PURPOSE: The purpose of this study was to analyze the effects of different intervals between stitch throws on tendon graft fixation with the Krackow stitch. METHODS: Forty-four porcine flexor profundus tendons were randomly divided into four groups of 11 specimens each. The Krackow stitch with various stitch intervals (2.5, 5.0, 7.5, and 10.0 mm) were evaluated, and named the K-2.5, K-5.0, K-7.5, and K-10.0 groups, respectively. A braided nonabsorbable suture was used to complete each suture-tendon construct...

Jochem M Hoogendoorn
Fixation of the posterior fragment in trimalleolar fractures remains a matter of debate. Recent studies have shown that a persistent step-off in the tibiotalar joint is the most important factor in the development of osteoarthritis and therefore the functional outcome. The disadvantages of the regularly performed indirect reduction by ligamentotaxis or percutaneous reduction followed by percutaneous screw fixation of the posterior fragment in an anterior-to-posterior direction are that an anatomical reduction is more difficult to achieve because of the interposition of soft tissue or loose osseous fragments, it is hard to assess reduction satisfactorily using an image intensifier, and fixation of small or comminuted fragments is technically difficult...

Ernst Trömner (1868-1930) was a German neurologist and psychiatrist at the St. Georg Hospital in Hamburg. As clinician and researcher, he contributed to our understanding of various fields within neurology including language and speech disorders, hypnosis and suggestion, sleep physiology and diseases, leukemia with nervous system involvement, gait disorders, metabolic myelopathy, Parkinson's disease, organic psychosis, and schizophrenia. However, his main interest was muscle reflexes. De facto, Trömner described a variant of the Achilles tendon reflex, a modification of the Oppenheim's and Babinski's reflexes, "rediscovered" the corneomandibular reflex and described the joint reflexes of the lower extremities as well as a muscle stretch reflex of the diaphragm...

Distal radius fractures represent the most frequent bone fractures in humans. Although the treatment was dominated for decades by conservative measures or closed surgical procedures, such as percutaneous wire osteosynthesis, a paradigm shift was instigated by the introduction and rapid dissemination of volar locking plate osteosynthesis (VLP). The novel procedure was soon proclaimed to be the gold standard and applied for practically all forms of fractures of the distal radius. In addition to clinical mishaps, e...

Background: Musculoskeletal and finite element modelling are often used to predict joint loading and bone strength within the human hand, but there is a lack of in vitro evidence of the force and strain experienced by hand bones. Methods: This study presents a novel experimental setup that allows the positioning of a cadaveric digit in a variety of postures with the measurement of force and strain experienced by the third metacarpal. The setup allows for the measurement of fingertip force as well...

REVIEW

There has been an increase in thrower-specific elbow injuries in recent years. High valgus stresses during the late cocking and acceleration phases of throwing need to be compensated by the flexor pronator muscles as these can exceed the tensile strength of the medial collateral ligament complex. Prevention of injuries is the priority, with a focus on strengthening, reducing throwing frequency, decreasing force, and promoting a technique. The spectrum of thrower injuries ranges from a simple sprain to complete failure of the valgus stabilizing factors...

PURPOSE: The studies comparing the fixation methods being used for the ruptured distal biceps brachii tendon reinsertion show similar outcomes of cortical button and suture anchors usage, however, longer follow-up studies remain necessary. The goal of this study was to compare the clinical and functional three-year outcomes of the cortical button in contrast to the suture anchor fixation. METHODS: A retrospective cohort study comprised of 28 males on average 3 years after surgical reinsertion of the distal biceps brachii tendon with the use of a cortical button (Group I, n = 11) or a suture anchor (Group II, n = 17)...

The aim of this study was to delineate the pattern of sympathetic innervation in the suprasesamoidean region of the deep digital flexor tendon (DDFT) in horses with tendinopathy by immunohistochemical labelling for tyrosine hydroxylase (TH) and α-1 adrenergic receptor (α1-AR). Twelve forelimbs were obtained from 10 horses with DDFT tendinopathy and six feet obtained from six horses were used as healthy controls. Post-mortem radiographic, ultrasonographic and gross examinations were performed on the suprasesamoidean area of the DDFT to assess the presence of tendinopathy...

RATIONALE: Spontaneous flexor pollicis longus (FPL) tendon rupture is rarely reported. Although there are several studies investigating spontaneous FPL tendon rupture, the exact etiology of spontaneous rupture is unclear. Here, we present a case of unusual spontaneous FPL tendon rupture due to tendolipomatosis. PATIENT CONCERNS: A 64-year-old right-handed retired male teacher was referred to our clinic with an inability to flex the interphalangeal joint of his left thumb...

Introduction: The quadriga phenomenon results from excessive shortening of the flexor digitorum profundus (FDP) tendon to the middle, ring, or small finger. Methods: Five cadaveric specimens were used to create a model for quadriga. The FDP tendons to the middle, ring, and small fingers were shortened in 5-mm increments, and the tip-to-palm (TTP) distance of adjacent fingers was recorded. Results: Shortening of the middle finger FDP by 10 mm resulted in an average TTP distance of 6 mm in the ring finger and 5 mm in the small finger...

Peng-Bo Luo, Chang-Qing Zhang
Carpal tunnel syndrome (CTS) is well recognized as the most common type of peripheral neuropathy. A rare cause of CTS is tophaceous gout. Tophi deposits can accumulate in various structures including the flexor tendons, tendon sheaths, the carpal tunnel floor, transverse carpal ligament, and even the median nerve, causing various symptoms such as pain, numbness, and weakness. Tophi forming in the carpal canal can compress the median nerve, leading to CTS. Here, we describe a 25-year-old male with a family history of tophaceous gout who presented with typical CTS symptoms...

BACKGROUND: This study evaluated the functional outcomes of bipolar pedicled pectoralis major (PM) transfer to restore elbow flexion. METHODS: We retrospectively reviewed 29 transfers in 28 patients with a mean age of 31.2 years (range, 5-65 years). The loss of elbow flexion was due to brachial plexus palsy in 24 patients, elbow flexors necrosis in 4, and poliomyelitis in 1. The entire PM muscle was mobilized and fixed proximally to the coracoid process. Intraoperative positioning and postoperative immobilization of the shoulder and the elbow flexed at 60° and 120°, respectively, allowed direct distal fixation of the muscle to the biceps brachii tendon...

BACKGROUND: Osteomyelitis of the wrist is rare but destructive. Subsequent bone defects often require vascularized bone for successful healing. Recent literature has pointed to the successful use of the medial femoral condylar (MFC) flap for difficult non-unions, yet it has not been specifically described for wrist fusion. We present our experience with this technique for limited and complete wrist arthrodesis. PATIENTS AND METHODS: We reviewed 4 cases of radiocarpal bone loss from osteomyelitis...

PURPOSE: Grayson ligament has been described as a common pathway for digital contracture in Dupuytren disease. Its anatomical descriptions in the literature are, however, inconsistent. METHODS: We have performed a microsurgical dissection study in 20 fresh-frozen and thawed digits to revisit the anatomy of Grayson ligaments. We also performed dissections in Thiel-preserved hands to be able to study the changes in tension of the ligaments during flexion and extension of the finger...
