The aim of this study was to know if applying continuous passive motion (CPM) in addition to routine exercises is more effective than routine exercises alone in pain reduction, range of motion (ROM) and function improvement after distal radius fractures (DRFs). In this randomized controlled trial, 21 patients with non-stabilized DRF after pin removal were randomly assigned to experimental and control groups. The experimental group received stretching exercises with CPM machine for 2×15min per session. Both groups received routine exercises for 1h, three times a week for 4 weeks. The primary outcome measure was pain evaluated on a visual analog scale (VAS), and the secondary outcome measures were disability evaluated by the patient-rated wrist/hand evaluation and ROM (goniometry) at 4, 6, and 12 weeks. Univariate analysis of covariance (ANCOVA) and a one-way repeated measure mixed model analysis of variance (ANOVA) were used for data analysis. Twenty-one participants completed the 12-week follow-up. Pain relief, ROM and functional improvement revealed that the treatment was successful in both groups. We detected no significant differences (p>0.05) between the two groups at the end of the follow-up period regarding pain, ROM, and function. Using a CPM machine had no additional effect on pain reduction, ROM and function improvement compared with routine exercises in patients with DRF.

Despite recent advances in the surgical management of distal radius fractures (DRFs), the optimal treatment remains controversial as different fixation methods often have similar clinical functional and radiographic outcomes. The objective of this study was to assess the differences in outcomes 1 year postoperatively between volar plating and combined plating for DRFs. In a retrospective cohort study, we evaluated 105 consecutive patients operated with either a volar locking plate or combined dorsal and volar plating. The primary outcome was wrist range of motion (ROM). Secondary outcome measures included hand grip strength, visual analog scale (VAS) pain scores, radiographic examination and patient-related outcome measures. Patients treated with combined plating had significantly inferior wrist flexion, extension and ulnar deviation. The radiographic Batra score 1 year postoperatively was similar for both groups. The PRWE (patient-rated wrist evaluation) score was 16 for the volar plating group and 14 for the combined plating group. The QuickDASH (Quick disabilities of the arm, shoulder and hand) score was 9 for the volar plating group and 16 for the combined plating group. VAS pain scores were 0 at rest and 2 during activity for both groups. Grip strength was similar between the two groups. Hardware removal was done in 18/78 patients for the combined plating group and 1/27 for the volar plate group. Two patients operated with combined plating had tendon ruptures. Our findings indicate that both methods can yield satisfactory clinical and radiographic outcomes. However, combined plating resulted in inferior wrist ROM and substantially higher frequency of hardware removal. The potential advantages of combined plating in stabilizing a comminuted DRF must be balanced by the potential drawbacks such as inferior wrist ROM and higher frequency of hardware removal.

We sought to investigate the effects of early manual therapy on functional outcomes in patients treated with volar plating of a distal radius fracture (DRF). This was a prospective, single-blinded, randomized controlled trial. Patients treated with volar plating of a DRF were randomly assigned to either Early Manual Therapy Group (EMTG, n=19) or Standard Physiotherapy Group (SPG, n=20). While SPG received standard physiotherapy, EMTG received standard physiotherapy plus Mulligan\'s Mobilization with Movement technique two sessions a week, through 12 weeks. Function, pain intensity, range of motion, grip strength and the level of disability were assessed using the Patient Rated Wrist Evaluation (PRWE), Visual Analog Scale (VAS), goniometer, hand dynamometer and Disabilities of Arm, Shoulder and Hand (DASH) Questionnaire, respectively. Measurements were made at 3, 6, and 12 weeks postoperatively. Of the 54-screened patients, 39 met the inclusion criteria and were randomized. In total, 32 patients (EMTG, n=15; SPG, n=17) were analyzed. EMTG had significantly better DASH score and wrist flexion at 12 weeks, less pain and better PRWE total score, wrist extension, ulnar/radial deviation, supination and grip strength at all time points. Moreover, wrist flexion increased more with the addition of early manual therapy than standard physiotherapy alone (26.50±13.19 versus 16.21±16.06). The addition of early manual therapy to standard physiotherapy may contribute to better functional outcomes and be more effective in increasing wrist flexion in patients treated with volar plating of a DRF.

Distal radius fractures (DRF) may trigger, reveal or decompensate acute carpal tunnel syndrome (CTS) in 0.5-21% of cases. Internal fixation and median nerve release must then be carried out urgently. Less invasive approaches have been described for both the median nerve release using an endoscopic device and for the DRF fixation using a volar locking plate. We assessed the feasibility of DRF fixation and median nerve release through a single, minimally-invasive 15mm approach on a series of 10 cases. We reviewed retrospectively 10 consecutive cases of DRF associated with symptomatic CTS in 8 women and 2 men, aged 57 years on average. CTS was diagnosed clinically. All patients were treated during outpatient surgery with a volar locking plate and endoscopic carpal tunnel release using a single 15mm minimally-invasive approach. In one case, arthroscopic scapholunate repair was also required. Six months after the procedure, all patients were reviewed with a clinical examination and a radiological evaluation. The average values for the clinical and radiological outcomes were as follows: pain on VAS 1.5/10; QuickDASH 14.3/100; flexion 90%; extension 90.6%; pronation 95.6%; supination 87.9%; grip strength 90.1%; 2PD test 5.2mm (4-8mm). Five complications occurred: two cases of temporary dysesthesia in the territory of the median nerve and one case of temporary hypoesthesia of the palmar branch of the median nerve, which had all completely recovered; two cases of complex regional pain syndrome type I, which were still active at 6 months. Despite its methodological weaknesses, our study is the only one to describe the technical feasibility of a single 15mm minimally-invasive approach for both internal fixation using a volar locking plate and endoscopic nerve release, with no serious complications. This technique should be added to the surgical toolbox of minimally-invasive procedures for the hand and wrist.
