Percutaneous screw fixation for unstable scaphoid fractures.

BACKGROUND: The technique of percutaneous screw fixation, with increasing popularity, has been successfully conducted in non-displaced, stable scaphoid fractures resulting in shortened immobilization duration and prompt functional retrieval. The purpose of this study was to evaluate the surgical technique and to explore the potential benefits of using percutaneous screw fixation in unstable scaphoid fractures. METHODS: Eleven of 97 patients with scaphoid fractures surgically treated between 1994 and 2002 were enrolled in this study. All were acute unstable fractures and underwent closed reduction and percutaneous screw fixation. All the records were meticulously reviewed and reported, including the complete radiographic examination before and after operation, time to fracture union, wrist motion, grip strength, and time of return to work, as well as overall patient satisfaction at the time of the most recent follow-up. RESULTS: Eleven fractures in an equal number of patients were followed up for a mean period of 1.6 years. All fractures acquired radiographic union in an average of 10.6 weeks. The modified Mayo Wrist score averaged 88.2. The functional result was ranked as excellent in 6 patients, and good in 5 patients. All returned to work or the pre-injury level of activity, and were satisfied with the surgical outcome. CONCLUSION: The technique of percutaneous screw fixation was successfully used to treat 11 unstable scaphoid fractures. The encouraging outcome of this treatment option and the prompt functional recovery deserve further investigation. Further randomized prospective studies to explore the specific indications and ubiquitous benefits of the technique presented herein are recommended.

Rush pin fixation versus traction and casting for femoral fracture in children older than seven years.

BACKGROUND: The optimal treatment for femoral fractures in children is controversial. The purpose of this study was to compare the results of Rush pin fixation with those of conservative treatment, and to evaluate the sequels of growth plate injury by internal fixation. METHODS: Eighteen femoral shaft fractures in 17 children who had concomitant head injury or multiple traumas were treated surgically. The mean age at operation was 9 years 3 months (range, 7 years 5 months to 11 years 1 month). One Rush pin was inserted from the tip of the greater trochanter, without reaming, to fix the fracture. Another 20 age-matched children treated by traction and casting were the control subjects. RESULTS: All the fractures united without consequences. In addition to a decrease in hospital stay with the use of the Rush pin (10 days vs. 27 days, p<0.05), fewer leg length discrepancies (4.2 mm vs. 7.1 mm, p<0.05) were also noted, compared with conservative treatment. The growth of the proximal femur after Rush pin fixation was evaluated after an average of 59 months. No femur shortening, coxa valgus, or hip dysplasia was noted. CONCLUSIONS: Intramedullary Rush pin fixation for femoral shaft fracture in children older than 7 years is a simple and reliable alternative. One narrow and non-reaming pin inserted from greater trochanter did not demonstrate femoral growth inhibition.

Acute primary hematogenous osteomyelitis of the epiphysis: report of two cases.

Acute primary infection of the epiphysis is uncommon. We present 2 cases of acute osteomyelitis of the distal femoral epiphysis. They were not diagnosed until 10 days and 3 weeks, respectively, after the onset of symptoms. The epiphyseal infection spread into the knee joint, and surgical debridement was performed. The majority of reported cases in the medical literature are of bacterial etiology, and the most common pathogen is Staphylococcus aureus. We report a rare case which was infected by Salmonella enteritidis. Prompt diagnosis and early treatment are required to prevent further destruction and growth disturbance.

Extension splint for trigger thumb in children.

Sixty-two reducible trigger thumbs in 50 children with age from 0 to 4 years (mean, 1 year 11 months) were reviewed to study the effect of splinting. Thirty-one thumbs in 24 children received splinting for a mean of 11.7 weeks. The other 31 thumbs in 26 children were only observed. The results were categorized as cured, improved, or nonimproved. Follow-up was conducted after a mean of 20 months (age, 43 months). Result in the splinted group showed cured in 12 thumbs, improved in 10 thumbs, and nonimproved in 9 thumbs, whereas in the observed group, result showed 4, 3, and 24, respectively. Splinting results in 71% trigger thumbs cured or improved that is better than observation alone. The subsequent surgical release for the nonimproved trigger thumbs after splinting still had excellent results. Because surgical release for trigger thumb is not urgent, we suggest extension splinting to be a treatment option before the elective surgery.
