Radius palmar plate removal without carpal tunnel release: Correlation between plate position and median nerve symptoms.

We aimed to report the clinical results of volar plate removal without carpal tunnel release in patients with late-onset median neuropathy and to evaluate the relationship between plate position and median nerve symptoms. Part I. Twelve consecutive patients with late-onset median neuropathy treated with volar plate removal without carpal tunnel release were enrolled for analysis. Pre- and post-operative Tinel sign, Phalen and Ten test, subjective rating of tingling sensation, Mayo wrist score and Disabilities of the Arm, Shoulder and Hand (DASH) score were collected. Part II. 232 consecutive patients underwent volar plating for distal radius fracture. The relationships between median nerve symptoms and volar plate prominence on the Soong classification, fracture classification, gender and age were investigated. All cases except one showed complete symptom resolution at final follow-up, with negative Tinel sign and Ten test score of 10/10. Tingling was rated 0 at final follow-up. Mean Mayo wrist and DASH scores improved to 86.7 and 23.1, respectively. The incidence of the median nerve symptoms in our cohort was 5.6%. Even though the odds ratio in Soong grade 2 was 4.0957 (95% CI, 0.93-16.9) compared to the combination of grades 0 and 1, no statistically significant relationship was found between the median nerve symptoms and volar plate prominence (p > 0.05). Plate removal without carpal tunnel release adequately relieved symptoms of late-onset median neuropathy after volar plating in patients with distal radius fracture. LEVEL OF EVIDENCE: IV; Therapeutic.

Flexor tendon rupture after volar plating of distal radius fracture: A systematic review of the literature.

Flexor tendon rupture after volar plate fixation of distal radius fracture (DRF) is rare. There is no consensus as to how to prevent them. The aim of our study was to identify the pathological mechanisms, and to establish the clinical and epidemiological profile of patients suffering from this complication. We carried out a systematic review using the PubMed, Scopus and Cochrane databases. Studies were included if they described complete or partial flexor tendon rupture following volar plate fixation of DRF. Forty-six 46 were included, for a total of 145 patients were reported: 138 from the literature, and 7 from our personal experience. Etiology was usually mechanical, by impingement with either the plate or protruding screws. Plate impingement was due to positioning beyond the watershed line, consolidation with posterior tilt, plate thickness, or low palmar cortical angle. Mean patient age was 62.4 years (range, 23-89 years). Median postoperative interval was 8 months (range, 3-120 months). Flexor pollicis longus was the most frequently injured tendon. The plate should be positioned proximally to the watershed line if possible, to ensure good initial reduction. Hardware should be removed 4 months after surgery if the plate is causing impingement according to the Soong criteria or if signs of tenosynovitis appear.

Combined volar and dorsal plating vs. volar plating of distal radius fractures. A single-center study of 105 cases.

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.

Can an adipofascial flap be used to prevent adhesions after plating of the proximal phalanx? A case report.

Tendon adhesions in zone IV after proximal phalangeal fractures are common and may lead to loss of range of motion at the proximal interphalangeal joint. The type of fracture, surgical technique and rehabilitation strategy also influence the final functional outcome. Plate fixation is a reliable solution in cases of comminuted phalangeal fracture. This article describes how adhesions between the plate and extensor apparatus in cases of comminuted fractures of the proximal phalanx can be reduced by using an adipofascial flap.
