Postoperative Outcomes for Plate-Screw Fixation in Adolescent Patients with Ankle Fracture.

BACKROUND: We compared postoperative outcomes in adolescent patients who did and did not undergo plate-screw fixation of at least one of the lateral, medial, or posterior malleoli in ankle fractures. It was hypothesized that using plate-screw fixation would not negatively affect postoperative outcomes. METHODS: All of the preoperative data and postoperative outcomes for 56 patients with ankle fractures aged 12 to 15 years who underwent surgical treatment between January 1, 2007, and December 31, 2017, were reviewed retrospectively. Patients were grouped into plate-screw fixation (n = 15) and non-plate-screw fixation (n = 41) groups and as high- and low-energy trauma patients. RESULTS: There were no significant differences in postoperative outcomes between the plate-screw fixation and non-plate-screw fixation groups. The mean American Orthopaedic Foot & Ankle Society score of high-energy trauma patients was significantly lower than that of low-energy trauma patients (P < .001), and the rate of degenerative change in high-energy trauma patients was significantly higher than that in low-energy trauma patients (P = .008). There were no significant differences between high- and low-energy trauma patients with respect to other postoperative outcomes. CONCLUSIONS: If anatomical reduction is performed without damaging the growth plate, postoperative clinical outcomes may be near perfect regardless of screw-plate fixation use. Postoperative outcomes of adolescent ankle fracture after high-energy trauma, independent of Salter-Harris classification and surgical treatment methods, were negative.

Association of abductor hip muscle atrophy with fall-related proximal femur fractures in the elderly.

OBJECTIVE: The purpose of this study was to evaluate an association between fall-related intertrochanteric or femoral neck fractures and gluteus medius and minimus atrophy, furthermore, to find a correlation of whether any difference between femoral neck or intertrochanteric fracture and degree of muscle atrophy MATERIALS AND METHODS: A retrospective review of 230 patients with intertrochanteric or femoral neck fracture, aged > 65 years, and 60 age- matched controls was performed. We assessed gluteus medius and minimus atrophy and calculated the cross-sectional area (CSA) and ratio of lean muscle to adipose infiltration (M/A ratio) for each muscle. RESULTS: The atrophy scores for the g.medius and g.minimus muscles on the fractured side were significantly higher than scores on the healthy side and scores in the control group. The atrophy scores for the g.medius on the healthy side were not significantly different from scores in the control group. The atrophy scores for g.medius were significantly different between the fractured side and the healthy side for all ages, the atrophy scores for g.minimus was significantly different in the patients aged over 75. There was no significant difference in the following parameters between the fractured side and healthy side of the patients aged 65 - 75 years; the atrophy score, CSA and M/A ratio. The patients have a lower CSA and M/A ratio on the fractured side than on the healthy side and lower CSA and M/A ratio than in the control group. However, there were no significant differences in the M/A ratio between the healthy side and the control group. CSA was not significantly different between the fractured side and healthy side in the male patients and in the patients with lower BMI (<30). There was no significant difference in the atrophy scores between subjects with intertrochanteric versus femoral neck fractures, the CSAs of the g.medius and g.minimus were significantly different between the intertrochanteric fracture and femoral neck fracture groups. CONCLUSIONS: The fractured sides showed greater g.medius and g.minimus muscle atrophy, which may be a predictor of fall-related hip fractures in the elderly. Gluteal muscle volume may be associated with proximal femur fracture subtype.
