Nonpalmar Endoscopic versus Open Trigger Finger Release: Results from a Prospective Trial.

The most common complaint after open surgical release for trigger finger is of pain and scarring at the surgical site. We hypothesized that use of a new nonpalmar endoscopic approach for release of the A1 pulley through an incision at the proximal digital crease would result in decreased scarring and faster recovery compared to those treated with standard open release. Methods: Patients with trigger finger were prospectively enrolled and treated with a nonpalmar endoscopic versus open surgical technique. Outcome measures included scar assessment based on the Patient and Observer Scar Assessment Scale (POSAS) administered 1 week, 1 month, and 6 months postoperatively, time before return to work, occupational therapy visits, and overall satisfaction. Additional outcomes included pain medication use, operative time, and complication and recurrence rates. Results: POSAS scores were better in the endoscopic treatment group than in the open group at all time points with a statistically significant difference seen at 1 week and 1 month postoperatively. The endoscopic group returned to work sooner, required fewer occupational therapy visits, and had better overall satisfaction compared to the open group, but the differences were not statistically significant. Complication and recurrence rates did not differ significantly between groups. Conclusions: Patients treated for trigger finger with a nonpalmar endoscopic release through an incision at the proximal digital crease demonstrate significantly better scarring in the early postoperative period compared to patients treated with the open surgical approach. Treatment for trigger finger with this technique is as effective as the standard open technique.

Endoscopic Retrograde Approach for Trigger Finger Release: A Cadaver Study.

Trigger finger is one of the most common causes of disability and pain in the hand. Current surgical techniques for trigger finger release fall short in that they are performed blindly with trauma to, or require incision of, the palmar fascia, which can be a source of significant and long-lasting morbidity. Retrograde endoscopic release of the A1 pulley was performed through a single incision at the proximal digital crease in cadaveric specimens. The fingers were then dissected to assess for completeness of release and inspected for injury to nearby structures. Complete release of the A1 pulley was noted in 16 of 16 fingers. No significant injuries to the A2 pulley and flexor tendon were found, and no injuries to the digital nerves or vasculature occurred. The described technique, as demonstrated in cadaveric specimens, is a feasible alternative approach in the treatment of trigger finger. The technique allows complete visualization of A1 pulley release through a single palmar fascia sparing incision.

Current safety sterilization and tissue banking issues for soft tissue allografts.

Allografts used in orthopedic surgery have steadily increased. With concerns regarding tissue safety and processing, governing entities have increased their regulation. This review articles discusses current testing and processing of allografts as well as the rules of their handling.

New techniques in allograft tissue processing.

With the increasing reliance on tissue allografts in orthopedic reconstructive and sports surgery, there is a realistic concern on behalf of both the surgeon and the patient as to the safety of these implanted tissues and the possibility of disease transmission. New Food and Drug Administration guidelines in association with independent agency scrutiny have served to decrease this risk in light of recent publicized reports of infection transmission associated with allograft use. In addition, tissue banks are constantly developing new proprietary techniques for allograft processing and sterilization. However, clinical studies are needed to validate disinfection efficacy and to evaluate the effect of these processes on tissue structural properties. This article serves as a review of historical disease transmission, current governmental and nongovernmental tissue regulations, and specific processing techniques used by tissue banks.

Septic arthritis in patients with human immunodeficiency virus.

The literature contains few descriptions of the infective organisms and diagnostic issues associated with musculoskeletal infections in patients with HIV. We retrospectively reviewed 19 patients with HIV treated at our musculoskeletal infection ward for septic arthritis. The mean CD4 count was 154/mm (range, 7-482/mm), and 11 patients had a CD4 count < 200/mm and were diagnosed with AIDS. The most common pathogen (six patients) was oxacillin-resistant Staphylococcus aureus. Mycobacterial infections occurred in three patients but no fungal pathogens were identified. Septic arthritis was monoarticular in 14 patients and involved the knee in eight patients, the hip in three patients, and the wrist in three patients. Five patients presented with polyarticular septic arthritis. All mycobacterial infections and four of the five polyarticular infections occurred in patients with a CD4 count < 200/mm. Patients with CD4 count < 200/mm had a lower joint fluid WBC count compared to patients with a CD4 count > 200/mm (40,500 vs 69,000/mm). Oxacillin-resistant Staphylococcus aureus was the most common pathogen. A high index of suspicion for Mycobacterium. tuberculosis arthritis and polyarticular septic arthritis is necessary in patients with HIV and a CD4 count < 200/mm.

Recalcitrant septic knee arthritis due to adjacent osteomyelitis in adults.

We asked whether adjacent osteomyelitis with acute septic knee arthritis explained a lack of response to initial management, and whether patient comorbidities predisposed to the nonresponsiveness. From 147 adult patients (151 knees) with septic arthritis, we identified 29 patients (33 knees) who had persistence or recurrence of symptoms after surgical drainage. Adjacent osteomyelitis was present in 31 (94%) of the 33 knees (27 of 29 patients) with poor response to treatment. Patients with adjacent osteomyelitis had more comorbid conditions (23 of 27 patients, 85%) than patients without osteomyelitis (64 of 120, 53%). The most common comorbid conditions in patients with adjacent osteomyelitis were diabetes mellitus (10 patients, 37%) and intravenous drug use (eight patients, 30%). We identified Staphylococcus aureus in 19 of 31 knees (61%) with osteomyelitis, eight (26% of total cases) of which were methicillin-resistant. Persistence of clinical signs of infection after surgical management of septic knee arthritis in adults should raise the suspicion of adjacent osteomyelitis, especially in patients with comorbid conditions. Additional imaging studies may be necessary to evaluate the distal femur and proximal tibia.
