A randomised prospective study has already demonstrated that at 1-year follow-up, palmaris longus interposition or flexor carpi radialis (FCR) ligament reconstruction and tendon interposition do not improve the outcome of trapeziectomy for the treatment of painful osteoarthritis of the trapeziometacarpal joint. This study consisted of 183 thumbs in 162 women. 114 of the 183 thumbs have now completed their 5-year follow-up and this study reports their results.Background
Aims
Trapeziectomy with ligament reconstruction and tendon interposition (LRTI) with the flexor carpi radialis (FCR) tendon is one of the most common procedures for the treatment of thumb carpometacarpal (CMC) arthritis. An alternative method involves trapeziectomy alone (TA). The trapeziectomy with LRTI procedure was developed to theoretically improve biomechanical strength and hand function when compared to TA, which leaves an anatomical void proximal to the first metacarpal. The LRTI procedure takes longer to perform and includes an autologous tendon graft. The goal of this retrospective cohort study was to evaluate the clinical outcomes of trapeziectomy with or without LRTI at a minimum follow-up of 1 year. A total of 43 adult patients who had underwent a total of 58 (TA=36, LRTI=22) surgical procedures for CMC arthritis participated in the study. This single surgeon retrospective cohort study sampled patients who underwent CMC arthroplasty with either TA or LRTI techniques between 2008 and 2020 with a minimum time of 1 year post-operatively. The patients were evaluated subjectively (The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire) and objectively (hand/thumb strength, pre/post-operative hand radiographs). Both the TA and LRTI procedures provided good pain relief, motion, strength, and stability without any severe complications. There was no statistically significant difference in hand or thumb strength between the two groups. Radiography showed that compared to the preoperative status, the
The scaphotrapeziotrapezoid (STT) joint is one of the key link joints between the proximal and the distal carpal rows. We assessed the relationship between the scaphotrapezium (STm) andscaphotrapezoid (STd) joints using computerised tomographyand hypothesised the ratio of STm is =/< STd joint due to which, the possibility of failure of trapeziectomy due to metacarpal collapse is insignificant. We reviewed CT scans of wrist joints of 113 eligible patientsfrom our wrist database between 2009 and 2014 for our study. 31 patients were randomised for interobserver correlation. Reformatted multi-planar sequences were analysed. The ratio of theSTm: STdin sagittal and coronal measurementswas evaluated. Interobserver variations were assessed using the Pearson coefficient. The sex distribution included 68 males and 29 females, 49 left and 64 right wrists. The STm area was larger in 86 (76%) as compared to STd in 27(24%). Average
Thumb Carpometacarpal (CMC) arthritis is a common pathology of the hand. Surgical treatment with thumb reconstruction is well described. Retrospective outcomes have been described for multiple techniques, suggesting patient satisfaction with multiple different techniques. The Thompson technique uses a slip of Abductor Pollicis Longus for suspension and interposition as well as excision of the
Trapeziometacarpal arthritis is a common condition, causing symptoms in up to ten percent of women and one percent of men¹. LRTI is the most commonly used surgical technique for this condition however, long-term studies have shown persistent weakness of pinch strength² after surgery. The Ascension® PyroDisk is a pyrocarbon disk shaped implant designed to articulate against the
Scaphoid fractures are a common injury accounting for more than 58% of all carpal bone fractures(1,2). Biomechanical studies have suggested that scaphoid mal-union may lead to altered carpal contact mechanics causing decreased motion, pain and arthritis(1,2). The severity of mal-union required to cause deleterious effects has yet to be established. This limits the ability to define surgical indications or impacts on prevention of posttraumatic arthritis. Computed tomography has been shown to be a useful in determining the 3D implications of altered bony alignment on the joint contact mechanics of surrounding joints. The objective of this study was to report mid-term follow-up image-based outcomes of patients with scaphoid mal-unions to determine the extent to which arthritic changes and decreased joint space is present after a minimum of 4 years following fracture. Participants (n=14) who had previously presented with a mal-united scaphoid fracture (indicated by a Height:Length Ratio >0.6) between November 2005 and November 2013 were identified and contacted. A short-arm thumb spica case was used to treat X patients and X required surgical management. Baseline and follow-up CT images, were performed with the wrist in radial deviation and positioned such that the long axis of the scaphoid was perpendicular to the axis of the scanner. Three-dimensional inter-bone distance (joint space), a measure of joint congruency and 3D alignment, was quantified from reconstructed CT bone models of the distal radius, scaphoid, lunate, capitate,
Introduction. The first carpometacarpal (CMC) joint is the second most common joint of the hand affected by degenerative osteoarthritis (OA). 1. Laxity of ligamentous stabilizers that attach the first metacarpal bone (MC1) and the
Purpose of the study:. Improved technology, increasing experience and techniques warrant an analysis of cost effective ways of medical management in general and shoulder decompression specifically. The question raised was whether a less invasive technique is necessarily the most cost effective way or merely the surgeons' preferred technique. This is a retrospective study of patients at Tertiary Academic Institution who underwent an open or arthroscopic shoulder decompression in the past 3 years. The aim of the study is to do a cost analysis of shoulder surgery as private health care (medical aid) is demanding more cost effective procedures and we have limited funds in the Government setting. Methods:. We focused on the following: the surgeon; the procedure; operating time; inpatient time; intraoperative block; physiotherapy costs, time off work and the cost of instrumentation used. Patients had to comply with specific inclusion and exclusion criteria. Inclusion: All patients that had shoulder decompression surgery in the past three years by a qualified orthopaedic surgeon; Exclusion: sepsis, tumours, rotator cuff tears, conversion of an arthroscopic procedure to an open procedure intraoperatively, inadequate notes, multiple surgical procedure under the same anaesthetic (e.g. scope with a
Background. The trapeziometacorpal joint (TMJ) of the thumb is a common site of primary osteoarthritis. Pain, crepitis and instability secondary to subluxation are common symptoms associated with TMJ arthritis. Conservative therapy help to control symptoms however with time, many patients progress with pain, deformity and functional limitation. The goals of operative intervention are to restore stability and strength, decrease pain and to provide a functional range of motion. Francobal-prosthesis may fulfil these criterions. Technique. We implanted the prosthesis through a dorso-radial straight longitudinal or slightly curved skin incision. A dorsal capsulotomy is performed and at this step adduction deformity should be addressed. An osteotomy of the proximal surface of the first metacarpal is made perpendicular to the long axis of the medullary cavity followed by reaming of the medullary cavity and then a trial fit. This is followed by preparation of the
Background. In suspected scaphoid fracture the initial scaphoid series plain radiographs are 84-94% sensitive for scaphoid fractures. Patients are immobilised awaiting diagnosis. Unnecessary lengthy immobilisation leads to lost productivity and may leave the wrist stiff. Early accurate diagnosis would improve patient management. Although Magnetic Resonance Imaging (MRI) has come to be regarded as the gold standard in identifying occult scaphoid injury, recent evidence suggests Computer Tomography (CT) to be more accurate in identifying scaphoid cortical fracture. Additionally CT and USS are frequently a more available resource than MRI. We hypothesised that 16 slice CT is superior to high spatial resolution Ultrasonography (USS) in the diagnosis of radiograph negative suspected cortical scaphoid fracture and that a 5 point clinical examination will help to identify patients most likely to have sustained a fracture within this group. Methods. 100 patients with two negative scaphoid series and at least two out of five established clinical signs of scaphoid injury (anatomical snuffbox tenderness (AST), scaphoid tubercle tenderness (STT), effusion, pain on circumduction and pain on axial loading) were prospectively investigated with CT and USS. MRI was arranged for patient with persistent symptoms but negative CT/USS. Results. CT demonstrated 8 scaphoid fractures. 17 other fractures (1st metacarpal,
