Aims

Patients with a deformity of the hindfoot present a particular challenge when performing total knee arthroplasty (TKA). The literature contains little information about the relationship between TKA and hindfoot alignment. This systematic review aimed to determine from both clinical and radiological studies whether TKA would alter a preoperative hindfoot deformity and whether the outcome of TKA is affected by the presence of a postoperative hindfoot deformity.

A prospective study was made over a three-year period of 900 consecutive unilateral Colles' fractures. The radiographic features at the time of fracture, after reduction and one week later were measured and correlated with grip strength and range of movement at three years. The most significant radiographic feature to influence the outcome was the presence of shortening of the radius one week after reduction of the fracture. Persistent dorsal tilt, radiocarpal joint involvement and ulnar styloid fracture were each associated with reduced range of movement, but had no effect on grip strength. Extension of the fracture into the distal radio-ulnar joint was associated with reduced grip strength but had no effect on range of movement. Radial tilt of the radial fragment did not correlate with any aspect of the result after three years

Aims

To evaluate the rate of dislocation following dual mobility total hip arthroplasty (DM-THA) in patients with displaced femoral neck fractures, and to compare rates of dislocation, surgical-site infection, reoperation, and one-year mortality between DM-THA and bipolar hemiarthroplasty (BHA).

1. The results of thirty-nine operations for correction of drop-foot in thirty-three patients with leprosy are discussed. 2. The procedure used was circumtibial, subcutaneous, two-tailed, tendon-to-tendon transfer of the tibialis posterior to extensor hallucis longus and to extensor digitorum longus and peroneus tertius. The motor slips were inserted into the recipient tendons on the dorsum of the foot. 3. Analysis of the results showed some correlation between the angle of active dorsiflexion and the range ofactive movement ofthe ankle. The angle ofdorsiflexion seemed to determine the range of movement. 4. When contracture of the tendo calcaneus was present, simultaneous lengthening improved the angle of dorsiflexion more than the range of active movement. 5. The causes of failure were sepsis, failure of re-education and unrecognised tightness of the tendo calcaneus. 6. The advantages of the present procedure are mentioned

Aims

To analyze the potential role of synovial fluid peptidase activity as a measure of disease burden and predictive biomarker of progression in knee osteoarthritis (KOA).

We have treated 22 patients with an elbow contracture using a static progressive turnbuckle splint for a mean of 4.5 ± 1.8 months. All had failed to improve with supervised physiotherapy and splinting. The mean range of flexion before splintage was from 32 ± 10° to 108 ± 19° and afterwards from 26 ± 10° (p = 0.02) to 127 ± 12° (p = 0.0001). A total of 11 patients gained a ‘functional arc of movement,’ defined as at least 30° to 130°. In eight patients movement improved with turnbuckle splinting, but the functional arc was not achieved. Six of these were satisfied and did not wish to proceed with surgical treatment and two had release of the elbow contracture. In three patients movement did not improve with the use of the turnbuckle splint and one subsequently had surgical treatment. Our findings have shown that turnbuckle splinting is a safe and effective treatment which should be considered in patients whose established elbow contractures have failed to respond to conventional physiotherapy

Aims

The increase in prescription opioid misuse and dependence is now a public health crisis in the UK. It is recognized as a whole-person problem that involves both the medical and the psychosocial needs of patients. Analyzing aspects of pathophysiology, emotional health, and social wellbeing associated with persistent opioid use after injury may inform safe and effective alleviation of pain while minimizing risk of misuse or dependence. Our objectives were to investigate patient factors associated with opioid use two to four weeks and six to nine months after an upper limb fracture.

Aims

Perthes’ disease is a condition which leads to necrosis of the femoral head. It is most commonly reported in children aged four to nine years, with recent statistics suggesting it affects around five per 100,000 children in the UK. Current treatment for the condition aims to maintain the best possible environment for the disease process to run its natural course. Management typically includes physiotherapy with or without surgical intervention. Physiotherapy intervention often will include strengthening/stretching programmes, exercise/activity advice, and, in some centres, will include intervention, such as hydrotherapy. There is significant variation in care with no consensus on which treatment option is best. The importance of work in this area has been demonstrated by the British Society for Children’s Orthopaedic Surgery through the James Lind Alliance’s prioritization of work to determine/identify surgical versus non-surgical management of Perthes’ disease. It was identified as the fourth-highest priority for paediatric lower limb surgery research in 2018.

The PROSTALAC functional spacer is made of antibiotic-loaded acrylic cement but has a small metal-on-polythene articular surface. We have used it as an interim spacer in two-stage exchange arthroplasty for infected total knee replacement. PROSTALAC allows continuous rehabilitation between stages as it maintains good alignment and stability of the knee and a reasonable range of movement. It also helps to maintain the soft-tissue planes, which facilitates the second-stage procedure. We reviewed 45 consecutive patients, treated over a period of nine years. The mean follow-up was for 48 months (20 to 112). At final review, there was no evidence of infection in 41 patients (91%); only one had a recurrent infection with the same organism. There was improvement in the Hospital for Special Surgery knee score between stages and at final review. The range of movement was maintained between stages. Complications were primarily related to the extensor mechanism and stability of the knee between stages. Both of these problems decreased with refinement of the design of the implant. The rate of cure of the infection in our patients was similar to that using other methods. Movement of the knee does not appear to hinder control of infection

There is no consensus on the benefit of arthroscopically assisted reduction of the articular surface combined with fixation using a volar locking plate for the treatment of intra-articular distal radial fractures. In this study we compared the functional and radiographic outcomes of fluoroscopically and arthroscopically guided reduction of these fractures. Between February 2009 and May 2013, 74 patients with unilateral unstable intra-articular distal radial fractures were randomised equally into the two groups for treatment. The mean age of these 74 patients was 64 years (24 to 92). We compared functional outcomes including active range of movement of the wrist, grip strength and Disabilities of the Arm, Shoulder, and Hand scores at six and 48 weeks; and radiographic outcomes that included gap, step, radial inclination, volar angulation and ulnar variance. . There were no significant differences between the techniques with regard to functional outcomes or radiographic parameters. The mean gap and step in the fluoroscopic and arthroscopic groups were comparable at 0.9 mm (standard deviation. (sd). 0.7) and 0.7 mm (. sd. 0.7) and 0.6 mm (. sd. 0.6) and 0.4 mm (. sd. 0.5), respectively; p = 0.18 and p = 0.35). . Arthroscopic reduction conferred no advantage over conventional fluoroscopic guidance in achieving anatomical reduction of intra-articular distal radial fractures when using a volar locking plate.

Aims

Bone demonstrates good healing capacity, with a variety of strategies being utilized to enhance this healing. One potential strategy that has been suggested is the use of stem cells to accelerate healing.

Aims

A comprehensive classification for coronal lower limb alignment with predictive capabilities for knee balance would be beneficial in total knee arthroplasty (TKA). This paper describes the Coronal Plane Alignment of the Knee (CPAK) classification and examines its utility in preoperative soft tissue balance prediction, comparing kinematic alignment (KA) to mechanical alignment (MA).

Aims

Vertebrates have adapted to life on Earth and its constant gravitational field, which exerts load on the body and influences the structure and function of tissues. While the effects of microgravity on muscle and bone homeostasis are well described, with sarcopenia and osteoporosis observed in astronauts returning from space, the effects of shorter exposures to increased gravitational fields are less well characterized. We aimed to test how hypergravity affects early cartilage and skeletal development in a zebrafish model.

1. By the use of a device that allows movement of a human finger joint to take place uninfluenced by muscle activity, the coefficient of friction has been determined between living articular surfaces. 2. The force of friction rises as the range of movement is increased, because of the tension then developing in the ligaments and the soft tissues surrounding the joint. 3. Measurements have also been made of the forces of friction within the ankle joint of the dog and within four types of reciprocating bearings (plastic, oil-lubricated, "floating" and hydrostatic). 4. By altering the load borne by the joints and bearings it has been shown that joints resemble in their behaviour those bearings in which a film of fluid is maintained between the fixed and moving surfaces, rather than bearings depending wholly or in part on boundary lubrication. 5. It is suggested that joints normally owe their great freedom of movement to a special type of fluid film lubrication that has been termed "weeping lubrication," supplemented by "floating lubrication," though on occasions boundary conditions may prevail

Aims

The Mathys Affinis Short is the most frequently used stemless total shoulder prosthesis in the UK. The purpose of this prospective cohort study is to report the survivorship, clinical, and radiological outcomes of the first independent series of the Affinis Short prosthesis.

Our aim was to compare the outcome of arthroscopic release for frozen shoulder in patients with and without diabetes. We prospectively compared the outcome in 21 patients with and 21 patients without diabetes, two years post-operatively. The modified Constant score was used as the outcome measure. The mean age of the patients was 54.5 years (48 to 65; male:female ratio: 18:24), the mean pre-operative duration of symptoms was 8.3 months (6 to 13) and the mean pre-operative modified Constant scores were 36.6 (standard deviation (. sd. ) 4.6) and 38.4 (. sd. 5.7) in the diabetic and non-diabetic groups, respectively. The mean modified Constant scores at six weeks, six months and two years post-operatively in the diabetics were 55. 6 (. sd. 4.7), 67. 4 (. sd. 5.6) and 84. 4 (. sd. 6.8), respectively; and in the non-diabetics 66.8 (. sd. 4.5), 79.6 (. sd. 3.8) and 88.6 (. sd. 4.2), respectively. A total of 15 (71%) of diabetic patients recovered a full range of movement as opposed to 19 (90%) in the non-diabetics. There was significant improvement (p < 0.01) in the modified Constant scores following arthroscopic release for frozen shoulder in both groups. The results in diabetics were significantly worse than those in non-diabetics six months post-operatively (p < 0.01) with a tendency towards persistent limitation of movement two years after operation. These results may be used when counselling diabetic patients for the outcome after arthroscopic treatment of frozen shoulder. Cite this article: Bone Joint J 2014;96-B:1355–8
