Fracture of the scaphoid bone can be treated with cast immobilization or surgery. Historically, surgery was reserved for displaced fractures. However, because weeks of cast immobilization may result in stiffness, loss of strength, loss of bone density and an inability to work or participate in recreational activities for a prolonged period, operative treatment of non-displaced fractures has become increasingly common. Several surgical techniques for fixation have been described, but their risks and benefits have not yet been clearly elucidated. In a study in cadavers, we investigated whether one approach--volar percutaneous fixation--might pose a risk of injury to surrounding structures. ⋯ Our findings indicate that modification of the volar percutaneous approach to scaphoid fixation may be advisable to avoid damage to adjacent structures. We suggest use of a "mini-open" percutaneous procedure.

Comparative Study
Expedited Operative Care of Hip Fractures Results in Significantly Lower Cost of Treatment.
There are an estimated 150,000 hip fractures per year in the United States, with estimated costs of care between $10.3 billion and $15.2 billion. With such high costs and an increasing burden of care, there has been interest in newer methods to increase efficiency of care. One such method is expedited fracture care, with earlier operative intervention. The purpose of this study was to determine if intervention within six hours of admission decreased costs with no change in the rate of major complications. ⋯ Level IV, therapeutic case series.

Chronic Regional Pain Syndrome type I (CRPSI) in children is a disorder of unknown etiology. No standard diagnostic criteria or treatment exists. Published treatment protocols are often time and resource intensive. Nonetheless, CRPSI is not rare and can be disabling. This reports the results of a simple and inexpensive treatment protocol involving no medicines, nerve blockades, physical therapy resources or referrals to pain specialists. The patient is instructed in a self-administered massage and mobilization program. The diagnosis required allodynia (pain on light touch of the skin) and signs or the history of signs of autonomic dysfunction. ⋯ Therapeutic Level IV.

Fat embolism syndrome (FES) is a multi-organ disorder with potentially serious sequelae that is commonly seen in the orthopaedic patient population after femur fractures. The major clinical features of FES include hypoxia, pulmonary dysfunction, mental status changes, petechiae, tachycardia, fever, thrombocytopenia, and anemia. Due to technological advances in supportive care and intramedullary reaming techniques, the incidence of FES has been reported as low as 0.5 percent. ⋯ His symptoms included unresponsiveness, disconjugate gaze, seizures, respiratory distress, fever, anemia, thrombocytopenia, and visual changes. Head computed tomography and brain magnetic resonance imaging showed pathognomonic white-matter punctate lesions and watershed involvement. With early recognition and supportive therapy and seizure therapy, the patient went on to have complete resolution of symptoms without cognitive sequelae.

A laterally tracking patella is commonly seen in patients with chronic recurrent lateral patellar dislocations. Clinical appearance of the J-sign occurs when the patella is congruent with the trochlear groove in flexion and moves over the lateral border of the femoral condyle as the lower leg reaches complete extension. A Fulkerson osteotomy procedure corrects this maltracking of the patella by medially transferring the tibial tubercle. There are many radiographic patellofemoral indices that can be used describe this incongruence about the patelloformal joint. The current literature supports the use of the tibial tubercle-trochlear groove (TT-TG) index in determining the appropriate amount medialization of the extensor mechanism. However there is little agreement in how far to transfer the tibial tubercle to best achieve maximum patello-femoral congruency. It is the senior author's belief that lateral patellar edge (LPE) measure on voluntary quadriceps active hyperextension MRI scan has the strongest correlation with final operative tibial tubercle transfer distance needed to achieve maximum patellofemoral congruency. ⋯ The hypothesis that voluntary quadriceps active hyperextension MRI LPE measurement best correlated with tibial tubercle transfer distance was incorrect. The data collected showed correlation and statistical significance for voluntary quadriceps active flexion LPE with required tibal tubercle transfer distance (Pearson 0.34, alpha 0.026). The MRI measurement that best correlated with tibial tubercle transfer distance was voluntary quadriceps active flexion measure of TT-TG (Pearson .556, alpha< 0.001).
