“…The PLT is located just above the FDSM and just under the fascia of the forearm, the subcutaneous fat. [14,15] Therefore, to assess the relationship between the PLT and CTS, we newly made the measurement of the palmaris longus tendon cross-sectional area (PLTCSA). Moreover, no previous researches have assessed the clinical best cut off value of PLTCSA.…”

Carpal tunnel syndrome (CTS) is correlated with increased intracarpal canal pressure (ICP). The effect of palmaris longus tendon (PLT) loading on ICP is documented in previous researches. PLT loading induces the greatest absolute increase in ICP. Therefore, to analyze the connection between the PLT and CTS, we newly made the measurement of the PLT cross-sectional area (PLTCSA). We assumed that PLTCSA is a reliable diagnostic parameter in the CTS. PLTCSA measurement data were acquired from 21 patients with CTS, and from 21 normal subjects who underwent wrist magnetic resonance imaging (W-MRI). We measured the PLTCSA at the level of pisiform on W-MRI. The PLTCSA was measured on the outlining of PLT. The two different cutoff values in the analysis were determined using receiver operating characteristic (ROC) analysis. The mean PLTCSA was 2.34 ± 0.82 mm2 in the normal group and 3.97 ± 1.18 mm2 in the CTS group. ROC curve analysis concluded that the best cutoff point for the PLTCSA was 2.81 mm2, with 76.2% sensitivity, 71.4% specificity, and area under the curve of 0.88 (95% CI, 0.78‐0.98). PLTCSA is a sensitive, new, objective morphological parameter for evaluating CTS.

“…There is wide variation in the reported prevalence and anatomical characteristics of PLM in different ethnic groups [2,4,8,10,12,15,19]. Reimann et al 1944 first classified PLM variations [17,18]. PLM anatomical variation classifications include reversed (palmaris longus inversus muscle or PLIM), duplicated, triplicated, bifid, hypertrophied, accessory (additional) slips, and/or complete absence [1][2][3][4]6,[8][9][10][11][13][14][15][16][17][18][19][20][21][22].…”

The palmaris longus muscle is one of the most variable muscles in the human body. Palmaris longus muscle anatomical variations include reversed (palmaris longus inversus muscle), duplicated, triplicated, bifid, hypertrophied, accessory (additional) slips, and/or complete absence. During anatomical dissection of fifty cadavers in the 2019 undergraduate first-year anatomy course at the Uniformed Services University of the Health Sciences, we found a palmaris longus inversus muscle bilaterally on an 82 year-old White female cadaver and a unilateral palmaris longus inversus muscle on the right forearm of a 68 year-old White female cadaver. Due to the prevalence of anatomical variations in the palmaris longus muscle, adequate knowledge of such prevalence and clinical significance is needed in multiple medical specialties for its reconstructive use, and the possibility and treatment of clinical syndromes. An accessory (additional) palmaris longus muscle, hypertrophied palmaris longus muscle, hypertrophied palmaris longus inversus muscle, or just the presence of a palmaris longus inversus muscle, can all cause compression to adjacent neurovascular structures, such as the median nerve, ulnar nerve, ulnar artery, and/or the anterior interosseous artery, in the distal forearm and wrist. Palmaris longus tendons are used as grafts in various surgeries, such as extensor tendon repair in rheumatoid arthritis patients, injuries of flexor tendons and repair, lip augmentation, reconstructive hand surgery, frontalis suspension sling in ptosis correction, plastic surgery, and pulley reconstructions. Surgeons, physicians, radiologists, and physiotherapists must be knowledgeable of the many PLM anatomical variations and their possible contributions to pathological processes.
