OBJECTIVES We investigated the biomechanical characteristics of anterior or posterior tibial tunnel placement of the soft tissue graft with a soft tissue interference screw in anterior cruciate ligament (ACL) reconstruction. METHODS Twelve bovine tibiae and digital extensor tendons were divided into two homogeneously equal groups after they were stripped of all soft tissues. Tibial tunnels we...

PURPOSE To assess the maximum and end torque of a fourth-generation composite humerus model with no screw inserted or with a screw inserted in the distal (subpectoral) position or proximal (suprapectoral) position. METHODS 24 large-size, fourth-generation composite humeri were randomised to the control (n=8), proximal (n=8), or distal (n=8) group. For the latter 2 groups, an 8-mm-head interfe...

BACKGROUND Ligament reconstruction is a common procedure in orthopedic surgery. Although several popular techniques are currently in use, new methods are proposed for secure fixation of the tendon graft into the bone tunnel. PURPOSES We sought to introduce our new technique of Bashti bone plug for fixation of soft tissue graft in anterior cruciate ligament (ACL) reconstruction and to compare ...

Tendon transfers pptay an important role in reconstructive foot and ankle surgery. Multiple methods for fixation of tendon to bone are used including suture of tendon to periosteum, suture into bone troughs, suture anchors, and passage through bone tunnels. With the increasing populatity of hamstring tendon anterior cruciate ligament reconstructions has come new fixation technology. Soft-tissue...

Biceps tenodesis maintains the cosmetic appearance and length-tension relationship of the biceps with an associated predictable clinical outcome compared with tenotomy. Arthroscopic suprapectoral techniques are being developed to avoid the disadvantages of the open subpectoral approach. This study biomechanically compared 3 arthroscopic suprapectoral biceps tenodesis techniques performed with a...

Small rotor clearances are today a vital prerequisite for an efficient screw compressor. The clearances are responsible for compressor leakages, small clearance will minimise them and thereby increase both, the volumetric and adiabatic efficiency. A continuous improvement in the rotor manufacturing equipment has been achieved during the recent years and tight production tolerances may now be ap...

PURPOSE We evaluated the initial bone-patellar tendon-bone (BPTB) graft fixation strength of biodegradable pins compared with interference screws in anterior cruciate ligament reconstruction using bovine knees. TYPE OF STUDY Biomechanical in vitro study. METHODS Ten BPTB grafts from human donors fixed with 2 biodegradable 2.7-mm pins (Rigid Fix; Ethicon, Mitek Division, Norderstedt, Germany...

PURPOSE The purpose of this study was to evaluate the effect of hybrid femoral fixation with bioabsorbable interference screws (BioRCI; Smith & Nephew Endoscopy, Andover, MA) and EndoButton CL (Smith & Nephew Endoscopy) fixation. METHODS Biomechanical testing of 3 different fixation techniques was performed by use of porcine hind-limb distal femurs and mature bovine extremity common extensor ...

This study compared the stiffness (K), yield load (YL), and slippage (SL) of six tibial fixation methods. These properties were determined from load-to-failure and cyclic tests of double-looped tendon grafts fixed to both animal and young human tissue. Tandem washers (K = 259 N/mm, YL = 1159 N, SL = 0.5 mm) and the Washerloc (K = 248 N/mm, YL = 905 N, SL = 2.0 mm) were the two best fixations. A...

BACKGROUND Tenodesis of the long head of the biceps tendon is a common procedure used to alleviate pain caused by instability or inflammation of the tendon. The purpose of this study is to report on the incidence and types of complications following an open subpectoral biceps tenodesis (OBT) procedure. HYPOTHESIS Our hypothesis was that the rate of adverse events after OBT was low. METHODS ...
