Acetabular fixation is better to be performed in a second stage after the hyper-inflammation phase ends. The definitive management for the contralateral floating knee can be delayed to a third stage but should be completed within the 10-day limit of immunosuppression.
 The acute management of ipsilateral femoral shaft and neck fractures in such cases has to be prioritized. The use of a retrograde nail in addition to dynamic hip screw (DHS) with two cannulated anti-rotation screws and locking the DHS to the nail is likely to increase the healing potential of femoral neck fracture in these cases. Acetabular fixation is better to be performed in a second stage after the hyper-inflammation phase ends. The definitive management for the contralateral floating knee can be delayed to a third stage but should be completed within the 10-day limit of immunosuppression.
  Degeneration of the fibrocartilaginous acromioclavicular (AC) joint disk can become significant in later life and lead to primary osteoarthritis and shoulder pain. Younger, non-arthritic individuals may develop residual shoulder symptoms due to tearing of the disk itself.
 
  Six patients (seven shoulders) were included in this case series. They were athletic and between the ages of 17 and 22. They typically presented with lingering symptoms of pain, popping, and instability in and around the AC joint after prior trauma or injury involving their shoulder. For most, symptoms lasted longer than 2 months before they sought additional treatment. Plain films were negative, and magnetic resonance imaging occasionally demonstrated pathology at the AC joint. Conservative treatment provided limited relief. All patients included in this series underwent arthroscopic distal clavicle resection. Intraoperatively, the disk could be seen as acutely torn or degenerative in all cases. In some, it was hypermobile and could be manually subluxed in and out of the joint.
 
  A torn AC joint disk may cause lingering symptoms in young patients without radiographic evidence of arthritis. Further study is needed to determine if these findings are truly causative or merely incidental.

  Stress fractures are overuse injuries resulting from repetitive submaximal loading of a bone. Acetabular stress fractures while highly uncommon can occur in those undergoing intense endurance training as is the case with military recruits. Diagnosis of this injury can be dubious at times, with magnetic resonance imaging (MRI) being the most sensitive diagnostic tool considering the lower sensitivity of plain film radiography.
 
  The authors report a case of acetabular stress fracture occurring in a healthy male amateur endurance runner presenting with activity related hip pain that presented acutely without any prodromal pain. Plain film radiography and MRI revealed a transverse fracture of the acetabulum.
 
  Stress fractures of the acetabulum are among the rarest locations in which stress fractures can occur. They typically occur in individuals undergoing intense endurance training and require a high degree of suspicion to diagnose. The patient presented within represents a unique presentation not previously described.

  Factor XI (FXI) deficiency is a hematologic condition that is rarely encountered by the arthroplasty surgeon. Effective risk assessment and perioperative management are paramount in minimizing the risk of intra- and post-operative bleeding in this patient population. An interdisciplinary approach is crucial in minimizing complications and achieving successful outcomes. We present the case of a patient that successfully underwent conversion total hip arthroplasty (THA) following failed internal fixation of a proximal femur fracture.
 
  A 71-year-old man with a history of FXI deficiency presented with significant right-sided hip pain secondary to post-traumatic arthritis from a previously treated right proximal femur fracture. The patient underwent removal of the cephalomedullary nail and conversion to a THA. Before the procedure, a comprehensive perioperative plan was enacted to manage the patient's FXI deficiency. The patient underwent several infusions of aminocaproic acid and tranexamic acid (TXA) in an effort to prevent intra- and post-operative bleeding. The surgery was completed with excellent hemostasis and no post-operative complications.
 
  Patients with FXI deficiency can successfully undergo conversion THA surgery; however, an individualized hematologic plan must be enacted to minimize complications and maximize surgical outcomes and patient satisfaction. This case demonstrates that the antifibrinolytic agents, aminocaproic acid and TXA, can be successfully used for hematologic prophylaxis in the perioperative period for this population of patients.

  Scapholunate dissociation and ulnar impaction syndrome are common causes of wrist pain but often missed on initial clinical and radiological evaluation; hence, diagnosis is delayed. Management is challenging as there is diversity in surgical option. There is not a single case in literature described for both scapholunate dissociation and ulnar impaction syndrome treated in one setting.  https://www.selleckchem.com/products/Eloxatin.html  We are presenting a case of both ulnar impaction syndrome and scapholunate dissociation treated surgically in one setting with good functional outcome.
 
  A 30-year-old male with chronic scapholunate dissociation and ulnar impaction syndrome treated with modified Brunelli technique for scapholunate dissociation and extra-articular ulnar shortening osteotomy for ulnar impaction syndrome in one setting with good functional outcome.
 
  In cases with scapholunate dissociation and ulnar impaction syndrome, treatment should be directed toward both. When done with careful pre-operative evaluation and planning in one setting, can yield favorable results.
