RESUMEN
BACKGROUND: Metacarpal fractures are common injuries with multiple options for fixation. Our purpose was to compare outcomes in metacarpal fractures treated with intramedullary screw fixation (IMF), Kirschner wires (K-wires), or plating. METHODS: A systematic literature review using the MEDLINE database was performed for studies investigating metacarpal fractures treated with IMF, plating, or K-wires. We identified 34 studies (9 IMF, 8 plating, 17 K-wires). A meta-analysis using both mixed and fixed effects models was performed. Outcome measures included mean Disabilities of the Arm, Shoulder, and Hand (DASH) scores, total active motion (TAM), grip strength, time to radiographic healing, and rates of infection and reoperation. RESULTS: Patients with IMF had significantly lower DASH scores (0.6 [95% confidence interval [CI], 0.2-1.0]) compared with K-wires (7.4 [4.8-9.9]) and plating (9.8 [5.3-14.3]). Intramedullary screw fixation also had significantly lower rates of reoperation (4%, [2%-7%]), compared with K-wires (11% [7%-16%]) and plating (11% [0.07-0.17]). Grip strength was significantly higher in IMF (104.4% [97.0-111.8]) compared with K-wires (88.5%, [88.3-88.7]) and plating (90.3%, [85.4-95.2]). Mean odds ratio time was similar between IMF (21.0 minutes [10.4-31.6]) and K-wires (20.8 minutes [14.0-27.6]), but both were shorter compared with plating (52.6 minutes [33.1-72.1]). There were no statistically significant differences in time to radiographic healing, TAM, or rates of reoperation or infection. CONCLUSIONS: This meta-analysis compared the outcomes of metacarpal fixation with IMF, K-wires, or plating. Intramedullary screw fixation provided statistically significant lower DASH scores, higher grip strength, and lower rates of reoperation, suggesting that it is a comparable method of fixation to K-wires and plating for metacarpal fractures.
RESUMEN
BACKGROUND: Patient expectations influence patient-reported outcomes after musculoskeletal injuries. The goal of this study is to determine how pretreatment expectations correlate with outcomes in patients with distal radius fractures. METHODS: Seventy-five patients with an isolated distal radius fracture were prospectively enrolled into nonoperative and operative cohorts. The Trauma Expectation Factor-Trauma Outcome Measure (TEF-TOM) score was the primary outcome measure. Trauma Expectation Factor scores were recorded at the time of enrollment, and TOM scores were recorded at 3, 6, and 12 months. Quick Disabilities of the Arm, Shoulder, and Hand (qDASH) and Patient-Rated Wrist Evaluation (PRWE) scores were also recorded. RESULTS: Trauma Outcome Measure scores at all time points were worse than expected (P < .01). Expectations were higher for patients younger than 65 years than for the 65+ group (P = .02). In patients aged 65+ years, mean TOM at 3 months was not significantly different than expected (P = .11) but decreased by 6 (P = .04) and 12 months (P < .01). Baseline TEF and TEF-TOM scores were not significantly different between operative and nonoperative groups (P = .37). Quick Disabilities of the Arm, Shoulder, and Hand and PRWE scores were not significantly different between age or treatment groups at the final follow-up. CONCLUSIONS: The overall treatment of distal radial injuries in our study did not meet patient expectations. Patients aged 65 years or older had lower expectations but were not able to predict their outcomes better than patients aged <65 years. There were no differences in TEF or TOM by treatment method. Patients demonstrated improved functional outcomes (qDASH/PRWE) at all time points regardless of age and treatment method.
RESUMEN
Distal radius fractures are the most common upper extremity fracture and volar locking plate fixation has become a common modality for operative management of these injuries over the last 2 decades. However, despite the widespread use of volar locking plates, there remains no comprehensive guide detailing the available reduction techniques using these systems. This review aims to consolidate the reduction techniques from the literature along with the authors' experiences into a blueprint for distal radius fracture reduction when using a volar plate. Techniques described include those with and without use of the plate and with supplementary means of fixation for both extra-articular and intra-articular fracture patterns.
