Degenerative and traumatic ligament lesions of the carpometacarpal joints frequently occur at the thumb ray, whereas the carpometacarpal amphiarthrosis of other finger rays are rarely affected. The metacarpophalangeal and interphalangeal joints of the thumb and fingers are stabilized by bilaterally running collateral ligaments and palmar plates. At the base of the metacarpophalangeal joints, several ligaments of the extensor hoods guide the extensor tendons and coordinate the fine motoric skills of phalangeal flexing and extending...

RATIONALE: For localized type Volkmann's contracture, in which degeneration of the flexor digitorum profundus (FDP) muscle to one or two fingers and restriction of finger extension occur, dissection or excision of the affected muscle is usually recommended. However, these surgical procedures need relatively wide exposure of the muscle, because the FDP muscle is in the deep portion of the forearm. PATIENT CONCERNS: In this report, the case of a 35-year-old woman with localized type Volkmann's contracture is presented...

Due to a lack of appropriate image resolution, most ultrasound scanners are unable to sensitively discern the pulley tissues. To extensively investigate the properties of the A1 pulley system and the surrounding tissues for assessing trigger finger, a 30 MHz ultrasound system was implemented to perform in vitro experiments using the hypodermis, A1 pulley, and superficial digital flexor tendon (SDFT) dissected from cadavers. Ultrasound signals were acquired from both the transverse and sagittal planes of each tissue sample...

Human hand is involved in variety of precision work which requires a combined effort of forearm muscles as well as intrinsic muscles of hand. Lumbricals along with interossei muscles connect the tendons of flexor and extensor muscles and thus play a key role in the characteristic movements of human hands. Lumbricals originate from long flexor tendon and is inserted into dorsal digital expansion. Any variation in the attachment of these muscles can lead to deviation from the normal actions of the fingers and their proximal extension into carpal tunnel and might lead to carpal tunnel syndrome...

#5
Andrés A Maldonado, Santiago Romero-Brufau, Michelle F Kircher, Robert J Spinner, Allen T Bishop, Alexander Y Shin
BACKGROUND: Reconstruction after pan-plexus root avulsions often includes gracilis free functioning muscle transfer. For elbow flexion reconstruction, the free functioning muscle transfer distal tendon is inserted into the biceps tendon or more distally (i.e., flexor digitorum profundus/flexor pollicis longus tendons) for combined elbow and finger flexion; the theoretical drawback of the latter approach is weaker elbow flexion. The authors compared elbow flexion strength with a biceps tendon versus a flexor digitorum profundus/flexor pollicis longus tendon attachment to determine which insertion point resulted in better elbow flexion...

A spontaneous tendon rupture is a direct consequence of rheumatoid inflammation and can appear without any noticeable impact, often during sleep. The patient then presents with inability to flex or extend metacarpophalageal or interphalangeal joints. Multiple ruptures resulting in impaired function of several fingers can also occur and markedly limit the hand's grip strength. A tear may arise from either mechanical injury to the tendon along its course over bone or connective tissues, or by biochemical action of lysosomal enzymes, released during the inflammation process, on the connective tissue of the tendon...

BACKGROUND: The Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire is the most commonly applied patient-reported outcome measure used to assess disability and functioning in clinical research and practice for patients with injuries and diseases of the upper extremities. The objective of this study was to assess whether the DASH is a valid and reliable questionnaire to measure disability and functioning in patients with hand injuries and diseases using Rasch analysis. METHODS: We performed a psychometric study using data derived from two multicentre studies carried out to develop the International Classification of Functioning, Disability and Health (ICF) Core Sets for Hand Conditions...

Jacques X Zhang, Jason Gray, Donald H Lalonde, Nicholas Carr
The literature generally supports the safety of epinephrine injection in the digits, but recent case reports describe ischemic adverse events associated with the use of lidocaine and epinephrine in which phentolamine rescue was not performed. We present a case of finger necrosis and subsequent amputation in a patient after 1% lidocaine with 1:100,000 epinephrine was injected in the fat and flexor sheaths in the palm for a 3-finger trigger release. Phentolamine rescue was not performed. All surgeons who use epinephrine in the finger should be prepared to reverse vasoconstriction with phentolamine rescue if there is persistently inadequate perfusion of the fingertip...

To examine a common plantar tendinous plate for long flexors of the toe and fingers in human embryos, we observed sections of 10 embryos at 5-6 weeks (crown-rump length or CRL 15-21 mm). The heel or tuber of the calcaneus was underdeveloped in 3 embryos with CRL 15 mm and the talus appeared not to be piled up on the calcaneus but these two bones were arranged along the lateromedial axis. As reported in the hand, we demonstrated, in the deep side of tarsal bones, a common tendinous plate formed by a joining of the flexor halluces longus and flexor digitorum longus tendons...

BACKGROUND: The purpose of the present study was to compare the operative time for graft preparation using different techniques for graft suturing. MATERIAL AND METHODS: Flexor profundus tendons were harvested from fresh pig hind-leg trotters. Three different suture techniques were investigated: the Krackow stitch (K), the Whipstitch (W), and the Modified Finger-Trap suture (MFT). Tendons were sutured starting at 10 mm from the distal free end of the tendon. The suture configurations of the Krackow stitch and Whipstitch were completed with five suture throws...

C7-T1 brachial plexus palsies result in a loss of finger motion and hand function. The authors have observed that finger flexion motion can be recovered after a brachialis motor branch transfer. However, finger flexion strength after this procedure merely corresponds to Medical Research Council Grades M2-M3, lowering the grip strength and practical value of the reconstructed hand. Therefore, they used 2 donor nerves and accomplished double nerve transfers for stronger finger flexion. In a patient with a C7-T1 brachial plexus injury, they transferred the pronator teres branch to the anterior interosseous nerve and the brachialis motor branch to the flexor digitorum superficialis branch for reinnervation of full finger flexors...

INTRODUCTION: Stenosing tenosynovitis that is characterized by the inability to flex the digit smoothly, usually leads to prolonged rehabilitation or surgery. STUDY DESIGN: This case series is a retrospective cohort study. PURPOSE: The aim of this case series was to evaluate the effectiveness of radial extracorporeal shockwave therapy (rESWT) for the treatment of stenosing tenosynovitis of the digital flexor tendon (trigger digit). METHODS: A retrospective analysis of 44 patients (49 fingers) treated with an individually adapted rESWT protocol was conducted...

OBJECTIVE: Anatomic volar rim locking plates are designed with the aim of treating intraarticular distal radius fractures. When used to treat comminuted distal radius fractures, these plates can damage the flexor tendons. In this study, we sought to determine the radiological and functional results and rate of complications of these plates. METHODS: We retrospectively reviewed the records of 36 patients (28 males, 8 females; mean age: 46.4 years) with AO/OTA Type C2-C3 distal radius fractures treated with anatomic volar rim distal radius plates between January 2011 and December 2014...

Secondary surgical procedures can improve the function of revascularised and replanted digits. We describe the case of a patient who underwent multidigit revascularisation and replantation following a saw injury at flexor tendon Zone II. To achieve maximal functional improvement after finger revascularisation, we performed secondary surgical procedures in an order that was determined by following a reconstructive decision procedure that covered late revascularisation, nerve reconstruction, pedicled vascularised joint transfer, staged flexor tendon reconstruction and skin revision...

Chondroma is a relatively rare, but well-reported benign neoplasm. This lesion normally occurs attached to bone; however, they may be rarely found without association to bone and embedded in soft tissue. The authors describe the case of a 76-year-old man in whom flexor tendon triggering was associated with an extraskeletal chondroma between the annular ligament and the flexor tendon.

BACKGROUND: Ultrasonography can be used in early Rheumatoid Arthritis to determine and to follow parameters of joint inflammation, such as effusion, synovitis, and marginal erosion that can be radiologically occult. We therefore planned a study to investigate whether Ultrasonography could provide information on signs of inflammation and destruction in Rheumatoid Arthritis affected finger joints that was not available with Radiography and compared it to the information provided by Magnetic resonance imaging...

Digital amputations are frequent injuries, the majority of them are caused by workplace accidents. Microsurgical techniques are an alternative option to repair these amputations. This study aims to report our experience in digital replantation through the examination of 18 cases. We conducted a retrospective study of 14 patients with total or subtotal fingers amputation between June 2013 and January 2015. All unidigital and multidigital replantations downstream of the distal insertion of superficial flexor tendon as well as all digital replantations upstream of the distal insertion of superficial flexor tendon were included in our study...

OBJECTIVE: Hamate hook fractures are rare injuries, comprising 2% to 4% of all carpal fractures. Climbing athletes seem to be affected more frequently than others, as they strain the passive and active anatomical structures of their hands and fingers to maximum capacity during training or competing. This stress is transmitted to the hook of the hamate by tightened flexor tendons, which creates high contact pressure to the ulnar margin of the carpal tunnel. Injuries of the hamate hook, caused by contact pressure of the anatomical structures, are rare and occur nearly exclusively during climbing...
