Ligamentotaxis is now a well-established treatment method for proximal interphalangeal (PIP) joint fractures. Despite satisfactory results, the technique is considered complex and the devices cumbersome. The aim of this study was to evaluate a miniaturized dynamic external fixator (Ligamentotaxor(®)) for the management of these fractures. Eighty-six patients with 88 fractures of the PIP joint were treated at 10 European hand surgery centers. The device was applied within eight days of the injury and was removed 40-45 days after the injury...

Anterior submuscular transposition of the ulnar nerve described by Dellon can solve the dynamic component of cubital tunnel syndrome at the elbow. We carried out a retrospective, single-surgeon study. The McGowan scale as modified by Goldberg (MG) was used preoperatively and at the final assessment; the QuickDASH was completed at the final assessment. The cohort comprised of 82 patients (38 females, 44 males) with a mean age of 61.2 years (37-92). The preoperative MG grade was: stage I (52%), IIA (28%), IIB (16%), III (4%)...

UNLABELLED: To evaluate objective and subjective outcomes after minimally invasive volar locked plate fixation of distal radius fractures with metaphyseal extension, we retrospectively evaluated 13 patients with unstable distal radius fractures with metaphyseal extension, treated by minimally invasive volar locked plating. Patients' average age was 41 years. Two volar incisions, 2 to 3cm long, were made; indirect reduction was performed and a volar locked T-plate was placed submuscularly under fluoroscopy guidance...

This case report features a patient with chronic bilateral compartment syndrome of the thenar muscles, which had appeared spontaneously 8 years earlier. The condition was progressive and symptoms recently had become worse. Pressure measurements were performed three times to establish the diagnosis: before, immediately after and 10 minutes after hand exertion. Pain relief was achieved by performing a fasciotomy of the right thenar compartment.

We report an unusual case of avulsion of the flexor digitorum profundus tendon of the ring finger at its insertion, in combination with a pathological fracture of the distal phalanx due to enchondroma. The bone lesion was curetted and grafted using autogenous bone. The FDP tendon was reattached to the distal phalanx using the pullout technique. We describe this case in detail and discuss the surgical management through a review of literature.

Several treatment options exist to surgically treat end-stage trapeziometacarpal osteoarthritis. Trapeziectomy is recognized as leading to a mostly acceptable functional outcome. Although rarely encountered, persisting failure of the trapeziectomy is difficult to address. We present a case where several procedures were subsequently performed to treat a failed trapeziectomy condition. First, a trapeziometacarpal prosthesis (Arpe(®), Biomet(®)) was inserted with the two components reversed: the cup in the first metacarpal and the stem in the scaphoid...

The goal of this study was to assess the results of treatment of mucous cysts by subcutaneous excision and osteophyte resection without an associated skin procedure. From 1993 to 2013, 81 mucous cysts were operated on. In 27 cases, a nail deformity was present. Obvious osteoarthritis was present in 84% of cases. Among them, 67 patients (68 cysts) were subsequently assessed through a phone questionnaire after a mean follow-up of 6.6 years. Patients who reported a recurrence or suspected one were reassessed in consultation...

Chronic finger extensor apparatus injuries are the result of the initial acute treatment having failed or being flawed. Because of their chronic nature, these injuries present various amounts of tendon retraction, tendon callus lengthening, peritendinous scar adhesions, static and dynamic imbalances with the flexor apparatus and intrinsic muscles, and joint contractures. This article will review the anatomy of the extensor mechanism and then will outline by location, the various clinical pictures that are secondary to chronic tendon injury...

The thumb is frequently impaired in rheumatoid arthritis. This leads to major disability in affected patients. Through a clinical case, we describe a reconstructive strategy for a three-joint adduction thumb deformity that caused instability of the interphalangeal and metacarpophalangeal joints, without cartilaginous lesion. Ulnar collateral ligament destruction was treated by a bone-ligament-bone graft at the interphalangeal joint and by a Littler ligamentoplasty at the metacarpophalangeal joint. The trapeziometacarpal lesion was treated by trapeziectomy in combination with suspension ligamentoplasty...

Paralysis of the suprascapular nerve, in partial injuries of the brachial plexus, most often warrants a nerve transfer. Transfer of the spinal accessory nerve to the suprascapular nerve is performed most often. We propose to directly transfer the nerve of the rhomboid muscles (branch of the dorsal scapular nerve) to the suprascapular nerve in the supraspinatus fossa. This anatomical study included 10 shoulders. Dissection of the suprascapular nerve and the branch of dorsal scapular nerve to rhomboid muscles (rhomboid nerve) was performed through a posterior approach...

The mechanical properties of nerve guide tubes must be taken into consideration when they are being developed. We previously reported the feasibility of using 50:50 tubes in a canine 40mm peroneal nerve defect model, where 50:50 represents the proportion of poly(L-lactic) acid (PLLA) and polyglycolic acid (PGA). The aim of the current study was to show that 50:50 tubes have suitable mechanical properties for repairing long nerve defects. Four types of nerve guide tubes made with PLLA to PGA fiber ratios of 100:0 (i...

Among the various techniques proposed to protect the median nerve from scarring and to provide it with a vascular supply, the synovial flap represents a simple and effective method. The flap is taken from the flexor tendons sheath and results in a thin and richly vascularized tissue that will act as a barrier to scarring and provide neovascularization to improve nerve regeneration and gliding. The aim of this study was to evaluate the arterial vascularization of this flap to assess its reliability. An anatomic study was carried out on 24 fresh upper limbs infused with colored and radiopaque solutions before or after flap elevation...

Patients suffering from carpal tunnel syndrome (CTS) actively search for medical information on the Internet. The World Wide Web represents the main source of patient information. The aim of this study was to systematically assess the quality of patient information about CTS in the Internet. A qualitative and quantitative assessment of websites was performed with the modified Ensuring Quality Information for Patients (EQIP) tool that contains 36 standardized items. Five hundred websites with information on CTS treatment options were identified through Google, Bing, Yahoo, Ask...

Flexor tendon tenolysis consists of the surgical release of adhesions formed around tendons that persist despite splinting and appropriate rehabilitation. The aim of this study was to evaluate the increase in active range of motion following flexor tenolysis in zone II and to document the ensuing complications. Sixty patients (75 fingers) underwent zone II flexor tenolysis following flexor tendon injury, with or without dorsal tenolysis or PIP arthrolysis. Tenolysis cases following tendon graft or replantation were excluded...

UNLABELLED: The main complications in distal interphalangeal (DIP) fusion are non-union and hardware-related symptoms. The primary aim of this study was to show that joint preparation for DIP fusion is not necessary in cases of stage IV chondropathy. The secondary aim was to show that use of buried compression screws decreases the complication rate. This continuous retrospective study included two groups of DIP percutaneous arthrodesis procedures carried out with 1.8mm break-away compression screws: group 1 underwent joint preparation through a dorsal approach and group 2 underwent a percutaneous procedure without joint preparation...

Online learning (or eLearning) is in constant evolution in medicine. An analytical survey of the websites of eight academic societies and medical schools was carried out. These sites were evaluated against parameters that define the quality of an eLearning website, as well as the shareable content object reference model (SCORM) technical standards. All studied platforms were maintained by a webmaster and regularly updated. Only two platforms had teleconference opportunities, five had courses in PDF format, and four allowed online testing...

The goal of this study was to compare the advantages and disadvantages of horizontal versus vertical traction by reviewing a small series of metacarpophalangeal (MCP) joint arthroscopy in the fingers other than the thumb. Our series included eight patients operated with traction placed along the axis of the operated finger. In four cases, traction was applied horizontally and in the other four, it was applied vertically. Arthroscopy was performed using dorsomedial and dorsoradial portals. The fluoroscopy unit was placed either vertically or horizontally as required...

The TASER(®) is a self-defense weapon whose use has now become commonplace among law enforcement agencies. Electronic control weapons were first used in the USA in the 1990s and then adopted in Europe and France. We report a case of an 18-year-old male who presented a penetrating lesion of the middle phalanx of the left index finger. To the best of our knowledge, this is the first complex finger injury due to the TASER(®). It highlights the potential major risks to finger vitality and function with use of this electrical weapon...
