Does rotational acetabular osteotomy affect subsequent total hip arthroplasty?
Rotational acetabular osteotomy (RAO) has been used successfully in patients with developmental dysplasia of the hip (DDH). However, some patients are forced to undergo total hip arthroplasty (THA) because of the progression of osteoarthritis. We evaluated the effect of previous RAO on the outcome of THA performed for degenerative arthritis secondary to DDH, comparing outcomes for patients with THA and prior RAO versus outcomes for patients with THA and no prior RAO. ⋯ Our midterm results demonstrated that RAO does not lead to higher revision rates, compromised HHSs, or shortened survivorship in eventual THA for DDH.

Plate fixation of extra-articular fractures of the proximal phalanx: do new implants cause less problems?
Limited range of finger motion is a frequent complication after plate fixation of phalangeal fractures. The purpose of this study was to evaluate the results of plate fixation of extra-articular fractures of the proximal phalanx using current low-profile mini-fragment-systems. ⋯ Therapeutic, Retrospective, Level IV.

Case ReportsRecommendations for fracture management in patients with osteopetrosis: case report.
Osteopetrosis is caused by general increase in bone density and obliteration of the medullary canal. Fractures are a frequent complication and their management is considered a challenge due to increased resistance to reaming and screw positioning; reduction maneuvers have to be done more carefully to avoid intraoperative fractures, and there is an increased risk of drill breakage. There is also a higher risk of infection and malunion, which increases the incidence of surgical revisions in this population. ⋯ Fracture fixation in patients with osteopetrosis requires strategies to overcome the technical difficulties found during the procedure. Preoperative planning must include the availability of multiple metal drill bits, electric drills, and bone substitutes, having in mind drilling techniques, drilling speed, and temperature control. Patients should be closely followed to evidence any complications such as infections and malunions.

The effect of flexion balance on functional outcomes in cruciate-retaining total knee arthroplasty.
We investigated the relations between flexion balances and functional outcomes after total knee arthroplasty (TKA). ⋯ These results suggest that total knees with good balanced flexion stability can provide good functional outcomes after TKA.

Restoration of the anatomic position during a meniscal allograft transplantation using pre-existing landmarks.
Accurate sizing and positioning of a meniscal allograft is an important factor for successful outcomes of meniscal allograft transplantation. The objectives of this study were (1) to search a proper rotational landmark, (2) to determine the sagittal slope of meniscus, and, thus (3) to determine the meniscal positioning. ⋯ Line between patellar tendon and tibial spine was a good reference line for a meniscal rotation in the medial meniscus. Among previously introduced reference lines, LMLD showed approximity with a true meniscal rotation. The slope between tibial insertion and mid-portion was significantly different in the lateral meniscus.
