Arthroscopic Suture Fixation of Os Acetabuli With Absorbable Suture Anchors-A Double-Pulley Technique.

ABSTRACT: Os acetabuli is a bone fragment with unknown origin and isolated at the acetabular rim that may be associated with cam-type femoroacetabular impingement. If this bone fragment is too large and threatens the stability of the hip joint after resection, fixation would be recommended. However, conventional rigid fixation with metal screws has some disadvantages. We describe an arthroscopic suture fixation of the Os acetabulum with absorbable anchors penetrating the bone fragment and secured by tying knots in a double-pulley fashion simultaneously. This technique provides a new feasible solution for the fixation of Os acetabuli, avoiding any metal implants and potential damage to the joint.

Arthroscopic Fixation of Os Acetabuli and Labral Repair: Suture-on-Screw Technique.

Project description:Os acetabuli is thought to be the result of an unfused ossification center or an acetabular rim fracture in the setting of femoral-sided femoroacetabular impingement syndrome. Historically, patients with symptomatic hips have been treated with resection alone; however, in patients with large bone fragments or with reduced acetabular coverage prior to surgical intervention, iatrogenic dysplasia and structural instability may develop after resection. Therefore, for patients with an acetabular os, labral tearing, and cam-type femoroacetabular impingement, internal fixation of the os acetabuli, femoral osteochondroplasty, and labral repair have been described. We propose a "suture-on-screw" arthroscopic technique to simultaneously address both the labral tear and os acetabuli, thereby reducing the number of suture anchors required for labral fixation, leading to an efficient and cost-effective approach for the treatment of these patients.

Screw Fixation of Os Acetabuli: An Arthroscopic Technique.

Project description:An os acetabuli (OA) increases the contact area and surface area of the acetabulum and is important to maintain congruity of the hip joint. Thus preservation of this ossicle is important to prevent loss of contact area and ensure containment of the femoral head. We describe an all-arthroscopic approach to the fixation of OA with a compression screw. Initially, the fibrous tissue is debrided between the acetabular rim and the OA, a guidewire is placed through the OA up to the acetabular rim, and a screw is inserted over the wire. Compression of the OA is achieved with bone-to-bone contact. This technique prevents loss of femoral head coverage, reducing the risk of subluxation and subsequent osteoarthritis.

Suture-on-Screw Technique for Os Acetabuli Fixation and Labral Repair.

Project description:The os acetabuli is thought to arise from unfused secondary ossification centers or as rim fractures in the setting of dysplastic hips or hips with femoroacetabular impingement. Resection of a large os acetabuli can lead to structural instability of the joint, and in these cases, osteoplasty of the impingement, reduction and internal fixation of the osseous fragment, and labral repair have been described in the literature. Anchor fixation for labral repair in the surrounding zone of the osteosynthesis might bring some technical problems. We aim to describe a technical modification improving labral lesion treatment while addressing the rim fracture. The addition of a suture to the screw addresses both lesions because it simultaneously has the function of a screw and an anchor. A suture-on-screw technique for os acetabuli fixation helps surgeons to gain versatility and is more cost-effective for the patients and health services.

Arthroscopic Coracoclavicular Fixation Technique Using Multiple All-Suture Anchors.

Project description:Acromioclavicular (AC) joint dislocation is a common injury, particularly among active young individuals. Numerous surgical procedures for treating acute, high-grade AC joint dislocation have been reported. However, no standard surgical procedure that restores the normal kinematics of the AC joint is available. Among the available coracoclavicular (CC) fixation techniques, cortical button fixation was recently introduced, and it has had successful outcomes. Moreover, it is advantageous because it can be used in arthroscopic procedures. However, because of the limited number of fixation tools, a fundamental problem in terms of horizontal instability and gradual subsidence of cortical buttons has been observed, eventually leading to a threat to vertical stability. Therefore, we developed a unique CC fixation technique with multiple small tunnels using all-suture anchors, which may overcome potential complications caused by cortical buttons that require bone tunnels with relatively large diameters. This arthroscopic CC fixation technique was designed to achieve the ideal horizontal and vertical stability that may restore native AC kinematics.

Arthroscopic Fixation of Os Acetabuli Technique: When to Resect and When to Fix.

Project description:Acetabular rim fractures, or os acetabuli, are hypothesized to occur as a result of an unfused ossification center or a stress fracture from repetitive impingement of an abnormally shaped femoral neck against the acetabular rim. When treated surgically, these fragments are typically excised as part of the correction for femoroacetabular impingement. However, in some patients, removal of these fragments can create symptoms of gross instability or microinstability of the hip. In these cases, internal fixation of the fragment is necessary. The purpose of this technical note is to describe indications, the arthroscopic technique, and postoperative care for fixation of acetabular rim fractures.

Arthroscopic absorbable suture fixation for tibial spine fractures.

Project description:The purpose of this technical note and accompanying video is to describe a modified arthroscopic suture fixation technique to treat tibial spine avulsion fractures. Twenty-one patients underwent arthroscopic treatment for tibial spine avulsion with our technique; they were clinically and biomechanically evaluated at 2 years' follow-up and showed optimal clinical and radiographic outcomes. Repair with this arthroscopic technique provides a significant advantage in the treatment of type III and IV fractures of the tibial eminence by obtaining arthroscopic fixation within the substance of the anterior cruciate ligament: suture methods based on the avulsed bone fragment are technically impossible, but sutures through the base of the ligament itself provide secure fixation, reducing the risks of comminution of the fracture fragment and eliminating the time for hardware removal. This arthroscopic technique restores the length and the integrity of the anterior cruciate ligament and provides a simplified, reproducible method of treating patients, including young patients, with low hardware costs in comparison to sutures using anchors or other hardware.

Arthroscopic Posterior Glenoid Fracture Fixation Using Knotless Suture Anchors.

Project description:Shoulder instability after a posterior glenoid rim fracture is rare and potentially difficult pathology to treat. Operative techniques often involve a large dissection to view the fragments resulting in local soft tissue injury. Internal fixation is often achieved with interfragmentary screws; however, this may not be possible with small or multifragmentary fracture patterns. We describe an arthroscopic technique for posterior glenoid rim fracture fixation using knotless suture anchors. These anchors can be inserted without cannulas allowing easier access to the posterior glenoid. This procedure is simple, safe, and offers good visualization of the glenohumeral joint whilst avoiding the detrimental effects of larger surgical dissection.

Arthroscopic Double-Pulley Suture-Bridge Repair of Supraspinatus Tendon Tear.

Project description:At present, the suture bridge is a widely used surgical pattern in the treatment of supraspinatus tendon tear, but the shortcomings of a suture bridge, including expensive lateral-row anchor and increased type 2 retear rate, is obvious. The double-pulley suture-bridge described in this Technical Note uses a double-loaded suture anchor (medial-row anchor) as lateral-row anchor instead of traditional lateral-row anchor, combined with double-pulley technology forming suture-bridge in treatment of supraspinatus tendon tears. The surgical technique is described in pearls, pitfalls, advantages, and disadvantages.

Arthroscopic Bony Bankart Repair Using a Double-Row Double-Pulley Technique.

Project description:We propose an arthroscopic technique called "double-row double-pulley" to restore a bony Bankart lesion. This technique is a 2-point fixation construct using the sutures from a medial row anchor at the glenoid neck to wrap around the bony Bankart fragment and tie to the sutures from a lateral row anchor at the glenoid rim with the double-pulley method. This technique may present some difficulty with suture management, but there are several advantages. First, due to the 2-point fixation, the risk of a bone piece fracture from direct penetration is minimized. Moreover, the fragment can be reduced directly due to the multiple knots that are tied sequentially over the bony fragment.

Posterior Lateral Meniscus Root Reattachment With Suture Anchors: An Arthroscopic Technique.

Project description:The posterior lateral meniscus root (PLMR) provides the circumferential tension required to stabilize the lateral meniscus. Thus, preservation of the PLMR is important to prevent an increase in tibiofemoral contact pressure, which could result in osteoarthritis. We describe an all-arthroscopic approach to the fixation of PLMR using suture anchors through associated posterolateral arthroscopic portals that result in a more favorable inclination of the anchors. Initially, the anatomical insertion site of the root on the tibial plateau is debrided, 1 to 2 anchors are placed through the posterolateral portals into the root's footprint area, and the meniscus is finally sutured from the posterolateral portals. Compression of the meniscus is achieved with bone contact. This technique achieves lateral meniscus root fixation, reducing the risk of subluxation of the meniscus and subsequent osteoarthritis.
