Resection Outcomes of Posttraumatic Elbow Heterotopic Ossification: Multicenter Case Series at a Minimum 5-Year Follow-Up

BACKGROUND

Heterotopic ossification (HO), a common complication after elbow trauma, causes severe limb disability. Resection is usually performed for posttraumatic elbow HO (PTEHO) to regain mobility, and although heavily reported, there has been no long-term (minimum, 5-year) follow-up.

METHODS

A total of 173 patients who underwent PTEHO resection were followed up for a minimum of 5 years in 4 hospitals between January of 2015 and August of 2016. Demographics, disease characteristics, and preoperative and minimum 5-year assessments were collected. After controlling for potential variables when dividing long-term range of motion (ROM) into less than 120 degrees and greater than or equal to 120 degrees, risk factors for ROM recovery to modern functional arc were identified through multivariable regression analysis.

RESULTS

Clinically important improvements in ROM from 39 degrees to 124 degrees were obtained at final follow-up, and 74.6% achieved modern functional arc (≥120 degrees). Mayo Elbow Performance Index had clinically important increases from 69 to 93 points at final follow-up, and 96.5% reported excellent to good. Pain (numeric rating scale, from 1.9 to 0.6 points) and ulnar nerve symptoms were improved. The total complication rate was 15.6%, including new-onset ulnar nerve symptoms (5.8%), HO recurrence with clinical symptoms (6.9%), elbow instability (1.7%), and joint infection (1.2%). Previously reported high body mass index ( P = 0.002) and long disease duration ( P = 0.033) were equally identified as risk factors for not achieving modern functional arc; meanwhile, tobacco use ( P = 0.024) and ankylosed HO ( P < 0.001) were found to be new risk factors.

CONCLUSIONS

Resection yields satisfactory outcomes for PTEHO at long-term follow-up of a minimum of 5 years. High body mass index, tobacco use, long disease duration, and ankylosed HO would negatively affect ROM recovery to a modern functional arc (≥120 degrees).

Surgical management for primary osteoarthritis of the elbow

The objective of this review is to summarize the surgical options for primary osteoarthritis of the elbow, reported clinical outcomes, and suggested indications in previous literatures. The surgical management of primary elbow arthritis has evolved because of an improved understanding of pathologic mechanisms and manifestations as well as the development of novel surgical techniques and devices. Osteocapsular arthroplasty (OCA), elbow debridement, distraction arthroplasty, and total elbow arthroplasty (TEA) have been employed for managing elbow osteoarthritis. Elbow debridement and OCA can be helpful in most cases of symptomatic elbow arthritis. TEA is usually recommended for end-stage arthritis in elderly patients after prosthetic implants have been in place for long periods or after complications. Distraction arthroplasty might find a place in the treatment of younger, active patients with end-stage arthritis.

Primary Elbow Osteoarthritis: Evaluation and Management

Most patients with primary osteoarthritis of the elbow report a history of heavy lifting with the affected upper extremity . Conservative treatment, including activity modifications, nonsteroidal anti-inflammatory drugs and the occasional intraarticular corticosteroid injection, may provide adequate pain relief in earlier stages . When surgery is required, and despite the presence of cartilage wear, many patients with primary elbow osteoarthritis experience substantial pain improvement with joint preserving procedures . The ulnar nerve needs to be carefully assessed and addressed at the time of surgery . Although open debridement procedures are effective, arthroscopic osteocapsular arthroplasty has emerged as the surgical procedure of choice . Total elbow arthroplasty is very successful in terms of pain relief and function, but it is reserved for patients with end-stage osteoarthritis who are relatively older and have failed joint preserving procedures.

Risk Factors for Elbow Joint Contracture After Surgical Repair of Traumatic Elbow Fracture

PURPOSE

The ability to predict contracture development after elbow fracture would benefit patients and physicians. This study aimed to identify factors associated with the development of posttraumatic elbow joint contracture.

METHODS

A retrospective review of elbow fractures (AO/Orthopaedic Trauma Association [OTA] type 13 and 21) treated at one institution between 2011 and 2015 was performed. Data collected included demographics, injury information, treatment, and postoperative elbow range of motion (ROM). Multivariate logistic regression analyses were performed to identify factors associated with contracture development. Notable contracture was defined as an arc of motion less than 100° flexion/extension, which has been associated with reduced ability to perform activities of daily living.

RESULTS

A total of 278 patients at least 1 8 years of age underwent surgical repair of an elbow fracture or fracture-dislocation during the study period and had at least 6 months of postoperative follow-up. Forty-two (15.1%) developed a clinically notable elbow contracture, of whom 29 (69.0%) developed heterotopic ossification (HO). Multivariate analysis of preoperative variables demonstrated that AO/OTA 13-C fracture classification (odds ratio [OR], 13.7, P = 0.025), multiple noncontiguous fractures (OR, 3.7, P = 0.010), and ulnohumeral dislocation at the time of injury (OR, 4.9, P = 0.005) were independently associated with contracture development. At 6 weeks postoperatively, an arc of elbow ROM less than 50° flexion/extension (OR, 23.0, P < 0.0005) and the presence of HO on radiographs (OR, 6.7, P < 0.0005) were found to be independent risk factors for significant elbow stiffness.

DISCUSSION

Ulnohumeral dislocation, multiple noncontiguous fractures, AO/OTA 13-C fracture classification, limited elbow ROM at 6 weeks postoperatively, and the presence of radiographic HO at 6 weeks postoperatively are associated with contracture development after surgical elbow fracture repair. Patients with these risk factors should receive aggressive physical therapy and be counseled as to the possible development of a contracture requiring surgical intervention.

Open elbow arthrolysis for post-traumatic elbow stiffness: an update

Post-traumatic elbow stiffness is a disabling condition that remains challenging for upper limb surgeons. Open elbow arthrolysis is commonly used for the treatment of stiff elbow when conservative therapy has failed. Multiple questions commonly arise from surgeons who deal with this disease. These include whether the patient has post-traumatic stiff elbow, how to evaluate the problem, when surgery is appropriate, how to perform an excellent arthrolysis, what the optimal postoperative rehabilitation is, and how to prevent or reduce the incidence of complications. Following these questions, this review provides an update and overview of post-traumatic elbow stiffness with respect to the diagnosis, preoperative evaluation, arthrolysis strategies, postoperative rehabilitation, and prevention of complications, aiming to provide a complete diagnosis and treatment path.

Development and validation of a new elbow-specific scoring system for patients with elbow stiffness: the Shanghai Elbow Dysfunction Score

BACKGROUND

Clinical scoring systems are increasingly important and popular for the evaluation of orthopedic patients. Elbow stiffness commonly causes functional impairment and upper-limb disability. The purpose of this study was to develop and validate a new elbow-specific assessment score to evaluate joint function in patients with elbow stiffness.

METHODS

The new system, the Shanghai Elbow Dysfunction Score (SHEDS), was developed in 3 portions: elbow motion capacities, elbow-related symptoms, and patient satisfaction level. A total of 73 patients with elbow stiffness were prospectively included. Intraclass correlation coefficients and Cronbach α values were calculated for test-retest reliability and internal consistency, respectively. Construct validity was assessed by correlating the SHEDS with previously validated scoring systems. Effect sizes (ES) and standardized response means (SRMs) were calculated for responsiveness.

RESULTS

Positive reliability with an intraclass correlation coefficient of 0.83 and adequate homogeneity with a Cronbach α value of 0.74 were found for the SHEDS. Good to excellent validity using Spearman correlation coefficients (SCCs) were determined for the total (0.51-0.82), motion (0.65-0.89), and symptom (0.35-0.53) scores. Responsiveness was large for the total ES, 3.48; SRM, 2.96), motion (ES, 2.54; SRM, 2.08), and symptom (ES, 1.26; SRM, 1.14) scores. There were no ceiling or floor effects. Significant positive correlations were found between patient satisfaction levels and the final scores (SCC, 0.62), as well as the score changes of the SHEDS (SCC, 0.42).

CONCLUSION

Our results suggest that the newly developed SHEDS is an excellent, comprehensive, valid scoring system to evaluate joint function in patients with elbow stiffness.
