The commonest site of osseous tuberculosis is the spine. Most vertebral lesions are contiguous. Current research indicates the incidence of multiple level noncontiguous vertebral tuberculosis is 1.1% to 16%. The aim of this study was to identify the incidence of multiple level noncontiguous vertebral tuberculosis using whole spine magnetic resonance imaging (MRI). A retrospective review was undertaken of case notes and whole spine MRI studies of all acute spinal infection cases that presented to a regional Spinal Unit over 3 years. Patients were included if spinal infection was identified by whole spine MRI and confirmed as tuberculosis by a combination of histology and microbiology. The incidence of multiple level noncontiguous vertebral tuberculosis was 71.4%. This is higher than previously quoted when MRI is not undertaken. Tuberculosis may affect the spine at multiple noncontiguous sites more frequently than thought previously. A large proportion of the affected noncontiguous sites may also be asymptomatic. We currently perform whole spine MRI on all patients with suspected spinal infection to aid detection of multiple level noncontiguous tuberculosis.

Primary giant cell tumours involving digital bones of the hand are rare lesions which are generally diagnosed at an advanced stage. Accurate diagnosis requires clinical evaluation, imaging studies and histopathological assessment. Conservative treatment by digit-sparing surgery is associated with high recurrence rates. In a ten year retrospective review, this study identified only four cases. Three cases involved a phalanx and were treated by distal amputation of the involved digit. None recurred. One involved the metacarpal and recurred twice following repeated curettage and bone grafting. No further recurrence has been detected after resection and replacement with a non-vascularised fibular graft and Silastic implant replacement of the metacarpophalangeal joint. Our small series of cases supports a policy of aggressive primary surgery, including amputation or en bloc resection and reconstruction.

Sidestep cutting, irrespective of the modern soccer boot type worn, may be implicated in the high incidence of noncontact soccer anterior cruciate ligament injuries by significantly altering knee loading.

Abductor tendon lesions and insertional tendinopathy are the most common causes of lateral thigh pain. Gluteal tendon pathology is more prevalent in women and frequency increases with age. Chronic atraumatic tears result in altered lower limb biomechanics. The chief complaint is lateral thigh pain. Clinical examination should include evaluation of muscle strength, lumbar spine, hip and fascia lata pathology. The hip lag sign and 30-second single leg stance tests are useful in diagnosing abductor insufficiency. Magnetic resonance imaging (MRI) is the gold-standard investigation to identify abductor tendon tears and evaluate the extent of muscle fatty infiltration that has predictive value on the outcome of abductor repair. Abductor tendinosis treatment is mainly conservative, including non-steroidal anti-inflammatory medications, activity modification, local corticosteroid injections, plasma-rich protein, physical and radial shockwave therapy. The limited number of available high-quality studies on treatment outcomes and limited evidence between tendinosis and partial ruptures make it difficult to provide definite conclusions regarding the best management of gluteal tendinopathy. Surgical management is indicated in complete and partial gluteal tendon tears that are unresponsive to conservative treatment. There are various open and arthroscopic surgical procedures for direct repair of abductor tendon tears. There is limited evidence concerning surgical management outcomes. Prerequisites for effective tendon suturing are neurologic integrity and limited muscle fatty infiltration. Chronic irreparable tears with limited muscle atrophy and limited fatty infiltration can be augmented with grafts. Gluteus maximus or/vastus lateralis muscle transfers are salvage reconstruction procedures for the management of chronic end-stage abductor tears with significant tendon insufficiency or gluteal atrophy.

Aims Despite the increase in the surgical repair of proximal hamstring tears, there exists a lack of consensus in the optimal timing for surgery. There is also disagreement on how partial tears managed surgically compare with complete tears repaired surgically. This study aims to compare the mid-term functional outcomes in, and operating time required for, complete and partial proximal hamstring avulsions, that are repaired both acutely and chronically. Methods This is a prospective series of 156 proximal hamstring surgical repairs, with a mean age of 48.9 years (21.5 to 78). Functional outcomes were assessed preinjury, preoperatively, and postoperatively (six months and minimum three years) using the Sydney Hamstring Origin Rupture Evaluation (SHORE) score. Operating time was recorded for every patient. Results Overall, significant improvements in SHORE scores were seen at both six months and mid-term follow-up. Preoperatively, acute patients (median score 27.1 (interquartile range (IQR) 22.9)) reported significantly poorer SHORE scores than chronic patients (median score 42.9 (IQR 22.1); p < 0.001). However, this difference was not maintained postoperatively. For partial tears, acutely repaired patients reported significantly lower preoperative SHORE scores compared to chronically reapired partial tears (median score 24.3 (IQR 15.7) vs median score 40.0 (IQR 25.0); p < 0.001) but also significantly higher SHORE scores at six-month follow-up compared to chronically repaired partial tears (median score 92.9 (IQR 10.7) vs. median score 82.9 (IQR 14.3); p < 0.001). For complete tears, there was only a difference in preoperative SHORE scores between acute and chronic groups. Overall, acute repairs had a significantly shorter operating time (mean 64.67 minutes (standard deviation (SD) 12.99)) compared to chronic repairs (mean 74.71 minutes (SD = 12.0); t = 5.12, p < 0.001). Conclusion Surgical repair of proximal hamstring avulsions successfully improves patient reported functional outcomes in the majority of patients, irrespective of the timing of their surgery or injury classification. However, reducing the time from injury to surgery is associated with greater improvement in patient outcomes and an increased likelihood of returning to preinjury functional status. Acute repair appears to be a technically less complex procedure, as indicated by reduced operating times, postoperative neurological symptoms and number of patients requiring bracing. Acute repair is therefore a preference among many surgeons. Cite this article: Bone Joint J 2020;102-B(10):1419–1427.

ObjectivesWe performed a systematic review of the literature to determine the safety and efficacy of bone morphogenetic protein (BMP) compared with bone graft when used specifically for revision spinal fusion surgery secondary to pseudarthrosis.MethodsThe MEDLINE, EMBASE and Cochrane Library databases were searched using defined search terms. The primary outcome measure was spinal fusion, assessed as success or failure in accordance with radiograph, MRI or CT scan review at 24-month follow-up. The secondary outcome measure was time to fusion.ResultsA total of six studies (three prospective and three retrospective) reporting on the use of BMP2 met the inclusion criteria (203 patients). Of these, four provided a comparison of BMP2 and bone graft whereas the other two solely investigated the use of BMP2. The primary outcome was seen in 92.3% (108/117) of patients following surgery with BMP2. Although none of the studies showed superiority of BMP2 to bone graft for fusion, its use was associated with a statistically quicker time to achieving fusion. BMP2 did not appear to increase the risk of complication.ConclusionThe use of BMP2 is both safe and effective within the revision setting, ideally in cases where bone graft is unavailable or undesirable. Further research is required to define its optimum role.Cite this article: Mr P. Bodalia.

Aims To validate the Sydney Hamstring Origin Rupture Evaluation (SHORE), a hamstring-specific clinical assessment tool to evaluate patient outcomes following surgical treatment. Methods A prospective study of 70 unilateral hamstring surgical repairs, with a mean age of 47.3 years (15 to 73). Patients completed the SHORE preoperatively and at six months post-surgery, and then completed both the SHORE and Perth Hamstring Assessment Tool (PHAT) at three years post-surgery. The SHORE questionnaire was validated through the evaluation of its psychometric properties, including; internal consistency, reproducibility, reliability, sensitivity to change, and ceiling effect. Construct validity was assessed using Pearson’s correlation analysis to examine the strength of association between the SHORE and the PHAT. Results The SHORE demonstrated an excellent completion rate (100%), high internal consistency (Cronbach’s alpha 0.78), and good reproducibility (intraclass correlation coefficient (ICC) 0.82). The SHORE had a high correlation with the validated PHAT score. It was more sensitive in detecting clinical change compared to the PHAT. A ceiling effect was not present in the SHORE at six months; however, a ceiling effect was identified in both scores at three years post-surgery. Conclusion This study has validated the SHORE patient reported outcome measure (PROM) as a short, practical, reliable, valid, and responsive tool that can be used to assess symptom and function following hamstring injury and surgical repair.

International audienceThe superficial branch of the radial nerve (SBRN) is potentially at risk during thumb carpometacarpal (TCM) or thumb metacarpophalangeal (TMP) joint arthroscopy. The aim of this anatomical study was to describe the different branching patterns of the SBRN and to optimize positioning of portals during TCM and TMP arthroscopy. The SBRN was dissected in 30 forearms. Three branches of the nerve (SR1, SR2, and SR3) were recorded and distances between SBRN branches and portals used for carpometacarpal (TCM) and metacarpophalangeal (TMP) joints of the thumb arthroscopy were measured. Three main portals were used for TCM joint arthroscopy. These portals were an ulnar portal (1-U), a radial portal (1-R), and an accessory portal (D-2). A radial metacarpophalangeal (MCP-rad) and an ulnar metacarpophalangeal (MCP-uln) portal were used for TMP joint arthroscopy. In 24 cases (80%), the 1-R portal was inserted radially (volar) to SR3 at a mean distance of 4.8 mm (0-8). In the remaining six cases (20%) when 1-R portal was inserted ulnar (dorsal) to SR3, the distance was less than 2 mm in all cases. SR3 was always far from the 1-U portal at a mean 13 mm (7-22). The D-2 portal was always close to SR2-D1 at a mean distance of 1.7 mm (0-6). The distance from SR2-D2 and D-2 portal was also inferior by 5 mm. At the level of the metacarphalangeal joint of the thumb, the MCP-rad portal was always situated dorsally and very close to SR3, at a mean distance of 1 mm (0-5). The MCP-uln portal was also situated dorsal to SR2-D1 at a mean distance of 3.7 mm (1.5-6.5). The results of this anatomical study confirm actual reported findings about the SR2 and SR3 branches. These two branches of the SBRN are the most at risk of injury during TCM and TMP joint arthroscopy. According to our measurements, the 1-U portal is a safer portal than 1-R and D-2 portal for TCM arthroscopy and should be preferred for surgery necessitating only one portal. Concerning TMP arthroscopy, the SBRN appears less at risk of injury when using a MCP-uln portal and safer than MCP-rad which is at risk at less than 5 mm from the extensor pollicis longus tendon
