Elbow contracture following operative fixation of fractures about the elbow.

ABSTRACT: Background:The rates of elbow contracture and contracture release after surgically treated elbow trauma are poorly defined. The purpose of this study was to define the incidence of elbow contracture diagnosis and release after surgical treatment for elbow trauma. Methods:The Humana insurance database was queried using the PearlDiver Patient Records Database between 2007 and 2017. Subjects were identified using International Classification of Diseases (ICD) codes in combination with Current Procedural Terminology codes and were included if they had a minimum of 1-year follow-up. Qualifying operative elbow trauma patients were queried for development of postoperative elbow contracture. Patient demographic characteristics, risk factors for elbow stiffness, and use of postoperative anticoagulation were recorded. Fracture severity was classified based on ICD-9 and ICD-10 codes. Logistic multivariate analysis was performed to determine independent risk factors for postoperative elbow contracture. Results:The study population included 10,672 patients who were surgically treated for elbow trauma. In total, 902 patients (8.4%) were diagnosed with a contracture following fracture. Of patients with a diagnosis of elbow contracture, 65 patients (7.2%) underwent contracture release. On average, time to contracture diagnosis was 3.6 months (SD 7 months) and time to contracture release was 8.4 months (SD 3.6 months). The use of postoperative anticoagulation, burn or head injury at the time of fracture, male sex, obesity, opioid use, and moderate or severe fracture severity were significantly associated with progression to elbow contracture. Conclusion:The development of elbow contracture after surgical treatment of elbow trauma has a relatively high incidence of 8.4%.

Project description:BackgroundSimple elbow dislocation occurs at an incidence of 2.9 to 5.21 dislocations per 100,000 person-years, with as many as 62% of these patients experiencing long-term elbow joint contracture, stiffness, and/or pain. Poor outcomes and the need for secondary surgical intervention can often be prevented nonoperatively with early or immediate active mobilization and physical therapy. However, immobilization or limited mobilization may be necessary following trauma, and it is unknown how different periods of immobilization affect pathological changes in elbow joint tissue and how these changes relate to range of motion (ROM). The purpose of this study was to investigate the effects of varying the initiation of free mobilization on elbow ROM and histological features in an animal model of elbow posttraumatic joint contracture.MethodsTraumatic elbow dislocation was surgically induced unilaterally in rats. Injured forelimbs were immobilized in bandages for 3, 7, 14, or 21 days; free mobilization was then allowed until 42 days after injury. Post-mortem joint ROM testing and histological analysis were performed. One-way analysis of variance was used to compare ROM data between control and injured groups, and Pearson correlations were performed between ROM parameters and histological outcomes.ResultsLonger immobilization periods resulted in greater ROM reductions. The anterior and posterior capsule showed increases in cellularity, fibroblasts, adhesions, fibrosis, and thickness, whereas the measured outcomes in cartilage were mostly unaffected. All measured histological characteristics of the capsule were negatively correlated with ROM, indicating that higher degrees of pathology corresponded with less ROM.ConclusionsLonger immobilization periods resulted in greater ROM reductions, which correlated with worse histological outcomes in the capsule in an animal model of posttraumatic elbow contracture. The subtle differences in the timing of ROM and capsule tissue changes revealed in the present study provide new insight into the distinct timelines of biomechanical changes as well as regional tissue pathology.Clinical relevanceThis study showed that beginning active mobilization 3 days after injury minimized posttraumatic joint contracture, thereby supporting an immediate-motion clinical treatment strategy (when possible). Furthermore, uninjured but pathologically altered periarticular tissues near the injury location may contribute to more severe contracture during longer immobilization periods as the disease state progresses.

Project description:Optimal acute management of the highly comminuted distal ulna head/neck fracture sustained in conjunction with an unstable distal radius fracture requiring operative fixation is not well established. The purpose of the present study was to determine the clinical, radiographic, and functional outcomes following acute primary distal ulna resection for comminuted distal ulna fractures performed in conjunction with the operative fixation of unstable distal radius fractures. Between 2000 and 2007, 11 consecutive patients, mean age 62 years (range, 30-75) were treated for concomitant closed, comminuted, unstable fractures of the distal radius and ulna metaphysis. All 11 patients underwent distal ulna resection through a separate dorsal ulnar incision with ECU tenodesis following surgical fixation of the distal radius fracture. According to the Q modifier of the Comprehensive Classification of Fractures, there were six comminuted fractures of the ulnar neck (Q3) and five fractures of the head/neck (Q5). Operative fixation of the distal radius fracture included volar plate fixation in four patients and spanning external fixation with supplemental percutaneous Kirschner wires in seven patients. At a mean of 42 months (range, 18-61 months) postoperatively, clinical, radiographic, and wrist-specific functional outcome with the modified Gartland and Werley wrist score were evaluated. At latest follow-up, mean wrist range of motion measured 53 degrees flexion (range, 35-60 degrees), 52 degrees extension (range, 30-60 degrees), 81 degrees pronation (range, 75-85 degrees), and 77 degrees supination (range, 70-85 degrees). Mean grip strength measured 90% of the contralateral, uninjured extremity (range, 50-133%). No patient had distal ulna instability. Final radiographic assessment demonstrated restoration of distal radius articular alignment. According to the system of Gartland and Werley as modified by Sarmiento, there were seven excellent and four good results. No patient has required a secondary surgical procedure. Acute primary distal ulna resection yields satisfactory clinical, radiographic, and functional results in appropriately selected patients and represents a reliable alternative to open reduction and internal fixation when anatomic restoration of the distal ulna/sigmoid notch cannot be achieved. Primary distal ulna resection with distal radius fracture fixation may help avoid secondary procedures related to distal ulna fixation or symptomatic post-traumatic distal radioulnar joint arthrosis.

Project description:BACKGROUND:Posttraumatic elbow contractures in children and adolescents are challenging to manage, and studies investigating surgical treatment are limited by the rarity of this condition. Small case series have shown variable gains in immediate and long-term elbow arc of motion after open surgical release. We reviewed our experience with open surgical release of posttraumatic elbow contracture in patients <21 years old at 2 institutions. METHODS:A retrospective chart review identified patients who underwent posttraumatic open elbow contracture release by 2 surgeons at 2 institutions between 2006 and 2013. Nontraumatic contractures and arthroscopic releases were excluded. Twenty-six patients were included in this study. Mean age at the time of injury was 12 years (5 to 19 y) and at the time of surgery was 14 years (7 to 20 y). Capsulotomy, osteoplasty, removal of hardware, ulnar nerve release or transposition, and ligament reconstruction were performed through medial and lateral approaches as indicated by the pathology. Ten patients had ligament repair or stabilization, and 16 patients used a continuous passive motion (CPM) postoperatively. Outcomes included active range of motion and complications. RESULTS:Mean time from injury to surgical release was 29 months. Mean postoperative follow-up was 42 months. Elbow active flexion-extension and forearm rotation arcs both increased significantly by a mean of 49 and 70 degrees, respectively, at final follow-up. A mean 85% of intraoperative flexion-extension arc was maintained at final follow-up. Ligament repair or reconstruction and the use of a postoperative CPM did not significantly change these outcomes. Outcomes were not significantly different if our contracture release was performed within a year from injury. Patients who had surgery before our contracture release had decreased restoration of forearm rotation after release. Complications included 2 recurrent contractures (1 used a CPM and 1 did not), and 2 postoperative ulnar neuropathies (1 used a CPM and 1 did not). CONCLUSIONS:Open contracture release for posttraumatic elbow contracture in an adolescent population can significantly improve active range of motion. LEVEL OF EVIDENCE:Level 3-therapeutic.

Project description:BACKGROUND:Reoperation rates are high after surgery for hip fractures. We investigated the effect of a sliding hip screw versus cancellous screws on the risk of reoperation and other key outcomes. METHODS:For this international, multicentre, allocation concealed randomised controlled trial, we enrolled patients aged 50 years or older with a low-energy hip fracture requiring fracture fixation from 81 clinical centres in eight countries. Patients were assigned by minimisation with a centralised computer system to receive a single large-diameter screw with a side-plate (sliding hip screw) or the present standard of care, multiple small-diameter cancellous screws. Surgeons and patients were not blinded but the data analyst, while doing the analyses, remained blinded to treatment groups. The primary outcome was hip reoperation within 24 months after initial surgery to promote fracture healing, relieve pain, treat infection, or improve function. Analyses followed the intention-to-treat principle. This study was registered with ClinicalTrials.gov, number NCT00761813. FINDINGS:Between March 3, 2008, and March 31, 2014, we randomly assigned 1108 patients to receive a sliding hip screw (n=557) or cancellous screws (n=551). Reoperations within 24 months did not differ by type of surgical fixation in those included in the primary analysis: 107 (20%) of 542 patients in the sliding hip screw group versus 117 (22%) of 537 patients in the cancellous screws group (hazard ratio [HR] 0·83, 95% CI 0·63-1·09; p=0·18). Avascular necrosis was more common in the sliding hip screw group than in the cancellous screws group (50 patients [9%] vs 28 patients [5%]; HR 1·91, 1·06-3·44; p=0·0319). However, no significant difference was found between the number of medically related adverse events between groups (p=0·82; appendix); these events included pulmonary embolism (two patients [<1%] vs four [1%] patients; p=0·41) and sepsis (seven [1%] vs six [1%]; p=0·79). INTERPRETATION:In terms of reoperation rates the sliding hip screw shows no advantage, but some groups of patients (smokers and those with displaced or base of neck fractures) might do better with a sliding hip screw than with cancellous screws.

Project description:BACKGROUND:Proximal humerus fractures are the third most common fracture in the elderly population and are expected to increase due to the aging population. Surgical fixation with locking plate technology has increased over the last decade despite a lack of proven superiority in the literature. Three previous randomized controlled trials have not shown a difference in patient-centered outcomes when comparing non-operative treatment with open reduction and internal fixation. Low patient enrollment and other methodological concerns however limit the generalizability of these conclusions and as a result, management of these fractures remains a controversy. By comparing the functional outcomes of locked plate surgical fixation versus non-operative treatment of displaced three and four-part proximal humerus fractures in the elderly population with a large scale, prospective, multi-centered randomized controlled trial, the optimal management strategy for this common injury may be determined. METHODS:We will conduct a prospective, single blind randomized controlled parallel arm trial to compare non-operative management of proximal humerus fractures with open reduction and internal fixation using locked plating technology. One-hundred and sixty patients > age 60 with acute 3- or 4- part proximal humerus fractures will be randomized to either open reduction and internal fixation with locked plating technology or non-operative management treatment arms. The primary outcome measure is the Constant Score at 24 months post-operative. Secondary outcome measures include the American Shoulder and Elbow Surgeon's Score (ASES), EuroQol EQ-5D-5 L Health Questionnaire Score, short form PROMIS upper extremity score and IPAQ for the elderly score. Further outcome measures include assessment of the initial classification, displacement and angulation and the quality of surgical reduction via a standard computed tomography (CT) scan; rates of non-union, malunion, arthrosis, osteopenia or other complications including infection, nerve injury, intra-articular screw penetration, reoperation rates and hospital re-admission rates. DISCUSSION:The results of this trial will provide Level 1 evidence to guide decision-making in the treatment of proximal humerus fractures in the elderly population.
