Aims

Biofilm infections are among the most challenging complications in orthopaedics, as bacteria within the biofilms are protected from the host immune system and many antibiotics. Halicin exhibits broad-spectrum activity against many planktonic bacteria, and previous studies have demonstrated that halicin is also effective against Staphylococcus aureus biofilms grown on polystyrene or polypropylene substrates. However, the effectiveness of many antibiotics can be substantially altered depending on which orthopaedically relevant substrates the biofilms grow. This study, therefore, evaluated the activity of halicin against less mature and more mature S. aureus biofilms grown on titanium alloy, cobalt-chrome, ultra-high molecular weight polyethylene (UHMWPE), devitalized muscle, or devitalized bone.

Rotator cuff pathology is the main cause of shoulder pain and dysfunction in older adults. When a rotator cuff tear involves the subscapularis tendon, the symptoms are usually more severe and the prognosis after surgery must be guarded. Isolated subscapularis tears represent 18% of all rotator cuff tears and arthroscopic repair is a good alternative primary treatment. However, when the tendon is deemed irreparable, tendon transfers are the only option for younger or high-functioning patients. The aim of this review is to describe the indications, biomechanical principles, and outcomes which have been reported for tendon transfers, which are available for the treatment of irreparable subscapularis tears.

The best tendon to be transferred remains controversial. Pectoralis major transfer was described more than 30 years ago to treat patients with failed surgery for instability of the shoulder. It has subsequently been used extensively to manage irreparable subscapularis tendon tears in many clinical settings. Although pectoralis major reproduces the position and orientation of the subscapularis in the coronal plane, its position in the axial plane – anterior to the rib cage – is clearly different and does not allow it to function as an ideal transfer. Consistent relief of pain and moderate recovery of strength and function have been reported following the use of this transfer. In an attempt to improve on these results, latissimus dorsi tendon transfer was proposed as an alternative and the technique has evolved from an open to an arthroscopic procedure. Satisfactory relief of pain and improvements in functional shoulder scores have recently been reported following its use. Both pectoralis minor and upper trapezius transfers have also been used in these patients, but the outcomes that have been reported do not support their widespread use.

Aims

There are concerns regarding complications and longevity of total elbow arthroplasty (TEA) in young patients, and the few previous publications are mainly limited to reports on linked elbow devices. We investigated the clinical outcome of unlinked TEA for patients aged less than 50 years with rheumatoid arthritis (RA).

Aims

To investigate the risk factors for unsuccessful radial head reduction (RHR) in children with chronic Monteggia fractures (CMFs) treated surgically.

Aims

The aim of this study was to investigate the outcome of periprosthetic fractures of the humerus and to assess the uniformity of the classifications used for these fractures (including those around elbow and/or shoulder arthroplasties) by performing a systematic review of the literature.

Upper limb amputations, ranging from transhumeral to partial hand, can be devastating for patients, their families, and society. Modern paradigm shifts have focused on reconstructive options after upper extremity limb loss, rather than considering the amputation an ablative procedure. Surgical advancements such as targeted muscle reinnervation and regenerative peripheral nerve interface, in combination with technological development of modern prosthetics, have expanded options for patients after amputation. In the near future, advances such as osseointegration, implantable myoelectric sensors, and implantable nerve cuffs may become more widely used and may expand the options for prosthetic integration, myoelectric signal detection, and restoration of sensation. This review summarizes the current advancements in surgical techniques and prosthetics for upper limb amputees.

Aims

This study reports updates the previously published two-year clinical, functional, and radiological results of a group of patients who underwent transfibular total ankle arthroplasty (TAA), with follow-up extended to a minimum of five years.

1. The possibilities in the treatment of the elbow in arthrogryposis are discussed. 2. The role of tricepsplasty to gain movement, and of triceps transfer to obtain power are outlined and the results obtained in the surgical treatment of twenty-three elbows are analysed

Aims

The decrease in the number of satellite cells (SCs), contributing to myofibre formation and reconstitution, and their proliferative capacity, leads to muscle loss, a condition known as sarcopenia. Resistance training can prevent muscle loss; however, the underlying mechanisms of resistance training effects on SCs are not well understood. We therefore conducted a comprehensive transcriptome analysis of SCs in a mouse model.

Aims

Sarcopenia is characterized by a generalized progressive loss of skeletal muscle mass, strength, and physical performance. This systematic review primarily evaluated the effects of sarcopenia on postoperative functional recovery and mortality in patients undergoing orthopaedic surgery, and secondarily assessed the methods used to diagnose and define sarcopenia in the orthopaedic literature.

We reviewed 26 patients who had had internal fixation of an open intra-articular supracondylar fracture of the humerus. All operations were performed using a posterior approach, 13 with a triceps split and 13 with an olecranon osteotomy. The outcome was assessed by means of the Mayo Elbow score, the Disability of the Arm, Shoulder and Hand (DASH) score and the SF-36 Physical Function score. Patients with an olecranon osteotomy had less good results

Seven children with chronic post-traumatic dislocation of the radial head were treated by open reduction and ligament reconstruction by a triceps tendon slip. In the four patients with anterior dislocation, good results were achieved; in the two with anterolateral dislocations bowing of the ulna persisted and subluxation recurred. One patient with an anterior dislocation developed a radio-ulnar synostosis. For anterolateral dislocations, we advise the combining of open reduction and ligament reconstruction with osteotomy of the ulna

We report the use of a new approach for elbow arthroplasty in 58 cases over a 20-year period. A wide exposure, obtained by elevating the triceps attachment and dividing the radial collateral ligament, allows the excision of diseased tissue, articular irregularities and osteophytes. Normal anatomy is restored and active mobilisation can be started 10 days after operation. Good or fair results, with over 70 degrees of joint movement, were achieved in 88% of cases

This study describes the surgical technique used for reconstruction and reinforcement of the lateral collateral ligament complex in patients with posterolateral instability of the elbow and the results. A triceps tendon graft from the ipsilateral elbow which was inserted through bone tunnels and fixed with bone anchors augmented the reconstruction. The operation was performed on 18 consecutive patients with instability after an acute traumatic dislocation. The mean follow-up was 44 months (14 to 88). There were no recurrent dislocations. The elbow was stable in 14 patients; three had some minor limitation of movement. Thirteen had no or only occasional slight pain, 15 returned to their normal level of activity and 17 were satisfied with the outcome. There was only one failure

In paralytic lesions in which the triceps surae is the only active muscle in the leg, elongation or division of the tendo calcaneus alone may not be enough to prevent recurrence of equinus deformity. In 10 patients (13 limbs) with this pattern of muscle activity, equinus deformity was treated by hemitransplantation of the tendo calcaneus. At follow-up, which was beyond the end of growth in seven limbs, there was no recurrence of deformity in nine. In three of the four failures, a technical fault may have caused loss of activity in the transplanted part of the tendon. The two-stage operation described is recommended in the management of this pattern of paralytic deformity

Thirteen patients with ruptures of the calcaneal tendon diagnosed more than four weeks after injury were reviewed. Eleven patients had operative reconstruction with tendon shortening and the postoperative follow-up ranged from one to seven years. Isometric and isokinetic measurements, as well as the strength of the triceps surae, all compared favourably with the normal contralateral leg. Only one tendon re-ruptured. Eight of the eleven patients were satisfied with the results and the two patients who had refused reconstruction had worse functional results. Late reconstruction of a ruptured calcaneal tendon is thus a worthwhile procedure

We have reviewed 50 patients at a mean period of 2.7 years after operations to restore elbow flexion lost as a result of traction injuries of the brachial plexus. A variety of operations were used and, in general, patient satisfaction was high. Objectively, however, the power in the transferred muscles was poor; less than half of the patients had a significant improvement in function. Poor control of the shoulder often compromised the result. Latissimus dorsi and triceps transfers proved most reliable, and some Steindler flexorplasties also gave satisfactory results. Pectoralis major transfers were disappointing and we do not recommend their use in women

1. Correction of equinus deformity in cerebral palsy either by elongation of the tendo calcaneus or by gastrocnemius recession gives satisfactory results without splintage or bracing after operation. 2. Gastrocnemius recession is the operation of choice in paraplegic spastic cerebral palsy, and wherever possible in tetraplegic cerebral palsy. In hemiplegia the whole of the triceps surae is usually involved, and elongation of the tendo calcaneus is almost always needed. 3. Correction at operation should aim to result in a mild degree of equinus deformity at the end of the growth period in hemiplegic spastic cerebral palsy. Over-enthusiastic gastrocnemius recession can lead to excessive weakness of the calf in some patients

We report the technique and results of a new method of debridement arthroplasty for advanced primary osteoarthritis of the elbow. Triceps and the periosteum of the olecranon are reflected towards the ulnar side and the joint is opened by dividing the radial collateral ligament. Osteophytes are removed, the olecranon and coronoid fossae are deepened and the fibrosed anterior joint capsule is excised. The degenerative changes are always more advanced on the radial side, with erosion of the capitellum, and it is usually necessary to remodel the head of the radius. In 29 elbows reviewed at a mean of 64 months, the average gain of range of motion was 34 degrees, with good pain relief and improved grip in most patients. Two elbows required reoperation but there were no other serious complications
