Summary: It is unclear if extended trochanteric osteotomy (ETO) is effective in the setting of periprosthetic joint infection (PJI). Concerns exist regarding persistent infection with cerclage fixation, but limited evidence supports this theory. The study found no significant differences in operative time, blood loss, rate of repeat revision surgery, or postoperative complications between retaining or exchanging cerclage fixation in PJI patients. ETO remains a powerful tool for femoral component revision even in the presence of PJI.

Summary: This study compared the functional outcomes and mortality rate in patients with periprosthetic hip fractures and femoral stem loosening who were treated with either internal fixation using a locking plate only or a combination of revision with a cemented stem. The results showed no significant difference in functional outcomes between the two treatment strategies. Internal fixation with a locking plate appears to be an acceptable solution for periprosthetic hip fractures with femoral stem loosening.

Summary: There is a debate on whether to perform open reduction and internal fixation (ORIF) or revision arthroplasty (RA) in Vancouver B2 periprosthetic hip fractures. This study aims to establish a decision-making algorithm based on various factors. Relative indications for ORIF include low-medium functional demand, high anaesthetic risk, many comorbidities, 1 zone fractured, anatomical reconstruction possible, and no prior loosening. Relative indications for RA include high functional demand, low anaesthetic risk, few comorbidities, fracture = 2 zones, comminuted fractures, and prior loosening. Cemented stems with intact cement-bone interface, no subsidence, anatomically reducible cement mantle, and partial stem-cement attachment can be treated with ORIF safely.

Summary: This study aimed to analyze and compare the current evidence for the use of open reduction and internal fixation (ORIF) constructs compared with conventional revision total hip arthroplasty (rTHA) for managing Vancouver B2 periprosthetic femoral fractures (PFFs). The results showed that rTHA had a similar revision rate to ORIF in PFFs with a loose femoral component and adequate bone stock. ORIF was superior to rTHA in preventing postoperative dislocation. This review suggests that both ORIF and rTHA may have a potential role in managing Vancouver B2 PFFs.

Summary: This study biomechanically evaluated the effect of a proximal periprosthetic femoral medial wall defect on the stability of a diaphyseal anchored, cementless stem. The results showed that a medial wall defect significantly decreases the axial stability of the stem, but a safe zone remains at loosening rates of about 4 multiples of the body weight.

Summary: Clinical studies suggest that untreated basal ulnar styloid fractures may not affect patient outcomes. In a biomechanical cadaveric model, it was found that some ligament components still remain attached to the ulnar head in the presence of a foveal fracture, providing residual stability to the distal radioulnar joint.

Summary: Chronic traumatic anterior shoulder instability refers to recurrent trauma-associated shoulder instability that requires assessment of three anatomic lesions: a capsuloligamentous and/or labral lesion, anterior glenoid bone loss, and a Hill-Sachs lesion. Surgical treatment is usually necessary, but there is controversy regarding how to evaluate risk factors to determine the appropriate procedure. Patient risk factors for recurrence include age, hyperlaxity, and participation in competitive, contact, and overhead sports. Trauma-related factors include soft tissue lesions and bone loss, which have implications for treatment. Different treatment options are discussed and compared based on complications, return to sports parameters, short- and long-term outcomes, and the risk of osteoarthritis. Arthroscopic Bankart and open Latarjet procedures have a steep learning curve, and the development of osteoarthritis is associated with the number of previous dislocations and surgical techniques. Latarjet-type procedures have the lowest rate of dislocation recurrence and, when performed correctly, do not appear to increase the risk of osteoarthritis.

Summary: Chronic posttraumatic shoulder instability is a trauma-related condition characterized by recurrent dislocations. Surgical treatment, such as arthroscopic Bankart repair (ABR), Latarjet, or alternative procedures, is usually needed. Risk factors including patient age, hyperlaxity, sports profile, and bone loss should be considered when deciding on the surgical approach. ABR provides high patient satisfaction and return to sports, but there is a risk of recurrent dislocations, especially in the presence of risk factors. Latarjet or bone block procedures offer sustainable stability and can be used as a revision procedure, but they can also be used as a primary treatment for chronic instability, depending on the risk factors.
