Carpal tunnel syndrome is associated with increased intracarpal canal pressure. The effect of tendon loading on intracarpal canal pressures is documented in biomechanical studies. Palmaris longus loading in wrist extension induces the greatest absolute increase in intracarpal canal pressure. Despite this fact, the palmaris longus is not yet a proven independent risk factor for the development of carpal tunnel syndrome. The purpose of this prospective clinical study was to assess and quantify the association between the presence of a palmaris longus tendon and carpal tunnel syndrome. Thirty-six carpal tunnel subjects with bilateral disease were compared with 36 controls. Each subject was clinically examined for the presence of the palmaris longus tendon. The prevalence of palmaris longus agenesis was significantly lower in the carpal tunnel group. The palmaris longus tendon is a strong independent risk factor for carpal tunnel syndrome.

Abstract Background The palmaris tendon inserts into the palmar fascia and is positioned in close association with the transverse carpal ligament. Loading of this tendon has been demonstrated to increase carpal tunnel pressures. Purpose The purpose of this study was to determine if a relationship exists between the palmaris tendon, carpal tunnel syndrome (CTS), and handedness. The sensitivity, specificity, positive predictive value, and negative predictive value for Schaeffer's test were calculated. Methods A retrospective review of patient charts undergoing endoscopic carpal tunnel release was performed. Rates of palmaris longus agenesis (PLA) were compared to a population matched data set. Statistical analysis was performed using a one-proportion z-test. Schaeffer's test for the palmaris longus tendon was performed on all patients and compared to intraoperative confirmation. Results A total of 520 carpal tunnel releases were performed in 389 consecutive patients. The frequency of PLA in this surgical cohort was significantly lower compared to the population matched dataset. No correlation between handedness and laterality of CTS or PLA was found. Schaeffer's test was evaluated to yield sensitivity (93.6%), specificity (100%), positive predictive value (100%), and negative predictive value (50.8%). Conclusion The palmaris tendon was more prevalent in a population of patients undergoing carpal tunnel release. These findings can be used to provide further insight into the pathophysiology of CTS. While Schaeffer's test was accurate in detecting the palmaris longus tendon, a negative test was frequently incorrect. Further imaging is recommended in patients with a negative Schaeffer's test when the palmaris longus is desired for surgical utilization. Level of Evidence This is a Level III, prognostic study.

Steroid injections are routinely performed for carpal tunnel syndrome. Direct needle injury of the median nerve is the major complication of these injections. The safest location of the injection remains controversial. The purpose of this study is to define safe guidelines to avoid nerve injury. The distances between the Median nerve, Palmaris Longus, Flexor Carpi Ulnaris and Flexor Carpi Radialis tendons were measured preoperatively, 1 cm proximal to the distal wrist crease in 93 endoscopic carpal tunnel releases. We found that the median nerve extended ulnarly beyond the Palmaris Longus tendon in 82 hands (88%). It is concluded that the median nerve is at risk if the injection is performed within 1 cm on either the ulnar or radial side of the Palmaris Longus tendon. More ulnarly, there is risk to the ulnar pedicle. The safest location is to inject through the FCR tendon.

Carpal tunnel release is a routinely performed operation to relieve pressure caused by compression on the median nerve. In the majority of cases, the causation of the compression will be idiopathic. Among the secondary causes of median nerve compression is the palmaris profundus, a rare anatomical variant separate to the palmaris longus tendon. It has been suggested that it may cause carpal tunnel syndrome as it courses underneath the flexor retinaculum with the contents of the carpal tunnel reducing the space available to the median nerve. Several cases have found it intimately associated with the median nerve within the carpal tunnel. Raising awareness of this anatomical variant is therefore important for those undertaking carpal tunnel decompression in order to avoid unintended damage.

Background A paucity of literature exists specifically examining self-inflicted (SI) gunshot wounds (GSWs) to the hand and wrist, which impart greater energy and have a higher risk of adverse events than non–self-inflicted (NSI) GSWs. Methods We retrospectively reviewed records of patients who presented to our plastic surgery service after sustaining acute GSWs involving the hand and wrist between 2016 and 2018. Results We identified 60 patients who sustained GSWs involving the hand and wrist; 17 (28%) were SI, and 43 (72%) were NSI. Within the SI group, 100% of patients were Caucasian, with an average age of 54 years. Within the NSI cohort, 77% of patients were Black, 19% were Caucasian, and 4% identified as other. While not statistically significant, we noted a substantial increase in patients requiring operative intervention in the SI cohort (65% SI vs 37% NSI, P = .08). There was a statistically significant increase in patients requiring more than 1 operation in SI patients (24% SI vs 5% NSI, P = .04). Patients who sustained SI injuries were also more likely to present with acute carpal tunnel syndrome requiring urgent surgical release and to develop wound infections (12% vs 0%, P = .08). Conclusions Self-inflicted GSWs involving the hand and wrist are associated with greater morbidity than their low-energy NSI counterparts. Individuals presenting with SI GSWs are more likely to be older, to require multiple operations, to develop infections, and to present with acute carpal tunnel syndrome requiring urgent surgical decompression.
