Posttraumatic Compressive Neuropathy of the Deep Motor Branch of the Ulnar Nerve Caused by Heterotopic Ossification.

We report a case of posttraumatic compressive neuropathy of the deep motor branch of the ulnar nerve occurring in the setting of heterotopic ossification following a direct blow to the hypothenar eminence. Over several weeks, the patient developed ring and little finger claw deformities and atrophy of his first dorsal interosseous and adductor pollicis muscles with sparing of sensation. Electromyography and nerve conduction study localized the area of injury, and computed tomography confirmed the presence of heterotopic bone near the deep motor branch of the ulnar nerve. Intraoperatively, the deep motor branch of the ulnar nerve was under tension as it traversed volarly over the hook of hamate and heterotopic bone. Decompression of the deep motor branch of the ulnar nerve with resection of heterotopic bone and the hook of hamate was performed. Six months postoperatively, the patient demonstrated resolution of clawing and improving strength of his ulnar nerve innervated intrinsic muscles.

Preoperative Expectations in Hand Surgery Patients.

Introduction Studies have shown a link between patients' preoperative expectations and their postoperative satisfaction. However, limited studies exist concerning patient factors associated with higher preoperative expectations in the hand surgery population. This study analyzed preoperative expectation scores of patients undergoing hand surgery and aimed to determine associated patient characteristics. Materials and Methods A total of 418 elective hand surgery patients aged 15 years and older enrolled in a prospectively collected orthopaedic registry from June 2015 to December 2018 were analyzed. Patients were administered preoperative questionnaires including six Patient-Reported Outcome Measurement Information System domains and other activity and pain scales. Expectation scores were measured using the six domains of the Musculoskeletal Outcomes Data Evaluation and Management System expectations questionnaire. Bivariate and multivariable analyses were conducted to identify independent predictors of higher expectations. Results Overall, patients had high expectations (≥ 80.0) of their hand surgery. Higher mean expectation scores were seen with females, college graduates, better baseline health status, and fewer prior hand surgeries ( p < 0.05 for all). No significant associations were found among the Common Procedural Terminology codes and expectations. Multivariable analysis confirmed that college degree ( p = 0.023) and less pain ( p = 0.008) were predictive of higher baseline expectations. Conclusion In sum, more educated patients with less pain at baseline and better baseline health status have higher expectations of their hand surgery. Hand surgeons can use these results to help focus their preoperative counseling and expectation management.

Higher preoperative expectations predict better outcomes in shoulder surgery patients.

PURPOSE: The purpose of this study is to determine if preoperative expectations (PE) are an independent predictor of greater 2-year outcomes and greater improvement from baseline in shoulder surgery patients. METHODS: Two-hundred and sixteen patients who underwent shoulder surgery at one institution were studied. Patients completed both preoperative and 2-year follow-up questionnaires including PROMIS (Patient-Reported Outcome Measurement Information System) computer-adaptive testing in six domains, American Shoulder and Elbow Surgeons (ASES) score, shoulder numeric pain scale (NPS), and the Marx Shoulder Activity Rating Scale (MARS). PE were measured using the Musculoskeletal Outcomes and Data Evaluation Management System (MODEMS) expectations domain, and satisfaction was measured via the Surgical Satisfaction Questionnaire (SSQ-8). RESULTS: The mean PE score was 86.2 ± 17.8. Greater PE were associated with significantly better 2-year scores for ASES, NPS, MARS, SSQ8, and PROMIS domains of Physical Function, Fatigue, Pain Interference Fatigue and Social Satisfaction. Multivariable analyses demonstrated that greater PE were an independent predictor of both better 2-year scores and greater improvement for PROMIS SS (p < 0.001), ASES (p = 0.007), and shoulder NPS (p = 0.011). CONCLUSION: Greater PE are positively associated with numerous patient-based outcomes 2 years after surgery. With regards to pain relief, shoulder function, and social satisfaction, higher PE are also predictive of better outcome scores and more improvement. This study suggests that preoperative assessment of shoulder surgery PE is important, and that counseling patients to optimize realistic expectations may lead to superior outcomes.

Preoperative Expectations of Patients Undergoing Knee Surgery.

There is limited validated data regarding the relationship between preoperative expectations and patient-reported outcomes (PROs) in patients undergoing knee surgery. The purpose of this study was to (1) assess the preoperative expectations of patients undergoing knee surgery and (2) determine the relationship between preoperative patient demographics, PROs, and preoperative patient expectations. We hypothesized that younger patients with worse function and worse general health status would have greater expectations of knee surgery. We analyzed data from 399 patients undergoing knee surgery at an urban academic medical center. We utilized the Musculoskeletal Outcomes Data Evaluation and Management System to measure preoperative expectations. Multiple legacy PRO measures were recorded, as well as the new Patient-Reported Outcomes Measurement Information Systems (PROMIS) Computer Adaptive Testing. Nonparametric statistical analyses were performed to determine significance. Overall, patients undergoing knee surgery had high expectations, with a mean of 88.0 (95% confidence interval [CI], 86.7-89.3) and median of 91.7 (95% CI, 89.2-94.3). Greater preoperative expectations of knee surgery were associated with higher income, surgically naïve knee, lower Charlson Comorbidity Index, better PROMIS Depression and Anxiety scores, greater Marx knee activity scores, and lower total body pain (p < 0.05). Preoperative expectations of patients undergoing knee surgery are associated with a history of prior knee surgery, income, general and mental health, activity, and pain. Expectations were also found to be associated with PRO measures of function and psychological well-being. These findings may have implications for patient education and shared decision-making preoperatively. The level of evidence for the study is IV.

Preoperative expectations and early postoperative met expectations of extremity orthopaedic surgery.

BACKGROUND: Preoperative patient expectations and met expectations are likely associated with the outcome of treatment. However, there is a lack of data regarding the preoperative expectations and early postoperative met expectations of patients undergoing extremity orthopaedic surgery. The purpose of this study was to identify the predictors of early postoperative met expectations in a cohort of patients undergoing extremity orthopaedic surgery and to assess the relationship between patient expectations and patient-reported outcome (PRO) measures. We hypothesized that patients with higher preoperative expectation scores and higher postoperative met expectation scores would have better early postoperative outcomes. METHODS: Four hundred thirty-five patients age seventeen and older who underwent extremity orthopaedic surgery at one institution were prospectively enrolled in this study. Each patient completed a preoperative questionnaire that included an assessment of demographics, pain, function, general health, treatment expectations, activity level, and Patient-Reported Outcome Measurement Information System (PROMIS) computer adaptive testing. Expectations were evaluated using the Expectations Domain of the Musculoskeletal Outcomes Data Evaluation and Management System (MODEMS) questionnaire. Patients completed a follow-up questionnaire two weeks after surgery that also assessed MODEMS met expectations and satisfaction (Surgical Satisfaction Questionnaire (SSQ-8)). RESULTS: The mean preoperative expectation score was 86.95 ± 16.59, and the mean postoperative met expectation score was 55.02 ± 27.63 (0-100 scale with 100 representing the highest level of expectations). Greater met expectations were significantly associated with white race (p = 0.025), college degree (p = 0.011), and higher income (p = 0.002). Greater met expectations were also significantly associated with greater postoperative physical function, social satisfaction, activity level, and subjective improvement, as well as lower pain interference, joint pain, body pain, fatigue, anxiety, and depression (p < 0.01 for each). Multivariable analysis results found that less postoperative joint pain and greater postoperative social satisfaction, improvement, and physical function were all significant independent predictors of greater met expectations at two weeks postoperative (p < 0.01 for each). CONCLUSION: Greater preoperative expectations are associated with better activity and less pain two weeks after surgery. Met expectations of extremity orthopaedic surgery were associated with postoperative physical function, social satisfaction, activity, pain, anxiety, depression, and subjective improvement. These results may have implications for preoperative counseling and risk factor modification.

Provisional Minifragment Plate Fixation of Acetabular Fractures-A Technical Trick.

SUMMARY: Acetabular fractures may not always be amenable to classic clamp-assisted reductions and interfragmentary lag screw fixation. The routine clamp-assisted reductions with limited osseous territory availability can inhibit typical 3.5-mm reconstruction plate application. Provisional minifragment plate fixation of these fracture patterns with subsequent clamp removal allows for definitive plate application. The provisional minifragment plates may also be retained to theoretically augment fixation. The authors present a step-by-step technique and clinical series of 57 patients demonstrating provisional minifragment fixation of elementary (n = 8) and associated (n = 49) acetabular fractures.

Patients undergoing shoulder surgery have high preoperative expectations.

PURPOSE: The primary aims of this study were to (1) assess the preoperative expectations of patients undergoing shoulder surgery, and (2) determine the relationship between preoperative patient demographics, PROs, and preoperative patient expectations. It was hypothesized that younger patients with worse function and worse health status had higher expectations of shoulder surgery. METHODS: Data from a total of 319 patients (319 shoulders) from 2015-2018 were analyzed. Patients completed a series of questionnaires covering demographics and patient-reported outcome measures. Expectations of treatment were evaluated using the Musculoskeletal Outcomes Data Evaluation and Management System. Bivariate analyses were performed to determine the significance of identified associations. RESULTS: The study population consisted of 186 males and 133 females. The mean age was 46.9 (± 17.2), and the mean BMI was 30.1 (± 6.8). Overall, patients had high expectations of shoulder surgery, with a mean score of 84.7 (± 19.3). The most commonly performed procedure in the study population was arthroscopic rotator cuff repair. There was a significant association between pre-treatment expectations and ethnicity, previous shoulder surgery, employment status, income level, tobacco use, preoperative opioid use, depression, and ASA score. CONCLUSION: The findings suggest that patients undergoing shoulder surgery have high overall preoperative expectations, which were significantly associated with ethnicity, surgical history, opioid use, and employment status, and with multiple patient-reported outcome measures including physical function, pain interference, fatigue, and depression. Nevertheless, by discussing expectations preoperatively, orthopaedic surgeons can help patients develop high but realistic expectations to improve outcomes and satisfaction. LEVEL OF EVIDENCE: IV.
