Dorsal Plating for Intra-articular Middle Phalangeal Base Fractures With Volar Instability.

ABSTRACT: Background: Intra-articular middle phalangeal base fractures with volar instability are rare injuries with scant literature on optimal management. Our purpose is to describe our method of dorsal plating and report postoperative outcomes. Methods: This study is a retrospective case review of 5 patients with intra-articular middle phalangeal base fractures with volar proximal interphalangeal joint instability, measuring subjective, clinical, and radiographic outcomes. Results: Patient age averaged 38.2 years (range, 23-56 years), and 80% were male. Sporting injuries were the most common mechanism (80%). Time to surgery averaged 7 days, and postoperative follow-up duration averaged 19.6 months (median 8 months). All fractures were intra-articular at the proximal interphalangeal joint with volar instability. There were no complications and no patients required secondary surgery. Grip strength was maintained and range of motion was good, based on the American Society for Surgery of the Hand Total Active Motion score. Average Quick Disability of the Arm, Shoulder and Hand was 0.5 (range, 0-2.3), 100% of patients were satisfied, and average visual analog pain score was 1.2. Patients returned to work at a median of 4 days. There was radiographic union at an average of 6.6 weeks (range, 6-7 weeks) in all fractures. Conclusions: Dorsal plating using a 1.5-mm modular hand plate is a viable option for rigid fixation of intra-articular middle phalangeal base fractures with volar instability. This fixation method allows for early range of motion without complications in this case series. All fractures united, and patients had minimal functional deficits and were able to maintain good range of motion.

Project description:BackgroundThe most commonly used approach for distal radius fractures is the traditional Henry approach. However, it requires an intraoperative incision of the pronator quadratus (PQ) muscle, which results in a series of complications if the repair of the PQ fails.AimThe objective of this study was to investigate the efficacy of sparing the pronator quadratus for volar plating of the distal radius fractures.MethodsSeventy-six patients who suffered from distal radius fractures of types 23-B, 23-C1, and 23-C2 as per the AO Foundation and Orthopaedic Trauma Association (AO/OTA) classification were treated with volar locking plate fixation using either the PQ muscle incision and repair (group A, n = 39) or the PQ muscle preservation approach (group B, n = 37). Intraoperative index, postoperative efficacy and complications of patients were recorded and evaluated.ResultsAll patients were followed up for more than one year after surgery. All fractures achieved union. There were significant differences in mean operative time, mean intraoperative blood loss, and mean fracture healing time between the two groups. Still, there were no significant differences in limb function scores between the two groups at the 12-month postoperative follow-up. Outcomes assessed at 1 week, 1 month, and 3 months after surgery demonstrated significant differences in the mean range of motion and pain-related visual analog scale (VAS) between the two groups. As the range of motion and grip strength increased, the VAS scores decreased, and there was no significant difference between the two groups at 12 months postoperatively. Although tendon irritation and delayed carpal tunnel syndrome were more common in group A than in group B (7.6% vs. 0% and 5.1% vs. 0%, respectively), the differences were not statistically significant.ConclusionThe modified Henry approach with sparing pronator quadratus muscle has no significant advantage in the range of wrist motion and upper limb function in the late stage. Nevertheless, the intraoperative placement of the plate under the pronator quadratus muscle can shorten the operation time, reduce intraoperative bleeding, reduce early postoperative pain, promote early activity, and improve the patient's quality of life. It is recommended that the pronator be preserved at the time of surgery.

Project description:BACKGROUND:Distal radius fracture (DRF) is the most common upper extremity fracture that requires surgery. Operative treatment with a volar locking plate has proved to be the treatment of choice for unstable fractures. However, no consensus has been reached about the benefits of pronator quadratus (PQ) repair after volar plate fixation of DRF in terms of patient-reported outcome measures, pronation strength, and wrist mobility. METHODS:We searched the PubMed, Embase, Cochrane Central, and China National Knowledge Infrastructure (CNKI) databases up to March 13, 2020, and included randomized-controlled, non-randomized controlled, or case-control cohort studies that compared cases with and without PQ repair after volar plate fixation of DRF. We used a random-effects model to pool effect sizes, which were expressed as standardized mean differences (SMDs) and 95% confidence intervals. The primary outcomes included Disabilities of the Arm, Shoulder, and Hand scores and pronation strength. The secondary outcomes included the SMDs in pain scale score, wrist mobility, and grip strength. The outcomes measured were assessed for publication bias by using a funnel plot and the Egger regression test. RESULTS:Five randomized controlled studies and six retrospective case-control studies were included in the meta-analysis. We found no significant difference in primary and secondary outcomes at a minimum of 6-month follow-up. In a subgroup analysis, the pronation strength in the PQ repair group for AO type B DRFs (SMD = - 0.94; 95% CI, - 1.54 to - 0.34; p < 0.01) favored PQ repair, whereas that in the PQ repair group for non-AO type B DRFs (SMD = 0.39; 95% CI, 0.07-0.70; p = 0.02) favored no PQ repair. DISCUSSION:We found no functional benefit of PQ repair after volar plate fixation of DRF on the basis of the present evidence. However, PQ muscle repair showed different effects on pronation strength in different groups of DRFs. Future studies are needed to confirm the relationship between PQ repair and pronation strength among different patterns of DRF. REGISTRATION:This study was registered in the PROSPERO registry under registration ID No. CRD42020188343 . LEVEL OF EVIDENCE:Therapeutic III.
