Aims

Total hip arthroplasty (THA) in patients with post-polio residual paralysis (PPRP) is challenging. Despite relief in pain after THA, pre-existing muscle imbalance and altered gait may cause persistence of difficulty in walking. The associated soft tissue contractures not only imbalances the pelvis, but also poses the risk of dislocation, accelerated polyethylene liner wear, and early loosening.

The results of surgical treatment of post-traumatic elbow contractures in adolescence have been conflicting in the literature. Some authors suggest that contracture release in this age group is less predictable and results less favorable than in adults. A retrospective review of the senior author’s patients produced 16 patients under the age of 21 that had post-traumatic elbow contracture releases. Three patients with arthroscopic releases and one patient lost to follow up were excluded from this study. Twelve adolescent patients (mean age 16.7 years, range 13–21) had open release of post-traumatic elbow contractures. All releases were initiated through a lateral approach with anterior capsular release and were supplemented by posterior release (in 4 patients) through the same incision. Medial-sided pathology was addressed through a separate medial incision in 3 patients. In three patients the radial head was excised. Muscle lengthening was used in only one patient. The mean follow-up was 18.9 months (range 10–42 months). Preoperative flexion was increased from 113 to 129deg (p< 0.01), extension from −51 to −15deg (p< 0.001) for a mean total gain of 54deg in the flexion-extension arc (p< 0.001). Pronation was improved from 58 to 77deg and supination from 56 to 62deg, but these improvements did not reach statistical significance. At the final follow-up the patients maintained 93% of the motion that was achieved intraoperatively. All patients achieved a functional ROM of at least 100deg in the flexion-extension arc. No patient lost motion. One patient had a superficial infection that was treated conservatively. Our experience with post-traumatic contracture release in adolescent patients has been rewarding; all patients reached a functional range of motion. The advantage of the lateral approach used in these patients is that it allows simple and safe access to the anterior capsule, which is often adequate to regain full extension. Through the same approach the posterior structures can also be addressed without violating the lateral collateral ligament. The medial approach is more demanding and was reserved only for patients with medial sided pathology. Fractional musculotendinous lengthening was rarely necessary in post-traumatic contractures. Open release in adolescent patients with congruent stiff elbows has yielded satisfactory results in our hands

The purpose of this study was to determine if arthroscopic release is safe and effective in the management of elbow contracture. Twenty patients (mean age of forty-two), undergoing arthroscopic contracture release were retrospectively reviewed at a minimum follow-up of one year (mean twenty-five months). Most patients had combined extrinsic & intrinsic causes for contractures. Mean flexion improved from 122 to 137°. Mean extension improved from 38° to 18°. The mean arc improvement was 35° (p < 0.001). None of the patients had instability and there were no major neuro-vascular complications. All patients had decreased pain and improved elbow function. To determine if arthroscopic release is safe and effective in the management of elbow contracture. Twenty patients (mean age of forty-two), undergoing arthroscopic contracture release were retrospectively reviewed at a minimum follow-up of one year (mean twenty-five months). Most patients had combined extrinsic & intrinsic causes for contractures. Motion and strength were measured with standard goniometry and the LIDO isokinetic system by independent evaluators. Mean flexion improved from 122 ± 16° to 137 ± 12°. Mean extension improved from 38 ± 18° to 18 ± 14°. The mean arc improvement was 35 ± 21° (p < 0.001). Arthroscopic release did not affect forearm rotation or strength. One patient developed a permanent medial antebrachial cutaneous neuroma. One patient required a repeat surgery to remove a loose body. There were no instability and no major neurovascular complications. All patients had improved elbow function with a mean ASES score of thirty-one out of thirty-six. Most patients were satisfied with their surgery, had minimal pain, considered themselves in good physical health on the SF-36, and had minimal impairment on the DASH. Arthroscopic release is safe and effective in experienced hands. Results are comparable to traditional open techniques. The theoretical advantages of arthroscopy include improved joint visualization, decreased morbidity and earlier rehabilitation. Disadvantages include the potential for serious neurovascular complications, and the inability to deal with ulnar nerve pathology or heterotopic ossification. Indications for conversion to open release include excessive swelling, and failure to maintain adequate view

While the definition of “stiffness” after shoulder arthroplasty remains controversial, loss of range of motion in the post-arthroplasty setting can be a disabling functional complication. Fortunately, the incidence of post-operative loss of both active and passive range of motion is relatively less common following shoulder replacement procedures. Certain pre-operative diagnoses (proximal humeral fracture, capsulorraphy arthropathy, revision arthroplasty) are associated with post-operative soft tissue contractures. Certain medical comorbidities (diabetes, inflammatory arthropathy) are associated with periarticular capsular adhesions at the intracellular level. Management of the “stiff” shoulder arthroplasty must account for several confounding variables: . Appropriateness of diagnosis leading to arthroplasty. Humeral and glenoid implants (size, version, hemi vs TSA vs RSA). Bone variables (fracture, bone loss/erosion). Soft tissue variables (rotator cuff, glenohumeral capsule). Patient comorbidities. Techniques for management include soft tissue contracture release (manipulation, arthroscopic, open) and component revision

Introduction:. The cavovarus foot is a complex deformity caused by muscle imbalance, soft-tissue contracture and secondary bony abnormality. It is a combination of hindfoot, midfoot and forefoot deformity and the decision making process for surgical management can be difficult. The process of deciding which combination of procedures is required is often poorly understood. We present an algorithm to assist with this decision making. Methods:. We have analysed a single surgeon's experience of cavovarus foot correction, from a consecutive series of 50 patients over 5 years, to develop an algorithm to guide operative decision making. Cases included cavovarus deformity secondary to cerebral palsy, Friedreich's ataxia, Charcot Marie Tooth disease, post-traumatic contracture, post-cerebrovascular accident, iatrogenic post-surgery and physiological cavus. We have taken a systematic approach to each component of the deformity in order to generate the algorithm. Results:. To assist in rationalising the traditional ‘a-la-carte’ approach, our algorithm describes what we believe are the indications for a variety of surgical interventions, including soft tissue contracture release, osteotomies of the hindfoot, midfoot and forefoot, tendon transfer and soft tissue balancing, and arthrodesis. We detail the decision making process for each surgical option and give the reasons for each decision. We have also reviewed the available literature on this topic, to produce an evidence-based and useable tool for surgical planning. Conclusion:. The surgical decision making process in the management of the cavovarus foot is complex. We believe that this algorithm, based on extensive personal experience and up-to-date published evidence, provides a clear and proven framework on which surgical decision making can be guided and justified

Aims. In order to release the contracture band completely without damaging normal tissues (such as the sciatic nerve) in the surgical treatment of gluteal muscle contracture (GMC), we tried to display the relationship between normal tissue and contracture bands by magnetic resonance neurography (MRN) images, and to predesign a minimally invasive surgery based on the MRN images in advance. Methods. A total of 30 patients (60 hips) were included in this study. MRN scans of the pelvis were performed before surgery. The contracture band shape and external rotation angle (ERA) of the proximal femur were also analyzed. Then, the minimally invasive GMC releasing surgery was performed based on the images and measurements, and during the operation, incision lengths, surgery duration, intraoperative bleeding, and complications were recorded; the time of the first postoperative off-bed activity was also recorded. Furthermore, the patients’ clinical functions were evaluated by means of Hip Outcome Score (HOS) and Ye et al’s objective assessments, respectively. Results. The contracture bands exhibited three typical types of shape – feather-like, striped, and mixed shapes – in MR images. Guided by MRN images, we designed minimally invasive approaches directed to each hip. These approaches resulted in a shortened incision length in each hip (0.3 cm (SD 0.1)), shorter surgery duration (25.3 minutes (SD 5.8)), less intraoperative bleeding (8.0 ml (SD 3.6)), and shorter time between the end of the operation and the patient’s first off-bed activity (17.2 hours (SD 2.0)) in each patient. Meanwhile, no serious postoperative complications occurred in all patients. The mean HOS-Sports subscale of patients increased from 71.0 (SD 5.3) to 94.83 (SD 4.24) at six months postoperatively (p < 0.001). The follow-up outcomes from all patients were “good” and “excellent”, based on objective assessments. Conclusion. Preoperative MRN analysis can be used to facilitate the determination of the relationship between contracture band and normal tissues. The minimally invasive surgical design via MRN can avoid nerve damage and improve the release effect. Cite this article: Bone Jt Open 2024;5(9):776–784

Hinged external fixators of the elbow joint can be a valuable tool in managing complicated trauma associated with instability, instability after contracture release, and distraction interposition arthroplasty or distraction arthroplasty alone. This retrospective study focuses on the performance of the device in acute and chronic elbow instability associated with complex injuries around the elbow. Thirteen hinged external fixators were applied in 13 patients with an average age of 46 years. All fixators were applied for various types of fractures around the elbow joint associated with elbow dislocation. In 12 patients prior to the application of the fixator, a formal open reduction and internal fixation was performed so as to neutralise the whole construct and permit early mobilisation of the joint. In one patient with a minimally displaced fracture which required no internal fixation the fixator was used to permit early mobilisation. A circular multiplanar frame was used in 4 patients and a unilateral one in the rest of them. Eight out of 13 patients with fracture-dislocation had an uneventful outcome. Three patients required a revision surgery to correct a fracture malalignment and a subluxation of the joint. The results were evaluated according to the Mayo Elbow Performance score. Complications included 4 cases of pin tract infection and 2 of transient ulnar neuritis. Despite the complexity of its application and the complications that may follow such device, an articulating external fixator can be a valuable tool in treating complex elbow instability

We reviewed two similar groups of patients with medial osteoarthritis of the knee treated by unicompartmental arthroplasty. The group receiving an Oxford meniscal-bearing implant, with no medial release, showed significantly better mechanical alignment than that receiving a fixed-bearing implant. Under-correction, with its ominous mechanical implications, was much more common with the fixed-bearing design. Over-correction was rare and was seen in both designs about equally. Degenerative stenosis of the intercondylar notch was common and appeared to put the anterior cruciate ligament at risk of rupture, especially after correction of the varus deformity. We consider that postoperative leg alignment and soft-tissue balance after unicompartmental knee replacement are determined more by the implant design and the surgical technique than by any variation in soft-tissue contracture. Release of the medial collateral ligament is not necessary for realignment, but a generous notchplasty is often needed to allow normal anterior cruciate ligament function

Full-thickness burns around the knee can involve the extensor mechanism. The gastrocnemius flap is well described for soft tissue reconstruction around the knee. We describe a method where a Whichita Fusion Nail¯ knee arthrodesis, combined with a medial gastrocnemius muscle flap was used to salvage the knee and preserve the lower leg following a full-thickness contact burn. The gastrocnemius flap for wound coverage of an open knee joint was originally described in 1970 and remains the workhorse for soft tissue knee reconstruction. There are a number of local alternatives including the vastus lateralis, medialis and sartorius flap; and perforator flaps such as the medial sural artery perforator island flap and islanded posterior calf perforator flap, however many of these are unsuitable for larger defects. Full-thickness burns around the knee can put the extensor mechanism at risk and subsequent rupture is a possible consequence. The gastrocnemius flap has been used to cover a medial knee defect with exposed joint cavity following a burn and also been used in post burn contracture release around the knee. The primary indication for Wichita fusion nail is a failed total knee replacement. It allows intramedullary stabilization with compression at the arthrodesis site to stimulate bone union. With fusion rates reported up to 100% and low complication rates as compared to other methods of fusion, the technique has a useful role in limb salvage type procedures. While use of the gastrocnemius flap in knee burns has been described before we believe this is the first time that this combination of techniques, namely knee arthrodesis with soft tissue reconstruction using a gastrocnemius flap, has been reported. Combining these procedures with a multidisciplinary approach provides a useful alternative leading to limb salvage and avoiding the need for an above knee amputation when extensor reconstruction is not possible

Aims

Multiple secondary surgical procedures of the shoulder, such as soft-tissue releases, tendon transfers, and osteotomies, are described in brachial plexus birth palsy (BPBP) patients. The long-term functional outcomes of these procedures described in the literature are inconclusive. We aimed to analyze the literature looking for a consensus on treatment options.

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 report early (two-year) postoperative findings from a randomized controlled trial (RCT) investigating disease-specific quality of life (QOL), clinical, patient-reported, and radiological outcomes in patients undergoing a total shoulder arthroplasty (TSA) with a second-generation uncemented trabecular metal (TM) glenoid versus a cemented polyethylene glenoid (POLY) component.

Aims

Brachial plexus injury (BPI) is an often devastating injury that affects patients physically and emotionally. The vast majority of the published literature is based on surgeon-graded assessment of motor outcomes, but the patient experience after BPI is not well understood. Our aim was to better understand overall life satisfaction after BPI, with the goal of identifying areas that can be addressed in future delivery of care.

Post-traumatic elbow stiffness is a disabling condition that remains challenging for upper limb surgeons. Open elbow arthrolysis is commonly used for the treatment of stiff elbow when conservative therapy has failed. Multiple questions commonly arise from surgeons who deal with this disease. These include whether the patient has post-traumatic stiff elbow, how to evaluate the problem, when surgery is appropriate, how to perform an excellent arthrolysis, what the optimal postoperative rehabilitation is, and how to prevent or reduce the incidence of complications. Following these questions, this review provides an update and overview of post-traumatic elbow stiffness with respect to the diagnosis, preoperative evaluation, arthrolysis strategies, postoperative rehabilitation, and prevention of complications, aiming to provide a complete diagnosis and treatment path.

Aims

The Precice intramedullary limb-lengthening system has demonstrated significant benefits over external fixation lengthening methods, leading to a paradigm shift in limb lengthening. This study compares outcomes following antegrade and retrograde femoral lengthening in both adolescent and adult patients.

Aims

Animal models have been developed that allow simulation of post-traumatic joint contracture. One such model involves contracture-forming surgery followed by surgical capsular release. This model allows testing of antifibrotic agents, such as rosiglitazone.

The medial rotation contracture caused by weak external rotation secondary to obstetric brachial plexus injury leads to deformation of the bones of the shoulder. Scapular hypoplasia, elevation and rotation deformity are accompanied by progressive dislocation of the humeral head. Between February and August 2005, 44 children underwent a new surgical procedure called the ‘triangle tilt’ operation to correct this bony shoulder deformity. Surgical levelling of the distal acromioclavicular triangle combined with tightening of the posterior glenohumeral capsule (capsulorrhaphy) improved shoulder function and corrected the glenohumeral axis in these patients. The posture of the arm at rest was improved and active external rotation increased by a mean of 53° (0° to 115°) in the 40 children who were followed up for more than one year.

There was a mean improvement of 4.9 points (1.7 to 8.3) of the Mallet shoulder function score after surgical correction of the bony deformity.

We retrospectively reviewed 89 consecutive patients (45 men and 44 women) with a mean age at the time of injury of 58 years (18 to 97) who had undergone external fixation after sustaining a unilateral fracture of the distal humerus. Our objectives were to determine the incidence of heterotopic ossification (HO); identify risk factors associated with the development of HO; and characterise the location, severity and resultant functional impairment attributable to the presence of HO.

HO was identified in 37 elbows (42%), mostly around the humerus and along the course of the medial collateral ligament. HO was hazy immature in five elbows (13.5%), mature discrete in 20 (54%), extensive mature in 10 (27%), and complete bone bridges were present in two elbows (5.5%). Mild functional impairment occurred in eight patients, moderate in 27 and severe in two. HO was associated with less extension (p = 0.032) and less overall flexion-to-extension movement (p = 0.022); the flexion-to-extension arc was < 100º in 21 elbows (57%) with HO compared with 18 elbows (35%) without HO (p = 0.03). HO was removed surgically in seven elbows.

The development of HO was significantly associated with sustaining a head injury (p = 0.015), delayed internal fixation (p = 0.027), the method of fracture fixation (p = 0.039) and the use of bone graft or substitute (p = 0.02).HO continues to be a substantial complication after internal fixation for distal humerus fractures.
