Wellbore Cooling Effect during Dual-Wall Drill Pipe Drilling of Ultra-Deep Horizontal Well

Shiyou jixie
Excessive bottom-hole temperature occurs during ultra-deep horizontal well drilling. In this study， a transient wellbore heat-transfer model for dual-wall drill pipe drilling was established considering the multi-channel heat transfer of the dual-wall ...

A Modified Anatomical All‐Inside Double‐Bundle Anterior Cruciate Ligament Reconstruction Technique

Arthroscopy Techniques, EarlyView.
Abstract Arthroscopic anterior cruciate ligament (ACL) reconstruction (ACLR) is the standard surgical treatment for ACL injuries and is most commonly performed using anatomical single‐bundle (SB) or double‐bundle (DB) techniques. With the development of the all‐inside technique, the all‐inside SB technique using socket‐based tunnels and cortical ...

Avoiding Femoral Tunnel Convergence and Graft Damage While Performing Anterior Cruciate Ligament Reconstruction With Lateral Extra‐articular Tenodesis

Arthroscopy Techniques, EarlyView.
Abstract Lateral extra‐articular tenodesis (LET) procedures have become increasingly popular in recent years as adjuncts to anterior cruciate ligament (ACL) reconstruction. One potential complication of combining LET with ACL reconstruction is tunnel convergence, which can lead to inadvertent loss of femoral ACL graft fixation.

Open Latarjet Procedure Using Double Suture‐Button Fixation

Arthroscopy Techniques, EarlyView.
Abstract The Latarjet procedure is the most commonly used technique for recurrent anterior instability with significant bone loss. However, the screws used to fix the coracoid are the major risk for postoperative complications including screw penetration and glenoid articular cartilage damage, prominence and impingement of the screw head onto the ...

Combined Anterior Cruciate Ligament Reconstruction and Extra‐articular Tenodesis Using the Iliotibial Band With Femoral Press‐Fit Fixation: A Low‐Cost and Reproducible Technique

Arthroscopy Techniques, EarlyView.
Abstract The addition of a lateral extra‐articular reinforcement to anterior cruciate ligament reconstruction has been shown to enhance rotational stability and protect the intra‐articular graft. Although several techniques using the iliotibial band have been described, most rely on fixation devices that increase surgical cost and complexity.

Open Multiligament Reconstruction for Concomitant Patellofemoral and Type IV Tibiofemoral Dislocation and Bucket‐Handle Medial Meniscus Injury

Arthroscopy Techniques, EarlyView.
Abstract A knee dislocation combined with a patellofemoral dislocation is an extremely rare and complex injury that reflects severe multidirectional instability and extensive soft‐tissue disruption. We show an open single‐stage anatomic reconstruction method for a patient with type IV tibiofemoral dislocation, patellofemoral dislocation, and bucket ...
