BACKGROUND: Neurogenic heterotopic ossification (NHO) is usually treated by surgical excision. Post-operativeinfection (POI) is a possible complication, whose epidemiology, causative organisms, and risk factors are poorly known.We therefore conducted a case-control study to 1) identify the risk factors for POI after surgical excision of NHO at the hip, 2) determine the frequency of POI, 3) and identify the causative organisms. HYPOTHESIS: Risk factors for POI after NHO excision at the hip can be identified...

#4
M Severyns, G Renard, R Guillou, G A Odri, O Labrada-Blanco, J L Rouvillain
Acute quadriceps tendon ruptures disrupt the continuity of the extensor mechanism and must be treated surgically. Tendon reattachment with suture anchors has recently been shown to be biomechanically superior to reattachment through transosseous tunnels. In this context, arthroscopy is an interesting alternative. It can limit postoperative wound healing and infectious complications, while ensuring functional outcomes that are equivalent to standard techniques. The goal of this technical note is to describe an original, reproducible method for arthroscopic reattachment of the quadriceps tendon with suture anchors...

BACKGROUND: Whether pre-operative microbiological sampling contributes to the management of chronic peri-prosthetic infection remains controversial. We assessed agreement between the results of pre-operative and intra-operative samples in patients undergoing single-stage prosthesis exchange to treat chronic peri-prosthetic infection. HYPOTHESIS: Agreement between pre-operative and intra-operative samples exceeds 75% in patients undergoing single-stage exchange of a hip or knee prosthesis to treat chronic peri-prosthetic infection...

BACKGROUND: Arthroscopic meniscal repair limits the medium-term risk of radiological osteoarthritis. Magnetic resonance imaging (MRI) cannot provide an accurate assessment of meniscal healing but may show harbingers of osteoarthritis such as meniscal extrusion. The objective of this study was to assess long-term meniscal extrusion after meniscal repair. HYPOTHESIS: Arthroscopic meniscal suture is not followed by meniscal extrusion and can, therefore, provide good knee function in the long-term...

INTRODUCTION: No rational argument leads to conclude to the benefit or the innocuousness of drainage in non-septic wrist surgery. HYPOTHESIS: The goal of this study was to validate the hypothesis that for those indications drainage is unnecessary. MATERIAL AND METHOD: We reviewed 1001 consecutive cases, concerning 885 patients, 58 years old in average. RESULTS: Out of 1001 procedures, 9 patients were operated on both sides, 145 were operated twice of which 130 for the implantation and then the removal of surgical material...

Acetabular fractures can be challenging to treat, in part because the shape of the fixation plates needs to be adjusted during the surgical procedure. One possibility is to generate a model of the uninjured half of a fractured pelvis with 3D printing, and then pre-contour the fixation plates preoperatively on this model. The purpose of this technical note is to describe how we used 3D printing as an aid to treat acetabular fractures. The quality of the fracture reduction, fracture fixation and time savings were evaluated...

BACKGROUND: Benefits of femoral offset restoration during total hip arthroplasty should be the reduction of bearing surfaces wear, implant loosening and dislocation rates. Modular neck stems ensure offset customization, but fretting corrosion and catastrophic failures are well documented complications. Since clinical evidences are needed to substantiate the effectiveness of femoral offset restoration and promote modular neck choice, we systematically reviewed the literature to ascertain whether femoral offsetitself has a proven clinical influence: 1) on bearing surfaces wear, 2) implant loosening, 3) and dislocation rates...

INTRODUCTION: Treatment of medial tibiofemoral osteoarthritis with a high-tibial osteotomy (HTO) is most effective when the optimal angular correction is achieved. However, conventional instrumentation is limited when multiplanar correction is needed. HYPOTHESIS: Use of patient-specific cutting guides (PSGCs) for HTO provides an accurate correction (difference < 2°) relative to the preoperative planning. MATERIALS AND METHODS: Between February 2014 and February 2015, 10 patients (mean age 46 years (range 31-59), grade 1 or 2 osteoarthritis in Ahlbäck's classification) were included prospectively in this reliability and safety study...

INTRODUCTION: There is no consensus regarding postoperative weight-bearing (WB) assignment after treatment of tibial shaft fractures with an intramedullary nail. This study aims to determine if the postoperative WB assignment after tibia intramedullary nail placement alters healing. METHODS: Closed AO type 42A fractures treated with a reamed statically-locked intramedullary nail over a 10-year period were retrospectively reviewed from injury at 2, 3, 6, 9 and 12 month intervals until union or revision...

REVIEW

Current lengthening techniques are still based on the Ilizarov method and the concept of callotasis. Research and progress in medical devices have led to constant improvement in results. Hexapod fixators allow more precise correction of complex deformities, with shorter learning curve. Associating lengthening by external fixation (EF) to internal fixation (K-wire, intramedullary nail or locking plate) has reduced EF times and complications rates, while improving anatomic and functional results. Lengthening nails provides faster recovery of range of motion and return to activity during lengthening and consolidation, with better psychological tolerance...

BACKGROUND: The Pauwels angle has been used widely, however an accurate evaluation of this angle is difficult because of deformity of the affected lower extremity. Therefore we designed a new measurement of the orientation of femoral neck fracture and applied this in a retrospective study to assess: (1) its reproducibility, (2) its advantages compared with the Pauwels angle, (3) its relationship with the short-term prognosis treated with three cannulated compression screws. HYPOTHESIS: This new measurement is reproducible and has some reference meaning for the treatment of femoral neck fractures...

BACKGROUND: Tuberosity repair in shoulder fracture prosthesis implantation still remains a challenge often leading to poor functional outcomes, despite a variety of materials and suggested suture patterns. We aimed to evaluate, which forces currently used suture and cerclage materials withstand and to assess whether they are useful with regard to stability of reconstruction of tuberosities and which failure modes they display. MATERIAL AND METHODS: Using sheep infraspinatus tendons with attached tuberosities three different suture materials (suture 1: Ethibond size 2; suture 2: Orthocord size 2; suture 3: Fiberwire size 5) and a 0...
