Patients with early or metastatic cancer may suffer from pain of different origins. The vast majority of these patients are not adequately treated by means of systemic analgesia and radiotherapy. Percutaneous neurolysis is performed using chemical agents or thermal energy upon sympathetic nervous system plexus for pain reduction and life quality improvement. Ablation and vertebral augmentation are included in clinical guidelines for metastatic disease. As far as the peripheral skeleton is concerned bone augmentation and stabilization can be performed by means of cement injection either solely performed or in combination to cannulated screws or other metallic or peek implants...

BACKGROUND: Tibiotalocalcaneal arthrodesis is most common and effective surgical treatment for severe hindfoot pathology, but the fusion rate is often lower than the ordinary tibiotalar arthrodesis because of the more serious joint disease associated with obvious deformity and osteoporosis. Recent literature describe tibiotalocalcaneal arthrodesis with reverse PHILOS plate with good clinical outcome result, though some patients non-union, due to eccentric force of the plate may be hidden...

BACKGROUND: Pedicle screw fixation of the lumbar spine in children less than two years of age is particularly challenging, as successful cannulation of the small pedicle dimensions require a high level of precision and there are no implants specifically designed for the infantile spine. Image-guided navigation is commonly used in adult spinal surgery and may be particularly helpful for placement of spinal screws where the bony anatomy is small and/or anatomically complex as in the upper cervical area...

PURPOSE: Operative fixation of displaced patella fractures is considered to be standard of care. However, patients with inferior pole patella fractures have limited options in terms of fixation. This video demonstrates the repair of an inferior pole patella fracture using nonabsorbable suture fixation. METHODS: Suture repair of patella fractures is a clinically acceptable technique, yielding similar functional results to patella fractures treated with K-wires or cannulated screws while reducing the rates of removal of hardware after fixation...

Patellar fractures can occur as a result of direct or indirect injuries. Indirect injury is more common and occurs when the patella fails in tension when the force exerted by the extensor mechanism exceeds that of the bone. Common mechanism of indirect injury is rapid knee flexion with fully contracted quadriceps muscle. Treatment with a tension band construct is indicated for transverse patella fractures without significant comminution. This can be performed with 18-gauge wire and either 2 parallel, longitudinally oriented cannulated screws or 2 Kirschner wires...

BACKGROUND: Guided growth using the eight-plate (8-plate) is the most commonly used method to correct angular deformities in children; however, implant failure has been reported. Recently, the 3.5-mm reconstruction plate (R-plate) has been used as an alternative option for guided growth; however, hardware prominence has been problematic. This study aimed to compare the coronal angular deformity correction results of guided growth between relatively thin 8-plates with cannulated screws and thick R-plates with solid screws...

Stabilization of pelvic ring injuries and certain acetabular fractures using percutaneous techniques is becoming increasingly more common. Intramedullary superior ramus screw fixation is beneficial in both injury types. While implants can be placed in an antegrade or retrograde direction, parasymphyseal ramus fractures benefit from retrograde implant insertion. In some patients, the parabolic osseous anatomy or obstructing soft tissues of the anterior pelvis or thigh can prevent appropriate hand and instrumentation positioning for appropriate retrograde ramus screw insertion through the entire osseous fixation pathway...

PURPOSE: Slipped capital femoral epiphysis (SCFE) is a deformity of the proximal femur secondary to widened and unstable physis. In stabilising the slip, gold standard treatments stop growth and involve premature physeal closure, which prevents the remodelling of the acquired deformity and creates a leg length discrepancy that may be significant in younger patients. METHODS: We measured the impact of placing threaded screws across the proximal femoral physis by measuring the centre-trochanteric distance (CTD) and articulo-trochanteric distance (ATD) in participants with or without prophylactic fixation...

STUDY-DESIGN: Case-series. OBJECTIVE: Report our modified iliac-screw insertion technique and its clinical outcomes. SUMMARY OF BACKGROUND DATA: Iliac-screws are one of the preferred methods for modern spinopelvic-fixation. However the technique is not without complications, predominantly due to iliac-screw head prominence, leading to pain and revisions. Conventional iliac-screw entry point is sited superficially at the posterior-superior-iliac-spine (PSIS) contributing to screw-head prominence...
