Surgical Outcomes in Charcot Arthropathy.

Treatment of Charcot neuroarthropathy (CN) of the foot and ankle remains challenging for both patients and surgeons. Nonoperative treatment with cast/orthosis immobilization has long been the mainstay of treatment, but surgical intervention has gained interest to improve poor long-term outcomes. A review of existing data on the operative management of CN demonstrates the potential benefits but also the continued risks associated with treatment. Additionally, a retrospective review of cohorts managed with limited surgical interventions (wound debridements, exostectomies, and other surgical procedures) compared to reconstructive procedures provides additional insight into the surgical management of CN.

Histopathology of long head of biceps tendon removed during tenodesis demonstrates degenerative histopathology and not inflammatory changes.

BACKGROUND: The aim of this study is to describe and quantitatively analyze the histopathology of proximal long head biceps (LHB) tendinopathy in patients who have undergone LHB tenodesis. The hypothesis is that severe histopathologic changes of the LHB tendon (LHBT) will most likely be reflected with improved postoperative clinical outcomes. METHODS: The study included patients with isolated LHB tendinopathy or LHB tendinopathy associated with concomitant shoulder pathologies. All had failed conservative treatment (12 months) and had a positive pain response (> 50% reduction) pre-operatively after LHB tendon injection with local anesthetic. All underwent biceps tenodesis procedure between 2008 and 2014. Tendon specimens were collected and histologically analyzed with the semi-quantitative Bonar scoring system. Minimum follow-up time was 1 year. A subset of patients was retrospectively reviewed postoperatively and evaluated employing visual analogue score (VAS), short form survey (SF-12), American Shoulder and Elbow Surgeon (ASES) score, Disability of Arm, Shoulder and Hand (DASH) score, and Oxford Shoulder Score (OSS) and postoperative return to work status. RESULTS: Forty-five biceps tendon specimens were obtained from 44 patients (mean age 50 ± 9.6 years). Histopathological analyses demonstrated advanced degenerative changes with myxoid degeneration and marked collagen disorganization. Minimal inflammation was identified. There were no regional differences in histopathological changes. Clinical outcomes did not correlate significantly with severity of histopathologic changes. CONCLUSIONS: This study confirms that LHBT specimens in patients undergoing tenodesis demonstrate with the use of the Bonar score histopathologic changes of chronic degeneration and not inflammation. The correct histopathologic terminology for this process is LHB tendinosis. The histopathological changes appear uniform throughout the entire length of the LHBT which may inform the nature of the procedure performed.

Analysis of Wheeled Knee Walker Use following Foot and Ankle Surgery or Injury.

To determine patient satisfaction and safety with wheeled knee walkers, we performed a retrospective, observational, and descriptive study. Inclusion criteria were age ≥18 years, unilateral foot or ankle surgery, non-weightbearing status, and being given the option of using the knee walker. Surveys were sent to eligible patients, and chart review included only those patients who returned surveys. Primary endpoints were occurrence and frequency of falls. Secondary endpoints were patient demographics, comorbidities, knee walker characteristics, duration of use, and patient satisfaction. We also attempted to identify associations between falls and patient characteristics. Eighty participants, 51 females and 29 males, responded adequately to the survey. The mean age of respondents was 55.6 ± 13.0 years and their mean body mass index (BMI) was 30.2 ± 5.9 kg/m2. Most used a steerable, 4-wheeled knee walker. Almost half (46%) had no prior experience with any type of walking aids, and none had experience using a knee walker. Two thirds (66%) did not receive any instruction on usage of the knee walker. Thirty-four (43%) of the 80 respondents fell while using the knee walker; nearly two thirds (62%) of those who fell reported multiple falls. Sixteen (55%) of 29 males compared to 18 (36%) of 50 females reported falling (p = .097). There was no statistical association between falls and age, BMI, or number of comorbidities. Most respondents (91%) who fell still reported satisfaction with the knee walker. Nearly half (43%) experienced falling, and nearly two thirds (64%) of those who fell had multiple falls.

Osseous Healing in Foot and Ankle Surgery with Autograft, Allograft, and Other Orthobiologics.

In the surgical treatment of foot and ankle abnormality, many problems require bone grafting for successful osseous union. Nonunion, reconstruction, and arthrodesis procedures pose specific challenges due to bony defects secondary to trauma, malunions, or previous surgery. Nonunion in foot and ankle arthrodesis is a significant risk and is well documented in recent literature. This article is a review of the recent literature regarding the use of bone graft and orthobiologics in foot and ankle surgery.

Role of Depression in Outcomes of Low-Energy Distal Radius Fractures in Patients Older Than 55 Years.

OBJECTIVES: This study examines depression and outcomes in patients older than 55 years with distal radius fracture. DESIGN: Prospective data collection included patient characteristics, treatment, general and limb symptoms and disability, and complications at baseline, 3 months, and 1 year. Bivariate analysis and multivariable linear regression were used to assess relationships between depression and outcome measures, specifically the Short Form-36 (SF-36), Disability of the Arm, Shoulder, and Hand (DASH) scores, and the Centre of Epidemiologic Studies Depression (CES-D) scale. SETTING: The study was conducted in a level-1 trauma center. PARTICIPANTS: All patients older than 55 years with isolated distal radius fracture were recruited (2007-2011). INTERVENTION: Patients were treated operatively or nonoperatively. MAIN OUTCOME MEASURES: The SF-36 and DASH scores measured general and upper extremity status. Depression was measured using CES-D scale. All complications were recorded. RESULTS: Of 228 patients, 25% were depressed at baseline, 32% at 3 months, and 26% after 1 year. Thirty-two patients (14%) had complications. There was no relationship between depression at baseline and complications; however, there was a statistically significant relationship at 3 months (P = 0.021). There was a statistically significant association between baseline depression and the worse 1-year SF-36. Patients with baseline depression had poorer 1-year DASH scores (20 ± 2.3) than nondepressed patients (11 ± 1.3) (P = 0.0031), and less improvement in DASH scores over the first year (P = 0.023). Multivariable linear regression demonstrated that baseline depression is the strongest predictor of poorer 1-year DASH scores (3.7, P = 0.0078) and change in DASH scores over the first year (2.9, P = 0.026). CONCLUSIONS: Baseline depression predicts worse function and disability outcomes 1 year from injury. Depression (CES-D ≥16) is the strongest predictor of worse 1-year DASH scores and SF-36 outcome measures, after controlling for other potential predictors. LEVEL OF EVIDENCE: Prognostic Level I.
