Project description:BackgroundLateral humeral condyle fractures are the second most common elbow fracture in children. Displaced and rotated fractures require stabilization and reduction. Kirschner wires (K-wires) are most commonly used in the fixation of these fractures. Here, we introduce a new fixation method that uses an absorbable screw. We aim to determine if it is feasible to treat lateral humeral condyle fractures with an absorbable screw by comparing functional outcomes following absorbable screw fixation vs. K-wire fixation.MethodsBetween May 2007 and September 2010, 86 patients were treated with absorbable screws (43 patients) or K-wire (43 patients). All patients had been diagnosed with lateral condyle fractures that were classified as either Jacob type II (unstable) or III. One absorbable screw (3.5 mm-diameter) was used for fixation in 1 group, while two 1.6 to 1.8 mm K-wires were used in the other group. Patients were followed 6 months about the elbow function according to Broberg and Morrey standard. On 5-7 years, the patients were followed about the carrying angle (valgus deformities and varus deformities), range of motion (flexion loss and extension loss), prominent lateral condyle, symptomatic implants, and fishtail deformity.ResultsAnatomic reduction was achieved in all patients. Each group had one radial nerve injury that were present preoperatively. Nerve function recovered spontaneously within 3 to 4 weeks of surgery in both patients. No patient developed necrosis of the capitulum in both groups. Nine patients in K-wires group and 2 in absorbable screw group developed symptomatic implants (P = .048). On the sixth month, there was no significant difference on elbow function according to Broberg and Morrey standard. On 5 to 7 years (average, 6.7 ± 1.3 years), valgus deformities was 6.8 ± 1.2 vs 5.7 ± 0.8, varus deformities was 7.2 ± 1.5 vs 5.1 ± 1.9, flexion loss was 12.4 ± 2.2 vs 9.5 ± 3.1, extension loss was 11.1 ± 3.1 vs 10.2 ± 2.7, prominent lateral condyle was 27.9% vs 37.2%, fishtail deformity was 7.3% vs 4.9%, no significant difference between these groups.ConclusionsOpen reduction with absorbable screw fixation is feasible and safe for the treatment of lateral condyle fractures of the humerus in children.Level of evidenceTherapeutic III.

Project description:Proximal humeral fractures are common injuries with increasing incidence, particularly in the aging population. Nondisplaced or minimally displaced fractures can be treated conservatively whereas surgical fixation is usually indicated in the cases of displaced fractures. Various surgical options have been used for treatment of these fractures. Good outcomes have been reported with use of the Proximal Humeral Internal Locking System (PHILOS plate; Synthes, Zuchwil, Switzerland) as the implant of choice. However many complications have been reported, including varus malalignment, excessive retroversion of the articular part of the humerus, penetration of screws, and avascular necrosis of the humeral head. Therefore, we have hypothesized that an inadequate intraoperative fluoroscopic assessment may be an important factor contributing to these complications. We have described a step-by-step intraoperative fluoroscopic setup, including the proposal of a plate and screw view, focusing on the accuracy of reduction and proper placement of the PHILOS plate to prevent the complications previously described.

Project description:The proximal humeral locking plate (PHLP) is a recently developed fixed-angle implant that is an option for open reduction-internal fixation of an unstable displaced proximal humeral fracture. Various articles have reported successful outcomes using the PHLP when compared with other implant designs. However, many complications still occur with use of the PHLP, such as avascular necrosis of the humeral articular fragment, malreduction (particularly varus malalignment), and screw penetration. These complications are related to the difficulty in fixation of this particular type of fracture, as well as ineffective surgical technique. We have therefore proposed a step-by-step surgical technique for open reduction-internal fixation of an unstable displaced 3-part proximal humeral fracture using a PHLP. This technique focuses on the precise placement of the PHLP according to the plate design, as well as an effective intraoperative assessment, to improve surgical outcomes and prevent the various complications of proximal humeral fractures.

Project description:Distal clavicle fractures are common, and no standard treatment exists. Many different surgical modalities exist. This report describes an open reduction internal fixation technique that achieves both plate and coracoclavicular stabilization using a button device. A precontoured superior-lateral plate is secured to the clavicle. A 3.2-mm spade-tipped drill bit is drilled across the clavicle and coracoid, passing through 4 cortices. The button is loaded onto an insertion device, passed across the 4 cortices, and captured on the undersurface of the coracoid under fluoroscopic guidance. This construct is linked to the distal clavicle plate by heavy sutures using a second button that sits in the plate. The lateral locking holes are then filled to finalize fixation. This technique provides for a simplified way to achieve coracoclavicular stabilization when using a plate for fixation of distal clavicle fractures.

Project description:Introduction The ability to treat fracture with open reduction and internal fixation (OR/IF) has dramatically revolutionized the approach to mandible fracture. With OR/IF, the postoperative role of rigid maxillomandibular fixation (MMF) has declined, but it is used to maintain proper occlusion until internal fixation of the fracture is achieved. Objective To assess intraoperative manual MMF during OR/IF of selected cases of mandibular fractures. Methods This prospective study was conducted on 80 patients with isolated mandibular fractures managed by OR/IF using two titanium miniplates. The patients were classified into two groups: a control group (40 patients) treated by OR/IF after intraoperative rigid MMF followed by immediate MMF removal, and a study group (40 patients) treated by rigid MMF, which was replaced by temporary intraoperative manual MMF (3MF) until plate fixation. Results There were no significant differences of the postoperative complication and dental occlusion, although a highly significant reduction of operative time was achieved in the 3MF group. Patient who received the 3MF technique had statistically significantly better average intrinsic vertical mouth opening in the early postoperative period (1 week after surgery), and normal mouth opening could be achieved in all cases in both groups 8 weeks after surgery. Conclusions Intraoperative rigid MMF is not mandatory and can be replaced in selected cases of fracture mandible by manual maintenance of proper dental occlusion until hardware fixation, gaining the advantages of shorter operative time and less risk of blood-transmitted diseases to the surgical team and the patient in addition to the benefits of immediate postoperative mandible mobilization.

Project description:PurposeDetermining the magnitude of displacement in pediatric lateral humeral condyle fractures can be difficult. The purpose of this study was to (1) assess the effect of forearm rotation on true fracture displacement using a cadaver model and to (2) determine the accuracy of radiographic measurements of the fracture gap.MethodsA non-displaced fracture was created in three human cadaveric arms. The specimens were mounted on a custom apparatus allowing forearm rotation with the humerus fixed. First, the effect of pure rotation on fracture displacement was simulated by rotating the forearm from supination to pronation about the central axis of the forearm, to isolate the effects of muscle pull. Then, the clinical condition of obtaining a lateral oblique radiograph was simulated by rotating the forearm about the medial aspect of the forearm. Fracture displacements were measured using a motion-capture system (true-displacement) and clinical radiographs (apparent-displacement).ResultsDuring pure rotation of the forearm, there were no significant differences in fracture displacement between supination and pronation, with changes in displacement of <1.0 mm. During rotation about the medial aspect of the forearm, there was a significant difference in true displacements between supination and pronation at the posterior edge (p < 0.05).ConclusionOverall, true fracture displacement measurements were larger than apparent radiographic displacement measurements, with differences from 1.6 to 6.0 mm, suggesting that the current clinical methods may not be sensitive enough to detect a displacement of 2.0 mm, especially when positioning the upper extremity for an internal oblique lateral radiograph.

Project description:BackgroundThis study aimed to explore the clinical efficacy of treating a first metacarpal base fracture by closed reduction and percutaneous parallel K-wire interlocking fixation between the first and second metacarpals.MethodsTwenty patients treated by the abovementioned modified technique (modified technique group) and ten patients treated by the traditional percutaneous K-wire fixation technique (traditional technique group) from October 2015 to November 2019 at our institution were retrospectively reviewed. The patients' average age was 38 years (range, 16-61 years). The mean follow-up period was 13 months (range, 10-18 months). At the final follow-up, the functional recovery of the injured hand was assessed and compared between the modified and traditional technique groups. In addition, the functional recovery of the injured hand was compared with that of the uninjured hand within the modified technique group.ResultsAll patients recovered well, with no cases of infection or nonunion. Compared with the traditional technique group, the modified technique group had a shorter operative time, lower postoperative visual analogue scale pain score, better effective range of motion score of the first carpometacarpal joint (Kapandji score), and had almost no need for auxiliary plaster fixation, enabling functional exercise to be started earlier. Within the modified technique group, the mean hand grip strength, pinch strength, and Kapandji score on the injured side did not significantly differ to the values on the uninjured side in both the extra-articular and intra-articular fracture subgroups. While the abduction and flexion-extension arcs of the thumb on the injured hand were significantly smaller than those on the uninjured hand in both the extra-articular and intra-articular fracture subgroups, the patients felt clinically well with respect to daily activities and strength.ConclusionThe percutaneous parallel K-wire and interlocking fixation technique is simple, effective, and economical for first metacarpal base fractures.

Project description:Neglected fractures of the lateral humeral condyle (LHC) are misdiagnosed or insufficiently treated fractures, presenting later than 3 weeks after injury. The management of neglected LHC fractures in children remains controversial. Twenty-seven children were included in this retrospective study. Charts and medical records were investigated for demographics, time interval between injury and treatment, and type of treatment. Baseline radiographs were assessed for fracture grading and displacement. Final radiographs were investigated for bone healing, avascular necrosis, elbow deformities and growth disturbances. Complications were classified by the Clavien-Dindo-Sink (CDS) system. Outcomes were assessed according to the Dhillon Score (DhiS) and Mayo Elbow Performance Score (MEPS). The mean time from injury to presentation was 27 months. Treatments included nonoperative management (6 patients), "in-situ" fixation (7 patients), open reduction and internal fixation (11 patients) and corrective osteotomy (3 patients). The mean follow-up was 7 years (range: 2-16). Overall, we observed complications in 16 patients (59%); six complications were considered major (22%) and occurred in Weiss Grade 3 fractures, with lateral displacement ≥5 mm. At the latest follow-up, pain and functional scores improved in 23 of 27 patients (85%). Mean MEPS increased from an average of 62 points preoperatively to 98 points postoperatively, while mean DhiS improved on average from 5 to 8 points. CDS score and time interval between injury and treatment were independent predictors of MEPS and DhiS. Our study describes outcomes from a cohort of children undergoing different treatments for neglected LHC fractures. Prolonged time interval between injury and treatment and perioperative major complications negatively impacted the treatment outcomes. Our findings strengthen the requirement for widely agreed guidelines of surgical management in neglected LHC fractures.

Project description:Fractures of the lateral process of the talus (LPT) are relatively rare. We describe arthroscopic reduction and internal fixation for a type I fracture of the LPT according to the Hawkins classification. Preoperative computed tomography is necessary to evaluate the type and displacement of the LPT fracture because this type of fracture is often overlooked on a plain radiograph. The ankle is approached through a standard medial portal as the working portal and an anterolateral portal as the viewing portal. A 2.7-mm-diameter 30° arthroscope is used. Hematoma and soft tissues around the talus are cleared with a motorized shaver, and the anterior and lateral aspects of the talar process are visualized. Fracture reduction is obtained by pushing the lateral fragment of the lateral process medially and is fixed temporally with a 1.1-mm guidewire from the medial portal under both arthroscopy and fluoroscopy. A headless compression screw is inserted through the guidewire. Arthroscopic reduction and internal fixation for a type I LPT fracture can be easily accomplished, and return to daily and sports activities can be achieved in a relatively short time.

Project description:PURPOSE:Distal radius fracture open reduction and internal fixation (ORIF) represents a considerable cost burden to the health care system. We aimed to elucidate demographic-, injury-, and treatment-specific factors influencing surgical encounter costs for distal radius ORIF. METHODS:We retrospectively reviewed adult patients treated with isolated distal radius ORIF between November 2014 and October 2016 at a single tertiary academic medical center. Using our institution's information technology value tools-which allow for comprehensive payment and cost data collection and analysis on an item-level basis-we determined relative costs (RC) for each factor potentially influencing total direct costs (TDC) for distal radius ORIF using univariate and multivariable gamma regression analyses. RESULTS:Of the included 108 patients, implants and facility utilization costs were responsible for 48.3% and 37.9% of TDC, respectively. Factors associated with increased TDC include plate manufacturer (RC 1.52 for the most vs least expensive manufacturer), number of screws (RC 1.03 per screw) and distal radius plates used (RC 1.67 per additional plate), surgery setting (RC 1.32 for main hospital vs ambulatory surgery center), treating service (RC 1.40 for trauma vs hand surgeons), and surgical time (RC 1.04 for every 10 min of additional surgical time). Open fracture was associated with increased costs (RC 1.55 vs closed fracture), whereas other estimates of fracture severity were nonsignificant. In the multivariable model controlling for injury-specific factors, variables including implant manufacturer, and number of distal radius plates and screws used, remained as significant drivers of TDC. CONCLUSIONS:Substantial variations in surgical direct costs for distal radius ORIF exist, and implant choice is the predominant driver. Cost reductions may be expected through judicious use of additional plates and screws, if hospital systems use bargaining power to reduce implant costs, and by efficiently completing surgeries. CLINICAL RELEVANCE:This study identifies modifiable factors that may lead to cost reduction for distal radius ORIF.
