Observational StudyContribution of patient-specific cutting guides to lower limb alignment for total knee arthroplasty.
Patient-specific cutting guides (PSCG) are an extension of preoperative planning for total knee arthroplasty (TKA). We wanted to evaluate their contribution to postoperative lower limb alignment. This study involved primary TKA cases being performed with PSCG between 10/05/2010 and 05/03/2013 and then followed prospectively. The analysis involved the PSCG usage and postoperative measurement of the patient's HKA, medial distal femoral joint angle (MDFA) and medial proximal tibia joint angle (MPTA). Of the 104 eligible cases, 68 were included; 11 of these cases were not performed completely with the PSCG as initially planned. Thus we compared these 11 cases with the 57 where PSCG were used. The preoperative HKA in the included cases was 175.8° ± 7.8; the postoperative angles on average were 179.2° ± 2.9 for the HKA, 89.9° ± 1.6 for the MDFA and 89.0° ± 2.3 for the MPTA. The average postoperative deviation from the target values was 2.22° ± 2.14 for the HKA angle, 1.07° ± 1.15 for the MDFA and 1.66° ± 1.90 for the MPTA. There were no significant differences between the two groups in any of the measurements. The lower limb alignment goal was achieved in 50 cases (73%), with 41 of these achieved with PSCG (82%). Of the 18 cases where the target was not achieved, PSCG were used 16 times (88%). In this study cohort, lower limb alignment was not significantly closer to an HKA of 180° or achieved more often with the use of PSCG versus standard instrumentation. Since the results of the two groups can be superimposed, we found no evidence that use of PSCG improves postoperative lower limb alignment. LEVEL OF EVIDENCE IV. ⋯ Cohort.

The progression of lumbar curves in adolescent Lenke 1 scoliosis and the distal adding-on phenomenon.
The postoperative deterioration of the curve below spinal fusion instrumentation resulting in a distal adding-on (AO) phenomenon in idiopathic adolescent scoliosis (IAS) frequently requires surgical revision with disappointing secondary clinical results. ⋯ 4, retrospective study.

Case ReportsComplete traumatic backout of the blade of proximal femoral nail antirotation: a case report.
This article presents a rare case of traumatic complete expulsion of the helical blade after successful treatment of an intertrochanteric fracture with proximal femoral nail antirotation (PFNA). A 94-year-old woman sustained an intertrochanteric fracture of the left femur. Fracture fixation was performed by using PFNA-II. ⋯ The PFNA-II was removed and a cemented bipolar hemiarthroplasty was performed. At 5 months after surgery, the patient was able to walk with a walker without pain. Traumatic complete expulsion of the blade should be considered as a possible complication of PFNA/PFNA-II.

The ilio-inguinal approach for recent acetabular fractures: ultrasound evaluation of the ilio-psoas muscle and complications in 24 consecutive patients.
The ilio-inguinal approach is used to achieve internal fixation of acetabular fractures. Although the outcomes of this procedure have been extensively reported, information is lacking on potential complications. More specifically, the effect on the ilio-psoas muscle, whose iliac attachments are almost completely released, has not been accurately evaluated. ⋯ Level IV, retrospective study.
