Purpose: Adhesive capsulitis of the hip (ACH) is likely that this condition had been previously encountered, but easily unrecognised. We investigated the clinical features of patients with ACH, the efficacy of ultrasound-guided intra-articular hydrodilatation, and the patients' prognosis.

Methods: We enrolled 84 patients (93 hips) who visited the outpatient clinic from August 2018 to November 2019.

Incidence of nonunion after surgery of distal femoral fractures using contemporary fixation device: a meta-analysis.

Purpose: Nonunion is the most frequent cause of reoperation and is associated with high morbidity after distal femur fracture (DFF). We examined the rates of nonunion requiring reoperation after fixation for DFF using a locking compression plate (LCP) or retrograde intramedullary nail (RIMN).

Methods: We included four studies comparing LCP and RIMN and 38 single-cohort studies reporting LCP or RIMN.

Incidence and risk factors of knee injuries associated with ipsilateral femoral shaft fractures: A multicentre retrospective analysis of 429 femoral shaft injuries.

A femoral shaft fracture is usually a high-energy injury and, thus, is likely to be accompanied by an injury of adjacent joints such as a knee ligament injury. However, these associated injuries are often neglected because of severe pain and deformity. The purpose of the current study is to evaluate the incidence, type and risk factors of ipsilateral knee injuries associated with femoral shaft fractures.

Effectiveness of controlled telescoping system for lateral hip pain caused by sliding of blade following intramedullary nailing of trochanteric fracture.

Introduction: The purpose of this study was to demonstrate the effectiveness of controlled telescoping system for lateral hip pain caused by sliding of the blade following intramedullary nailing of trochanteric fractures.

Materials And Methods: A retrospective cohort study was performed to compare the controlled telescoping system (Compression Hip Nail; CHN) with the conventional sliding system (Proximal Femoral Nail Antirotation; PFNA) for trochanteric fractures. 74 cases in the PFNA group and 77 cases in the CHN group were included from two university hospitals in this study.

Surgical outcomes of intramedullary nailing for diaphyseal atypical femur fractures: is it safe to modify a nail entry in bowed femur?

Introduction: The purpose of the study was to determine the surgical outcomes of intramedullary nailing in diaphyseal atypical femoral fractures (AFFs) and to evaluate the clinical outcomes of nail entry modification technique.

Materials And Methods: We retrospectively reviewed diaphyseal AFFs treated with IMN at nine institutions. In total, 82 patients were included.

Factors affecting fracture location in atypical femoral fractures: A cross-sectional study with 147 patients.

Introduction: Many studies have tried to determine the characteristics of atypical femoral fractures (AFFs) through age-, sex-, and ethnicity-matched comparison with non-AFFs. However, we hypothesized that diaphyseal AFFs would have characteristics different from those of subtrochanteric AFFs. The aim of this study was to evaluate the clinical features of diaphyseal/subtrochanteric AFFs and determine the factors related to fracture location.

Stoppa Approach for Anterior Plate Fixation in Unstable Pelvic Ring Injury.

Background: The Stoppa (intrapelvic) approach has been introduced for the treatment of pelvic-acetabular fractures; it allows easy exposure of the pelvic brim, where the bone quality is optimal for screw fixation. The purpose of our study was to investigate the surgical outcomes of unstable pelvic ring injuries treated using the Stoppa approach for stable anterior ring fixation.

Methods: We analyzed 22 cases of unstable pelvic ring injury treated with plate fixation of the anterior ring with the Stoppa approach.

Challenge to treat hypertrophic nonunion of the femoral shaft: the Poller screw augmentation technique.

The management of a femoral nonunion after intramedullary nailing is challenging. Exchange nailing or plate augmentation has been used to treat hypertrophic nonunions previously. The Poller screw augmentation technique is a simple procedure that can be performed in the outpatient surgery.

Measurement of Optimal Insertion Angle for Iliosacral Screw Fixation Using Three-Dimensional Computed Tomography Scans.

Background: Percutaneous iliosacral screw fixation can provide stable fixation with a minimally invasive surgical technique for unstable posterior pelvic ring injuries. This surgical technique is not limited by cases of difficult fracture patterns, sacral dysplasia, and small sacral pedicles that can occur in Asians. The purpose of this study was to investigate the incidence of the sacral dysplasia in the Korean population and determine the optimal direction of iliosacral screws by analyzing pelvic three-dimensional computed tomography (3D-CT) scans.

Incidence of Avascular Necrosis of the Femoral Head After Intramedullary Nailing of Femoral Shaft Fractures: A Multicenter Retrospective Analysis of 542 Cases.

The goal of this study was to determine the incidence of avascular necrosis of the femoral head (AVNFH) after intramedullary nailing of femoral shaft fractures and to identify risk factors for developing AVNFH.We retrospectively reviewed all patients with femoral shaft fractures treated with antegrade intramedullary nailing at 10 institutions. Among the 703 patients enrolled, 161 patients were excluded leaving 542 patients in the study.

Background: We present the surgical technique of separate vertical wiring for displaced inferior pole fractures of the patella combined with Krachow suture and report the surgical outcomes.

Materials And Methods: Between September 2007 to May 2012, 11 consecutive patients (mean age, 54.6 years) with inferior pole fractures of the patella (AO/OTA 34-A1) were retrospectively enrolled in this study.

Conservative treatment after failure of internal fixation for periprosthetic femoral fractures: a report of two cases.

Osteosynthesis using compression or locking plate following indirect fracture reduction and using a minimally invasive technique has been recommended for the surgical treatment of Vancouver B1 and C periprosthetic femoral fractures. Recent advancements in fracture healing emphasize the significance of the type of mechanical stability depending on fracture patterns and the importance of the preservation of the blood supply around the fracture sites. We report two cases of mechanical failure after internal fixation of periprosthetic femoral fractures despite adherence to the principles of fracture care.

Radiological assessment of the safe zone for medial minimally invasive plate osteosynthesis in the distal femur with computed tomography angiography.

Introduction: Surgical treatment options for distal femur fractures include intramedullary nailing or plating using a lateral or lateral parapatellar approach. However, medial plating is required for additional stability in some fractures such as severely comminuted fractures and periprosthetic fractures, and in those for which use of a lateral plate or nail is not appropriate. This study aimed to explore the safe zone for medial minimally invasive plate osteosynthesis of the distal femur with computed tomography angiography.

Indolent infection in nonunion of the distal femur.

In the treatment of nonunions of the distal femur, infection should be excluded. However, it is difficult to determine whether the nonunion is infected or not with negative history and signs of infection. The purpose of this study was to investigate indolent infection as a cause of presumptive aseptic distal femur nonunion.

Factors contributing to inherent varus alignment of lower limb in normal Asian adults: role of tibial plateau inclination.

Purpose: This prospective study aimed to evaluate radiographically, mechanical or hip-knee-ankle (HKA) axis in healthy, asymptomatic, Asian (Indian and Korean) adults between 20 and 40 years of age to determine the incidence of inherent varus (mechanical limb alignment of >3° varus) and the factors influencing it.

Methods: Three hundred and eighty-eight lower limbs were evaluated using full length, standing hip-to-ankle radiographs in 198 healthy, asymptomatic, Asian (Indian and Korean) adults between 20 and 40 years of age to assess the hip-knee-ankle (HKA) angle, medial proximal tibial angle (MPTA), femoral bowing and femoral neck-shaft angle to determine the incidence of inherent varus (mechanical limb alignment of >3° varus) and the factors influencing it.

Results: Overall, the mean HKA angle was 177.

Operative treatment of communited olecranon fractures using tension-band wiring and miniplate augmentation.

Olecranon fractures are intra-articular injuries that require anatomic restoration of the articular surface. For most simple noncomminuted transverse olecranon fractures, tension band wire fixation can provide a stable construct to allow for early joint range of motion. However, in comminuted olecranon fractures, it is difficult to provide a sufficient buttress for impacted articular fragments using tension band wire fixation.

Minimally invasive plate osteosynthesis for metastatic pathologic humeral fractures.

Because patients with metastatic bone disease may survive only 3 to 12 months, the goal of surgery for pathologic fractures is to attain rigid and durable internal fixation and immediate postoperative use of the upper extremity. Surgical options such as intramedullary nailing, plating, and insertion of prosthesis usually reinforced with bone cement have been proposed for pathological humeral fractures. We describe a 42-year-old man with a pathologic distal humeral fracture.

Seven-year results of a tapered, titanium, hydroxyapatite-coated cementless femoral stem in primary total hip arthroplasty.

Background: Aseptic loosening of cemented hip prostheses is recognized as a long-term problem, and especially in males and younger patients. Much energy has been focused on developing new prostheses that are designed for cementless fixation. We evaluated the performance of and periprosthetic bone response to a tapered, titanium, hydroxyapatite (HA)-coated femoral hip prosthesis at a minimum of 7 years of follow-up after treatment with primary total hip arthroplasty.
