Avoidance of Direct Posterior Portal During Elbow Arthroscopic Surgery in Posterior Compartment.

Arthroscopic surgery for the posterior compartment in elbow has been used in the treatment of many pathologies. The direct posterior portal has been commonly used for this compartment. However, this portal involves penetrating the triceps brachii tendon responsible for extensor mechanism.

The Arthroscopic Three-Point Fixation for Anterior Cruciate Ligament Avulsion Fracture: Surgical Technique.

Several arthroscopic repairs and fixation for tibial intercondylar eminence fracture have been developed for restoring anterior cruciate ligament function. Repairing the avulsion fragment with multiple-point fixation provides some benefits over a single-point fixation. It provides multidirectional force control, especially on the posterior part of the fragment, and produces area of compression.

The sonographic posterolateral rotatory stress test: Normal ulnohumeral gap difference in healthy volunteers.

The sonographic posterolateral rotatory stress test may be a good preoperative diagnostic tool for posterolateral rotatory instability, especially in atraumatic or occult cases. However, there is lack of study on the living population or the normal elbow. This study evaluates the ulnohumeral opening gap difference between elbows in resting and stress positions while performing ultrasonography in normal healthy volunteers.

Arthroscopic lateral collateral ligament imbrication for treatment of atraumatic posterolateral rotatory instability.

Background: Among the causative lesions of lateral elbow pain, atraumatic posterolateral rotatory instability (PLRI) is a rare condition, but it produces pain and disability to the elbow. It still lacks published specific treatment literature. According to the development of arthroscopy, the arthroscopic lateral collateral ligament (LCL) imbrication can possibly be an alternative minimal invasive procedure that can eradicate the atraumatic PLRI.

Arthroscopic Lateral Collateral Ligament Repair for the Acute Elbow Dislocation in Primary Lateral Sclerosis Patient: A Case Report.

Introduction: Without adequate muscle function as the dynamic elbow stabilizer, in a patient with a neuromuscular disorder, such as primary lateral sclerosis (PLS), the osteoligamentous structures are the only elbow stabilizers. To provide elbow stability, these structures should be restored.

Case: A 30-year-old female with PLS suffered from pain and dysfunction of her elbow after a previous elbow injury and current elbow dislocation.

Arthroscopic Lateral Collateral Ligament Complex Reconstruction for Posterolateral Rotatory Instability of the Elbow, the Operative Technique.

Posterolateral rotatory instability is concerning pathology in patients with recalcitrant lateral elbow pain. An arthroscopic technique can be used to perform reconstruction of lateral collateral ligament for eradicating the instability and also to manage concomitant lesions in a simultaneous operation. Similar to the modified Brostrӧm procedure using an inferior extensor retinaculum to augment the lateral collateral ligament for lateral ankle instability, in our Technical Note, we use anconeus muscles and annular ligament to augment the lateral collateral ligament for elbow instability during the reconstruction, allowing all tissue to heal with the bone by using a knotless technique.

Lateral collateral ligament reconstruction in atraumatic posterolateral rotatory instability.

Background: Chronic elbow pain has several causes. Instability pain is one of the differential diagnosis. Posterolateral rotatory instability (PLRI) of the elbow results from lateral collateral ligament (LCL) insufficiency.

Stress shielding around radial head prostheses.

Purpose: Stress shielding is known to occur around rigidly fixed implants. We hypothesized that stress shielding around radial head prostheses is common but nonprogressive. In this study, we present a classification scheme to support our radiographic observations.

The biomechanical effect of prosthetic design on radiocapitellar stability in a terrible triad model.

Objectives: The integrity of elbow soft tissues affects radiocapitellar joint stability in the presence of bipolar radial head (RH) prostheses. This study examined the effect on radiocapitellar stability of monopolar designs versus bipolar RH prostheses in an elbow model with a surgically controlled terrible triad injury.

Methods: In each of 8 fresh-frozen elbow specimens (4 male and 4 female), a terrible triad fracture dislocation was created through soft tissue releases, coronoid fracture, and RH resection.

Effect of hoop stress fracture on micromotion of textured ingrowth stems for radial head replacement.

Background: Successful bone ingrowth around cementless implants requires adequate initial stability. Hoop stress fractures during stem insertion can potentially hinder prosthesis stability.

Hypothesis: We hypothesized that an oversized radial head prosthetic stem (1 mm "too large" and causing a hoop stress fracture during insertion) would result in an unacceptable amount of micromotion.

Influence of prosthetic design on radiocapitellar concavity-compression stability.

Background: Radial head prostheses are available with multiple geometric properties. The effect of design features on radiocapitellar stability has not been investigated.

Hypothesis: The shape (depth and radius of curvature) of the articulating dish of a radial head prosthesis affects radiocapitellar stability.

Micromotion of plasma spray versus grit-blasted radial head prosthetic stem surfaces.

Background: Initial stability of a textured surface prosthetic stem is necessary for bone in-growth. Surfaces currently used for radial head prostheses include titanium plasma spray and grit-blasted titanium.

Hypothesis: Plasma spray radial head prosthetic stems are less dependent than grit-blasted stems on a tight press fit.

Radiocapitellar stability: the effect of soft tissue integrity on bipolar versus monopolar radial head prostheses.

Introduction: Radiocapitellar stability depends, in part, on concavity-compression mechanics. This study was conducted to examine the effects of the soft tissues on radiocapitellar stability with radial head prostheses.

Hypothesis: Monopolar radial head implants are more effective in stabilizing the radiocapitellar joint than bipolar radial head prostheses, with the soft tissues intact or repaired.

Radial head prosthesis micromotion characteristics: Partial versus fully grit-blasted stems.

Background: Compared to fully textured prosthetic stems, partial texturing lessens bone loss due to stress shielding and makes removal easier. However, initial press-fit stability is necessary for bone ingrowth.

Hypothesis: There is no significant difference in the initial stability of radial head prostheses that are partially grit-blasted compared to those that are fully grit-blasted.
