Background and Objectives: Anterior sacroiliac fracture dislocation (ASFD), also known as locked pelvis, is a rarely reported diagnosis. The types of ASFDs are often misdiagnosed as lateral compression fractures due to the presence of crescent fractures. In this study, we distinguished ASFD from lateral compression fractures (LC 2) and studied their characteristics. Materials and Methods: This is a retrospective study involving patients from a Level 1 trauma center. Fifty-nine patients under the age of 65 years with crescent fractures caused by a high-energy mechanism were investigated. Results: The incidence of ASFD was 25% (15 of 59) in patients with crescent fractures. Among the 15 patients, 6 had override of the ilium over the sacrum, inhibiting reduction in the sacroiliac joint. Pre-operative radiographic evaluations revealed that vertical displacement of the ASFD was larger than that of lateral compression fracture (LC 2) in the outlet view (mean 9.5 vs. 1.9 mm, p = 0.013), and the pelvic asymmetry ratio was larger in ASFD (mean 7.8 vs. 4.1, p = 0.006) in the pelvis AP view. All patients achieved union after surgery. Post-operative radiography showed no significant vertical displacement difference. There was no difference in vascular injury or hemodynamic instability requiring embolization or preperitoneal pelvic packing (PPP) between the two groups. Conclusions: Patients with ASFD have greater vertical displacement and asymmetry compared to patients with LC 2 fractures. These fractures must be distinguished for appropriate reduction and anterior plate fixation.

METHODS: A 10-year-old girl presented after closed reduction of an elbow fracture dislocation. She demonstrated intact vascularity but a dense median nerve palsy. Preoperative magnetic resonance neurography (MRN) precisely mapped the median nerve entrapped within the medial epicondylar fracture. Intraoperatively, the median nerve was freed preceding reduction and fracture fixation. Postoperatively, neurological symptoms completely resolved, and she regained full elbow function.
CONCLUSIONS: Median nerve injury can present without associated vascular injury. In this case, MRN was helpful in preoperatively illustrating the spatial relationship between the median nerve and the medial epicondyle.

METHODS: We present a 17-year-old male patient with an initially missed posterior sternoclavicular fracture dislocation who presented with symptoms related to thrombotic emboli arising from a pseudoaneurysm. He was treated 6 weeks after injury with a figure-of-eight tendon allograft repair with good clinical outcomes.
CONCLUSIONS: This is a unique presentation that highlights the significant risk of a missed diagnosis, life-threatening complications that may ensue, and biomechanically superior surgical intervention.

UNASSIGNED: Despite extensive literature dedicated to determining the optimal treatment of isolated greater tuberosity (GT) fractures, there have been few studies to guide the management of GT fracture dislocations. The purpose of this review was to highlight the relevant literature pertaining to all aspects of GT fracture dislocation evaluation and treatment.
UNASSIGNED: A narrative review of the literature was performed.
UNASSIGNED: During glenohumeral reduction, an iatrogenic humeral neck fracture may occur due to the presence of an occult neck fracture or forceful reduction attempts with inadequate muscle relaxation. Minimally displaced GT fragments after shoulder reduction can be successfully treated nonoperatively, but close follow-up is needed to monitor for secondary displacement of the fracture. Surgery is indicated for fractures with >5 mm displacement to minimize the risk of subacromial impingement and altered rotator cuff biomechanics. Multiple surgical techniques have been described and include both open and arthroscopic approaches. Strategies for repair include the use of transosseous sutures, suture anchors, tension bands, screws, and plates. Good-to-excellent radiographic and clinical outcomes can be achieved with appropriate treatment.
UNASSIGNED: GT fracture dislocations of the proximal humerus represent a separate entity from their isolated fracture counterparts in their evaluation and treatment. The decision to employ a certain strategy should depend on fracture morphology and comminution, bone quality, and displacement.

CONCLUSIONS: Monteggia fracture is a complex fracture consisting of a proximal ulna fracture with a dislocation of the radial head. This review article highlights the relevant anatomy, clinical evaluation, classification, surgical management, recent innovation, and advancements with treating these injuries. A thorough understanding of these fractures allows for detailed operative plans and reconstitution of normal anatomy.

Electrical injuries are common phenomena in developing countries, due to inadequate safety measures followed during day-to-day electrical repairs. Workplace injuries account for 20% of these. In some severe cases, electrical injuries lead to burns, indirect fracture dislocations, speech impairments, etc. Falls due to electrical injuries leading to secondary complications are very common and, even though not very severe, they do require immediate treatment and adequate rehabilitation. A 53-year-old male suffered a shoulder injury following an electrical shock. The patient also experienced irritation and speech disturbances. Examination revealed a reduced range of shoulder joints and tightness of muscles of the shoulder complex. Physiotherapy intervention included counseling for the patient and his family members, energy conservation methods for ease in daily activities, a rehabilitation protocol, and modified music therapy. Outcome measures used to assess the progression constituted the Shoulder Pain and Disability Index (SPADI), the Tampa Scale for Kinesiophobia (TSK), and the Depression and Anxiety and Stress Scale. Rehabilitation with adjunct therapy is effective in the overall improvement of the patient\'s condition concerning their mental health as well as physical health by early strength training.

METHODS: Retrospective study of data abstracted from the Diagnosis Procedure Combination (DPC) database.
OBJECTIVE: This study aimed to investigate the effects of surgery in the early phase.
BACKGROUND: The optimal timing of surgery for cervical fracture dislocation (CFD) remains unclear because only a few clinical studies with approximately 100 patients have been published.
METHODS: This study included 4,653 adult patients with a definitive diagnosis of CFD from the DPC database. The database contains nationwide inpatient data collected from >1,000 acute care hospitals in Japan. The DPC database contains information regarding hospitalization, such as diagnosis, treatment, medical history, complications, and hospitalization outcomes. This study identified 460 pairs of patients after one-to-one propensity-score matching (PSM). Treatment outcomes were compared between patients who underwent surgery for CFD within 72 hours (early group) and later (delayed group) after admission. The main outcomes included 30-day mortality, inhospital death, and major complications. The secondary outcomes were improvement in the Barthel index, length of hospital stay, and discharged home rate.
RESULTS: After adjusting for PSM, the early group had a significantly higher 30-day mortality rates than the delayed group (3.0% vs. 0.4%, p=0.006). In the multivariate logistic regression analysis after PSM, the early group was associated with an increased risk of 30-day mortality (odds ratio, 8.05; 95% confidence interval, 2.15-5.26; p=0.007).
CONCLUSIONS: This study indicated that early surgery for CFD resulted in increased 30-day mortality.

OBJECTIVE: This study aims to evaluate the outcomes of open reduction and internal fixation (ORIF) for chronic perilunate dislocations using single-stage, two-stage, and salvage procedures. The study also compares these approaches with each other and with results from existing literature.
METHODS: A total of 15 patients with chronic perilunate injuries from 2013 to 2019 were included in the study. Pre-operative and post-operative assessments were conducted using plain radiographs, with CT scans performed selectively for detailed morphology and fracture pattern analysis. Among the patients, 13 underwent ORIF, while 2 underwent salvage procedures. Among the ORIF cases, single-stage procedures were performed in 4 patients, and two-stage procedures in 9 patients. External fixators, including unilateral uniplanar external fixators (UUEF) and bilateral uniplanar external fixators (BUEF), were applied in 5 and 4 patients, respectively. Our methodology of treating chronic perilunate injuries has evolved over the years. We started with single stage ORIF then graduated to a two staged procedure initially using a external fixator as a carpal distractor applied only on the radial side and finally settling down with bilateral carpal distraction using external fixators both on the radial and ulnar sides.
RESULTS: Among the 15 patients, 3 were lost to follow-up. Of these, one underwent four-corner fusion, while the remaining two had UUEF. The mean time interval between injury and surgery was 3.60 months. The post-operative mean scapholunate angle measured 52.46°, with a negative radio-lunate angle (indicating flexion) observed in two patients, while others showed a positive angle (indicating extension). Two cases exhibited nonunion and avascular necrosis (AVN) of the scaphoid, while one case presented with lunate AVN. Mid-carpal and radio-carpal arthritis was observed in 4 and 2 patients, respectively. Functional outcomes were evaluated using Mayo\'s wrist score categorized as good for two-stage BUEF cases and satisfactory for UUEF and single-stage procedures.
CONCLUSIONS: Staged reduction utilizing the BUEF followed by open reduction has demonstrated superior outcomes when compared to UUEF, single-stage open reduction and salvage procedures.

Lisfranc injuries are rare but severe injuries of the foot. They range from ligament sprain to complex fracture dislocations. Etiologically, a distinction is made between indirect and direct force and between high-energy and low-energy trauma. Inadequate diagnostics (injuries overlooked or misinterpreted) can lead to painful posttraumatic osteoarthritis, chronic instability and deformity of the foot. A fracture, malalignment and unclear findings in conventional radiological diagnostics necessitate computed tomography imaging including 3D reconstruction. Lisfranc injuries are often associated with accompanying pathologies of the foot that also need to be addressed. Only stable non-displaced fractures can be treated conservatively. Depending on the injury pattern, surgical treatment is performed percutaneously, minimally invasive or open. The prognosis following Lisfranc injury is determined by the severity of damage and the quality of reconstruction.
UNASSIGNED: Lisfranc-Gelenk-Verletzungen sind seltene, aber schwere Verletzungen des Fußes, die von Bandzerrungen bis zu komplexen Luxationsfrakturen reichen. Ätiologisch werden direkte und indirekte Gewalteinwirkung sowie Hoch- und Niedrigenergietrauma unterschieden. Eine inadäquate Diagnostik (Übersehen oder Fehlinterpretation von Verletzungen) kann zu schmerzhaften posttraumatischen Arthrosen, chronischen Instabilitäten und Fehlstellung des Fußskeletts führen. Ein Fraktur- oder Fehlstellungsnachweis und ein unklarer Befund in der konventionellen Röntgendiagnostik erfordern eine CT einschließlich 3D-Rekonstruktionen. Häufig finden sich pathologische Begleiterscheinungen des Fußes, die ebenfalls adressiert werden müssen. Ausschließlich stabile undislozierte Frakturen können konservativ behandelt werden. Die operative Therapie erfolgt je nach Verletzungsmuster geschlossen perkutan bzw. minimalinvasiv oder offen. Verletzungsschwere und Rekonstruktionsergebnis bestimmen die Prognose.
