[Conservative treatment of distal radial fractures].

objectiveDistal fracture of the radius is common in all age groups. Under careful consideration of individual indications and contraindications, conservative treatment with reduction and immobilization can have significant advantages over the frequently applied surgical approach, particularly in older patients. THERAPEUTIC GOAL: Immobilization after closed reduction enables satisfactory wrist function to be achieved according to individual patient expectations. INDICATIONS: A. Patients with a. significant comorbidities, b. high surgical risk from an anesthesiology perspective (ASA > 3), c. low functional requirements, d. low cosmetic expectations regarding residual visible deformity. B. Young patients with an extension fracture and additional a. < 10° dorsal tilt in the case of extraarticular fractures after closed reduction, b. < 5 mm radial shortening after closed reduction, c. < 2 mm intraarticular displacement after closed reduction. CONTRAINDICATIONS: A. Patient age < 65 years with an extension fracture and additional a. > 10° dorsal tilt in the case of extraarticular fractures after closed reduction, b. > 5 mm radial shortening after closed reduction, c. > 2 mm intraarticular displacement after closed reduction. B. Flexion fracture for which ligamentotaxis for closed reduction is not possible. C. Open distal radial fracture. D. Fracture dislocations. E. Impairments of peripheral circulation, motor or sensory function of the hand after reduction. TECHNIQUE: After puncturing the fracture hematoma and infiltrating the fracture gap with local anesthetic, the forearm is suspended using Chinese finger traps on the thumb and middle finger. Constant traction in the longitudinal axis of the forearm is ensured by a weight applied via a wide cushioned cuff to the distal upper arm. Reduction then is enabled with the additional reductive effect of ligamentotaxis. After minimal cushioning of the forearm with cotton wool and crepe bandage, a dorsal gypsum longuette is applied. After the plaster bandage has hardened, peripheral circulation, motor function, and sensitivity are checked. The reduction is controlled by X‑ray and documented. POSTPROCEDURAL MANAGEMENT: A. General procedures to reduce swelling; sufficient analgesics should be prescribed. B. The circular plaster cast is applied once swelling has subsided sufficiently, generally after 2-3 days. C. The duration of cast wearing should be planned at 5 weeks.

resultsA total of 73 patients (55 women and 18 men) aged 65-88 years were followed up for 12 months to investigate functional outcomes after surgical and conservative therapy. While surgical patients had better functional scores up to 12 weeks after treatment begin, there was no longer a significant difference in the 6‑ and 12-month follow-up results. The measured grip strength was consistently better in the surgically treated group. Clinically visible deformities were present in 78% of the conservatively treated patients; however, the patients were satisfied with the functional or cosmetic results. No deformities were seen in the surgically treated patients. All fractures were completely healed after 6 months. The rate of complications was significantly higher in the surgery group, with 13 complications compared to 5 in the conservative treatment group.
