We report two older patients with PSI complicated by massive retroperitoneal and gluteal abscesses, highlighting the importance of early recognition and, when indicated, timely surgical source control. Case 1 was an 83-year-old woman in whom a conspicuous retroperitoneal abscess and abnormal urinalysis led to suspicion of an intra-abdominal or urinary tract source, delaying recognition of PSI. Despite antibiotics, she deteriorated with organ dysfunction; re-evaluation of the initial magnetic resonance imaging MRI identified the sacroiliac joint as the primary focus, and staged surgical drainage procedures were required, followed by a prolonged recovery. Case 2 was a 70-year-old woman who presented in septic shock after failing outpatient treatment for presumed lumbar spine disease. Based on the diagnostic pitfalls in Case 1, PSI was immediately suspected; emergency drainage of both retroperitoneal and gluteal collections was performed on the day of presentation, which was followed by rapid stabilization and recovery. These cases emphasize that, in older patients with low back or gluteal pain, the concurrent presence of retroperitoneal and gluteal abscesses should prompt careful evaluation of the sacroiliac joint. These observations suggest that early diagnosis and timely assessment for surgical source control may contribute to favorable outcomes in severe cases.","PeriodicalId":30287,"journal":{"name":"Case Reports in Orthopedics","volume":"2026 ","pages":"5538167"},"PeriodicalIF":0.4,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13676302/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149215710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients generally report lower abdominal or groin pain, and they may demonstrate signs of hemodynamic instability. Prompt recognition of retroperitoneal hemorrhages requires a thorough history and physical examination, monitoring of appropriate laboratory values, and often advanced imaging. Whereas treatment can occasionally be achieved with conservative measures, retroperitoneal hemorrhage is most commonly treated with embolization. We present a case of spontaneous retroperitoneal hemorrhage after percutaneous L3 to pelvis posterior spinal instrumentation and L4-L5 posterolateral fusion with allograft. In our case, the patient was noted to be hypotensive and began reporting right lower quadrant abdominal pain on postoperative Day 2. Investigation with computed tomography angiography revealed a right retroperitoneal hematoma with small areas of active bleeding, ultimately requiring an embolization procedure with interventional radiology. The patient was last seen for a 1-year follow-up, at which time he demonstrated 5/5 motor strength and fully intact sensation throughout L2-S1 of the bilateral lower extremities. He complained of mild right lumbar pain over the region of hardware after recently losing approximately 30 pounds and recent balance issues. This case highlights common presenting signs/symptoms of a relatively uncommon and potentially fatal complication in the setting of percutaneous spinal surgery; we hope to increase awareness and improve prompt recognition among providers to help minimize serious complications for patients.","PeriodicalId":30287,"journal":{"name":"Case Reports in Orthopedics","volume":"2026 ","pages":"2550320"},"PeriodicalIF":0.4,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13662823/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149196897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Delayed recognition or inadequate management may lead to atrophy of the anterior and lateral compartment muscles and persistent disability.Case presentation: We report a 72-year-old woman who developed an acute, complete CPNP with foot drop and dorsal foot sensory loss on the first day after primary right TKA. Management was nonoperative and centred on early limb repositioning, ankle-foot orthosis (AFO) support and a structured physiotherapy programme that included neuromuscular electrical (faradic) stimulation. Full neurological recovery was achieved 115 days after surgery, with normal muscle power and no residual sensory deficit.Conclusion: Complete CPNP after TKA carries a less favourable prognosis than incomplete palsy, yet this patient regained full function within approximately 4 months of conservative care underscoring that, in the absence of a compressive lesion or progressive deficit, early nonoperative management with orthotic support and physiotherapy can achieve excellent recovery and that surgical exploration can reasonably be reserved for deterioration or failure to improve.","PeriodicalId":30287,"journal":{"name":"Case Reports in Orthopedics","volume":"2026 ","pages":"9751384"},"PeriodicalIF":0.4,"publicationDate":"2026-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13643216/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149137756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although vascular injuries have been described in the literature, proximal arterial occlusion at the level of the external iliac artery after a primary posterior total hip arthroplasty, to our knowledge, has not been previously reported. We present the case of a 74-year-old woman who developed acute limb ischemia approximately 3 h after undergoing an primary posterior total hip arthroplasty without any intraoperative complications. On postoperative examination, she was noted to have diminished distal perfusion of the operative extremity. Upon return to the operating room, angiography revealed an acute occlusion of the external iliac artery. The patient underwent emergent thromboembolectomy, which successfully restored arterial flow. No underlying vascular disease or hypercoagulable condition was identified on further evaluation, and a positional or compression-related mechanism was hypothesized as the most likely mechanism. This case highlights an underrecognized but serious complication that may occur even in routine total hip arthroplasty. It underscores the importance of meticulous intraoperative positioning, heightened awareness of potential vascular compromise, and routine postoperative neurovascular assessment. Early recognition of ischemic signs and prompt surgical intervention are critical to preventing irreversible limb damage and optimizing patient outcomes.","PeriodicalId":30287,"journal":{"name":"Case Reports in Orthopedics","volume":"2026 ","pages":"7440156"},"PeriodicalIF":0.4,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13636141/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149115581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report a 31-year-old male who sustained a Gustilo-Anderson grade IIIB open fracture of the radius and ulna following a high-energy dirt bike injury, complicated by Serratia marcescens fracture-related infection and septic nonunion. Intraoperative debridement at Stage 1 revealed a 6-cm defect of the ulna, which was managed with an antibiotic-impregnated polymethylmethacrylate (PMMA) spacer. A concomitant radial nonunion, identified on postdebridement CT, was addressed at Stage 2 with concurrent revision open reduction and internal fixation (ORIF) and autogenous femoral bone grafting. Culture-directed oral antibiotic therapy was administered following Stage 1. Mature bridging callus was noted at 6 months and confirmed at both bones at approximately 22 months postinjury, with infection eradication confirmed at Stage 2. Prior to subsequent elbow procedures, the patient demonstrated a Mayo Elbow Performance Score of 65 (fair), with an elbow arc of motion of 60°-140° and forearm rotation of 70° pronation and 75° supination. This case illustrates the utility of IMT for ulnar reconstruction in the setting of fracture-related infection, and highlights a forearm-specific biomechanical consideration: Fixing the ulna at a set length via the IMT spacer construct while shortening the radius for nonunion compression may alter radioulnar variance, a single-case observation that we hypothesize could have implications for DRUJ and elbow mechanics and warrants further study.","PeriodicalId":30287,"journal":{"name":"Case Reports in Orthopedics","volume":"2026 ","pages":"3342262"},"PeriodicalIF":0.4,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13628570/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149115643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conservative treatments such as medication, physical therapy, and splinting, as well as surgical procedures like synovectomy and debridement, may occasionally help; however, arthrodesis and PIPJ arthroplasty are the definitive surgical options. The goal of replacement arthroplasty is to relieve pain, restore movement, and maintain the stability of the affected joint. Designing an effective replacement arthroplasty requires a deep understanding of current biomaterials and an appreciation for the complex biomechanics of the PIP joint. The use of local anesthetic (wide-awake local anesthesia no tourniquet [WALANT]) offers advantages such as the absence of discomfort from a tourniquet, reduced personnel and sedation costs, faster recovery, and intraoperative assessment of motor function.

Most evidence derives from case series in elderly patients, and reports detailing progressive soft tissue release strategies in young active individuals remain scarce.Case presentation: A 25-year-old male kitesurfer presented with an 8-month history of NASD following unsuccessful open reduction and internal fixation for a proximal humeral fracture-dislocation. The patient had marked limitation in range of motion and visible deformity, without axillary nerve dysfunction, with imaging findings of 30% glenoid bone loss. Surgical management consisted of progressive soft tissue release and controlled open reduction, including coracoid osteotomy, upper two-thirds subscapularis tenotomy, supraspinatus release, and posterior capsulotomy, followed by a conventional Latarjet procedure. At 24-month follow-up, the patient demonstrated significant improvement in range of motion, patient-reported outcomes (Constant 92, ASES 95), complete pain relief, maintained joint stability, and partial return to recreational kitesurfing, without complications.Conclusions: A structured approach based on progressive soft tissue release combined with stepwise open reduction is essential to safely restore joint congruency in NASD.

Although typically isolated, a split-level bilaminar rupture pattern, in which different layers of the PTR at different anatomical levels, is extremely rare in adults, particularly when associated with complex multiligamentous injuries (occurring in only 0.02%-0.2% of orthopedic cases).Case presentation: A 60-year-old female presented with acute knee pain and loss of active extension following a fall. Clinical examination revealed patella alta and a palpable infrapatellar gap. Imaging confirmed a full-thickness PTR, a medial femoral condyle avulsion fracture (MCL attachment), and a fibular head fracture (PLC injury-variant). Intraoperatively, a split-level bilaminar PTR and a complete midsubstance ACL (anterior cruciate ligament) rupture were identified. The injury was managed through primary repair augmented with a peroneus longus tendon (PLT) autograft to provide early mechanical stability and protect secondary stabilizers during healing.Discussion: A split-level bilaminar PTR in adults with concomitant multiligamentous injury is a rare clinical entity that requires high diagnostic suspicion. In this case, PLT augmentation provided a robust construct for extensor mechanism reconstruction while preserving the hamstring tendons and allowing good functional outcomes.Conclusion: In this case, anatomical repair augmented with a peroneus longus autograft resulted in restoration of the extensor mechanism at the 6-month postoperative follow-up while preserving the hamstring tendons.","PeriodicalId":30287,"journal":{"name":"Case Reports in Orthopedics","volume":"2026 ","pages":"5640221"},"PeriodicalIF":0.4,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13627862/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149115698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
