Outcomes of Headed and Headless Cannulated Screws Fixation in Nondisplaced Femoral Neck Fracture [PDF]

Geriatric Orthopaedic Surgery & Rehabilitation
Background The incidence of femoral neck fracture is increasing as society ages. Different types of cannulated screws can be used for internal fixation of femoral neck fractures, but no screw selection protocol has been determined to reduce the risk of ...

Evaluation of Cannulated Compression Headless Screw (CCHS) as an alternative implant in comparison to standard S1-S2 screw fixation of the posterior pelvis ring: a biomechanical study [PDF]

BMC Musculoskeletal Disorders, 2023
Background/Purpose Posterior pelvis ring injuries represent typical high-energy trauma injuries in young adults. Joint stabilization with two cannulated sacroiliac (SI) screws at the level of sacral vertebrae S1 and S2 is a well-established procedure ...

Posterior Arthroscopic Talar Body Nonunion Repair With Subtalar Arthrodesis. [PDF]

Arthrosc Tech
Abstract Talus fractures are a rare and challenging problem for the orthopaedic surgeon. They often present following high‐speed injury mechanisms in patients with polytraumatic injuries. Diagnosis and treatment of these fractures may be delayed, at times leading to talus nonunion or malunion.

A biomechanical comparison of closed-reduction osteosynthesis techniques for fractures of the ulnar styloid [PDF]

Journal of Orthopaedic Surgery and Research
Background Ulnar styloid fractures (USF) are frequently underestimated and can contribute to clinically relevant wrist instability and impaired functional outcomes. Several osteosynthesis techniques are available for the treatment of unstable USF.

Tips and Tricks for Hardware Removal and Allograft Fixation After a Failed Latarjet Procedure. [PDF]

Arthrosc Tech
Abstract Although relatively rare, recurrent anterior shoulder instability requiring revision surgery after a failed Latarjet procedure can result in complications such as graft malposition, graft osteolysis, broken hardware and/or infection. Revision surgery after a failed Latarjet is a challenge due to a combination of technical factors such as ...

Does fully-threaded Headless Compression Screw provide a length-stable fixation in undisplaced femoral neck fractures?

Asian Journal of Surgery, 2019
Summary: Objective: Femoral neck shortening is a common complication after surgical treatment for intracapsular femoral neck fractures. This study investigated whether fully-threaded Headless Compression Screw (FTHCS) can be a more length-stable implant
