INTRODUCTION: Open-wedge high tibial osteotomy (OWHTO) is a well-established surgical option for medial compartment osteoarthritis of the varus knee. The initial strength of the fixation plate is critical for successful correction maintenance and healing of the osteotomy site. This study was conducted to verify if a newly designed anatomical plate (LCfit) improves the stability of both the medial implant and lateral hinge area, as well as to evaluate how the metal block contributes to both medial and lateral stability...

BACKGROUND: One of the more commonly used methods of determining the amount of shortening of the fractured clavicle is by comparing the length of the fractured side to the length of contralateral unfractured clavicle. A pre-existing natural asymmetry can make quantification of shortening using this method unreliable. The goal of this study is to assess the side-to-side variation in clavicle length in 100 uninjured, skeletally mature adults. MATERIALS AND METHODS: To assess the side-to-side difference in clavicle length the length of both clavicles of 100 patients on thoracic computed tomography (CT) scans were measured...

INTRODUCTION: Non-prosthetic peri-implant fractures (NPPIFs) are an under-reported entity. Management is challenging because of alterations in anatomy, the presence of orthopaedic implants and phenomena such as stress shielding, disuse osteopenia and fracture remodeling. The aims of this paper were to review patterns of injury, management and outcomes and to propose a classification system to aid further research. MATERIALS AND METHODS: This study is a multi-centered retrospective case series...

BACKGROUND: Glenoid replacement in cases of severe glenoid retroversion (RV) or eccentric wear is challenging. The aim of this study was to evaluate different treatment methods under standardized conditions to assist surgeons in the decision-making process. METHODS: Three treatment options for severe glenoid RV (15°) were compared: (1) no RV correction; (2) complete RV correction; (3) no RV correction and implantation of a posterior augmented glenoid (PAG). A highly standardized implantation protocol using artificial glenoid bones (five per group) was chosen, and a physiologic shoulder movement was applied in a biomechanical setting...

Low back pain is one of the most common diseases of modern civilization. Multimodal pain management (MPM) represents a central approach to avoiding surgery. Short-term results are published rarely and often incomparable because of different treatment concepts. This study compared the subjective and objective parameters as well as the anamnestic and clinical parameters of 445 patients with low back pain before and after inpatient MPM to investigate the influence of this type of therapy on short-term outcome...

The hypothenar hammer syndrome (HHS) is a rare entity of secondary Raynaud's phenomenon. The blunt hypothenar trauma causes a lesion of the vessel wall with a consecutive thrombosis or aneurysm of the ulnar artery at the Guyon's canal. Different risk factors are discussed such as nicotine abuse, or a muscle anomaly in the Guyon's canal. To date, there are five case reports published about muscle anomalies and HHS. We present a case of a 51-year-old shipbuilder with a unilateral HHS on his right dominant hand with a bilateral muscle anomaly...

INTRODUCTION: Injuries of the triangular fibrocartilage complex (TFCC) are of high clinical relevance; however, the clinical evidence for treatment is poor and long-term results are rarely published. The purpose of this study was to evaluate the clinical outcome of symptomatic central traumatic lesions of the TFCC (Palmer 1A) following arthroscopic debridement. MATERIALS AND METHODS: Between 2007 and 2013, 87 patients were arthroscopically diagnosed with Palmer 1A lesion and accordingly treated with debridement...

PURPOSE: To compare the clinical outcomes of double-bundle (DB) single-tibial tunnel technique and double-tunnel technique for ACL reconstruction in patients with knee hyperextension. METHODS: Defined as having constitutional hyperextension of greater than 10°, 56 patients with knee hyperextension who underwent ACL reconstruction were included in this study. To exclude concomitant lesions, preoperative magnetic resonance imaging (MRI) was performed in all knees...

INTRODUCTION: The cervical screw placement is one of the most difficult procedures in spine surgery, which often needs a long period of repeated practices and could cause screw placement-related complications. We performed this cadaver study to investigate the effectiveness of virtual surgical training system (VSTS) on cervical pedicle screw instrumentation for residents. MATERIALS AND METHODS: A total of ten novice residents were randomly assigned to two groups: the simulation training (ST) group (n = 5) and control group (n = 5)...

PURPOSE: Although the spacer block technique has been recommended for the implantation of unicompartmental knee arthroplasty (UKA), there is still a lack of data concerning the resulting component positioning. METHODS: This retrospective study included 193 consecutive patients who had undergone medial UKA using the spacer technique. On the basis of the postoperative long standing radiographs, the coronal component alignment was determined in relation to the mechanical axes and the sagittal component alignment in relation to the anatomical axes of the tibia and femur...

INTRODUCTION: Biomechanical studies have suggested that proximal tibial strain is elevated in UKAs incorporating all-polyethylene tibial components with concern that this leads to premature failure. This study reports minimum 10-year outcomes for a UKA incorporating an all-polyethylene tibial component to determine whether these concerns were realised. MATERIALS AND METHODS: 109 fixed bearing UKAs (97 patients, mean age 68 (range 48-87), 54/97 (56%) female) with all-polyethylene tibial components were followed up for ≥ 10 years with Oxford Knee Scores, Forgotten Joint Scores and Kaplan-Meier analysis...

INTRODUCTION: To evaluate the prevalence of medial collateral ligament (MCL) injury of the knee among ankle-fracture patients and to determine the risk factors associated with MCL injury in this patient group. MATERIALS AND METHODS: 303 patients (303 affected ankles) who underwent surgical treatment for an ankle fracture were assessed. Supination versus pronation injury, Danis-Weber classification, age, sex, body mass index (BMI), limb dominance, and mechanism of injury were reviewed to identify factors related to MCL injury...

INTRODUCTION: Repeated attempts of closed reduction of distal radius fractures (DRF) are performed in the emergency department setting to optimize fracture alignment and avoid surgery. The additional manipulation of the fracture may, however, increase dorsal comminution and lead to loss of reduction in the cast. This retrospective cohort study has investigated the effect of second reduction attempt on fracture alignment and comminution. MATERIALS AND METHODS: Six-hundred-eighteen patients with DRF were treated in the medical center in 2007-2010...

MATERIAL AND METHOD: Between 2006 and 2016, 45 bipolar hemiarthroplasties in trauma surgery, 15 total knee and 19 total hip arthroplasties in patients with Parkinson's disease were performed...

INTRODUCTION: In Denmark, 20% of all registered total hip arthroplasties (THA) from 1995 to 2014 has been patients younger than 60 years with primary idiopathic osteoarthritis (OA). It is speculated that hip malformations may be a major contributor to early OA development. It has been shown that hip malformation may compromise implant position and, therefore, identifying and knowing the incidence of malformations is important. Our aim was to assess the prevalence and type of hip malformations in a cohort of younger patients undergoing THA...

INTRODUCTION: Proximal femur fractures are one of the most common fractures observed in dialysis-dependent patients. Given the large comorbidity burden present in this patient population, more information is needed regarding post-operative outcomes. The goal of this study was to assess morbidity and mortality following operative fixation of femoral neck fractures in the dialysis-dependent elderly. METHODS: The full set of medicare data from 2005 to 2014 was retrospectively analyzed...

INTRODUCTION: Osteopetrosis is a clinical syndrome characterized by the failure of osteoclasts to resorb bone. Affected patients usually suffer from repetitive fractures due to this pathological state. Surgical treatment of these fractures is often complicated by the difficulty of working with the extremely hard and brittle bones. The purpose of this study was to report a case of chronic hangman's fracture in a patient with osteopetrosis who underwent surgery for cervical anterior interbody fusion...
