Background: With an incidence of 50% of humerus fractures, proximal humerus fractures (PHFs) can significantly impact one's quality of life. Moreover, management of highly comminuted or displaced PHFs poses a significant challenge amongst elderly population due to poor bone quality. Prosthetic replacement of humeral head or its stabilization using external plates is a commonly employed intervention for treating three-and four-part PHFs. Thus, these two methods were compared in this study to identify a preferable intervention.Methods: Patients were randomly divided into two groups to receive proximal humerus internal locking system (PHILOS®, Synthes, Switzerland) plating and Neer's hemiarthroplasty. The deltopectoral approach was deployed as the surgical method. Their surgical outcome was assessed from functional range of motion (ROM) and Constant-Murley scores at regular intervals of three, six, twelve, and twenty-four weeks.Results: Twenty patients were divided into two groups who received PHILOS ® plating and Neer's hemiarthroplasty, averaged 67.2 years and 72.8 years. The ROM pertaining to flexion, extension, abduction, internal rotation, and external rotation for individuals with PHILOS ® plating was 20%, 12.5%, 14.7%, 11.5%, and 18.5% higher than those who received Neer's hemiarthroplasty. Moreover, the Murley score was also 8.7 units higher for individuals with PHILOS ® plating.Conclusions: Prognosis following PHILOS® plate osteosynthesis had a better overall outcome than hemiarthroplasty with Neer's prosthesis. Although hemiarthroplasty yielded a consistent functional outcome, PHILOS® plate osteosynthesis tends to restore a greater ROM. Thus, PHILOS® plating is recommended as the suitable method to manage three-and four-part PHF for people above fifty-five years of age.

Epidural anaesthesia (EA) has consistently been used for treatments affecting the pelvis, lower limbs, lower abdomen, and perineum; however, it is progressively employed as a single anaesthetic or supplement to general and spinal anaesthesia for a broader range of procedures. The retention of a broken epidural catheter piece is an uncommon but well-known complication. In this report, we present a 30-year-old male with avascular necrosis (AVN) of the hip who was referred for total hip replacement (THR). An epidural catheter had been placed at the presumed L2-3 interspace to administer EA. The catheter had been set too deep and it broke on extraction with the Tuohy needle, leaving a fragment inside. The patient was then given general anaesthesia and the planned procedure of THR was done in the lateral position. The patient was then shifted to the prone position to remove the retained fragment of the epidural catheter by a minimally invasive spinal surgery (MISS). Right-sided L2 laminotomy was done, as the epidural catheter was inserted from the right side, to retrieve the broken fragment without any added postoperative neurological complications. MISS may be attempted by experienced surgeons for the removal of a retained fragment of the epidural catheter from the spinal canal before adhesion as a safe option.

The constellation of signs, symptoms, and radiographic features was characteristic of emphysematous septic arthritis. The patient recovered well following surgery and treatment with antibiotics. To our knowledge, this is the first reported case of such arthritis caused by C. freundii.
