The effect of opening wedge thoracostomy on thoracic insufficiency syndrome associated with fused ribs and congenital scoliosis.
Thoracic insufficiency syndrome is the inability of the thorax to support normal respiration or lung growth and is seen in patients who have severe congenital scoliosis with fused ribs. Traditional spinal surgery does not directly address this syndrome. ⋯ Opening wedge thoracostomy with use of a chest-wall distractor directly treats segmental hypoplasia of the hemithorax resulting from fused ribs associated with congenital scoliosis. The operation addresses thoracic insufficiency syndrome by lengthening and expanding the constricted hemithorax and allowing growth of the thoracic spine and the rib cage. The procedure corrects most components of chest-wall deformity and indirectly corrects congenital scoliosis, without the need for spine fusion. The technique requires special training and should be performed by a multispecialty team.

Operative treatment of femoral neck fractures in patients between the ages of fifteen and fifty years.
There is a paucity of data on the treatment of femoral neck fractures in young patients. The purpose of the present study was to review the results and complications associated with the treatment of femoral neck fractures with internal fixation in a large consecutive series of young patients. ⋯ The ten-year survival rate of the native femoral head free of conversion to total hip arthroplasty was 85%. Osteonecrosis was the main reason for conversion to total hip arthroplasty, but not all patients with osteonecrosis required further surgery. The results of treatment were influenced by fracture displacement and the quality of reduction.

Multicenter Study Comparative StudyFunctional outcomes following trauma-related lower-extremity amputation.
The principal aims of this study were to examine functional outcomes following trauma-related lower-extremity amputation and to compare outcomes according to the amputation levels. We hypothesized that above-the-knee amputations would result in less favorable outcomes than would through-the-knee or below-the-knee amputations. A secondary aim was to examine the factors, in addition to amputation level, that influence outcome, including the type of soft-tissue coverage, selected patient characteristics, and the technological sophistication of the prosthetic device. ⋯ Severe disability accompanies above-the-ankle lower-extremity amputation following trauma, regardless of the level of amputation. Clinicians should critically evaluate the need for a through-the-knee amputation in patients with a traumatic injury. The results of this study also underscore the need for controlled studies that examine the relationship between the type and fit of prosthetic devices and functional outcomes.

The most common cause of iatrogenic flatback syndrome is Harrington distraction instrumentation extending into the lower lumbar spine. Other common causes and exacerbating factors include failure to enhance regional lordosis during lumbar fusion for degenerative spondylosis, development of pseudarthrosis or postoperative loss of correction, development of kyphosis at the thoracolumbar junction, development of degeneration and decompensation cephalad or caudad to a prior fusion, and hip flexion contractures. ⋯ Polysegmental osteotomies and vertebral column resection may be utilized in cases of sloping global sagittal imbalance and related severe coronal imbalance, respectively. Following surgical treatment, sagittal balance is generally improved with fair-to-good clinical outcomes, high patient satisfaction, and moderately high perioperative complication rates.

Talar neck fractures occur infrequently and have been associated with high complication rates. The purposes of the present study were to evaluate the rates of early and late complications after operative treatment of talar neck fractures, to ascertain the effect of surgical delay on the development of osteonecrosis, and to determine the functional outcomes after operative treatment of such fractures. ⋯ Fractures of the talar neck are associated with high rates of morbidity and complications. Although the numbers in the present series were small, no correlation was found between the timing of fixation and the development of osteonecrosis. Osteonecrosis was associated with talar neck comminution and open fractures, confirming that higher-energy injuries are associated with more complications and a worse prognosis. This finding was strengthened by the poor Foot Function Index and Musculoskeletal Function Assessment scores in these patients. We recommend urgent reduction of dislocations and treatment of open injuries. Proceeding with definitive rigid internal fixation of talar neck fractures after soft-tissue swelling has subsided may minimize soft-tissue complications.
