Correlation of Foot Radiographs With Foot Function as Analyzed by Plantar Pressure Distribution

Abstract

In slipped capital femoral epiphysis (SCFE), cannulated screw fixation is a standard procedure. The aim of this study was to investigate the feasibility of a fluoroscopy-supported navigation system for screw fixation in SCFE. Using a fluoroscopy-enhanced navigation system, a cannulated screw fixation was performed in seven hips of four patients. The navigation system showed a high feasibility in instrument visualization and implant placing. The mean x-ray time was 6.2 seconds. Initial experiences are very promising and show advantages of the fluoroscopy-supported navigation. Considerably reduced x-ray exposure for patients and surgeons is possible. In the future, further efforts will be necessary to develop navigation-specific instruments to enhance the precision of screw positioning.

Current practice in the management of acute/unstable slipped capital femoral epiphyses in the United Kingdom and the Netherlands: results of a survey of the membership of the British Society of Children's Orthopaedic Surgery and the Werkgroep Kinder Orthopaedie

“…In keeping with the literature, which demonstrates a tendency to operate percutaneously and use one screw fixation [3,4,12,[19][20][21][22][23][24], most of our respondents (79%) used a single screw. Interestingly, the use of a second screw was significantly higher in those surgeons with more experience.…”

Fluoroscopy-based computer-assisted navigation for implant placement and hip resurfacing arthroplasty in the proximal femur: the zero-dose C-arm navigation approach

“…[23, 25, 28, 30, 39, 42 -44] report about a signifi cant reduction of radiation time -on average, 64 % -using the navigation system in contrast to the conventional method. Perlick et al [48] only note the mean X-ray time of 6.2 s without comparing with conventional treatment, and two studies do not comment on irradiation [10,35] .…”

“…Chung et al [10] only report about one case of screw fi xation of a femoral neck fracture in a woman with osteogenesis imperfecta. Perlick et al [48] fi xed slipped capital femoral epiphysis in seven hips of four patients. Because this surgical procedure resembles the method of fracture fi xation, this study is integrated in the category of " trauma application. "…”

“…Three studies do not comment on the operation time [10,35,39] . Perlick et al [48] state that the navigated operation was prolonged by 7 min.…”

“…In the past years, feasibility [23, 28, 30, 39, 42 -44] and clinical [10,25,35,48] studies have proven the advantages of 2D fl uoroscopy-based navigated implant placement in the proximal femur over the conventional technique. Nevertheless, a small number of publications confi rm that this technique is used in a limited number of orthopaedic and trauma departments and is restricted to specialised sections with experience in implant navigation.…”
