We explored the trends over time and the geographical variation in the use of subacromial decompression and rotator cuff repair in 152 local health areas (Primary Care Trusts) across England. The diagnostic and procedure codes of patients undergoing certain elective shoulder operations between 2000/2001 and 2009/2010 were extracted from the Hospital Episode Statistics database. They were grouped as 1) subacromial decompression only, 2) subacromial decompression with rotator cuff repair, and 3) rotator cuff repair only. The number of patients undergoing subacromial decompression alone rose by 746.4% from 2523 in 2000/2001 (5.2/100 000 (95% confidence interval (CI) 5.0 to 5.4) to 21 355 in 2009/2010 (40.2/100 000 (95% CI 39.7 to 40.8)). Operations for rotator cuff repair alone peaked in 2008/2009 (4.7/100 000 (95% CI 4.5 to 4.8)) and declined considerably in 2009/2010 (2.6/100 000 (95% CI 2.5 to 2.7)). Given the lack of evidence for the effectiveness of these operations and the significant increase in the number of procedures being performed in England and elsewhere, there is an urgent need for well-designed clinical trials to determine evidence of clinical effectiveness.

We treated post-traumatic contracture of the elbow in 13 consecutive patients (14 elbows) by operative release. Through a single medial approach, the posterior oblique bundle of the medial collateral ligament was resected, followed by posterior and anterior capsulectomies. An additional lateral release through a separate incision was required in only four elbows. The results were assessed at a mean interval of 57 months after operation. Before surgery active extension lacked 43° which improved to 17° after operation. Active flexion before operation was 89°, which improved to 127°. The mean arc of movement increased from 46° to 110°. All 14 elbows showed scarring of the posterior oblique bundle of the medial collateral ligament. Neither the interval from injury to operative release nor the age of the patient affected the results. A medial approach is useful to reveal and excise the pathological changes in the medial collateral ligament. It is a safe and effective route through which to correct post-traumatic contracture of the elbow

Narrowing of the femoral neck after resurfacing arthroplasty of the hip has been described previously in both cemented and uncemented hip resurfacing. The natural history of narrowing of the femoral neck is unknown. We retrospectively measured the diameter of the femoral neck in a series of 163 Birmingham hip resurfacings in 163 patients up to a maximum of six years after operation to determine the extent and progression of narrowing. There were 105 men and 58 women with a mean age of 52 years (18 to 82). At a mean follow-up of five years, the mean Harris hip score was 94.8 (47 to 100) and the mean flexion of the hip 112.5° (80° to 160°). There was some narrowing of the femoral neck in 77% (125) of the patients reviewed, and in 27.6% (45) the narrowing exceeded 10% of the diameter of the neck. A multiple logistic regression analysis showed a significant association (chi-squared test (derived from logistic regression) p = 0.01) of narrowing with female gender and a valgus femoral neck/shaft angle. There was no significant association between the range of movement, position or size of the component or radiological lucent lines and narrowing of the neck (chi-squared test; p = 0.10 (flexion), p = 0.08 (size of femoral component), p = 0.09 (size of acetabular component), p = 0.71 (femoral component angulation), p = 0.99 (lucent lines)). There was no significant difference between the diameter of the neck at a mean of three years (2.5 to 3.5) and that at five years (4.5 to 5.5), indicating that any change in the diameter of the neck had stabilised by three years (sign rank test, p = 0.60). We conclude that narrowing of the femoral neck which is found with the Birmingham hip resurfacing arthroplasty is in most cases associated with no adverse clinical or radiological outcome up to a maximum of six years after the initial operation

We present the results of 525 primary Souter elbow arthroplasties undertaken in 406 patients between 1982 and 1997. There were 372 women and 34 men with a mean age of 57 years; 119 patients had a bilateral procedure. The elbows were affected by chronic inflammatory disease, usually rheumatoid arthritis, which had been present for a mean of 24.7 years (2 to 70). In about 30% the joints were grossly destroyed with significant loss of bone. In 179 elbows the ulnar components were metal-backed and retentive; in the remaining 346, with better bone stock, non-retentive, all-polyethylene prostheses were used. Because of complications, 108 further operations were required in 82 patients. During the early years the incidence of complications was higher. Dislocation was the indication for 30 further procedures in 26 patients. Thirty patients underwent 33 revision procedures for aseptic loosening, 12 had 29 operations because of deep infection, two for superficial infection, and 14 further operations were done for other reasons. The cumulative rate of success, without aseptic loosening, five and ten years after surgery, was 96% and 85%, respectively

We analysed the long-term results of arthrodesis of the shoulder after infection in 15 patients. At the time of operation, 14 cultures were positive for Staphylococcus aureus. The mean follow-up was 8.3 years (3 to 14) and 90% of the patients were satisfied with the outcome. There were complications in five patients (33%); in three there was nonunion with loosening of the implant. One patient had a sound bony union but with a persistent sinus six years after arthrodesis and another had a sinus which healed after the metal was removed. Four of these five patients (80%) were heavy smokers (> 20 cigarettes/day). Cancellous bone grafting did not affect the incidence of complications. The mean age of the patients with complications was 58.6 v 48.6 years for those without (p = 0.2808 ; not significant). Those with complications had had more previous operations (6.4 v 2.5, p < 0.05). Antibiotics, as determined by the bacteriological cultures, were administered for six weeks. The complication rate was higher in patients with active sepsis but the younger the patient and the fewer number of previous operations (< 50 years, < four previous operations), the better was the outcome. Considering the rate of complications, we recommend early surgery in these patients

We report the results of a prospective study of 23 patients in which interstitial laser photocoagulation (ILP) was used to treat an osteoid osteoma. ILP is a technique in which tumour tissue is destroyed by direct heating using low-power laser light energy delivered by thin (400 μm) optical fibres which are introduced percutaneously into the tumour under image guidance. Pain was evaluated before operation and at the latest follow-up using a visual analogue scale with 0 denoting no pain and 10 the worst pain imaginable. The mean follow-up was for 15 months. The results showed that the mean pain score decreased from 7.5 before operation to 0.95 at the latest follow-up. Fourteen patients had no pain and eight had minor discomfort, not requiring analgesia. One patient required a second procedure because placement of the fibre had not been accurate enough and one developed recurrent symptoms eight months after treatment. All patients were satisfied with the operation because of the rapid resolution of pain, the minimally invasive nature of the procedure, and the fact that there was no postoperative restriction of activity

Aims

Plate and screw fixation has been the standard treatment for painful conditions of the wrist in non-rheumatoid patients in recent decades. We investigated the complications, re-operations, and final outcome in a consecutive series of patients who underwent wrist arthrodesis for non-inflammatory arthritis.

We studied perioperative pain and postoperative neurological changes after surgery for hallux valgus in 50 patients operated on under local ankle block. Patients were randomised to have the pneumatic tourniquet either at calf level or just above the ankle. The cuffs were inflated to 100 mmHg above systolic blood pressure. One patient was withdrawn from the study after randomisation. Areas of pain, paraesthesia and numbness were marked by patients on a diagram of the foot before operation and at six and ten weeks after operation. Both positions of the tourniquet gave an excellent bloodless field. The proximal tourniquet gave significantly greater discomfort (p < 0.01) during the operation, after 10, 20 and 30 minutes. Application of the cuff at the ankle gave no relative increase in areas of numbness and paraesthesia at six and ten weeks. An ankle tourniquet gives less discomfort with no increase in the incidence of nerve injury

To determine the effect of cordotomy on the function of the bladder during surgical correction of congenital kyphosis in myelomeningocele, we reviewed 13 patients who had this procedure between 1981 and 1996. The mean age of the patients at operation was 8.9 years (3.7 to 16) and the mean follow-up was 4.8 years (1.3 to 10.8). Bladder function before and after operation was assessed clinically and quantitatively by urodynamics. The mean preoperative kyphosis was 117° (52 to 175) and decreased to 49° (1 to 89) immediately after surgery. At the latest follow-up, a mean correction of 52% had been achieved. Only one patient showed deterioration in bladder function after operation. Eight out of the nine patients who had urodynamic assessment had improvement in bladder capacity and compliance, and five showed an increase in urethral pressure. One patient developed a spastic bladder and required subsequent surgical intervention. Cordotomy, at or below the level of the kyphosis, allows excellent correction of the structural deformity

The relationship between post-operative bone density and subsequent failure of total knee replacement (TKR) is not known. This retrospective study aimed to determine the relationship between bone density and failure, both overall and according to failure mechanism. All 54 aseptic failures occurring in 50 patients from 7760 consecutive primary cemented TKRs between 1983 and 2004 were matched with non-failing TKRs, and 47 failures in 44 patients involved tibial failures with the matching characteristics of age (65.1 for failed and 69.8 for non-failed), gender (70.2% female), diagnosis (93.6% OA), date of operation, bilaterality, pre-operative alignment (0.4 and 0.3 respectively), and body mass index (30.2 and 30.0 respectively). In each case, the density of bone beneath the tibial component was assessed at each follow-up interval using standardised, calibrated radiographs. Failing knees were compared with controls both overall and, as a subgroup analysis, by failure mechanism. Knees were compared with controls using univariable linear regression. Significant and continuous elevation in tibial density was found in knees that eventually failed by medial collapse (p < 0.001) and progressive radiolucency (p < 0.001) compared with controls, particularly in the medial region of the tibia. Knees failing due to ligamentous instability demonstrated an initial decline in density (p = 0.0152) followed by a non-decreasing density over time (p = 0.034 for equivalence). Non-failing knees reported a decline in density similar to that reported previously using dual-energy x-ray absorptiometry (DEXA). Differences between failing and non-failing knees were observable as early as two months following surgery. This tool may be used to identify patients at risk of failure following TKR, but more validation work is needed. Cite this article: Bone Joint J 2014;96-B:1503–9

The lateral substitution reconstruction operation described by MacIntosh has been evaluated in 27 patients with chronic anterior cruciate ligament deficiency of the knee. The results, at an average of 11.3 years after operation, have been assessed by a scoring system which allocates a maximum of 25 points each for function and for clinical evaluation. Emphasis was placed on subjective giving way and objective evidence of a positive anterior drawer sign and a positive lateral pivot shift test. A score of 46 to 50 was classified as excellent, 41 to 46 as fair, and less than 41 was a poor result: 52% scored excellent, 26% fair and 22% were poor. Most of those with poor results had had evidence of osteoarthritis at the time of operation. Despite the recorded scores, no less than 75% of the patients at long-term follow-up were subjectively improved, and able to maintain an active life style

A new and simple operative technique has been developed to provide rigid internal fixation for all types of fractures of the scaphoid. This involves the use of a double-threaded bone screw which provides such good fixation that, after operation, a plaster cast is rarely required and most patients are able to return to work within a few weeks. A classification of scaphoid fractures is proposed. The indications for operation included not only acute unstable fractures, but also fractures with delayed healing and those with established non-union; screw fixation was combined with bone grafting to treat non-union. In a prospective trial, 158 operations using this technique were carried out between 1977 and 1981. The rate of union was 100 per cent for acute fractures and 83 per cent overall. This method of treatment appears to offer significant advantages over conventional techniques in the management of the fractured scaphoid

This paper describes the relationship between post-myelographic symptoms and the timing of a subsequent spinal operation. A prospective study was performed comparing the post-operative symptoms of patients who underwent discectomy within 48 hours of myelography (Group 1) with those of patients who underwent discectomy at least seven days after myelography (Group 2). After myelography there was no statistical difference in the incidence of nausea and headache in the two groups. However, after operation the incidence of headache and nausea was significantly greater in patients who underwent early discectomy. The incidence of urinary retention was significantly greater in Group 1 at 24 hours after operation but not at 48 and 72 hours. We conclude that the temptation to perform discectomy shortly after myelography should be resisted until at least one week has elapsed between the two procedures, except in emergency situations

Aims. The aim of this study was to determine whether chilled irrigation saline decreases the incidence of clinical upper limb palsy (ULP; a reduction of one grade or more on manual muscle testing; MMT), based on the idea that ULP results from thermal damage to the nerve roots by heat generated by friction during bone drilling. Methods. Irrigation saline for drilling was used at room temperature (RT, 25.6°C) in open-door laminoplasty in 400 patients (RT group) and chilled to a mean temperature of 12.1°C during operations for 400 patients (low-temperature (LT) group). We assessed deltoid, biceps, and triceps brachii muscle strength by MMT. ULP occurring within two days post-operatively was categorised as early-onset palsy. Results. The incidence of ULP (4.0% vs 9.5%, p = 0.003), especially early-onset palsy (1.0% vs 5.5%, p < 0.001), was significantly lower for the LT group than for the RT group. Multivariate analysis indicated that RT irrigation saline use, concomitant foraminotomy, and opened side were significant predictors for ULP. Discussion. Using chilled irrigation saline during bone drilling significantly decreased the ULP incidence, particularly the early-onset type, and shortened the recovery period for ULP. Chilled irrigation saline can thus be recommended as a simple method for preventing ULP. Take home message: Chilled irrigation during laminoplasty reduces C5 palsy.

Thirty-three patients who had undergone anterior cervical fusion for degenerative disc disease were reviewed to determine the efficacy of the procedure. Only patients who were available for examination and who had undergone operation at least one year previously were included in the review. Nearly all had had arm pain and three-quarters neck pain. Diminished neck movement and neurological abnormalities in the arms had been frequent findings. Diagnosis from the clinical features and plain radiographs is described. Myelography was not used routinely and discography was not used at all. Indications for operation and surgical technique are described. Results show that pain in the neck and arm was relieved in a high proportion of cases and that the neurological abnormalities often recovered. It is concluded that this operation is safe and has a definite place in the relief of pain from cervical disc degeneration resistant to conservative treatment

1. One hundred and twenty-three patients with rheumatoid arthritis who had synovectomy and excision of the head of the radius performed on 154 elbows have been reviewed one to six years after operation. 2. The severity of the disease process at the time of operation was graded radiologically and an attempt made to relate this to the results. 3. Overall, the clinical results were most satisfactory; more than 70 per cent of the patients were pleased with the outcome. When radiographic deterioration of the joint was taken into account, however, only 54 per cent achieved a "satisfactory" result. 4. Clearance of the synovium through combined medial and lateral incisions gave better results than a lateral approach alone. 5. When the disease was far advanced by the time of operation any good results were likely to be short-lived. 6. The indications for synovectomy of the rheumatoid elbow are discussed in the light of these findings

1. Two hundred and seventeen low-friction arthroplasties performed between November 1962 and April 1969 in 203 patients with failed previous operations have been analysed. 2. The technical details of operation in relation to these conversion problems have been outlined. 3. The quality of the results in relation to pain, mobility and ability to walk has been assessed before operation and one year afterwards, with small numbers at three and five years. 4. Pain was completely relieved or was minimal in 96·3 per cent of the patients, and in no case was the pain worse. 5. The total range of movement was 100 degrees or more in 98·5 per cent. No hip lost movement after conversion. 6. The failures were principally due to infection and to technical difficulties. There were no mechanical failures without a technical or radiological explanation. 7. Low-friction arthroplasty is an excellent salvage procedure, especially for failed cup arthroplasty

1. Two cases of recurrent post-traumatic dislocation of the hip are reported. 2. The literature is reviewed and the rarity of the condition is emphasised. Only twenty-two cases have been previously reported, eleven in adults and eleven in children. 3. The sequence of events leading to recurrent dislocation is not understood but the following important facts emerge. The initial incident could not be distinguished from that causing uncomplicated dislocations. There was a significant delay in reduction in a number of cases. Subsequent dislocations followed minor injury. A large defect in the posterior capsule with a large synovial-lined pouch or false joint was found at operation in both our cases. The ligamentum teres was not seen at operation. The surgeon was unable to redislocate the hips during the operation. 4. In both cases reported here treatment was by excision of the posterior pouch and repair of the capsular defect. 5. Based on the above facts some tentative deductions are made

1. Stainless steel mould arthroplasty of the knee is described and a ten-year follow-up study of sixty-two operations is reported. Fifty-four were for rheumatoid arthritis and eight for osteoarthritis. 2. Forty-nine of the sixty-two joints retained mobility, six had become ankylosed and five were later arthrodesed ; two limbs were amputated. The forty-nine mobile knees included twenty-seven which were painless at all times, and fourteen in which only an occasional twinge was felt. 3. The range of movement was increased in twenty-two joints as compared with the state before operation, diminished in twelve and unaltered in five. In ten knees measurements before operation were not available. 4. Flexion deformity, swelling, stability and function were improved in a significant number of joints. 5. Patients suffering from active rheumatoid arthritis often found that the joint operated upon no longer took part in generalised flares of the disease
