A Prospective Analysis of Patient Characteristics Affecting the Outcome of Dorsal Splinting for Soft Tissue Mallet Injuries.

BACKGROUND: Much has been written about the diagnosis and treatment of soft tissue mallet injuries. However, there has been little regarding the characteristics of this injury affecting patients' prognosis. The purpose of this prospective study was to identify factors influencing the outcome of treatment of soft tissue mallet injuries. METHODS: Patients diagnosed with soft tissue mallet injuries were enrolled prospectively in a protocol of dorsal splinting for 6 to 12 weeks, followed by weaning over 2 weeks and then evaluated at 6, 9, and ≥12 months. RESULTS: Thirty-seven patients (38 digits) completed the study. Treatment success was defined as a final extensor lag of <15° and failure as a final extensor lag of ≥15°. Those failing splint treatment were older compared with those successfully treated. Patient compliance was significantly associated with a successful outcome. Factors that did not significantly affect success included time to treatment, initial injury severity, splinting duration, sex, and ligamentous laxity. Disabilities of Arm, Shoulder, and Hand scores >0 were not associated with treatment failure. Radiographic and clinical extension lag were statistically comparable. CONCLUSIONS: This study shows strong association between the success of splint treatment, younger patient age, and compliance with the treatment protocol. Despite this finding, most patients did not report any functional limitations, irrespective of the treatment success. In contrast to prior results, time to treatment and initial extensor lag did not significantly affect treatment success.

Impact of prior gestational diabetes on long-term type 2 diabetes complications.

AIMS: While women with gestational diabetes mellitus (GDM) have a higher risk of developing type 2 diabetes mellitus (T2DM) and at a younger age, it is unknown whether T2DM following GDM is associated with worse clinical outcomes. This study aims to examine the impact of GDM on subsequent development of long-term complications of T2DM. METHODS: All women with T2DM from the National Health and Nutrition Examination Survey (NHANES), a nationally representative cross-sectional survey of US population, between 2007 and 2018 (n = 2494) were stratified into two groups: those with a history of GDM (n = 385) and those without (n = 2109). Rates of macrovascular and microvascular complications of T2DM were compared between the two groups using bivariate and multivariate analyses. RESULTS: Of 2494 participants with T2DM included in the analysis, 385 (15.4 %) had a history of GDM and 2109 (84.6 %) did not. A history of GDM was independently associated with increased risk of myocardial infarction (aOR 2.53, 95%Cl: 1.18-5.40) and likely coronary artery disease (aOR 2.15, 95 % Cl: 1.00-4.66). CONCLUSIONS: In this cohort, women with T2DM and a history of GDM had higher risk of macrovascular complications of myocardial infarction and coronary artery disease, compared to those with no history of gestational diabetes.

Implant survival and patient-reported outcomes after total hip arthroplasty in young patients with developmental dysplasia of the hip.

BACKGROUND: Developmental dysplasia of the hip (DDH) is a common cause of hip pain in young patients, and may require treatment with total hip arthroplasty (THA). This study evaluates implant survival and describes patient-reported outcomes after primary THA in DDH patients aged 35 or younger. METHODS: A retrospective study with prospective follow-up was conducted at a major academic medical centre. Patient charts were reviewed to identify young THA patients with DDH, and follow-up surveys were conducted to determine implant survival and patient-reported outcomes. Kaplan-Meier survival analysis was performed to evaluate implant survival, and the hip disability and osteoarthritis outcome score (HOOS) was used to describe patient-reported outcomes. RESULTS: This study included 61 patients (75 THAs, 75% follow-up), and the mean time to follow-up was 13 years (range 3-25 years). The 10-year and 20-year implant survival was 87% (95% CI, 78%-94%) and 55% (95% CI, 37%-72%), respectively, and implant survival was significantly better in patients over the age of 25 at the time of surgery (p value <0.01). The mean HOOS patient scores were 83 for pain (SD 20.29), 78 for symptoms (SD 19.72), 83 for ADLs (SD 20.89), and 74 for sports (SD 25.92). Patients that were younger at the time of surgery or required custom implants reported worse HOOS-Symptom scores at follow-up (p value = 0.02). DISCUSSIONS: Young patients with DDH have good outcomes after surgery. Patient factors and implant characteristics should be considered when predicting implant survival and outcomes after THA in young patients with DDH.

Malpractice in distal radius fracture management: an analysis of closed claims.

PURPOSE: Distal radius fractures comprise the majority of hand- and wrist-related malpractice claims. We hypothesized that a majority of lawsuits would be for malunions resulting from nonsurgical treatment. Additional goals of this study were to quantify costs associated with claims, determine independent risk factors for making an indemnity payment, and illustrate trends over time. METHODS: Seventy closed malpractice claims filed for alleged negligent treatment of distal radius fractures by orthopedic surgeons insured by the largest medical professional liability insurer in New York State (NYS) from 1981 to 2005 were reviewed. We separately reviewed defendants' personal closed malpractice claim histories from 1975 to 2011. Overall incidence of malpractice claims among distal radius fractures treated in NYS was calculated using the NYS Statewide Planning and Research Cooperative System database and the 2008 American Academy of Orthopedic Surgeons census data. RESULTS: The overall incidence of malpractice claims for distal radius fracture management was low. Malunion was the most common complaint across claims regardless of treatment type. Claims for surgically treated fractures increased over time. A majority of claims documented poor doctor-patient relationships. Male plaintiffs in this group were significantly older than males treated for distal radius fractures in NYS. Most defendants had a history of multiple malpractice suits, all were male, and only a small percentage were fellowship-trained in hand surgery. Defendants lacking American Board of Orthopedic Surgery certification were significantly more likely to make indemnity payments. Thirty-eight of 70 cases resulted in an indemnity payment. CONCLUSIONS: Malunion and poor doctor-patient relationships are the major features of malpractice litigation involving distal radius fracture management. Older defendant age and lack of American Board of Orthopedic Surgery certification increase the likelihood of making an indemnity payment.

Steroid injections in the upper extremity: experienced clinical opinion versus evidence-based practices.

A survey regarding upper-extremity steroid injection practices was distributed to all active members of the American Society for Surgery of the Hand (ASSH) and American Shoulder and Elbow Surgeons (ASES) using SurveyMonkey. Response rates for the ASSH and ASES were 26% and 24%, respectively. The potency-adjusted dose of steroid injected for common hand and wrist injections ranged from 0.375 to 133.33 mg and for shoulder injections ranged from 0.375 to 250 mg. These ranges span 356-fold and 667-fold differences, respectively. Potency-adjusted doses differed significantly between steroid types for all injections evaluated in this study. American Society for Surgery of the Hand members gave significantly smaller doses of steroid for the glenohumeral and acromioclavicular joints than ASES members. Only 9% of respondents based injection practice on a scientific reference. Sixteen percent of ASSH and 31% of ASES respondents reported no specific rationale for their steroid injection practice; 78% of ASSH and 52% of ASES respondents attributed their rationale to some kind of instruction from their mentors or colleagues. Upper-extremity surgeons demonstrate substantial variability in their practice of steroid injections, with up to a 667-fold range in steroid dose. Experienced clinical opinion is the principal rationale for these injection practices; little rationale is based on formal scientific evidence.

Effect of local corticosteroid injection of the hand and wrist on blood glucose in patients with diabetes mellitus.

Locally administered corticosteroids are a common therapy in many hand and wrist disorders. Corticosteroids pose a theoretical risk to patients with diabetes mellitus by potentially raising blood glucose to hyperglycemic levels. Although oral corticosteroids are known to have an effect on blood glucose control, limited data exist on extra-articular administration. The purpose of this study was to examine the systemic impact of extra-articularly administered corticosteroids in the hand and wrist on serum glucose concentration in patients with diabetes mellitus.Twenty-three patients with diabetes mellitus received a 1-mL triamcinolone acetonide injection for de Quervain's tenosynovitis, trigger finger, flexor carpi ulnaris tendonitis, or carpal tunnel syndrome. Patients recorded their daily morning blood glucose levels for 1 week before injection and for 4 weeks after injection. Average blood glucose levels increased slightly from baseline after injection, reaching statistical significance 1, 5, and 6 days after injection, but were not clinically significant (average increase, 14.2, 9.7, and 32.7 mg/dL, respectively). Isolated increases more than 2 times the standard deviation of preinjection values occurred at least once in the majority of patients. The frequency of hyperglycemic episodes increased after injection, but the proportions of patients with at least 1 hyperglycemic episode before and after injection were not significantly different.These results suggest that local corticosteroid injections are a clinically safe treatment option for inflammatory processes of the hand and wrist in patients with diabetes mellitus. On average, patients experienced slight increases in blood glucose after receiving an injection. Most experienced isolated increases substantially beyond baseline and isolated hyperglycemic effects, but these did not pose an apparent clinical risk.
