Step-cut osteotomy of the anterior superior iliac spine for increased visualisation in the Levine approach for Bernese periacetabular osteotomy surgery.

BACKGROUND: Hip dysplasia can lead to pain and dysfunction in the young adult. Acetabular undercoverage leads to abnormal joint loading and results in joint degeneration, accelerating need for arthroplasty in this patient population. Conceptually, treatment focuses on increasing acetabular coverage in the form of periacetabular osteotomy. The procedure can be performed through the iliofemoral approach, and performing an anterior superior iliac spine (ASIS) osteotomy can enhance the visualisation in this approach. Several techniques have been described for ASIS osteotomy. AIM: The purpose this study was to report on step-cut technique for ASIS osteotomy during the Bernese periacetabular osteotomy procedure to enhance visualisation when utilising the iliofemoral approach. SURGICAL TECHNIQUE: This step-cut technique enhances stability at the osteotomy site, and minimises soft tissue dissection to reduce pain and assists with maintaining a stable fixation construct postoperatively. RESULTS: There were no nonunions and minimal morbidity to the lateral femoral cutaneous nerve injury in cohort of 86 patients while utilising this technique. CONCLUSIONS: We recommend using this step-cut ostetomy of the ASIS during Bernese periactetabular osteotomy for benefit of increasing exposure while maintaining a low complication profile.

Surgical exposure and fixation of displaced type IV, V, and VI glenoid fractures.

Displaced intra-articular fractures of the glenoid are rare and frequently result from high-energy injuries. Types IV, V, and VI fractures have in common a fracture line which extends medially into the scapular body. These fracture patterns present unique challenges for surgical approaches and reduction and fixation strategies. A modified posterior approach allows for the simultaneous exposure of the medial scapular border and the glenoid articular surface. An initial reduction of the medial fracture indirectly restores the scapular relationship, allowing for subsequent completion of the articular reduction via a limited approach to the posterior shoulder using the same incision.

Multisegmental open sacral fracture due to impalement: a case report.

We report on an unusual impalement injury to the sacrum in a 15-year-old adolescent patient. This open pelvic fracture resulted in a shattered sacrum with neurologic impairment including clinically absent anal sphincter tone and perineal sensation. Early debridement, wound revision, neural decompression, fracture reduction, and stable fixation using lumbopelvic fixation according to the principles of triangular osteosynthesis resulted in a favorable outcome with primary wound healing, return of bowel and bladder control, as well as immediate patient mobilization.

Nonunion treatment: iliac crest bone graft techniques.

In the management of nonunions, detailed surgical treatment plans will vary depending on the underlying etiology of the specific case. Iliac crest autogenous bone grafting, although associated with donor site complications, continues to be a necessary part of the treatment of many nonunions. This article summarizes the classification of nonunions and the use of iliac crest autogenous bone grafting, the standard against which any new technique must be measured.

Nonunion of femoral neck fracture and trochanteric osteotomy after a pinned, slipped capital femoral epiphysis: a case report.

Femoral neck fracture as a complication of slipped capital femoral epiphysis (SCFE) is rare. Even rarer is a femoral neck nonunion as an additional complication. This is the first case reported in the literature of a failed valgus osteotomy for a femoral neck nonunion. A salvage operation involving a step-cut valgus/flexion/internal rotation osteotomy, open reduction and internal fixation, with a blade plate and cannulated screw, placement of an allograft femoral strut, and allograft bone grafting was successfully performed. Femoral neck fractures following SCFE fixation are more difficult to treat because of abnormal femoral neck configuration. Therefore a valgus, flexion, and internal rotation producing osteotomy may need to be initially performed to prevent a femoral neck nonunion.
