PURPOSE: Lumbrical muscles of the upper limb belong to the middle group of intrinsic hand muscles. Their anatomical variability has been extensively studied with heterogeneous findings. Therefore, the aim of this study is to provide a systematic review and a meta-analysis of the lumbrical muscles variations in the human hand. METHODS: For this purpose, four major electronic databases were searched to identify eligible studies. Then, all relevant data were extracted, and statistical analysis performed. A new classification of lumbrical muscles variations is proposed to summarize and clearly define all described findings. We included 26 studies, making a total sample of 1340 dissected hands. FINDINGS: The most common variations for each muscle were an accessory belly for the first lumbrical muscle, a variable origin for the second lumbrical muscle, a variable innervation for the third lumbrical muscle and a variable insertion for the fourth lumbrical muscle with the prevalence 3.8%; 7.7%; 12% and 5.8%, respectively. CONCLUSIONS: We believe that results of our statistical analysis are suitable for both hand surgeons and other medical professionals dealing with hand injuries or functional problems in their daily routine.

PURPOSE: Knowledge of the unusual arrangement of the flexor pollicis longus (FPL) muscle is important as the variable tendon may be a rare cause of carpal tunnel syndrome. METHODS: During a routine dissection at the Department of Anatomy, an unusual formation of the FPL muscle was observed in a formalin embalmed Central European cadaver. RESULTS: This report presents a variation of the FPL muscle, where the muscle split and formed a separate accessory head inserting into the first lumbrical muscle. Moreover, a tendinous interconnection was present between the FPL muscle tendon and the tendon of the aberrant muscle head. CONCLUSION: The cases described by previous literature, concerning the Linburg-Comstock variation or the accessory head of the first lumbrical muscle originating from the FPL muscle, are closest to the present case. Such variation has a clinical significance ranging from the functional limitation of the thumb and index finger movement to the potential median nerve compression.
PURPOSE: Knowledge of accessory flexor carpi ulnaris (AFCU) is not only important for proper orientation in the surgical field but it can be used for tendon transfer as well. AFCU commonly occurs with concomitant variants, and its presence should rise caution in order to prevent iatrogenic injury. METHODS: During a routine dissection for research data collection at the Institute of Anatomy, a AFCU with concomitant variants was observed in a European cadaver fixed with Thiel's method. A thorough review of the literature concerning all the encountered variants was performed. RESULTS: AFCU was found in the right upper limb with its insertion on the flexor retinaculum. Palmaris longus muscle was absent in this limb, and an accessory branch of the anterior interosseous artery coursed over the pronator quadratus muscle to anastomose with the ulnar artery 5 cm proximally to the pisiform. On the left hand, a variable lumbrical of the second finger originating from the flexor retinaculum was found, which was not described in the literature before. CONCLUSIONS: AFCU commonly occurs together with concomitant variants, and special attention is needed when performing surgery on such forearm.

The book represents the second output of the same project that has produced "Musculoskeletal ultrasound in physical and rehabilitation medicine". Musculoskeletal ultrasound is user-dependent, thus it strongly needs training with a mentor and "maintenance" education.

Ulnární deviace prstů je součástí rozvinuté kolapsové deformity zápěstí a ruky. Porucha centrálního pilíře ruky začíná ulnární translokací karpu ve frontální rovině. Dle Shapirovy teorie se karpus a metakarpální krajina biomechanicky chovají jako celek a ulnární posun zápěstí a jeho inklinace radiálně je sledován radiální inklinací metakarpů a ulnární deviací prstů. V oblasti MCP kloubů vzniká vlivem uvolnění vazivového aparátu tendence k dislokaci průběhu extenzorových šlach II. až V. prstu ulnárně. Jejich sklouznutí z vrcholu MCP kloubu do intermetakarpálních prostorů má za následek omezení jejich extenční schopnosti. Extenzory se v novém, patologickém průběhu stávají i ulnárními duktory prstů a dále zesilují a fixují ulnární deviaci. Operační výkony, které vedou k zachycení posunu karpu ulnárně jsou prevencí vzniku kolapsové deformity a tím i ulnární deviace prstů. Základním výkonem je časná synovektomie dorzální části karpu a peritenosynovektomie extenzorových šlach doplněná šlachovou transpozicí, dále synovektomie MCP kloubů spolu s výkony, které reponují fyziologický průběh extenzorových šlach. Používají se i limitované dézy v proximální řadě karpálních kostí. Tonizace radiálních kolaterálních vazů a transpozice úponů ulnárních interoseálních a lumbrikálních svalů na radiální část základního článku vedlejšího prstu patří k nejsložitějším operačním výkonům v této krajině. Jejich kombinace s implantacemi umělých náhrad MCP kloubů bývá v rozvinutých případech nezbytná.
The ulnar deviation of the fingers is a part of a developed collapse deformity of the wrist and hand. The central pillar disorder of the hand begins with ulnar translocation of the carp in the frontal plane. According to Shapiro's theory, the carpus and metacarpal landscape behave biomechanically as one unit and the ulnar deviation and radial inclination of the wrist is followed by the radial inclination of the metacarpus and the ulnar deviation of the fingers. In the area of MCP joints, there is a tendency to ulnarly dislocate the course of the extensor tendons of the 2nd to 5th finger due to the loosening of the ligament apparatus. Their slipping from the top of the MCP joint into the intermetacarpal spaces results in a limitation of their extension ability. Extensors in their new, pathological course become ulnar ductors of the fingers and further strengthen and fix ulnar deviation.Surgical interventions that lead to the capture of the ulnar carpus deviation prevent the collapse deformity and thus ulnar deviation of the fingers. The basic procedure comprises early synovectomy of the dorsal portion of the carpus and peritenosynovectomy of the extensor tendons followed by tendon transposition, synovectomy of the MCP joints together with interventions that repose the physiological course of the extensor tendons. Limited joint fusions in the proximal row of carpal bones are also used. Tonalization of radial collateral ligaments and transposition of insertions of ulnar interosseal and lumbrical muscles to the radial part of the proximal phalanx of the next finger is one of the most complicated surgical procedures in this region. Their combination with implantation of artificial MCP joint replacements is necessary in developed cases.
