Review Meta AnalysisOutcomes and complications following flexible intramedullary nailing for the treatment of tibial fractures in children: a meta-analysis.
Tibial shaft fractures are common occurrence in children and surgical treatment is sometimes required, particularly in unstable or open fractures, and in polytrauma. The aim of this study was to investigate the available evidence on the efficacy and safety of flexible intramedullary nailing (FIN) for both open and closed tibia fractures in children, exploring the main surgical outcomes and rate of complications. ⋯ FIN offers excellent outcomes for the treatment of paediatric tibia shaft fractures. Patients presenting with an open fracture have a higher but acceptable complication rate. Comparative studies are needed to clarify if other treatments have superior outcomes.

ReviewThe value of radiologic diagnostics in evaluating deltoid integrity in isolated type B ankle fractures: a systematic review of the literature.
Excluding deep deltoid ligament (DDL) rupture in isolated type B ankle fractures is crucial in the decision-making process for surgical or conservative treatment. There is no consensus about the most accurate radiologic diagnostic test to determine medial injury. The aim of this study is to systematically review the literature concerning radiologic diagnostics that evaluate medial injury in adult patients with isolated type B ankle fractures. ⋯ The most accurate and available methods for diagnosing deltoid integrity seem to be the ultrasound and the GS radiograph. Further research is needed to confirm the results of this review.

Femorotibial alignment measured during robotic assisted knee surgery is reliable: radiologic and gait analysis.
Femorotibial alignment is crucial for the outcome of unicompartmental knee arthroplasty (UKA). Robotic-assisted systems are useful to increase the accuracy of alignment in UKA. However, no study has assessed if the femorotibial alignment measured by the image-free robotic system is reliable. The aim of this study was to determine whether measurement of the mechanical femorotibial axis (mFTA) in the coronal plane with handheld robotic assistance during surgery is equivalent to a static measurement on radiographs and to a dynamic measurement during walking. ⋯ There was no significant difference in the femorotibial axis measured by the image-free robotic assistance, from the preoperative radiographs or by gait analysis. The reliability of intra-operative measurements of the frontal femorotibial axis by these robotic-assisted systems is acceptable.

Nonunions about the hip occur as a result of femoral neck, intertrochanteric, and certain subtrochanteric fractures. Treatment of a hip fracture nonunion allows for the choice between hip preservation or arthroplasty. The goal of this study was to examine outcomes of hip-preservation nonunion surgery METHODS: Patients who underwent hip preservation for a fracture nonunion of the femoral neck, intertrochanteric and subtrochanteric region to 1 cm below the lesser trochanter over a 10-year period were identified in our nonunion registry. Patients were followed for a minimum of 1 year. Functional outcomes were recorded at follow-up visits. For comparison regarding surgical and hospital outcomes, a group of 23 patients who underwent conversion total hip arthroplasties (cTHA) at the same academic medical center was reviewed. Quality measures such as length of stay, reoperation, and complications were collected. All statistics analysis utilized IBM SPSS 25 (Armonk, NY) RESULTS: Thirty patients who underwent 30 hip-preserving nonunion surgeries were analyzed and compared with 23 cTHA patients. Twenty-nine nonunions went on to heal (average time to union 6.3 months). There was improvement in functional outcome scores for the hip preservation group between baseline and latest follow-up (p < 0.001). Reoperation was required in five patients (17%), including four failed to heal and required a second repair to gain union and one failure that was converted to THA rather than attempt a second nonunion repair. Hip preservation failures were older than those that healed with the index treatment (p = 0.11). There was no significant difference in hospital length of stay, complication rate, or need for reoperation when compared to cTHA group. ⋯ Hip-preserving surgery is an option that should be considered for patients with nonunion of fractures about the hip. The rates of complications (20.3 vs 17.3%) and reoperation (16.7 vs 17.3%) were equivalent to conversion THA. Excellent outcomes can be achieved in terms of radiographic union and function with hip preservation.

Randomized Controlled TrialA neck-preserving short stem better reconstructs the centre of rotation than straight stems: a computed tomography-based cadaver study.
Short femoral hip stems with a metaphyseal anchoring concept have been designed to treat younger patients with good bone quality. The aim of this study was to reconstruct the centre of rotation and soft tissue balancing and preserve bone in the long-term perspective. ⋯ In this cadaver study, we found that the metaphyseal anchoring, partially neck-preserving short hip stem best reconstructs the ante-torsion and the ante-tilt of the femoral neck. Therefore, it can be a useful stem in younger or active middle-aged patients.
