CASE A 69-year-old woman presented with a brachial artery pseudoaneurysm causing median, ulnar, and radial nerve compressive neuropathies 8 weeks after a proximal humerus shaft fracture treated with intramedullary nailing. She underwent a brachial artery bypass with a reverse cephalic vein interposition graft and neurolysis after decompression of a large pseudoaneurysm. Postoperatively, the patient had a normal vascular examination with recovering neurological function. CONCLUSIONS A high index of suspicion for a brachial artery pseudoaneurysm should be maintained in patients with a displaced proximal humerus shaft fracture, particularly when an abnormal neurovascular examination is present.CASE A 78-year-old women presented with a closed left midshaft femur fracture after sustaining a fall from standing height and underwent proximal tibial traction pin placement. After subsequent intramedullary nailing of femur fracture, the patient returned 2 months later with a proximal tibia fracture through the unicortical defect left from the traction pin site and underwent successful intramedullary nailing of the tibia. CONCLUSION Errant anteriorly placed proximal tibial traction pins pass tangentially across the vertex of the tibia and create residual unicortical defects that may increase the risk for late iatrogenic pin site fractures.CASE We present the case of a 71-year-old man with right knee osteoarthritis (OA) and a varus deformity who developed a progressive common peroneal nerve palsy that resolved after total knee arthroplasty (TKA). After decades of knee pain, the patient gradually developed a foot drop as well as numbness and paresthesias over the foot dorsum during the course of 1 month. The patient underwent TKA and within 6 weeks postoperatively had complete resolution of the peroneal nerve symptoms. CONCLUSION A progressive common peroneal palsy in advanced varus knee OA may resolve after a properly aligned TKA without nerve decompression.CASE A 17-year-old boy had persistent knee pain 1 year after medial meniscal root repair augmented with bone marrow aspirate concentrate injection. Radiographs and magnetic resonance imaging (MRI) demonstrated an intrameniscal ossicle which was not present on MRI performed before 6 months. He underwent arthroscopic excision of the meniscal ossicle. At the 7-month follow-up, he had complete relief of his pain. CONCLUSIONS It is possible that the meniscal ossicle developed because of osteoinductive cells and cytokines from the injected bone marrow or the drill hole for root repair and should be considered as a possible complication of this procedure.CASE A 33-year-old man with recurrent intrathoracic scapular dislocation due to previous trauma-related chest wall resection successfully underwent the 2-stage induced membrane technique commonly known as the Masquelet technique; this procedure effectively created 2 new ribs that resolved his symptoms. CONCLUSIONS Techniques for chest wall reconstruction for bone loss are quite limited, and these often consist of filling defects with a layered patch; this often cannot withstand the cyclical respiratory motion. EPZ005687 ic50 Use of the induced membrane technique appears to carry potential when used in the chest wall, and this report describes a technique by which this procedure can be reliably performed.CASE A 38-year-old woman presented with previously undiagnosed factor V Leiden (FVL), who suffered a complete superficial femoral arterial thrombosis after tourniquet use during the surgical repair of one of her bilateral tibial plafond fractures. This patient's injury eventually resulted in a below-knee amputation. CONCLUSION We recommend expanding hypercoagulable screening on patients with risk factors based on a detailed history and physical examination. We also recommend limiting or negating tourniquet use in patients with FVL or other hypercoagulable disorders.CASE We present a case of a pediatric patient who sustained a medial humeral epicondyle fracture with avulsion of the ulnar collateral ligament and flexor-pronator mass from the ossific nucleus fracture fragment. Treatment included excision of the medial epicondyle ossific nucleus and repair of the soft tissues. At 1-year, the patient had no pain, no elbow instability, and full and symmetric elbow range of motion. CONCLUSION Excellent short-term pain and function outcomes can be observed in the pediatric patient after medial epicondyle fragment excision when there is concomitant avulsion of the ulnar collateral and flexor-pronator origins from the fracture fragment.CASE A 16-year-old male patient with severe kyphoscoliosis, paraplegia, and neurogenic bowel/bladder caused by a juvenile pilocytic astrocytoma was treated surgically using a hybrid fusion construct with polyethylene bands after neoplasm resection. Owing to the necessity of serial postoperative magnetic resonance imaging studies to evaluate the recurrence of pathology and known effect of metal artifact from spinal instrumentation, preservation of radiographic resolution was critical. CONCLUSION We describe the novel utility of polyethylene bands placed around the ribs as a safe and effective form of hybrid construct for reducing radiographic metal artifact in spinal deformity cases requiring serial imaging.CASE A 60-year-old man presented with left hip pain, and a radiograph showed reduced joint space. During the surgical procedure for a total hip replacement, a proximal femur mass was identified and biopsy was subsequently interpreted as grade 2 chondrosarcoma. A wide resection was needed, but he developed local recurrence after 2 years and was treated with an external hemipelvectomy. CONCLUSIONS Chondrosarcoma does not always present with a classical clinical picture or imaging, and it can be misdiagnosed. Practitioners should be highly suspicious of malignant disease as a cause for hip pain even if there is no direct indication of a neoplasm such as chondrosarcoma.CASE We report the case of an 82-year-old woman with diabetes, arteriosclerosis, chronic heart failure, and hypertension treated with an anatomical locking plate and multiple cables for a spiral-wedged periprosthetic fracture of the distal femur which was complicated by direct occlusion of the femoral artery and crush of the sciatic nerve, resulting in leg necrosis and, ultimately, through-knee disarticulation despite early recognition and arterial repair. CONCLUSIONS Neurovascular injury is a potential complication of cerclage cables placement around the femoral shaft during complex fracture fixation. Devastating complications cannot always be corrected despite early vascular intervention.
