A hybrid technique combining intramedullary pinning with extramedullary plate fixation in unstable and comminuted radial head fractures following on-table reconstruction.

BACKGROUND: Management of comminuted radial fractures remains controversial. Currently, the emergence of on-table reconstruction technique has made fixation in comminuted radial head fractures more viable. However, the present study reported an intro-operative unstable displacement from the reconstructed radial head to the neck during plate fixation, characterized by a poor radiocapitellar contact and incongruity between the radial head and neck. A hybrid technique combining with intramedullary pining was performed in our study to restore the normal alignment and maintain the stability of fixation. Therefore, the purpose of this article aimed to prove the feasibility of unstable comminuted radial head fractures treated with the extramedullary plate and intramedullary pinning fixation using titanium elastic nails. METHODS: The clinical, functional and radiographic outcomes of the groups were compared during follow-up. The radiographic examination was conducted to evaluate the status of bone union, heterotopic ossification and post-traumatic arthritis. The functional assessment was performed to evaluate clinical effects, which included measurements of range of motion (ROM) in the elbow, Visual Analog Scale (VAS) score, Elbow Self-Assessment score (ESAS), Mayo Elbow Performance score (MEPS), and Disabilities of the Arm, Shoulder, and Hand (DASH)Outcome Measure score. RESULTS: Thirteen patients with unstable fractures were participated with an average follow-up of (38.6 ± 4.5) months for the experimental group and (32.0 ± 6.3) months for the control group, respectively. The functional outcomes in the experimental group, including MEPS and DASH, were significantly superior to the control group. However, no significant difference was observed in the elbow ROM and VAS score between two groups. In the last follow-up, one patient with post-traumatic arthritis rated as grades 1 and two with heterotopic ossifications were observed in the experimental group. In the control group, degenerative changes were observed in three cases (grade 1 in two cases and grade 2 in one case) and heterotopic ossifications rated as grade I were found in two patients. CONCLUSION: Collectively, intramedullary pinning with extramedullary plate fixation is feasible in unstable comminuted radial head fractures, which can be considered as a remedial surgery for on-table reconstruction technique.

Management of Open Calcaneal Fractures with Medial Wounds by One-Stage Sequential Reduction and Frame Structure Fixation Using Percutaneous Kirschner Wires.

OBJECTIVE: To assess the clinical outcomes of open calcaneal fractures with medial wounds treated with one-stage management, including early modern wound care, sequential reduction, and frame structure fixation using percutaneous Kirschner wires. METHODS: A total of 19 patients with open calcaneal fractures admitted to our hospital from May 2016 to March 2019 were selected in this study. Twelve type-II and seven type-IIIA medial open injuries were identified according to the classification of Gustilo and Anderson. Fractures were stratified by Sanders classification, including nine type-II fractures, seven type-III fractures, and three type-IV fractures. All patients accepted one-stage irrigation and debridement, sequential reduction of calcaneal fractures through the open medial wound, percutaneous Kirschner wire fixation, and primary closure of wounds covered with vacuum-assisted closure (VAC) device. The Bohler angle, the Gissane angle, and the width of the calcaneus were compared before and after surgery. The functional results were evaluated according to the Paley and Hall score system, visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score, Maryland Foot Score, and related complications. RESULTS: The follow-up duration for all patients ranged from 14 to 28 months (mean, 22.7 months). The angle of Bohler and Giasane was increased from (-7.6° ± 15.0°) and (96.6° ± 7.6°) before surgery to (23.7° ± 6.1°) and (124.1° ± 7.1°) postoperatively (P < 0.05), respectively. Three cases of superficial infection and two cases of wound dehiscence were observed in our study, which were then successfully treated with wound debridement, VAC replacement, appropriate use of antibiotics, and delayed closure. The last follow-up revealed three cases of lateral wall expansion and six cases of mild-to-moderate subtalar arthritis based on the Paley and Hall scoring system. According to the AOFAS ankle and hindfoot score, one case showed excellent results, 14 cases exhibited good results, and four cases displayed fair results, with the mean of 80.7 ± 6.7 points (range, 70-90). The Maryland Foot Score revealed one case of excellent outcomes, nine cases of good outcomes, and nine cases of fair outcomes with an average of 76.8 ± 8.6 points (range, 62-90). The mean VAS for pain was 1.8 ± 1.5 (range, 0-5), and a total of 14 patients complained of mild-to-moderate pain when walking for a more extended period. Severe complications, such as deep infection, osteomyelitis, and soft tissue necrosis, were not observed during follow-up. CONCLUSIONS: Collectively, one-stage management allowed the direct restoration of calcaneal morphology with a minimal invasion of soft tissues in most open calcaneal fractures with medial wounds, and the functional outcomes were comparable to previous data.
