Comparison of the Effects of Regular Periods of Immobilization and Prolonged Immobilization on Hand Function Post Distal Radial Fracture

IntroductionDistal radius fracture (DRF) is one of the most common orthopedic cases managed in the emergency room. DRF treatment is either non-operative or operative. Regardless of the treatment methodology, a period of immobilization of 4-6 weeks is required.PurposeThe study aims to evaluate hand function for patients who sustained DRF with different immobilization periods in King Abdul-Aziz Medical City, National Guard Hospital - Jeddah (NGHA) from December 2016 until December 2019.Materials and methodsThis is a retrospective cohort study where we collected data of DRF patients managed in NGHA. Data was collected directly from NGHA medical records (December 2016-December 2019). A total of 44 patients met the inclusion criteria. Patients were divided into two groups; a group that was immobilized as per protocol (six weeks) and a group that deviated from protocol and immobilization exceeded six weeks. A data collection sheet included the patient’s demographics, history, fracture description, management method, and hand function measurements.ResultsOf the 44 participants, 24 (54%) deviated from protocol; the remaining 20 (46%) were immobilized as per protocol. The prolonged immobilization group had limitations in hand function, restriction in extension (P-value = 0.641), and a decrease in grip strength (P-value = 0.291) compared to the per-protocol group. Flexion and radial deviation were affected similarly in both groups.ConclusionAlthough the results were not significant, immobilization for more than six weeks is associated with decreased hand function, range of motion (ROM), grip strength, and higher pain scores based on occupational therapy (OT) measurements.
