Nail Bed Injury Repair: Nail Plate Replacement Versus Non-replacement.

Background: Although nail bed injuries are common, there is no consensus on the proper course of treatment in regard to nail plate replacement. Nail plate replacement risks infection and injury of the germinal matrix. It is our hypothesis that functional and cosmetic outcomes of the nail will not differ by nail plate replacement following nail bed repair. Methods: This is a single institution, prospective, randomized control study comparing nail plate replacement versus non-replacement in patients undergoing nail bed repair. Primary outcome included nail growth and cosmesis using the Zook classification system. Secondary outcomes were pain, functional limitation, and patient satisfaction. Statistical significance was set at P < .05. Results: Fifty patients were enrolled, 26 (52%) randomized to the non-replacement group and 24 (48%) to the replacement group. All patients who followed up had nail growth by 4 months after nail bed repair (N = 28). In the non-replacement group 4 patients continued to have pain in the affected nail bed compared with 2 patients in the replacement group (P = .66). One patient in each group reported continued functional limitation related to nail pain (P = 1.00). Patient satisfaction was not statistically different between the groups (P = 1.00). As a result of patient follow- up, we have been able to score 17 patients via the Zook criteria. In the non-replacement group, 3 nails were scored as excellent, 3 very good, 3 good, 1 fair, and 2 poor. In the replacement group, the nail was classified as excellent in 4 patients and very good in 1 patient. There was no difference in the likelihood of these outcomes with regard to treatment group (P = .18). There was moderate agreement between patient satisfaction and the Zook criteria scoring (κ = .45, 95% CI: -0.15-1.00). Conclusions: Statistical and clinical differences were not identified in regard to cosmesis, pain, functional use of the hand, or patient satisfaction. There are established risks involved in nail plate replacement such as infection and injury to the germinal matrix. If outcomes are not different based on nail plate replacement following nail bed repair, non- replacement may be the preferable treatment option so as to avoid these complications.

Congenital Deformities of the Hands.

Evaluation of the pediatric musculoskeletal system may be difficult because of differences between children and adults. As children mature, their physical structure approaches that of an adult. However, in the meantime, varying stages of ossification and developmental timelines may confuse the average clinician. Congenital abnormalities of the upper extremity are extremely numerous, but here we present 10 that often are seen in clinical practice. The article discusses the diagnosis, evaluation, treatment, and outcomes of each condition.

Fibrosis in hepatitis C patients predicts complications after elective total joint arthroplasty.

Effects of Hepatitis C on total hip (THA) and total knee arthroplasty (TKA) outcomes are poorly understood. Seventy-two hepatitis C patients underwent 77 primary THA or TKA and were retrospectively identified, stratified by fibrosis and thrombocytopenia and compared to matched controls. Overall, Hepatitis C and control patients had similar outcomes. After TKA, fibrotic hepatitis C patients demonstrated a greater average hemoglobin drop than non-fibrotic hepatitis C patients (4.9 versus 3.8, P=0.023), greater deep infection rate (21% versus 0%, P=0.047), and rate of cellulitis (21% versus 0%, P=0.047). Thrombocytopenia showed a trend toward greater infections. Prior to fibrosis, Hepatitis C patients appear to be at no increased risk of complication after joint arthroplasty. Evaluation of fibrosis may predict poor outcome in Hepatitis C patients.
