Intraoperative Intra-articular Antibiotic Injection Reduces Infection in Shoulder Arthroplasty.

Deep infection is a debilitating complication after shoulder arthroplasty. The authors hypothesized that an intra-articular, intraoperative injection of antibiotics would result in a lower infection rate compared with intravenous antibiotics alone. Before 2007, 164 patients (group A) did not receive intra-articular antibiotics.

Intraoperative intra-articular injection of gentamicin: will it decrease the risk of infection in total shoulder arthroplasty?

Background: Deep infection is a debilitating complication after shoulder arthroplasty. Intra-articular injection of antibiotic can give a higher concentration compared with intravenous administration. We hypothesized that a group of patients given an intra-articular, intraoperative injection of gentamicin would report a lower infection rate than a group without local antibiotics.

Tensile strength of the end-weave flexor tendon repair. An in vitro biomechanical study.

A study was designed to investigate the tensile strength of the end-weave method of tendon repair. Flexor tendons were removed from 13 fresh-frozen human cadavers, transected and repaired with the end-weave technique varying from one to five weaves, with two suture techniques, the commonly used horizontal mattress suture and a new method we have termed the cross stitch. The repairs were then tested in tension to failure on a Materials Test System (MTS) biomechanical testing device.

Scapholunate advanced collapse pattern of arthritis in calcium pyrophosphate deposition disease of the wrist.

Chondrocalcinosis is a well-described radiographic finding in patients with calcium pyrophosphate dihydrate deposition disease of the wrist and other joints. The medical records and x-ray films of 12 patients evaluated over an 18-month period for chondrocalcinosis of the wrist were examined for symptoms and physical and x-ray film findings. Thirteen wrists were affected.

Scapulothoracic penetration of a Beath pin: an unusual complication of arthroscopic Bankart suture repair.

The arthroscopic Bankart suture repair technique is an alternative to open procedures that control anterior shoulder instability. A case is presented in which a Beath pin traveled through the scapula and penetrated the scapulothoracic articulation during arthroscopic Bankart repair. The authors caution that strict adherence to Morgan's technique should minimize complications with this procedure.
