Long-term outcomes with a partial neck-preserving cementless short stem in primary total hip arthroplasty for young patients: a single center first one hundred cases.

Purpose: This study aimed to assess the long-term results of THA patients who received a cementless short stem regarding clinical outcomes, bone changes, complications, and incidence of femoral revision.

Methods: A retrospective evaluation of the first 100 THA employing a type 2B cementless stem (Mini hip stem, Corin, Cirencester, United Kingdom) by the same surgeon at one institution. We only include patients with 18 years or more, and with a minimum follow up of 8 years.

Successful hip revision surgery following refracture of a modern femoral stem using a cortical window osteotomy technique: A case report and review of literature.

Background: The ExeterTM Universal cemented femoral component is widely used for total hip replacement surgery. Although there have been few reports of femoral component fracture, removal of a broken femoral stem can be a challenging procedure.

Case Summary: A 54-year-old man with a Dorr A femur sustained a refracture of a primary ExeterTM stem, two years after receiving a revision using a cement-within-cement technique (CWC) through an extended trochanteric osteotomy (ETO).

Late Periprosthetic Femoral Stress Fracture Associated with Extra-articular Deformity in a Patient with Fibrous Dysplasia: A Case Report.

Case: In the setting of a total hip arthroplasty performed in a patient with a proximal femoral deformity, atraumatic periprosthetic femoral stress fracture may arise as a complication. We report a rare case of a late periprosthetic femoral stress fracture around a cemented stem in a patient with a history of fibrous dysplasia of the proximal femur. After a 10-year uneventful period, the patient complained about a subtle, subacute pain in his left thigh induced by exercise but not with daily axial load.

Assessment of Medical and Social Risk Factors Before Arthroplasty in Argentina: A Poll of Argentinian Hip and Knee Association (ACARO) Members.

Background: Assessment of risk factors is crucial for lowering complication rates and costs of hip and knee arthroplasty. The objective of this study was to assess if members of the Argentinian Hip and Knee Association (ACARO) are influenced by such risk factors when planning surgery.

Methods: In 2022, a survey was distributed as an electronically based questionnaire to 370 members of the ACARO.

Medium-term outcomes of conventional versus short uncemented femoral stems for primary total hip arthroplasty in patients younger than 55 years.

Background: Short stems are designed with a bone preservation philosophy in mind. This study aims to compare the outcomes/complications and survival of a collarless fully hydroxyapatite (HA)-coated conventional tapered stem and a HA-coated partial neck-retaining uncemented short stem in patients ⩽55 years old at medium-term follow-up.

Methods: We retrospectively studied 247 uncemented THAs operated between 2010 and 2014, comparing 146 patients treated with the fully HA-coated collarless stem (Group A) with 101 patients treated with a partial neck preserving, HA-coated short stem (Group B).
