“…We report a series of locked MCP of which the epidemiological characteristics are similar to those already reported, with the majority (70% in our series) of locked MCP concerning the index or the middle finger and a sex ratio around 50-50 (60% women in our series) [1,19]. [ ( ) T D $ F I G ] However, we realized that the locking may occur in flexion or in extension, a point that needs to be clarified since the commonly accepted definition of locked MCP is: ''a clinical entity characterized by a loss of extension with little or no loss of flexion, with no impairment of the IP joints motion'' [1].…”

“…Harvey [13] and many other authors [1,4,[14][15][16][17][18][19][20][21] tried to explain the mechanisms of such locks: congenital abnormalities [22,23]; exotosis of the metacarpal head [24]; entrapment of first dorsal interosseous [4]; palmar plate tear [1]; intra-articular loose body [17].…”

“…The sole treatment is surgery for the vast majority of authors [1,12,13,19,24] as the unique solution to treat the cause. Some rare authors have suggested that manual reduction can be attempt [25,26].…”

“…The clinical picture of the MCP joint is very similar despite the diverse etiologies [4][5][6][7][8][9][10][11]: the MCP joint is locked at approximately 30-50° flexion with impossibility of active or passive extension [12]. Although unusual, locking in extension may happen depending on the site of the impingement [1].…”

Background: Distal fingertip amputations with exposed bone is challenging for the surgeon to manage. In order to reconstruct a good sensate pulp with appropriate closure, various flaps are advocated in the literature. Of these, palmar advancement flap, first described by Moberg in 1964, comprises one of the most popular options. Methods: Thirteen patients (11 male, 3 female) with fingertip injuries were operated. Following the elevation of Moberg flap, proposed modifications were carried out. Joint mobility and pulp sensitivity were recorded as well and advancement scores were noted before and after the modification. These scores were assessed statistically. Results: No complications were noted and there was no need for additional surgery. Excellent joint mobility and pulp sensitivity were maintained. This modification showed a statistically significant improvement in the advancement (p<0.05). Conclusions: Moberg flap is a good option for the closure of fingertip defects. Some simple modifications, as described in here, can enhance the advancement while securing the entire advantages of the flap. IntroductionThe hand is a unique part in the body in and plays important and often irreplaceable functions. In the industrialized world, occupational hand injuries need to be healed as soon as possible. Meanwhile, several healing techniques with various options are being applied to hundreds of thousands of patients by experienced practitioners.Unlike other hand injuries, fingertip amputations need additional attention in order to establish a normal pulp sensibility and maximum range of motion, and like others to maintain the upmost level of hand functioning.In 1964, the volar advancement flap was first described by Moberg for the reconstruction of pulp defects of the thumb (1). This flap is a pedicled advancement flap proximally based on an intact skin pedicle including both neurovascular bundles. This technique establishes a successful neurosensation of the pulp with a limited advancement as well. However, a simple modification as described here, and never been reported elsewhere, can enhance additional advancement. Patients and MethodsThe study was performed with informed consents obtained from all participants.Technique Thirteen patients (11 males, 3 females) with fingertip injuries were operated under regional anaesthesia. Palmar advancement flap was raised over the parathenon (1) (Figure 1a). Both neurovascular bundles were included in the flap so that neurosensible coverage is accomplished (Figure 1b). To increase the Hand Microsurgery & ABSTRACT Objectives:The purpose of this article was to present two exemplary cases of the disorder known as locked metacarpophalangeal (MCP) joint of long fingers, to review the literature and to recommend the possible surgical approaches based on the involved anatomic structures. Patients and Results:We recently took care of two patients with locked MCP joint representing the two main etiologies of this disorder. After clinical and imaging investigations both patients we...

“…Trauma limited to the hand, inflammation, spasticity, central nervous system disease, prolonged spasm, and excessive immobilization can cause such muscle contracture [1,2,4,5,[7][8][9]12]. Metacarpophalangeal (MP) joint locking is known to be caused by muscular contracture or trauma, collateral ligament, or volar plate tethering on a prominent MP head or osteophyte, a torn palmar plate, metacarpal head fracture, a loose body, or abnormal sesamoids [10,11]. We report the very rare cause of MP joint snapping with intrinsic plus deformity, which finally became locked.…”
