Reports on medial gastrocnemius myocutaneous (MGM) flaps with extended inferior and posterior boundaries are rare, and information about the MGM flaps with extended anterior boundaries is unavailable. Thus, this study aimed to investigate the vascular anatomical basis and clinical reliability of the modified MGM flap with extended anterior, inferior and/or posterior boundaries. ⋯ Multiple source vessels are the vascular anatomical basis of the modified MGM flap with extended anterior, posterior and/or inferior boundaries. The modification of the MGM flap is feasible and reliable, broadening the applicable scope of the flap. The modified MGM flap can be applied to repair more distal, wider and larger-area defects with a simpler design and procedure.

Fragility fractures without significant trauma of the pelvic ring in older patients have an increasing incidence due to demographic change. Influencing factors other than osteoporotic bone quality that lead to an insufficiency fracture are not yet known. However, it is suspected that the pelvic tilt (PT) has an effect on the development of such an insufficiency fracture. This study explores the influence of the PTs in patients with insufficiency fractures of the posterior pelvic ring. ⋯ The study demonstrates a significant extension of the PT angle of individuals with insufficiency fractures when compared to those with lumbago. The result suggests a potential association between pelvic tilt and fracture susceptibility.

Isolated fractures of the distal fibula mainly affect young, active people. In most cases, fixation is by open reduction with or without casting for six weeks without weight bearing. The current trend is to reduce this period of non-weight-bearing in order to promote earlier functional rehabilitation. ⋯ Two patients had septic complications requiring plate removal and antibiotic treatment and were eventually cured. The use of anatomically contoured locking plates provides strong and stable fixation, allowing immediate full weight-bearing. Such a technique has the advantage of a short recovery time and an early return to work without additional complications.

Despite the recent increase in the use of cephalomedullary nails for trochanteric hip fractures, factors that may be associated with peri‑implant femoral fracture (PIFF) after cephalomedullary nailing for trochanteric fractures remain unknown. We investigated the factors associated with PIFF after cephalomedullary nailing of trochanteric hip fractures in older patients. ⋯ Our results showed that PIFF was more likely to develop among older patients with a clinical history of total knee arthroplasty and A3 fracture. These findings suggest that such patients may require careful follow-up with rigorous assessments after cephalomedullary nailing for trochanteric fractures.

Newer intramedullary (IM) nails have become another option in the fixation of proximal tibia fractures. There is limited data on the successful use of these implants in intra-articular and extra-articular fractures of the proximal tibia, and no studies assessing the ability of these implants to maintain alignment with early weight bearing. Our objective was to determine whether immediate weight bearing after IM fixation, with or without supplemental plate or screw fixation, of proximal third tibial fractures (OTA/AO 41A-C) results in a change in alignment prior to union. 35 patients with 39 proximal tibia fractures from 2015 to 2020, all treated with IM nailing with or without supplemental plate or screw fixation, all made weight-bearing as tolerated following surgery, were included. ⋯ The mean change in MPTA was 0.048 +/- 2.8 degrees (P=0.92), and mean change in PPTA was 0.264 +/- 3.67 degrees. 92.3% of fractures had normal final coronal plane alignment, with MPTA between 85.0 and 90.0 degrees. 89.7% of fractures had normal final sagittal plane alignment, with PPTA between 77.0 and 84.0 degrees. No patients required reoperation for malalignment. In OTA/AO type 41 fractures, immediate weight bearing after IM nail fixation, with or without supplemental plate or screw fixation when indicated, leads to minimal change in final coronal or sagittal alignment, and was well tolerated in most patients.
