Does Focused Gluteus Medius Muscle Stretching After Total Hip Arthroplasty Work? An Electromyographic Study.

Background: The hypothesis of this randomized prospective study was that focused stretching of the gluteus medius muscle, in addition to generalized physical therapy, is likely to improve muscle reaction time and positively impact the return to function of the patient after primary total hip arthroplasty.

Methods: We prospectively recruited 28 patients undergoing primary total hip arthroplasty from January 2021 to January 2023. The control group (13 patients) received a conventional rehabilitation protocol, while the intervention group (15 patients) received focused stretching exercises of the gluteus medius muscle in addition to the conventional rehabilitation protocol.

Onlay fibula autografting technique and its comparison with cortical allograft for the reconstruction of periprosthetic bone defects around the femur.

Background: Bone defect around the femur related to revisions or periprosthetic fractures (PFF) is an issue. We present a bone defect reconstruction technique in femoral revisions and/or PFF using fibula autograft and compared our radiological and clinical results to that of allograft.

Methods: A total of 53 patients who underwent revision hip arthroplasty and/or PFF fixation with the use of cortical fibula autograft (FG group) or cortical allograft (CG group) were evaluated.

Dual-mobility bearings for patients with abductor-trochanteric complex insufficiency.

Introduction: The purpose of this study was to summarise the performance of dual-mobility cup systems for revision total hip arthroplasty in patients with abductor-trochanteric complex deficiency.

Methods: We prospectively followed 17 patients (20 hips) with a mean age of 64.5 years (range 33-89 years) who underwent acetabular reconstruction with dual-mobility cups for aseptic loosening in 12 hips, infection treatment as second or single stage in 6 hips, and instability in 2 hips.

Tapered stems one-third proximally coated have higher complication rates than cylindrical two-third coated stems in patients with high hip dislocation undergoing total hip arthroplasty with step-cut shortening osteotomy.

Background: The results of cementless stems in total hip arthroplasty (THA) done because of congenital dislocation with step-cut osteotomy is not well known, particularly the influence of the design and the role of extent of porous coating. Therefore we performed a retrospective study to evaluate the mid to long-term results THA performed with a single type acetabular component and different geometry and fixation type stems with ceramic bearings in the setting of step-cut subtrochanteric osteotomy in high hip dislocated (HHD) patients. We asked if the stem type affect the outcomes in terms of (1) intra and postoperative complication rates (2) radiographic outcomes (3) prosthesis survival in step-cut subtrochanteric shortening osteotomy.

Effects of NSAIDs and hydroxyapatite coating on osseointegration.

Purpose: The aim of our study is to investigate the bone ongrowth of two different alternative surfaces and the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) on osseointegration.

Methods: Hips of 40 New Zealand white rabbits were operated bilaterally. Hydroxyapatite (HA)-coated titanium rods were implanted into the right femur, and grit-blasted titanium rods were implanted into the left femur.

[Venous thromboembolism prophylaxis in major orthopaedic surgery: A multicenter, prospective, observational study].

Objectives: We investigated risk factors for venous thromboembolism (VTE), prophylaxis measures employed, and incidence of symptomatic deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients undergoing major orthopaedic surgery (MOS).

Methods: An open, multicenter, prospective, observational study was conducted in 21 medical centers, comprising 899 patients. Of these, 316 patients (35.

[Total hip arthroplasty in the treatment of developmental dysplasia of the hip].

Total hip arthroplasty (THA) is the preferred treatment for patients with severe arthritis of the hip secondary to developmental hip dislocation or dysplasia. However, THA may be difficult due to bone and soft tissue problems that arise from hip dislocation or dysplasia. Another problem is that patients are usually young, which may affect the long-term survival of the prosthesis.

Extravascular compression of the femoral vein due to wear debris-induced iliopsoas bursitis: a rare cause of leg swelling after total hip arthroplasty.

We present a patient with unilateral, spontaneous, late leg swelling that developed 4 years after total hip arthroplasty. The etiology was the compression of the internal iliac vein by a voluminous iliopsoas bursitis caused by polyethylene debris. The expansive lesion was detected by ultrasound, arthrography, and magnetic resonance imaging.

Posterior bone block for footdrop: a report of two cases.

A posterior bone-block operation is one of the few treatment options in cases of paralytic footdrop. A case with a flail ankle and no bony deformity is ideal for this approach. Two cases of acquired flail ankle with equinus deformity were treated using a new modification of the bone-block technique that does not interfere with subtalar joint motion.
