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.

Comparative StudyLow-profile locking-plate vs. the conventional AO system: early comparative results in wrist arthrodesis.
Total wrist arthrodesis represents a reliable salvage procedure for severe painful conditions of the wrist. To date, wrist arthrodesis using a dorsal plate reaching from the distal radius to the third metacarpal is still recommended. A new implant (APTUS© 2.5 TriLock Wrist Fusion Plate, Medartis Suisse) that does not cross the third carpometacarpal joint (CMCJ-3) has been introduced recently. The purpose of this retrospective study was to compare both implants concerning early functional and clinical results. ⋯ The new implant shows similar functional results compared to the standard procedure. The main advantage of the new implant is the fact that no implant removal is necessary due to the unaffected CMCJ-3. Furthermore the mobility of the CMCJ slightly increased and showed positive impact on hand kinematics.

A two-portal technique using a flexible reamer system is a safe and effective method for transportal anterior cruciate ligament reconstruction.
A flexible reamer system (FRS) for transportal anterior cruciate ligament reconstruction (ACLR) has been developed to overcome the technical challenges of a rigid reamer system. The purpose of this study was to investigate the safety and effectiveness of the two-portal technique using an FRS by evaluating femoral tunnel geometry. ⋯ Retrospective case series; level of evidence, 4.

Optimal rotational positioning of tibial component in total knee arthroplasty: determined by linker surgical technique using a high definition CT.
The rotational alignment of femoral and tibial components is an important determinant of the success of Total Knee Arthroplasty (TKA). The optimal rotational position of the tibial component is still unclear. The purpose of this study was (1) to determine the pre-operative S-TEA (surgical-transepicondylar axis) derived tibialanteroposterior (AP) axis angle and postoperative tibial component axis angle using a "Bird's eye" high-definition CT image in TKA performed by Linker surgical technique; (2) to determine the femorotibial mismatch angle; and (3) to determine the optimal tibial component rotation in a well-aligned femoral and tibial components. ⋯ Level II.
