propose a surgical approach for an oblique fracture of the proximal scaphoid that used guide wires and screws, but was performed through a dorsal, and not palmar, approach to insert the screws in the distal-to-proximal direction.We presume that coronal shear stress to the scaphoid bone occurred when the palm contacted the ball with the wrist positioned at 30° dorsiflexion and 20° ulnar deviation.
  Melorheostosis is a rare condition affecting the bones and has only been occasionally reported. We herein report a case of melorheostosis affecting left femur and tibia which was diagnosed based on clinical and radiological features and managed with bisphosphonates.
 
  A 28-year-old female patient presented with complaints of pain over left knee and thigh for the past 3 months. To evaluate the cause of pain X-ray and magnetic resonance imaging were done, which revealed characteristic candle dripping wax appearance suggestive of melorheostosis. After arriving at the diagnosis patient was started on nonsteroidal anti-inflammatory drugs and pamidronate which provided symptomatic betterment patient has now been followed up for past 1 year and is symptom free.
 
  Melorheostosis is an uncommon cause of a common symptom. Positive clinical and imaging features helped us to arrive at the diagnosis. Proper work up would help in early diagnosis and management. More evidence is needed to illustrate the effectiveness of medical or surgical treatments for patients with this rare diagnosis.

  Bipolar hemiarthroplasty has been reliable and successful treatment for geriatric patients following neck of femur fractures. Dissociation/disassembly of bipolar prosthesis is a rare complication in which separation of outer head from inner head leads to failure of prosthesis and needs revision surgery. The disassembly though commonly seen after years of primary surgery as a result of polyethylene wear leading to fixed varus position of outer head but it can happen in an acute setting anytime in immediate or late post-operative period following posterior dislocation with closed reduction attempt. We describe a rare case of disassembly of monoblock (non-modular) bipolar prosthesis following attempt of closed reduction for posterior dislocation of the prosthesis.
 
  The patient was a 70-year-old male with 3 weeks prior bipolar hemiarthroplasty of hip joint, presented with posterior dislocation. While manipulation during closed reduction maneuvers, the outer head got locked behind acetabulum and component dissoto its characteristic locking mechanism. It is vital to look for proper orientation and stability of components, integrity of abductor mechanism and short external rotators, and restoration of horizontal and vertical offsets during revision.
  Performing total hip arthroplasty (THA) for femoral neck fracture in the setting of a pre-existing intramedullary nail can be technically challenging, particularly if nail extraction is not feasible.
 
  A 76-year-old male presented with a with a displaced femoral neck fracture in the setting of a previously placed antegrade intramedullary nail with a healed femoral shaft fracture. After failed nail extraction, a novel technique was used to remove the proximal portion of the nail to allow for hybrid THA with implantation of a cemented femoral stem.
 
  This is the first reported surgical technique of using a cortical window technique for partial intramedullary nail resection and cemented stem implantation in the setting of challenging intramedullary femoral nail extraction.

  Proximal femur fractures non-union with implant failure creates a nightmare for both the surgeon and the patient. Meticulous surgical planning and the correct choice of the implant are essential to achieve success in the revision surgery.
 
  Eleven patients with ununited proximal femur fractures including both intertrochanteric and subtrochanteric fractures who had a failed previous implant were included in the study. Femoral neck nonunions and infected nonunions were excluded from the study.  https://www.selleckchem.com/products/peg300.html  One patient was lost to follow-up.
 
  One patient was lost to follow-up and out of the remaining ten patients, six were males and four were females. Mean age was 62.2 years (35-74). Union was achieved with mean union time of 10.1 months (9-14). Mean surgical time was 105 min (90-125) and mean blood loss during surgery was 600 ml (350-850). Mean time of revision surgery after the primary index surgery was 20 months (15-30). Mean duration of follow-up was 12.9 months (12-16).
 
  Revision osteosynthesis in proximal femoral nonunions with implant failure is a real test of surgeons expertise because of the many factors going against like osteoporosis, distorted proximal femur anatomy due to the already present implant resulting in poor bone stock availability. Judicious and appropriate selection of implants is an impeccable factor for fracture union and positive outcome.

  Proximal humerus fractures in the pediatric population are relatively uncommon accounting for <3% of all the fractures. Being the growing end of the bone, these fractures have a high threshold for conservative management. Dilemma does exist when such a fracture occurs in a borderline adolescent age group. Occurrence of bilateral physeal fractures in the same anatomical location is exceedingly rare and such a case of bilateral traumatic physeal fracture of proximal humerus has not been reported in the literature.
 
  A 14-year-old male child presented with post-traumatic pain and swelling of both the shoulders. Radiographs revealed displaced proximal humerus physeal fracture bilaterally. The displaced fracture was treated with closed reduction and percutaneous fixation using smooth Kirschner wires and cannulated screw.
 
  Considering the bilateral nature of the injury and a borderline age with limited remodeling potential, a lower threshold for conservative therapy must be adopted in young active individuals.
