The Tibia Plafond Horizontal Orientation Angle for Frontal Alignment Evaluation of the Distal Lower Extremity.

PURPOSE OF THE STUDY Osteotomies around the knee are an established technique for treating knee osteoarthritis and other knee conditions by redistributing the body's weight and force within and around the knee joint. The aim of this study was to determine if the Tibia Plafond Horizontal Orientation Angle (TPHA) is a reliable measure for describing ankle alignment of the distal tibia in the coronal plane. MATERIALS AND METHODS This retrospective study included patients who underwent supracondylar rotational osteotomies for correction of femoral torsion.

In closed wedge distal femur osteotomies for correction of valgus malalignment overcorrection of mLDFA should be avoided.

Purpose: The purpose of the study was to investigate the influence of the mLDFA (mechanical lateral distal femur angle) as a parameter in varus realignment osteotomies for valgus deformities of the knee. We hypothesized that joint line obliquity with mLDFA > 90° after distal femur osteotomy (DFO) is associated with inferior clinical outcome.

Methods: In a retrospective study, a total of 52 patients with isolated femoral valgus deformities were included in the study.

Besides the scientific evidence, all group members rated the statements to identify possible gaps between literature and current clinical practice.

Ankle fractures of the geriatric patient: a narrative review.

The present narrative review provides a summary of current concepts for the treatment of ankle fractures in elderly patients. Despite a high complication rate, open reduction and internal fixation is the gold standard for operative care. However, individual patient-based treatment decision considering the soft-tissue status, the fracture pattern, as well as the patient's mobility and comorbidities is mandatory to achieve sufficient patient outcomes.

Risk of Periprosthetic Joint Infection after Posttraumatic Hip Arthroplasty following Acetabular Fractures.

Background: Raised complication rates have been reported for total hip arthroplasty (THA) in posttraumatic hip joints after acetabular fractures with prior open reduction and internal fixation (ORIF). The present study evaluated (I) postoperative surgical site infection and the risk of early infection following THA in posttraumatic hip joints after acetabular fractures and (II) the discriminatory ability of preoperative C-reactive protein (CRP) blood levels for periprosthetic joint infection (PJI).

Materials And Methods: Patients were included who had undergone THA (2014-2019) after prior ORIF, and nonsurgically treated acetabular fractures.

Os acromiale: prevalence and associated patient-related factors-a population-based study of three thousand and fifty participants.

Purpose: The presence of os acromiale is of clinical relevance before performing shoulder surgery but ethnic differences and little information regarding associated factors seem to be present. Population-based studies to clarify these topics are essential so the purpose of this study was to assess the prevalence, anatomy, and associations of os acromiale in a general adult population.

Methods: Both shoulders of 3050 participants from the population-based Study of Health in Pomerania (SHIP) were assessed on magnetic resonance imaging (MRI).

[MRI case series shows the development of medial gonarthrosis after medial meniscus tear and partial medial meniscectomy].

Meniscal injuries lead to changes in pressure distribution in the knee joint. The risk of developing gonarthrosis increases by the amount of resected meniscal tissue. Based on 4 MRI examinations conducted over an 8‑year time period, the present case report shows the progress of cartilage degeneration after a traumatic medial meniscus lesion and subsequent partial meniscus resection in a 46-year-old male patient.

Weight-bearing Restrictions after Distal Femur Fractures - Review of Current Literature.

The incidence of distal femur fractures increases in the geriatric patient. The primary treatment goal in these fractures is early mobilisation to prevent secondary injuries associated with immobility. In light of the increasing spectrum of therapeutic options for postoperative fracture treatment, including double plating, nail-plate combination and distal femur replacement as postoperative treatments, weight-bearing recommendations are becoming increasingly important.

Methods: Twenty-four patients (28 varus knees; mechanical tibiofemoral angle: -11.

Influence of axial limb rotation on radiographic lower limb alignment: a systematic review.

Introduction: The influence of limb malrotation on long-leg radiographs (LLR) is frequently discussed in literature. This systematic review aimed to describe the influence of limb rotation on alignment measurements alone and in combination with knee flexion, and determine its clinical impact.

Materials And Methods: A literature search was conducted in June 2021 using the databases MEDLINE, Cochrane, Web of Science (Clarivate Analytics), and Embase.

Single-stage total hip arthroplasty after failed fixation of proximal femoral fractures: an increased risk for periprosthetic joint infections?

Background: Higher complication rates have been reported for total hip arthroplasty (THA) after osteosynthesis of proximal femur fractures (PFF). This study evaluated the infection risk for conversion of internal fixation of PFF to THA by a single-staged procedure in the absence of clear infection signs.

Methods: Patients undergoing a one-staged conversion to THA (2013-2018) after prior internal fixation of the proximal femur were included.

Increased tibial tubercle-trochlear groove and patellar height indicate a higher risk of recurrent patellar dislocation following medial reefing.

Purpose: Identifying anatomical risk factors on recurrent dislocation after medial reefing is important for deciding surgical treatment. The present study aimed to retrospectively analyze the preoperative magnetic resonance imaging (MRI)-based parameters of patients treated with medial reefing and whether these parameters lead to a higher risk of recurrent dislocation.

Methods: Fifty-five patients (18.

The ischiofemoral space of the hip is influenced by the frontal knee alignment.

Purpose: The ischiofemoral distance (IFD), defined as the distance between the ischial tuberosity and the lesser trochanter of the femur, is gaining recognition as an extra-articular cause of hip pain. It is unknown whether the IFD is influenced by the frontal knee alignment. The aim of this study was to determine the influence of realignment surgery around the knee on the IFD.

3D computational anatomy of the scaphoid and its waist for use in fracture treatment.

Background: A detailed understanding of scaphoid anatomy helps anatomic fracture reduction, and optimal screw position. Therefore, we analysed (1) the size and shape variations of the cartilage and osseous surface, (2) the distribution of volumetric bone mineral density (vBMD) and (3) if the vBMD values differ between a peripheral and a central screw pathway?

Methods: Forty-three fresh frozen hand specimens (17 females, 26 males) were analysed with high-resolution peripheral quantitative computed tomography (HR-pQCT) and dissected to compute a 3D-statistical osseous and cartilage surface model and a 3D-averaged vBMD model of the scaphoid. 3D patterns were analysed using principal component analysis (PCA).

Radiographic parameter(s) influencing functional outcomes following angular stable plate fixation of proximal humeral fractures.

Purpose: Radiographic parameters which correlate with poor clinical outcome after proximal humeral fractures could be helpful indicators to answer the question which patients should be followed up closer. Moreover, during surgery, radiographic parameters correlating with unfavourable outcome should be avoided. The primary aim of the study was to compare radiographic measurements between the injured and the contralateral, uninjured shoulder.
