Case Reports
Acute compartment syndrome of the foot following fixation of a pilon variant ankle fracture.
Acute traumatic compartment syndrome of the foot is a serious potential complication after fractures, crush injuries, or reperfusion injury after vascular repair. Foot compartment syndrome in association with injuries to the ankle is rare. This article presents a case of acute compartment syndrome of the foot following open reduction and internal fixation of an ankle fracture. ⋯ Emergently, fasciotomy of both compartments was performed through a medial incision. Postoperatively, the patient reported immediate pain relief. At 18-month follow-up, she reported no pain and had returned to all of her preinjury athletic activities.

This article describes the effect of closed reduction and internal fixation with 3 different screw configurations for acute completely displaced femoral neck fractures in young adults. From 2001 to 2006, 136 patients (age range, 20-50 years) who had acute unilaterally completely displaced femoral neck fractures were evaluated retrospectively. All fractures were managed with closed reduction and internal fixation with 3 cannulated screws. ⋯ The average duration from injury to surgery was 17.3 hours in the avascular necrosis of the femoral head group and 22.3 hours in the non-avascular necrosis of the femoral head group, with no statistical significance (P=.155). Vertical- and separated-type screw configurations resulted in a significantly higher nonunion rate (P=.001 and P=.0017, respectively) than parallel configuration. The complication rate in treating completely displaced femoral neck fractures with internal fixation in young adults is high, and screw configuration may further affect results.

Axial lumbar interbody fusion is a novel percutaneous alternative to common open techniques, such as anterior, posterior, and transforaminal lumbar interbody fusion. This minimally invasive technique uses the presacral space to access the L5-S1 and L4-L5 disk space. The goal of this study was to examine outcomes following axial lumbar interbody fusion. ⋯ The most common complications were superficial infection and pseudoarthrosis. Other complications were rectal injury, hematoma, and irritation of a nerve root by a screw. Overall, we found the axial lumbar interbody fusion procedure in combination with pedicle screw placement to have good clinical and radiological outcomes.

Percutaneous kyphoplasty is a minimally invasive technique that has become an effective and routine alternative for managing osteoporotic vertebral compression fractures. This article reports the clinical outcome of a series of 54 cases of osteoporotic thoracolumbar vertebrae compression fractures treated by percutaneous kyphoplasty. Fifty-four patients with confirmed osteoporosis and at least 1 level of thoracolumbar vertebrae compression fracture were retrospectively selected. ⋯ The cement leakage rate was 3.86% (8 of 207 vertebrae) with percutaneous kyphoplasty, but no neurological or other complaints were received. Percutaneous kyphoplasty is a simple and safe procedure in managing osteoporotic vertebrae compression fractures. It relieves pain quickly, restores vertebral height, prevents further fracture, and improves patient quality of life.

The effects of ipsilateral cervical nerve root transfer on the restoration of the rat upper trunk muscle and nerve brachial plexus root avulsion were studied. After simulated root avulsion of the upper trunk brachial plexus, 120 rats were randomly divided into 4 groups: (A) ipsilateral C7 root transfer group; (B) Oberlin group; (C) phrenic nerve group; and (D) no axillary nerve restoration group. At 3, 6, and 12 weeks postoperatively, Ochiai score, Barth feet overreaching test, Terzis grooming test, and indices of neurotization were determined in 10 rats from each group. ⋯ No significant difference was found between the ipsilateral C7 group and the phrenic nerve and no axillary nerve restoration groups in amplitude recovery rate of musculocutaneous nerve compound muscle action potential. No significant difference was found between the ipsilateral C7 and the Oberlin groups in the early recovery of musculocutaneous nerve compound muscle action potential, but recovery was significantly better in the ipsilateral C7 group at 12 weeks. Ipsilateral C7 root transfer can improve the quality of restoration of muscle and nerve function in the rat upper trunk after brachial plexus root avulsion.
