Background. Traditional teaching recommends against arthroplasty in the index finger, due to concerns over failure with pinch stress, and prefers arthrodesis is for its stability. We aim to allay these fears and present the results of our series of index finger silastic PIPJ arthroplasties. Methods: Between 2007 & 2018 48 silastic index finger PIPJ arthroplasties were undertaken in 37 patients at our Hand Unit. All were performed under local anaesthetic ring block. Eleven patients underwent PIPJ arthroplasty in both Index fingers. Thirty-five women and two men made up the cohort with a mean age of 69 years. A retrospective analysis of all patients has been undertaken to determine the clinical results including patient satisfaction, grip and pinch strength and reoperation rates. Mean follow up was 5.1 years. Results. Six index fingers developed ulnar deviation greater than 10 degrees and there were five reoperations (10.2%). There was an excellent arc of movement of mean 44 degrees with high patient satisfaction and functional scores (mean VAS pain score 1.1, Quickdash 34, PEM 44). 90% of patients would undergo the procedure again and no patient would prefer a fusion. Conclusions: Silastic Interposition arthroplasty of the PIPJ of the Index finger is a durable procedure with excellent clinical outcomes. Our large study refutes the established technique of arthrodesis for Index finger OA, with low incidence of ulnar deviation and excellent patient satisfaction

Author’s experience in surgical treatment of aplasia of the thumb according to the Buck-Gramcko procedure introduced by this author in 1971 is reported. Inidcation of the pollicization of the index finger according to Buck-Gramcko is aplasia of the thumb in the 3rd, 4th and 5th stages (Blauth’s classification). The surgical technique is particulary complex because of knowledge of microsurgery and soft-tissue reconstruction necessary. The different surgical phases may be schematically divided into a cutaneous stage which calls for the reconstruction of the web space, a vacular stage, a skeletal stage in which the reduction of the trapezium radial I metacarpal is reduced and a miotendinous stage. Surgery is carried out on patients of at least one year of age as it is necessary their cardial-pulmonary system be adequately mature, development of the endostal circle, thicker vascular walls and a suitably developed bimanual grasp, as well. The revision of these cases treated is especially significant because an average follow-up of the 17 years puts in good light the functionality of the hand, both from the points of view of strength and movement (Percival’s classification). After a revision of the case studies with a long term f.-u. we may affirm that the pollicization of the index finger according Buck-Gramcko, to achieve the development of the first finger in opposition, is the best-choice surgery in the reconstruction of the aplasial thumb and owes its effectiveness to the association of microsurgical techniques for preparing an island pedicle composite-tissue flap to the cardinal principles of articular reconstruction and of tendon transfers

Aims: To describe a new & safe technique of gradual distraction for pollicisation of index finger, to which the blood supply is doubtful. This procedure was used in cases where conventional methods of pollicisation are not possible or are risky. Methods: This technique has been utilised in 5 cases (2 traumatic loss of thumb at carpo-metacarpal joint, and 3 cases of absence of thumb associated with radial club hand). The age group was 3–18 years. The procedure consisted of first stage, a webplasty between second & third fingers, osteotomy of the base of second metacarpal and gradual wide abduction of the index finger by distraction. In second stage, the second metacarpal is recessed and rotated, to the position of thumb. At third stage, tendon transfer may be needed for securing the forceful opposition. Results: In all operated 5 cases, desired position of the thumb was obtained along with good function. Conclusion: Gradual distraction for pollicisation may be used in cases where the blood supply of index finger is not based on known specific blood vessel but depends on collateral blood supply. Conventional methods cannot be used or are risky. This technique provides a safe and economical alternative for reconstruction of the thumb, which is a new addition to the armamentarium in thumb reconstruction

Background. Bouchard -arthrose is often familial and affect predominantly females. It starts as acute inflammation of the soft tissue and with time may progress to severe deformity and limitation of movement. In the early phases one of the most commen operation in the management is the synovialectomy. In late stages with severe destruction and deformity of the joint arthrodesis can be carried out. However, arthrodesis may lead to severe loss of function. One of the most commonly and world wide used prothesis to maintain movement is the Swanson –spacer. Material and Methods. 20 Swanson-implants in 14 patients (12 female,2 male) were evaluated subjectively and objectively using PIJA-score (Interphalangeal-joint –score) and Dash –score. The follow period was 4.6 years (range 1-11 years). Results. The IPJA-score ranged 8-14 points (median 11.8) and the median Dash- score was 28 points. Improvement of pain was oberserved in 90% of the cases. Flexion more than 30° in 85% and full extention in 75%. Ulnar deviation was noted in 7 patients (35%), mostly of the index finger. Fracture of the prothesis occurred only in 1 case. No loosening was observed radiologically. Discussion. Swansin prothesis is good alternative to arthrodesis and be restricted only in cases where the musculotendinous structures are intact. In cases where the index finger is affected, arthrodesis is preferred

Clinician expectation and anatomical studies suggest that the distribution of sensory dysfunction in carpal tunnel syndrome (CTS) should be confined to the thumb, index, middle and half of the ring fingers. We mapped the distribution of disturbance to evaluate the accuracy of these assumptions. We evaluated 64 wrists in 64 patients with nerve conduction study confirmed CTS. Each patient filled out a Katz hand diagram and we collated the distribution of pain and non-painful (tingling, numbness & decreased sensation) sensory disturbance. Frequency of reporting was analysed; dividing symptoms into thenar and hypo-thenar eminence, distal palm, each digit, posterior hand and forearm. Non-painful sensory disturbance occurred in all patients. The index finger was the most common location (94%) followed by the middle finger (91%), the distal palm (84%), the ring finger (72%), the thumb (69%), the thenar eminence (63%), the little finger (39%), the dorsal hand (31%), the hypothenar eminence (25%) and the forearm (13%). Pain was less common, reported in 59% of cases. Pain occurred most frequently over the wrist crease (33%) followed by thenar eminence (27%), the forearm (20%), the middle finger (23%), the index finger (22%), the ring finger (19%), the distal palm (16%), the thumb (14%), the dorsal hand (11%), the little finger (11%) and least frequently the hypothenar eminence (6%). In CTS sensory disturbance occurs most frequently in the median nerve distribution; however it occurs almost as often elsewhere. An atypical distribution of symptoms should not discourage diagnosis of CTS

Purpose. To analyse the early results of unconstrained pyrocarbon joint replacements in patients with osteo-arthritis of the metacarpo-phalangeal joints. Background. Silicone arthroplasty, as introduced by Swanson in 1962 has remained the most popular procedure to treat arthritis of the metacarpo-phalangeal (MCP) joints. However, despite providing good pain relief, they have shown to demonstrate breakage rates up to 82% at 5 years. This is of great concern in the osteoarthritis (OA) patient group, who tend to be younger and have higher functional demands compared to their rheumatoid counterparts. The newer unconstrained pyrolytic carbon MCP joint prostheses may therefore be more suitable in OA patients whose soft tissue constraints are intact and whose hand function is strong. This study is the first to analyse the results of this implant in a cohort of OA patients only, with prospective data. Methods. 19 primary pyrocarbon metacarpo-phalangeal joint replacements, in 11 patients (5 men and 6 women) were reviewed, with prospective data collection. The diagnosis was primary osteoarthritis in all patients. The mean age at operation was 66.4 years (range 55–82 years). 2 patients underwent concomitant trapiezectomy and one underwent DIPJ fusion. All patients were right hand dominant −75% underwent surgery in their dominant hand. Eleven of the nineteen joints were performed in the index finger, with the remainder in the middle finger. Mean follow up is 22.1 months (range 11–37). Results. At the 3 month post-operative hand therapy assessment, the arc of motion had improved from a mean of 32 degrees to 45 degrees and flexion had improved from a mean of 51 degrees to 66 degrees. Grip strength improved from a mean 20 to 27Kg. DASH scores significantly improved from a mean of 40 to 10 (p=0.01). All patients were satisfied with their outcomes and would have the surgery again. Pre-operative radiographs demonstrated joint narrowing in all patients but no evidence of heterotopic ossification, cystic change or erosions. Post-operatively, there has been no radiographic evidence of joint dislocation, resorption stress-shielding, loosening, migration or heterotopic ossification. There were three intra-operative complications of phalangeal fractures that were immediately treated with a cerclage wire. In one patient there has been a fracture of the proximal phalangeal implant at 14 months which was asymptomatic. One patient has required revision for mal-rotation of the implant leading to loss of index finger supination. Conclusion. Our results demonstrate excellent early results of pyrocarbon MCP joint arthroplasty in OA patients

Objective. We explanted NeuFlex metacarpophalangeal (MP) joint prostheses to identify common features, such as position of fracture, and thus better understand the reasons for implant failure. Methods. Explanted NeuFlex MP joint prostheses were retrieved as part of an-ongoing implant retrieval programme. Following revision MP joint surgery the implants were cleaned and sent for assessment. Ethical advice was sought but not required. The explants were photographed. The position of fracture, if any, was noted. Patient demographics were recorded. Results. Thirty NeuFlex MP explants were available. Seven (23%) were not fractured. Eleven explants (37%) had fractured at the hinge; nine (30%) had fractured at the junction of the distal stem and hinge; and three (10%) had fractured at both the hinge and distal stem. NeuFlex MP joint explants ranged in size from 0 to 40. Smaller sizes were retrieved from smaller fingers; larger implants came from the middle and index fingers. The age at revision ranged from 43 to 81 (median 58) years. Time in vivo ranged from 6 to 120 (median 58.5) months. All but two implants were obtained from rheumatoid joints, the remainder had osteoarthritis. Discolouration of some explants had occurred; other explants appeared to show no colour change. Conclusions. This is the first report of the position of fracture of NeuFlex explants. It is also the largest report of silicone arthroplasty explants. The majority (77%) had fractured. Nine (30%) NeuFlex explants had fractured at the junction of the distal stem and hinge; the typical position seen with Swanson and Sutter/Avanta MP joint explants. Eleven (37%) fractured across the hinge; this has not previously been reported although has been seen in in vitro testing. The hinge is thinner than the hinge-stem junction so may be at risk of more rapid failure, however the median time in vivo for hinge fractures was 63 months as opposed to 54 months for fractures at the distal stem. Intriguingly, 3 (10%) NeuFlex explants suffered fractures both at the hinge and at the junction of the distal stem and hinge which has also never been reported previously. Fracture at the junction of the distal stem and hinge shows the importance of subluxing forces in rheumatoid MP joints and therefore suggests these need to be mitigated as much as possible. Fracture across the hinge could indicate this as a position which could be increased in thickness, to increase the time taken to fracture, although there may be a concomitant increase in stiffness of the implant. With improved designs, patients might suffer fewer or later failures. The latest Norwegian Arthroplasty Registry report shows that revision MP joint arthroplasties accounted for 42% of all MP joint replacement operations in 2015. Therefore, this is an important area where opportunities exist to reduce revision rates

Aggressive digital papillary adenocarcinoma (ADPACa) is a rare skin adnexal tumour, which has a predilection for the digits. We report a case with this tumour in a 51 year old insulin dependent diabetic man, who presented as a paronychia of right index finger. After histopathological confirmation as an ADPACa partial amputation was performed. This case emphasizes the presentation of this tumour as a simple nail bed infection occasionally

Objective. Surgical treatment of trigger finger is usually performed as an outpatient surgery under local anesthesia n this study we present our results of surgical treatment of trigger finger performed with an ophthalmic knife which is less invasive for patient and easer for surgeon. Material and Method. 19 gauges microvitreoretinal ophthalmic knifes have a rhombus like edge with both sharp sides. The length of the knife's cutting side is 3 mm at each side. There were 40 women and 10 men with a mean age of 51.7 ± 5.7 (min: 40 max: 62). The thumb was involved in 32, the index finger in 10, and the middle in 8 patients. The procedure can be performed as an outpatient surgery under local anesthesia. The surface landmarks of the proximal and distal edges of the A1 pulley are marked on the skin. Percutaneous placement of a 25-gauge needle 5mm proximal to the PDC marked the distal extent of the release. The duration of procedure was under five minutes. Clinical examination was repeated on the postoperative 3rd day, 10th day and patients were re-examined or spoken to by telephone at a mean follow-up of 6.4 months. Results. Of the 50 digits treated, there was complete resolution of symptoms in 45 digits (90%). 3 thumbs had residual grade 1–2 triggering at the second follow up. 2 patients with locked trigger thumbs had persistent, despite relief of the triggering. Discussion. In this study we noted that percutaneous release with a 19 gauges MVR ophthalmic knife is a safe, cheap, quick, less scaring and comfortable treatment

Introduction. Various methods to manage medial tibial defects in primary total knee arthroplasty (TKA) have been described. According to Vail TP, metal augmentation is usually indicated for defect depth of >10 mm of the medial tibial plateau. The outcomes of metal augmentation have been described as excellent. Nevertheless, we believe that it is mandatory to preserve as much of the bone as possible for future revision surgeries. Therefore, we performed autologous impaction bone grafting even for large bone defects (defect depth of ≥10 mm) in primary TKA. The objectives of this study are to describe our bone grafting technique in detail and to assess the radiological outcomes of the grafted bone. Methods. Between 2003 and 2011, 26 TKAs with autologous impaction bone grafting for ≥10 mm medial tibial defects were performed. The preoperative diagnoses were osteoarthritis in 17 knees, rheumatoid arthritis in 2 knees, osteonecrosis of the medial tibial condyle in 6 knees, and Charcot's joint in 1 knee. The average mediolateral width and depth of the medial tibial defects, measured after the horizontal osteotomy of the tibial articular surface, were 17.8 mm (range, 10–25 mm) and 12.0 mm (range, 10–23 mm), respectively. The average patient age at surgery was 73.2 years (range, 56–85 years). The patients were followed up for an average of 55 months (range 27–109 months). Bone grafting technique: Multiple drill holes (white arrow) were made on the floor of the defect (A) and a morselized cancellous bone was impacted using the grip end of a metal hammer (white asterisk) and firm manual pressure to fill the defect. Thus, the firm impaction prevented bone cement from entering the space between the graft and the tibial host bed. An assistant's index finger (black asterisk) was used as a bank (B). The tibial component was fixed on the grafted bone (white asterisk) with bone cement (C). Internal fixation devices were not required, and stem extension was used in only Charcot's joint (defect depth=23 mm). Aftertreatment was the same as that for the usual TKAs without bone defects. Results. In terms of clinical outcomes, no patient showed disturbances in walking ability at final follow-up. The average knee flexion angle was 114° (range, 95°–130°). The grafted bone was kept at the grafted area on the radiograms throughout the follow-up period. No absorption or collapse of the grafted bone was observed on the radiograms at the final follow-up. Usually, the grafted bone showed osteosclerotic changes around 2–3 months after TKA. Then, the osteosclerosis became weakened and the bony trabeculae could be detected in the grafted area. Finally, the grafted bone completely incorporated into the host bone in all knees with evidence of bony trabeculae crossing the interface by up to 1 year after surgery. The margin of the grafted area resembled bony cortex in 19 TKAs (73.1%). Conclusions. Our technique is easy, economic, and reproducible. It is an acceptable alternative to metal augmentation for large medial tibial defects in primary TKA

This study measured the three bony axes usually used for femoral component rotation in total knee arthroplasty and compared the accuracy and repeatability of different measurement techniques. Fresh cadaveric limbs (n=6) were used. Three observers (student, trainee and consultant) identified the posterior condylar (PCA), anteroposterior (AP) and the transepicondylar (TEA) axes, using a computer navigation system to record measurements. The AP axis was measured before and after being identified with an ink line. The TEA was measured by palpation of the epicondyles both before and after an incision was made in the medial and lateral gutters at the level of the epicondyles, allowing the index finger to be passed behind the gutters. In addition the true TEA was identified after dissection of all the soft tissues. Each measurement was repeated three times. For all axes and each observer the repeatability coefficient was calculated. The identification of the PCA was the most reliable (repeatability coefficient: 1.1°) followed by the AP after drawing the ink line (4.5°) then the AP before (5.7°) and lastly the TEA (12.3°) which showed no improvement with the incisions (13.0°). In general the inter-observer variability for each axis was small (average 3.3°, range 0.4° to 6°), being best for the consultant and worst for the student. In comparison to the true TEA, the recorded TEA and AP axis averaged within 1.5° whilst the PCA was consistently 2.8° or more internally rotated. This study echoed previous studies in demonstrating that palpating the PCA intra-operatively is highly precise but was prone to errors in representing the true TEA if there was asymmetrical condylar erosion. The TEA was highly variable irrespective of observer ability and experience. The line perpendicular line to the AP axis most closely paralleled the true TEA when measured after being identified with an ink line

The authors studied the characteristics that would be desirable for a metacarpo-phalangeal joint prosthesis to be used in patients with rheumatoid disease. In these patients the severe destruction of the capsulo-ligamentous structures of the joint often makes prosthetic substitution dissatisfactory, particularly for the index finger. Such a prosthesis should be restricted in its range of motion, actually abolishing any ulnar deviation. Axial rotaion should be coupled to flexion-extension and radial deviation to gain an adequate stress dissipation at the interface. Both distal and proximal stems should be conical, for the best possible distribution of shear stresses at the interface. A flattening surface should accommodate properly the externsor apparatus without interfering with it. The greatest possible congruence should be required for the articulated components. The rationale of such a design for a rheumatoid patient lies in the fact rheumatoid arthritis is the most important indication for a metacarpo-phalangeal joint arthroplasty, due to the highly incapacitating condition that may ensue. Then, despite limitations required by the proposed design, an improvement in the functional ability of the rheumatoid patient will be obtained

Firecracker injuries to the hands can cause permanent functional loss and disfigurement. We assessed the injuries and treatment of 16 men, three women, five boys and two girls injured around New Year’s Eve between 1999 and 2004. In 16 of the adult patients, who included a typist and a teacher, it was necessary to amputate one or more digits. Four patients lost both the thumb and the index finger, four lost the thumb and the rest lost other digits. Only soft tissue injuries were sustained by 10 of the 26 patients. Twenty patients (77%) benefited from initial debridement and primary closure alone, but the other six needed more than one procedure, and half of this group developed sepsis. The psychological impact was important in adults. Associated injuries included the loss of an eye in one patient, facial lacerations in 10 and a perforated eardrum. The mean hospital stay was 5 days. Public education and legislative reform may help prevent these unnecessary injuries

Introduction and Objectives: One of the techniques used to improve function in thumb hypoplasia is Pollicisation, this is used in thumb hypoplasia Blauth grade 3b, 4 and 5. The objectives of this technique are: to modify the position of the index finger, its length and tendon insertions, while maintaining original circulation and sensitivity; so as to achieve a thumb capable of responding to a medium-high functional demand. We assessed the results obtained using the Buck-Gramcko technique in the 12 de Octubre Hospital. Materials and Methods: We retrospectively analyzed 10 pollicisations performed between 1986–2008, 3 patients had bilateral hypoplasia and another two suffered from polymalformation syndrome. Mean age at surgery was 27 months, and the minimum postoperative follow-up was 10 months. An objective assessment of results was based on: morphology, sensitivity, intrinsic-extrinsic mobility and strength. During analysis of the results we also took into account the subjective assessment of parents and children. Results: In all cases the sensitivity of the new thumb was satisfactory, extrinsic mobility was good, and intrinsic mobility, although less in the cases of bilateral hypoplasia and polymalformation syndrome, was satisfactory. Subjective assessment showed a high functional integration of the new thumb, and a high degree of satisfaction on the part of parents and children. Discussion and Conclusions: Pollicisation is an effective technique that improves hand function in patients with thumb hypoplasia as from Blauth stage 3b

Introduction: In 1979 Linburg and Comstock described anomalous tendon slips between flexor pollicus longus and the flexor digitorum profundus in 31% of individuals (Linburg, Comstock; J Hand surg 1997, Jan). The purpose of this study is to find out the incidence of Linburg-Comstock Syndrome in the British population. Methods: A clinical examination of the hands of healthy volunteers, including office workers and medical professionals was carried out. It was determined if flexion of the thumb causes concomitant flexion of index or/and middle finger. Additionally, pain on passive extension of the fingers was also documented. Summary of Results: 70 volunteers were included, the test for Linburg-Comstock syndrome was positive in 55% of people who had concomitant flexion of the fingers with the thumb and pain in the wrist with passive extension. In 70% of people just concomitant finger flexion was seen. In 10 cadaveric dissections no connecting tendon slips were found but one fibrinous connection between FPL and FDP was noted. Conclusion: Our study shows that the incidence of Linburg –Comstock Syndrome is much higher than previously thought based on the clinical examination. However cadaveric dissections did not confirm a distinct structural connection except in one case where there was a fibrinous connection. It is likely that at least in some cases it is a acquired anomaly in response to repeated use/overuse of thumb and index fingers

Suture anchors have changed the practice of repair of tendons in modern Orthopaedics. The purpose of the study was to identify the ideal suture anchor length for anchoring flexor digitorum profundus tendon to the distal phalanx. We dissected 395 distal phalanges from 80 embalmed hands. Phalanges from two little fingers and three thumbs were damaged, hence were excluded from the study. We measured the Anteroposterior and Lateral dimensions at three fixed points on the distal phalanges of all 395 fingers using a Vernier’s Callipers with 0.1mm accuracy. The mean value of the Anteroposterior width of the distal phalanx at the insertion of the FDP was found to be 3.4mm for the little finger; 3.9mm for the ring finger; 4.3mm for the middle finger; 4.0mm for the index finger and 5.0mm for the thumb respectively. The commonly available anchors and drill bits were found to be too long when used for anchoring the flexor digitorum profundus tendon in certain distal phalanges. Our findings may be a reason for poor outcome of FDP repair to distal phalanx using suture anchors. New designs for tissue anchors for distal phalanges may be necessary

Introduction: It is said that God gave us paired bilateral anatomical structures so that the trauma surgeon can compare the injured side with its uninjured counterpart. The axial rotational alignment of fingers, when disrupted by injury, may lead to scissoring. During examination, comparison is made between the rotational alignment of injured and uninjured fingers. This assumes that the rotational alignment of the fingers is symmetrical. A study was performed to ascertain normal rotational alignment, and establish whether this assumption is valid. Materials and Methods: Standardised digital images were taken with fingers in extension. These were analysed using the angle-measuring tool on Adobe Photoshop software. The rotational angle used was that between a line joining the radial and ulnar borders of the nail plate, and the horizontal. Results: Mean angles of rotation were 13° for the index finger, 10° for the middle, 5° for the ring and 12° for the little. Differences in the angle for ring and little fingers between the sides were not significant; these fingers are symmetrical. Index and middle fingers demonstrated statistically significant asymmetry of 2.6° (SD +/− 4.2°). Discussion: Previous work has sought to quantify rotational alignment in cadavers or using wire markers and fluoroscopy. A new method, using digital photography and image analysis is described. We determined mean angles, showing symmetry of the ring and little but asymmetry of index and middle. Previous work has suggested that up to 10° of rotation can be tolerated. With only 2.6° of difference, clinical comparison of sides remains appropriate

The aims of the study presented here were to compare the frequency of surgical glove perforation among major and minor orthopaedic surgical procedures and to determine the efficacy of use of double glove in these procedures. A prospective study was performed to assess the perforation rate of surgical gloves in 100 major (total hip and knee arthroplasty) and 100 minor (arthroscopy) orthopaedic procedures. Glove perforation rate, location of perforation, and time of operation were analysed. In 200 procedures, 1528 gloves were inspected; 622 inner gloves, 906 outer gloves were examined. All members of the surgical team wore double gloves in major and minor surgical procedures. The overall perforation rate was 242 out of 1528 gloves (15.8%), and 70 out of 200 operations (35%) (major versus minor surgical procedures, 21.6% versus 5.6%, p< 0.05, and 63% versus 11%, p< 0.001, respectively). For major procedures, 224 glove perforations were determined, of which 23 were in the inner glove and 201 in the outer glove. For minor procedures, 13 glove perforations were observed, and no perforation were found in the inner gloves used by the surgical team for minor procedures. The right thumbs and left index finger had more punctures than others. The mean operative time for major procedures was 76.5 ± 22.4 (range; 45 to 125) min while that for minor procedures was 29.5 ± 12.6 (range; 17 to 60) min (p< 0.001). Double gloving has proven to be an effective second barrier. We recommend the routine use of the double gloving method in major and minor orthopaedic procedures, because the double gloving method can significantly reduce the perforation of inner gloves

Objective. Destruction and deformity in both PIP and MP joints are not uncommon and cause sever disabilities. Arthroolasty of the MP joint combined with arthrodesis of the PIP joint are the usual choice for this condition. Some motion in ulnar digits provides great benefits for rheumatoid patients. We report implant arthroplasty of the PIP joint and also simultaneous replacement of PIP and MP joint in same finger. Material & Methods. Twenty-five joints in 15 patients underwent PIP arthroplasty either with silicone or surface replacement implant. Twelve PIP joints in 6 patients used Silicone implant (6 Swanson and 6 Avanta) alone and mean follow up was 42(6–84) months. New cementless surface implant (Self Locking Finger Joint, SLFJ) were developed and clinically used for about 3 years. Because of the stem design, SLFJ are able to use both PIP and MP joint simultaneously or combined with silicone implant. Four PIP joints in 3 patients used SLFJ alone and 6 patients underwent both PIP and MP joint with implant simultaneously. Combination of SLFJ PIP and silicone MP was 4 finger in 2 hand, SLFJ PIP and SLFJ MP was 3 finger in 2 hand, silicone PIP and SLFJ MP was 3 finger in 2 patients and silicone PIP and silicone MP was 1 finger. Mean follow up for SLFJ in either PIP or MP was 18(4–37) months. Results. Average arc of the PIP with silicone implant alone was 38(10–50 ° and SLFJ alone was 55(45–60) °. One PIP SLFJ dislocates immediate after surgery and was converted silicone later on. Of 7 SLFJ with combined PIP and MP arthroplasties, 2 PIP lost motion completely, one PIP move only 15°, 4 PIP move 75 °in average. Four silicone PIP combined with MP arthroplasties move 45°in average. One PIP SLFJ had breakage in stem legs, which believed to occur during interaction of stem insertion from both side of the basal phalanx, and was seen at immediate post op X-ray. There was one instability in index replaced with SLFJ for sever Swan neck deformity and no infection. Patient satisfaction for simultaneous replacement in PIP and MP joint were excellent except one whose age was 72. Discussion. Stability of the PIP joint in index finger is important for pinch and PIP motion of ring and little fingers are required for grip motion. Although arthrodesis of the PIP joint were performed more often and functional improvement usually obtained compared to pre-operative condition, ulnar 2 digits better to preserve some motion in the PIP joint as long as there is a possibility, and especially for the young patients. The results of the simultaneous replacement in PIP and MP joint seems discourage, however, when considering the severity of the deformities of this series, there is a good chance in the future. We will improve implant design and surgical technique as well as post-operative therapy, and continue to challenge the simultaneous replacement of PIP and MP joint

Aims

We aimed to establish the short- and long-term efficacy of corticosteroid injection for coccydynia, and to determine if betamethasone or triamcinolone has the best effect.

Methods

During 2009 to 2016, we treated 277 patients with chronic coccydynia with either one 6 mg betamethasone or one 20 mg triamcinolone cortisone injection. A susequent injection was given to 62 (26%) of the patients. All were reviewed three to four months after injection, and 241 replied to a questionnaire a mean of 36 months (12 to 88) after the last injection. No pain at the early review was considered early success. When the patient had not been subsequently operated on, and indicated on the questionnaire that they were either well or much better, it was considered a long-term success.
