Impact of Variation of Corticosteroid Dose, Injection Site, and Multiple Injections on Blood Glucose Measurement in Diabetic Patients.

PURPOSE: This study examined how corticosteroid dose, injection site location, and patient demographics affect blood glucose level after corticosteroid injection in diabetic patients. METHODS: We prospectively enrolled 70 patients with diabetes mellitus requiring upper- and/or lower-extremity corticosteroid injections. Patients measured fasting and postprandial blood glucose for 14 days after the injection. Blood glucose from days 1 through 7 was compared with the average of days 10 through 14, acting as control. Changes in blood glucose were compared by corticosteroid dose, injection location, patient demographics, and insulin use. RESULTS: Patients who underwent shoulder, wrist, or hand injections and patients who received multiple injections had no significant elevations in fasting or postprandial blood glucose, whereas those with knee injections had a significant increase in fasting blood glucose on postinjection days 1 and 2. Preinjection hemoglobin A1C had a significant effect on postinjection blood glucose whereas corticosteroid dose, body mass index, insulin use, and the number of injections had no significant effect on the elevation of blood glucose. There were no cases of diabetic ketoacidosis in any subjects. CONCLUSIONS: Patients receiving corticosteroid injections in the upper extremity did not experience significant increases in blood glucose whereas those undergoing knee corticosteroid injections demonstrated elevated blood glucose levels. Because poorer glucose control was associated with greater elevations in blood glucose after injection, patients with higher hemoglobin A1C should be counseled to monitor postinjection glucose more closely.

Arthroscopic Partial Trapeziectomy With Soft Tissue Interposition for Symptomatic Trapeziometacarpal Arthritis: 6-Month and 5-Year Minimum Follow-Up.

PURPOSE: To determine if arthroscopic partial trapeziectomy (APT) and soft tissue interposition arthroplasty is an effective treatment for symptomatic trapeziometacarpal arthritis. METHODS: We retrospectively evaluated 30 consecutive patients with symptomatic isolated trapeziometacarpal arthritis, Eaton-Littler stages II and III. Treatment consisted of an APT with soft tissue interposition utilizing an acellular dermal matrix as the interposition material. At a minimum of 6 months and 5 years after surgery, Numeric Pain Rating Scale (NPRS), Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), grip strength, oppositional and appositional pinch strengths, arthroplasty space, and thumb range of motion (ROM) were evaluated. RESULTS: At 6-month minimum follow-up, 30 of 30 patients reported a significant reduction in pain; preoperative NPRS averaged 8.2 and decreased to 1.3. Average QuickDASH score was 17.5. Twenty-nine of 30 thumbs could adduct fully in the plane of the palm. Twenty-four patients were available for 5-year minimum follow-up. Average QuickDASH score measured 8.9, whereas pain (mean NPRS, 0.8), grip, and pinch strengths were not significantly different from the 6-month assessment. There was a small reduction in arthroplasty space at 5-year follow-up that did not affect clinical outcome measures. Thumb ROM did not change between the 6-month and the 5-year follow-up. Complications were rare. CONCLUSIONS: An APT with interposition arthroplasty utilizing an acellular dermal matrix as the interposition material is a safe and reliable procedure with satisfactory outcomes at short- and long-term follow-up. Pain, strength, QuickDASH, and ROM do not significantly change between the 6-month and the 5-year follow-up. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Olecranon Fracture through Persistent Olecranon Apophysis in a 21-Year-Old Male: A Case Report and Systematic Review of the Literature.

Traumatic fractures involving an ununited olecranon apophysis in adults have been rarely documented in the literature. We present the case of a 21-year-old male wrestler with an elbow injury after a fall. Imaging revealed an acute fracture of the olecranon with sclerotic rounded edges indicating an injury through a persistent olecranon apophysis. Open reduction and internal fixation was performed with plate fixation and bone grafting with radiographic and clinical healing at 6 weeks. Review of the literature revealed 5 case reports showing high rates of non-union with tension band constructs while plate and screw fixation had no incidence of nonunion. Fractures through an ununited olecranon apophysis are successfully treated with plate and screw fixation with bone grafting.

Developmental Trigger Thumb.

Developmental trigger thumb, although uncommon, can be easily identifiable in the pediatric outpatient visit. Patients often present with their thumb locked in flexion and a firm nodule at the base of the thumb. The thumb is usually passively correctable and nonpainful. It is important to examine the opposite thumb as bilateral trigger thumbs occur at a rate of 25% to 30%. Nonsurgical options have been proposed in the past including watchful waiting, extension exercises, splinting, and steroid injections with mixed results. Surgical intervention is indicated when there is painful triggering or the thumb is not passively correctable. Surgical treatment is an outpatient procedure that involves releasing the thumb flexor tendon from a small fibrous sheath called the A1 pulley. The overall recurrence rate after surgery is 1.4%. Our recommendation is for early referral to a pediatric orthopedic surgeon to evaluate for the need for surgical intervention.
