Prosthetic resurfacing of engaging posterior capitellar defects in recurrent posterolateral rotatory instability of the elbow

BACKGROUND

Posterolateral rotatory instability (PLRI) is a common mechanism of recurrent elbow instability. While the essential lesion is a deficiency in the lateral ulnar collateral ligament (LUCL), there are often associated concomitant bony lesions, such as an Osborne-Cotterill lesions (posterior capitellar fractures) and marginal radial head fractures, that compromise stability. Currently, there is no standard treatment for posterior capitellar deficiency associated with recurrent PLRI.

METHODS

We conducted a retrospective review of five patients with recurrent PLRI of the elbow associated with a posterior capitellar impaction fracture engaging with the radial head during normal range of motion. The patients were treated surgically with LUCL reconstruction or repair and off-label reconstruction of the capitellar joint surface using a small metal prosthesis designed for metatarsal head resurfacing (HemiCAP toe classic).

RESULTS

Five patients (three adolescent males, two adult females) were treated between 2007 and 2018. At a median follow-up of 5 years, all patients had complete relief of their symptomatic instability. No patients had pain at rest, but two patients had mild pain (visual analog scale 1-3) during physical activity. Three patients rated their elbow as normal, one as almost normal, and one as greatly improved. On short-term radiographic follow-up there were no signs of implant loosening. None of the patients needed reoperation.

CONCLUSIONS

Recurrent PLRI of the elbow associated with an engaging posterior capitellar lesion can be treated successfully by LUCL reconstruction and repair and filling of the capitellar defect with a metal prosthesis. This treatment option has excellent clinical results in the short-medium term. Level of evidence: IV.

Long-Term Patient-Reported Outcomes After Arthroscopic Debridement of Grade 3 or 4 Capitellar Osteochondritis Dissecans Lesions

BACKGROUND

Arthroscopic debridement for osteochondritis dissecans (OCD) lesions of the capitellum is a relatively common and straightforward surgical option for failure of nonoperative management. However, the long-term outcomes of this procedure remain unknown.

HYPOTHESIS

Arthroscopic debridement of capitellar OCD would provide satisfactory long-term improvement in patient-reported outcomes.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

Patients aged ≤18 years who underwent arthroscopic debridement procedures for OCD lesions (International Cartilage Repair Society grades 3 and 4) were identified. Procedures included loose body removal when needed and direct debridement of the lesion; marrow stimulation with drilling or microfracture was added at the discretion of each surgeon. The cohort consisted of 53 elbows. Patient evaluation included visual analog scale for pain; motion; subjective satisfaction; Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores; reoperation; and rate of return to sports.

RESULTS

At a mean 11 years of follow-up (range, 5-23 years), the median visual analog scale score for pain was 0, and 96% of patients reported being improved as compared with how they were before surgery. The mean ± SD QuickDASH score was 4 ± 9 points (range, 0-52 points), and 80% of patients returned to their sports of interest. The arc of motion significantly improved from 115°± 28° preoperatively to 130°± 17° at latest follow-up (P = .026). Seven elbows (13%) required revision surgery for OCD lesions, resulting in high rates of overall survivorship free of revision surgery: 90% (95% CI, 80%-96%) at 5 years and 88% (95% CI, 76%-94%) at 10 years. At final follow-up, 7 all-cause reoperations were performed without revision surgery on the OCD lesion.

CONCLUSION

Arthroscopic debridement of grade 3 or 4 OCD lesions of the capitellum produced satisfactory patient-reported outcomes in a majority of elbows, although a subset of patients experienced residual symptoms. The inherent selection bias of our cohort should be considered when applying these results to the overall population with OCD lesions, as we do not recommend this procedure for all patients.

Radial Head Prosthetic Replacement in Adolescents: A Report of 5 Cases

BACKGROUND

The management of severe radiocapitellar joint pathologies in young patients is challenging. Radial head arthroplasty (RHA) is a treatment option in the adult population, but most surgeons avoid implementing it in younger patients, and there are no published results for patients younger than 16 years.

METHODS

Our retrospective cohort describes 5 patients (4 male 1 female) who underwent cementless modular RHA at an average age of 14 years (range: 13 to 15). The preoperative diagnoses were post-traumatic radiocapitellar incongruity and arthrosis because of previous Salter-Harris type 3 or 4 fractures of the radial head in 3 cases; and axial instability of the forearm following failed radial head excision in 2 cases. Because of the complexity of the elbow pathology in these cases, all underwent concomitant procedures including: contracture release (5 cases), corrective ulnar osteotomy (2 cases), distal ulnar shortening osteotomy, excision of radioulnar synostosis, microfracture of the capitellum, and partial excision of the medial triceps (1 case each). Collected data included patient-reported outcomes, visual analog scale pain score at rest and during physical activity and radiographic assessment of arthritis and prosthesis loosening.

RESULTS

Average clinical follow-up was 8 years (range: 3 to 13). All 5 patients were pain-free at rest, and 3 reported moderate elbow pain (visual analog scale: 5 to 6) with physical activity. At an average radiographic follow-up of 3 years (range: 0.5 to 5), 3 patients showed mild progression of elbow arthrosis, but there were no signs of progressive capitellar erosion or implant loosening. Only 1 complication was noted-development of heterotopic ossification in 1 patient, which required open heterotopic ossification excision and contracture release 2 years following the RHA. None of the patients required prosthesis revision or removal.

CONCLUSION

RHA was successful in improving pain and axial forearm stability in this very small series of adolescent patients. Concerns regarding long-term longevity and complications still exist. Considering the lack of other reliable treatment options, RHA may be indicated in this challenging patient population.

Instruments to Measure Perceptions in the Emergency Department Provider-Patient with Sickle Cell Disease Interaction: Findings of an Integrative Review from a Ph.D. Project

Background & Purpose:

The purpose of this review is to examine instruments that measure providers' perceptions of adult patients with Sickle Cell Disease (SCD), examine instruments that measure adult patients with SCD perceptions of providers' behaviors, and determine optimal instruments to use in evaluating the perceptions of Emergency Department (ED) providers and adult patients with SCD of one another's behaviors after an interaction in the ED.

Methods:

An integrative review was conducted searching EBSCOhost and PubMed databases using the keywords: measure [OR] measure* [OR] assess* [OR] scale [OR] survey [OR] tool [AND] stigma* [OR] stereotype [OR] prejudice [OR] bias [OR] perception [OR] attitude [OR] discrimination [OR] racism [OR] behavior [AND] interaction [OR] relationship [OR] communication [AND] sickle cell. Initial search located 256 articles, but only 15 articles were included in the final review.

Results:

Fifteen articles reporting six instruments were reviewed. Four instruments evaluated a provider’s perceptions of patients with SCD behaviors, and two instruments evaluated how patients with SCD perceived provider behaviors. The two patient-focused instruments and three provider-focused instruments were found to be adequately reliable and valid according to the Psychometric Grading Framework (PGF).

Conclusions:

The findings suggest that the General Perceptions About Sickle Cell Disease Patients Scale would be an optimal instrument to evaluate ED providers' perceptions of adult patients with SCD behaviors. One patient-focused instrument, The Sickle Cell Health-Related Stigma Scale (SCD-HRSS), reported adequate reliability and validity but was not specific to measuring the patient's perceptions of ED providers' behaviors, nor was it administered in the ED environment. The SCD-HRSS Doctors subscale has potential adaptability for use in measuring patients with SCD perceptions of ED provider behaviors in the ED environment.
