PURPOSE: Concurrent carpal tunnel syndrome and pronator syndrome are rarely considered and the proximal compression sites are easily overlooked. We retrospectively studied 21 concurrent cases in our series from 2009 to 2015 and report the results. PATIENTS AND METHODS: The typical symptoms were pain, tingling, and numbness of the radial 3½ digits. If paresthesia involved the thenar eminence and proximal forearm pain was noted in cases of carpal tunnel syndrome, carpal tunnel syndrome combined with pronator syndrome was considered...

INTRODUCTION: The majority of proximal humeral fractures in the skeletally immature are treated non-operatively. Operative indications vary but are largely based on degree of displacement. Non-union is rare. Non-operatively treated fractures are typically monitored radiographically to assess healing. HYPOTHESIS: We hypothesize that the decision to treat fractures operatively is made at the time of first imaging and that follow-up X-rays do not lead to a change in management...

INTRODUCTION: Subjects with Down syndrome (DS) are known to be affected by various foot deformities. Despite the fact that some of these deformities have been reported in the literature, a more comprehensive description would be of benefit. The aim of this study is to investigate the prevalence of known foot deformities in patients with DS and of other previously non-described foot anomalies in this population. HYPOTHESIS: Subjects with DS have an increased prevalence of foot deformities compared to control subjects...

: InstructionAnterior cervical discectomy and fusion (ACDF) is a well-accepted surgical management strategy for radiculopathy and/or myelopathy.However, complications sometimes required subsequent surgery at the operated and adjacent levels. Artificial cervical disc replacement (ACDR) has been accepted as the most extensive non-fusion procedure and is designed to preserve motion. However, some specific complications can resultinsubsequent surgery, thus attracting the attention of investigators...

INTRODUCTION: The incidence of periprosthetic fracture after total knee arthroplasty (TKA) is increasing, and treatment is becoming more necessary. In periprosthetic tibial fracture, the stem of the tibial component largely occupies the medullary canal of the proximal tibia, which limits the selection of implants. The purpose of this study was to evaluate the effectiveness of the minimally invasive plate osteosynthesis (MIPO) technique with locking plates for periprosthetic tibial fractures after TKA...

BACKGROUND: Rates of dislocation following primary total hip arthroplasty (THA) vary from 0.5 to 10%. Dual-mobility cups in THA demonstrate increased stability. Clinical outcomes following THA with dual-mobility cups have been reported, but gait has not been assessed. Therefore we performed a retrospective case control study to answer: (1) is gait better in patients following THA with a dual-mobility cup than in frail, elderly patients of the same age? (2) Are clinical outcomes better in patients following THA with a dual-mobility cup than in frail, elderly patients? (3) What is the dislocation rate following THA with a dual-mobility cup? HYPOTHESIS: We hypothesized that patients who underwent THA with a dual-mobility cup have a better gait compared to frail, elderly patients of the same age...

BACKGROUND: In the normal adult spine, a link between thoracolumbar and cervical sagittal alignment exists, suggesting adaptive cervical positional changes allowing horizontal gaze. In patients with thoracic hyperkyphosis, cervical adaptation to sagittal global alignment might be different from healthy individuals. However, this relationship has not clearly been reported in hyperkyphotic deformity. PURPOSE: The purpose of this study was to identify cervical sagittal alignment types observed on radiographs in young adults with thoracic hyperkyphosis...

INTRODUCTION: The complications related to revision for acetabular component protrusion with material migrating into the intrapelvic region remain rare but potentially serious. Today, the literature reports no epidemiological data on the subperitoneal approach (SPA) in revision total hip arthroplasty (RTHA) for protrusion. Therefore we conducted a retrospective study on a large revision arthroplasty database to answer the following questions: 1) What is the frequency of this approach in this population? 2) What are the factors related to this procedure? 3) Is morbidity and mortality of the SPA higher than for an isolated conventional approach? HYPOTHESIS: Major protrusions with material in the superomedial quadrant (SMQ)have a higher probability of being operated using a SPA...

In comminuted fracturesof the intercondyloid eminence of the tibial spine, the quality of the reduction and the arthroscopic fixation, notably adjustable suture buttonfixation, is sometimes disappointing with reduction defects of theanterior bone block. In the Speed-Bridge technique, the two traction sutures of the adjustable button fixation are replaced with two braided sutures of different colors. After the button is placed above the eminence, reduction is obtained by tightening the loop of the button. The accessory communitive fragments are then packed in the depressionaround the main fragment...

PURPOSE: Report the results of surgical treatment of post-traumatic atlantoaxial rotatory fixation (AARF) due to C2 articular facet fracture in adults. MATERIAL AND METHODS: The records of five patients treated since 2009 for AARF due to a C2 articular facet fracture were analyzed retrospectively. Three women and two men with an average age of 60 years (27-82) were included, one of whom initially had neurological deficits. In all cases, the surgical strategy consisted of posterior fixation: Harms-type in four cases and trans-articular with hooks in one case...

Oxidized zirconium (Oxinium™; Smith& Nephew, Memphis, TN, USA) articulatedwith polyethylene in total hip arthroplasty (THA) appeared to have the potential to reduce wear dramatically. The thermally oxidized metal zirconium surface is transformedinto ceramic like hard surface that is resistant to abrasion. The exposure of soft zirconium metal under hard coverage surface after the damage of oxidized zirconium femoral head have been described.It occurred following joint dislocation or in situ succeedingdisengagement of polyethylene liner...

REVIEW
Yves Tourné, Christian Mabit
Capsule/ligament lesions of the lateral compartment of the ankle lead to lateral laxity, which is a prime contributor to chronic ankle instability. Lateral ligament reconstruction stabilizes the joint. Exhaustive preoperative clinical and paraclinical work-up is essential. The present article classifies, presents and criticizes the main techniques in terms of long-term stabilization and reduction of osteoarthritis risk. Anatomic ligament repair with reinforcement (mainly extensor retinaculum) or anatomic ligament reconstruction are the two recommended options...

REVIEW
Guy Piétu, Mathieu Ehlinger
Fractures of the distal femur remain a daunting challenge. Since 1970, operative treatment has been recommended. Unfortunately it is fraught with complications, and techniques have been developed to limit incidence of non-union, infection and stiffness. A soft-tissue friendly approach is the key point, with minimally invasive surgery as the ultimate goal: its biological and anatomical advantages have; been demonstrated, but clinical studies have been less convincing, being based on historical series. At present, retrograde nailing and minimally invasive percutaneous plate osteosynthesis (ideally by locking plate) are the two main techniques...

REVIEW
Jérôme Sales de Gauzy
Pediatric orthopedic surgery in humanitarian aid is conducted mainly in cooperation with emerging countries. Each mission is different, and depends on numerous parameters such as the country, the frequency of such missions, the pathologies encountered, the local structure and team, and the non-governmental organization (NGO) involved. Pathologies vary in etiology (tuberculosis, poliomyelitis) and severity. Each mission requires the presence of an experienced surgeon. Working conditions are often rudimentary...

In the treatment of unstable pelvic ring fractures, external fixators have the limitation of not adequately stabilizing the injured posterior elements. This article presents a novel and simple technique of temporary external fixation of the pelvic ring, able to produce compression of both the anterior and posterior pelvic elements. A curved flexible carbon-fiber rod is used, pre-tensioned before attachment to supra-acetabular Schanz screws. Although more extensive clinical experience is required, favorable preliminary results in a series of 13 patients with unstable pelvic fracture were encouraging: the aim of closing the posterior and anterior elements of the pelvic ring was achieved in all cases treated with this technique, and 12 patients survived...

BACKGROUND: Risk factors for hemorrhage in patients with pelvic ring fracture have been widely reported. Because there are many risk factors, it is thought that prediction accuracy of hemorrhage in cases of pelvic ring fracture could be improved by using a scoring system. HYPOTHESIS: We investigated the risk factors for massive hemorrhage (MH) and created a novel predictive score of MH in pelvic ring fractures. MATERIAL AND METHODS: We retrospectively reviewed patients with pelvic ring fractures (Abbreviated Injury Score≥3 and age≥16 years) from January 2007 to June 2015...

INTRODUCTION: Adopting the direct lateral (DL) instead of the posterolateral (PL) approach in hip arthroplasty for femoral neck fracture (FNF) patients could lower the rate of prosthetic dislocation. However, little is known about how the approach influences the functional outcome. HYPOTHESIS: We hypothesized that both approaches would give comparable results. MATERIAL AND METHODS: In a prospective cohort study, we enrolled 185 hips (183 patients, 128 women, median age 84 years) with a displaced FNF...
