PURPOSE: The Cobb angle as an objective measure is used to determine the progression of deformity, and is the basis in the planning of conservative and surgical treatment. However, studies have shown that the Cobb angle has two limitations: an inter- and intraobserver variability of the measurement is approximately 3-5 degrees, and high variability regarding the definition of the end vertebra. Scoliosis is a three-dimensional (3D) pathology, and 3D pathologies cannot be completely assessed by two-dimensional (2D) methods, like 2D radiography...

INTRODUCTION: Displaced unstable distal third fractures of the humeral diaphysis are treated surgically through open reduction and internal fixation. Conventionally, surgeons prefer using long plates for secure fixation; however, we performed short plate dual plating for robust fixation that required a smaller incision and less dissection through an anterior approach. In this study, we report the results of dual plating of fractures of the humeral shaft, with radiographic evidence and clinical analysis...

PURPOSE: Severe post-operative pain is one of the main problems after total knee arthroplasty. In this study, we investigated the effect of a peri-articular multimodal drugs injections pre-emptively on post-operative pain control and knee functions following total knee arthroplasty. METHODS AND MATERIALS: This study was a double-blind randomized clinical trial. Eligible cases including 137 patients-aged 30 to 80 years old-were randomly divided into one of two groups: the drug group received a cocktail consisting of bupivacaine hydrochloride, morphine sulphate, epinephrine, and ketorolac...

PURPOSE: The treatment of gluteal muscle contracture (GMC) after failed primary open release surgery has rarely been reported in the literature. GMC is a troublesome health problem in some developing countries, and it can result in the limitation of patients' hip function, leading to the development of inferiority complexes. The aim of this study is to evaluate the effect of arthroscopic revision surgery after failed primary open release on patients with GMC. METHODS: A total of 278 hips of 140 patients who underwent arthroscopic revision procedures after failed primary open surgeries were gathered from the department files...

PURPOSE: Dual mobility (DM) socket has been associated with a low rate of dislocation following both primary and revision total hip arthroplasty (THA). However, little is known about the long-term efficiency of DM in the treatment of THA instability. The purpose of this retrospective study was to evaluate the outcome of a cemented DM socket to treat recurrent dislocation after a minimum of five year follow-up. METHODS: The series included 51 patients with a mean age of 71...

PURPOSE: The treatment of large bone defects represents a significant challenge for orthopaedic surgeons. In recent years, biologic agents have also been used to further improve bone healing. Among these, platelet-rich plasma (PRP) is the most exploited strategy. The aim of the present study was to systematically review the available literature to identify: 1) preclinical in-vivo results supporting the rational of PRP use for bone healing; 2) evidence from the clinical practice on the actual clinical benefit of PRP for the treatment of fractures and complications such as delayed unions and non-unions...

Osteonecrosis of the femoral head affects mainly young patients with high functional needs this increases the risk of dislocation. Dual mobility cups known for low rate of dislocation and high mobility range seems indicated. We evaluate functional efficiency, survival and dislocation rate of dual mobility cup for total hip arthroplasty for osteonecrosis in young patients. Monocentric retrospective clinical study, from 2000 to 2008. With a clinical analysis in pre-operative and over ten years of follow-up of one cohort of patients under 55 years old with an indication of THA for ONFH...

PURPOSE: Early stage adult acquired flatfoot deformity (AAFD) is traditionally treated with osteotomy and tendon transfer. Despite a high success rate, the long recovery time and associated morbidity are not sufficient. This study aims to evaluate the functional and radiological outcomes following the use of the arthroereisis screw with tendoscopic delivered PRP for early stage AAFD. METHODS: Patients with stage IIa AAFD who underwent the use of the arthroereisis screw with tendoscopic delivered PRP with a minimum follow-up time of 24 months were retrospectively evaluated...

REVIEW
Philippe Hernigou, Jacques Pariat
Though the date at which an orthopaedic implant was first used cannot be ascertained with any certainty, the fixation of bone fracture using an iron wire was reported for the first time in a French manuscript in 1775. The first techniques of operative fracture treatment were developed at the end of the 18th and in the beginning of the 19th centuries. The use of cerclage wires to fix fractures was the most frequent fixation at this time. The French Berenger-Feraud (1832-1900) had written the first book on internal fixation...

PURPOSE: Osteolysis in total hip arthroplasty (THA) depends on polyethylene wear and dictates the survival of the prosthesis. Dual mobility in THAs, which is claimed to reduce dislocation risk, has very good long-term clinical results. However, little is known about how the liner wears in this design, compared to the standard single mobility model. METHODS: A comparative study looking at wear of a conventional ultra-high-molecular-weight polyethylene liner, using gravimetric measurement, between dual mobility implants and standard implants, was performed on a simulator in accordance with a normed protocol based on the same dimensions, environmental conditions and stresses...

PURPOSE: Dual-mobility arthroplasty is an alternative to conventional total hip arthroplasty (THA) in appropriately selected, active adults with degenerative, necrotic or post-traumatic hip disease or with revision hip arthroplasty. Numerous papers have been published with results of dual-mobility arthroplasty, but there have been no comprehensive literature reviews that summarise the most recent findings and help the orthopaedic surgeon facing different scenarios in which revision of one or both components of a dual-mobility arthroplasty is indicated...

PURPOSE: This study reports a case series of 44 primary total knee arthroplasties (TKAs) using autogenous morcellised bone grafting for large (≥10-mm-deep) medial tibial defects, which are generally repaired using metal augmentation. The bone-grafting technique is described in detail and the radiological outcomes are presented. METHODS: A total of 44 TKAs were followed up for a mean period of 58 months (range 24-139 months). Multiple drill holes were made in the sclerotic floor of the defect, followed by the impaction of morcellised cancellous bone grafts to fill the defects...

PURPOSE: The purpose of this study was to present the long-term results of treatment of localized pigmented villonodular synovitis (LPVNS) comparing two operative procedures of excision of the lesion-the arthroscopic and the arthroscopically assisted mini-open. We hypothesized that the latter approach allowed for treatment of LPVNS with acceptable recurrence rates, complication rates and functional outcomes. METHODS: Between 1990 and 2006, 21 patients with LPVNS were treated with partial synovectomy through an arthroscopically-assisted mini open technique (group A), and 23 patients were treated with an arthroscopic excision of the lesion (group B)...

PURPOSE: There is evidence that surgeons make different recommendations for people seeking their care than they make for themselves. There may also be differences in pain episodes and management strategies between surgeons and people seeking care, knowledge of which might improve care. We aimed to assess whether the prevalence of non-traumatic pains, treatments and other factors differed between patients and surgeons. MATERIALS AND METHODS: Two-hundred and twenty surgeons, members of the Science of Variation Group (SOVG), and 248 patients seeking care at the Hand Service at a large academic hospital completed a survey regarding the lifetime incidence of non-traumatic pains lasting > one month using short versions of the Pain Catastrophising Scale (PCS-4); Patient Health Questionnaire (PHQ-2); and Short Health Anxiety Inventory (SHAI-5)...

PURPOSE: This study aimed to delineate the infecting micro-organisms identified at the first-time revision for infected THA, analyze pre-operative versus intra-operative findings, as well as intra-operative ones against re-infection micro-organisms. MATERIAL AND METHODS: Microbiological laboratory findings were studied in 73 patients (mean age, 51.93 ± 10.9 years) with chronic periprosthetic hip infection pre-operatively and intra-operatively. Forty-three patients had a two-stage revision THA while 30 patients were treated with a modified resection arthroplasty using the Ilizarov apparatus...

REVIEW
Philippe Hernigou
Surgery in the first half of the nineteenth century was primarily dominated by pain and fear of lethal infections. Therefore, the absolute majority of fractures and dislocations were treated non-operatively. Development of operative treatment of fractures was influenced by three major inventions: anaesthesia (1846), antisepsis (1865) and X-rays (1895). The first to use external fixation is traditionally considered to be Malgaigne (1843). However, his devices cannot be really considered as external fixation...

AIM: We hypothesize that a dual mobility cup can be safely used via the direct anterior approach, without increasing the risk of complications or incorrect positioning. MATERIALS AND METHODS: This retrospective study compared 201 primary total hip arthroplasties using a dual mobility cup performed via direct anterior approach without a traction table, to 101 arthroplasties performed via posterolateral approach. Implant positioning, function scores, and early complications were recorded...
