抄録	Although the performance of minimally invasive plate osteosynthesis (MIPO) via the anteroinferior approach is increasingly adopted for midshaft clavicle fractures, the influence of fracture morphology on clinical outcomes under a standardized protocol is unclear. We retrospectively analyzed the cases of 54 patients who underwent anteroinferior MIPO for an acute midshaft clavicle fracture (AO/OTA types B1, B2, B3) performed by a single surgeon across three affiliated institutions (2009-2022). We evaluated the clinical outcomes, i.e., the surgical time, incision length, radiographic union, reduction accuracy, range of motion, pain (visual analog scale [VAS]), and complications and compared them among the three AO/OTA subtypes. The mean incision length (3.4 cm) and surgical time (71-79 min) were similar among the groups (both p>0.2). All fractures achieved radiographic union at a mean of 3.5 months. Postoperative alignment and clavicular length were maintained (length reduction −1.0±2.2 mm [B1], −0.5±2.0 mm [B2], −0.6±1.8 mm [B3]; p=0.825; angulation −0.8±3.4°, −1.1±3.1°, −0.3±3.3°; p=0.888). At 3 months, shoulder elevation and abduction were 169°-175° (p=0.079) and 164°-175° (p=0.324). Pain was minimal (100-mm VAS: ≤1 mm; p=0.782). One plate-fatigue failure occurred; no supraclavicular-nerve symptoms were recorded. Anteroinferior MIPO yielded consistent outcomes across AO/OTA types, with excellent union rates, functional recovery, and few complications, indicating that this technique is safe and reproducible for the surgical management of midshaft clavicle fractures.

抄録	Rupture of the extensor pollicis longus (EPL) tendon is a known complication after undisplaced distal radius fracture (DRF). However, no report has revealed the relationship between EPL tendon rupture and the fracture pattern. Thus, this study aimed to investigate the characteristics of fractures at risk of EPL tendon rupture using fracture line mapping of undisplaced DRFs. This study used computed tomography imaging data of undisplaced DRFs with (n=18) and without EPL tendon rupture (n=52). Fracture lines obtained from 3D reconstruction data were drawn manually after matching with a 2D template wrist model. Fracture maps represented the fracture line distribution by superimposing the fracture lines of all 70 patients. Heat maps showed the relative frequency of the fracture lines as a gradual color change. Fracture lines of cases with EPL tendon rupture were concentrated in the proximal border of Lister’s tubercle. By contrast, fracture lines of cases without EPL tendon rupture were relatively dispersed.

抄録	This retrospective study sought to elucidate the incidence rates of roof impaction (RI) and marginal impaction (MI) and radiological and clinical outcomes of open reduction and internal fixation (ORIF) for RI and MI in geriatric acetabular fractures. The cases of 68 patients aged ≥ 65 years (mean 71 years) treated with ORIF were analyzed. MI was present in 12 fractures (67%) and an RI of the weight-bearing surface was present in 24 (46%) of the potential fracture types. Regarding the reduction quality, 54% of the reductions were graded as anatomical, 37% as imperfect, and 9% as poor. In the clinical evaluations of the 45 patients who had > 1-year follow-up (follow-up rate: 66.2%), 18% were graded as excellent, 53% as good, 16% as fair, and 13% as poor. An anatomic reduction was strongly associated with good or excellent clinical and radiological outcomes. CT was superior to radiographs for detecting the residual displacement postoperatively. Postoperative deep infection occurred in four patients. Three patients (6.7%) underwent a total hip arthroplasty conversion due to secondary osteoarthritis of the hip. We recommend ORIF as the preferred surgical treatment option for displaced acetabular fractures in elderly patients.
