Excessive complications of open intramedullary nailing of midshaft clavicle fractures with the Rockwood Clavicle Pin.

Background: Intramedullary clavicle fixation is a potential alternative to plate fixation. Previous studies documenting the complication rates of intramedullary clavicle fixation have demonstrated variable rates of soft tissue complications and fracture healing.

Questions/purposes: We asked the following questions: (1) Does use of the Rockwood Clavicle Pin (DePuy Orthopaedics Inc, Warsaw, IN) predispose patients to soft tissue complications requiring additional surgery or a high infection risk? (2) Does the Rockwood Clavicle Pin provide a truly minimally invasive insertion technique and reliable fracture fixation?

Patients And Methods: We retrospectively evaluated 18 patients (mean age, 31 years) who sustained a closed midshaft fracture of the clavicle treated with open intramedullary nailing with a Rockwood Clavicle Pin.

An in vitro biomechanical investigation: variable positioning of leopard carbon fiber interbody cages.

Study Design: This study is a biomechanical analysis of intervertebral cage placement, using a biomechanical model that has the appropriate matching geometry of the lumbar spine at the level of L4-L5 based upon prior morphometric studies.

Objective: The goal of this in vitro biomechanical analysis of interbody cages is to determine the effect of interbody cage position on the mechanics of posterior spinal instrumentation. This biomechanical analysis can potentially be used to guide surgical technique for placement of interbody cage devices.

Cervical degenerative cyst located within the body of C2: a case report and review of the literature.

Study Design: A case report and review of the literature are presented.

Objectives: To describe the clinical course and treatment of a patient with an unusual intraosseous degenerative cyst within the body of the axis, as well as review the literature regarding these lesions.

Summary Of Background Data: Intraosseous degenerative cysts of the cervical spine are extremely rare.

The role of debridement and antibiotics in gunshot wounds to the spine.

Background: The number of spinal cord injuries due to gunshot wounds continues to rise each year, and they currently rank third behind motor vehicle collisions and falls. Spine and wound infections pose difficult problems for transgastrointestinal gunshot wounds to the spine.

Methods: A retrospective review of 114 patients with low-velocity gunshot wounds to the spine was performed.
