Posterior glenoid reconstruction using distal tibia allograft is an available technique for the treatment of posterior shoulder instability with glenoid bone loss. A key aspect to this procedure relies on maintaining complete control of the graft during insertion and securement to the posterior glenoid. Although there are commercially available products to aid with graft control, we describe a ...

The posterior cruciate ligament (PCL) is known to be the main posterior stabilizer of the knee. Anatomic single-bundle PCL reconstruction, focusing on reconstruction of the larger anterolateral bundle, is the most commonly performed procedure. Because of the residual posterior and rotational tibial instability after the single-bundle procedure and the inability to restore the normal knee kinema...

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 art...

Traumatic glenohumeral dislocations often result in significant injury to the anterior-inferior labrum, most commonly leading to recurrent anterior instability. While in skeletally immature patients, shoulder trauma more commonly results in fracture versus a true dislocation, shoulder instability does occur and can be difficult to manage in the setting of open physes. In any event, the goal of ...

OBJECTIVE To carry out an anatomical study of the medial collateral ligament, an important elbow stabilizer in different degrees of elbow flexion-extension. METHODS Forty elbows were dissected in order to analyze the functional behavior of the anterior, posterior and transverse ligament bands during valgus stress maneuvers of the elbow in different degrees of flexion and extension. Two groups...

A group of 40 patients with unstable knees due to a combination of a meniscal tear with a rupture of the anterior cruciate ligament was studied to assess the effects of treatment by meniscectomy alone. The results were assessed both subjectively and objectively, but emphasis was placed on the symptoms rather than the physical signs of instability. Meniscectomy alone cured the symptoms of instab...

Instability following sagittal distraction and rotational injuries of the cervical spine has been widely reported. We here report a case of post-traumatic segmental instability in the coronal plane. Case report. A 66-year-old farmer presented with painful torticollis having fallen into a ditch the previous day. He experienced immediate neck pain, but did not lose consciousness. He had a left te...

Glenoid morphology has an important impact on outcomes and complication rates after shoulder arthroplasty for primary glenohumeral arthritis. The B2 glenoid, or a biconcave glenoid with posterior humeral head subluxation, in particular has been associated with a poorer outcome with shoulder arthroplasty compared with other glenoid types. A variety of techniques may be used to address the bone d...

Between June 1983 and March 1992, we performed a capsular reconstruction procedure through an anterior approach in ten patients (ten shoulders) who had multidirectional laxity of the shoulder and symptomatic atraumatic posterior glenohumeral instability. The procedure included closure of the capsule in the rotator interval and imbrication of the anterior, inferior, and posteroinferior aspects o...

A 44-year-old man with anterior megalophthalmos arrived at the clinic presenting a cataract in the right eye. The corneal diameter was 13 mm. Iridodonesis and phacodonesis were evident during slit lamp examination. Anterior chamber depth was 5.89 mm, and the diameter of the capsular bag was approximately 14.45 mm. Due to the large capsular bag, a standard posterior chamber intraocular lens was ...
