Radiation Exposure From Computed Tomography Of The Upper Limbs.

To investigate exposure to radiation we identified a cohort of 312 patients who underwent standardized CT of an upper limb within a three years period. The effective dose per dose length product coefficient was used to calculate the effective doses of radiation. Mean effective doses were as follows: shoulder CT, 10.83 (SD 6.36) mSv; wrist CT, 0.15 (SD 0.07) mSv; elbow CT performed with the arm above the head, 0.21 (SD 0.11) mSv and with the arm adjacent to the torso, 13.1 (SD 10.8) mSv. The corresponding lifetime attributable risk of cancer was 0.6/1000 for males and 0.73/1000 for females for shoulder CT and 0.75/1000 for males and 0.96/1000 for females for elbow CT with the arm adjacent to torso. The effective doses for CT scans of the wrist and of the elbow performed with the arm above the head were low. For elbow CT scans, elevating the arm above the head decreases the radiation doses.

Conservative treatment for pyogenic flexor tenosynovitis: a single institution experience.

Pyogenic flexor tenosynovitis (PFT) of the hand is a common infection which is clinically diagnosed using Kanavel's signs. Delay in diagnosis and treatment may lead to devastating outcomes, including reduced range of motion (ROM), deformities, tendon impairment or even amputation. While the gold standard for treatment is irrigation and debridement of the flexor sheath, little is known about the outcomes of conservative treatment with intravenous (IV) antibiotics. Patients treated conservatively for PFT between 2000 and 2013 were included. Demographic information, co-morbidities and clinical features at presentation such as Kanavel's signs and inflammatory markers levels were gathered. Treatment course, length of stay (LOS), functional outcomes and complications were collected. Fifty-four (54) patients presented with PFT in the study period. Forty-six (46) patients, ages 19-84 years old, who were treated conservatively were included. Average time from symptoms onset to presentation was 4.6 ± 7.1 days. Fourteen (14) patients failed to improve with course of oral antibiotics prior to presentation. The average number of Kanavel's signs was 3 ± 0.7. Inflammatory markers were elevated in 82.2% of patients. The mean LOS was 4.7 ± 2 days. Forty-four (44) patients continued follow-up for 55 ± 45 months. Final flexion ROM was full or minimally limited in 69% of patients. Three patients were eventually operated. Complication rate for the entire cohort was 4.3% and no fingers were lost. This retrospective case series indicate that inpatient empirical IV antibiotic therapy can be considered for patients presenting with uncomplicated PFT, provided it is practiced under a hand specialist's surveillance.

Soft-Tissue Surgery for Camptodactyly Corrects Skeletal Changes.

BACKGROUND: This study demonstrates the potential for radiographic and clinical improvement with surgical correction of camptodactyly. Although historically these radiographic changes have been held to be permanent, the authors encourage surgical intervention for digits with severe flexion contracture or progressive radiographic changes before skeletal maturity is reached. METHODS: The authors assessed 18 consecutively operated fingers in nine skeletally immature patients in whom advanced radiographic articular changes had occurred. Mean preoperative flexion contracture was 63 degrees (range, 35 to 105 degrees). The average age of the patients was 11 years (range, 4 to 15 years) at the time of surgery. Clinical response to surgery was studied, but radiographic articular changes were followed postoperatively as a primary outcome. RESULTS: Each patient demonstrated the classic preoperative radiographic joint changes on radiographic films at the affected proximal interphalangeal or distal interphalangeal joint. All patients had substantial clinical improvement postoperatively. Two digits had extensive radiographic damage, requiring proximal interphalangeal joint arthrodesis. Fifteen of the remaining 16 digits (94 percent) had substantial improvement or full restoration of radiographic articular congruency at average follow-up of 9 months (range, 3 to 18 months). The only joint that did not remodel fully was the one that did not have complete clinical correction. CONCLUSIONS: Even in patients with severe radiographic changes from camptodactyly, surgery can effectively improve range of motion. Once radiographic articular changes become apparent, surgical correction should be undertaken not only to prevent further joint damage but also to reverse these radiographic changes before skeletal maturity is reached. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
