Olecranon osteotomy vs. triceps-sparing for open reduction and internal fixation in treatment of distal humerus intercondylar fracture: a systematic review and meta-analysis.

ABSTRACT:

Background

The open reduction and internal fixation (ORIF) was a standard treatment approach for fracture at distal humerus intercondylar, whereas the optimal way before ORIF remains inconclusive. We, therefore, performed a systematic review and meta-analysis to assess the efficacy and safety of olecranon osteotomy vs. triceps-sparing approach for patients with distal humerus intercondylar fracture.

Methods

The electronic searches were systematically performed in PubMed, EmBase, Cochrane library, and Chinese National Knowledge Infrastructure from initial inception till December 2019. The primary endpoint was the incidence of excellent/good elbow function, and the secondary endpoints included Mayo elbow performance score, duration of operation, blood loss, and complications.

Results

Nine studies involving a total of 637 patients were selected for meta-analysis. There were no significant differences between olecranon osteotomy and triceps-sparing approach for the incidence of excellent/good elbow function (odds ratio [OR]: 1.37; 95% confidence interval [CI]: 0.69-2.75; P?=?0.371), Mayo elbow performance score (weight mean difference [WMD]: 0.17; 95% CI: -2.56 to 2.89; P?=?0.904), duration of operation (WMD: 4.04; 95% CI: -28.60 to 36.69; P?=?0.808), blood loss (WMD: 33.61; 95% CI: -18.35 to 85.58; P?=?0.205), and complications (OR: 1.93; 95% CI: 0.49-7.60; P?=?0.349). Sensitivity analyses found olecranon osteotomy might be associated with higher incidence of excellent/good elbow function, longer duration of operation, greater blood loss, and higher incidence of complications as compared with triceps-sparing approach.

Conclusions

This study found olecranon osteotomy did not yield additional benefit on the incidence of excellent/good elbow function, while the duration of operation, blood loss, and complications in patients treated with olecranon osteotomy might be inferior than triceps-sparing approach.

Project description:BackgroundDistal humerus fracture open reduction and internal fixation (ORIF) represents a substantial cost burden to the health care system. The purpose of this study was to describe surgical encounter cost variation for distal humerus ORIF, and to determine demographic-, injury-, and treatment-specific factors that influence cost.MethodsWe retrospectively identified adult patients (≥18 years) treated for isolated distal humerus fractures between July 2014 and July 2019 at a single tertiary academic referral center. For each case, surgical encounter total direct costs (SETDCs) were obtained via our institution's information technology value tools, which prospectively record granular direct cost data for every health care encounter. Costs were converted to 2019 dollars using the personal consumption expenditure indices for health and summarized with descriptive statistics. Univariate and multivariate linear regression models were used to identify factors influencing SETDC.ResultsSurgical costs varied widely for the 47 included patients, with a standard deviation (SD) of 33% and interquartile range of 76%-124% relative to the mean SETDC. Implant and facility costs were responsible for 46.2% and 32.6% of the SETDC, respectively. Implant costs also varied considerably, with an SD of 21% and range from 13%-36% relative to the mean SETDC. Multivariate analysis demonstrated that SETDC increased 24% (P < .001) on performing an olecranon osteotomy, and by 15% for each additional 1 hour of surgical time (P < .001). These findings were independent of age, sex, body mass index, open fracture, need for an additional small plate construct as a reduction aid, and fracture pattern (all insignificant in the multivariate analysis, with P >.05 for each factor).ConclusionSubstantial variations in surgical encounter total direct costs for distal humerus ORIF exist, as do wide variations in associated implant costs that comprise nearly half of the entire surgical cost. Performing an olecranon osteotomy, and increased surgical time, significantly increased surgical costs. Although use of an olecranon osteotomy may not be a completely controllable factor as it is confounded by fracture severity and operative time, this may suggest that surgeons should try to use an olecranon osteotomy judiciously. Although complexity of the fracture pattern was statistically insignificant, it is confounded by the need for an olecranon osteotomy and increased surgical time and likely is a clinically relevant and nonmodifiable driver of surgical cost. These findings highlight opportunities to reduce cost variation, and potentially improve the value of care, for distal humerus ORIF patients.

Project description:In the amyoplasia type of arthrogryposis, a reverse pronated grasp pattern is often seen. We hypothesized that repositioning the hands, through distal humerus external rotation osteotomies (DHO), would allow for palm-to-palm grasp without arm cross-over and would improve function and parent/patient satisfaction.The medical records of all patients treated surgically for arthrogryposis were reviewed at the Shriners Hospital for Children, St. Louis, MO. From 2012 to 2014, 9 patients (14 extremities) had undergone a DHO. All patients had preoperative and postoperative video recordings of functional activities and we assessed functional changes after osteotomies. Preoperative upper extremity position was graded as 1, palms facing midline; 2, palm facing posterior; and 3, palms facing away from midline. Postoperative Pediatric Outcomes Data Collection Instrument (PODCI) questionnaires were obtained and parent satisfaction was evaluated.Mean patient age at the time of surgery was 6.5 years. Five patients underwent bilateral DHOs. All patients had 3 or fewer additional procedures on an upper extremity during the study period. All patients had an improved resting posture of the upper extremity after DHO surgery, with a mean change of 51° (range, 15°-90°). Grasp pattern was altered in 13 extremities; there was a change in hand position of at least 1 grade and 5 had complete change from 3 to 1, palms facing away from midline to facing toward midline. There was a wide range in postoperative PODCI scores for function, but Happiness scores were high, mean 89 (range, 60-100). Parents universally stated the procedure improved the child's function "a great deal." There were 2 complications: 1 periprosthetic humerus facture with recurrence of the internal rotation and 1 patient with scarring of the triceps requiring tenolysis.The DHO is an effective procedure for correcting the internal rotation position of the upper extremity in arthrogryposis and the surgery improves hand opposition with minimal complications. Universally, there was perceived improved function with high postoperative PODCI Happiness scores.Therapeutic V.

Project description:BackgroundOpen reduction and plate fixation are the preferred treatment options for most distal humerus fractures in adults. However, it is often challenging for orthopedic surgeons because of the complex anatomy and the difficulty in achieving stable fixation. This multicenter study aimed to analyze the complication types and rates of patients with distal humerus fractures treated with open reduction and plate fixation, and compare the results with those found in the literature. In addition, we describe the clinical outcomes.MethodsThis retrospective multicenter study was conducted between September 2001 and March 2021 and included data from four hospitals. In total, 349 elbows underwent surgical treatment at these hospitals during the study period. Patients > 17 years of age who were treated by plate fixation were included, and patients who were treated by other fixation methods were excluded. A total of 170 patients were included in the study. The following types of complications were investigated: (1) nerve related; (2) fixation and instrument related; (3) osteosynthesis related; (4) infection; and (5) others.ResultsThe following complications were found: (1) 26 (15.3%) cases of postoperative ulnar nerve symptoms; 4 (2.4%) of postoperative radial nerve symptoms; (2) one (0.6%) case of screw joint penetration and screw loosening; and eight (4.7%) cases of hardware removal due to instrument skin irritation; (3) seven (4.1%) cases of nonunion; (4) two (1.2%) and four (2.2%) cases of superficial and deep infection, respectively, and seven (3.9%) cases of wound complication; and (5) 37 (21.8%) cases of heterotrophic ossification, 79 (46.5%) cases of elbow stiffness (did not achieve functional range of motion [ROM]), and 41 (24.1%) cases of osteoarthritis over Broberg and Morrey Grade I. Paradoxically, the postoperative ulnar nerve symptoms were more frequent in the prophylactic ulnar nerve anterior transposition group. However, this difference was not statistically significant (p = 0.086). The mean ROM was 123.5° flexion to 9.5° extension. The average Disabilities of the Arm, Shoulder and Hand (DASH) score was 14.5 ± 15.6.ConclusionsOpen reduction and plate fixation for distal humeral fractures is a reasonable treatment option with acceptable complication rates and favorable clinical outcomes. Surgeons must be vigilant about ulnar nerve complications. Level of Evidence Therapeutic Level III.

Project description:PurposeDistal 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.MethodsWe 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.ResultsOf 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.ConclusionsSubstantial 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 relevanceThis study identifies modifiable factors that may lead to cost reduction for distal radius ORIF.

Project description:BackgroundProximal humerus fractures treated in the face of ipsilateral injuries to the shoulder girdle may be predisposed to worse clinical outcomes.Questions/purposesThe purpose of this investigation was to examine outcomes of proximal humerus fractures treated with open reduction internal fixation (ORIF) using an endosteal augment in the presence of a concomitant shoulder girdle injury in comparison to isolated proximal humerus fractures treated with ORIF and endosteal augment.MethodsA prospective database was used to identify proximal humerus fractures with ipsilateral shoulder girdle injuries (glenohumeral and acromioclavicular dislocation, fractures of the acromion, clavicle, scapula, or humeral diaphysis). These were compared to isolated proximal humerus fractures treated in the same fashion (ORIF with endosteal augment). Minimum of 1 year follow-up was required for inclusion. Outcomes assessed included range of motion (ROM), development of avascular necrosis (AVN), hardware-related complications, reoperation, and subjective outcome assessments including the Disabilities of Arm Shoulder and Hand questionnaire (DASH), Constant score, UCLA rating scale, and the Short Form-36 (SF-36).ResultsFifteen ipsilateral injuries were seen in 14 patients. Seventy-seven isolated proximal humerus fractures were available for comparison. The ipsilateral injury group had significantly worse forward flexion (141 vs 156°, p = 0.02), external rotation (56 vs 64°, p = 0.03), higher rates of avascular necrosis (4 of 14, 28.6% vs 1 of 77, 1.3%, p = 0.002), and inferior SF-36 physical health scores (48.5 vs 63.5; p = .04). Despite these differences, no significant differences were seen with hardware-related complications or DASH, Constant score, or UCLA rating scale results. No patients required secondary reconstructive procedures.ConclusionDespite a statistically higher rate of AVN and decreased ROM, patient-based outcomes of proximal humerus fractures with ipsilateral shoulder injuries approached those seen in isolated proximal humerus fractures. This suggests that these injuries can achieve similarly good clinical results provided any associated shoulder pathology is identified and treated appropriately.

Project description:INTRODUCTION:In locked plate fixation of proximal humerus fractures, the calcar is an important anchor point for screws providing much-needed medial column support. Most locking plate implants utilize a fixed-trajectory locking screw to achieve this goal. Consequently, adjustments of plate location to account for patient-specific anatomy may result in a screw position outside of the calcar. To date, little is known about the consequences of "missing" the calcar during plate positioning. This study sought to characterize the biomechanics associated with proximal and distal placement of locking plates in a two-part fracture model. MATERIALS AND METHODS:This experiment was performed twice, first with elderly cadaveric specimens and again with osteoporotic sawbones. Two-part fractures were simulated and specimens were divided to represent proximal, neutral, and distal plate placements. Non-destructive torsional and axial compression tests were performed prior to an axial fatigue test and a ramp to failure. Torsional stiffness, axial stiffness, humeral head displacement and stiffness during fatigue testing, and ultimate load were compared between groups. RESULTS:Cadavers: Proximal implant placement led to trends of decreased mechanical properties, but there were no significant differences found between groups. Sawbones: Distal placement increased torsional stiffness in both directions (p?=?0.003, p?=?0.034) and axial stiffness (p?=?0.018) when compared to proximal placement. Distal placement also increased torsional stiffness in external rotation (p?=?0.020), increased axial stiffness (p?=?0.024), decreased humeral head displacement during fatigue testing, and increased stiffness during fatigue testing when compared to neutral placement. DISCUSSION:The distal and neutral groups had similar mechanical properties in many cadaveric comparisons while the proximal group trended towards decreased construct stiffness. RESULTS:from the Sawbones model were more definitive and provided further evidence that proximal calcar screw placements are undesirable and distal implant placement may provide improved construct stability. CONCLUSION:Successful proximal humerus fracture reconstruction is inherent upon anatomic fracture reduction coupled with medial column support. Results from this experiment suggest that missing the calcar proximally is deleterious to fixation strength, while it is safe, and perhaps even desirable, to aim slightly distal to the intended target.
