Inducing life-like distal radius fractures in human cadaveric specimens: a tool for enhanced surgical training.
Surgical education consists often times of a discrepancy between necessary amount of provided operative teaching and amount of organizational and ward duties. Operative education is often cut to a minimum. As public awareness toward surgical competence raises, so must the educational system. Courses that provide pre-fractured cadaveric specimens can facilitate surgical teaching realistically, prior to operating on living patients. The aim of this study is to introduce a realistic distal radius fracture simulation setup. ⋯ A high energetic impulse induced by a custom-made drop-test bench can successfully simulate realistic distal radius fractures in cadaveric specimens with intact soft tissue. Furthermore, these pre-fractured specimens can be utilized in surgical education to provide a teaching experience as realistic as possible without harming living patients.

Total hip arthroplasty without subtrochanteric femoral osteotomy is possible in patients with Crowe III/IV developmental dysplasia: total hip arthroplasty without femoral osteotomy.
We aimed to present our THA technique without femoral shortening osteotomy that we perform for the treatment of coxarthrosis on Crowe type III/IV developmental dysplasia of the hip and to present the early clinical outcomes of our patients. ⋯ Total hip arthroplasty without femoral osteotomy can be considered as a successful method in selected patients with Crowe III/IV coxarthrosis. It provides good clinical outcomes in the early period, reduces surgery duration, has acceptable complication rates, has high prosthesis survival rates.

Direct anterior decompression of L4 and L5 nerve root in sacral fractures using the pararectus approach: a technical note.
To describe a new surgical technique for neurolysis and decompression of L4 and L5 nerve root entrapment after vertical sacral fractures via the pararectus approach for acetabular fractures, and to present four case examples. ⋯ The pararectus approach allows for sufficient visualisation and direct decompression and neurolysis of the L4 and L5 nerve root entrapped in vertical sacral fractures. Although neurologic recovery was not achieved in all patients in this small case series, the approach may be a suitable alternative to posterior approaches and other anterior approaches such as the lateral window of the ilioinguinal approach.

The entry point of intramedullary tibia cutting guide should vary according to the individual tibia morphology in TKA.
In total knee arthroplasty (TKA) using the intramedullary tibial cutting guide (IMTCG), the positioning of the IMTCG is important for accurate tibial bone resection. The aim of this study was to evaluate the ideal entry point of IMTCG and affecting radiologic factors. ⋯ The ideal entry point of IMTCG should vary according to the individual tibial morphology.

Pedobarographic changes during first month after subtalar extra-articular screw arthroereisis (SESA) operation of juvenile flexible flatfoot.
Juvenile flexible flatfoot deformity is a common problem in childhood. In severe cases, the subtalar extra-articular screw arthroereisis (SESA) according to De Pellegrin is a viable and effective option. There are just a few retrospective studies showing long-term outcomes, but the interval right after the surgery has not been described so far, even though the short time of healing is one of the great benefits of this technique. In this study, we examined if the pedobarographic measurements are able to demonstrate functional changes in the month after surgery. ⋯ During bipedal stance, the ground force increased significantly in lateral foot areas (p < 0.001) and decreased in medial areas (p < 0.001). While the force in the medial midfoot remained reduced, in the medial forefoot, the force increased 14 days after surgery (p < 0.05) CONCLUSION: The functional changes after SESA can be accurately assessed using pedobarography. The results indicate morphologic changes of the foot, in particular the development of a longitudinal arch. Post-surgical progression can be monitored and success of the surgery can be verified.
