Article
The medial femur condyle (MFC) cortico-periosteal flap is a popular flap for bone reconstruction. The use of a chimeric version of this flap with a skin island has been described, but anatomical arterial variation can occur that prevent its harvest. Furthermore, the donor area of the skin paddle has been debated as poor because of the scarring in a...

Article
Full-text available
Background and Objectives: Retrograde free venous flaps represent a separate entity among free venous flaps: their physiology is still unclear, but they provide an immediate visible refill after reconnection, with a similar behaviour to conventional flaps. Therefore, the dimensions and the indications of these flaps can be extended beyond what was...
Article
Zusammenfassung Fingergelenksarthroplastiken mit Silikonimplantaten zur Behandlung einer degenerativen, rheumatischen oder posttraumatischen Gelenksdestruktion werden seit Jahren mit gutem Erfolg durchgeführt. Bei akut schwer traumatisierten Händen erfolgt der Einsatz von Silikonimplantaten selten. Wir berichten über 5 konsekutive Patienten, bei de...
Article
Zusammenfassung Seit Beginn erfolgreicher mikrochirurgischer Fingerreplantationen Anfang der 60er Jahre des letzten Jahrhunderts zeigt sich eine Evolution in den Techniken zur Wiederherstellung der Durchblutung der amputierten Finger. Initial wurden bei den ersten Fingerreplantationen End-zu-End-Anastomosen der Arterien und Venen durchgeführt. Spät...
Article
Intramedullary screw (IMS) fixation is increasingly used as an alternative treatment option in metacarpal and phalangeal fractures of the hand. However, this technique is currently the subject of controversy among hand surgeons. The aim of this systematic review was to gain insight on radiological, functional and patient-rated outcomes reported in...
Article
Degenerative changes of the distal interphalangeal (DIP) joints can be painful, disabling, and disfiguring. Swanson spacers can be used for DIP arthroplasty. The standard approach for Swanson spacer implantation at the DIP joint involves transecting the extensor tendon close to its insertion, which necessitates a 6-week period of postoperative immo...
Article
Arthroplasty of the distal radioulnar joint (DRUJ) using a semiconstrained DRUJ implant yields good outcomes according to the literature. The aim of this study was to investigate the subjective, clinical and radiographic outcomes with a special focus on complications in nine patients with a mean follow-up of 6 years and to compare them with our pre...
Article
Background: The aim of this study was to evaluate the effectiveness and safety of free corticoperiosteal medial femoral condyle (MFC) flap for ankle, hindfoot and midfoot reconstruction in patients with recalcitrant nonunion. Methods: Patients who underwent ankle and foot reconstruction using the MFC flap at our clinic were recruited for assessm...
Article
Introduction There is growing evidence of the superior ability of muscular tissue to clear bacterial bone infection. Unfortunately, in the hand, there are almost no small local muscular flaps, and muscular transfers to the hand are mainly microsurgical free transfers. In this report, we present the results of the use of a chimeric posterior interos...
Article
We aimed to examine if joint procedures in hands and wrists of patients with scleroderma could be performed without major morbidity and conducted a systematic review of the literature to assess this hypothesis. Studies were identified in four different databases; soft tissue procedures in scleroderma patients were excluded, and Preferred Reporting...
Article
Metacarpal fractures constitute 7.8% of the upper extremity fractures. The common treatments remain nonsurgical procedure, but high-demanding patients or unstable fractures require fixation with Kirschner wire (K-wires), plate, and screws. However, these approaches may cause scarring and adhesion with poor functional results. From 2014 to 2015, the...
Article
We report sonographic findings with clinical outcomes after zone 2 flexor digitorum profundus tendon repairs in ten fingers. The tendons underwent a six-strand M-Tang core repair, no circumferential suture, and partial or complete division of the pulleys. Over 12 months after surgery and using ultrasound, we found no gapping at the repair site duri...
Article
We analyzed the results of 20 unstable metacarpal fractures in 15 patients treated with a cannulated compression screw and no immobilization. All fractures healed within 6 weeks. One patient with multiple fractures and a flexion deficit required arthrolysis of two metacarpophalangeal joints. Another patient had an extension lag. There were no other...
Article
We report outcomes in 29 patients with flexor tendon repairs in 32 digits (five thumbs and 27 fingers) with our modified protocols. We repaired the lacerated flexor digitorum profundus tendons with core suture repairs using the 6-strand M-Tang method and without circumferential sutures. We divided the pulleys as much as needed to allow excursion of...
Article
The purpose of this study was to methodically illustrate and highlight the crucial steps of stromal vascular fraction (SVF)-enriched fat grafting as a novel treatment of symptomatic end-neuromata of peripheral sensory nerves, and in this study, specifically of the superficial branch of the radial nerve (SBRN). Despite a multitude of existing treatm...
Article
Common hand problems are treated differently in different countries. This article attempts to bring together the views of surgeons from different countries on some of the most common hand problems that hand surgeons encounter in daily practice. In practice, the correct treatment of these problems may be the most important and influential to patient...
Article
The protocol for primary flexor tendon repair in zones 1 and 2 of the hand is changing. This article discusses recent changes. Immediate repair within 48 hours is performed whenever possible. A 6-strand core suture is performed using the M modification of Tang's technique. The pulleys are divided to allow free excursion of the repaired tendon withi...

In this report a case of closed mallet thumb injury is described, which was diagnosed clinically and indication for surgical treatment was confirmed with ultrasound examination. The EPL-tendon was successfully reconstructed with an excellent result. We propose a mandatory ultrasound examination of all closed mallet thumb injuries.
Article
We present the results of a prospective study of 31 thumbs in 30 patients affected by primary osteoarthritis at the thumb carpometacarpal (CMC1) joint who were treated with denervation of the involved joint. For every operated hand, the Kapandji score, key-pinch strength, grip strength and pain on a visual analogue scale were evaluated preoperative...
Article
Injuries to the extremities with severe soft-tissue damage reveal to be challenging for both trauma and reconstructive surgeons. An effi cient interdisciplinary orthoplastic management is critical to rapidly defi ne an appropriate treatment strategy. The aim is twofold: Early defi nitive fracture stabilization and soft-tissue repair (fi x and fl ap...
Article
Introduction: None of the existing treatments in the management of painful end-neuromas of the superficial branch of the radial nerve (SBRN) has been proven superior due to high levels of pain relapse. Fat grafts enriched with the stromal vascular fraction (SVF) could act as a mechanic barrier with biological effects decreasing the resorption rate...
Article
Fifteen consecutive patients with severely comminuted Rolando fractures were treated by closed reduction and fixation with a modified Suzuki frame without rubber bands, followed by immediate mobilization. All the fractures healed within 5 weeks. At 3 months, no rotational deformity was observed. The Kapandji score was equal that of the contralatera...
Article
Skin coverage in hand reconstruction is a challenging and vast chapter in hand surgery; covering every aspect of it in a report is simply not feasible. Therefore, this report focuses on a few specific topics. The coverage of anatomical regions like the fingertips is common ground for hand surgeons worldwide, but in the last 10 years, various refine...

Full-text available
A severely painful, dysfunctional, or destroyed distal radio-ulnar joint (DRUJ) can be reconstructed by fusion, interposition of soft tissue, or by arthroplasty using prostheses. The objective of this study was to review the literature on implants and evaluate their effectiveness in terms of pain relief, range of motion and longevity. A search was...
Article
Full-text available
Range of motion and stability are important outcome parameters to assess function of the distal radioulnar joint (DRUJ), in particular pronation, supination, and weight-lifting capacity. The DRUJ semiconstrained implant developed by Scheker et al is intended to reproduce all the functions of the triangular fibrocartilage complex and the DRUJ. The a...

Unlabelled: We present the results of 26 patients with 31 consecutive displaced or unstable extra-articular fractures of the base and shaft of the proximal and middle phalanges of the digits of the hand, treated over a period of 12 months with an intramedullary headless compression screw and early mobilization with no splinting. All fractures heal...
Article
Background: As the sophistication of functional reconstruction procedures continues to increase, so does the need for valid, precise, and reliable instruments to assess their clinical results. The authors compare two tests for spatial resolution and two for cutaneous pressure threshold in an adult patient cohort having undergone microsurgical digi...
Article
Background: Population ageing strongly affects the demographic development of industrialized countries. While microsurgical procedures were initially believed to be only feasible in patients of younger age because of the duration of the surgical procedure and the higher risk of vascular insufficiency due to age-related comorbidities, it has become...
Article
Das Extremitätentrauma mit Weichteilschaden ist eine Herausforderung für die behandelnden Chirurgen. Für das Outcome entscheidend ist ein effizienter interdisziplinärer Behandlungsansatz durch Unfallchirurgen/Orthopäden und Plastische Chirurgen, die so früh wie möglich eine gemeinsame Strategie festlegen. Das Ziel dieses orthoplastischen Vorgehens...
Article
Digital replantation is a well-established and increasingly common procedure in specialized hand surgery units worldwide. Replantation after complex trauma is often challenging due to severely injured, small-diameter vessels, especially at the distal level. Digit salvage by arteriovenous anastomosis has been inadequately described in the literature...
Article
Reconstruction of the distal phalanx bone in cases with painful nonunion is a rare and challenging problem. To restore anatomy and to provide a good cover for the bone graft, an intact nailbed is often required due to the proximity of these 2 structures. We present 3 cases of distal phalanx reconstruction performed with a free corticocancellous bon...
Article
Peripheral neuromas can result in an unbearable neuropathic pain and functional impairment. Their treatment is still challenging, and their optimal management is to be defined. Experimental research still plays a major role, but - although numerous neuroma models have been proposed on different animals - there is still no single model recognised as...
Article
Purpose Although the literature is encouraging with regard to the survival rate of arterialized free venous flaps, previously reported difficulty in healing owing to early venous congestion and subsequent epidermolysis continues to prevent their widespread application. We report 14 arterialized free venous flaps for primary reconstruction of the ha...
Article
As primary repair of divided flexor tendons becomes more common, secondary tendon surgery becomes largely that of the complications of primary repair, namely ruptured and adherent repairs. These occur with an incidence of each in most reported series world-wide of around 5%, with these problems having changed little in the last two decades, despite...
Article
This article presents a technique for facilitating use of pinch between the ring and little fingers for use in rare cases of congenital absence, or severe hypoplasia, of the thumb in which pollicization of the index finger is impossible, or not advised because the child is already pinching by scissor action between the ring and little fingers. The...
Article
Repair of the divided flexor tendon to achieve normal, or near normal, function is an unsolved problem, with each result still uncertain. The authors believe the way forward in primary flexor tendon surgery clinically is by use of strengthened but simpler sutures, appropriate venting of the pulley system, and maintaining early rehabilitation. Howev...
Article
We recently reported a small study at the Federation of European Societies for Surgery of the hand, which was entitled 'What is secondary flexor tendon surgery'? This study concluded that 'secondary flexor tendon surgery' was a generic name encompassing a multitude of pathologies. Between 10% and 15% of cases exhibited pathology of the skin and sub...
Article
Full-text available
This review describes the biological problems faced by those managing primary flexor tendon injuries and explains why these problems still thwart attempts to achieve normal, or near normal, function after this injury, despite a century of surgical effort. It considers the historical background of the early 20(th) century attempts to improve the res...

Full-text available
There are different ways to treat peripheral nerve injuries with concomitant defects in the lower extremity. One option is a direct nerve suture followed by immobilization of the knee in flexion as it is described for gunshot wounds that lead to lesions of the sciatic nerve and its terminal branches as well as isolated nerve lesions. We used this t...
Article
The aims of this anatomical study were to identify any extrinsic blood supply to the median nerve in the distal forearm and to measure the tension required to approximate the severed nerve after and before dissecting it while maintaining its extrinsic blood supply. We injected the arterial system of 15 lightly embalmed forearms with red latex to de...

SUMMARY Purpose: The treatment options for mallet fractures of the distal phalanx range from splinting, to surgical fixation using percutaneous pins, pull-out wires, microscrews or interosseous wires. Drawbacks of most of the surgical techni- ques are open incision and long rehabilitation periods. While conservative treatment with splints is succes...
Article
SUMMARY Purpose: The occasional occurrence, in post-operative follow-ups, of proximal interphalangeal joint flexion stiff- ness in the long digits leaded us to define a post-operative rehabilitation protocol based on applying an extension dynamic night splint in addition to stretching, gliding and anti-edema exercises. The aim of this study was to...
