“…In this meta-analysis, the incidence of post-CTR TF was calculated based on the individual-based counting method in the five included studies, which reported a total of 9207 CTR surgeries and 827 cases of TF, resulting in an overall incidence of 7.7% (range: 5.2–12.2%). Many studies have reported the association between CTR and TF, but the spontaneous consent rate for carpal tunnel syndrome and TF ranged from 9.76 to 61% 2 , 9 , 30 , which was relatively wide and imprecise. Therefore, we determined the causal relationship between CTR and TF.…”

Introduction: Trigger finger (TF) often occurs after carpal tunnel release (CTR), but the mechanism and outcomes remain inconsistent. This study evaluated the incidence of TF after CTR and its related risk factors. Materials and Methods: PubMed, Embase, and Scopus databases were searched up to 27 August 2022, with the following keywords: “carpal tunnel release” and “trigger finger”. Studies with complete data on the incidence of TF after CTR and published full text. The primary outcome was the association between CTR and the subsequent occurrence of the TF and to calculate the pooled incidence of post-CTR TF. The secondary outcomes included the potential risk factors among patients with and without post-CTR TF as well as the prevalence of the post-CTR TF on the affected digits. Results: Ten studies with total 10,399 participants in 9 studies and 875 operated hands in one article were included for meta-analysis. CTR significantly increases the risk of following TF occurrence (odds ratio=2.67; 95% CI 2.344–3.043; P<0.001). The pooled incidence of TF development after CTR was 7.7%. Women were more likely to develop a TF after CTR surgery (odds ratio=2.02; 95% CI 1.054–3.873; P=0.034). Finally, the thumb was the most susceptible fingers, followed by middle and ring fingers. Conclusions: High incidence of TF comes after CTR, and women were more susceptible than man. Clinicians were suggested to notice the potential risk of TF after CTR in clinical practice. Level of evidence: Level III, meta-analysis.

Background Posterior femoral cutaneous nerve (posterior cutaneous nerve of the thigh) is a sensory nerve arises from the sacral plexus. Its terminal part supplies the skin of the posterior surface of the thigh and popliteal fossa, and it extends for a variable length below the popliteal fossa till the mid-calf region. The aim was to assess the posterior femoral cutaneous nerve antidromic sensory conduction technique and estimate its different sensory nerve action potential parameters’ reference values in a sample of apparently healthy Egyptian participants. One hundred and twenty lower limbs of 60 apparently healthy Egyptian volunteers were included. Clinical evaluation and sensory conduction study for the posterior femoral cutaneous nerve were done. Results Posterior femoral cutaneous nerve sensory nerve action potential was elicited in 98 lower limbs (81.6%) of 52 individuals (86.7%). The obtained results of different parameters of posterior femoral cutaneous nerve sensory nerve action potential were as the following: onset latency (2.04 ± 0.21 ms), peak latency (2.86 ± 0.25 ms), conduction velocity (59.45 ± 6.36 m/s) and amplitude (6.16 ± 2.29 μV). No significant differences between the two genders were found regarding different parameters of posterior femoral cutaneous nerve sensory nerve action potential except for amplitude which was significantly larger among male participants (P = 0.030). No significant differences between the right and left lower limbs were found regarding different parameters of sensory nerve action potential. There was a statistical significant negative correlation between age and posterior femoral cutaneous nerve conduction velocity (P = 0.008). There was a statistical significant positive correlation between height and peak latency (P ≤ 0.0001), as well as, a statistical significant negative correlation between height and conduction velocity (P ≤ 0.0001). There was a statistical significant negative correlation between body mass index and posterior femoral cutaneous nerve peak latency (P = 0.008). Conclusions The research provides a reliable electrophysiological antidromic sensory conduction study for the posterior femoral cutaneous nerve and normal cut-off reference values for posterior femoral cutaneous nerve sensory nerve action potential parameters. This is essential for the evaluation of suspected posterior femoral cutaneous nerve lesions.

Background: Carpal tunnel syndrome and trigger finger are common hand problems. Each can be a cause of pain and disability. Treatment for each diagnosis can be nonoperative or, when nonoperative treatment has failed and when symptoms warrant, treatment can be surgical. Carpal tunnel syndrome and trigger finger can present independently of each other, or, in some cases, both can be present in the same hand. Methods: Data was collected using PearlDiver proprietary software (PearlDiver, Inc, Colorado Springs, CO). This is a national data set from the United States representing 157 million distinct patients over the period from January 2010 to October 2021. PearlDiver was queried for all patients who underwent carpal tunnel release (represented by CTP-64721 for open carpal tunnel releases and CTP-29848 for endoscopic releases) and trigger finger release (represented by CTP-26055) on the same day. Results: Our search identified the number of carpal tunnel releases and the number of carpal tunnel releases + trigger finger release (same day). Carpal tunnel release + trigger finger release represent 8.4% of the total number of carpal tunnel release procedures. Conclusion: Patients who present with carpal tunnel syndrome may be advised that they are at increased risk of developing trigger fingers.
