Aims. The paediatric trigger thumb is a distinct clinical entity with unique anatomical abnormalities. The aim of this study was to present the long-term outcomes of A1 pulley release in idiopathic paediatric trigger thumbs based on established patient-reported outcome measures. Methods. This study was a cross-sectional, questionnaire-based study conducted at a tertiary care orthopaedic centre. All cases of idiopathic paediatric trigger thumbs which underwent A1 pulley release between 2004 and 2011 and had a minimum follow-up period of ten years were included in the study. The abbreviated version of the Disabilities of Arm, Shoulder and Hand questionnaire (QuickDASH) was administered as an online survey, and ipsi- and contralateral thumb motion was assessed. Results. A total of 67 patients completed the survey, of whom 63 (94%) had full
Patients suffering from finger joint pain or dysfunction due to arthritis and traumatic injury may require arthroplasty and joint replacement. Single-part silicone-based implants remain the material of choice and most widely used option, although reports on their long-term clinical performance are variable. For trauma indications, patients have a high expectation of functionality necessitating the use of materials with high wear resistance and mechanical performance. A new proximal inter phalangeal (PIP) joint designed by Zrinski AG (Wurmlingen, Germany), comprising a self-mating carbon fibre reinforced polyetheretherketone (CFR-PEEK) coupling, may provide a suitable alternative. Here we describe the wear performance of the CFR-PEEK components in a PIP joint wear simulator and subsequent characterisation of the wear particles. Four proximal and distal PIP components were milled (Zrinski AG) from CFR-PEEK (Invibio Ltd, UK) and subjected to wear testing (Endo Lab ® GmbH, Germany). The test was conducted at 37°C over 5 million cycles in 25% bovine serum (refreshed every 0.5 million cycles). The load was a static force of 63N applied at a frequency of 1Hz with a flexion/extension angle of ±40°. Wear rate was determined by mass loss from each component. Pooled serum samples from the wear simulator were subjected to protein digest and the remaining particulate debris isolated by serial filtration through 10μm, 1μm and 0.1μm filters. Particle size and morphology was subsequently determined by scanning electron microscopy (SEM) (Continuum Blue, UK).Introduction

Normal digital flexion relies on flexor tendon pulleys to transmit linear muscular force to angular digital motion. Despite the critical role these pulleys play, there is a growing trend among surgeons to partially sacrifice or “vent” them during flexor tendon repair to improve surgical exposure. Although this new practice is reported to improve outcomes after flexor tendon repair, there is concern for the long-term effects of bowstringing, reduced finger range of motion (ROM) and altered tendon biomechanics. The objective of this study was to examine the effects of the application of a thermoplastic ring, acting as an “external” pulley, on flexor tendon biomechanics and finger ROM. We hypothesized that the application of an external thermoplastic ring would produce a centripetal force over the tendon to reduce bowstringing, improve finger ROM, and restore tendon loads following pulley venting. Twelve digits comprised of the index, long, and ring fingers from four cadaveric specimens were tested using a novel in-vitro active finger motion simulator. Servo-motors were used to generate motion. Loads induced by flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP), and joint range of motion were measured with each sequential sectioning of the A2, A3, and A4 flexor pulley, in comparison to a native healthy finger condition. At each finger condition, A2 and A4 external thermoplastic pulley rings were applied over the proximal phalanx and middle phalanx, respectively, to recreate A2 and A4 function. Results were recorded and analyzed using a one way repeated-measures ANOVA. Following venting of the A2, A3 and A4 pulley, proximal interphalangeal joint (PIPJ) ROM significantly decreased by 17.02 ± 8.42 degrees and distal

We treated 32 displaced mallet finger fractures by a two extension block Kirschner-wire technique. The clinical and radiological outcomes were evaluated at a mean follow-up of 49 months (25 to 84). The mean joint surface involvement was 38.4% (33% to 50%) and 18 patients (56%) had accompanying joint subluxation. All 32 fractures united with a mean time to union of 6.2 weeks (5.1 to 8.2). Congruent joint surfaces and anatomical reduction were seen in all cases. The mean flexion of the distal

The authors report their results of “extension-block Kirschner wire fixation” for the treatment of mallet finger fracture. This technique should be considered in presence of a large bone fragment involving more than the 30% of the articular surface, with or without palmar subluxation of the distal phalanx. A modification of the extension-block technique is described reducing the fragment to 0° extension of the distal
A retrospective analysis was done on 20 cases of interphalangeal joint fusion of the great toe utilizing longitudinal cortical screw fixation. The purpose of this study was to present a series of interphalangeal joint fusion great toe done in both paediatric and adult patients using 3.5mm cortical screws. Most of the patients had interphalangeal joint fusion along with Jones transfer and other associated procedures with a mean follow up period of 19 months. Arthrodesis was successfully achieved in all the patients. No one had pain at the
Purpose of the study: Duplication of the thumb is the most common congenital anomaly of the first ray. The characteristic feature of type IV is the diversity of the clinical forms and the presence of certain complex forms particularly difficult to treat (Hung IVD). We propose a new procedure for reconstruction of IVD type thumb duplication. Material and method: This new procedure was used for thumb reconstruction in two boys with type IVD thumb duplication. Mean age at surgery was 10 months. Surgical technique. The future incisions were traced with a central skin resection removing the most hypoplastic nail entirely (generally the radial nail). At the bone level, a longitudinal osteotomy of the proximal phalanges was made over the entire length to remove the central part and obtain a width for the first phalanx comparable to that of the contralateral thumb. An oblique osteotomy was cut in the base of the distal phalanx of the ulnar hemithumb with resection of a radial corner. The same type of osteotomy was performed at the base of the distal phalanx of the radial hemithumb, but with preservation of the radial corner and resection of the rest of the radial thumb. The proximal hemiphalanges were sutured as were the bases of the distal phalanges. This produced automatic realignment and stabilisation of the

We reviewed the results of reconstruction of 97 upper limbs in a consecutive series of 57 tetraplegic patients, treated from 1982 to 1990. Of these, 49 had functional and eight had cosmetic reconstructions. The principal functional objectives were to provide active elbow extension, hook grip, and key pinch. Elbow extension was provided in 34 limbs, using deltoid-to-triceps transfer. Hook grip was provided in 58 limbs, mostly using extensor carpi radialis longus to flexor pollicis longus transfer, and key pinch in 68, mostly using brachioradialis to flexor pollicis longus transfer. Many other procedures were employed. At an average follow-up of 37 months, 70% had good or excellent subjective results, and objective measurements of function compared favourably with other series. Revisions were required for 11 active transfers and three tenodeses, while complications included rupture of anastomoses and problems with thumb
1. The claw position of a finger with intrinsic paralysis is caused by the blocking effect of the transverse lamina on the long extensor. This starts as soon as the metacarpo-phalangeal joint is hyperextended, and increases with further hyperextension. Thus the long extensor loses its pull on the
The rheological properties of synovial fluid (SF) are largely attributed to the presence of high molecular weight hyaluronic acid (HA). In normal SF, HA has been shown to be an anti-inflammatory molecule able to increase the viscosity and promote endogenous production of HA. The aim of the present report was to investigate the possible effect of HA concentration in rheological properties (elastic modulus, G´ and viscous modulus, G´´) of osteoarthritic equine SF. For this purpose, SF from intercarpal, metacarpophalangeal and distal
Purpose: Two questions arise after metatarsophalangeal hallux arthrodesis: what are the 3D changes observed when walking on flat ground ? and is the arthrodesis compensation essentially at the talocrural or interphalangeal level ?. Material and methods: Our series included twelve patients (ten women and two men) mean age 60.7 years. Nine patients had unilateral arthrodesis and three bilateral arthrodesis. The optoelectronic exploration was conducted barefoot. The patients wore underclothes and 27 reflectors. A miniaturised reflector was placed on the distal end of each hallux. Three valid recordings were made. Results: General gait parameters and kinematic and kinetic values were unchanged (excepting nonsignificant maximal ankle dorsiflexion). On the arthrodesis side we observed: significant decline in propulsion force in the anteroposterior and vertical planes; significantly later heel lift-off; systematic anterior displacement of the ground reaction force of the metatarsophalangeal joint (not seen on the healthy side). Discussion: We propose a coherent explanation of these observations. The kinetics of balance movement under the head of the first metatarsal head is changed. When the foot is flat on the ground, as the ankle balance movement occurs, the weight of the body is transferred earlier and massively to the forefoot. While in the healthy foot this occurs under the metatarsophalangeal joint of the great toe, in arthrodesis patients body weight is transferred under the
Purpose of the study: Distal amputation of the long fingers with loss of dorsal or volar tissue may leave bone exposed requiring fingertip reconstruction to restore sensorial and tactile function. Several methods have been proposed for fingertip reconstruction. Among the methods the most widely used, thenar flaps predominate because of they are reliable and easy to perform but especially because of the very high-quality tissue function achieved. Material and methods: We report a series of 86 patients who presented an amputation of a long finger during a 4-year period (January 1998 to December 2002). A tenar flap was constructed within 24 of the operation. Mean patient age was 26 years; 80% of the accidents were occupational accidents; tissue loss was caused by sharp instruments in 72% of the cases; three-quarters of the cases involved the left non-dominant hand; the greatest damage was to the middle finger in 58% of cases. Loss of dorsal tissue was noted for 80% of the amputations. Trunk anesthesia was used for all patients to achieve cover with a thenar flap with a proximal pedicle in 80%. The flap was weaned from its blood supply at 18 days on average. Results: Outcome was assessed with three criteria at mean follow-up of one year. Subjectively, 80% of patients were satisfied with the operation. Permanent flexion of the distal
1. The range of variation in full extension at the interphalangeal and metacarpo-phalangeal joints of the thumbs of 133 male and 100 female Europeans, and of 31 male Indians and 30 male Africans, has been investigated. 2. There is considerable variation between individuals in the maximum extension of both joints of the right and left thumbs in all groups studied. 3. The distribution for each joint in both thumbs in all groups is fairly symmetrical. 4. There is a high correlation between the right and left thumbs for both joints in all groups. 5. The mean angle of extension at the right and left metacarpo-phalangeal joints in all groups is similar. Female Europeans, however, show a significantly greater mean angle than male Europeans. 6. The mean interphalangeal angle of extension in male Europeans is significantly greater than that in female Europeans and the mean in the Indian and African groups is significantly greater than in the male European group. 7. There is slight negative correlation between the metacarpo-phalangeal angle and interphalangeal angle in each thumb in the European groups. 8. Many subjects in all groups can increase extension at the metacarpo-phalangeal joint after flexing the carpo-metacarpal joint. Marked hyperextension (over 40°) is more frequent in the left than in the right thumb, in females than in males, and in male Indians than in male Europeans and Africans. 9. Maximum extension at the
Rheumatoid arthritis is a whole body, lifetime incurable disease. The problems engendered by the disease process itself are highly individual, given that each set of problems that a patient has, the assessment and planning of surgery is a crucial aspect of the appropriate management of patients with polyarthritis. The presence of deformity does not necessarily indicate a problem of function, but one has to accept that certain deformities cause more problems than others and I draw your attention to swan neck deformity being relatively function-impairing and Boutonnière deformities less so. There is always a balance between the risk of surgery and the benefits to be obtained. The assessment is functional, anatomical, radiological, psychological, medical, financial and, finally, surgical. The functional assessment is intended to identify the problems a patient has in the activities of daily living, the anatomical assessment identifies the structures damaged which need to be prepared or replaced, the x-rays define the bone loss and, therefore, determine the limits of bony surgery, the psychological aspect identifies the patient’s capacity and willingness to be involved in often quite complex therapy programmes over a significant period of time. The medical problems of vasculitis and active disease are less frequent now but are contra-indications to surgery in the acute phases. The financial aspects are often under-rated. The costs of maintaining someone with significant disabilities is really quite great and, therefore, although surgery may only give some small improvement in function, it often has quite a significant impact on the degree of care and help an individual needs. Finally, the surgical assessment is to identify which structures and in which order. In terms of planning, the surgical priorities, described by Nalebuff, are:. 1 Nerves 2 Flexor tendons 3 Wrist 4 Thumb 5 MCP joints 6 Extensors 7 PIP joints 8 Distal
Introduction and Objective. Zone 2 flexor tendon injuries are still one of the challenges for hand surgeons. It is not always possible to achieve perfect results in hand functions after these injuries. There is no consensus in the literature regarding the treatment of zone 2 flexor tendon injuries, tendon repair and surgical technique to be applied to the A2 pulley. The narrow fibro-osseous canal structure in zone 2 can cause adhesions and loss of motion due to the increase in tendon volume due to surgical repair. Different surgical techniques have been defined to prevent this situation. In our study, in the treatment of zone 2 flexor tendon injuries; Among the surgical techniques to be performed in addition to FDP tendon repair; We aimed to compare the biomechanical results of single FDS slip repair, A2 pulley release and two different pulley plasty methods (Kapandji and V-Y pulley plasty). Materials and Methods. In our study, 12 human upper extremity cadavers preserved with modified Larssen solution (MLS) and amputated at the mid ½ level of the arm were used. A total of 36 fingers (second, third and the fourth fingers were used for each cadaver) were divided into four groups and 9 fingers were used for each group. With the finger fully flexed, the FDS and FDP tendons were cut right in the middle of the A2 pulley and repaired with the cruciate four-strand technique. The surgical techniques described above were applied to the groups. Photographs of fingers with different loads (50 – 700 gr) were taken before and after the application. Proximal
We randomised 79 patients (84 hands, 90 fingers) with Dupuytren’s contracture of the proximal interphalangeal joint to have either a ‘firebreak’ skin graft (39 patients, 41 hands, 44 fingers) or a fasciectomy (40 patients, 43 hands, 46 fingers) if, after full correction, the skin over the proximal phalanx could be easily closed by a Z-plasty. Patients were reviewed after three, six, 12, 24 and 36 months to note any complications, the range of movement and recurrence. Both groups were similar in regard to age, gender and factors considered to influence the outcome such as bilateral disease, family history, the presence of diabetes, smoking and alcohol intake. The degree of contracture of the metacarpophalangeal and
Aim. To examine the mid-term survival, clinical and patient reported outcomes of the silastic 1. st. metatarsophalangeal joint replacement for the treatment of end stage hallux rigidus. Methods. We reviewed 83 consecutive silastic arthroplasties performed in 79 patients for end stage hallux rigidus. There were 3 men and 76 women; mean age 63 years (range 45–78 years). No patient was lost to follow up. Average follow-up was 5.3 years (1.1–11.3 years). The EQ 5D–5L Health index, Manchester-Oxford Foot Questionnaire (MOXFQ), visual analogue scale (VAS) of pain and overall satisfaction rate (Likert scale) were collected for patient reported outcomes. Results. 2 patients required revision; 1 for early infection (2 months) and 1 for stem breakage (10 years 1 month). 5 patients reported lateral metatarsalgia, 2 patients reported neuropathic pain, 6 patients developed superficial infection which fully responded to oral antibiotics, and 1 patient developed
Aetiology and pathogenesis: The pathogenesis of boutonnière deformity, in the rheumatoid patient is usually quite clear, and is due to either a central slip failure or volar subluxation of the middle phalanx. This subluxation is seen more commonly in the patients with psoriatic arthropathy. The most common cause is a chronic synovitis of the proximal interphalangeal joint leading to attenuation of the sagital fibres between the central slip and the lateral bands and at a later stage disruption or attenuation of the central slip itself. Synovitis of the pip joint with separation of the lateral bands from the central slip allows the lateral bands to sublux forwards to lie anterior to the axis of rotation thus the intrinsics which extend the proximal and distal joints of the finger come to act as flexors of the proximal joint and continue to act as extensors to the distal joint. The patient will use the intrinsic muscles and they now have a flexion force upon the PIP joint and hyperextension force on the DIP joint, causing a boutonnière deformity. Volar subluxation of the middle phalanx draws forwards the lateral bands and defunctions the central slip creating the same imbalance. Scarring of the volar plate as is seen in volar plate injuries with the production of a pseudo-boutonnière deformity is sometimes seen in psoriatic arthropathy. In a boutonnière deformity the PIP joint is flexed and the DIP joint is extended. With the joints in this position, the origin and insertion of the intrinsic muscles are closer together, and as a consequence, with the passing of time, the muscles fibres will remodel in a shortened position, creating a lateral band tightness. Classification: Boutonnière deformity can be classified into four stages. Type I. The deformity is totally correctable passively, and there is full flexion of the DIP joint when the PIP joint is fully extended. The patient has a passively correctable flexion deformity of the PIP joint, and can actively flex the distal

External fixation is useful for the treatment of selected injuries to the hand. Some authors have suggested that external fixation of a phalanx may tether the extensor hood, thereby hindering active movements and predisposing to permanent adhesions. There is no consensus as to the best site for placement of the pin to minimise these problems. This study was performed on cadaver specimens to investigate the influence of the pin site on the range of simulated active movement of the
The aim of this study was to explore whether adverse reactions would occur during the material’s degradation period even at a later time point after surgery and whether these phenomena were clinically significant and would influence the final outcome. 12 unstable, displaced metacarpal fractures in 10 patients (7 males, 3 females; mean age 36.4 y, range 18–75 y) were treated with the Inion. ®. OTPSTM Biodegradable Mini Plating System. 9 patients (10 fractures) were available for follow-up (mean 25.6 months, range 14 to 44 m).

This study aims to report the outcomes in the treatment of unstable proximal third scaphoid nonunions with arthroscopic curettage, non-vascularized bone grafting, and percutaneous fixation. This was a retrospective analysis of 20 patients. All cases were delayed presentations (n = 15) or failed nonoperatively managed scaphoid fractures (n = 5). Surgery was performed at a mean duration of 27 months (7 to 120) following injury with arthroscopic debridement and arthroscopic iliac crest autograft. Fracture fixation was performed percutaneously with Kirschner (K)-wires in 12 wrists, a headless screw in six, and a combination of a headless screw and single K-wire in two. Clinical outcomes were assessed using grip strength, patient-reported outcome measures, and wrist range of motion (ROM) measurements.Aims

Introduction. The operative management for Distal Tibialis Anterior Tendinopathy (DTAT) without rupture has not previously been described. We present 15 cases. Method. of 39 patients diagnosed clinically and radiographically with DTAT, we reviewed the 13 patients who underwent surgery for failure of non-operative management. Assessment included pre and post-operative AOFAS midfoot scoring, clinical examination and post-operative VAS pain scoring. Results. Twelve women (13 feet) and one man (two feet) underwent surgery. Mean age at surgery was 59 years (42 to 76 years). The mean duration of symptoms prior to surgery was one year (5 to 25 months). The mean pre-operative AOFAS score was 50 (23 to 75). Pre-operative MRI showed tendinosis in six tendons and tendinosis with longitudinal split tears in nine tendons. Five of the 14 cases showed some associated degenerative changes of the midfoot. Six tendons were simply debrided and the insertion reinforced with a suture anchor. Nine tendons were augmented with an Extensor Hallucis Longus (EHL) transfer into the medial cuneiform. The mean improvement in AOFAS score was 35 (4 to 57), with mean post-operative pain VAS of 1 (0 to 6.7) at a mean follow-up of 24 months (three to 65). Two patients underwent concomitant procedures on the same foot. Four of the nine treated with EHL transfer have some symptomatic hallux
Introduction: We present 34 patients diagnosed with hallux rigidus treated by percutaneous surgery. We analyzed the surgical techniques used and the functional results achieved. Materials and methods: We retrospectively collected 34 patients (24 women). Patients were stratified by means of parametric x-rays (Hanft classification from 1 to 4). Treatment consisted in a double osteotomy, also known as Keller’s technique, using percutaneous procedures. The postoperative protocol consisted of walking, use of orthopedic footware, and early mobilization. Results: Mean age was 68.78 years and mean follow-up was 31.45 months. Mean time from first clinical visit to surgery was 4.38 years; most patients had received conservative treatment. The mean degree of hallux rigidus according to the standard classification was 2.5. The mean value of the metacarpophalangeal joint arc and
Introduction: Dorsally angulated metaphyseal fractures of the proximal phalanges usually occur in the middle aged or elderly and are common. Reduction is difficult to maintain with non-operative treatment, due the action of the intrinsic muscles. Most techniques advocated in the literature suggest a transmetacarpal K-wire fixation. We present the results of a simple method of stabilisation using intramedullary K-wires without violating the articular surface. Methods: Over a three-year period, sixty patients with these fractures were treated in this way. A single wire is inserted through the rim of the proximal phalangeal base with MCPJ fully flexed, avoiding transfixion of the collateral ligament. The wire is passed up the medullary canal, across the fracture and up either to subchondral bone or to engage the opposite cortex. The metacar-pophalangeal joints were immobilised with a thermoplastic splint in full flexion and
Introduction: The metacarpophalangeal joint of the thumb is prone to frequent injury in the capsule and collateral ligaments, especially the ulnar collateral ligament. Delayed diagnosis, inappropriate treatment or progressive laxity of the ligament complex can lead to chronic instability of the MCP joint of the thumb. Various surgical repair procedures have been described. We present the surgical procedure consisting of a bone-retinaculum-bone autograft taken from the second tunnel of the flexor retinaculum of the carpus. Purpose: Our purpose is to present the experience of seven cases in which chronic instability of the thumb was treated using a bone-retinaculum-bone autograft. Materials and methods:. Type of study: Descriptive. Period: 2003–2004. Number of cases: 7 (4 women and 3 men) aged 23 to 65. Injury-to-surgery time more than one year.

The 66 patients (78 fingers) who form the basis of this study all sustained complete laceration of the flexor profundus and superficialis tendons in "no man's land". Results were evaluated by the Strickland formula of total active motion (TAM) of the proximal and distal
Background: The results of operative management for distal tibialis anterior tendinopathy (DTAT) without rupture have not previously been described in the orthopaedic literature. We present the results of 15 operative procedures. Method: Of 40 patients diagnosed clinically and radiographically with DTAT, we reviewed the 13 patients who underwent surgery for failure of non-operative management. Assessment included pre and postoperative AOFAS midfoot scores, clinical examination and postoperative VAS pain scoring. Results: Twelve women (13 feet) and one man (2 feet) underwent surgery. The mean age at surgery was 59 years. The mean duration of symptoms prior to surgery was 1 year. The mean pre-operative AOFAS score was 53. Preoperative MRI showed tendinosis with longitudinal split tears in 10 tendons and tendinosis alone in two tendons. Seven of the 15 cases showed some associated degenerative changes of the midfoot. Six tendons were simply debrided and the insertion reinforced with a suture anchor. Nine tendons were augmented with an Extensor Hallucis Longus (EHL) transfer into the medial cuneiform. All patients improved postoperatively, with a mean improvement in AOFAS score of 32 and the mean postoperative pain VAS of 1.0 out of 10, at a mean follow-up of 24 months.

Aim: The purpose of this prospective study was an evaluation of results in primary treatment of flexor tendon laceration in zone II. Special emphasis has been given to the postoperative rehabilitation program. Material and Methods: Nineteen patients, (23 fingers), with laceration of the flexor tendons in zone II were treated operatively. Twelve males and seven females were included in the study. Their mean age was 28 (range, 16 to 50) years. In twelve cases a concomitant laceration of the digital nerve was present, hi all cases primary repair of all injured tendons and nerves was performed and a dorsal splint was applied. On third to fifth postoperative day an exercise program commenced involving passive flexion-active extension of the injured fingers. Eighteen (22 fingers) of 19 patients completed the follow-up. Results: The results were estimated according to Strickland’s original classification system. In fifteen cases the result was excellent, in five good, and in two fair. Conclusions: After primary repair of injured flexor tendons, close follow-up, early protected motion and unrestricted motion of the
Giant cell tumour of tendon sheath is usually benign in nature but their tendency to recur is well known, this cause problems for surgeons and there is always a puzzle in determining the appropriate therapy. This study was done to highlight characteristics, differential diagnosis and current options of treatment for giant cell tumour of tendon sheath. We report two cases treated at our hospital. Both are females, one of 24 years while other was 65 years at the time of diagnosis. First patient had incidental associated benign teratoma of ovary as well. One tumour was of thumb in non dominant hand while in older patient it was at distal

Purpose of the study: Amputation of the thumb is a serious hand injury producing a major functional and aesthetic handicap. In 1980, Foucher proposed a twisted two toes transfer associating elements harvested from the first and second toes on the same pedicle for the reconstruction of an ‘articulated’ thumb with preserved potential for growth. Material and method: Since 2002, two children aged 10 and 14 years underwent this procedure. The thumb amputation was trans MP for one and at the base of P1 for the second. The transfer associated a sheath of skin from the hallux to wrap around the skeleton of the second toe which was harvested as need to the IP or the MP. The aesthetic, functional (400 point scale), and radiological outcomes were assessed. Results: Follow-up was 5 years and 2.5 years. The aesthetic result was comparable to wrap-around transfers. Regarding the functional outcome, the overall hand function was scored 86% and 72% of normal, mobility 77% and 72%, and force 75% and 79%. One patient had persistent deficient active flexion of the
We carried out a cross-sectional study in 51 patients (81 feet) with a clawed hallux in association with a cavus foot after a modified Robert Jones tendon transfer. The mean follow-up was 42 months (9 to 88). In all feet, concomitant procedures had been undertaken, such as extension osteotomy of the first metatarsal and transfer of the tendon of the peroneus longus to peroneus brevis, to correct the underlying foot deformity. All patients were evaluated clinically and radiologically. The overall rate of patient satisfaction was 86%. The deformity of the hallux was corrected in 80 feet. Catching of the big toe when walking barefoot, transfer lesions and metatarsalgia, hallux flexus, hallux limitus and asymptomatic nonunion of the

Extensor tendon attachment to the dorsum of the proximal phalanx may fully extend the finger metacarpal phalangeal joint (MPJ). 15 fresh-frozen cadaveric hands were axially loaded in the line of pull to the extensor digitorum comunis of the index, middle, ring and small finger at the level just proximal to the MPJ. We measured force of extension at the MP joint in 3 groups: 1) native specimen, 2) extensor tendon release at the proximal
OBJECTIVE: The purpose of this study were to present a new surgical classification, based on types of injuries, and to evaluate significance of our post-operative protocol for fingertip replantation, especially crush-avulsion cases. METHODS:Twenty fingertip amputations in 20 consecutive patients were replanted at our institute for recent 5 years. There were 17 male patients and 3 female patients, ranging in age from 19 to 62 years(mean,45.3years). All cases were classified as crush and avulsion according to Yamano. There were 13 amputations in Zone I and 7 in Zone II according to Tamai’s classification for the level of amputation. Also, we classified our cases based on the type of injury. [New Classification] Type IA: Distal transverse palm arterial arch (DTPA) is remained in the proximal part Type IB: DTPA is remained in the amputated part Type II : Loss of DTPA There were 4 cases in Type IA, 4 in Type IB, and 12 in Type II. Postoperatively, 12000–24000U of urokinase and 500 ml of low molecular-weight dextran were given intravenously for 7 consecutive days. In very severe crush/avulsion cases, 10000–15000 U of heparin were given intravenously for 5 days additionally. RESULTS: The overall survival rate of the 20 replantations was 90.0% (zone I:83.3%, Zone II:100%). The survival rate was 100% in type IA, 100% in type IB, and 83.3% in type II. For arterial repair, vein grafts were necessary in 1 of 4 type IA(25%), 1 of 4 type IB(25%), and 11 of 12 type II(91.7%). In 3 of 4 type IA, end to end anastomosis were possible by the technique of transpositioning DTPA. In 3 of 4 type IB, proper digital artery was anastomosed to central artery of the pulp. Regarding functional outcomes with a follow-up period greater than 6mons, excellent cases were 87.0% (according to Tamai’s functional classification). The mean range of motion of the distal
Used routinely in maxillofacial reconstructive surgery, the chondrocostal graft is also applied to hand surgery in traumatic or pathologic indications. The purpose of this overview was to analyze at long-term follow-up the radiological and histological evolution of this autograft, in hand and wrist surgery. We extrapolated this autograft technique to the elbow by using perichondrium. Since 1992, 148 patients have undergone chondrocostal autograft: 116 osteoarthritis of the thumb carpometacarpal joint, 18 radioscaphoid arthritis, 6 articular malunions of the distal radius, 4 kienbock's disease, and 4 traumatic loss of cartilage of the proximal
Upper limb amputations, ranging from transhumeral to partial hand, can be devastating for patients, their families, and society. Modern paradigm shifts have focused on reconstructive options after upper extremity limb loss, rather than considering the amputation an ablative procedure. Surgical advancements such as targeted muscle reinnervation and regenerative peripheral nerve interface, in combination with technological development of modern prosthetics, have expanded options for patients after amputation. In the near future, advances such as osseointegration, implantable myoelectric sensors, and implantable nerve cuffs may become more widely used and may expand the options for prosthetic integration, myoelectric signal detection, and restoration of sensation. This review summarizes the current advancements in surgical techniques and prosthetics for upper limb amputees. Cite this article:

The aims of this study were to validate the outcome of total elbow arthroplasty (TEA) in patients with rheumatoid arthritis (RA), and to identify factors that affect the outcome. We searched PubMed, MEDLINE, Cochrane Reviews, and Embase from between January 2003 and March 2019. The primary aim was to determine the implant failure rate, the mode of failure, and risk factors predisposing to failure. A secondary aim was to identify the overall complication rate, associated risk factors, and clinical performance. A meta-regression analysis was completed to identify the association between each parameter with the outcome.Aims

The purpose of this study was to retrospectively review the outcomes of percutaneous flexor tenotomies of diabetic claw toes with ulcers or pending ulcers. A retrospective chart review between January 1999 and June 2005 was performed to identify those patients that had undergone a percutaneous flexor tenotomy for diabetic claw toe deformities. Thirty-four toes in fourteen patients were identified. Twenty-four toes had ulcerations at the terminal aspect and three of these had radiographic evidence of osteomyelitis of the terminal phalange. All patients had palpable pulses and good capillary refill. A percutaneous flexor tenotomy was performed in an outpatient clinic on all toes, patients with a rigid flexor contracture at the proximal

In the UK, fasciectomy for Dupuytren’s contracture is generally performed under general or regional anaesthetic, with an arm tourniquet and in a hospital setting. We have changed our practice to use local anaesthetic with adrenaline, no arm tourniquet, and perform the surgery in a community setting. We present the outcome of a consecutive series of 30 patients. Prospective data were collected for 30 patients undergoing open fasciectomy on 36 digits (six having two digits affected), over a one-year period and under the care of two surgeons. In total, 10 ml to 20 ml volume of 1% lidocaine with 1:100,000 adrenaline was used. A standard postoperative rehabilitation regime was used. Preoperative health scores, goniometer measurements of metacarpophalangeal (MCP), proximal interphalangeal (PIP) contractures, and Unité Rheumatologique des Affections de la Main (URAM) scores were measured pre- and postoperatively at six and 12 weeks.Aims

Objective: To challenge the validity of using biomarker concentrations in synovial fluid for the assessment of joint pathology. Hypothesis: Synovial fluid biomarker concentrations are influenced by both cartilage and synovial fluid volumes. Methods: Synovial fluid volumes were determined from the equine metacarpophalangeal (MCP), proximal inter-phalangeal (PIP) and distal
Apoptosis of articular chondrocytes may play an important role in the pathogenesis of osteoarthritis (OA). The aim of this study was to investigate the incidence of chondrocyte apoptosis in equine articular cartilage (AC) specimens and examine the relationship between the process of cell death and the degree of cartilage degradation. The study comprised 2 populations of equine cartilage taken from the left forelimb. Population 1 (n=10) consisted of full depth cartilage from weight-bearing regions of equine metacarpophalangeal (MCP), proximal interphalangeal (PIP) and distal
Introduction: Mitchell’s operation is a double step-cut osteotomy through the neck of first metatarsal (MT) which displaces laterally and plantar flexes the metatarsal head and minimally shortens the first MT. In coexisted further forefoot abnormalities this osteotomy can be combined by additional corrective osteotomies of the rest metatarsals and straightening of toes. Material and Methods: A prospective study was carried out in our Department, on 42 patients (51feet) operated with this osteotomy alone or combined. The mean follow-up time was 10 years (range, 3–15 years). The average age of patients was 58 years. The average angle of HV deformity was 38 degrees (in nine feet this angle was more than 40 degrees). Mean inter-metatarsal (IM) angulation was 15 degrees. The procedure was always followed by Y or V capsuloplasty of first metatarsophallangeal (MTP) joint. Moderate arthritis of first MTP joint was not considered by us as a contraindication for this operation. The osteotomy was secured by two crossed K-wires. In 20 feet (15 patients) with coexisted forefoot abnormalities oblique osteotomies of the rest metatarsals, arthrodeses of proximal
Allogeneic bone is one of the most commonly used tissue grafts, with a variety of applications in orthopaedic surgery. The aim of this work is to analyze the initial results obtained using allografts in reconstructive surgery of the hand. In the period between January 2000 and August 2003, eight patients between 16 and 52 years of age (average age: 36 years) were treated using an allograft to replace the metacarpal bone and/or phalangeal bone of the hand. In three cases the initial cause was a recurring neoplasm (aneurysm, cyst, osteoma, osteoid, and TGC); in the other patients the aetiology was traumatic. The site of reconstruction was a metacarpal bone in three patients; in two of these it was associated with reconstruction of MPj (in one patient there was double bone loss at the third and fourth metacarpal bone); in one patient the lesion affected only the MPj. In the other five patients the reconstruction was performed at the phalanx, transferring the proximal
Little is known about tissue changes underlying bone marrow lesions (BMLs) in non-weight-bearing joints with osteoarthritis (OA). Our aim was to characterize BMLs in OA of the hand using dynamic histomorphometry. We therefore quantified bone turnover and angiogenesis in subchondral bone at the base of the thumb, and compared the findings with control bone from hip OA. Patients with OA at the base of the thumb, or the hip, underwent preoperative MRI to assess BMLs, and tetracycline labelling to determine bone turnover. Three groups were compared: trapezium bones removed by trapeziectomy from patients with thumb base OA (n = 20); femoral heads with (n = 24); and those without (n = 9) BMLs obtained from patients with hip OA who underwent total hip arthroplasty.Objectives
