Purpose of the study: Construction of a key grip is the final objective of programmed functional surgery of the upper limb in the tetraplegic. Three phases are necessary: activation of the grip, simplification of the poly-articular chain, and positioning the thumb column. For this operative phase, two techniques can be used, either fusion of the articulation with a trapezometacarpal arthrodesis (TMA) or a soft tissue procedure (tenodesis of the abductor pollicis longus). Our study compared analytically these two techniques, considering grip force and stability and the quality of the key grip opening.

Material and methods: This was a retrospective study of 38 key grips with a mean follow-up of 7.4 years in a population of tetraplegic patients (groups 1 – 5 in the International Classification of Giens. Seventeen active key grips including 11 with TMA and 21 passive key grips including 16 without TMA with regulation of the thumb position by soft tissue procedures. The active and passive grips according to the procedures were comparable statistically for their median ASIA motor scores.

Results: The force of the active key grips with TMA (mean 2.7± 1.3 kg) was significantly greater than that obtained after tenodesis (1.3±0.7 kg) (p=0.05). For passive key grips, the difference was not significant, 1.1±0.6 kg with TMA versus 1.0±0.9 kg without. Twenty-three percent of the grips were unstable after TMA versus 24% after tenodesis. Regarding grip opening, the mean distance between the pulp of the thumb and the index was 3.7 cm for active key grips after TMA by tenodesis effect and 5.4 cm for holding large objects while without TMA these values were 3.2 cm and 6.4 cm respectively. For passive grips, these same values were 2.2 and 3.4 cm after TMA versus 2.4 and 6.8 after tenodesis.

Discussion: For the active key grip, TMA enables a stronger grip but with loss of opening distance for large objects. Conversely, for the passive key grip, TMA does not enable a stronger grip but significantly limits passive opening. Globally TMA yields a more constant result. In patients with a limited motor potential, it is important to favour the creation of two different grips.

Purpose of the study: From November 2001 to January 2008, among 110 patients who underwent surgery for spastic hands due to a central neurological disorder, the management involved surgical treatment of long finger intrinsic and extrinsic deformities in 57 brain injury adults.

Material and methods: At least one procedure for the intrinsics and one for the extrinsics was performed during the same operative. Twelve patients had bilateral operations. The goal of the surgery and the treatment was established during multidisciplinary consultations with rehabilitation physicians, neurologists, surgeons and anaesthesists after a minute physical examination with selective neuromuscular blocks to differentiate muscle spasicity and tendon retraction from extrinsic and intrinsic disorders. The objective was established in the form of a contract with the patient and the family: hygiene and analgesia (47 patients), aesthetic aspect (15 patients, and/or function (21 patients.) For the spasticity and/or retraction of the exrinsics, we used 23 transfers of the FCP to the FCS, 6 Z lengthening of the FCP and the FCS, 14 intramuscular lengthening of the FCP and 11 of the FCS, 10 Page interventions, 10 selecive muscle disinsertions from the epitrochlears and one FCS tenotomy. Concerning the spasticity and/ol retraction of the intrinsic, we performed 4 neurotomies of the deep motor branch of the ulnar nerve, 48 interosseous tenotomise, 6 proximal disinsertions with mobilisation of the interosseous, 18 tenotomies of the 5th adductor, and 29 distal tenotomise of the extensor system.

Results: Outcome was good for 60 of the 69 operated hands (achievement of contract: function 18, aesthetic 14, hygiene 44). Seven hands required revision with a good final result for six of them. One patient developed reflex dystrophy.

Discussion: In adults, despite the modest functional results achieved in only one-third of the patients, corrective surgery for spastic mixed extrinsic and intrinsic deformities provides an important improvement for these patients.

Reconstruction of deficient bone stock during total elbow arthroplasty in rheumatoid arthritis represents a challenge for the surgeon. Fracture and osteolysis of the olecranon process is a very rare condition in rheumatoid arthritis. The consequence of a deficient olecranon is an instable and painful elbow. We report a case of successful olecranon reconstruction with bone graft associated to total elbow arthroplasty with a 8 years follow up and discuss surgical aspects.

This case concerns a 44 years old woman with a very severe rheumatoid arthritis. She complains of pain and instability of her right elbow. X-rays show fracture and major osteolysis of the olecranon process with only some persistent bone at the insertion of the triceps tendon. The humeral condyles were subluxated posteriorly.

We performed a total elbow replacement with a GSB3 implant and reconstruction of the olecranon with two cancellous iliac bone strut fixed by 2.7 diameter screws to the proximal ulna. The triceps tendon with remnant olecranon bone chips was secured to the bone graft by tension band wiring. Postoperatively, the elbow was immobilized for 3 weeks.

With a follow up of more than 8 years the elbow is pain free with excellent function. The active range of motion of flexion – extension is 140° / −20°. The elbow is stable and triceps function is very satisfying authorizing the use of crutches. X-rays show good bony integration of the reconstructed olecranon process and no signs of loosening of the GSB3 implant.

The literature concerning olecranon reconstruction during total elbow arthroplasty in rheumatoid patients is very poor. Kamineni and Morrey reported on one case of olecranon reconstruction with strut allograft in revision total elbow arthroplasty with an unsatisfying result. Their fixation technique was different. We prefer an autograft whenever it is possible and we recommend our fixation technique using screws and tension band wiring.

Purpose: The approach chosen for total elbow arthrolysis is crucial. It should allow access to all lesions causing joint stiffness yet avoid excessive mutilation. We report our experience with the transhumeral approach respecting the lateral structures.

Material and methods: Thirteen transhumeral elbow arthrolyses were performed from 1996 to 2002 and reviewed retrospectively at mean 18 months (6–63). Mean age at surgery was 44 years. Stiffness resulted from trauma in five patients and degenerative disease in eight. The SOFCOT classification was severe in two, moderate in ten and minimal in one. Arthroysis was performed by the posterior transtricipital technique. After releasing the fossa and the olecranon beak, the coronoid process and the anterior capsule were released using a transhumeral bone window. Two patients also underwent ulnar nerve transposition. Rehabilitation was initiated early and continued for 17 weeks on average.

Results: At last follow-up, active elbow extension improved from −39±9° to 21±9° and flexion from 109±14° to 129±7°, corresponding to an increase in motion of 38±14° (70° preoperatively and 108° postoperatively). This gain in motion was the same in the trauma and degeneration groups. Pain, evaluated with a visual analogue scale from 0 to 10 improved from 3.2±1.3 to 2.4±2.0 for posttraumatic stiffness and from 7.4±1.3 to 4.1±2.0 for degenerative stiffness. There was on postoperative irritation of the ulnar nerve which regressed partially.

Discussion: Transhumeral arthrolysis allows posterior and anterior release while preserving the lateral structures. This technique has been very effective for olecranon bone blockage, posterior and anterior capsule retraction, and for coronoid anterior block. For degenerative elbows, pain relief was achieved in 70%.

Conclusion: Transhumeral elbow arthrolysis initially proposed for the degenerative elbow can be used for posttraumatic stiffness in patients with a moderate form without limiting pronosupination nor injuring the lateral ligaments. The best indication is fracture of the humeral plate.

Purpose: Functional outcome after shoulder arthrodesis was evaluated to assess indications for the treatment of posttraumatic partial and total brachial plexus paralysis in adults.

Material and methods: Twenty-seven patients who underwent glenohumeral arthrodesis for posttraumatic brachial plexus paralysis were reviewed. Eleven had radicular paralysis (C5, C6 and C5, C6, C7) and sixteen total paralysis. All patients recovered active elbow flexion. Shoulder reinnervation had failed in eleven patients. Before the arthrodesis, 22 patients could no use their paralysed limb. Mean time between direct neurological surgery and arthrodesis was 30 months for partial paralyses and 20 months for total paralyses. Glenohumeal screw fixation was used for the arthrodesis which was associated with an external fixation in 21.

Results: Mean postoperative follow-up was 70 months. There were two cases of non-union which fused after revision and three cases of humerus fracture which occurred during the first six months after surgery. Pain related to inferior subluxation improved in six patients. There was no significant difference between the two groups for position of the fusion, or postoperative active motion (60° flexion, 60° abduction, 45° internal rotation and 7 to −9° external rotation). There was a significant difference in force which was greater for superior paralyses (11 kgf versus 7 kgf in flexion, 12 kfg versus 7 kgf in abduction, 6 kgf versus 2 kgf in external rotation and 11 kgf versus 4 kgf in internal rotation). The same was true for hand movement. The differences were statistically correlated with force of the pectoralis major.

Conclusion: Glenohumeral arthrodesis provides significant improvement in function in patients with supraclavicular brachial plexus paralysis, even with a paralytic hand. Arthrodesis also allows reorienting surgical reinnervation to other functions such as hand movement. Shoulder force and hand movement are directly correlated with force of the pectoralis major.

Purpose: Scapulohumeral arthrodesis is principally indicated for plexus brachial paralysis. It is a controversial indication with limited use for non-neurological conditions. We report a series of shoulder arthrodeses performed for non-neurological conditions searching for the appropriate indications for this procedure.

Material and methods: The series included nine patients, six men and three women, mean age 48 years (23–89). The dominant side was fused in three and the non-dominant in six. Seven patients had had at least one operation prior to arthrodesis. The procedure was performed in one patient to remove a foreign body in a prosthetic cuff tendon, in three for off-centred joint degeneration with massive cuff tears and in two for degenerative disease with multidirectional instability. In all patients except one, the posterior approach was used for internal screw fixation associated with external fixation (left in place for 2.5 months on average).

Results: Subjectively, all patients except one were satisfied with the result (mainly because of pain relief). Objectively, active motion was 65° flexion, 65° abduction, 50° internal rotation (mean fusion position 20° flexion, 25° abduction, and 30° internal rotation). Two groups were identified for assessment with the absolute Constant score. The score improved 16 points (24 to 40) in the group without instability (pain score improved from 3 to 13) and decreased 14 points (66 to 52) in patients with instability (attributed to lesser motion, mean motion scores decreasing from 38 to 14). Complications included one case each of radial palsy, non-union, and gravity oedema of the upper limb.

Discussion: Pain relief and stability are not the sole objectives of shoulder arthrodesis. The procedure can also provide useful improvement in function (hand mouth, hand perineum, thoracobrachial clamp. It can be useful if prosthetic arthroplasty cannot be used (infectious arthritis, advanced osteoarthritis in young subjects and failed stabilisation of multidirectional instability). It is a predictable procedure in terms of outcome. We continue to use scapulohumeral arthrodesis for rare indications.

Purpose: Blast injury of the hand generally occurs during manipulations of unstable explosives. The explosion greatly damages the first commissure. The aim of this study was to define a classification system useful for establishing therapeutic strategy.

Material and methods: From 1988 to 2002, we treated eight patients (nine hands, five dominant) with blast injury of the hand. Mean age was 24 years. Five hands were injured during manipulation of firecrackers and four during manipulation of munitions. The thumb was amputated on five hands, including three cases of index or medius amputation. Thumb revascularisation was successful in only one case. Two proximal thumb amputations were treated by twisted toe transfer. For one of these patients, the transfer was prepared by translocation of M2 on M1 using an inguinal flap. Two patients required a composite osteocutaneous reconstruction of M1 using the index as the bone source. In one final patient, lesions were limited to soft tissues.

Discussion: Blast injured hands present several types of lesions: extensive soft tissue damage, diffuse vessel damage making revascularisation difficult or impossible, combined thenar and joint lesions leading to secondary closure of the first commissure. We distinguished three stages. Stage 1 involves only muscle and skin damage. After opening the first commissure with M1-M2 pinning, cover is achieved with a posterior interosseous flap or a skin graft. Stage 2 involves osteoarticular damage. Bone loss of M1 and P1 is often associated with dislocation. Bone reconstruction is often achieved using the distally amputated or greatly damaged thumb. Stage 3 involves amputation or devascularisation of the thumb. Reconstruction of the thumb is particularly difficult in these cases. If the amputation is distal beyond MP, M1 lengthening or classical toe transfer can be used. If the amputation is proximal, prior M1 reconstruction is required with a skin envelope using M2 fashioned with an interosseous or inguinal flap, followed by twisted toe transfer of the second toe. Stage 3 translocations are difficult because of the often damaged index and scar formation.

Purpose: We analysed outcome in a retrospective consecutive series of 30 Kapandju-Sauvé procedures performed between January 1993 and September 2000 for correction of antebrachial injuries (five patients) and distal radioulnar injuries (25 patients).

Material and methods: All patients (mean age 42 years) were reviewed by the same observer at a mean follow-up of 44 months. Mean time from initial trauma to surgery was 26 months.

Results: For the distal radio-ulnar injuries, the objectives were achieved (158° pronation-supination) with preservation of force (73% of healthy side). The Mayo Clinic functional score, as modified, was 72/100 at last follow-up and 24/25 patients were satisfied. For the ante-brachial injuries, outcome was slightly inferior: 110° pro-nation-supination, force 48% of healthy side, functional score 56/100, three out of five patients very satisfied or satisfied, resumed occupational activity in four out of five patients. There were however no cases with an unstable ulnar stump in this group.

Conclusion: This study confirmed the efficacy of the Kapandji-Sauvé procedure for the treatment of sequelae of distal radio-ulnar injuries, particularly in young patients. The novel indication for antebrachial injuries also provided satisfactory results after a simple procedure compared with shaft osteotomy of the two ante-brachial bones.

Purpose: Operative wounds are commonly washed with a more or less diluted antiseptic solution to prevent infection or to treated overt infection. Chlorhexidine is widely used. We report the cases of nine patients who developed joint destruction attributed to peroperative irrigation with a chlorhexidine solution.

Material and methods: Nine patients (three men and six women) who had undergone surgery in another facility were referred to our unit for unexplained postoperative chondrolysis. The joint localisations were: wrists (n=7) after surgery for a dorsal arthrosynovial cyst (mean age 37 years); elbow (n=1) after surgery for epicondylalgia (age 49 years); shoulder (n=1) after arthroscopy for sub-acromial impingement (age 51 years).

The time between surgery and the first consultation in our unit varied from three to nine years (mean five years four months). Persistent stiffness had been noted in the postoperative period with pain at joint mobilisation which worsened progressively. For the patients with chondrolysis of the wrist: the x-rays demonstrated destruction of the radius-first ray joint in one, the medio-carpal joint in four and overall destruction in two. Overall joint destruction was also observed in the elbow and shoulder patients. Search for other causes of joint destruction was negative; infection and inflammatory rheumatoid disease were ruled out. The common feature identified in all patients was joint irrigation with a chlorhexidine solution (Biseptine®).

Results: Four of the nine patients underwent surgical treatment: a four-bone arthrodesis with scaphoidectomy was used for the three patients with mediocarpal involvement and a shoulder arthrodesis was performed in one patient. The pathology study demonstrated cartilage defects filled with dense strongly hyalinised acellular tissue. Bacteriological specimens were all negative.

Discussion: The chondrolytic effect of chlorhexidine, a member of the biguanide family, was first reported in 1986 with a few cases described with knee involvement. Experimentally, there would be a dose-dependent effect. The mechanism involves a disorganisation of the cell membrane with cartilaginous necrosis and ostocartilaginous resorption. Individual predisposition cannot be ruled out.

Conclusion: In light of these observations, it would be advisable to avoid peroperative joint irrigation with chlorhexidine solution.

Purpose: Reactivation of upper limb function in high-tetraplegia patients requires two successive procedures: restoration of elbow extension, then construction of the key grip. Performing both procedures during the same operative time can reduce the operative time. We compared this combined technique with the classical programme, particular for patients requiring transfer of the brachioradialis to construct the key grip.

Material and methods: The study series included 16 upper limbs in 15 tetraplegic patients. Two distinct operative programmes were used. Group A (nine limbs): transfer of the posterior deltoid to the triceps and active key grip by transfer of the brachioradialis on the flexor pollicis longus. According to the Giens classification there were three group 2, five group 3 and one group 4. Group B (seven limbs): transfer of the biceps on the triceps and passive tenodesis key grip. The Giens classification was five group 2 and two group 3. Five of these limbs exhibited supination attitude of the forearm that was treated initially with isolated osteotomy of the radius. Mean follow-up was ten months. A control group underwent the same surgical programmes but with two distinct operative times.

Results: Mean hospital stay was shortened compared with the control group 4.1±0.8 months versus 10±1.0 months). Elbow extension force according to the BMRC scale was 3.8±0.6 in Group A versus 3.5 for the control group and 3.2±0.5 for Group B compared with 2.8 for the control group. Mean active key grip force was 1.8±0.9 kg for Group A versus 1.9 for controls and 0.9±0.6 kg for the passive key grips in Group B versus 0.9 for controls. Functional independence improved postoperatively, the QIF improved from 40.0±18.0 to 55.2±17.0.

Discussion: This work demonstrated that a single operation shortens hospital stay without affecting the final outcome and that the brachioradial can be transferred on the flexor pollicis longus for reactivation of elbow extension. In our experience, only 46% of the tetraplegic patients starting a functional surgery programme benefit from reactivation of the elbow and hand. Procedures performed during a single operation allow a more systematic approach.

Purpose: We evaluated submuscular anterior transposition of the ulnar nerve at the elbow with lengthening of the medial epicondylars as described by Dellon in patients with ulnar nerf deficiency due to compression.

Material and methods: A consecutive series of 30 submuscular tranpositions of the ulnar nerve in 28 patients were performed between 1994 and 1998. Four patients had had a prior procedure (two simple neurolyses, two subcutaneous transpositions). Mean age was 52 years. Preoperative EMB confirmed the diagnosis of ulnar compression at the elbow. All patients has sensorial and/or motor deficits. Postoperative immobilisation was maintained for 15 to 20 days.

Results: The patients were reviewed at a mean follow-up of four years two months. There were no cases of paraesthesia. Improved sensorial function was observed in 71% of the cases (normalisation in 50%) with improvement in the Foment sign and grip in 81.5% (normalisation in 48%). Mean elbow extension was −5°, and flexion was 135°. There was not limitation on wrist amplitudes. The thumb finger force on the operated side was 78% to 94% that measured on the healthy side and was a function of the MacGowan grade. The palm-finger force was 80% to 95% of the healthy side. There has been no recurrence at last follow-up.

Conclusion: Submuscular transposition using the Dellon technique in 30 cases of ulnar nerve compression at the elbow in patients with ulnar deficiency provided satisfactory sensorial and motor recovery. The usefulness of lengthening the medial epicondyls lies in removing the tension on the ulnar nerve and the little effect on elbow and wrist mobility. Submuscular transposition is the technique of choice for repeated neurolysis.
