Aims

The aim of this study was to investigate whether clinical and radiological outcomes after intramedullary nailing of displaced fractures of the fifth metacarpal neck using a single thick Kirschner wire (K-wire) are noninferior to those of technically more demanding fixation with two thinner dual wires.

We inserted an electrode up the femoral neck into the femoral head of ten patients undergoing a metal-on-metal hip resurfacing arthroplasty through a posterior surgical approach and measured the oxygen concentration during the operation. In every patient the blood flow was compromised during surgery, but the extent varied. In three patients, the oxygen concentration was zero at the end of the procedure. The surgical approach caused a mean 60% drop (p < 0.005) in oxygen concentration while component insertion led to a further 20% drop (p < 0.04). The oxygen concentration did not improve significantly on wound closure. This study demonstrates that during hip resurfacing arthroplasty, patients experience some compromise to their femoral head blood supply and some have complete disruption

A prospective study of 120 consecutive total hip replacements showed that deep suction drains produced maximal drainage volumes in the first 24 hours. Their continued presence resulted in minimal further drainage, did not reduce the likelihood of haematoma formation and led in some cases to the spread of skin organisms into the wound

Aims

The aim of this study was to utilize a national paediatric inpatient database to determine whether obesity influences the operative management and inpatient outcomes of paediatric limb fractures.

Traditional posterior approaches to the neck use a vertical craniocaudal incision which often leaves an unsightly scar. An incision along Langer's transverse lines of tension divides only the cross-fibres of the dermis and we have found the results of this approach encouraging: wound healing was uncomplicated and the cosmetic appearance excellent

Aims

The increasing infection burden after total hip arthroplasty (THA) has seen a rise in the use of two-stage exchange arthroplasty and the use of increasingly powerful antibiotics at the time of this procedure. As a result, there has been an increase in the number of failed two-stage revisions during the past decade. The aim of this study was to clarify the outcome of repeat two-stage revision THA following a failed two-stage exchange due to recurrent prosthetic joint infection (PJI).

Between December 2004 and June 2006, 136 patients (156 total hip replacements), were sent from the waiting list of the Cardiff Vale NHS Trust to the NHS Treatment Centre, Weston-super-Mare, in an attempt to reduce the waiting time for total hip replacement. Because of concerns about their outcome, each patient was contacted and invited to attend a review appointment with a consultant specialising in hip and revision hip replacement. A total of 98 patients (113 hips) were reviewed after a mean of 23 months (11 to 30). There were 104 cemented hips, seven hybrid and two cementless. An acetabular inclination of > 55° was seen in 18 (16%). Radiolucent lines around the acetabular component were seen in 76 (67%). The femoral component was in more than 4° of varus in 47 (42%). The medial floor had been breached in 13 (12%) and there was a leg-length discrepancy of more than 1 cm in ten (9%). There were three dislocations, one femoral fracture, one pulmonary embolus, one deep infection and two superficial wound infections. To date, 13% (15 hips) have been revised and a further 4% (five hips) await revision, mostly for a painful loose acetabular component. The revision rate far exceeds the 0.5% five-year failure rate reported in the Swedish Registry for the components used. This initiative and the consequent need for correction of the problems created, has significantly increased the workload of our unit

A method is described by which an artificial limb can be fitted as soon as an above-knee or below-knee amputation wound is healed, by using preformed sockets which enable the prosthetist to fit the limb within the hour. The method has been found safe, and better than other methods previously described to facilitate the early mobilisation and rehabilitation of the amputee

Aims

Antibiotic-loaded bone cements (ALBCs) may offer early protection against the formation of bacterial biofilm after joint arthroplasty. Use in hip arthroplasty is widely accepted, but there is a lack of evidence in total knee arthroplasty (TKA). The objective of this study was to evaluate the use of ALBC in a large population of TKA patients.

Aims

There is little literature about total knee arthroplasty (TKA) after distal femoral osteotomy (DFO). Consequently, the purpose of this study was to analyze the outcomes of TKA after DFO, with particular emphasis on: survivorship free from aseptic loosening, revision, or any re-operation; complications; radiological results; and clinical outcome.

Two cases of laterally open knee joints with surrounding skin defects are reported. The joints were closed by muscle flaps fashioned from the lateral belly of the gastrocnemius, which was detached distally and folded upwards and forwards to cover the defect. The transposed muscle and the remainder of the wound were covered by free skin grafts. Results were satisfactory

1. Six cases of infection of wounds with actinomyces are described alld tile cultural characteristics of tile organisms are discussed. 2. In three patients the infecting organism was an unusual aerobic form. 3. Possible sources of infection are considered. 4. The chronicity of the condition and the difficulty in treatment are stressed. 5. Penicillin and X-radiation hold out most hope of cure

A 16-year-old boy was involved in an agricultural accident in which he sustained a large wound to the right arm and forearm. Radiological examination showed loss of the distal half of the humerus. A posterior splint was applied and after two months there was regeneration of the distal humerus including the articular portion. He was able to use his arm at five months. Twenty years later, he had a painless elbow and a 70° range of movement

Exposure of the prosthesis is one of the problems encountered after arthroplasty of the knee. Eight patients with nine exposed prostheses have been treated by using a gastrocnemius myocutaneous flap to provide cover. This preserved the prosthesis and closed the joint in six of the eight patients.l The factors leading to breakdown of the wound are discussed and the anatomy of the gastrocnemius myocutaneous flap and the operative procedure are described

1. The behaviour of penicillin injected locally into knee joints is investigated and found to be the only satisfactory way of using the drug in joint wounds and infections. 2. Penicillin persists within the joint for forty-eight hours after injection unless the effusion is being actively absorbed. 3. The additional administration of penicillin by intramuscular injection is recommended when other considerations demand it

Traumatic hemipelvectomy is rare, and is usually accompanied by injury to the genito-urinary tract and bowel. Recently, there have been an increasing number of reports of patients who have survived this injury, probably as a result of improved early care. We report three such cases and review the literature. The amputation wound should not be closed initially; early re-exploration to remove any dead tissue is indicated, and this should be repeated as necessary

Objectives

The long head of the biceps (LHB) is often resected in shoulder surgery and could therefore serve as a cell source for tissue engineering approaches in the shoulder. However, whether it represents a suitable cell source for regenerative approaches, both in the inflamed and non-inflamed states, remains unclear. In the present study, inflamed and native human LHBs were comparatively characterized for features of regeneration.

The scalpel blades used during 187 operations were cultured. At each procedure the knife used to incise the skin was discarded immediately and a fresh knife was used to complete the operation. The results showed that there was no difference in the bacterial growth between the two knives. From these results it would appear that the practice of changing blades after incising the skin is an unnecessary precaution in the prevention of bacterial contamination of clean wounds
