Open talar dislocations without associated fractures.

AIM: Total dislocation of the talus first reported in 1680. It is a rare injury and without associated fractures is even rarer. Is generally considered to be one of the most disabling ankle injuries and occurs after high energy trauma. The primary goal of our study is the retrospective evaluation of complete talar extrusion without associated fractures and immediate reimplantation. MATERIALS AND METHODS: In the past nine years, nine patients with mean age 31.7 years were admitted to our center with a complete open talar extrusion. The dislocated talus was reduced and held in place with two Steinmann pins placed from the inferior aspect of the calcaneus, through the talus and into the inferior aspect of the tibia. An external fixator was used to stabilize the limb. The mean follow up time was 21.1 months. At the last follow up visit, six patients were evaluated both radiographically and functionally with the AOFAS score. RESULTS: Six patients were free of complications and the mean AOFAS Ankle-Hindfoot Scale score at the time of the last follow up visit was 82.5. Two patients had an infection, one had avascular necrosis of the talus and one had signs of subtalar joint arthritis. Two patients had to undergo arthrodesis. CONCLUSIONS: It is important to attempt reimplantation of the talus since a good final outcome is to be expected. Even in the case of a catastrophic complication this technique will ensure adequate bone stock for additional surgical procedures.

Sonication: a valuable technique for diagnosis and treatment of periprosthetic joint infections.

BACKGROUND: Periprosthetic joint infection (PJI) is the most severe complication, following joint arthroplasty. Identification of the causal microbial factor is of paramount importance for the successful treatment. PURPOSE: The aim of this study is to compare the sonication fluid cultures derived from joint prosthetic components with the respective periprosthetic tissue cultures. METHODS: Explanted prosthesis components for suspected infection were placed into a tank containing sterile Ringer's solution and sonicated for 1 minute at 40 kHz. Sonication fluid cultures were examined for 10 days, and the number and identity of any colony morphology was recorded. In addition, periprosthetic tissue specimens (>5) were collected and cultured according to standard practice. The duration of antimicrobial interruption interval before culture sampling was recorded. RESULTS: Thirty-four patients composed the study group. Sonication fluid cultures were positive in 24 patients (70.5%). Sixteen of thirty four periprosthetic tissue cultures (47.1%) were considered positive, all revealing the same microbial species with the respective sonication fluid cultures: 3 tissue samples showed polymicrobial infection. All tissue cultures were also found positive by the sonication fluid culture. CONCLUSIONS: Sonication fluid cultures represent a cheap, easy, accurate, and sensitive diagnostic modality demonstrating increased sensitivity compared to periprosthetic tissue cultures (70.5 versus 47.1%).

Charnley low-friction arthroplasty in patients 35 years of age or younger. Results at a minimum of 23 years.

We evaluated the outcome of 41 consecutive Charnley low-friction arthroplasties (LFAs) performed by a single surgeon in 28 patients aged ≤ 35 years at operation between 23 and 36 years previously. There were 20 women and eight men with a mean age of 32 years (23 to 35) at surgery. Two patients (three hips) were lost to follow-up at 12 and 17 years post-operatively, respectively, and one patient (one hip) died at 13 years post-operatively. These patients were excluded from the final evaluation. The survival rate of the acetabular components was 92.7% (95% confidence interval (CI) 88.7 to 96.7) at ten years, 67.1% (95% CI 59.75 to 74.45) at 20 years and 53.2% (95% CI 45.3 to 61.1) at 25 years. For the femoral component the survival was 95.1% (95% CI 91.8 to 98.5) at ten years, 77.1% (95% CI 73.9 to 80.3) at 20 years and 68.2% (95% CI 60.7 to 75.8) at 25 years. The results indicate that the Charnley LFA remains a reasonable choice in the treatment of young patients and can serve for comparison with newer techniques and implants.

Treatment of osteitis pubis in non-athlete female patients.

BACKGROUND: Osteitis pubis represents a non-infectious inflammation of the pubic symphysis causing varying degrees of lower abdominal and pelvic pain. Although, the disease is believed to affect mainly young athletic patients, it is also encountered in other specific patient groups. Both conservative and surgical treatment options are available. While for elite athletes surgical treatment is indicated, leading to fast pain relief and mobilization, for non-athletic patients no clear indication can be established. METHODS: Eight non-athletic women with osteitis pubis, referred to our Department for treatment, were evaluated. All were initially treated conservatively with bed rest, per os non steroidal anti-inflammatory drugs and physical therapy. RESULTS: Seven patients improved significantly with conservative treatment while one displayed no improvement and was treated surgically with arthrodesis. CONCLUSION: We conclude that, for non-athletic female patients suffering from osteitis pubis, surgery is rarely required and that conservative treatment by means of non steroidal anti inflammatory drugs and physical modalities represents a fair option regarding pain and limitation of everyday activity.

Recto-femoral fistula presenting as emphysematous cellulitis of the knee: a case report & literature review.

Purpose. The rectofemoral fistula represents a devastating complication of colorectal surgery. Its early diagnosis and treatment are critical to obtain a good patient outcome. Case Presentation. A 75-year-old Caucasian female patient presented with high fever, ileus, low back pain, sciatic nerve palsy, and infection of the right knee. After numerous surgical debridements and antibiotic therapies, a rectofemoral fistula was diagnosed. Conclusion. Increased doctors' alertness is mandatory for the early identification and surgical treatment of patients suffering from a rectofemoral fistula before the stage of diffuse infection has significantly decreases their postoperative morbidity and mortality.

Long-term outcome of patients with avascular necrosis, after internal fixation of femoral neck fractures.

We retrospectively reviewed 84 patients who underwent internal fixation of an intracapsular femoral neck fracture. The mean age was 58 years and the time from injury to operative treatment was 5.3 days. The mean follow-up was 4.7 years (range, 2-8 years). At the latest follow-up, in the 46 patients with undisplaced (Garden I, II) fractures, nonunion occurred in two patients and avascular necrosis of the femoral head in nine. Six of these nine patients had a good or excellent result, one had a fair result, and two had a poor result. Of 35 patients with no sign of avascular necrosis, 32 patients had a good or excellent result, two a fair and one had a poor result. In the group of 38 patients with displaced (Garden III, IV) fractures, nonunion occurred in six patients and avascular necrosis of the femoral head in 15. Of these 15 patients, 10 had a good or excellent result, two had a fair result, and three had a poor result. Of 17 patients with no sign of avascular necrosis, 14 had an excellent result and three patients a poor result. Overall only five of the 24 patients who developed avascular necrosis of the femoral head had undergone total hip arthroplasty. Internal fixation remains a simple and safe, method of treatment for both undisplaced and displaced femoral neck fractures in middle-age patients. Despite the relatively high rate of avascular necrosis after internal fixation of femoral neck fractures, only a few of these patients (20%) required further surgical treatment in the follow-up period of this study.

Halo pin intracranial penetration and epidural abscess in a patient with a previous cranioplasty: case report and review of the literature.

STUDY DESIGN: Report of a patient with an epidural abscess after halo pin intracranial penetration at the site of a previous cranioplasty. OBJECTIVES: To report a rare case of intracranial penetration at the site of a previous cranioplasty associated with epidural abscess, and to discuss the diagnostic and therapeutic approach to its management. SUMMARY OF BACKGROUND DATA: The most serious complications associated with use of halo device occur when pins penetrate the inner table of the skull, resulting in cerebrospinal fluid leak and rarely in an intracranial abscess. However, no mention of intracranial halo pin penetration at the site of a previous cranioplasty was found in the literature. METHODS: A 64-year-old man with ankylosing spondylitis had a halo vest placed for management of a fracture dislocation through the C5-C6 intervertebral disc space associated with left C6 radiculopathy. One week later, the patient experienced fever and headache associated with pain, redness, and drainage at the site of the insertion of the left posterior pin. Computed tomography of the brain showed a 1.5-cm intracranial penetration of the halo pin through a previous cranioplasty of the temporal bone, associated with epidural abscess and cerebral edema in the left temporoparietal lobe. The pins and the halo vest were removed, the pin site was cleaned, and a Philadelphia cervical collar was applied. Staphylococcus epidermidis grew on the culture of drainage from the pin site. The patient started immediate intravenous antibiotic treatment for 2 weeks, followed by oral antibiotics for 2 additional weeks. RESULTS: The patient had gradual improvement of his symptoms within the first 48 hours. At the latest follow-up visit, he had fully recovered and his fracture had healed. CONCLUSIONS: The halo device should not be used for patients with a previous cranioplasty, especially if the pins cannot be inserted at other safe areas of the skull. A thorough medical history and physical examination of the skull are important before the application of a halo device. Computed tomography of the skull may be necessary before elective halo application for patients with concomitant head trauma, confusion, or intoxication and for patients with a previous cranioplasty to ascertain the safest pin sites.

Treatment of lumbosacral radicular pain with epidural steroid injections.

Fifty patients with an average age of 47 years received epidural steroid injections for lumbosacral radicular pain due to disk herniation or spinal stenosis. All patients had failed previous conservative treatment. Mean follow-up was 24 months (range: 12-36 months). Immediately after injection, all 50 patients reported various degrees of relief from leg and back pain. At the last follow-up examination, 68% of patients were asymptomatic, 20% had no change in preinjection radicular symptoms, and 12% had various degrees of relief. No significant correlation was found between pain relief, age, or number of injections. Early pain relief may be anticipated after epidural steroid injections in 80% of patients with radicular symptoms due to disk herniation or spinal stenosis.
