Antegrade intramedullary fixation for adolescent fifth metacarpal neck fracture and its impact on epiphyseal growth.

ABSTRACT:

Background

Antegrade intramedullary nailing (AIMN) with Kirschner wire (K-wire) is a minimally invasive osteosynthesis technique. This procedure has been widely performed to treat the fifth metacarpal neck fracture (FMNF) in adults. This study was performed to determine whether using AIMN with a single K-wire to treat FMNF in adolescents would have good clinical and radiographic outcomes.

Methods

In this retrospective study, 21 children (aged 11-16 years) with FMNF were treated using AIMN with a single K-wire from May 2017 to January 2020 in our hospital. Indications for intervention were severe displacement with malrotation deformity, apex dorsal angulation of greater than 40°, or both. Collected data included apex dorsal angulation, range of motion (ROM) in the fifth metacarpophalangeal (MCP) joint, Visual Analog Scale (VAS) for pain, grip strength, and Disabilities of the Arm, Shoulder, and Hand (DASH) score.

Results

All patients were followed up for 12-24 months (average, 16.57 months), and all patients obtained anatomical reduction postoperatively. The healing time was 2.69 ± 0.83 months (range, 2-4 months). Average apex dorsal angulation was reduced significantly from 44.49°±2.64° to 15.74°±2.47° (P < 0.001). The average ROM in the MCP joint and apex dorsal angulation of the injured side were not significantly different from those of the uninjured side. The average DASH score was 1.76 ± 1.48 (range, 0-4), the mean VAS was 0.19 ± 0.60 (range, 0-2), and the mean grip strength was 91.55 %±4.52 % (range, 85-101 %). No secondary displacement, dysfunction, nonunion, infection, or osteonecrosis was observed during the follow-up. Although premature epiphyseal closure was found in one patient, no long-term clinical finding of angulation or shortening was identified.

Conclusions

Antegrade intramedullary fixation with single K-wire was an effective and reliable technique that successfully resulted in good functional and cosmetic outcomes for treating adolescents with FMNF. The impact on the growth plate was low in this population given that most patients were at or approaching skeletal maturity.

Project description:BackgroundThere is no consensus regarding the surgical treatment of humeral shaft fracture. The present meta-analysis was performed to compare the efficacy and safety between antegrade intramedullary nailing (IMN) and plating for humeral shaft fracture.MethodsPubMed, MEDLINE, Cochrane Library, EMBASE, Clinical Trails, Ovid, ISI Web of Science, and Chinese databases including WanFang Data, China National Knowledge Infrastructure were searched through March 10, 2019. The Review Manager software was adapted to perform statistical analysis and relative risk (RR) were used for the binary variables, and weighted mean difference and standardized mean difference (SMD) were used to measure the continuous variables. Each variable included its 95% confidence interval (CI).ResultsA total of 15 trials with 839 patients were included in the analysis. There was significant difference between IMN group and plate group in blood loss (SMD = 3.49, 95% CI: 1.19, 5.79, P = .003) and postoperative infections (RR = 3.04, 95% CI: 1.49, 6.24, P = .002). Additionally, significant difference was observed between minimally invasive plate osteosynthesis (MIPO) group and IMN group in nonunion rate (RR = 3.20, 95% CI: 0.12, 0.84, P = .02). Statistical significance was also observed between the open reduction plate fixation group and IMN group in restriction of shoulder and elbow joints results (RR = 0.49, 95% CI: 0.26, 0.96, P < .05). No significant difference was observed for the operation time, American Shoulder and Elbow Surgeons score, nerve injury, delayed union, reoperation in either group.ConclusionIMN may be superior to plate in reducing blood loss and postoperative infections for the treatment of humeral shaft fracture. However, MIPO was superior to IMN group in nonunion and equal to IMN in other parameters. Further research is required and future studies should include analysis of assessments at different stages and follow-up after removal of the implants.
