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 interphalangeal joint extension or hyperextension. Severe metacarpophalangeal joint hyperextension (> 40°) was documented in 15 cases (22%). The median QuickDASH score was 0 (0 to 61), indicating excellent function at a median follow-up of 15 years (10 to 19). Overall satisfaction was high, with 56 patients (84%) reporting the maximal satisfaction score of 5. Among 37 patients who underwent surgery at age ≤ two years, 34 (92%) reported the largest satisfaction, whereas this was the case for 22 of 30 patients (73%) with surgery at aged > two years (p = 0.053). Notta’s nodule resolved in 49 patients (73%) at final follow-up. No residual triggering or revision surgery was observed. Conclusion. Surgical release of A1 pulley in paediatric trigger thumb is an acceptable procedure with excellent functional long-term outcomes. There was a trend towards higher satisfaction with earlier surgery among the patients. Cite this article: Bone Jt Open 2024;5(9):736–741

Aims. Complete ruptures of the ulnar collateral ligament (UCL) of the thumb are a common injury, yet little is known about their current management in the UK. The objective of this study was to assess the way complete UCL ruptures are managed in the UK. Methods. We carried out a multicentre, survey-based cross-sectional study in 37 UK centres over a 16-month period from June 2022 to September 2023. The survey results were analyzed descriptively. Results. A total of 37 centres participated, of which nine were tertiary referral hand centres and 28 were district general hospitals. There was a total of 112 respondents (69 surgeons and 43 hand therapists). The strongest influence on the decision to offer surgery was the lack of a firm ‘endpoint’ to stressing the metacarpophalangeal joint (MCPJ) in either full extension or with the MCPJ in 30° of flexion. There was variability in whether additional imaging was used in managing acute UCL injuries, with 46% routinely using additional imaging while 54% did not. The use of a bone anchor was by far the most common surgical option for reconstructing an acute ligament avulsion (97%, n = 67) with a transosseous suture used by 3% (n = 2). The most common duration of immobilization for those managed conservatively was six weeks (58%, n = 65) and four weeks (30%, n = 34). Most surgeons (87%, n = 60) and hand therapists (95%, n = 41) would consider randomizing patients with complete UCL ruptures in a future clinical trial. Conclusion. The management of complete UCL ruptures in the UK is highly variable in certain areas, and there is a willingness for clinical trials on this subject.

Injectable collagenase is an alternative to surgical treatment for Dupuytren’s disease. Previous studies have reported on the effectiveness of collagenase in finger contractures. This prospective study reports on the short-term safety and efficacy of collagenase treatment in five thumb and first web space Dupuytren’s contractures. The thumb and first web space contractures were treated with injectable collagenase in four consecutive patients (five hands) with experience of previous surgical digital fasciectomy. The thumb contracture was measured by angle and span in two planes of thumb extension and abduction before injection and after manipulation. Collagenase treatment resulted in release of the contracture with a mean increase in thumb to index angle from 23° (10° to 35°) to 56° (45° to 60°) in extension and from 30° (10° to 50°) to 58° (50° to 65°) in abduction and a mean increase in span from 1.9 cm (1 to 3.5) to 3.9 cm (3 to 5) in extension and from 2.4 cm (1.5 to 3.5) to 3.9 cm (3 to 4.5) in abduction. All patients reported an increased range of movement and function and described collagenase therapy as preferable to surgery. In the short-term collagenase is an effective, well-tolerated and safe alternative to surgery for Dupuytren’s disease of the thumb

Aims. Osteoarthritis (OA) affecting the thumb carpometacarpal joint (CMCJ) is a common painful condition. In this study, we aimed to explore clinicians’ approach to management with a particular focus on the role of specific interventions that will inform the design of future clinical trials. Methods. We interviewed a purposive sample of 24 clinicians, consisting of 12 surgeons and 12 therapists (four occupational therapists and eight physiotherapists) who managed patients with CMCJ OA. This is a qualitative study using semi-structured, online interviews. Interviews were audio-recorded, transcribed verbatim, and analyzed using thematic analysis. Results. A total of 14 themes were developed, six of which were developed relating to the clinical management of CMCJ OA: 1) A flexible ‘ladder’ approach starting with conservative treatment first; 2) The malleable role of steroid injection; 3) Surgery as an invasive and risky last resort; 4) A shared and collaborative approach; 5) Treating the whole person; and 6) Severity of life impact influences treatment. The remaining eight themes were developed relating to clinical trial barriers and facilitators: 1) We need to embrace uncertainty; 2) You are not losing out by taking part; 3) It is difficult to be neutral about certain treatments; 4) Difficult to recruit to ‘no treatment’ ; 5) Difficult to recruit to a trial comparing no surgery to surgery; 6) Patients are keen to participate in research; 7) Burden on staff and participants; and 8) A enthusiasm for a variety of potential trial arms. Conclusion. Our findings contribute to a better understanding of how clinicians manage thumb CMCJ OA in their practice settings. Our study also provides useful insights informing the design of randomized clinical trials involving steroid injections and surgery in people with thumb CMCJ OA.

Aims. The aim of this study was to assess arthritis of the basal joint of the thumb quantitatively using bone single-photon emission CT/CT (SPECT/CT) and evaluate its relationship with patients’ pain and function. Methods. We retrospectively reviewed 30 patients (53 hands) with symptomatic basal joint arthritis of the thumb between April 2019 and March 2020. Visual analogue scale (VAS) scores for pain, grip strength, and pinch power of both hands and Patient-Rated Wrist/Hand Evaluation (PRWHE) scores were recorded for all patients. Basal joint arthritis was classified according to the modified Eaton-Glickel stage using routine radiographs and the CT scans of SPECT/CT, respectively. The maximum standardized uptake value (SUVmax) from SPECT/CT was measured in the four peritrapezial joints and the highest uptake was used for analysis. Results. According to Eaton-Glickel classification, 11, 17, 17, and eight hands were stage 0 to I, II, III, and IV, respectively. The interobserver reliability for determining the stage of arthritis was moderate for radiographs (k = 0.41) and substantial for CT scans (k = 0.67). In a binary categorical analysis using SUVmax, pain (p < 0.001) and PRWHE scores (p = 0.004) were significantly higher in hands with higher SUVmax. Using multivariate linear regression to estimate the pain VAS, only SUVmax (B 0.172 (95% confidence interval (CI) 0.065 to 0.279; p = 0.002) showed a significant association. Estimating the variation of PRWHE scores using the same model, only SUVmax (B 1.378 (95% CI, 0.082 to 2.674); p = 0.038) showed a significant association. Conclusion. The CT scans of SPECT/CT provided better interobserver reliability than routine radiographs for evaluating the severity of arthritis. A higher SUVmax in SPECT/CT was associated with more pain and functional disabilities of basal joint arthritis of the thumb. This approach could be used to complement radiographs for the evaluation of patients with this condition. Cite this article: Bone Joint J 2021;103-B(8):1380–1385

Objectives. 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. Methods. 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. Results. All trapezium bones demonstrated MRI-defined BMLs. Compared with femoral heads without BMLs, the trapezia demonstrated significantly higher bone turnover (mean . sd. 0.2 (0.1) versus 0.01 (0.01) µm. 3. /µm. 2. /day), mineralizing surface (18.5% (13.1) versus 1.4% (1.3)) and vascularity (5.2% (1.1) versus 1.2% (0.6)). Femoral heads with BMLs exhibited higher bone turnover (0.3 (0.2) versus 0.2 (0.1) µm. 3. /µm. 2. /day), a higher mineralization rate (26.6% (10.6) versus 18.6% (11.9)) and greater trabecular thickness (301.3 µm (108) versus 163.6 µm (24.8)) than the trapezia. Conclusion. Bone turnover and angiogenesis were enhanced in BMLs of both the thumb base and hip OA, of which the latter exhibited the highest bone turnover. Thus, the increase in bone turnover in weight-bearing joints like the hip may be more pronounced than less mechanically loaded osteoarthritic joints demonstrating BMLs. The histological changes observed may explain the water signal from BMLs on MRI. Cite this article: M. Shabestari, N. J. Kise, M. A. Landin, S. Sesseng, J. C. Hellund, J. E. Reseland, E. F.

Aims. Base of thumb osteoarthritis (BTOA) is a common age-related disease which has a significant negative impact upon quality of life. Our aim was to assess current UK practice in secondary care with regard to the nature of non-surgical treatments, the surgical procedures most commonly performed, and factors influencing the surgical decision-making process. Methods. Ten consecutive patients undergoing surgery for BTOA between March 2017 and May 2019 were prospectively identified in 15 UK centres. Demographic details, duration of symptoms, radiological grade, non-surgical management strategies, and surgery conducted were recorded. A supplementary consultant questionnaire consisting of four multiple-choice-questions (MCQ) based on hypothetical clinical scenarios was distributed. Results. A total of 150 patients were identified with a mean age of 64 years (SD 9), comprising 119 females and 31 males. Median duration of symptoms prior to surgery was 24 months (Interquartile range (IQR) 12 to 40). Hand therapy was used in 67 patients (45%), splints in 80 (53%), and 121 patients (81%) received one or more intra-articular injections, of which 81 (67%) were image-guided (14 (12%) ultrasound and 67 (55%) fluoroscopic). Only 48 patients (32%) received all three non-surgical treatments. Simple trapeziectomy (79 patients) and trapeziectomy with ligament reconstruction and/or tendon interposition (69 patients) were the most commonly performed operations. One patient was treated with arthrodesis, and one with arthroplasty. The supplementary questionnaire revealed that no specific patient or disease characteristics significantly influenced the type of surgery undertaken. Conclusion. We found considerable variation in practice of both non-surgical and surgical management of BTOA. The proportion of patients exhausting non-surgical strategies before being offered surgery is low. Surgeons tend to favour a single type of surgery irrespective of patient or disease characteristics. Cite this article: Bone Joint J 2020;102-B(5):600–605

We report a new surgical technique for the treatment of traumatic dislocation of the carpometacarpal (CMC) joint of the thumb. This is a tenodesis which uses part of the flexor carpi radialis. . Between January 2010 and August 2013, 13 patients with traumatic instability of the CMC joint of the thumb were treated using this technique. The mean time interval between injury and ligament reconstruction was 13 days (0 to 42). The mean age of the patients at surgery was 38 years: all were male. . At a mean final follow-up of 26 months (24 to 29), no patient experienced any residual instability. The mean total palmar abduction of the CMC joint of the thumb was 61° and the mean radial abduction 65° The mean measurements for the uninjured hand were 66° (60° to 73°) and 68° (60° to 75°), respectively. The mean Kapandji thumb opposition score was 8.5° (8° to 9°). The mean pinch and grip strengths of the hand were 6.7 kg (3.4 to 8.2) and 40 kg (25 to 49), respectively. The mean Disabilities of the Arm, Shoulder, and Hand questionnaire score was 3 (1 to 6). Based on the Smith and Cooney score, we obtained a mean score of 85 (75 to 95), which included four excellent, seven good, and two fair results. Our technique offers an alternative method of treating traumatic dislocation of the CMC joint of the thumb: it produces a stable joint and acceptable hand function.

1. Absence of a thumb, whether congenital or due to injury, is a severe disability. Reconstructive surgery has much to offer. 2. Pollicisation is the most satisfactory method, being the only means of providing a thumb with normal tactile sensibility. The importance of this has often been overlooked and has been emphasised by Moberg (1958). Pollicisation offers also the best functional and aesthetic results. When applicable, the neurovascular pedicle technique of Littler is the one of choice. It is indicated in group 2 cases associated with a partly amputated finger, when this is swung on to the thumb stump, and for patients in groups 3 and 4 when the normal index finger is used. If this method is not feasible a staged pollicisation may be used instead. 3. The Gillies method of thumb lengthening has a more limited application, but it is valuable in selected cases. 4. Reconstruction by tubed pedicle and bone graft is seldom indicated and is best reserved for reconstruction in the mutilated hand when local elements are deficient. 5. Replacing a thumb by a toe should be reserved for exceptional cases. 6. Autografting the amputated thumb is feasible, and should be considered when the amputated digit has been preserved

1. A technique of arthrodesis of the trapezio-metacarpal joint of the thumb is described. Primary fusion was achieved in thirty-six of thirty-nine cases. 2. Compensatory movement at the adjacent joints permits a good range of thumb movement. 3. Trapezio-metacarpal arthrodesis is the operation of choice for patients under fifty with isolated osteoarthritis of this joint. It is also useful for stabilising the thumb in patients with paralysis of the thumb when adequate muscles for transfer are not available

We examined prospectively 4719 newborn infants to determine the congenital incidence of trigger thumb. No cases were found. Fifteen other children aged from 15 to 51 months had surgery for this condition. The anomaly had not been seen at birth and all thumbs presented with a flexion contracture without triggering. The condition is usually seen after birth as a flexion contracture of the interphalangeal joint. The term ‘congenital’ is a misnomer because patients acquire the deformity after birth. The term ‘trigger’ is inaccurate as most thumbs show a fixed-flexion contracture without triggering. We suggest that rather than ‘congenital trigger thumb’ a more appropriate description of this disorder is ‘acquired thumb flexion contracture in children’. If the contracture persists after one year of age, treatment by dividing the A-1 pulley is simple and effective

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 interphalangeal joints is not related to the presence of a sesamoid bone in the anterior part of the capsule of the joint. 10. The surfaces of the metacarpo-phalangeal joints vary considerably in shape. Those which are flat form about 10 per cent. of the sample and do not show hyperextension. 11. The factors influencing the amount of extension at the interphalangeal joint is the degree of laxity of the anterior capsule. The problem at the metacarpo-phalangeal joint is more complex; both the capsule and the shape of the joint surfaces play important roles

1 . Three cases of triphalangeal thumb are described in three generations of a Bantu family. In the youngest member both thumbs were affected; in his mother and grandfather only one thumb was abnormal. 2. The literature is reviewed and the etiology of the anomaly is discussed. 3. Attention is drawn to the hereditary tendency of this condition

The uncommon injury of mallet thumb is described, with four case reports. In diagnosis the condition must be distinguished from dropped thumb. Operative treatment is advised which, in this small series, gave excellent results

There are few reports describing dislocation of the metacarpophalangeal joint of the thumb in children. This study describes the clinical features and outcome of 37 such dislocations and correlates the radiological pattern with the type of dislocation. The mean age at injury was 7.3 years (3 to 13). A total of 33 children underwent closed reduction (11 under general anaesthesia). Four needed open reduction in two of which there was soft-tissue interposition. All cases obtained a good result. There was no infection, recurrent dislocation or significant stiffness. So-called ‘simple complete’ dislocations that present with the classic radiological finding of the joint at 90° dorsal angulation may be ‘complex complete’ injuries and require open reduction

Immobilisation of the thumb is widely believed to be important in the management of fractures of the carpal scaphoid. To assess the need for this, we randomly allocated 392 fresh fractures for treatment by either a forearm gauntlet (Colles') cast, leaving the thumb free, or by a conventional 'scaphoid' plaster incorporating the thumb as far as its interphalangeal joint. In the 292 fractures which were followed for six months, the incidence of nonunion was independent of the type of cast used

1. The pedigree of a family in which lobster claw foot and triphalangeal thumb occurred together is presented. The affected members of two generations are described. The clinical appearances and radiological abnormalities are described in detail. Results of surgical treatment of the forefoot cleft are presented. 2. Lobster clawing of the foot is discussed with particular reference to associated hand and finger abnormalities. Triphalangeal thumb is discussed. The current and probably acceptable theory of the etiology of duplication is expanded. A hypothesis is formulated of excessive activity at the pre-and post-axial borders of the distal limb bud, followed by variable resorption, to explain not only the cause of lobster claw foot but also its occurrence in association with triphalangeal thumb

1 . A method of restoring protective sensibility to the thumb by a neurovascular pedicle graft is described. 2. The pedicle is taken from the dorsum of the index finger. 3. The method has been modified to include a racquet-shaped skin flap to give continuous sensibility from the pulp down the antero-medial border of the thumb

We have assessed the results of 34 simple excisions of the trapezium, with no additional soft-tissue procedures, in 30 patients. At a median follow-up of five years (2 to 22), 16 thumbs (47%) were completely painfree and a further 10 (29%) were slightly painful after use. Nineteen thumbs (56%) had no functional disability, but thumb-pinch strength was reduced by about 20%. No patient had painful degeneration at the scaphotrapezial pseudarthrosis

Our aim was to determine the outcome of the treatment of trigger thumb in children. There was a rate of spontaneous recovery of 49% in those children whose thumbs were observed before a final decision to operate was made. Spontaneous recovery occurred more commonly in children over 12 months old. All patients treated by operation had a satisfactory outcome with few complications. The overall rate of recurrence was 4.0% and it was more common in younger children. Our results suggest that a conservative approach to surgery for this condition could be adopted

The digital nerves to the thumb and index finger have been studied by dissecting twenty-five embalmed upper limbs. The palmar digital nerves to the thumb were constant in position and course, with a short lateral cutaneous branch from the radial palmar digital nerve in 30 per cent of cases. The palmar digital nerves to the index finger had a variable pattern, the commonest arrangement, well described in Gray's Anatomy, occurring in 74 per cent of cases. The variations and their frequency are described. By examining histological cross-sections of the index finger it was found that of about 5,000 endoneurial tubes entering the finger, 60 per cent passed beyond the distal digital crease to supply the pulp and nail bed. The depth of the palmar digital nerves was about 3 millimetres, but less at the digital creases, and their diameter lay between 1 and 1·5 millimetres as far as the distal digital crease. Clinical applications of the findings are discussed

In nine patients of median age 34 years who had sustained an amputation of the thumb at a median 24 (5 to 131) months previously, we lengthened the first metacarpal by 30 (17 to 36) mm. Seven amputations had been through the proximal phalanx and two through the metacarpal. The first two patients had autogenous grafting at a second stage, but the other seven had callotasis alone. In these patients the external fixators were removed at a median 189 (115 to 271) days after osteotomy. In six cases the adductor pollicis tendon was transferred proximally and the first web deepened. There was late fracture or palmar flexion of the callus in five patients, but this required further surgery in only one. Treatment was complete at 326 (140 to 489) days after osteotomy. The extended thumb retained its sensitivity; both grasp and key-pinch strength were satisfactory and only one patient felt that the result did not warrant the long course of treatment. Metacarpal lengthening by this method is a prolonged procedure, but provides a valuable alternative to more complex reconstructions

1. A family is reported in which tibial aplasia with polydactyly of hands and feet and absent thumbs occurred in a father and daughter. 2. The evidence suggests the existence of an autosomal dominant mutant gene that causes absent thumbs and manual polydactyly, with or without varying degrees of tibial hypoplasia and pedal polydactyly

1. The pathological anatomy of total rupture of the ulnar collateral ligament of the metacarpo-phalangeal joint of the thumb has been studied at operation in thirty-nine patients. 2. It has been found that the ligament, when ruptured distally (the most usual type) is often displaced so that the ulnar expansion of the dorsal aponeurosis–here referred to as the adductor aponeurosis–becomes interposed between the ruptured end of the ligament and the site of its attachment on the phalanx; the ligament gets folded over to a greater or lesser extent and the ruptured end sticks out beyond the proximal edge of the adductor aponeurosis. Such displacement of the ligament with interposition of the adductor aponeurosis was found in twenty-five of the thirty-nine cases. The ligament may also be displaced without the adductor aponeurosis being interposed (with a gap between the ruptured end and the site of itsattachment on the phalanx). 3. Variations in the pathological anatomy are illustrated by more detailed descriptions of nine cases. In one of these the adductor aponeurosis had got caught between the two surfaces of the joint, and in another the adductor aponeurosis was found ruptured as well as the ulnar collateral ligament. 4. On the basis of dissection studies on forty-two fresh post-mortem specimens, a rational explanation is given of the pathological anatomy. 5. The results of the present investigation on clinical and anatomical material provide a strong argument in favour of operative treatment for total rupture of the ulnar collateral ligament of the metacarpo-phalangeal joint of the thumb. 6. Aspects of diagnosis and operative technique are discussed

1. A modified method of stabilisation of the thumb of the spastic hand is described whose rigidity overcomes the difficulty of maintaining a good position while fusion is proceeding. 2. The method seems to have a place in the management of suitably selected patients with severe spastic thumb-in-palm

We report the reconstruction of two cases of floating thumb by transplanting the distal two-thirds of the fourth metatarsal. Opponensplasty was performed after six months and resulted in satisfactory morphological and functional results. The metatarsal defect was filled by a full-thickness iliac bone graft including the apophysis. This prevented shortening of the fourth toe and formed a new metatarsophalangeal joint

We used high-resolution ultrasonography to image the ulnar collateral ligament in 39 patients who had sustained recent injuries of the metacarpophalangeal joint of the thumb. All the patients were subsequently operated on and the lesions of the ligament were recorded. In 36 patients the preoperative ultrasonographic diagnosis was correct. Five of these showed no rupture of the ligament. In the other 31, ultrasonography correctly distinguished between rupture in situ (15) and rupture with dislocation of the ligament (16). Misdiagnosis by ultrasonography in three cases was due to delay of the investigation (three weeks after injury) in one, to technical error in one and to misinterpretation of the image in one

In six patients with defective sensibility of the thumb the transfer of a neurovascular island flap was performed according to Littler's technique. This review one to eleven years later was mainly to determine if reorientation of the cortical representation of stimuli had developed and if tactile gnosis had persisted. The pick-up test was carried through by the three patients with a lesion of the dominant hand. All six patients referred pin-prick in the flap to the donor finger; all had absent two-point discrimination corresponding to the flap, although it had been present within normal limits a few months after operation; and all had better touch, pain and temperature sensibility in the flap than in the surrounding recipient area. All six reported functional improvement. For the best results an intelligent patient is required who has a lesion of the dominant hand and is prepared to use or exercise it regularly

1. A series of 149 consecutive cases of flexor tendon grafting in the fingers and thumb is reviewed and the results are analysed. A description of the technique which has evolved from this experience is given. 2. Replacement of a divided flexor digitorum profundus in the presence of an intact sublimis tendon restored a useful range of movement in 80 per cent of cases. 3. Replacement of both flexor digitorum profundus and sublimis gave good results in 70 to 80 per cent of cases. 4. Replacement of a divided flexor pollicis longus tendon gave good results in 85 per cent of cases. 5. The particular tendon used for the graft did not materially influence the result, but there are special indications for the use of the different tendons. 6. The choice of splintage or of early movement after operation does not appear to have a significant bearing upon the result. 7. The most important factor in determining the result is probably a precise and gentle surgical technique and complete haemostasis. Minor differences in method are of little importance. The failures in this series were due more to faulty performance of the operation than to any other single factor

We have studied the restoration of sensation in 24 patients after operations involving the digital nerves of the thumb. These comprised 10 neurorrhaphies, two nerve graftings, five replantations, one toe-to-thumb transfer and six neurovascular island flaps. The average follow-up period was 46 months. Greater sensitivity was found in the moving two-point discrimination (2PD) test than in the static 2PD test. The results of the Semmes-Weinstein test showed good correlation with the static 2PD test. Porter's letter test showed correlations with both 2PD tests, and the pulp-writing test showed good correlation with the moving 2PD test. The neurorrhaphy cases had the best results using the static 2PD and Semmes-Weinstein test, and had good restoration of sensation; the replantation cases were next best. After neurovascular island flaps, patients exhibited hypersensitivity, double sensation and distorted images on the pulp-writing test. Using this same test the nerve grafting cases had distorted touch perception and perceived a straight line as a curve. The pulp-writing test, using moving touch, is one method of examining mechanoreceptors and shows to what extent the patient perceives what touches the finger pulp; it gives a better indication of higher functions than the 2PD test

We report the use of a free tendon graft in 70 patients to repair lesions of the capsuloligamentous complex of the metacarpophalangeal joint of the thumb. Of these 37 had a lesion of the ulnar collateral ligament, 18 of the radial collateral and 11 of the volar plate. Four patients had combined lesions. We outline our techniques and review 51 of the patients. Of those 47 (92%) were satisfied, and all but one had regained full stability. Pinch grip strength was normal in 48. About one-third of the patients had some loss of flexion/extension; this was seldom noticed by the patients and caused no significant disability. Free tendon graft reconstruction is indicated for severe fresh lesions, for old lesions with chronic disability and for lesions which have not responded to conservative management

In 28 patients with a solitary diagnosis of instability of the trapeziometacarpal joint because of a rupture of the anterior oblique ligament, reconstruction was carried out using a slip of the tendon of flexor carpi radialis. We were able to review 26 patients. The results after a follow-up of four years seven months showed that most (87%) had significant relief from pain and symptoms. Seventeen were graded as good to excellent. The mean grip strength recovered to 86% of the contralateral side. Most patients (81%) felt that they had subjective improvement and would have undergone the operation again. A lesser functional result was seen in those who developed a flexion deformity because of overtightening of the reconstruction. Increased awareness of this lesion can lead to an early and clear diagnosis so that the patient may be advised adequately. We describe a specific, diagnostic, clinical test which we have used consistently and successfully.

1. The treatment of Bennett's fracture is reviewed and the relative merits of conservative and operative treatment is considered.

2. A closed method of treatment is described and a series of thirty-one patients so treated is analysed. There were twenty-nine successful results.

3. It is urged that conservative treatment is the method of choice, and that operative measures should be reserved for the occasion when closed methods have failed.

We performed 20 de la Caffiniere trapeziometacarpal arthroplasties for osteoarthritis occurring only at this joint and reviewed all patients after periods of up to ten years. Eighteen arthroplasties were satisfactory postoperatively, although all 20 patients had a satisfactory range of motion and only one experienced pain after surgery such that it impeded normal function. Failure occurred in two patients and was due to overreaming of the trapezium during surgery and a traumatic dislocation. A radiolucency between the prosthesis and bone was observed in one arthroplasty, although this patient was asymptomatic. We recommend arthroplasty using the de la Caffiniere prosthesis as a satisfactory method of treatment for the osteoarthritic trapeziometacarpal joint.

Aims. The aim of this study was to compare the Push Ortho Thumb Brace CMC and a custom-made orthosis in the treatment of patients with primary osteoarthritis of the carpometacarpal joint of the thumb. Our outcome measures were pain scores, tests of hand function, patient satisfaction and patient preference. Patients and Methods. A multicentre crossover randomised controlled trial was conducted which included 63 patients (44 women) with primary osteoarthritis of the carpometacarpal joint of the thumb. Of these, 59 patients with a mean age of 60.1 years (standard deviation 8.2), completed the study. Patients used both orthoses for two weeks with a two-week washout period in-between. Pain was measured on a 10-cm visual analogue scale. Hand function was assessed using the Jebsen Taylor Hand Function test, Nine Hole Peg Test, key grip, pinch grip and Functional Index for Hand Osteoarthritis. Patient preference was assessed using the Dutch version of the Quebec User Evaluation of Satisfaction with Assistive Technology score. Results. Both orthoses resulted in a minor reduction in pain scores without significant difference between the two orthoses. The Push Ortho Thumb Brace CMC interfered less with key grip (p < 0.001) and the Nine Hole Peg Test (p < 0.001) than the custom-made orthosis. The Push Ortho Thumb Brace CMC had a higher patient satisfaction (p < 0.001) and most patients preferred this orthosis for future use. Conclusion. When considering an orthosis for osteoarthritis of the carpometacarpal joint of the thumb, patients may prefer the Push Ortho Thumb Brace CMC. Cite this article: Bone Joint J 2017;99-B:237–44

Aims. The objective of this systematic review was to describe trapeziectomy outcomes and complications in the context of osteoarthritis of the base of the thumb after a five-year minimum follow-up. Methods. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to guide study design, and 267 full-text articles were assessed for eligibility. After exclusion criteria application, 22 studies were included, involving 728 patients and 823 trapeziectomies. Outcomes included pre- and postoperative clinical and radiological characteristics. Complications and revisions were recorded. Results. All the studies reported good results regarding pain and range of motion at the last follow-up of 8.3 years (5 to 22); the mean satisfaction rate was 91% (84% to 100%). It was difficult to assess the impact on metacarpophalangeal joint motion in extension with contrary results. The key pinch returned to its preoperative values, whereas tip pinch showed a modest improvement (+14%), with a mild improvement found in grip strength (+25%) at the last follow-up. The mean progressive trapezial collapse was 48% (0% to 85%) and was not correlated with pain, grip strength, or satisfaction. The most represented complications were linked to tendons or nerves affected during additional procedures to stabilize the joint (11.6%; n = 56). Mechanical complications included symptomatic scapho-M1 impingement (3.1%; n = 15/580), leading to nine surgical revisions out of 581 trapeziectomies. Meta-analysis was not possible due to study heterogeneity and limited data. Conclusion. After a minimum five-year follow-up, trapeziectomy achieved high patient satisfaction and pain relief. However, strength seemed to be deteriorating with detrimental consequences, but this did not correlate with trapezial collapse. The issues related to underestimating mechanical complications and varying degrees of success should be highlighted in the information given to patients. Evidence-based analyses should help the surgeon in their decision-making. Cite this article: Bone Jt Open 2021;2(3):141–149

We have reviewed 11 patients with congenital absence of the thumb, treated by pollicisation of the index finger, after follow-up for 20 to 38 years. Seven of the hands also had an associated radial club-hand deformity. Function as assessed by the Percival score was excellent in six, good in three, fair in two and poor in four; three of the poor results were in patients with radial club hand. Ten of the 15 transfers were used as normal thumbs, but in five hands function required trick movements. Of the seven unilateral cases, two transplants were used as the dominant hand, and in another two thumb strength was more than 50% of that on the opposite side. For patients with isolated congenital absence of the thumb, pollicisation of the index finger gives good functional and cosmetic results which are maintained. The results are less reliable for those with radial club hand

1. Prehension is a complex mechanism for which both movement and sensation are required. 2. Two basic grips are considered: the digital pinch and palmar grasp, which are simpler expressions of the precision grip and the power grip. For the digital pinch the minimum requirement is a thumb or a reconstructed thumb, and a finger to which it can oppose. For palmar grasp mobile fingers are necessary so that they can wrap round the object grasped. 3. The restoration of prehension is considered under the following headings: mutilation of the fingers; mutilation of the thumb; and mutilation of both together. 4. The various methods of reconstruction are described that are appropriate to each type of mutilation, so as to provide restoration of length, mobility and sensation. 5. The indications for the various main methods to compensate for loss of the thumb are discussed. These methods include pollicisation and osteoplastic repair with neurovascular island flap

Aims

The aim of this retrospective study was to evaluate the rate of conversion to surgical release after a steroid injection in patients with a trigger finger, and to analyze which patient- and trigger finger-related factors affect the outcome of an injection.

Aims

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.

Aims

Favourable short-term outcomes have been reported following latissimus dorsi tendon transfer for patients with an irreparable subscapularis (SSC) tendon tear. The aim of this study was to investigate the long-term outcomes of this transfer in these patients.

Aims

It is not clear which type of casting provides the best initial treatment in adults with a distal radial fracture. Given that between 32% and 64% of adequately reduced fractures redisplace during immobilization in a cast, preventing redisplacement and a disabling malunion or secondary surgery is an aim of treatment. In this study, we investigated whether circumferential casting leads to fewer fracture redisplacements and better one-year outcomes compared to plaster splinting.

1. A single case is presented in which the great toe was transferred in one stage to replace an amputated thumb : microvascular techniques were used to anastomose the appropriate vessels. 2. The operative and post-operative complications are described and the final successful result noted. 3. The place of the operation in the future of thumb replacement is briefly discussed

The technique described aims to eliminate the drawbacks of the commonly accepted operative procedures for correction of the spastic "thumb-in-palm" deformity without fusion of the thumb. In all seven patients followed up for one and a half to two years after operation the thumb regained a functional position, being held out of the palm together with the metacarpal without hyperextension of the metacarpo-phalangeal joint

1. Sixteen cases of thenar paralysis are reviewed in which a bone graft was inserted between the first and second metacarpals to maintain fixed abduction and opposition of the thumb. 2. The technique of the operation is described and the causes of failure are discussed. 3. The operation is intended for those cases in which tendon transplantation to restore active opposition of the thumb is unsuitable. Rotation of the first metacarpal into full opposition is the most important feature of the operation

1. A small series of fourteen pollicisations has been studied. 2. The keyword, so far as the operation is concerned, has been simplicity. 3. It has been appreciated that a transposed finger can never become a thumb, and it may not be wise to strive too har1d by means of transplants to emulate the perfection of the normal thumb, especially if this is done at the expense of one of the fundamental priorities. 4. Nevertheless, if sensibility, good position and proximal stability are achieved, pollicisation can provide a useful addition to hand function and a reasonably satisfactory appearance

Aims

The evidence demonstrating the superiority of early MRI has led to increased use of MRI in clinical pathways for acute wrist trauma. The aim of this study was to describe the radiological characteristics and the inter-observer reliability of a new MRI based classification system for scaphoid injuries in a consecutive series of patients.

Crushing of the radial side of the hand results in a wide spectrum of injuries varying from contusion of muscles to total loss. The main problem concerns the function of the thumb. The results of such injuries in 161 hands were reviewed. Those with mild injuries treated conservatively or by debridement alone had good results. When skin flaps were required for wound coverage, the results were still satisfactory. However, when bones and joints were injured, the results were poor. In certain patients opponensplasty through scarred tissue proved to be a good procedure to improve the function of the thumb

Aims

The aim of this study was to develop a core outcome set of what to measure in all future clinical research on hand fractures and joint injuries in adults.

1. Trigger thumbs present at birth can be safely watched for twelve months because there is an expected spontaneous recovery rate of at least 30 per cent. 2. Trigger thumbs in children first noticed between the age of six to thirty months can be safely watched for six months because there is an expected spontaneous recovery rate of about 12 per cent. 3. Delayed operation left no residual contracture of the interphalangeal joint provided the release was done before the age of four years. 4. Operation is recommended if the child is over the age of three years when first seen

1. The prehensile movements of the hand as a whole are analysed from both an anatomical anda functional viewpoint. 2. It is shown that movements of the hand consist of two basic patterns of movements which are termed precision grip and power grip. 3. In precision grip the object is pinched between the flexor aspects of the fingers and that of the opposing thumb. 4. In power grip the object is held as in a clamp between the flexed fingers and the palm, counter pressure being applied by the thumb lying more or less in the plane of the palm. 5. These two patterns appear to cover the whole range of prehensile activity of the human hand

Aims

To compare the cost-effectiveness of high-dose, dual-antibiotic cement versus single-antibiotic cement for the treatment of displaced intracapsular hip fractures in older adults.

Aims

The aim of this study was to describe the introduction of a virtual pathway for the management of patients with a suspected fracture of the scaphoid, and to report patient-reported outcome measures (PROMs) and satisfaction following treatment using this service.

We report a long-term follow-up of abduction-extension osteotomy of the first metacarpal, performed for painful trapeziometacarpal osteoarthritis. Of a consecutive series of 50 operations, 41 thumbs (82%) were reviewed at a mean follow-up of 6.8 years. Good or excellent pain relief was achieved in 80%, and 93% considered that surgery had improved hand function, while 82% had normal grip and pinch strength, with restoration of thumb abduction. Metacarpal osteotomy was equally successful in relieving symptoms of those with early (grade 2) and moderate (grade 3) degenerative changes. This simple procedure provides lasting pain relief, corrects adduction contracture and restores grip and pinch strength, giving good results with few complications

Aims

Current National Institute for Health and Clinical Excellence (NICE) guidance advises that MRI direct from the emergency department (ED) should be considered for suspected scaphoid fractures. This study reports the current management of suspected scaphoid fractures in the UK and assesses adherence with NICE guidance.

Aims

The aim of this study was to compare the cost-effectiveness of surgical fixation with Kirschner (K-)wire ersus moulded casting after manipulation of a fracture of the distal radius in an operating theatre setting.

Aims

The aim of this trial was to assess the cost-effectiveness of a soft bandage and immediate discharge, compared with rigid immobilization, in children aged four to 15 years with a torus fracture of the distal radius.

Aims

Orthopaedic surgery requires grafts with sufficient mechanical strength. For this purpose, decellularized tissue is an available option that lacks the complications of autologous tissue. However, it is not widely used in orthopaedic surgeries. This study investigated clinical trials of the use of decellularized tissue grafts in orthopaedic surgery.

Aims

Conflicting clinical results are reported for the ATTUNE Total Knee Arthroplasty (TKA). This randomized controlled trial (RCT) evaluated five-year follow-up results comparing cemented ATTUNE and PFC-Sigma cruciate retaining TKAs, analyzing component migration as measured by radiostereometric analysis (RSA), clinical outcomes, patient-reported outcome measures (PROMs), and radiological outcomes.

We reviewed 21 patients with 22 ruptures of the extensor pollicis longus at a mean of 5.3 years after transfer of the extensor indicis proprius tendon. Of these, 19 with 21 transfers described the result as good, and two as fair. The mean deficit of extension between the operated and unoperated thumbs was 1.4 cm, and the mean flexion deficit 0.6 cm. Pressure gauge measurements showed that the strength of the transfer was 51% of that of the uninjured extensor. The two fair results had an extensor lag of over 1.5 cm. Independent extension of the index was maintained in all patients, none having a discernible lag, but the strength of index extension was reduced to 49% of that of the normal finger. There was no evidence of functional loss. Extensor indicis proprius transfer for rupture of the extensor pollicis longus tendon is a simple and reliable procedure with few complications. It gives satisfactory long-term extension of the thumb

Aims

Both anatomical and reverse total shoulder arthroplasty (aTSA and rTSA) provide functional improvements. A reported benefit of aTSA is better range of motion (ROM). However, it is not clear which procedure provides better outcomes in patients with limited foward elevation (FE). The aim of this study was to compare the outcome of aTSA and rTSA in patients with glenohumeral osteoarthritis (OA), an intact rotator cuff, and limited FE.

1. A large proportion of fractures were poorly reduced in this series either because the method used was inadequate or because it was inexpertly applied. At first it was thought that immobilisation in plaster gave adequate fixation but it was impossible to be certain that the reduction was not sometimes lost in the interval between manipulation and the check radiograph taken immediately after plaster had been applied. This suggested that in some cases fixation might be lost early although late redisplacement was not seen. 2. The late subjective results in patients with unreduced fractures were good, but there was some loss of thumb mobility partly due to varus deformity of the metacarpal bone and partly due to incomplete compensation for generalised stiffness in and around the joint. 3. Since loss of movement caused little disability and joint involvement rarely produced symptoms due to osteoarthritis, it seems doubtful whether the use of complex methods of treatment is justifiable. 4. Women seem to be predisposed to painful symptoms at the carpo-metacarpal joint of the thumb whether they occur after fracture or in association with non-traumatic osteoarthritis of the joint

Simultaneous paralysis of the ulnar, median and radial nerves is seen in about 1% of hands with nerve involvement in Hansen's disease. Forty such cases were treated between 1955 and 1976; 35 of these have been followed up. In two hands there was a high radial, median and ulnar palsy and these left no scope for reconstruction. The other 33 cases which underwent two-stage reconstructive surgery are presented here. The first stage consisted of restoring active extension of the wrist, fingers and thumb: for this purpose the ideal muscles for transfer are pronator teres, flexor carpi radialis and palmaris longus respectively, and muscle power exceeding Grade 3 (on the MRC classification) was achieved in 89%, 96%, and 100% of these individual transfers. Arthrodesis of the wrist is not recommended when suitable muscles are available for transfer. The second stage of reconstruction attempts to restore intrinsic function of the fingers and opposition of the thumb; the sublimis is ideal for both purposes and satisfactory restoration of function was achieved in 89% and 85% of cases respectively. Ten of the 18 hands in which all five tendons were transferred had good or excellent results

Aims

The aim of this study was to compare the cost-effectiveness of cemented hemiarthroplasty (HA) versus hydroxyapatite-coated uncemented HA for the treatment of displaced intracapsular hip fractures in older adults.

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 interphalangeal joint stabilisation and wound healing. We report a reliable clinical method for differentiating between the activity of extensor carpi radialis longus and brevis and describe a successful new split flexor pollicis longus tenodesis for stabilising the thumb interphalangeal joint. Bilateral simultaneous surgery gave generally better results than did unilateral surgery

Aims

To identify the responsiveness, minimal clinically important difference (MCID), minimal clinical important change (MIC), and patient-acceptable symptom state (PASS) thresholds in the 36-item Short Form Health Survey questionnaire (SF-36) (v2) for each of the eight dimensions and the total score following total knee arthroplasty (TKA).

Aims

Giant cell tumour of bone (GCTB) treatment changed since the introduction of denosumab from purely surgical towards a multidisciplinary approach, with recent concerns of higher recurrence rates after denosumab. We evaluated oncological, surgical, and functional outcomes for distal radius GCTB, with a critically appraised systematic literature review.

We compared the bulking and tensile strength of the Pennington modified Kessler, Cruciate and the Savage repairs in an ex vivo model. A total of 60 porcine tendons were randomised to three groups, half repaired using a core suture alone and the remainder employing a core and peripheral technique. The tendons were distracted to failure. The force required to produce a 3 mm gap, the ultimate strength, the mode of failure and bulking for each repair were assessed. We found that there was a significant increase in strength without an increase in bulk as the number of strands increased. The Cruciate repair was significantly more likely to fail by suture pullout than the Pennington modified Kessler or Savage repairs. We advise the use of the Savage repair, especially in the thumb, and a Cruciate when a Savage is not possible. The Pennington modified Kessler repair should be reserved for multiple tendon injuries

Aims

It remains difficult to diagnose early postoperative periprosthetic joint infection (PJI) following total knee arthroplasty (TKA). We aimed to validate the optimal cutoff values of ESR, CRP, and synovial fluid analysis for detecting early postoperative PJI in a large series of primary TKAs.
