The Impact of Superior Labral Anterior to Posterior Lesions on Functional Status in Shoulder Instability: A Multicenter Cohort Study.

Background: Type IV superior labral anterior to posterior (SLAP) lesions, which are superior labral detachments associated with Bankart tears, are reported to occur in up to 25% of recurrent shoulder instability patients. However, the clinical implications of this finding are debatable.

Purpose: To determine whether there are any functional differences between anterior instability patients with and without type IV SLAP lesions at the time of presentation and at short-term follow-up after surgical intervention.

Validation of the instability shoulder index score in a multicenter reliability study in 114 consecutive cases.

Background: Anterior shoulder stabilization surgery with the arthroscopic Bankart procedure can have a high recurrence rate in certain patients. Identifying these patients to modify outcomes has become a focal point of research.

Purpose: The Instability Shoulder Index Score (ISIS) was developed to predict the success of arthroscopic Bankart repair.

Direct MR arthrography of the shoulder under axial traction: feasibility study to evaluate the superior labrum-biceps tendon complex and articular cartilage.

Purpose: To assess the value of adding axial traction to direct MR arthrography of the shoulder, in terms of subacromial and glenohumeral joint space widths, and coverage of the superior labrum-biceps tendon complex and articular cartilage by contrast material.

Materials And Methods: Twenty-one patients investigated by direct MR arthrography of the shoulder were prospectively included. Studies were performed with a 3 Tesla (T) unit and included a three-dimensional isotropic fat-suppressed T1-weighted gradient-recalled echo sequence, without and with axial traction (4 kg).

Outcome of single-tendon rotator cuff repair in patients aged older than 65 years.

Background: Rotator cuff repairs in patients aged older than 65 years are reported to have a high failure rate. Furthermore, asymptomatic cuff tearing is frequent in this age group, so the value of tendon repair has been questioned. Our aim was to review the results of cuff repair in these patients and to identify factors predicting outcome.

Assessment of glenoid inclination on routine clinical radiographs and computed tomography examinations of the shoulder.

Background: Accurate assessment of glenoid inclination is of interest for a variety of conditions and procedures. The purpose of this study was to develop an accurate and reproducible measurement for glenoid inclination on standardized anterior-posterior (AP) radiographs and on computed tomography (CT) images.

Materials And Methods: Three consistently identifiable angles were defined: Angle α by line AB connecting the superior and inferior glenoid tubercle (glenoid fossa) and the line identifying the scapular spine; angle β by line AB and the floor of the supraspinatus fossa; angle γ by line AB and the lateral margin of the scapula.

Radial head translation measurement in healthy individuals: the radiocapitellar ratio.

Hypothesis: We hypothesized that the radiocapitellar ratio (RCR) is a valid and reproducible method to assess radial head translation in healthy individuals and that the normal RCR of healthy individuals is 0%.

Materials And Methods: Lateral radiographs of the elbow were examined in 40 healthy patients. The measurement method of the RCR was the displacement of the radial head (minimal distance between the right bisector of the radial head and the center of the capitellum) divided by the diameter of the capitellum.

[When to operate an isolated midshaft clavicle fracture?].

Slightly displaced clavicular midshaft fracture is currently treated nonoperatively. There is considerable debate about whether acute displaced fractures should be treated operatively. Nonunion rate after displaced fracture has been underestimated for a long time, and malunion clinical impact often minimized.

Closed and open grade I and II tibial shaft fractures treated by reamed intramedullary nailing.

Objective: To evaluate the results of closed and open grade I and II tibial shaft fractures treated by reamed nail and unreamed nailing.

Subjects And Methods: Between 1997 and 2000, 119 patients with tibial shaft fractures were treated with reamed tibial nails. Postoperatively 96 patients (70 closed and 26 grade I and II open fractures) were followed clinically and radiologically for up to 18 months.

Revision anterior cruciate ligament reconstruction with quadriceps tendon-patellar bone autograft.

Purpose: To evaluate the cause of recurrent pathologic instability after anterior cruciate ligament (ACL) surgery and the effectiveness of revision reconstruction using a quadriceps tendon autograft using a 2-incision technique.

Type Of Study: Retrospective follow-up study.

Methods: Between 1999 and 2001, 31 patients underwent ACL revision reconstruction because of recurrent pathologic instability during sports or daily activities.

Locking knee caused by subluxation of the posterior horn of the lateral meniscus.

The authors report a case of repetitive locking knee caused by a subluxation of the posterior horn of a normal lateral meniscus. The posterior horn was sutured to the posterior knee capsule and the athlete resumed complete sports activity 4 months after the surgery.
