Background: We consider dual-plate fixation to improve construct rigidity in cases with fracture complexity. The purpose of this study is to compare the rate of nonunion, prognosis, and complications at 6–12 months for surgically treated acute mid-shaft clavicle fractures when extra-periosteal dual-plate fixation is used in place of the conventional single-plate fixation. Materials and Methods: The comparative study was conducted on 47 patients who received acute mid-shaft clavicular fracture treatment in our hospital from March 2015 to July 2018. All patients were divided into dual-plate fixation treatment (group A) and single-plate fixation (group B). Patients undergoing single-plate fixation were compared to dual-plate fixation. Patients were followed up for 6–12 months. Charts were reviewed to assess union rates, prognosis, and complications. Results: Forty-seven clavicles (30 single plates and 17 dual plates) were evaluated. All patients (100%) in dual plating group and 128 (93.3%) in single plating group obtained bony union by 1 year. When comparing groups at 3 months, radiographic union was present in 50.0% of single plates and 64.7% in the dual plating group ( p = 0.032). However, at 6 months, no significant difference existed (90.0% vs. 94.1%, p = 0.297). Comparing groups at 1.5 and 6 months, Constant–Murley outcome scores were present with no significant difference ( p = 0.129, p = 0.054) between single plates and dual plating group. However, at 3 months, significance difference existed. Discussion: Three months after the operation, patients with dual-plate fixation showed good functional recovery. Extra-periosteal dual plating for acute mid-shaft clavicle fractures can be safely considered for the treatment of complex acute mid-shaft clavicle fractures without increasing the risk of nonunion or revision. Conclusions: Open reduction and internal fixation with an extra-periosteal dual plating technique is a reliable option for treatment of acute mid-shaft clavicle fractures, especially in the setting of severely comminuted fractures and in situations where bone quality is questionable and additional fixation is desired.
Purpose: The study described a novel surgical treatment of Haraguchi type 1 posterior malleolar fracture in tri-malleolar fracture and patient outcomes at intermediate period follow-up. Methods: All patients from January 2015 to December 2017 with tri-malleolar fracture of which posterior malleolar fractures were Haraguchi type 1, were surgically treated in this prospective study. Lateral and medial malleolar fractures were managed by open reduction and internal fixation through dual incision approaches. 36 cases of Haraguchi type 1 posterior malleolar fractures were randomly performed by percutaneous posteroanterior screw fixation with the aid of medial exposure (group 1). And 40 cases were performed by percutaneous anteroposterior screw fixation (group 2). Clinical outcomes, radiographic outcomes and patient-reported outcomes were recorded. Results: Seventy-six patients with mean follow-up of 30 months were included. There were no significant differences in the mean operation time (81.0 ± 11.3 vs. 77.2 ± 12.4), ankle function at different periods of follow-up, range of motions and visual analog scale (VAS) at 24 months between the two groups ( p > 0.05). However, the rate of severe post-traumatic arthritis (Grade 2 and 3) and the rate of step-off rather than gap in radiological evaluation were lower in group 1 than that in group 2 ( p < 0.05). Conclusion: Using our surgical technique, more patients had good outcome with a lower rate of severe post-traumatic arthritis, compared with the group of percutaneous anteroposterior screw fixation. Percutaneous posteroanterior screw fixation can be a convenient and reliable alternative in treating Haraguchi type 1 posterior malleolar fracture.
Background. Osteoporotic thoracolumbar compression fractures have become a great social burden due to the aging tendency of population. This study is aimed at comparing the clinical and radiological outcomes of percutaneous kyphoplasty with or without pedicle screw fixation in patients with osteoporotic thoracolumbar fractures. Hypothesis. There is a difference in clinical outcomes between percutaneous kyphoplasty with pedicle screw fixation and percutaneous kyphoplasty. Methods. This retrospective study included 87 patients who received percutaneous kyphoplasty with or without pedicle screw fixation between October 2015 and October 2017 at Ningbo No.6 Hospital and were followed for 2 years. A total of 40 patients received percutaneous kyphoplasty with pedicle screw fixation (PKPF group), and the other 47 patients had percutaneous kyphoplasty only (PKP group). The outcomes were measured using the visual analogue scale (VAS), Oswestry Disability Index (ODI), Cobb angle (CA), and anterior vertebra height rate (AVHr), which were calculated at preoperative admission and each follow-up visit. Complications including postoperative back pain, refracture, and fixation failure were collected from medical records. Results. There was no significant difference in baseline characteristics or preoperative data between the two groups ( p < 0.05 ) but significantly better improvements in VAS, ODI, CA, and AVHr at 12- and 24-month follow-up visits in the PKPF group compared with those of the PKP group. 23 (48.9%) patients in the PKP group had complications, whereas only 5 (12.5%) patients in the PKPF group presented complications including 2 postoperative back pain and 1 fixation failure ( p = 0.04 ). Conclusions. PKPF obtained longer correction and better improvement in VAS, ODI, and CA in patients with osteoporotic thoracolumbar vertebral fractures than PKP.
Femoral intertrochanteric fracture is very common in elderly population. The usual treatment for these patients is intra-extramedullary fixation. In normal situations, expand medullary cavity is needed, in order to implant various intramedullary implants. On rare occasion, which will in turn lead to the reamer is stuck into the medullary cavity of femoral shaft. Open or closed technique for moving of the broken nails had been reported before. We firstly report a novel technique by using handy tool which included in orthopaedic instrument set to remove the broken reamer stuck into femoral cavity when implanting a PFNA.
Objective: Valgus-impacted femoral neck fractures with or without posterior tilt of the femoral head are very common and full of pitfalls in clinical practice, which may lead to femoral neck shortening (FNS) and avascular necrosis (AVN). The study tries to introduce a novel technical trick aiming at anatomical reduction of valgus-impacted femoral neck fracture with minimally invasive procedure, and summarize the clinical prognosis in case series. Methods:In this retrospective study, 24 patients (seven men and 17 women) with valgus-impacted femoral neck fractures between May 2017 and July 2020 were managed by "in-out-in" percutaneous reduction technique (percutaneous reduction group). Another 24 cases (10 men and 14 women) suffering the fractures underwent in situ fixation were enrolled as control group for function comparison (in situ fixation group). All patients were followed up for 24-42 months. The clinical outcomes included complications after operations (χ 2 test) and Harris Hip Score (HHS) for hip function (unpaired t test) in the two groups. The radiographic outcomes were evaluated by collodiaphyseal angle, posterior tilt angle, and FNS before the operation and during the follow-up in the percutaneous reduction group (unpaired t test).Results: Patients' preoperative data, including age, sex, affected side, fracture types, and medical history, were similar between the two groups, respectively (p > 0.05). After surgery, the mean HHS at 6, 12, and 24 months were all better in the percutaneous reduction group (76 AE 6.72, 85.34 AE 6.33 and 90.54 AE 5.81) than that in the in situ fixation group (70.86 AE 6.91, 80 AE 6.11 and 84.1 AE 7.82), respectively (p < 0.05). One patient suffered fixation failure with screws retreat and one patient suffered AVN in the percutaneous reduction group. In the in situ fixation group, AVN occurred in two patients at last follow-up. There was no significant difference in complication amounts between the two groups (p > 0.05). In the percutaneous reduction group, collodiaphyseal angle, posterior tilt angle, and amount of FNS were significantly different between preoperative cases and immediately postoperative cases (p < 0.05). However, there was no statistical difference of the measurements among postoperative cases at different time points (within 24 h, 6 months, and 2 years postoperatively) (p > 0.05).Conclusions: Our experience of the technique and the case series show that "in-out-in" percutaneous reduction technique for treatment of valgus-impacted femoral neck fracture with or without posterior tilt of the femoral head is safe and effective for achieving successful bone union and satisfactory function.
Objectives The objective of this study was to compare the results of two methods for sparing the pronator quadratus in volar plating of distal radius fractures. Methods A total of 110 patients were randomized to volar plating with sparing of the pronator quadratus either by a transverse incision along the distal border of the pronator quadratus (Group A, 55 people) or by the brachioradialis splitting method (Group B, 55 people). The operative and radiation time, range of motion, grip strength, Disabilities of the Arm, Shoulder, and Hand (DASH) scores, Visual Analog Scale (VAS) scores, and complications were recorded. Results There were no significant differences in the mean operative time, radiation time, mean bone union time, or total complication rate between the groups. We found no significant differences in range of motion, grip strength, VAS scores, and DASH scores at any of the study intervals between the groups. Although neurapraxia of the superficial branch of the radial nerve was more common in Group B than in Group A (6.7% vs. 0%), the difference was not significant. Conclusions Both methods were efficient approaches for sparing the pronator quadratus and had similar clinical outcomes, but they had different indications.
Background:There are few posterolateral approaches that do not require the common peroneal nerve (CPN) dissection. With the nerve exposure, it would pose a great challenge and sometimes iatrogenic damage over the surgical course. The purpose was to present a case series of patients with posterolateral tibial plateau fractures treated by direct exposure and plate fixation through a modified posterolateral approach without exposing the common peroneal nerve (CPN).Materials and Methods:9 consecutive cases of isolated posterior fractures of the posterolateral tibial plateau were operated by open reduction and plate fixation through the modified posterolateral approach without exposing the CPN between June 2009 and January 2012. Articular reduction quality was assessment according to the immediate postoperative radiographs. At 24 month followup, all patients had radiographs and were asked to complete a validated outcome measure and the modified Hospital for Special Surgery (HSS) Knee Scale.Results:All patients were followedup, with a mean period of 29 months (range 25–40 months). Bony union was achieved in all patients. In six cases, the reduction was graded as best and in three cases the reduction was graded as middle according to the immediate postoperative radiographs by the rank order system. The average range of motion arc was 127° (range 110°–134°) and the mean postoperative HSS was 93 (range 85–97) at 24 months followup. None of the patients sustained neurovascular complication.Conclusions:The modified posterolateral approach through a long skin incision without exposing the CPN could help to expand the surgical options for an optimal treatment of this kind of fracture, and plating of posterolateral tibial plateau fractures would result in restoration and maintenance of alignment. This approach demands precise knowledge of the anatomic structures of this region.
