocations are always accompanied by rupture of the joint capsule. Depending on the forces exerted on the joint as well as individual bone quality, fractures (dislocation fractures) and injuries to ligaments occur. As blood vessels and nerves can also be damaged, reduction is an urgent measure. Read More

Morphological variants to predict outcome of avascular necrosis in developmental dysplasia of the hip.

Bone Joint J 2021 May;103-B(5):999-1004

Department of Orthopaedic Surgery, Sophia's Children's Hospital, Erasmus University Medical Centre, Rotterdam, The Netherlands.

Aims: The most important complication of treatment of developmental dysplasia of the hip (DDH) is avascular necrosis (AVN) of the femoral head, which can result in proximal femoral growth disturbances leading to pain, dysfunction, and eventually to early onset osteoarthritis. In this study, we aimed to identify morphological variants in hip joint development that are predictive of a poor outcome.

Methods: We retrospectively reviewed all patients who developed AVN after DDH treatment, either by closed and/or open reduction, at a single institution between 1984 and 2007 with a minimal follow-up of eight years. Read More

Comparison between freehand technique and computed tomography-based navigation in acetabular cup placement through direct anterior approach for total hip arthroplasty.

Arch Orthop Trauma Surg 2021 Apr 30. Epub 2021 Apr 30.

Department of Orthopaedic Surgery, Daini Osaka Police Hospital, 2-6-40 Karasugatsuji, Tennouji-ku, Osaka, 543-8922, Japan.

Introduction: In total hip arthroplasty (THA), improper cup orientation can result in dislocation, early excessive polyethylene wear, and pain following THA. The supine position during THA provides a more reproducible functional pelvic position than the lateral decubitus position and may allow freehand cup placement as reliable as that obtained by computer navigation. The purpose of this study was to investigate the accuracy of freehand cup placement through a supine direct anterior approach (DAA) compared with computed tomography (CT)-based navigation. Read More

Effect of intraoperative treatment options on hip joint stability following total hip arthroplasty.

J Orthop Res 2021 Apr 29. Epub 2021 Apr 29.

Center for Orthopaedic Biomechanics, University of Denver, Denver, Colorado, USA.

Dislocation remains the leading indication for revision of total hip arthroplasty (THA). The objective of this study was to use a computational model to compare the overall resistance to both anterior and posterior dislocation for the available THA constructs commonly considered by surgeons attempting to produce a stable joint. Patient-specific musculoskeletal models of THA patients performing activities consistent with anterior and posterior dislocation were developed to calculate joint contact forces and joint positions used for simulations of dislocation in a finite element model of the implanted hip that included an experimentally calibrated hip capsule representation.

Clinical application of femoral derotation osteotomy combined with medial patellofemoral ligament reconstruction for patellar dislocation with excessive femoral internal torsion.

Asian J Surg 2021 Apr 23. Epub 2021 Apr 23.

Department of Orthopaedic Surgery the Affiliated Hospital of Southwest Medical University Luzhou, China. Electronic address:

Recurrent patellar dislocation (RPD) is multifactorial disease, and excessive femoral internal torsion has been considered as an important risk factor for recurrence of patellar dislocation and graft failure after surgery 1 . Satisfactory clinical outcomes depend on correcting of the pathologic abnormalities around the patellofemoral joint and torsional deformity of the lower extremity. At present, conventional isolated medial patellofemoral ligament (MPFL) reconstruction without addressing excessive femoral internal torsion may lead to MPFL graft failure 2,3 , because increased femoral internal torsion can significantly increase a persistently lateralizing force on the patella 4 .

Malays Orthop J 2021 Mar;15(1):128-131

Department of Orthopaedics, Max Super Speciality Hospital Patparganj, Delhi, India.

Salvage total hip arthroplasty (THA) may be required to manage femoral neck fracture implant failures, avascular necrosis and secondary hip arthritis. Cannulated cancellous screws can become stripped or incarcerated during the initial implantation and pose hardware removal issues. We present a novel technique for safe screw removal in a 62-year-old female patient with a painful right hip. Read More
