The use of tibial tuberosity-trochlear groove indices based on joint size in lower limb evaluation

Purpose The correlation between tibial tuberosity-trochlear groove distance (TT-TG) and joint size, taking into account several different parameters of knee joint size as well as lower limb dimensions, is evaluated in order to assess whether TT-TG indices should be used in instead of absolute TT-TG values. Methods This study comprised a retrospective analysis of knee CT scans, ...

Retrieval evidence of impingement at the third articulation in contemporary dual mobility cups for total hip arthroplasty

Purpose We aimed to assess polyethylene liners of retrieved hips of one design of a dual mobility (DM) cup liner and two designs of femoral stems to better understand the role of femoral stem design on polyethylene impingement. Methods This was a case-control study involving 70 retrieved highly cross-linked polyethylene (X3) liners used with ABGII (n = 35) and Rejuvenate (n = 35) ...

Knee joint preservation surgery in osteosarcoma using tumour-bearing bone treated with liquid nitrogen

Purpose To preserve the joint structure in order to maintain good limb function in patients with osteosarcoma, we perform epiphyseal or metaphyseal osteotomy and reconstruction using frozen autografts that contain a tumour treated with liquid nitrogen. There are two methods of using liquid nitrogen-treated autografts: the free-freezing method and the pedicle-freezing method. The ...

The fifty highest cited papers in anterior cruciate ligament injury

Introduction The anterior cruciate ligament (ACL) is one of the most common injured knee ligaments and at the same time, one of the most frequent injuries seen in the sport orthopaedic practice. Due to the clinical relevance of ACL injuries, numerous papers focussing on this topic including biomechanical-, basic science-, clinical- or animal studies, were published. The purpose of ...

Two stage revision hip arthroplasty in periprosthetic joint infection. Comparison study: with or without the use of a spacer

Purpose The aim of this study was to compare two methods of two-stage surgery for PJI (periprosthetic joint infection) after THA (total hip arthroplasty): one with and one without the use of an antibiotic-loaded cement spacer. Methods This retrospective study was performed on 99 consecutive patients (99 hips) with a minimum follow-up of 24 months. Patients were divided into two ...

Patient-specific instrumentation improves alignment of lateral unicompartmental knee replacements by novice surgeons

Purpose Patient-specific instrumentation (PSI) has the potential to offer numerous benefits—not least of all, improved resection accuracy; but its potential has not been realised in clinical studies. An explanation may be the focus of such studies on the total knee replacement (TKR—a common procedure, with which surgeons are generally very familiar. Consequently, we sought to ...

Biomechanical evaluation of straight antegrade nailing in proximal humeral fractures: the rationale of the “proximal anchoring point”

Purpose Varus failure is one of the most common failure modes following surgical treatment of proximal humeral fractures. Straight antegrade nails (SAN) theoretically provide increased stability by anchoring to the densest zone of the proximal humerus (subchondral zone) with the end of the nail. The aim of this study was to biomechanically investigate the characteristics of this ...

Historical review of arthroscopic surgery of the hip

Background & purpose Increasing our appreciation of the historical foundations of hip arthroscopy offers greater insight and understanding of the field’s current and future applications. This article offers a broad history of the progress of hip arthroscopy. Methods Hip arthroscopy’s development from the early technologies of endoscopy to the present day is described through a ...

Patient sexual function and hip replacement surgery: A survey of surgeon attitudes

Purpose To explore practises of orthopaedic surgeons (and residents) in addressing sexual function (SF) in patients before and after total hip arthroplasty (THA). Methods A 26-item questionnaire was sent to health professionals (n = 849); 526 (62.0%) responses were included in the analyses. Results About 78% of the respondents (77.5%) almost never addressed SF. The most mentioned ...

Clinical application of bone morphogenetic proteins for bone healing: a systematic review

Purpose This paper documents the existing evidence on bone morphogenetic proteins (BMPs) use for the treatment of bone fractures, non-union, and osteonecrosis, through a review of the clinical literature, underlying potential and limitations in terms of cost effectiveness and risk of complications. Methods A systematic review was performed on the PubMed database using the following ...

Current concepts in the diagnosis and management of extra-articular hip impingement syndromes

Purpose Extra-articular hip impingement syndromes encompass a group of conditions that have previously been an unrecognised source of pain in the hip and on occasion been associated with intra-articular hip impingement as well. As arthroscopic techniques for the hip continue to evolve, the importance of these conditions has been recognised recently and now form an important part of ...

Measurement considerations on examiner-dependent factors in the ultrasound assessment of developmental dysplasia of the hip

Purpose The standardized sonographic hip screening according to Graf has increased reliability and comparability of measurements in the screening of developmental dysplasia of the hip (DDH). However, examiner dependent factors have been discussed to influence sonographic measurements. The objectives of this study were to examine the tolerance of the transducer positioning and to ...

Use of internal lengthening nails in post-traumatic sequelae

External fixators are a well-established modality for treating fractures with bone defects, leg-length discrepancy, malunion, nonunion and other post-traumatic consequences. However, use of internal lengthening rods has remarkably increased recently for post-traumatic conditions. The main advantage of internal lengthening rods is eliminating pin-site complications. Internal ...

Intercalary frozen autograft for reconstruction of malignant bone and soft tissue tumours

Purpose In 1999, we developed a technique using frozen autografts—tumour-containing bone treated with liquid nitrogen—for the reconstruction of malignant bone tumours. The purpose of this study was to evaluate the functional and oncological outcomes of frozen autografts for intercalary reconstruction of malignant bones and soft tissue tumours. Methods This retrospective study was ...

The push-through total femoral prosthesis offers a functional alternative to total femoral replacement: a case series

Purpose Oncologic resections or complications of segmental femoral prostheses can result in severe bone loss of the femur for which a total femoral prosthesis (TFP) is required. This study assesses whether the loss of stability and function caused by the loss of muscle attachments can be improved by using a push-through total femoral endoprosthesis (PTTF), because it saves parts of ...

Biomechanical comparison of anatomical plating systems for comminuted distal humeral fractures

Purpose Six different mono-axial and poly-axial distal humeral plating systems with an anatomical plate design were compared. The aim of the biomechanical tests was to examine differences regarding system stiffness, median fatigue limit, and failure mechanisms. Methods Different configurations of two double plate fixation systems by two manufacturers for the treatment of complex ...

Being overweight has limited effect on SCARF osteotomy outcome for hallux valgus correction

Purpose The purpose of this study was to investigate the association between body mass index (BMI) and the results of SCARF osteotomy of the first metatarsal for hallux valgus (HV) correction, as the literature on this is scant. Methods This prospective study was carried out between 2011 and 2015. One hundred and thirty-three patients diagnosed with moderate to severe HV underwent ...
