INTRODUCTION: Cam morphology is a strong risk factor for the development of hip pain and osteoarthritis. It is increasingly thought to develop in association with intense physical activity during youth; however, the aetiology remains uncertain. The study aim was to characterise the effect of physical activity on morphological hip development during adolescence. METHODS: Cross-sectional study of individuals aged 9-18 years recruited from Southampton Football Club Academy (103 male) with an age-matched control population (52 males and 55 females)...

INTRODUCTION: Neck enlargement is well described in patients treated with self-expandable endografts for abdominal aortic aneurysms. Double endografting (ie, overlapping of stent grafts) occurs in patients with proximal cuffs or bifurcated to monoiliacal configuration conversions. When the aortic neck of patients receives 2 suprarenal fixation endografts, it may behave differently in terms of radial force and interaction of additional suprarenal stents extending to the visceral aorta...

Aluminum alloy sheets have been widely used to build the thin-walled structures by mechanical clinching technology in recent years. However, there is an exterior protrusion located on the lower sheet and a pit on the upper sheet, which may restrict the application of the clinching technology in visible areas. In the present study, an improved clinched joint used to join aluminum alloy sheets was investigated by experimental method. The improved clinching process used for joining aluminum alloy evolves through four phases: (a) localized deformation; (b) drawing; (c) backward extrusion; and (d) mechanical interlock forming...

Neglected or incorrect treatment of pediatric radial neck fractures may lead to symptomatic malunions. Computer-assisted corrective osteotomies with patient-specific guides have been proposed as a promising technique for the reconstruction of malunited long bone deformities. The aim of this study was to evaluate the accuracy and clinical outcome of this technique in children with malunited fractures of the radial neck. Four children (two male, two female; mean age 12 (10-16) years) underwent computer-assisted closing wedge osteotomy of the radial neck...

Genetic factors contribute to the risk of bone fractures, partly because of effects on bone strength. High-resolution peripheral quantitative computed tomography (HR-pQCT) estimates bone strength using micro-finite element analysis (µFEA). The goal of this study was to investigate if the bone failure load estimated by HR-pQCT-based µFEA is heritable and to what extent it shares genetic regulation with areal bone mineral density (aBMD). Bone microarchitecture was measured by HR-pQCT at the ultradistal tibia and ultradistal radius in adults from the Framingham Heart Study (n = 1087, mean age 72 years; 57% women)...

BACKGROUND: Radial head and neck fractures are the most common elbow fracture in the general adult population; however, the optimal treatment for radial head fractures remains a topic of ongoing clinical controversy. The purpose of this study was to determine the rate of return to function, complications, and reoperation following operative management of unstable radial head fractures in a young, active patient population with intense upper extremity demands. METHODS: A military health care database was queried for all US military servicemembers undergoing open reduction with internal fixation (ORIF; Current Procedural Terminology [CPT] code: 24665) and radial head arthroplasty (RHA; CPT code: 24666) between 2010 and 2015...

BACKGROUND: The scope of microvascular tissue transfer in the Head and Neck reaches from coverage of simple soft tissue defects to complex 3-D reconstructions using multiple or chimeric flaps. This paper summarises the presentation given at the Congress of the French Society of Oral and Maxillofacial Surgery in Marseille 2017. It was the aim of our work to add further elements to this wide spectrum of reconstructive possibilities. METHODS: For patients with small intraoral soft tissue defects in whom the use of a radial forearm flap would not be justified because of its donor site morbidity, but who nevertheless would take a benefit from a small free flap, we used mini-perforator flaps from the lower leg...

Primary malignant melanoma in the tongue is very uncommon disease that is considered low in comparison to cutaneous melanoma. In this report, the authors described a case of the hemitongue reconstruction with fasciocutaneous free flap on the patient who suffered from the malignant melanoma primarily originating from the base of the tongue that was treated with surgery and radiotherapy but developed a lung metastasis. A 76-year-old man was referred to the otorhinolaryngology clinic after complaining of a painful mass present for 3 months on the right side of the tongue...

BACKGROUND: Necrotizing fasciitis (NF) is a life-threatening infection requiring extensive debridement that may necessitate amputation. Free tissue transfer (FTT) is an option for reconstruction in difficult cases. Currently, only case reports have described FTT in the setting of NF, and comprehensive evidence on flap outcomes is lacking. The present study characterizes outcomes in patients with FTT following NF. METHODS: All patients admitted with NF between January 1, 2005 and December 31, 2011 to our level 1 burns/trauma referral center were retrospectively reviewed...

CONTEXT: The increased fracture risk associated with type 1 diabetes mellitus (T1DM) remains unexplained by traditional risk factors such as low areal bone mineral density (aBMD). Nonetheless, few data exist on other determinants of bone strength in T1DM, including volumetric BMD (vBMD) and bone geometry. OBJECTIVE: We compared areal and volumetric bone parameters and cortical bone geometry in adult T1DM patients and gender- and age-matched controls. DESIGN: Cross-sectional study including 64 adult T1DM patients (38 men, 41...

Radial forearm free flaps are commonly used for soft-tissue reconstruction after resection of head and neck cancer. It is perfused by the radial artery, leaving the ulnar artery for perfusion of the hand and digits. The absence of distal ulnar artery and associated superficial palmar arch, however, has not been reported in cadaveric dissection. We report a case of unilateral ulnar artery flow absence, detected by Allen's test, during preoperative preparation for a radial forearm free flap. Based on the simplicity, safety, and ease, we recommend Allen's test to be performed preoperatively on every patient for whom such a flap is a consideration...

BACKGROUND: Pediatric patients with olecranon fractures are uncommon. The tension band suture technique was introduced to reduce the burden of implant removal and other complications. However, to our knowledge, early range of motion (ROM) exercise has not been introduced in this population of patients. Double Vicryl loops and knots with 2 cross-pins are used to maintain the benefits of the tension band suture technique and to enhance fixation tensile strength. We believe that early ROM exercises could be achieved without nonunion or fixation failure...
